Objective: Research shows highly palatable foods can elicit addictive eating behaviours or ¿food addiction¿. Early adolescence is theorised to be a vulnerable period for the onset of addictive eating behaviours, yet minimal research has examined this. This study explored the prevalence and correlates of addictive eating behaviours in a large early adolescent sample. Methods: 6640 Australian adolescents (Mage = 12.7 ± 0.5, 49%F) completed an online survey. Addictive eating was measured with the Child Yale Food Addiction Scale (YFAS-C). Negative-binomial generalised linear models examined associations between addictive eating symptoms and high psychological distress, energy drink consumption, sugar-sweetened beverage (SSB) consumption, alcohol use, and cigarette use. Results: Mean YFAS-C symptom criteria count was 1.36 ± 1.47 (of 7). 18.3% of participants met 3+ symptoms, 7.5% endorsed impairment and 5.3% met the diagnostic threshold for food addiction. All examined behavioural and mental health variables were significantly associated with addictive eating symptoms. Effects were largest for high psychological distress and cigarette use; with those exhibiting high psychological distress meeting 0.65 more criteria (95%CI = 0.58¿0.72, p < 0.001) and those who smoked a cigarette meeting 0.51 more criteria (95%CI = 0.26¿0.76, p < 0.001). High psychological distress and consumption of SSB and energy drinks remained significant when modelling all predictors together. Conclusion: In this large adolescent study, addictive eating symptoms were common. Further research should establish directionality and causal mechanisms behind the association between mental ill-health, alcohol and tobacco use, and addictive eating behaviours. Cross-disciplinary prevention initiatives that address shared underlying risk factors for addictive eating and mental ill-health may offer efficient yet substantial public health benefits.

Background: Culinary nutrition education programs are increasingly used as a public health intervention for older adults. These programs often integrate nutrition education in addition to interactive cooking workshops or displays to create programs suitable for older adults¿ needs, ability and behaviour change. Synthesising the existing literature on nutrition education and interactive cooking programs for older adults is important to guide future program development to support healthy ageing. Objectives: To determine the extent of published literature and report the characteristics and outcomes of interactive culinary nutrition education programs for older adults (> 51 years). Design: This scoping review followed the PRISMA-ScR guidelines recommended for reporting and conducting a scoping review. Methods: Five databases were searched of relevant papers published to May 2022 using a structured search strategy. Inclusion criteria included: older adults (= 51 years), intervention had both an interactive culinary element and nutrition education and reported dietary outcome. Titles and abstracts were screened by two reviewers, followed by full-text retrieval. Data were charted regarding the characteristics of the program and outcomes assessed. Results: A total of 39 articles met the full inclusion criteria. The majority of these studies (n= 23) were inclusive of a range of age groups where older adults were the majority but did not target older adults exclusively. There were large variations in the design of the programs such as the number of classes (1 to 20), duration of programs (2 weeks to 2 years), session topics, and whether a theoretical model was used or not and which model. All programs were face-to-face (n= 39) with only two programs including alternatives or additional delivery approaches beside face-to-face settings. The most common outcomes assessed were dietary behaviour, dietary intake and anthropometrics. Conclusion: Culinary nutrition education programs provide an environment to improve dietary habits and health literacy of older adults. However, our review found that only a small number of programs were intentionally designed for older adults. This review provides a summary to inform researchers and policy makers on current culinary nutrition education programs for older adults. It also recommends providing face-to-face alternatives that will be accessible to a wider group of older adults with fewer restrictions.

Introduction: Many university students have poor mental health, and co-occurring health risk behaviors. Targeting health behavior change in this population may improve mental health outcomes. This scoping review describes the extent and range of randomized controlled trials (RCT) evaluating interventions targeting health risk behaviors and measuring a mental health outcome, among university students. Methods: Six electronic databases were searched for RCTs published until the 18th May 2021. Eligible RCTs included university students, evaluated interventions that promoted health behavior change (i.e., dietary intake, physical activity, sedentary behavior, alcohol and drug use, smoking, and sleep), and measured a mental health-related outcome. Results: Fifty-nine RCTs met the inclusion criteria that were published from 2000 to 2021, and over half (n = 33) were conducted in the United States. Interventions evaluated within the RCTs (n = 92) predominantly targeted changes to dietary intake (n = 41 interventions), physical activity (n = 39), or alcohol intake (n = 35). Most interventions targeted one (n = 51) or two (n = 27) health behaviors only. Included RCTs considered mental ill health outcomes (n = 24), psychological wellbeing outcomes (n = 20), or both (n = 15). Discussion: This scoping review identified a moderate volume of experimental research investigating the impact of health behavior interventions on university students' mental health. There is scope for further research examining health behavior interventions targeting university students, particularly interventions taking a multi-behavioral approach.

This study investigated the implementation model and research methods of a peer education program for new parents focused on infant feeding and nutrition. Two hundred and sixty-nine parents with an infant aged birth to two years old were invited to become co-researchers in a Participatory Action Research (PAR) study over three years. Data included focus group and online participant meeting transcripts, social media data, correspondence between the implementation team and peer educators, and field notes. All data were consolidated regularly and discussed by project participants and the research team. After each PAR cycle, structured content analysis was conducted, informing the next iteration of the implementation model and research methods. Participating parents were highly engaged in child feeding peer-to-peer education, but felt more effective and comfortable being considered as a child-feeding information resource sharer or ¿champion¿ rather than a formal peer educator. Similarly, quantitative data collection was only effective when it was integrated seamlessly into the implementation model. PAR methodology suited the diversity and dynamic real-life study setting, facilitating substantial improvements to the peer nutrition intervention model and data collection methods. Our study demonstrated that a genuine collaboration between health professionals and participants to implement research in practice can achieve both intervention outcomes and research aims.

Aim: This rapid review of reviews aimed to determine the extent of research undertaken on the effectiveness of dietary interventions for individuals with a mental disorder. Methods: Three databases (MEDLINE, Embase, Cochrane Reviews and Cochrane Trials) were searched to February 2021 for systematic reviews including experimental studies assessing the effectiveness of dietary interventions with physical or mental health related outcomes in adults or children with one or more of: severe mental illness, depression or anxiety, eating disorders, or substance use disorder. Results are presented descriptively. Results: The number of included reviews was 46 (67% in severe mental illness, 20% in depression and anxiety, 7% in eating disorders, and 7% in substance use disorders). Most reviews were published since 2016 (59%), and included studies conducted in adults (63%). Interventions in the eating disorders and severe mental illness reviews were predominantly education and behaviour change, whereas interventions in the substance use disorders, and depression and anxiety reviews were predominantly supplementation (e.g. omega-3). Twenty-eight and twelve of the reviews respectively reported mental health and dietary outcomes for one or more included studies. Most reviews in severe mental illness, and depression and anxiety reported conclusions supporting the positive effects of dietary intervention, including positive effects on weight-related or mental health outcomes, and on mental health outcomes, respectively. Conclusions: A larger number of systematic reviews were identified which evaluated dietary interventions in individuals with severe mental illness, and depression and anxiety, compared with substance use disorders, and eating disorders. Dietary intervention is an important component of the treatment that should be available to individuals living with mental disorders, to support their physical and mental health.

2D images can be used to capture food intake data in nutrition studies. Estimates of food volume from these images are required for nutrient analysis. Although 3D image capture is possible, it is not commonplace. Additionally, nutrition studies often require multiple food images taken by non-expert users, typically collected using mobile phones, due to their convenience. Current 2D image to 3D volume approaches are restricted by the need for prescribed camera placement, image metadata analysis and/or significant computational resources. A new method is presented combining 2D image capture and automated 3D scene projection with manual placement and resizing of wire mesh objects. 2D images, with a reference object, are taken on low specification mobile phones. 3D scene projection is calculated by twinning a cuboid in 3D space to the reference object in the 2D image. A manually selected 3D wire mesh object is then positioned over the target food item and manually transformed to improve accuracy. The virtual wire mesh object is then projected into the 3D scene and the volume of the target food item calculated. The whole process is computationally light and runs in real-time as an app on a standard Apple iPad. Based on a user study with 60 participants, experimental evaluations of volume estimates over regular shape and ground truth food items demonstrate that this approach provides acceptable accuracy. We demonstrate that the accuracy of estimates can be increased by combining multiple independent estimates.

Introduction Codesign is a meaningful end-user engagement in research design. The integrated knowledge translation (IKT) framework involves adopting a collaborative research approach to produce and apply knowledge to address real-world needs, resulting in useful and useable recommendations that will more likely be applied in policy and practice. In the field of food addiction (FA), there are limited treatment options that have been reported to show improvements in FA symptoms. Objectives The primary aim of this paper is to describe the step-by-step codesign and refinement of a complex intervention delivered via telehealth for adults with FA using an IKT approach. The secondary aim is to describe our intervention in detail according to the TIDieR checklist. Design This study applies the IKT process and describes the codesign and refinement of an intervention through a series of online meetings, workshops and interviews. Participants This study included researchers, clinicians, consumers and health professionals. Primary outcome measure The primary outcome was a refined intervention for use in adults with symptoms of FA for a research trial. Results A total of six female health professionals and five consumers (n=4 female) with lived overeating experience participated in two interviews lasting 60 min each. This process resulted in the identification of eight barriers and three facilitators to providing and receiving treatment for FA, eight components needed or missing from current treatments, telehealth as a feasible delivery platform, and refinement of key elements to ensure the intervention met the needs of both health professionals and possible patients. Conclusion Using an IKT approach allowed for a range of viewpoints and enabled multiple professions and disciplines to engage in a semiformalised way to bring expertise to formulate a possible intervention for FA. Mapping the intervention plan to the TIDieR checklist for complex interventions, allowed for detailed description of the intervention and the identification of a number of areas that needed to be refined before development of the finalised intervention protocol.

Background: Focused antenatal care currently implemented in Tanzania recommends that women receive nutrition care during routine clinic visits. However, little detail is documented in regard to the nutrition information provided to pregnant women during these visits. The present study aimed to investigate whether pregnant women recalled nutrition information or support provided and, if so, who provided this during routine antenatal clinic visits. The secondary aim was to determine how pregnant women intended to implement the information and what mode of delivery was preferred for receiving nutrition information. Methods: An exploratory cross-sectional study comprising exit interviews was conducted with 50 pregnant women attending antenatal clinics in three regional referral hospitals in Dar es Salaam, Tanzania. Results: All participants (n¿=¿50) reported receiving nutrition care from healthcare workers in regard to; haemoglobin checks (79% of participants), iron and folic acid supplementation (70%), weight measurement (70%), eating advice (60%), and dietary intake assessment (38%). However, the information recalled on each category was inconsistent. For 60% of participants, nurses were reported as the source of nutrition care during pregnancy, followed by medical doctors (22%). The most preferable mode for receiving nutrition information was reported as individual face-to-face sessions with health practitioners, followed by mobile phone. All of the participants who received nutrition information indicated that they intended to implement. Conclusions: Nurses were the main source of nutrition information for pregnant women attending antenatal clinics, followed by medical doctors. However, the content of nutrition information recalled by participants was inconsistent. Healthcare facilities need to implement strategies to ensure pregnant women understand and can implement nutrition information provided by healthcare workers during routine antenatal care.

Aim: This scoping review aimed to explore the extent of the evidence of experimental studies evaluating the cost effectiveness of dietary interventions in individuals with mental disorders. Methods: Five databases (CINAHL, EMBASE, MEDLINE, PsycINFO and Scopus) were searched to October 2020 for cost-analysis studies of interventions aiming to improve dietary intake in people with mental disorders. No restriction was placed on participant age, mental disorder type or intervention design. Results are presented narratively. Results: Of 2753 articles identified, 13 articles reporting on eight studies were included. Studies were RCTs (n¿=¿5), cluster RCT (n¿=¿1), cluster preference RCT (n¿=¿1), and pre-post test (n¿=¿1). Seven studies were in community settings (eg, outpatient clinics), and one study in the community housing setting. All studies were in adults, seven included male and female participants, and one included only females. Defined mental disorder diagnoses included serious/severe mental disorders (n¿=¿3), major depression (n¿=¿2), schizophrenia, schizoaffective disorder or first-episode psychosis (n¿=¿1), any mental disorder (n¿=¿1), and bulimia nervosa (n¿=¿1). Five interventions were multi-behaviour, two were diet only and one was eating disorder treatment. Cost analyses included cost-utility (n¿=¿3), cost-effectiveness (n¿=¿1), cost-utility and cost-effectiveness (n¿=¿3), and a costing study (n¿=¿1). Two studies (25%) reported positive results in favour of cost effectiveness, and four studies reported a mix of positive and neutral results. Conclusions: There is limited evidence evaluating the cost effectiveness of dietary interventions in individuals with mental disorders. Additional studies in various settings are needed to confirm cost effectiveness of different interventions.

Due to global advances in technology, image-based food record methods have emerged as an alternative to traditional assessment methods. The use of image-based food records in low and lower-middle income countries such as Tanzania is limited, with countries still using traditional methods. The current study aimed to determine the feasibility of using a new voice and image-based dietary assessment system (VISIDA) in Dar es Salaam, Tanzania. This mixed-method study recruited 18 nutritionists as participants who collected image-based records of food and drinks they consumed using the VISIDA smartphone app. Participants viewed an online demonstration of the VISIDA web platform and the analysis process for intake data collected using the VISIDA app. Then, participants completed an online survey and were interviewed about the VISIDA app and web platform for food and nutrient intake analysis. The method was reported as being acceptable and was found to be easy to use, although technical challenges were experienced by some participants. Most participants indicated a willingness to use the VISIDA app again for one week or longer and were interested in using the VISIDA system in their current role. Participants acknowledged that the VISIDA web platform would simplify some aspects of their current job. Image-based food records could potentially be used in Tanzania to improve the assessment of dietary intake by nutritionists in urban areas. Participants recommended adding sound-on notifications, using the VISIDA app in both Apple and Android phones, enabling installation from the app store, and improving the quality of the fiducial markers.

Diet quality is influenced by demographics and can change over time. This study aimed to (1) compare diet quality among adolescents/adults who completed the online Healthy Eating Quiz (HEQ) by demographic characteristics, and (2) to evaluate change in score over time for repeat completers. HEQ data collected between July 2016 and May 2022 were analysed, including demographics (age, gender, vegetarian status, socio-economic status, number of people main meals are shared with, country), and diet quality calculated using the Australian Recommended Food Score (ARFS) (range 0¿73) for respondents aged = 16 years. Differences in ARFS by demographic characteristics and change in score over time, adjusted for age, gender and vegetarian status, were tested by linear regression. The participants (n = 176,075) were predominantly female (70.4%), Australian (62.8%), and aged 18¿24 years (27.7%), with 4.0% (n = 7087) repeat completers. Mean ± SD ARFS was 33.9 ± 9.4/73. Results indicate that ARFS was significantly lower among males and significantly higher with increasing age group, higher socio-economic status, in vegetarians, those who shared main meals with others, and those living in Australia (p-values < 0.001). Mean change in ARFS over time (2.3 ± 6.9) was significantly higher for those with lower baseline scores (p < 0.001). Publicly available, brief dietary assessment tools have the potential to improve diet quality at the population level.

