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.

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.

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.

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: To investigate associations between changes in vegetable and fruit (V&F) intakes and anthropometric indices (weight, BMI, % body fat, waist circumference), including differences by sex, during a dietary weight-loss intervention. Methods: Adults (18-45 years) with overweight/obesity (BMI 25-35 kg/m2) entered a 10-week pre-post study, receiving individualised consults with an Accredited Practising Dietitian targeting increased V&F intakes. Dietary intake was assessed using 24-hour recalls and food frequency questionnaires. Linear mixed models were used to examine how much of the changes in anthropometric indices were explained by changes in V&F intakes. Sex differences were assessed by Wilcoxon rank sum tests. Results: Of the 43 participants enrolled, 34 completed the study (53% female). Significant differences in energy intake and anthropometric indices were observed between males and females at baseline. After 10 weeks, females significantly reduced their weight (-2.9%, P <.01), BMI (-0.82 kg/m2, P <.01), waist circumference (-1.70 cm, P <.01), energy intake (-824 kJ/day, P =.01) and improved diet quality (-14.0% energy-dense, nutrient-poor foods, P <.01). Males significantly reduced weight (-2.5%, P =.04), BMI (-0.76 kg/m2, P =.03), waist circumference (-2.40 cm, P =.02), energy intake (-2875 kJ/day, P <.01), increased fruit intake (+0.89 serves/day, P =.02) and improved diet quality (-6% energy-dense, nutrient-poor foods, P <.01). Compared to the other sex, greater reductions were observed in energy intake in males and energy-dense, nutrient-poor foods in females. Linear mixed models identified that changes in V&F intakes did not explain the variation in anthropometric measures. Conclusion: Future interventions may benefit from trialling sex tailored messages to enhance effects on anthropometric changes.

The prevalence of Gestational Diabetes Mellitus (GDM) increased from 7% to 13.1% between 2013 and 2017 in NSW, Australia. Limited detail has been reported on dietary patterns prior to GDM diagnosis. Aim: To evaluate adequacy of micronutrient intakes and contribution of nutrient-dense versus energy-dense, nutrient-poor food groups to total energy. Method: Dietary intake of women with GDM was assessed over the six months prior to attending the first outpatient nutrition education group using the Australian Eating Survey: food frequency questionnaire with food group serves compared to the Australian Guide to Healthy Eating recommendations. Nutrient intakes compared to Estimated Average Requirements (EARs). Diet quality was evaluated using the Australian Recommended Food Score diet quality index. Results: Fifty women with a mean age of 30.8±4.6 years completed the Australian Eating Survey. Mean percentage (SD) energy intake derived from nutrient-dense versus energy-dense, nutrient-poor foods was 66.6% (12.4) and 33.4% (12.4); respectively. Median intakes of iron, calcium, fibre, iodine and folate were below EARs. Median (IQR) total Australian Recommended Food Score was 31(15) from a maximum 73 points. Adherence to the Australian Guide to Healthy Eating recommendations was low, with no participants meeting recommendations for serves of bread and cereals, 92% below dairy and dairy alternatives and 82% below vegetable intake recommendations. Conclusions: Before being diagnosed with GDM, women derive a high percentage of total energy from energy-dense, nutrient-poor foods, have low dietary variety amongst nutrient-dense foods, and sub-optimal intakes of key pregnancy micronutrients. Poor dietary patterns require attention within medical nutrition therapy for GDM in order to optimise nutrition-related health outcomes.

Objectives: In order to manage blood glucose levels in pregnancy, women need to know what and how much to eat, particularly for foods containing carbohydrate. The aim was to assess pregnant women¿s carbohydrate and standard serve size knowledge and examine whether health professionals provided nutrition education. Methods: Between July 2017 and April 2018 Australian pregnant women were recruited to complete an online survey, including a modified PedCarbQuiz carbohydrate knowledge questionnaire and an online buffet, where they selected images equivalent to one Australian Guide to Healthy Eating (AGHE) standard serve size. Results: 186 pregnant women (mean age 30.9¿years, SD = 4.7¿years) 12¿22¿weeks gestation completed the survey. Participants achieved a median score of 27/36 for identification of carbohydrate-containing foods and a median score of 1/12 (range 0¿11) for identification of grams of carbohydrate in specific portions. Participants achieved a median score of 14/22 (range 4¿19) for identification of one AGHE standard serve of 11 carbohydrate-containing foods. Less than half (n = 92, 49.5%) received nutrition education from health professionals. Conclusions for Practice: Pregnant women had sub-optimal carbohydrate knowledge. This could contribute to impaired blood glucose concentrations and risk of adverse health outcomes in pregnancy. Opportunities for pregnant women to access nutrition advice from health professionals should be explored.

Aim: The nutritional quality of foods consumed by infants and young children to complement breastfeeding or formula feeding influences growth and development. The aim of this study was to identify the dietary intake of Indigenous infants and young children in the Gomeroi gaaynggal cohort, and evaluate the nutritional adequacy of their intake compared with Australian recommendations. Methods: Dietary intake was assessed using diet recalls at approximately 9-, 12- and 24-month visits. Nutrient values of foods were obtained from AUSNUT 2011-13 and nutrient intake compared to the Australian Nutrient Reference Values. Foods were categorised into food groups and intakes compared to the Australian Guide to Healthy Eating. Results: A total of 206 infants and young children were included in the study. Of these, 95 individual children had dietary data collected between 7.6 and 24.7¿months. Infant formula and breastfeeding rates were highest among infants (70% and 20%, respectively). Cow's milk intake was highest among young children (75%). Infants and young children in the cohort met most macro- and micronutrient intake recommendations. Few young children met recommendation for iron (42%), no infant met recommendation for omega-3 fatty acids and almost all exceeded recommendation for sodium. Most young children met daily dairy and fruit recommendations although intake of discretionary foods was high. Conclusions: This study found that diets of Indigenous infants and young children met most key nutrient reference targets. Potential target areas that require dietary optimisation have been identified and will be the focus of community-led strategies in adequate infant nutrition promotion.

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<.001).

Background: Dietary intake is an important modifiable risk factor for cardiovascular disease. However, to our knowledge, there are no systematic reviews of nutrition interventions in the context of cardiovascular disease prevention and management within rural communities. This is important to investigate, given the unique geographic, social, and contextual factors associated with rurality. Objective: Our primary objective was to systematically assess evidence on the effectiveness of randomized controlled trials to improve dietary intake in the context of cardiovascular disease prevention and management in rural communities. Methods: Nine electronic databases were searched from inception to June 2020, including MEDLINE, The Cochrane Library, Embase, Emcare, PsycINFO, Scopus, Rural and Remote Health, CINAHL, and AMED. Randomized controlled trials that reported results of interventions with adult, rural populations and measured change in dietary intake compared to usual care, alternative intervention, or no intervention controls were included. Included randomized controlled trials were also assessed according to the TIDieR (Template for Intervention Description and Reporting) checklist and RE-AIM (reach, effectiveness, adoption, implementation, maintenance) framework. Results: Thirteen articles reporting results of randomized controlled trials were identified. Included articles reported a range of nutrition interventions and measured 18 dietary intake outcomes. Most studies (n = 10) demonstrated effectiveness in altering at least 1 dietary intake outcome, including fruit and/or vegetable (n = 9), fiber (n = 2), Dietary Risk Assessment score (n = 2), energy, dairy, carotene, vitamin C and sodium (all n = 1). However, there was wide variation in the reporting of intervention components (according to the TIDieR checklist) and impact (according to RE-AIM framework), resulting in difficulty interpreting the ¿real-world¿ implications of these results. Conclusions: Through this systematic review, we found limited evidence of improvement in dietary intakes due to nutrition interventions in the context of cardiovascular disease prevention and management in rural communities. Fruit and/or vegetable intakes were the most frequently reported dietary intake outcomes, and most likely to be improved across the included studies. Included studies were generally not well reported, which may hinder replication by clinicians and consolidation of the evidence base by other researchers. Given the substantial burden of cardiovascular disease experienced by those living in rural areas of developed countries, additional high-quality nutrition research that acknowledges the complexities of rural health is required.