(1) Background: Research suggests that certain foods may have addictive effects; however, no reviews have systematically appraised studies in this area. The aims of this review were to determine the nutrients, foods and dietary patterns associated with addictive eating. (2) Methods: Published studies up to November 2020 were identified through searches of 6 electronic databases. Eligible studies included those in in children and adults that reported dietary intakes of individuals with ¿food addiction¿. (3) Results: Fifteen studies (n = 12 in adults and n = 3 in children/adolescents with Yale Food Addiction Scale defined ¿food addiction¿) were included. Foods commonly associated with addictive eating were those high in a combination of fat and refined carbohydrates. Generally, intakes of energy, carbohydrates and fats were significantly higher in individuals with addictive eating compared to those without. (4) Conclusions: Due to the heterogeneity in study methodologies and outcomes across included studies, it is difficult to conclude if any specific foods, nutrients or dietary patterns facilitate an addictive process. Further research is needed to elucidate potential associations. However, present addictive eating treatment approaches could incorporate individualised dietary advice targeting foods high in fat and refined carbohydrates.

Objective: To investigate associations between eating behavior constructs (social eating, perceived competence, habit automaticity, self-determined motivation) and diet quality among young adults. Design: Cross-sectional analysis. Participants: Young adults (n = 1,005; mean age, 21.7 ± 2.0 years; 85% female) enrolled in the Advice, Ideas, and Motivation for My Eating (Aim4Me) study. Main outcome measures: Four eating behavior measures collected via online surveys: Social Eating Scale, Perceived Competence in Healthy Eating Scale, Self-Report Behavioral Automaticity Index, and Regulation of Eating Behaviors scales. Diet quality was assessed using the Australian Recommended Food Score (ARFS) and percentage energy from energy-dense, nutrient-poor (EDNP) foods. Analysis: Multivariate linear regression investigating associations between eating behavior measures (independent variables) and ARFS and EDNP foods (dependent variables), adjusting for sociodemographic and lifestyle confounders. Results: Greater perceived competence in healthy eating and behavioral automaticity for consuming healthy foods, limiting EDNP food intake, and higher intrinsic motivation, integrated regulation, and identified regulation of eating behaviors were associated with higher ARFS and lower percentage energy EDNP foods (P < 0.001). Greater self-reported social influence on eating behaviors was associated with higher ARFS (P = 0.01). Higher amotivation was associated with greater % energy from EDNP foods (P < 0.001). Conclusions and Implications: Perceived competence, habit automaticity, and self-determined motivation are determinants of diet quality in young adults. These findings support the development of interventions that promote healthy eating habits by focusing on eating behavior constructs and evaluating their use in improving diet quality.

Aim: Understanding neural responses through functional magnetic resonance imaging (fMRI) to food and food cues in middle-older adults may lead to better treatment options to address the growing issue of malnutrition. This scoping review aimed to determine the extent, range and nature of research using fMRI, related to reward-based regions, in response to food cues in middle to older aged adults (50 years and over). Methods: The following databases were systematically searched in July 2019: CINAHL, CENTRAL, Embase, Dissertations and Theses, Ovid Medline, PsycINFO, PsycEXTRA, Scopus and Web of Science. Studies were eligible for inclusion if participants had a mean or median age =50 years, utilised and reported outcomes of either a food cue task-related fMRI methodology or resting-state fMRI. Data from included studies were charted, and synthesised narratively. Results: Twenty-two studies were included. Eighteen studies utilised a task-related design to measure neural activation, two studies measured resting state neural connectivity only and an additional two studies measured both. The fMRI scanning paradigms, food cue tools and procedure of presentation varied markedly. Four studies compared the neural responses to food between younger and older adults, providing no consensus on neural age-related changes to food cues; two studies utilised longitudinal scans. Conclusion: This review identified significant extent, range and nature in the approaches used to assess neuronal activity in response to food cues in adults aged 50 years and over. Future studies are needed to understand the age-related appetite changes whilst considering personal preferences for food cues.

Gastrointestinal (GI) toxicities are common in patients receiving radiotherapy (RT) to the pelvis. This systematic review aims to evaluate the effectiveness of nutritional interventions involving dietary counselling (DC) on GI toxicities in patients receiving pelvic RT. The search method entailed two phases to retrieve studies. Articles from a previous Cochrane review by Lawrie et al. 2018 were assessed for inclusion. An updated systematic search was then conducted to retrieve articles published between 2013 and 2020 from five electronic databases (MEDLINE, EMBASE, CINAHL, CENTRAL and Scopus). The inclusion criteria entailed randomised controlled trials involving adults =18¿years, undergoing curative pelvic RT, receiving a nutritional intervention involving DC with or without supplements. DC was defined as written or face-to-face dietary advice provided before or during RT. Outcomes included GI toxicities reported by validated assessment tools. The Academy of Nutrition and Dietetics Quality Criteria Checklist was utilised to assess quality and risk of bias. Of 1922 studies retrieved, 12 articles encompassing 11 individual RCTs were included. Seven studies included a supplement in addition to DC. Supplements included probiotics, prebiotics, probiotic + soluble fibre, high protein liquid supplement and fat emulsion. Of the 11 studies, one involved individualised DC, and the remaining studies prescribed consumption or avoidance of fats, fibre, lactose, protein and FODMAP. The most common toxicities reported were diarrhoea (n¿=¿11), pain/cramping (n¿=¿9) and bloating/flatulence (n¿=¿5). Three studies stated an improvement in diarrhoea incidence. Results varied between studies. Further quality studies are required to assess the effectiveness of DC, in particular individualised DC on GI toxicities in patients receiving pelvic RT.

Nutrition plays an important role in pain management. Healthy eating patterns are associated with reduced systemic inflammation, as well as lower risk and severity of chronic non-cancer pain and associated comorbidities. The role of nutrition in chronic non-cancer pain management is an emerging field with increasing interest from clinicians and patients. Evidence from a number of recent systematic reviews shows that optimising diet quality and incorporating foods containing anti-inflammatory nutrients such as fruits, vegetables, long chain and monounsaturated fats, antioxi-dants, and fibre leads to reduction in pain severity and interference. This review describes the current state of the art and highlights why nutrition is critical within a person-centred approach to pain management. Recommendations are made to guide clinicians and highlight areas for future research.

Background: Adequate nutrition is essential in individuals with diabetic foot ulceration (DFU); therefore, an assessment of dietary intake is critical. A lack of nutrients including protein, zinc and vitamins C and D have all been associated with poor wound healing. However, the comprehensive dietary intake of Australian adults with DFU is poorly understood. The aim of this cross-sectional study was to describe the dietary intake of adults with DFU in an Australian setting. Methods: Participants (n = 115) with diabetes (type 1 and 2), a mean body mass index of 36 and current foot ulceration were recruited from across New South Wales, Australia. Dietary intake was assessed using the Australian Eating Survey, a self-reported validated food frequency questionnaire. Results: The mean (SD) reported energy intake was 9.57 (±SD 4.43) MJ¿day¿1. A mean protein intake of 104 (±SD 49) g¿day¿1 is below recommended intake for wound healing; however, the mean protein intake contribution to energy (19%E) was within recommendations for normal populations. The mean carbohydrate intake (43%E) was within recommended ranges for healthy populations; however, the mean total fat intake (36%E) was above recommendations. Micronutrient intake was adequate, apart from folate, which was below the recommended intake, and sodium, vitamin C, vitamin A and selenium, which were above the recommended intake. Conclusions: A lack of adequate folate may have a negative impact on healing, with folate proposed to play a role in tissue repair. Wound management of individuals with DFU should include a regular assessment of dietary intake to recognise deficiencies in macro- and micronutrients, and subsequently address these inadequacies to optimise healing.

Background & aims: Postprandial lipaemic response has emerged as a risk factor for cardiovascular disease. Dietary fats such as medium-chain saturated fatty acids (MCSFA) and long-chain omega-3 polyunsaturated fatty acids (LCn-3PUFA) are known to reduce postprandial lipaemic responses. The combination of the two could potentially have complementary and/or synergistic effects for optimising cardiovascular health. This study aims to investigate the effects of MCSFA (coconut oil) with or without LCn-3PUFA (fish oil) inclusion in the test meal on postprandial blood lipids in healthy adults. Methods: In a randomised, double-blinded, placebo-controlled, 2 × 2 factorial cross-over study, participants (n = 15) were randomised to receive four standardised isocaloric test meals. Test meals include: placebo [PL, containing no fish oil (0 g EPA & DHA) or coconut oil (0 g MCSFA)], fish oil [FO, 6 g fish oil (3.85 g EPA & DHA), containing no coconut oil (0 g MCSFA)], coconut oil [CO, 18.65 g coconut oil (15 g MCSFA), containing no fish oil (0 g EPA & DHA)] and coconut oil + fish oil [COFO, 18.65 g coconut oil (15 g MCSFA) + 6 g fish oil (3.85 g EPA & DHA)]; all providing a total fat content of 33.5 g. Participants received all four treatments on four separate test days with at least 3 days washout in between. Blood parameters were measured by finger pricks at 7 timepoints between 0 and 300min. The primary outcome of this study was the change in postprandial triglycerides (TG) concentrations with secondary outcomes as total cholesterol, high-density lipoprotein cholesterol and blood glucose concentrations. Results: TG area under the curve (AUC) (mmol/L/min) was significantly lower for FO (383.67, p = 0.0125) and COFO (299.12, p = 0.0186) in comparison to PL (409.17) only. TG incremental area under the curve (iAUC) (mmol/L/min) was significantly lower with COFO (59.67) in comparison to CO (99.86), (p = 0.0480). Compared to PL, the change in absolute TG concentrations (mmol/L) from baseline to post TG peak time (180min) after FO were significantly less at 240min (0.39 vs 0.15), 270min (0.2 vs 0.1), and 300min (0.28 vs 0.06), and after COFO was significantly less at 300min (0.28 vs 0.16) (p < 0.05). No significant differences in postprandial AUC and iAUC for any other blood parameters were reported. Conclusions: Our study demonstrated that LCn-3PUFA with or without MCSFA but not MCSFA alone are effective in reducing postprandial TG in healthy individuals.

Introduction: Innovative eHealth solutions that improve access to child weight management interventions are crucial to address the rising prevalence of childhood obesity globally. The study aimed to evaluate the feasibility and preliminary efficacy of a 12-week online telehealth nutrition intervention to improve child weight and dietary outcomes, and the impact of additional text messages (SMS) targeted to mothers and fathers. Methods: Families with children aged 4 to 11 were randomised across three groups: Telehealth, Telehealth+SMS, or Waitlist control. Telehealth and Telehealth+SMS groups received two telehealth consultations delivered by a dietitian, 12 weeks access to a nutrition website and a private Facebook group. The Telehealth+SMS group received additional SMS. Feasibility was assessed through recruitment, retention, and intervention utilisation. Efficacy was assessed through changes in measured child body mass index (BMI), waist circumference and diet. Results: Forty-four (96%) and 36 (78%) families attended initial and second telehealth consultations, respectively. Thirty-six families (78%) completed week 12 assessments. Child BMI and waist circumference changes from baseline to week 12 were not statistically different within or between groups. Children in Telehealth+SMS had significantly reduced percentage energy from energy-dense nutrient-poor food (95% CI -21.99 to -0.03%E; p =.038) and increased percentage energy from healthy core food (95% CI -0.21 to 21.89%E; p =.045) compared to Waitlist control. Discussion: A family-focused online telehealth nutrition intervention is feasible. While the modest sample size reduced power to detect between-group changes in weight status, some improvements in child dietary intakes were identified in those receiving telehealth and SMS.

Introduction: Previous reviews of family-based interventions for childhood obesity treatment found that studies were of low methodological quality with inadequate details reported, especially related to intervention fidelity. The evaluation of fidelity is crucial to inform interpretation of the intervention outcomes. This study aimed to summarise intervention fidelity, participants¿ acceptability and satisfaction with a 12-week family-focused technology-based child nutrition and weight management intervention. Methods: Families with children aged 4¿11 years participated in a telehealth intervention with complementary components: website, Facebook group and text messages. Intervention fidelity was reported using National Institutes of Health Treatment Fidelity Framework. Delivery was measured using a dietitian-reported evaluation survey. Google Analytics and Bitly platform were used to objectively track data on frequency and pattern of intervention use. Participants¿ acceptability and satisfaction were measured using a process evaluation survey. Results: Telehealth consultations delivered by trained dietitians had good adherence (=83%) to the structured content. Process evaluation results indicated that parents (n = 30; mean age 41 years, 97% were female, body mass index 30 kg/m2) found the intervention components easy to use/understand (87¿100%), the programme had improved their family/child eating habits (93%), and they wanted to continue using telehealth and the website, as well as recommending it to other parents (90¿91%). Discussion: In summary, a family-focused technology-based child nutrition and weight management intervention using telehealth, website, Facebook and SMS can be delivered by trained dietitians with good fidelity and attain high acceptability and satisfaction among families with primary-school-aged children in New South Wales, Australia.

Recent research has employed deep learning to detect intake gestures from inertial sensor and video camera data. However, the fusion of these modalities has not been attempted. The present research explores the potential of fusing the outputs of two individual deep learning inertial and video intake gesture detection models (i.e., score-level and decision-level fusion) using the test sets from two publicly available multimodal datasets: (1) OREBA-DIS recorded from 100 participants while consuming food served in discrete portions and (2) OREBA-SHA recorded from 102 participants while consuming a communal dish. We first assess the potential of fusion by contrasting the performance of the individual models in intake gesture detection. The assessment shows that fusing the outputs of individual models is more promising on the OREBA-DIS dataset. Subsequently, we conduct experiments using different score-level and decision-level fusion approaches. Our results from fusion show that the score-level fusion approach of max score model performs best of all considered fusion approaches. On the OREBA-DIS dataset, the max score fusion approach (F1 = 0.871) outperforms both individual video (F1 = 0.855) and inertial (F1 = 0.806) models. However, on the OREBA-SHA dataset, the max score fusion approach (F1 = 0.873) fails to outperform the individual inertial model (F1 = 0.895). Pairwise comparisons using bootstrapped samples confirm the statistical significance of these differences in model performance (p&#x003C;.001).