It is the position of Dietitians Australia that clients can receive high-quality and effective dietetic services such as Medical Nutrition Therapy (MNT) delivered via telehealth. Outcomes of telehealth-delivered dietetic consultations are comparable to those delivered in-person, without requiring higher levels of additional training nor compromising quality of service provision. Dietitians Australia recommends that policy makers and healthcare funders broaden the recognition for telehealth-delivered dietetic consultations as a responsive and cost-effective alternative or complement to traditional in-person delivery of dietetic services. The successful implementation of telehealth can help to address health and service inequalities, improve access to effective nutrition services, and support people with chronic disease to optimise their diet-related health and well-being, regardless of their location, income or literacy level, thereby addressing current inequities.

Introduction: A lack of core food accessibility negatively affects diet quality, potentially increasing the prevalence of health risk factors such as obesity. The purpose of this study was to investigate core food access in an Australian regional center through the use of data visualization techniques. Methods: Supermarkets were used as a proxy for core food accessibility and were identified and mapped by town region with a combination of Google Maps and Stata/IC 15.1 software. A statistical analysis comparing the demographics of each town region was also completed using Stata. Results: The maps generated suggest that there may be a disparity in core food accessibility between town regions. The analysis of demographics demonstrated that one town region had a greater proportion of disadvantaged residents, with statistically significant variation between regions. Conclusion: Data visualization and analysis may be a useful tool for clinicians to communicate accessibility information experienced by local residents. This need not be limited to food accessibility and extended to health services.

Introduction: An optimal diet is imperative in preparing women for pregnancy and this may be influenced by socio-economic status (SES). This research aims to investigate the role of SES on the dietary energy density (ED) in Australian women of preconception age. Methods: A secondary analysis of the Australian National Nutrition and Physical Activity Survey 2011¿12 for females aged 18¿39¿years (n¿=¿1617) was conducted. Dietary intake was assessed by 24-hr recalls and dietary ED by dietary energy per weight (kJ.g-1). ED was further categorised as ED of foods and beverages separately. SES was assessed by three variables: Socio-Economic Indexes for Areas (SEIFA), developed by the Australian Bureau of Statistics; income decile; and level of education. Linear mixed model regressions were used to identify associations between ED and SES. Results: The median ED for food, beverages and combined food and beverages was 9.38¿kJ g-1, 1.02 kJ g-1 and 7.11¿kJ g-1, respectively. No significant variation was explained by SES variables when analysing combined ED in the adjusted model or ED from foods. Income decile reduced ED of beverages, although with little effect (coefficient: -0.04, P¿=¿0.002). Significant confounders included inactivity, which increased ED in both combined ED and ED foods (coefficient: 0.51, P¿=¿0.001 and coefficient: 0.78, P¿<¿0.001). Conclusions: SES explained little variation in dietary ED in women of childbearing age. A large proportion of women had high energy-dense diets regardless of their SES. These findings suggest that a large proportion of women, who may become pregnant, have diets that exceed the international recommendations for dietary energy density.

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.

Dietary intakes are commonly assessed by established methods including food frequency questionnaires, food records, or recalls. These self-report methods have limitations impacting validity and reliability. Dietary biomarkers provide objective verification of self-reported food intakes, and represent a rapidly evolving area. This review aims to summarize the urinary biomarkers of individual foods, food groups, dietary patterns, or nutritional supplements that have been evaluated to date. Six electronic databases were searched. Included studies involved healthy populations, were published from 2000, and compared measured dietary intake with urinary markers. The initial search identified 9985 studies; of these, 616 full texts were retrieved and 109 full texts were included. Of the included studies, 67 foods and food components were studied, and 347 unique urinary biomarkers were identified. The most reliable biomarkers identified were whole grains (alkylresorcinols), soy (isoflavones), and sugar (sucrose and fructose). While numerous novel urinary biomarkers have been identified, further validation studies are warranted to verify the accuracy of self-reported intakes and utility within practice.