Aim: The aim of this study was to comprehensively assess dietary intake, nutrition knowledge and food addiction in young people with mental illness. Methods: This was a three-arm cross-sectional study of 16¿25-year-olds attending community mental health services who met criteria for: (i) first-episode psychosis (FEP), (ii) ultra-high risk for psychosis (UHR) or (iii) depression/anxiety. Participants self-completed three validated questionnaires: (i) Australian Eating Survey, (ii) General Nutrition Knowledge Questionnaire¿Revised and (iii) Yale Food Addiction Score Questionnaire. Results: Thirty participants (mean age 19.7 ± 2.5 years) completed the study (10 per study arm); 43% of the energy intake was obtained from energy-dense, non-nutritious foods, higher than the recommended upper limit (<15%) and the levels reported in the general population (35%). Mean diet quality score was 33.5 ± 11.8 of 73. Mean food addiction symptom score was 3.3 ± 3.7. Prevalence of food addiction was 37%. Nutrition knowledge was lower in the FEP and UHR participants than the depression/anxiety group (48.2 ± 13.8 and 49.5 ± 8.2 of 88 respectively); however, this difference was not statistically significant. Conclusions: Unhealthy dietary intake was observed in the early stages of mental illness, likely seeding future poor physical health. Further research is needed on the role of food addiction in this population, including effective intervention techniques.

In human research, images of food are often used as cues in place of real foods. To elicit anticipatory responses in targeted populations (e.g. prompting changes in metabolic hormones, invoking food cravings), cultural differences and population norms with regard to food preferences need to be considered. This pilot study aimed to construct two image paradigms (healthy vs. hyperpalatable foods) for experimental use within the Australian population. A dataset of 200 images (from the licenced database Food-pics and internet sources), representative of healthy and hyperpalatable foods commonly consumed in Australia, was compiled by research dietitians. Ten male and female adults volunteered to view the images. Participants categorised each image as either healthy food or ¿junk food¿ (i.e. hyperpalatable food), and rated each image according to three criteria: 1) familiarity of the food displayed; 2) recognisability of the food; and 3) appetisingness of the food. Overall, agreement with a priori categories was high for both healthy and hyperpalatable food images, 87.3% and 87.7% respectively. The food images with the lowest overall ratings (score <7 out of possible 9) were removed from the dataset and the final paradigms each contain 75 images. The healthy food paradigm contains foods from the five core food groups (fruit, vegetables, grains and cereals, meat and meat alternatives, dairy foods), and the hyperpalatable food paradigm contains non-core foods (sweet and savoury discretionary choice foods). The paradigms represent a broad range of commonly consumed foods that will be relevant for prospective projects utilising food cues in Australian adults.

Dietary supplementation with curcumin has been previously reported to have beneficial effects in people with insulin resistance, type 2 diabetes (T2D) and Alzheimer¿s disease (AD). This study investigated the effects of dietary supplementation with curcumin on key peptides implicated in insulin resistance in individuals with high risk of developing T2D. Plasma samples from participants recruited for a randomised controlled trial with curcumin (180 mg/day) for 12 weeks were analysed for circulating glycogen synthase kinase-3 ¿ (GSK-3¿) and islet amyloid polypeptide (IAPP). Outcome measures were determined using ELISA kits. The homeostasis model for assessment of insulin resistance (HOMA-IR) was measured as parameters of glycaemic control. Curcumin supplementation significantly reduced circulating GSK-3¿ (-2.4 ± 0.4 ng/mL vs. -0.3 ± 0.6, p = 0.0068) and IAPP (-2.0 ± 0.7 ng/mL vs. 0.4 ± 0.6, p = 0.0163) levels compared with the placebo group. Curcumin supplementation significantly reduced insulin resistance (-0.3 ± 0.1 vs. 0.01 ± 0.05, p = 0.0142) compared with placebo group. Dietary supplementation with curcumin reduced circulating levels of IAPP and GSK-3¿, thus suggesting a novel mechanism through which curcumin could potentially be used for alleviating insulin resistance related markers for reducing the risk of T2D and AD.

Background & aims: Chronic inflammation drives the development of insulin resistance and type 2 diabetes. Long-chain omega-3 polyunsaturated fatty acids (LCn-3PUFA) eicosapentaenoic acid (EPA, c20:5n-3) and docosahexaenoic acid (DHA, c22:6n-3) may protect against type 2 diabetes development. The aim of this current study is to determine whether LCn-3PUFA status is associated with type 2 diabetes in the Hunter Community Study. Methods: Men and women aged 55¿85 years were randomly selected from the electoral roll and invited to participate. Participants were included in the current study if they had plasma phospholipid fatty acid composition data available and diabetes status could be determined. LCn-3PUFA status was determined by fatty acid composition of plasma phospholipids (EPA + DHA, %,w/w). Diabetes was determined according to World Health Organisation criteria. Insulin was measured in n = 251 participants and HOMA-IR calculated. Results: In total, n = 2092 (diabetes: n = 249) participants were included. After adjusting for confounders of diabetes, LCn-3PUFA status was inversely associated with diabetes in overweight/obese females (OR [95%CI]: 0.90 [0.80, 1.00], p = 0.045) but not males (p-interactionsex = 0.041). Overweight/obese females with diabetes had significantly lower levels of DHA than those without diabetes (mean difference [95%CI]: -0.53 [-0.87, -0.20], p = 0.002), with no difference in EPA. LCn-3PUFA was inversely associated with HOMA-IR (r = -0.175, p = 0.005). Conclusions: This study provides further evidence of a sex-dependent association between LCn-3PUFA and type 2 diabetes. Causal pathways between LCn-3PUFA and type 2 diabetes merits delineation.

Objective: To (i) describe the adaptation of the Short Food Survey (SFS) for assessing the dietary intake of children (2-5 years) during attendance at Early Childhood Education and Care (SFS-ECEC); (ii) determine the acceptability and feasibility of the SFS-ECEC; and (iii) compare the SFS-ECEC to direct observations for assessing dietary intake of children in care.Design: The adapted forty-seven-item SFS-ECEC was completed by childcare educators to capture individual child's usual intake over the past month. Acceptability and feasibility were assessed via educator self-report and completion rates. Mean servings of food groups consumed in accordance with dietary guidelines reported in the SFS-ECEC were compared to those obtained by a single-day direct observation via visual estimation conducted by trained personnel. Mean differences, intra-class correlations, Bland-Altman plots, percentage agreement and Cohen's ¿ were examined.Setting: Early Childhood Education and Care, NSW, Australia.Participants: Educators and children.Results: 213 (98·61 %) SFS-ECECs were returned. Acceptability was high with 86·54 % of educators reporting the tool as easy to understand. Mean differences in servings of food groups between the SFS-ECEC and direct observation were statistically significantly different for five out of six foods and ranged 0·08-1·07, with intra-class correlations ranging 0·00-0·21. Agreement between the methods in the classification of children meeting or not meeting dietary guidelines ranged 42·78-93·01 %, with Cohen's ¿ ranging -0·03 to 0·14.Conclusions: The SFS-ECEC is acceptable and feasible for completion by childcare educators. While tool refinement and further validation is warranted, small mean differences suggest the tool may be useful in estimating group-level intakes.

Background: Recent research has demonstrated an association between dietary intake and sleep health that can influence chronic disease risk factors. A scoping review of research studies investigating dietary intake and sleep was undertaken to determine the extent and scope of research in laboratory-based, free-living and mixed settings. Additionally, this review determines how well subpopulations and geographical locations are represented and the methodologies used to assess outcome measures. Methods: Five online databases were used to identify papers published between 1970 and 2017. Included studies were those conducted in adults and reported both outcomes of interest: (i) sleep health, including sleep restriction and sleep hygiene and (ii) dietary outcomes, including altered nutrients, dietary patterns and supplements. Results: In total, 129 publications were included with the majority¿being dietary interventions investigating sleep outcomes (n¿=¿109) with fewer¿being sleep interventions investigating and reporting dietary outcomes (n¿=¿20). Dietary interventions were most often carried out in free-living environments, in contrast to sleep interventions that were most often carried out in laboratory-based environments. The majority of dietary interventions investigated use of a supplement (n¿=¿66 studies), which was predominantly caffeine (n¿=¿49). Sleep interventions investigated sleep duration only, with the majority (n¿=¿17) investigating the effect of partial sleep restriction under 5.5¿h per night on dietary intake,¿while three studies investigating total sleep deprivation. Conclusions: Investigating broader aspects of dietary such as overall diet quality and dietary patterns and other components of sleep health such as quality, timing and sleep¿hygiene are important aspects for future research.

Assessing energy intake (EI) in children and adolescents is essential for monitoring population nutrition trends and interpreting clinical outcomes. The aim of this review was to examine the validity of dietary assessment methods for estimating EI in children and adolescents when compared with total energy expenditure (TEE) measured using doubly labelled water (DLW). Six online databases were searched to identify articles published in English. Studies were included if they were conducted in participants aged =18 years, if they estimated EI via a dietary assessment method, and if they compared this estimate to TEE measured using the DLW method. The search strategy identified 345 articles, of which 13 articles (12 studies) (n = 306 children) met the selection criteria. Five studies were carried out in children aged 5¿11 years with dietary intake of children reported by parents/caregivers. The most common dietary assessment methods used were food frequency questionnaires (n = 5) and weighed food records (n = 4). All methods were found to have some level of misreporting. Child characteristics including weight status, age, and sex were not found to consistently influence the accuracy of reported EI. Five studies employing technology-assisted approaches for assessing dietary intake in children were identified and reported mixed findings. Validity studies using DLW remain sparse in the literature. Studies including participants less than 5 years or older than 11 years, and from diverse ethnicities and socioeconomic backgrounds are warranted to explore other demographic differences that may affect the accuracy of dietary assessment methods. While reported in few studies, technology-assisted methods were found to perform equally well in estimating intakes when compared to DLW and other traditional forms of dietary assessment.

Background & aims: A brief assessment tool on frequency and variety of fruit and vegetable intake could provide a cost-effective and sustainable approach to improving diet. The primary aim was to evaluate the comparative validity of a brief index of Fruit And Vegetable VAriety (FAVVA) relative to food and nutrient intakes derived from a comprehensive food frequency questionnaire (FFQ). The secondary aim was to evaluate the FAVVA index in relation to fasting plasma carotenoid concentrations. Methods: Dietary intakes and fasting plasma carotenoid concentrations of 99 overweight and obese adults (49.5% female; 44.6 ± 9.9 years) were assessed at baseline and 3-months. Food and nutrient intakes were assessed using the Australian Eating Survey (AES) FFQ. The FAVVA index was derived from a sub-set of 35 AES questions related to fruit and vegetable intake frequency and variety. Associations were assessed using Spearman's correlation coefficients and linear regression analysis, and agreement using weighted kappa (K w ). Results: Total FAVVA score demonstrated moderate to strong, significant (all p < 0.01) correlations with total daily intakes of vegetables (r = 0.75), vitamin C (r = 0.71), fruit (r = 0.66), vitamin A (r = 0.49), fibre (r = 0.49), potassium (r = 0.46), magnesium (r = 0.39), iron (r = 0.26), riboflavin (r = 0.24), calcium (r = 0.23), zinc (r = 0.20) and niacin equivalent (r = 0.20). These associations remained significant in the adjusted regression analyses and agreement testing. Total FAVVA was significantly correlated with plasma carotenoid concentrations (µg/dL) of a¿carotene (r = 0.22, p < 0.01), ß¿carotene (r = 0.26, p < 0.001), ß¿cryptoxanthin (r = 0.22, p < 0.01) and total carotenoids (r = 0.18, p < 0.05). The associations with a¿carotene (ß = 0.09, p < 0.001), ß¿carotene (ß = 0.42, p < 0.05) and total plasma carotenoids (ß = 0.85, p < 0.05) remained significant in the adjusted regression analyses and for agreement testing. Conclusions: FAVVA is suitable as a brief tool to rank frequency and variety of fruit and vegetable intake.

Aim: There has been an increase in the use of text messaging to deliver and support health interventions. The aim was to develop a bank of text messages targeting healthy eating for children in the context of parenting partnerships that could be used in a family intervention. Methods: Text messages were developed using the Theoretical Domains Framework and Behaviour Change Wheel COM-B model by study investigators using a three-phase approach: (i) initial development of a message bank; (ii) messages were reviewed and evaluated by experts and parents on their clarity, usefulness, and relevance using a 5-point Likert scale and open text spaces for additional feedback and (iii) refinement of messages content and finalised the message bank. Results: Messages were reviewed for ¿clarity¿, ¿usefulness¿ and ¿relevance¿ by 20 parents and 28 health experts, who were predominantly female (92%), parents of primary school age children (33%), of low to middle socioeconomic status (78%), with a mean age of 39 years (SD ± 9.87). From an initial set of 97 messages developed, 48 messages were retained through consultation. Messages were designed to complement the intervention, while engaging both parents. Conclusions: The three-phase development created a set of text messages acceptable to experts and parents that aim to support improvement in child eating behaviours. The process provides a template and practical guide for researchers and health providers looking to apply a systematic approach to text messages development. Future research should investigate acceptability and impact of these messages as a component of family-based nutrition intervention.

The objective of this review was to evaluate the efficacy and safety of very low-energy diet (VLED) programs for weight loss in children and adolescents with obesity. Six electronic databases were searched identifying 24 eligible studies (16 pre-post studies, four nonrandomized trials, two randomized controlled trials [RCTs], and two chart reviews) published up to October 2018. Studies were in English, implemented a VLED (=3360¿kJF/day [=800¿kcal/day] or <50% estimated energy requirements) in 5- to 18-year-olds with obesity, and reported at least one weight-related outcome. Weight-related outcomes significantly improved postintervention in all studies. Meta-analysis of 20 studies indicated a mean 10.1¿kg (95% confidence interval [CI], 8.7-11.4¿kg, P¿<¿0.001; I2¿=¿92.3%) weight loss following interventions lasting 3 to 20¿weeks. Moderator analysis indicated greater weight loss in adolescent-only studies (10-18¿years) and formulated meal replacement interventions and inpatient settings. Meta-analysis of seven studies reporting weight at follow-up (5-14.5¿months from baseline) indicated 5.3 kg mean weight loss (CI, 2.5-8.0¿kg, P¿<¿0.001; I2¿=¿50.6%). Details of adverse events were limited. VLED programs are effective for treating children and adolescents with obesity. However, conclusions on their safety cannot be drawn from the existing literature at this time. Future studies should include long-term follow-up with ongoing support and comprehensive monitoring of all adverse events.

Background Severe mental illness (SMI) is thought to be associated with lower diet quality and adverse eating behaviours contributing towards physical health disparities. A rigorous review of the studies looking at dietary intake in psychotic disorders and bipolar disorder is lacking.Aims To conduct a systematic, comprehensive evaluation of the published research on dietary intake in psychotic disorders and bipolar disorder.Method Six electronic databases were searched for studies reporting on dietary intakes in psychotic disorders and bipolar disorder. Dietary-assessment methods, and dietary intakes, were systematically reviewed. Where possible, data was pooled for meta-analysis and compared with healthy controls.Results In total, 58 eligible studies were identified. People with SMI were found to have significantly higher dietary energy (mean difference 1332 kJ, 95% CI 487-2178 kJ/day, P = 0.002, g = 0.463) and sodium (mean difference 322 mg, 95% CI 174-490 mg, P < 0.001, g = 0.414) intake compared with controls. Qualitative synthesis suggested that higher energy and sodium intakes were associated with poorer diet quality and eating patterns.Conclusions These dietary components should be key targets for preventative interventions to improve weight and other physical health outcomes in people with SMI.Declaration of interest S.B.T. and E.T. have clinical dietitian appointments within the South Eastern Sydney Local Health District and do not receive any further funding.

The aim of this study was to examine the effect of a six-week 2 × 2 design on pain scores, quality of life, and dietary intake in patients attending an Australian tertiary pain clinic. The two intervention components were (1) personalized dietary consultations or waitlist control, and (2) active or placebo dietary supplement (fruit juice). Sixty participants were randomized into one of four groups at baseline (68% female, mean age 49 ± 15 years) with 42 completing the study (70% retention). All groups had statistically significant improvements in three of five pain outcomes. The personalized dietary consultation groups had clinically important improvements in three of five pain outcomes compared to the waitlist control groups. All groups had a statistically significant improvement in six of eight quality-of-life categories post intervention. All groups increased percentage energy from nutrient-dense foods (+5.2 ± 1.4%, p < 0.001) with a significant group-by-time effect for percentage energy from total fat (p = 0.024), with the personalized dietary consultations plus placebo fruit juice reporting the largest reduction (-5.7 ± 2.3%). This study indicates that dietitian-delivered dietary intervention can improve pain scores, quality of life, and dietary intake of people experiencing chronic pain. Future research should evaluate efficacy in a full-powered randomized control trial.

Background: Unhealthy diets are typical of university students and the effects may be wider reaching than health. The present study aimed to describe the association between dietary intake and academic achievement in a sample of Australian university students. Methods: A cross-sectional analysis of data from an online survey of 278 students from the University of Newcastle (UON), Australia [mean (SD) age 26.9¿(10.5)¿years; 70.9% female] was conducted. Dietary intake, in terms of diet quality score [Australian Recommended Food Score (ARFS)], including individual sub-scales, and percentage energy per day from energy-dense nutrient poor (EDNP) foods, including individual sub-groups, was assessed using the validated Australian Eating Survey Food Frequency Questionnaire, and academic achievement was assessed as self-reported grade point average (GPA). The association between GPA and dietary intake was explored using linear regression, with adjustment for socio-demographic and student characteristics. Results: Higher GPA was associated with higher diet quality (ARFS) (ß¿=¿0.02, P¿=¿0.011), higher sub-scale scores for vegetables (ß¿=¿0.03, P¿=¿0.026) and fruit (ß¿=¿0.05, P¿=¿0.029) and with lower percentage energy per day from EDNP foods overall (ß¿=¿-0.01, P¿=¿0.047) and also from sweetened drinks (ß¿=¿-0.06, P¿<¿0.001). Conclusions: The results of the present study demonstrate small associations between a healthier dietary intake and higher academic achievement, as well as vice versa. Given that the associations were small, they may not be particularly meaningful. However, this evidence could be used as a motivator for efforts aiming to improve dietary intake among university students.

Introduction: The concept of ¿food addiction¿ (FA) has gained popularity in view of clinical and neurobiological overlaps between excessive food intake and addictive disorders. However, no studies have examined the link between FA and striatocortical circuits involved in addictive disorders, or the influence of homeostatic status, which regulates the drive to eat, on these systems. This study aims to investigate changes in striatal functional connectivity between fasted and fed conditions among adults ranging in body mass index (BMI) and FA symptoms. Methods: Thirty adults were recruited from the general community and completed self-reported surveys including demographics, FA symptoms using the Yale Food Addiction Scale, as well as height and weight measures, used to determine BMI. Participants completed two 3-T MRI scans, one in a fasted state and one in a fed state. We conducted seed-based analyses to examine between-session (¿fasted > fed¿) change in resting-state functional connectivity of the ventral and dorsal striatum, and its association with FA scores (controlling for BMI). Results: Higher symptoms of FA correlated with greater changes in ventral caudate-hippocampus connectivity between fasted and fed conditions. FA symptoms did not correlate with connectivity in the dorsal caudate circuit. Post-hoc analyses revealed that participants with higher symptoms of FA had ventral caudate-hippocampus hyperconnectivity in the fasted scan only, as well as a significant reduction of this connectivity between the fasted and fed scans. Conclusions: Heightened connectivity in the ventral striatum during a fasted state, which has been linked to reward prediction signals, underpins symptoms of FA. In contrast, connectivity in the dorsal striatum or ¿habit¿ system is unrelated to homeostatic status and FA symptoms, and is thus less relevant for subclinical manifestations of FA.

Food ingestion is heavily implicated in inducing symptoms of irritable bowel syndrome (IBS) and functional dyspepsia (FD), which affect over one-third of adults in developed countries. The primary aim of this paper was to assess the alignment of dietary assessment and symptom-reporting capture periods in diet-related studies on IBS or FD in adults. Secondary aims were to compare the degree of alignment, validity of symptom-reporting tools and reported significant associations between food ingestion and symptoms. A five-database systematic literature search resulted in 40 included studies, from which data were extracted and collated. The food/diet and symptom capture periods matched exactly in 60% (n = 24/40) of studies, overlapped in 30% (n = 12/40) of studies and were not aligned in 10% (n = 4/40) of studies. Only 30% (n = 12/40) of studies that reported a significant association between food and global gastrointestinal symptoms used a validated symptom-reporting tool. Of the thirty (75%) studies that reported at least one significant association between individual gastrointestinal symptoms and dietary intake, only four (13%) used a validated symptom tool. Guidelines to ensure that validated symptom-reporting tools are matched with fit-for-purpose dietary assessment methods are needed to minimise discrepancies in the alignment of food and symptom tools, in order to progress functional gastrointestinal disorder research.

Objective A wide variety of methods are available to assess dietary intake, each one with different strengths and weaknesses. Researchers face multiple challenges when diet and nutrition need to be accurately assessed, particularly in the selection of the most appropriate dietary assessment method for their study. The goal of the current collaborative work is to present a collection of available resources for dietary assessment implementation.Design/Setting/Participants As a follow-up to the 9th International Conference on Diet and Physical Activity Methods held in 2015, developers of dietary assessment toolkits agreed to collaborate in the preparation of the present paper, which provides an overview of each toolkit. The toolkits presented include: the Diet, Anthropometry and Physical Activity Measurement Toolkit (DAPA; UK); the National Cancer Institute's (NCI) Dietary Assessment Primer (USA); the Nutritools website (UK); the Australasian Child and Adolescent Obesity Research Network (ACAORN) method selector (Australia); and the Danone Dietary Assessment Toolkit (DanoneDAT; France). An at-a-glance summary of features and comparison of the toolkits is provided.Results The present review contains general background on dietary assessment, along with a summary of each of the included toolkits, a feature comparison table and direct links to each toolkit, all of which are freely available online.Conclusions This overview of dietary assessment toolkits provides comprehensive information to aid users in the selection and implementation of the most appropriate dietary assessment method, or combination of methods, with the goal of collecting the highest-quality dietary data possible.

OBJECTIVES: The objective of the review was to synthesize the effectiveness and strategies used in family-based behavioral childhood obesity interventions in improving child weight-related outcomes. INTRODUCTION: Family-based interventions are common practice in the treatment of childhood obesity. Research suggests that direct parental involvement can improve child weight-related outcomes. However, challenges remain in assessing the effects of family-based interventions on child weight and weight-related behavior due to the lack of quality programs and diversity of treatment strategies. INCLUSION CRITERIA: The review included systematic reviews and/or meta-analyses of family-based behavioral interventions in children aged =18 who were classified as overweight and/or obese, and which reported child weight related outcomes, such as body mass index (BMI), body fat percentage and waist circumferences. METHODS: Seven databases were searched from 1990 to May 2016 to identify English language publications. Reference lists of included reviews and relevant registers were also searched for additional reviews. All included systematic reviews were critically appraised by two reviewers independently. Data extracted included characteristics of included systematic reviews and weight-related outcomes reported. Data synthesis involved categorizing the interventions into seven categories and presented findings in narrative and tabular format. Quality of evidence was assessed using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach. RESULTS: The umbrella review included 14 systematic reviews (low to moderate methodological quality), published between 2004 and 2015, including 47 independent trials ranging from one month to seven years follow-up conducted in more than 16 countries. The majority of reviews (93%) reported weight outcomes of children aged six to 13 years. All reviews except one indicated that family-based interventions were successful in improving child weight and/or weight-related behavior. Five reviews highlighted that parent-only interventions had similar (n¿=¿4) or greater (n¿=¿1) effectiveness compared to parent-child interventions. Effective interventions employed parent-targeted strategies, including nutrition and physical activity education sessions, positive parenting skills, role modelling and child behavior management to encourage positive healthy eating/exercise behaviors in children and/or whole family. CONCLUSIONS: Family-based interventions targeting parents, alone or with their child, are effective for child weight management. Due to the lack of high quality evidence, especially in emerging parent-only interventions, further research is warranted. Health practitioners can work with parents as agents of change and focus on fostering positive parenting skills, such as monitoring, reinforcement, role modelling, and providing a nurturing environment, in order to support health behaviors in their children. Future research needs to explore whether parent-only interventions are more cost-effective compared to parent-child interventions, and to include larger populations, longer intervention duration and follow-up.

Background: This systematic review aimed to evaluate the impact of nutrition interventions on participant reported pain severity and intensity in populations with chronic pain. Methods: Eight databases were systematically searched for studies that included adult populations with a chronic pain condition, a nutrition intervention and a measure of pain. Where possible, data were pooled using meta-analysis. Seventy-one studies were included, with 23 being eligible for meta-analysis. Results: Studies were categorised into four groups: (i) altered overall diet with 12 of 16 studies finding a significant reduction in participant reported pain; (ii) altered specific nutrients with two of five studies reporting a significant reduction in participant reported pain; (iii) supplement-based interventions with 11 of 46 studies showing a significant reduction in pain; and (iv) fasting therapy with one of four studies reporting a significant reduction in pain. The meta-analysis found that, overall, nutrition interventions had a significant effect on pain reduction with studies testing an altered overall diet or just one nutrient having the greatest effect. Conclusions: This review highlights the importance and effectiveness of nutrition interventions for people who experience chronic pain.

The neuropeptide oxytocin has been associated with food intake and feeding behaviour. This systematic review aimed to investigate the impact of oxytocin on dietary intake and feeding behaviour in rodent studies. Six electronic databases were searched to identify published studies to April 2018. Preclinical studies in mice and rats were included if they reported: (1) a dietary measure (i.e. food or nutrient and/or behaviour (2) an oxytocin measure, and (3) relationship between the two measures. A total of 75 articles (n = 246 experiments) were included, and study quality appraised. The majority of studies were carried out in males (87%). The top three oxytocin outcomes assessed were: exogenous oxytocin administration (n = 126), oxytocin-receptor antagonist administration (n = 46) and oxytocin gene deletion (n = 29). Meta-analysis of exogenous studies in mice (3 studies, n = 43 comparisons) and rats (n = 8 studies, n = 82 comparisons) showed an overall decrease in food intake with maximum effect shown at 2 h post-administration.

Healthy Dads Healthy Kids (HDHK) was the first program internationally to specifically target overweight and obese fathers to improve their children's health. In previous randomized controlled trials, HDHK generated meaningful short-Term improvements in the adiposity, physical activity, and eating behaviors of both fathers and children. The aim of this dissemination trial was to evaluate the 12-month impact of HDHK when delivered by trained facilitators across four low socioeconomic and regional communities in the Hunter Region, Australia. The study was a nonrandomized, prospective trial with minimal eligibility criteria (i.e., father body mass index [BMI] ? 25 kg/m2 and children aged 4-12 years). HDHK included eight weekly practical and theoretical sessions. Assessments were baseline, 3 months (post-intervention), 6-months, and 12-months. The primary outcome was fathers' weight. Secondary outcomes included child BMI z-score and validated lifestyle behavior measures (e.g., physical activity, diet). Overall, 189 fathers (mean age: 40.2 years, BMI: 32.6 kg/m2) and 306 children (mean age: 8.1 years) participated in one of 10 HDHK programs in four areas. Intention-To-Treat linear mixed models revealed a significant mean reduction in fathers' weight at post-intervention (?3.6 kg, 95% confidence interval: ?4.3, ?2.9), which was maintained at 12 months (71% retention). Corresponding improvements were also detected in children's BMI z-score and a range of lifestyle behaviors for both fathers and children. Attendance and satisfaction levels were high. Positive intervention effects observed in previous randomized controlled trials were largely replicated and sustained for 12 months when HDHK was delivered by trained local facilitators in underserved communities. Further investigation into the key systems, processes, and contextual factors required to deliver HDHK at scale appears warranted.

Background and aims: Given the increasing prevalence of childhood obesity in Malaysia, examination of family environmental factors is warranted. Reviews from developed countries report inconsistent findings on the relationship between parental-child feeding practices and child weight-related health outcomes. The current study aimed to examine parent-child feeding practices by familial-child characteristics in Malaysia. Materials and method: The Family Diet Study was conducted with urban Malay families and included a child aged 8¿12 years and their main carer(s). Seven domains of parent-child feeding practices were assessed using the child feeding questionnaire and familial demographics, including socio-economic status, child anthropometry and dietary intake were collected. Inferential statistics were used to explore the relationships between variables. Results: Of the 315 families enrolled, 236 completed all measures, with the majority of parent-reporters being mothers (n = 182). One-third of the children were classified as overweight/obese. Three domains of parent-child feeding practices had median scores of 4.0 out of 5.0 [concern about child overweight (CCO) (Interquartile range (IQR): 3.3, 4.7); pressure-to-eat (PTE) (IQR: 3.3, 4.5) and food monitoring (IQR: 3.0, 5.0)]. The domain of ¿perceived child overweight¿ was positively associated with child age (r = 0.45, p < 0.001). Children who were overweight (F = 37.4; p < 0.001) and under-reported energy intake (F = 13.1; p = 0.001) had higher median scores for the parental perception of risk of child being overweight. Median scores for the CCO and PTE domains were significantly higher in low-income families (F = 7.87; F = 9.75; p < 0.05, respectively). Conclusion: Malay parents in this present study are concerned about their child's weight, particularly for those overweight. Family size, household income, and child weight status significantly influence parent-child feeding practices. Further research examining the cultural context of family environmental factors related to childhood obesity is warranted within Malaysia.