The impact of pre-pregnancy obesity and maternal diet quality on the use of healthcare resources during the perinatal period is underexplored. We assessed the effects of body mass index (BMI) and diet quality on the use of healthcare resources, to identify whether maternal diet quality may be effectively targeted to reduce antenatal heath care resource use, independent of women¿s BMI. Cross-sectional data and inpatient medical records were gathered from pregnant women attending publicly funded antenatal outpatient clinics in Newcastle, Australia. Dietary intake was self-reported, using the Australian Eating Survey (AES) food frequency questionnaire, and diet quality was quantified from the AES subscale, the Australian Recommended Food Score (ARFS). Mean pre-pregnancy BMI was 28.8 kg/m2 (range: 14.7 kg/m2¿64 kg/m2). Mean ARFS was 28.8 (SD = 13.1). Higher BMI was associated with increased odds of caesarean delivery; women in obese class II (35.0¿39.9 kg/m2) had significantly higher odds of caesarean delivery compared to women of normal weight, (OR = 2.13, 95% CI 1.03 to 4.39; p = 0.04). Using Australian Refined Diagnosis Related Group categories for birth admission, the average cost of the birth admission was $1348 more for women in the obese class II, and $1952 more for women in the obese class III, compared to women in a normal BMI weight class. Higher ARFS was associated with a small statistically significant reduction in maternal length of stay (RR = 1.24, 95% CI 1.00, 1.54; p = 0.05). There was no evidence of an association between ARFS and mode of delivery or ¿midwifery-in-the-home-visits¿.

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.

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: 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.

Objectives:The objective of this systematic review was to evaluate the effectiveness of interventions that include a nutrition component aimed at improving gestational weight gain and/or postpartum weight retention.Introduction:Excessive gestational weight gain and postpartum weight retention increase the risk of adverse maternal and neonatal outcomes. Current evidence comprises many interventions targeting gestational weight gain and postpartum weight retention that incorporate a nutrition component. To date, no review has synthesized evidence from pregnancy through the postpartum period or described the intervention approaches in detail.Inclusion criteria:The review included women (=18 years) during pregnancy and/or up to 12 months postpartum. Studies were included if they involved a weight management intervention with a nutrition component and had the primary objective of determining the impact of gestational weight gain and/or postpartum weight change. Interventions were compared to usual care (i.e. control conditions with no intervention or wait-list control or standard pregnancy or postpartum care) or "other" (alternative intervention). The review considered randomized controlled trials published between 1980 and January 21, 2016. Studies that included a weight related primary outcome measured during pregnancy and/or postpartum were included.Methods:Seven databases were searched and the reference lists of included studies were searched for additional studies not previously identified. Two independent reviewers assessed the methodological quality of studies using the Joanna Briggs Institute Meta-Analysis of Statistics Assessment and Review Instrument (JBI SUMARI). The JBI SUMARI standardized data extraction tool was used to extract data. A narrative synthesis was undertaken to qualitatively synthesize included studies, with meta-analyses used to pool weight outcome data from studies conducted separately for pregnancy and postpartum. Effect sizes for meta-analyses have been expressed as weighted mean differences (95% confidence intervals).Results:The search yielded 4063 articles of which 48 articles from 39 studies were included. Eleven of 20 studies during pregnancy reported significant reductions in gestational weight gain with the intervention when compared to control groups. One of five studies where the intervention was conducted during both pregnancy and postpartum reported statistically significant reductions in gestational weight gain, and postpartum weight retention between intervention and control groups. Nine of 14 studies conducted after childbirth reported statistically significant intervention effects, indicating lesser postpartum weight retention. Random effects meta-analyses indicated that despite considerable heterogeneity, interventions conducted during pregnancy (-1.25 kg; 95% CI:-2.10 kg,-0.40 kg; p = 0.004), and postpartum (-3.25 kg; 95% CI:-4.69 kg,-1.82 kg; p < 0.001) were significantly more effective at improving weight outcomes compared to usual care or other interventions. Most studies were of moderate quality due to lack of clarity in describing study details required for appraising methodological quality. Few interventions were conducted from pregnancy through the postpartum period (n = 5). Limited interventions adopted online modalities in intervention delivery (n = 4). Intention-to-treat analysis was used in only 12 studies.Conclusions:The pregnancy and postpartum period presents a unique opportunity to engage women in interventions to help optimize lifestyle behaviors for weight management, however the optimal approach is unclear. Improving consistency in intervention implementation and reporting will improve future evidence synthesis.