Aim: To compare the theoretical costs of best-practice weight management delivered by dietitians in a traditional, in-person setting compared to remote consultations delivered using eHealth technologies. Methods: Using national guidelines, a framework was developed outlining dietitian-delivered weight management for in-person and eHealth delivery modes. This framework mapped one-on-one patient¿dietitian consultations for an adult requiring active management (BMI = 30 kg/m2) over a one-year period using both delivery modes. Resources required for both the dietitian and patient to implement each treatment mode were identified, with costs attributed for material, fixed, travel and personnel components. The resource costs were categorised as either establishment or recurring costs associated with the treatment of one patient. Results: Establishment costs were higher for eHealth compared to in-person costs ($1394.21 vs $90.05). Excluding establishment costs, the total (combined dietitian and patient) cost for one patient receiving best-practice weight management for 12 months was $560.59 for in-person delivery, compared to $389.78 for eHealth delivery. Compared to the eHealth mode, a higher proportion of the overall recurring delivery costs was attributed to the patient for the in-person mode (46.4% and 33.9%, respectively). Conclusions: Although it is initially more expensive to establish an eHealth service mode, the overall reoccurring costs per patient for delivery of best-practice weight management were lower compared to the in-person mode. This theoretical cost evaluation establishes preliminary evidence to support alternative obesity management service models using eHealth technologies. Further research is required to determine the feasibility, efficacy and cost-effectiveness of these models within dietetic practice.

Background: Better diets, as evaluated by diet quality indices, are associated with lower rates of morbidity and mortality. Although governments and researchers alike recognise the burden that obesity incurs for increased healthcare spending, there is insufficient evidence for the role of diet quality on healthcare costs. Methods: Diet quality was assessed by the Australian Recommended Food Score (ARFS) for 6328 women aged 50¿55 years from the Australian Longitudinal Study on Women's Health. The ARFS was ranked by quintile, and 10-year cumulative data on healthcare costs from Medicare (Australia's Universal healthcare cover) were reported by body mass index category, using generalised linear modelling. Results: Healthy weight women with the highest diet quality were found to make significantly fewer Medicare claims (P = 0.012) compared to those with the lowest diet quality. In healthy weight and overweight women, the number of healthcare claims and charges was inversely associated with consuming a greater variety of vegetables. For every 1 point increase in the ARFS vegetable component score, healthy weight women made 1.9 fewer healthcare claims and were charged $139 less, whereas overweight women made 2.3 fewer claims and were charged $176 less for healthcare over 10 years. Conclusions: The results of the present study support the need to prioritise an improved diet quality with the aim of reducing healthcare claims and overall costs in a population-based sample of Australian females. As the burden of overweight and obesity on the healthcare system increases, strategies to improve diet quality may be of particular importance; however, more research is required to further establish this relationship.

Objective To assess whether parent-reported time and cost for provision of food is associated with consumption of fruits, vegetables and non-core foods in pre-schoolers.Design Cross-sectional analysis of baseline data from the Healthy Habits randomised controlled trial. Two subscales of the Children's Dietary Questionnaire (CDQ) were used to assess fruit and vegetable, and non-core food consumption.Setting Thirty pre-schools in the Hunter Region of New South Wales, Australia.Subjects Parents (n 396) with a child aged 3-5 years attending a participating pre-school were recruited. Parents needed to reside with that child for at least four days per week and have primary responsibility for providing meals and snacks to their child.Results Sixty-three per cent of children had a parent-reported subscale score indicating adherence to dietary guidelines for fruit and vegetable intake, while 64% of children had a subscale score indicating they were exceeding dietary guidelines for non-core foods. Regression models revealed significant positive associations between higher CDQ scores for non-core foods (indicating higher consumption levels) and minutes that parents spent preparing food (P=0·032 and 0·025) and amount spent on purchasing food (P=0·043 and 0·020). The magnitude of the effects was small (estimate=0·003 and 0·001).Conclusions Time and cost spent by parents on provision of food was not significantly associated with child fruit and vegetable consumption. Further explorations into time spent on food preparation and cost of food procurement are warranted to help address the increased consumption of non-core foods by pre-school children.

Background: The present study systematically reviewed the literature aiming to determine the relationships between food addiction, as measured by the Yale Food Addiction Scale (YFAS), and mental health symptoms. Methods: Nine databases were searched using keywords. Studies were included if they reported: (i) YFAS diagnosis or symptom score and (ii) a mental health outcome, as well as the association between (i) and (ii). In total, 51 studies were included. Results: Through meta-analysis, the mean prevalence of food addiction diagnosis was 16.2%, with an average of 3.3 (range 2.85¿3.92) food addiction symptoms being reported. Subanalyses revealed that the mean number of food addiction symptoms in populations seeking treatment for weight loss was 3.01 (range 2.65¿3.37) and this was higher in groups with disordered eating (mean 5.2 3.6¿6.7). Significant positive correlations were found between food addiction and binge eating [mean r¿=¿0.602 (0.557¿0.643), P¿<¿0.05], depression, anxiety and food addiction [mean r¿=¿0.459 (0.358¿0.550), r¿=¿0.483 (0.228¿0.676), P¿<¿0.05, respectively]. Conclusions: A significant, positive relationship exists between food addiction and mental health symptoms, although the results of the present study highlight the complexity of this relationship.

Aim: Grandparents are assuming increased child-caregiving responsibilities, which potentially influences the dietary intake of grandchildren. The aim of this systematic review is to determine the influence of grandparental care on the dietary intake, food-related behaviours, food choices and weight status of their preschool and school-aged grandchildren. Methods: Six electronic health databases were searched in January 2017. Inclusion criteria were publication in English language, peer-reviewed journal between 2000 and 2017; children aged 2¿12 years; study outcomes included child dietary intake/weight status, grandparent nutrition knowledge/beliefs or grandparent/parent feeding practices. Included studies were appraised for quality and bias. The review was registered with PROSPERO, number CRD42016047518. Results: Sixteen studies were identified in the review, published between 2007 and 2016, with 15 assessed as moderate or high quality. Nine studies reported grandparental child feeding attitudes and behaviours that are considered to negatively influence child dietary intake, while three studies identified positive influences. Seven studies identified that differences in child feeding attitudes and behaviours between parents and grandparents created conflict and tensions between caregivers, often resulting in poor feeding practices. Statistically significant positive associations (odds ratio 1.47¿1.72) between grandparent cohabitation and increased rates of child overweight and obesity were found in four studies. Conclusions: Grandparents in caregiving roles may negatively influence the dietary intake and weight status of their grandchildren. More rigorous, targeted studies are required to further define the mechanisms by which grandparents' knowledge, attitudes and feeding behaviours may influence child dietary intake. This review suggests that grandparents may be an important audience to target in future child nutrition interventions.

Background: The majority of literature examining the effect of dietary behaviour on academic achievement has focused on breakfast consumption only. Here, we aim to systematically review the literature investigating the broader effects of dietary intake and behaviours on school-aged children's academic achievement. Methods: A search was undertaken across seven databases using keywords. For studies to be included, they needed to be conducted in: school-aged children (5¿18 years); assess and report: (i) a measure of academic performance; (ii) a measure of dietary intake/behaviour; and (iii) the association between dietary intake/behaviours and academic performance. Forty studies were included in the review. Results: The majority of studies were cross-sectional in design (n = 33) and studied children aged >10 years, with very few reports in younger age groups. More than 30 different dietary assessment tools were used, with only 40% of those using a validated/standardised assessment method. Half the studies collected outcomes of academic achievement objectively from a recognised educational authority, whereas 10 studies used self-reported measures. The dietary outcomes most commonly reported to have positive associations with academic achievement were: breakfast consumption (n = 12) and global diet quality/meal patterns (n = 7), whereas negative associations reported with junk/fast food (n = 9). Conclusions: This review highlights that moderate associations exist for dietary intakes characterised by regular breakfast consumption, lower intakes of energy-dense, nutrient-poor foods and overall diet quality with respect to outcomes of academic achievement. Future studies should consider the use of validated dietary assessment methods and standardised reporting of academic achievement.

Background Research investigating the effects of dietary behaviours on children's academic achievement has predominately focused on breakfast consumption. The aim of this study was to conduct secondary analysis to examine associations between a range of dietary behaviours and children's academic achievement. Methodology Data on five dietary variables (fruit intake; vegetable intake; consumption of takeaway; sugar sweetened beverages; and breakfast) and scores in the five domains of a standardised academic achievement test known as NAPLAN (reading, writing, grammar/punctuation, spelling and numeracy) were obtained for Australian children aged 8¿15 years in school grades three (n = 1185), five (n = 1147), seven (n = 1053) and nine (n = 860). Mixed linear models adjusted for socioeconomic status and gender were used to examine associations between dietary behaviours and academic scores. Results Greater consumption of vegetables with the evening meal (7 nights/week) was associated with higher test scores in the domains of spelling and writing (p=<0.01), with the greatest effect observed for spelling with a mean score difference of 86 ± 26.5 NAPLAN points between the highest and lowest levels of consumption (95% CI: 34.0¿138.1; p=<0.01). Increased consumption of sugar sweetened beverages was associated with significantly lower test scores in reading, writing, grammar/punctuation and numeracy (<0.01). Principle conclusions The findings of this study demonstrate dietary behaviours are associated with higher academic achievement. Future research should further explore relationships between a wide range of dietary behaviours and children's academic achievement.

Food addiction research in children is limited, and to date addictive-like eating behaviors within families have not been investigated. The aim of this study is to understand factors associated with addictive-like eating in children. The association between food addiction in children with obesity, parental food addiction, and parental feeding practices (i.e., restriction, pressure to eat, monitoring) was investigated. Parents/primary caregivers (aged¿=¿18¿years) of children aged 5¿12¿years, recruited and completed an online cross-sectional survey including demographics, the Yale Food Addiction Scale (YFAS), and the Child Feeding Questionnaire (CFQ). Parents, reporting on themselves and one of their children, were given a food addiction diagnosis and symptom score according to the YFAS predefined criteria. The total sample consisted of 150 parents/primary caregivers (48% male) and 150 children (51% male). Food addiction was found to be 12.0% in parents and 22.7% in children. In children, food addiction was significantly associated with higher child BMI z-scores. Children with higher food addiction symptoms had parents with higher food addiction scores. Parents of FA children reported significantly higher levels of Restriction and Pressure to eat feeding practices, but not Monitoring. Children with elevated YFAS-C scores may be at greater risk for eating-related issues.

Objective: CVD is a leading cause of mortality and morbidity, and nutrition is an important lifestyle factor. The aim of the present systematic review was to synthesise the literature relating to knowledge translation (KT) of dietary evidence for the prevention and treatment of CVD into practice in populations with or at high risk of CVD. Design: A systematic search of six electronic databases (CINAHL, Cochrane, EMBASE, MEDLINE, PsycINFO and Scopus) was performed. Studies were included if a nutrition or dietary KT was demonstrated to occur with a relevant separate measureable outcome. Quality was assessed using a tool adapted from two quality checklists. Subjects: Population with or at high risk of CVD or clinicians likely to treat this population. Results: A total of 4420 titles and abstracts were screened for inclusion, with 354 full texts retrieved to assess inclusion. Forty-three articles were included in the review, relating to thirty-five separate studies. No studies specifically stated their aim to be KT. Thirty-one studies were in patient or high-risk populations and four targeted health professionals. Few studies stated a theory on which the intervention was based (n 10) and provision of instruction was the most common behaviour change strategy used (n 26). Conclusions: KT in nutrition and dietary studies has been inferred, not stated, with few details provided regarding how dietary knowledge is translated to the end user. This presents challenges for implementation by clinicians and policy and decision makers. Consequently a need exists to improve the quality of publications in this area.

Purpose of Review: Behavioural and neurobiological similarities have been identified between the consumption of certain foods and addiction-related disorders. However, few studies have investigated what components of food may promote an addictive-like response in humans. This review evaluates recent research concerning the nutritional aspects of addictive-like eating. Recent Findings: Based on the current evidence base, highly processed, hyper-palatable foods with combinations of fat and sugar appear most likely to facilitate an addictive-like response. Total fat content and glycaemic index also appear to be important factors in the addictive potential of foods. Despite public interest and evidence from animal studies, few studies have reported an association between sugar and addictive-like eating. Summary: Due to the paucity of studies, it is difficult to conclusively identify a specific food or ingredient as capable of triggering an addictive-like response in humans. Future studies using validated dietary assessment tools are essential and may inform the development of novel strategies to treat maladaptive eating behaviours.

Background: Short food questions are appealing to measure dietary intakes. Methods: A review of studies published between 2004 and 2016 was undertaken and these were included in the present study if they reported on a question or short item questionnaire (=50 items, data presented as =30 food groups) measuring food intake or food-related habits, in children (aged 6¿months to 18¿years), and reported question validity or reliability. Thirty studies met the inclusion criteria. Results: Most questions assessed foods or food groups (n¿=¿29), with the most commonly assessed being fruit (n¿=¿22) or vegetable intake (n¿=¿23), dairy foods and discretionary foods (n¿=¿20 studies each). Four studies assessed food habits, with the most common being breakfast and meal frequency (n¿=¿4 studies). Twenty studies assessed reliability, and 25 studies determined accuracy and were most commonly compared against food records. Evaluation of question performance relied on statistical tests such as correlation. Conclusions: The present study has identified valid and reliable questions for the range of key food groups of interest to public health nutrition. Questions were more likely to be reliable than accurate, and relatively few questions were both reliable and accurate. Gaps in repeatable and valid short food questions have been identified that will provide direction for future tool development.

Aim: The aim was to evaluate the utility of a brief dietary intake assessment tool in measuring nutritional adequacy of preschoolers and differences in food and nutrient intake between quartiles stratified by overall diet quality. Methods: Dietary intakes of preschoolers (n = 146) from the Feeding Healthy Food to Kids trial were reported by parents/caregivers using a 120-item food frequency questionnaire (FFQ). Diet quality was assessed using the Australian Recommended Food Score for Preschoolers. Analyses were performed using Kruskal¿Wallis one-way analysis of variance, adjusted for Type 1 error. Participants were grouped into quartiles by total food score for comparison of subscale scores, food groups and nutrient intakes from the FFQ. Results: Participants who scored less than the median total food score of 36 were more likely to have suboptimal micronutrient intakes. Median fruit (9 vs 5, P < 0.0001) and vegetable (14 vs 7, P < 0.0001) subscale scores for preschoolers in the highest quartile were significantly higher than the lowest quartile, indicating much greater fruit and vegetable variety. Statistically significant differences in diet quality score by quartiles (P < 0.05) were found for total energy and percentage energy from core foods, protein, fibre and 11 micronutrients. Conclusions: The Australian Recommended Food Score for Preschoolers is a practical brief diet quality assessment tool to measure food variety and nutritional adequacy in Australian preschoolers. Stratifying children by baseline diet quality in future nutrition interventions is recommended in order to identify those who are likely to benefit or require more targeted approaches to address specific nutritional needs in order to optimise food and nutrient intakes.