Background: Primary healthcare dietitians have a vital role to play in the prevention and management of chronic disease. Working in primary care requires efficient and effective management of practice to ensure client and practitioner needs are met. The present study aimed to explore the way in which primary care dietitians in Australia view the constructs of efficiency and effectiveness within the context of their practice. Methods: The study used an exploratory qualitative design within a pragmatist framework. Individual semi-structured telephone interviews were conducted with Australian primary care dietitians. All interviews were audio-recorded, transcribed verbatim and analysed using an inductive thematic approach. Results: Twenty dietitians (17 females) working as private practitioners in primary care from three Australian states participated in the present study. Three themes emerged from the data. The first theme revealed that seeking efficiency and especially effectiveness were important to primary care dietitians and that there was a tension between the two. The second theme identified that efficiency and effectiveness are influenced by personal and structural factors. The final theme explored how dietitians are actively seeking ways to be more efficient and effective, including supportive networks, as well as the utilisation of technology. Conclusions: Achieving a balance between efficiency and effectiveness in primary care dietetics is challenging to practitioners, who may require further training and support to enhance productivity, time management and resource utilisation. Structured issues exist for the workface. Further studies are required to quantify these findings and to explore whether it is possible to optimise efficiency and effectiveness and achieve sustainability of the dietetic workforce in primary care.

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.

Objective: Human skin colour is influenced by three pigments: haemoglobin, carotenoids, and melanin. Carotenoids are abundant in fruits and vegetables, and when consumed accumulate in all layers of the skin, predominantly imparting yellowness (b*). This study investigated the effect of the manipulation of carotenoid-based skin colour, relative to the skin colour conferred by melanin on the perceptions of health amongst a group of Australian adults. Method: Fifty-seven participants (n = 4 male; mean age 27.9 ± 7.5 years) completed three computer-based experiments on 50 trial faces. In the first two experiments, face image colour was manipulated along one or two independent single carotenoid or melanin axes on each trial to ¿make the face appear as healthy as possible¿. In the third trial, face colour was manipulated on both the carotenoid and melanin axes simultaneously. Results: For the single axis, participants significantly increased melanin colouration and added carotenoid colouration to facial images that were initially low in skin yellowness (b*). When carotenoid and melanin axes were simultaneously manipulated, carotenoid colouration was raised (¿E = 3.15 (SE ±0.19)) and melanin colouration was lowered (¿E = -1.04 (SE ±0.1)). Conclusions: Young Australian adults perceive facial skin colouration, associated with both carotenoid intake from fruit and vegetables and melanin due to sun exposure as conveying the appearance of health in young adults. However, carotenoid colouration was more important to health perception.

Background: Childhood nutrition is important in optimising growth, development and future health. The present study compared dietary intakes of Australian children aged 4¿8 years with (i) Australian Guide to Healthy Eating (AGHE) food group recommendations and (ii) age-specific Nutrient Reference Values (NRVs), in addition to (iii) describing food group intakes of children meeting key NRVs. Methods: Data were obtained from a representative sample of children (n = 789) from the National Nutrition and Physical Activity Survey between May 2011 and June 2012. Parent-reported 24-h recall dietary data were disaggregated into five core food groups, along with energy-dense, nutrient-poor (EDNP) foods, with intakes being compared with AGHE recommendations. Food group intakes were compared for children meeting the NRVs for 10 nutrients used for the development of AGHE food groups. Chi-squared and t-tests were performed to determine differences in food group intakes with P < 0.05 considered statistically significant. Results: Only one child met the recommended daily servings for all AGHE core food groups and none met both core and energy-dense, nutrient-poor (EDNP) food group recommendations. The lowest level of alignment (percentage meeting recommendations) was for vegetables (4.6%) and the highest was for fruit (47.7%). Mean (SD) daily intake of EDNP foods [4.7 (3.2) serves day-1] accounted for 38.4% of total energy intakes. Children meeting key NRVs (n = 395) consumed greater daily servings of fruit [2.2 (1.7)], dairy [2.2 (1.2)] and EDNP foods [5.0 (3.4)] compared to the total sample (n = 789). Conclusions: Significant discrepancies exist between contemporary dietary patterns of Australian children and national recommendations. Future AGHE revisions should incorporate greater diversity of consumption patterns, including sub-categories of EDNP foods.

Objective To integrate the findings of research on electronic personal health records (e-PHRs) for an understanding of their health literacy demands on both patients and providers. Methods We sought peer-reviewed primary research in English addressing the health literacy demands of e-PHRs that are online and allow patients any degree of control or input to the record. A synthesis of three theoretical models was used to frame the analysis of 24 studies. Results e-PHRs pose a wide range of health literacy demands on both patients and health service providers. Patient participation in e-PHRs relies not only on their level of education and computer literacy, and attitudes to sharing health information, but also upon their executive function, verbal expression, and understanding of spoken and written language. Conclusion The multiple health literacy demands of e-PHRs must be considered when implementing population-wide initiatives for storing and sharing health information using these systems. Practice implications The health literacy demands of e-PHRs are high and could potentially exclude many patients unless strategies are adopted to support their use of these systems. Developing strategies for all patients to meet or reduce the high health literacy demands of e-PHRs will be important in population-wide implementation.

Young adult men are under-represented in health research, and little is known about how to reach and engage them in lifestyle interventions. This mixed-methods study aimed to explore young males¿ preferences for recruitment strategies, content, format (delivery mode and program duration and frequency), and facilitator characteristics for future physical activity and nutrition interventions. Ten focus groups involving 61 men (aged 18¿25 years) in the Hunter region, New South Wales, Australia and an online survey distributed within Australia were completed by 282 males (aged 18¿25 years). Key focus group themes included a preference for recruitment via multiple sources, ensuring images and recruiters were relatable; intervention facilitators to be engaging and refrain from discussing negative consequences of being unhealthy. Key program content preferences included skill development and individualized goals and feedback. Focus groups and the survey confirmed a preference for multiple delivery modes, including; face-to-face (group and individual), with support using eHealth technologies. Survey results confirmed the most favored program content as: ¿healthy eating on a budget,¿ ¿quick and easy meals,¿ and ¿resistance training.¿ Focus group responses suggested a program duration of =6 months, with 2¿3 combined face-to-face and supportive eHealth sessions per week. Survey intervention duration preference was 3 months with 4 face-to-face sessions per month. Findings can guide the design, conduct, and evaluation of relevant contemporary physical activity and or nutrition interventions for young men. There is a need to identify the most effective ways to address young men¿s individual preferences in intervention research.

Many Australian young men (18-25 years) fail to meet recommendations in national dietary or physical activity (PA) guidelines. However, there is a lack of understanding of their perspectives on PA and diet to inform intervention design. This study examined young men¿s motivators and barriers to healthy eating and PA, along with differences by demographic and behavioral factors. A cross-sectional online survey was completed by 282 men aged 18 to 25 years in Australia. Results identified the most common motivators for healthy eating included improving health (63.5%), body image (52.3%), and increasing energy (32.1%). Motivators for PA included improving body image (44.6%), fitness (44.2%), and health (41.0%). Common barriers to healthy eating were access to unhealthy foods (61.1%), time to cook/prepare healthy foods (55.0%), and motivation to cook healthy foods (50.7%). Barriers for PA included motivation (66.3%), time (57.8%), and cost of equipment/facilities (33.3%). Significant differences (p <.01) in motivators to healthy eating and/or PA were identified for BMI category, marital status, PA level, alcohol intake, and stress levels. Significant differences were identified for barriers to healthy eating and/or PA by BMI, PA level, stress, and fruit and vegetable intake, assessed using Pearson¿s chi-square test. Findings suggest that promotion of benefits related to health, appearance/body image, increased energy and fitness, and addressing key barriers including motivation, time, financial restraints, and accessibility of unhealthy foods, could engage young men in improving lifestyle behaviors. Differences by demographic and behavioral factors suggest development of tailored programs to address diversity among young men may be required.