© 2016 The British Dietetic Association Ltd. Background: The present study aimed to evaluate core food intakes in 9¿10-year-old Australian children by considering adequacy of nutrient intakes, comparing servings of core food groups with Australian recommendations and scoring overall diet quality. Methods: Children from an established community-based cohort study completed a semi-quantitative food frequency questionnaire. Daily intakes of energy, macronutrients, micronutrients, servings of core (i.e. nutrient-rich) foods and a diet quality index were calculated and compared with appropriate standards. Sex and socio-economic differences were examined. Results: The 436 children participating were from low to high socio-economic status families. As a group, over half of the children met estimated average requirements for key macro- and micronutrients, with the exception of fibre (inadequate in 41% of boys and 24% of girls). Children obtained 55% of their daily energy from core foods. Most children had fewer than the recommended servings of vegetables (91%) and meat/alternatives (99.8%), whereas boys generally ate fewer servings of grains and cereals than recommended (87%), and girls ate fewer servings of dairy (83%). Diet quality scores indicated room for improvement (median score of 26 for boys and 25 for girls, out of a maximum of 73 points). Conclusions: As a group, a large proportion of children were able to meet their daily nutrient requirements. However, achieving this through noncore foods meant that diets were high in salt, saturated fat and sugar; more servings of core foods and greater dietary diversity would be preferable. These results suggest that families need more support to optimise dietary patterns of children in this age group.

Background Consumption of dietary carotenoids from fruits and vegetables (F/V) leads to accumulations in human skin, altering skin yellowness. The influence of the quantity of F/V consumed on skin yellowness and plasma carotenoid concentrations has not been examined previously. Objective To compare the influence of consuming high-carotenoid-containing F/V (HCFV) (176,425 µg beta carotene/wk) vs low-carotenoid F/V (LCFV) (2,073 µg beta carotene/wk) on skin yellowness and plasma carotenoid concentrations, over 4 weeks. Design and intervention A single-blind randomized controlled crossover trial from October 2013 to March 2014. Thirty women were randomized to receive 7 daily servings of HCFV or LCFV for 4 weeks. Following a 2-week washout period they followed the alternate intervention. Main outcome measures Skin color (Commission Internationale de l'Eclairage L*a*b* color space, where L* represents skin lightness and positive values of a* and b* represent degrees of redness and yellowness, respectively) was assessed by reflectance spectroscopy in both sun-exposed and nonexposed skin areas. Fasting plasma carotenoids were determined by high-performance liquid chromatography, before and after each intervention period. Statistical analyses performed Linear mixed models were used to determine the HCFV and LCFV response on skin color and plasma carotenoids, adjusting for intervention order, time, and interaction between baseline differences and time. Results There were no significant differences in mean daily fruit (P=0.42) and vegetable (P=0.17) intakes between HCFV and LCFV groups. Dietary alpha carotene, beta carotene, lutein, and beta cryptoxanthin intakes were significantly different between the two groups (P<0.01). Following HCFV there was a significantly greater increase in skin yellowness (b*) in both sun-exposed (P<0.001) and unexposed areas, (P<0.001), with no change in skin lightness (L*) or redness (a*). Significantly higher plasma alpha carotene (P=0.004), beta carotene (P=0.001), and lutein (P=0.028) concentrations were found following the HCFV intervention. Skin yellowness correlated with alpha carotene and beta carotene. Conclusions Skin yellowness (b*) and fasting plasma carotenoid concentrations were significantly higher following HCFV than LCFV over 4 weeks.

Objectives: There is increasing interest in the role of addictive-like eating in weight gain. No studies have investigated associations between addictive-like eating and specific patterns of fat deposition which are sensitive indicators of chronic disease risk. This exploratory study aimed to evaluate relationships between Yale Food Addiction Scale (YFAS) assessed "food addiction" and visceral adiposity. Methods: Australian adults aged 18-35 years were recruited to an online survey including demographics and the YFAS. The YFAS is a 25-item tool designed to assess addictive-like eating behaviors and uses two scoring outputs, "diagnosis" and "symptom scores". Participants had their anthropometric measurements taken [height, weight and body composition (visceral fat, fat mass, percentage body fat)] using a standardized protocol. Results: Ninety-three female participants (age 24.3 ± 4.0years, BMI 24.3 ± 6.0 kg/m2) completed all measurements. Twenty-one participants (22.3%) met the predefined criteria for YFAS "diagnosis". YFAS "symptom scores" were moderately correlated with visceral fat area (r = 0.36, p < 0.001), and "symptom scores" predicted increases in visceral fat area [r2 = 0.17, ß = 1.17, p = 0.001]. Effect sizes were moderate for all variables. Conclusion: This study showed that YFAS assessed FA was associated with visceral fat deposition, a sensitive indicator of increased cardiometabolic risk. Future research is required to investigate whether FA predicts future weight gain.

© 2016 The British Dietetic Association Ltd. Background: Childhood obesity is becoming more common as Malaysia experiences rapid nutrition transition. Current evidence related to parental influences on child dietary intake and body weight status is limited. The present study aimed to report, among Malay families, the prevalence of energy mis-reporting and dietary relationships within family dyads. Methods: The cross-sectional Family Diet Study (n = 236) was conducted at five primary schools in central of Peninsular Malaysia. Each family consisted of a Malay child, aged 8¿12 years, and their main caregiver(s). Information on socio-demographics, dietary intake and anthropometry were collected. Correlations and regression analyses were used to assess dietary relationships within family dyads. Results: Approximately 29.6% of the children and 75.0% parents were categorised as being overweight or obese. Intakes of nutrients and food groups were below the national recommended targets for majority of children and adults. A large proportion of energy intake mis-reporters were identified: mothers (55.5%), fathers (40.2%) and children (40.2%). Children's body mass index (BMI) was positively associated with parental BMI (fathers, r = 0.37; mothers, r = 0.34; P < 0.01). For dietary intakes, moderate-to-strong (0.35¿0.72) and weak-to-moderate (0.16¿0.35) correlations were found between mother¿father and child¿parent dyads, respectively. Multiple regression revealed that maternal percentage energy from fat (ß = 0.09, P < 0.01) explained 81% of the variation in children's fat intake. Conclusions: Clear parental dietary relationships, especially child¿mother dyads, were found. Despite a significant proportion of families with members who were overweight or obese, the majority reported dietary intakes below recommended levels, distorted by energy mis-reporting. The findings of the present study can inform interventions targeting parent¿child relationships to improve family dietary patterns in Malaysia.

Background/Objectives:Limited dietary intake tools have been validated specifically for hyperlipidaemic adults. The Australian Eating Survey (AES) Food Frequency Questionnaire (FFQ) was adapted to include foods with cardio-protective properties (CVD-AES). The aims were to estimate dietary fatty acid (FA) intakes derived from the CVD-AES and AES and compare them with red blood cell (RBC) membrane FA content.Subjects/Methods:Dietary intake was measured using the semi-quantitative 120-item AES and 177-item CVD-AES. Nutrient intakes were calculated using AUSNUT 2011-2013. Fasting RBC membrane FAs were assessed using gas chromatography. Extent of agreement between intakes estimated by AES or CVD-AES and RBC membrane composition (% of total FAs) for linoleic acid (LA), alpha-linolenic acid (ALA), eicosapentanoic acid (EPA), docosapentaenoic acid (DPA) and docosahexaenoic acid (DHA) were assessed using Spearman's correlation coefficients, adjusted linear regressions and Kappa statistics.Results:Data from 39 participants (72% female, 59.3±11.1 years) indicate stronger positive correlations between RBC membrane FAs and CVD-AES dietary estimates compared with the AES. Significant (P<0.05) moderate-strong correlations were found between CVD-AES FAs and FA proportions in RBC membranes for EPA (r=0.62), DHA (r=0.53) and DPA (r=0.42), with a moderate correlation for LA (r=0.39) and no correlation with ALA. Significant moderate correlations were found with the AES for DHA (r=0.39), but not for LA, ALA, EPA or DPA.Conclusions:The CVD-AES provides a more accurate estimate of long chain FA intakes in hyperlipidaemic adults, compared with AES estimates. This indicates that a CVD-specific FFQ should be used when evaluating FA intakes in this population.

The Yale Food Addiction Scale (YFAS) is a widely used tool to assess the behavioural indicators of addictive-like eating. No studies, however, have used a longitudinal design to determine whether these addictive-like eating behaviours are a stable or transient phenomenon in a community-based population. This study aimed to evaluate whether food addiction Diagnosis and Symptom scores as assessed by the YFAS remain stable over 18-months in a non-clinical population. Young adults aged 18-35 years were recruited from the community to a web-based survey in 2013. The survey included demographics, anthropometrics and the YFAS. Participants who volunteered to be recontacted for future research were invited to complete the same survey 18-months later. The YFAS scoring outputs Diagnosis and Symptom scores were tested for agreement and reliability between the two time points. Of the 303 participants who completed the original survey and agreed to be recontacted, 69 participants (22.8% of those recontacted, 94% female, 67% normal weight at baseline) completed the 18-month follow-up survey. At baseline, thirteen participants met the YFAS predefined criteria for Diagnosis, while eleven participants met these criteria at the 18-month follow-up. YFAS Diagnosis was found to have moderate agreement [K = .50, 95% CI (.23, .77)] between the two time points while Symptom scores had good agreement [K = .70, 95% CI (.54, .83)]. Intraclass correlation coefficients were interpreted as moderate over the 18-month period for both the Diagnosis [ICC = .71, 95% CI (.45, .88)] and Symptom scores [ICC = .72, 95% CI (.58, .82)]. YFAS assessed food addiction Diagnosis and Symptom scores were found to be relatively stable over 18-months in a non-clinical population of predominantly female, young adults. Future research is required to determine the impact of behavioural weight loss interventions on YFAS assessed addictive-like eating.

Aim: To compare dietary intakes of young children to the Australian Guide to Healthy Eating (AGHE) and Nutrient Reference Values (NRVs). Methods: Dietary intakes of 54 children (50% girls) aged two to three years (mean 2.7 years) from the Women and Their Children's Health (WATCH) study were reported by mothers using a validated 120-item food frequency questionnaire. Daily consumption of AGHE food group servings, macronutrients, and micronutrients were compared to the AGHE and NRVs using t-test with significance set at P < 0.05. Results: No child achieved all AGHE targets, with the majority consuming less breads/cereals (1.9 vs 4.0 servings/day), vegetables (1.3 vs 2.5), and meat/alternatives (0.7 vs 1.0), all P < 0.0001. Adequate servings were observed for dairy (2.2 vs 1.5) and fruit (1.3 vs 1.0). Macronutrients were within recommended ranges, although 96% exceeded saturated fatty acid recommendations. Children who met selected NRVs consumed more fruit (1.4 vs 1.0; P < 0.0086), dairy (2.2 vs 1.5; P < 0.0001) and discretionary foods (2.6 vs =1.0; P < 0.0001) but less breads/cereals (2.0 vs 4.0; P < 0.0001) and vegetables (1.3 vs 2.5; P < 0.0001) servings, compared to the AGHE recommended servings. Conclusions: Child dietary intakes did not align with AGHE, while adequate nutrient profiles were achieved by various dietary patterns. Future studies involving data from larger, representative samples of children are warranted.

Background: Evidence has suggested that omega-3 (n-3) polyunsaturated fatty acids (PUFAs) improve obesity-induced insulin resistance (IR); however, results from human intervention trials have been equivocal. Recently it has been reported that n-3 PUFA status is inversely associated with type 2 diabetes in women but not in men, suggesting a sex-dependent effect. Objective: We aimed to determine whether n-3 PUFA interventions affect IR in a sex-dependent manner. Design: Five databases were searched (Medline, EMBASE, CINAHL, Scopus, and Pre-Medline) for randomized controlled trials. Searches were limited to the English language and to studies with adults aged .18 y. When possible, studies were pooled for a meta-analysis. The principle summary measure was the standardized mean difference (SMD) between groups. Results: Thirty-one eligible trials were identified with a total of 1848 participants [men: 45.1%; weighted mean 6 SD age: 52.5 6 8.2 y; weighted body mass index (in kg/m2): 28.8 6 3.0]. Seven studies were conducted in women, 4 studies were conducted in men, and the remaining studies pooled men and women together. Twenty-six trials were pooled for the meta-analysis (men: n = 2; women: n = 6). With all studies (n = 26) pooled, there was no effect of n-3 PUFA on IR at the group level (SMD: 0.089; 95% CI: 20.105, 0.283; P = 0.367). In trials of 6 wk, a significant improvement in IR was seen in women (SMD: 20.266; 95% CI: 20.524, 20.007; P = 0.045) but not in men (SMD: 0.619; 95% CI: 20.583, 1.820; P = 0.313). Conclusions: With this analysis, we provide preliminary evidence of a sex-dependent response of IR to an n-3 PUFA intervention. Additional studies are needed to confirm sex-dependent associations and to elucidate the potential mechanisms that are involved.

Issues addressed It is not known whether individuals can accurately estimate the portion size of foods usually consumed relative to standard serving sizes in national food selection guides. The aim of the present cross-sectional pilot study was to quantify what adults and children deem a typical portion for a variety of foods and compare these with the serving sizes specified in the Australian Guide to Healthy Eating (AGHE). Methods Adults and children were independently asked to serve out their typical portion of 10 common foods (rice, pasta, breakfast cereal, chocolate, confectionary, ice cream, meat, vegetables, soft drink and milk). They were also asked to serve what they perceived a small, medium and large portion of each food to be. Each portion was weighed and recorded by an assessor and compared with the standard AGHE serving sizes. Results Twenty-one individuals (nine mothers, one father, 11 children) participated in the study. There was a large degree of variability in portion sizes measured out by both parents and children, with means exceeding the standard AGHE serving size for all items, except for soft drink and milk, where mean portion sizes were less than the AGHE serving size. The greatest mean overestimations were for pasta (155%; mean 116 g; range 94-139g) and chocolate (151%; mean 38 g; range 25-50g), each of which represented approximately 1.5 standard AGHE servings. Conclusion The findings of the present study indicate that there is variability between parents' and children's estimation of typical portion sizes compared with national recommendations. So what? Dietary interventions to improve individuals' dietary patterns should target education regarding portion size.

With the growth of Internet technologies, offering interventions for child and family weight management in an online format may address barriers to accessing services. This study aimed to investigate (i) whether an eHealth family healthy lifestyle program would be of interest to parents; and (ii) preferences and/or expectations for program components and features. Parents of children aged four to18 years were recruited through social media and completed an online survey (54 items) including closed and open-ended questions. Responses were collated using descriptive statistics and thematic analysis. Seventy-five participants were included (92% mothers, mean age 39.1 ± 8.6 years, mean BMI 27.6 ± 6.3 kg/m2). The index child had a mean age of 11 ± 6.2 years with 24% overweight/obese. The majority of parents (90.3%) reported interest in an online program, with preference expressed for a non-structured program to allow flexibility users to log-on and off as desired. Parents wanted a program that was easy to use, practical, engaging, endorsed by a reputable source, and able to provide individual tailoring and for their children to be directly involved. The current study supports the need for online delivery of a healthy lifestyle program that targets greater parental concerns of diet rather than child weight.

© 2015 Dietitians Association of Australia. Aims: There is increasing interest in the use of smartphone applications (apps) for delivering child obesity management interventions and supporting lifestyle behaviour change; however, there has been very little academic research on their development. Our aim is to review nutrition-related apps designed for children currently available in Australia for their usefulness in education or support behavioural interventions for child obesity. Methods: Apps available for download in iTunes Australia between 2 April and 3 June 2013 which were suitable for children >12 years were identified. Key words were chosen to identify apps applicable to children, focusing on nutrition. Results: A total of 27 apps were included. Most apps (24/27) were not based on evidence-informed recommendations. A third of apps were developed in the USA (n = 10; 37%) and were free (67%), nine apps required upfront payment, with a mean cost of $A2.80 (range $A0.99-$A7.49). The most common nutrition features were the promotion of energy balance (n = 12 apps) and guidance on appropriate portion size (n = 15). The most common behaviour change feature was goal setting (n = 15). The five apps that scored most highly against the characteristics reviewed were: Calorie Counter Pro by My Net Diary, Weight Watchers, Swap It Don't Stop It, Control My Weight by CalorieKing and Rate What I Ate-Photo Diet Tracker. Conclusions: Very few apps were identified that could be used in education or support behavioural interventions for child obesity. There is a need to harness this technology and evaluate the applicability and use within childhood obesity research interventions.

Purpose: Few efficacious child obesity interventions have been converted into ongoing community programs in the after-school setting. The aim of this study was to evaluate the impact of phase 2 of the Back to Basics cooking club on dietary behaviours and fruit and vegetable variety in a population at risk of obesity at a low income school with > 10% indigenous population. Methods: Baseline and 3-month dietary intake and social cognitive theory (SCT) constructs were collected in 51 children, mean age 9 years, 61% female. McNemar tests were used for comparison of proportions between categorical variables. Cohen's d was used to compare effect sizes across different measures. Results: Consumption of one or more fruit servings per day significantly increased from 41% to 67% (P = 0.02, d = 0.13) and there was a trend for increasing the weekly variety of fruit and vegetables. The SCT constructs assessed within the current study improved significantly (P < 0.05), with moderate to large effect sizes (d = 0.33-0.78). Conclusion: This study documents that a previous efficacious healthy lifestyle program can be adapted for use as an obesity prevention program addressing improvements in vegetable and fruit intakes in a low income community with a relatively high indigenous population.

Background: Being overweight and obese in Australian children is common. Current evidence related to parental influence on child dietary intake is conflicting, and is particularly limited in terms of which parent exerts the stronger relationship. The present study aimed to assess mother-father and parent-child dietary relationships and to identify which parent-child relationship is stronger. Methods: A cross-sectional analysis was performed of dietary intake data from 66 families with one parent and one child aged 8-12 years who were participating in the Family Diet Quality Study, in the Hunter and Forster regions of New South Wales, Australia. Dietary intakes were assessed using adult and child specific, validated semi-quantitative 120-item food frequency questionnaires. Diet quality and variety subscores were assessed using the Australian Recommended Food Scores for adults and children/adolescents. Pearson's correlations were used to assess dietary relationships between mother-father, father-child and mother-child dyads. Results: Weak-to-moderate correlations were found between mother-child dyads for components of dietary intake (r = 0.27-0.47). Similarly, for father-child dyads, predominantly weak-to-moderate correlations were found (r = 0.01-0.52). Variety of fruit intake was the most strongly correlated in both parent-child dyads, with the weakest relationships found for fibre (g 1000 kJ-1) in father-child and percentage energy from total fats for mother-child dyads. Mother-father dyads demonstrated mostly moderate-to-strong correlations (r = 0.13-0.73), with scores for condiments showing the weakest relationship and vegetables the strongest. For all dyads, strong correlations were observed for overall diet quality (r = 0.50-0.59). Conclusions: Parent-child dietary intake is significantly related but differs for mother versus fathers. Further research is required to examine whether differing dietary components should be targeted for mothers versus fathers in interventions aiming to improve family dietary patterns.

Introduction: The contribution of the family environment to childhood obesity in Malaysia is not well known. This paper describes the study, methodology and results of a pilot study to assess the feasibility of conducting a study on diet and lifestyle factors among Malay primary school children and their main caregiver(s) in regard to body weight status. Methods: The Family Diet Study used a crosssectional design and targeted a minimum of 200 Malay families at five national primary schools in the Klang Valley, Malaysia using a multi-stage sampling method. Participants were Malay families with children aged 8 to 12 years and their main caregiver(s). Data on socio-demographic, dietary intake, parental child feeding practices, physical activity and anthropometric measures were collected predominantly at schools with follow-up 24-h dietary recalls collected by phone. Details of recruitment, inclusion criteria, assessments and statistical analyses are also discussed. Results: Eleven families provided data by answering questionnaires, recalling diet intake and participating in anthropometric measures. The results showed overall feasibility of the study protocol but required some modifications prior to implementation of the main study. Mothers were the main parent involved in family food procurement, preparation and mealtime supervision. Snacking was not commonly reported and fruit and vegetables intakes were generally infrequent. Conclusion: The most novel component of this study was the comprehensive collection of data from both children and their main caregiver(s) within the context of the family. Detailed information on dietary and lifestyle aspects will help to elucidate factors associated with obesity aetiology in Malay children.

BackgroundIt has been suggested that addictive behaviors related to consumption of specific foods could contribute to overeating and obesity. Although energy-dense, hyper-palatable foods are hypothesized to be associated with addictive-like eating behaviors, few studies have assessed this in humans. ObjectiveTo evaluate in young adults whether intakes of specific foods are associated with 'food addiction', as assessed by the Yale Food Addiction Scale (YFAS), and to describe the associated nutrient intake profiles. DesignAustralian adults aged 18-35. years were invited to complete an online cross-sectional survey including demographics, the YFAS and usual dietary intake. Participants were classified as food addicted (FAD) or non-addicted (NFA) according to the YFAS predefined scoring criteria. ResultsA total 462 participants (86% female, 73% normal weight) completed the survey, with 14.7% (n = 68) classified as FAD. The FAD group had a higher proportion of females (p =. 01) and higher body mass index (p< .001) compared to NFA. Higher YFAS symptom scores were associated with higher percentage energy intake (%E) from energy-dense, nutrient-poor foods including candy, take out and baked sweet products, as well as lower %E from nutrient-dense core foods including whole-grain products and breakfast cereals. These remained statistically significant when adjusted for age, sex and BMI category (p = .001). ConclusionsStatistically significant associations were identified between YFAS assessed food addiction and dietary intake, specifically intakes of energy-dense, nutrient-poor foods. However, the effect sizes were small limiting clinical applications. Further examination of the relationship between addictive-like eating and intake of specific foods in a nationally representative sample is warranted.

Background Previous research has demonstrated that plasma carotenoids are a reliable biomarker of usual fruit and vegetable intake. The review aims were to synthesize (i) the mean dietary intake and (ii) plasma concentrations of carotenoids reported from validation studies (iii) compare the strength of the relationship between the two, measured using different dietary assessment methods. Methods Six databases were used to locate studies that included: adult populations, assessment of dietary intake, measurement of plasma carotenoids and reported the comparison between the two measures. Results One hundred and forty-two studies were included with 95,480 participants, the majority of studies were cross-sectional (n = 86), with randomized controlled trials (RCTs) (n = 18), 14 case-control studies and 13 cohorts. The most common reported dietary carotenoid and plasma carotenoid was lycopene: weighted dietary mean intake (4555.4 ug/day), and plasma concentration 0.62 umol/L (95% CI: 0.61, 0.63, n = 56studies. The strongest weighted correlation between the two measures was found for cryptoxanthin (r = 0.38, 95% CI 0.34, 0.42) followed by a-carotene (r = 0.34, 95% CI 0.31, 0.37). Conclusion This review summarizes typical dietary intakes and plasma concentrations and their expected associations based on validation studies conducted to date which provides a benchmark for future validation studies.

Background: Physical activity and consuming a healthy diet have clear benefits to the physical and psychosocial health of cancer survivors, with guidelines recognising the importance of these behaviors for cancer survivors. Interventions to promote physical activity and improve dietary behaviors among cancer survivors and carers are needed. The aim of this study was to determine the effects of a group-based, face-to-face multiple health behavior change intervention on behavioral outcomes among cancer survivors of mixed diagnoses and carers. Methods: The Exercise and Nutrition Routine Improving Cancer Health (ENRICH) intervention was evaluated using a two-group pragmatic randomized controlled trial. Cancer survivors and carers (n=174) were randomly allocated to the face-to-face, group-based intervention (six, theory-based two-hour sessions delivered over 8weeks targeting healthy eating and physical activity [PA]) or wait-list control (after completion of 20-week data collection). Assessment of the primary outcome (pedometer-assessed mean daily step counts) and secondary outcomes (diet and alcohol intake [Food Frequency Questionnaire], self-reported PA, weight, body mass index, and waist circumference) were assessed at baseline, 8-and 20-weeks. Results: There was a significant difference between the change over time in the intervention group and the control group. At 20weeks, the intervention group had increased by 478 steps, and the control group had decreased by 1282 steps; this represented an adjusted mean difference of 1761 steps (184 to 3337; P=0.0028). Significant intervention effects for secondary outcomes, included a half serving increase in vegetable intake (difference 39g/day; 95% CI: 12 to 67; P=0.02), weight loss (kg) (difference -1.5kg; 95% CI, -2.6 to -0.3; P=0.014) and change in body mass index (kg/m2) (difference -0.55kg/m2; 95% CI, -0.97 to -0.13; P=0.012). No significant intervention effects were found for self-reported PA, total sitting time, waist circumference, fruit, energy, fibre, alcohol, meat, or fat consumption. Conclusions: The ENRICH intervention was effective for improving PA, weight, body mass index, and vegetable consumption even with the inclusion of multiple cancer types and carers. As an example of successful research translation, the Cancer Council NSW has subsequently adopted ENRICH as a state-wide program.

Obesity is a global issue and it has been suggested that an addiction to certain foods could be a factor contributing to overeating and subsequent obesity. Only one tool, the Yale Food Addiction Scale (YFAS) has been developed to specifically assess food addiction. This review aimed to determine the prevalence of food addiction diagnosis and symptom scores, as assessed by the YFAS. Published studies to July 2014 were included if they reported the YFAS diagnosis or symptom score and were published in the English language. Twenty-five studies were identified including a total of 196,211 predominantly female, overweight/obese participants (60%). Using meta-analysis, the weighted mean prevalence of YFAS food addiction diagnosis was 19.9%. Food addiction (FA) diagnosis was found to be higher in adults aged >35 years, females, and overweight/obese participants. Additionally, YFAS diagnosis and symptom score was higher in clinical samples compared to non-clinical counterparts. YFAS outcomes were related to a range of other eating behavior measures and anthropometrics. Further research is required to explore YFAS outcomes across a broader spectrum of ages, other types of eating disorders and in conjunction with weight loss interventions to confirm the efficacy of the tool to assess for the presence of FA.

Background: Diet quality tools provide researchers with brief methods to assess the nutrient adequacy of usual dietary intake. This study describes the development and validation of a pediatric diet quality index, the Australian Recommended Food Scores for Pre-schoolers (ARFS-P), for use with children aged two to five years. Methods. The ARFS-P was derived from a 120-item food frequency questionnaire, with eight sub-scales, and was scored from zero to 73. Linear regressions were used to estimate the relationship between diet quality score and nutrient intakes, in 142 children (mean age 4 years) in rural localities in New South Wales, Australia. Results: Total ARFS-P and component scores were highly related to dietary intake of the majority of macronutrients and micronutrients including protein, ß-carotene, vitamin C, vitamin A. Total ARFS-P was also positively related to total consumption of nutrient dense foods, such as fruits and vegetables, and negatively related to total consumption of discretionary choices, such as sugar sweetened drinks and packaged snacks. Conclusion: ARFS-P is a valid measure that can be used to characterise nutrient intakes for children aged two to five years. Further research could assess the utility of the ARFS-P for monitoring of usual dietary intake over time or as part of clinical management.

The present systematic review examined the effectiveness of weight management interventions comparing diets with varying macronutrient distributions on BMI and cardiometabolic risk factors in overweight or obese children and adolescents. A systematic search of seven databases for the period 1975-2013 identified 14 eligible randomized or quasi-randomized controlled trials conducted with 6-18-year-old subjects. Seven trials compared a low-fat (=33% energy or <40g/day) to an isocaloric (n=2) or ad libitum (n=5) low-carbohydrate diet (<20% energy or <60g/day). Meta-analysis indicated a greater reduction in BMI in the low-carbohydrate group immediately after dietary intervention; however, the quality of the studies was limited and cardiometabolic benefits were inconsistent. Six trials compared increased-protein diets (19-30% energy) to isocaloric standard-protein diets (15-20% energy) and one compared an increased-fat diet (40% energy) to an isocaloric standard-fat diet (27% energy); there were no differences in outcomes in these studies. Current evidence suggests that improved weight status can be achieved in overweight or obese children and adolescents irrespective of the macronutrient distribution of a reduced-energy diet. Tailoring the macronutrient content to target specific cardiometabolic risk factors, such as a low-carbohydrate diet to treat insulin resistance, may be possible, but further research is needed before specific recommendations can be made. © 2014 International Life Sciences Institute.

Objective: To evaluate the effectiveness of the 'Healthy Dads, Healthy Kids (HDHK)' program when delivered by trained facilitators in community settings. Method: A two-arm randomized controlled trial of 93 overweight/obese fathers (mean [SD] age=40.3 [5.3] years; BMI=32.5 [3.8] kg/m2) and their primary school-aged children (n=132) from the Hunter Region, Australia. In 2010-2011, families were randomized to either: (i) HDHK intervention (n=48 fathers, n=72 children) or (ii) wait-list control group. The 7-week intervention included seven sessions and resources (booklets, pedometers). Assessments were held at baseline and 14-weeks with fathers' weight (kg) as the primary outcome. Secondary outcomes for fathers and children included waist, BMI, blood pressure, resting heart rate, physical activity (pedometry), and self-reported dietary intake and sedentary behaviors. Results: Linear mixed models (intention-to-treat) revealed significant between-group differences for fathers' weight (P < .001, d= 0.24), with HDHK fathers losing more weight (- 3.3. kg; 95%CI, - 4.3, - 2.4) than control fathers (0.1. kg; 95%CI, - 0.9,1.0). Significant treatment effects (P < .05) were also found for fathers' waist (d= 0.41), BMI (d= 0.26), resting heart rate (d= 0.59), energy intake (d= 0.49) and physical activity (d= 0.46) and for children's physical activity (d= 0.50) and adiposity (d= 0.07). Discussion: HDHK significantly improved health outcomes and behaviors in fathers and children, providing evidence for program effectiveness when delivered in a community setting. © 2014 Published by Elsevier Inc.

Background: Food frequency questionnaires (FFQ) are used in epidemiological studies to investigate the relationship between diet and disease. There is a need for a valid and reliable adult FFQ with a contemporary food list in Australia. Aims: To evaluate the reproducibility and comparative validity of the Australian Eating Survey (AES) FFQ in adults compared to weighed food records (WFRs). Methods: Two rounds of AES and three-day WFRs were conducted in 97 adults (31 males, median age and BMI for males of 44.9 years, 26.2 kg/m2, females 41.3 years, 24.0 kg/m2. Reproducibility was assessed over six months using Wilcoxon signed-rank tests and comparative validity was assessed by intraclass correlation coefficients (ICC) estimated by fitting a mixed effects model for each nutrient to account for age, sex and BMI to allow estimation of between and within person variance. Results: Reproducibility was found to be good for both WFR and FFQ since there were no significant differences between round 1 and 2 administrations. For comparative validity, FFQ ICCs were at least as large as those for WFR. The ICC of the WFR-FFQ difference for total energy intake was 0.6 (95% CI 0.43, 0.77) and the median ICC for all nutrients was 0.47, with all ICCs between 0.15 (%E from saturated fat) and 0.7 (g/day sugars). Conclusions: Compared to WFR the AES FFQ is suitable for reliably estimating the dietary intakes of Australian adults across a wide range of nutrients. © 2013 Elsevier Ltd and European Society for Clinical Nutrition and Metabolism.

Background: Diet quality indices add an important dimension to dietary assessment. The aim of this systematic review was to: (i) identify and describe the attributes and applications of diet quality indices developed for use or used in paediatric populations; (ii) describe associations between these diet quality indices and health-related variables in paediatric populations; and (iii) identify factors that are associated with diet quality in paediatric populations worldwide. Methods: Studies were identified by searching electronic databases for relevant papers from 1980 to October 2013 using keywords. Inclusion criteria were original studies that utilised a quantitative measure of diet quality in children and adolescents aged 0-18 years. Results: One hundred and nineteen studies met the inclusion criteria, from which 80 different diet quality indices were identified. The majority of studies had >1000 participants and were of acceptable quality. Of the 56 studies that investigated health-related outcomes, weight status was the most researched. Europe produced the most number of diet quality indices (n = 27 indices). Of the 119 studies, seven intervention studies were identified. Paediatric diet quality indices were found to be associated with environmental, behavioural and maternal factors. Conclusions: The use of diet quality indices in paediatric populations is a rapidly expanding area of research in diverse populations internationally. In economically disadvantaged countries, diet quality indices may be predictive of child growth. However, prospective cohort, intervention and validation studies are required to draw stronger conclusions concerning risk of future disease in paediatric populations in general.

Aim: The dramatic rise in childhood obesity incidence in developing countries is related to nutrition and lifestyle transition. The aim of this review was to evaluate the quality and reporting of dietary assessment methods used in studies examining the relationship between dietary outcome and childhood obesity in developing Asian countries. Methods: A three-step search strategy was conducted in databases between inception and 2011 with an English language restriction. Inclusion criteria were any cross-sectional or cohort studies in children =18 years who resided in developing countries in Asian region that included reporting on dietary intake. Papers were screened with standardised tools for quality and dietary methodology reporting. Results: The search process identified 2080 studies and 15 studies (in 16 articles) met inclusion criteria. The most commonly used dietary assessment method was dietary questionnaires (n = 10), followed by 24-hour diet recall (n = 4), food frequency questionnaire (n = 3) and an unweighed food record (n = 1). For dietary methodology reporting, 12 out of 16 articles were rated as 'poor', 3 rated as 'acceptable' and 1 as 'excellent'. Conclusions: The quality rating was influenced by the dietary assessment tool chosen, and a quality rating of 'poor' was mostly obtained by studies using non-standardised, non-validated study-specific dietary questionnaires. Significant gaps were identified in dietary intake methodological quality and hence, there is an urgent need for valid dietary measures and reporting of dietary intake among overweight children for studies conducted in Asian region. © 2014 Dietitians Association of Australia.

Aim: Overweight and obesity prevalence is high among adolescent girls of low socioeconomic position and this increases their risk of cardiovascular disease and metabolic disorders in adulthood. The aim of this present study was to describe the dietary patterns of adolescent girls in terms of the relative contribution of core food groups to overall diet and by weight status category. Methods: Year 8 female students were recruited from schools in low-income communities. Weight status (i.e. underweight, healthy weight, overweight, obese) was determined using age- and sex-adjusted body mass index (BMI; z score). Dietary intakes were assessed using a validated semi-quantitative food frequency questionnaire. Individual foods were collated into core food group or energy-dense, nutrient-poor categories in line with the Australian Guide to Healthy Eating (AGHE) and the percentage contribution to total energy intake calculated. Results: Participants (n = 332) were (mean ± SD) 13.7 ± 0.4 years old with BMI z score 0.63 ± 1.22. Few girls met AGHE core food group recommendations for daily serves; meat and substitutes 69.3%, vegetables 28.6%, fruit 23.8%, dairy 15.7% and breads/cereals 5.7%. Total percentage energy derived from energy-dense, nutrient-poor foods was 46.6% (37.2-54.6%) (median (interquartile range)), with takeaways 9.8% (7.0-13.6%), confectionery 7.0% (4.1-10.9%) and packaged snacks 6.8% (4.0-10.7%), with no significant differences by weight status. Conclusions: Core food intakes are poor with excessive consumption of energy-dense, nutrient-poor foods in these adolescent girls. Nutrition education programs targeting this population are needed to address this imbalance. Strategies could include substitution of unhealthy snacks for core food items and greater inclusion of core foods within main meals. © 2013 Dietitians Association of Australia.

Objective To examine associations of volumes and bouts of sedentary behavior (SED) and moderate-to-vigorous physical activity (MVPA) with individual and clustered cardio-metabolic outcomes in overweight/obese children. Methods Cross-sectional data from 120 overweight/obese children (8.3 ± 1.1 years, 62% girls, 74% obese) with SED and MVPA assessed using accelerometry. Children were categorized into quartiles of mean bouts per day of SED (10, 20, and 30 min) and MVPA (5, 10, and 15 min). Associations with triglycerides, HDL cholesterol, glucose, insulin, systolic/diastolic blood pressure, and clustered cardio-metabolic risk (cMet) were examined using linear regression, adjusted for confounders. Results Independent of MVPA, SED volume was inversely associated with HDL cholesterol (ß [95% CI] = -0.29 [-0.52, -0.05]). MVPA volume was inversely associated with diastolic blood pressure, independent of SED (ß = -0.22 [-0.44, -0.001]), and cMet (ß = -0.19 [-0.36, -0.01]) although not after adjustment for SED (ß = -0.14 [-0.33, 0.06]). Independent of MVPA and SED volumes, participants in the highest quartile of 30 min bouts per day of SED had 12% lower HDL cholesterol than those in the lowest quartile (d = 0.53, P = 0.046, Ptrend = 0.11). Conclusions In addition to increasing MVPA, targeting reduced SED and limiting bouts of SED to <30 min may contribute to improved HDL cholesterol levels and cardio-metabolic health in overweight/obese children.

Background: A direct association between parenting style and child feeding behaviours has not been established. This review explores whether an authoritative, authoritarian or permissive parenting style is associated with parental pressure to eat, responsibility, monitoring or restriction of child dietary intake. Methods: A search of eight electronic health databases was conducted. Inclusion criteria were children aged <12 years, published between 1975 and 2012, measured and reported associations between parenting style and child feeding behaviours. Results: Seven studies (n = 1845) were identified in the review. An authoritarian parenting style was associated with pressuring a child to eat and having restrictive parental food behaviours. Authoritative parenting was associated with parental monitoring of child food intake. A permissive parenting style was inversely related to monitoring of child dietary intake. Conclusions: Parenting styles showed only weak to moderate associations with individual domains of child feeding. The most consistent relationship found was a negative association between permissive parenting and monitoring for both mothers and fathers in two studies. Progress in this field could be achieved by conducting studies targeting fathers and culturally diverse populations, and development of a tool which could reflect overall child feeding behaviour rather than individual domains.

Background & aims: The aim of this study was to (i) to compare the accuracy of reporting for child's total energy intake from a food frequency questionnaire (FFQ) completed independently by the mother, father and child in comparison to total energy expenditure (TEE) measured using doubly labeled water (DLW) (ii) compare the accuracy of the weighed food record (WFR) and DLW. Methods: Healthy weight children (mean±SD age 9.8±1.3years, n=6 girls/3 boys) and their parents independently completed an FFQ about children's intake. A 4-day WFR of child intake was recorded simultaneously. The accuracy of energy intakes reports were determined by the absolute and percentage differences between estimated energy intake and TEE measured by DLW. Results: The mean difference (limits of agreement LOA, ±2SD) when compared to DLW was; child 130 (-1518, 1258)kcal or (113±35% of TEE); father 398 (0,796)kcal or (121±13%); mother 807 (-213, 1824)kcal or (144±26%) and for the WFR-153 (1089,-1395)kcal or 95±32%. Conclusions: Children were the most accurate reporters when compared to their parents, with fathers more accurate than mothers. The 4-day WFR was approximately equal to the child report FFQ in estimating EI in children 8-11 years. © 2012 Elsevier Ltd and European Society for Clinical Nutrition and Metabolism.

OBJECTIVES:: Community-based nutrition interventions aimed at influencing child dietary intake are rarely evaluated. We hypothesised that providing self-directed nutrition and parenting resources to parents living in rural northern New South Wales, Australia, would positively affect the dietary patterns of children ages 2 to 5 years. METHODS:: A total of 146 parent-child dyads (76 boys, ages 2.0-5.9 years) were randomly assigned to either a 12-month parent-centred intervention involving self-directed education provided in CD and DVD formats, or a participant-blinded control group who received generic nutrition and physical activity information. Data were collected at baseline, 3, and 12 months. RESULTS:: Total reported energy from nutrient-dense food groups and percentage energy from energy-dense, nutrient-poor foods were high at baseline relative to estimated total energy expenditure for child age. Using random effects modelling, there were significant group-by-time effects for a reduction in mean (standard deviation) total energy intake (EI) at 12 months (-461 kJ/day (196); Pâ¿¿=â¿¿0.04). An intervention group-by-time effect on carbohydrate intake (-17.4 g/day (10.6); Pâ¿¿<â¿¿0.05) was largely attributable to decreased consumption of breads and cereals (-180 g/day (80); Pâ¿¿=â¿¿0.007). Decreases in energy-dense, nutrient-poor foods were not statistically significant. CONCLUSIONS:: The proportion of total EI from noncore foods in children in rural New South Wales is high and did not improve in response to a low-intensity nutrition intervention. Parents reported small changes in consumption frequency for core and noncore food intakes, leading to a reduction in total EI. Strategies to increase resource use such as prompting via e-mail are required to further explore the effectiveness of nutrition resource dissemination at a population level.

Aim: The objective of the present study was to assess the feasibility and acceptability of an after-school obesity prevention strategy for families. Methods: Ten children aged 5-12 years and their parents/guardians from an economically disadvantaged area participated in an after-school healthy lifestyle program, which was run over a school term. It consisted of five face-to-face sessions that were run fortnightly with an additional social barbeque session at program completion. Results: Feasibility was demonstrated by successful recruitment, retention (80%) and collection of a high percentage of usable data (96% at baseline, 80% at follow up). Acceptability was demonstrated by a session attendance of 83%, 100% positive enjoyment response. There was no significant change in anthropometrics, child or adult fruit and vegetable intake with no or little effect on all other dietary variables. Conclusions: The present study illustrated an approach to the translation of a program used in an evidence-based efficacious clinical trial into a sustainable community setting. © 2013 Dietitians Association of Australia.

Objective: This study examines the associations between objectively measured sedentary behavior, light physical activity (LPA), and moderate-to-vigorous physical activity (MVPA), and plasma lipids in overweight and obese children. Design and Methods: Cross-sectional analyses were conducted among 126 children aged 5.5-9.9 years. Sedentary behavior, LPA, and MVPA were assessed using accelerometry. Fasting blood samples were analyzed for plasma lipids (high-density lipoprotein cholesterol [HDL-C], low-density lipoprotein cholesterol [LDL-C], total cholesterol [TC], and triglycerides [TG]). Results: MVPA was not related to plasma lipids (P > 0.05). Independent of age, sex, energy intake, and waist circumference z-score, sedentary behavior and LPA were associated with HDL-C (ß = -0.23, 95% CI -0.42 to -0.04, P = 0.020; ß = 0.20, 95% CI 0.14 to 0.39, P = 0.036, respectively). The strength of the associations remained after additionally adjusting for MVPA (sedentary behavior: ß = -0.22, 95% CI -0.44 to 0.006, P = 0.056; LPA: ß = 0.19, 95% CI -0.005 to 0.38, P = 0.056, respectively). Conclusion: Substituting at least LPA for sedentary time may contribute to the development of healthy HDL-C levels among overweight and obese children, independent of their adiposity. Comprehensive prevention and treatment strategies to improve plasma HDL-C among overweight and obese children should target reductions in total sedentary time and promote the benefits of LPA, in addition to promoting healthy levels of adiposity, healthy dietary behaviors, and MVPA.

Objective: To evaluate whether a child-centered physical activity program, combined with a parent-centered dietary program, was more efficacious than each treatment alone, in preventing unhealthy weight-gain in overweight children. Study design: An assessor-blinded randomized controlled trial involving 165 overweight/obese 5.5- to 9.9- year-old children. Participants were randomly assigned to 1 of 3 interventions: a parent-centered dietary program (Diet); a child-centered physical activity program (Activity); or a combination of both (Diet + Activity). All groups received 10 weekly face-to-face sessions followed by 3 monthly relapse-prevention phone calls. Analysis was by intention-to-treat. The primary outcome was change in body mass index z-score at 6 and 12 months (n = 114 and 106, respectively). Results: Body mass index z-scores were reduced at 12-months in all groups, with the Diet (mean [95% confidence interval]) (-0.39 [-0.51 to 0.27]) and Diet + Activity (-0.32, [-0.36, -0.23]) groups showing a greater reduction than the Activity group (-0.17 [-0.28, -0.06]) (P = .02). Changes in other outcomes (waist circumference and metabolic profile) were not statistically significant among groups. Conclusion: Relative body weight decreased at 6 months and was sustained at 12 months through treatment with a child-centered physical activity program, a parent-centered dietary program, or both. The greatest effect was achieved when a parent-centered dietary component was included. © 2010 Mosby Inc. All rights reserved.