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.

Diabetes is a chronic, complex condition requiring sound knowledge and self-management skills to optimize glycemic control and health outcomes. Dietary intake and physical activity are key diabetes self-management (DSM) behaviors that require tailored education and support. Electronic health (eHealth) technologies have a demonstrated potential for assisting individuals with DSM behaviors. This review provides examples of technologies used to support nutrition and physical activity behaviors in the context of DSM. Technologies covered include those widely used for DSM, such as web-based programs and mobile phone and smartphone applications. In addition, examples of novel tools such as virtual and augmented reality, video games, computer vision for dietary carbohydrate monitoring, and wearable devices are provided. The challenges to, and facilitators for, the use of eHealth technologies in DSM are discussed. Strategies to support the implementation of eHealth technologies within practice and suggestions for future research to enhance nutrition and physical activity behaviors as a part of broader DSM are provided.

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.

Indigenous Australians have high rates of chronic diseases, the causes of which are complex and include social and environmental determinants. Early experiences in utero may also predispose to later-life disease development. The Gomeroi gaaynggal study was established to explore intrauterine origins of renal disease, diabetes and growth in order to inform the development of health programmes for Indigenous Australian women and children. Pregnant women are recruited from antenatal clinics in Tamworth, Newcastle and Walgett, New South Wales, Australia, by Indigenous research assistants. Measures are collected at three time points in pregnancy and from women and their children at up to eight time points in the child's first 5 years. Measures of fetal renal development and function include ultrasound and biochemical biomarkers. Dietary intake, infant feeding and anthropometric measurements are collected. Standardized procedures and validated tools are used where available. Since 2010 the study has recruited over 230 women, and retained 66 postpartum. Recruitment is ongoing, and Gomeroi gaaynggal is currently the largest Indigenous pregnancy-through-early-childhood cohort internationally. Baseline median gestational age was 39.1 weeks (31.5-43.2, n=110), median birth weight was 3180 g (910-5430 g, n=110). Over one third (39.3%) of infants were admitted to special care or neonatal nursery. Nearly half of mothers (47.5%) reported tobacco smoking during pregnancy. Results of the study will contribute to knowledge about origins of chronic disease in Indigenous Australians and nutrition and growth of women and their offspring during pregnancy and postpartum. Study strengths include employment and capacity-building of Indigenous staff and the complementary ArtsHealth programme.

Nudging or 'choice architecture' refers to strategic changes in the environment that are anticipated to alter people's behaviour in a predictable way, without forbidding any options or significantly changing their economic incentives. Nudging strategies may be used to promote healthy eating behaviour. However, to date, the scientific evidence has not been systematically reviewed to enable practitioners and policymakers to implement, or argue for the implementation of, specific measures to support nudging strategies. This systematic review investigated the effect of positional changes of food placement on food choice. In total, seven scientific databases were searched using relevant keywords to identify interventions that manipulated food position (proximity or order) to generate a change in food selection, sales or consumption, among normal-weight or overweight individuals across any age group. From 2576 identified articles, fifteen articles comprising eighteen studies met our inclusion criteria. This review has identified that manipulation of food product order or proximity can influence food choice. Such approaches offer promise in terms of impacting on consumer behaviour. However, there is a need for high-quality studies that quantify the magnitude of positional effects on food choice in conjunction with measuring the impact on food intake, particularly in the longer term. Future studies should use outcome measures such as change in grams of food consumed or energy intake to quantify the impact on dietary intake and potential impacts on nutrition-related health. Research is also needed to evaluate potential compensatory behaviours secondary to such interventions.

Background: Excessive gestational weight gain (GWG) is associated with adverse maternal-child health outcomes. Managing energy intake and GWG versus optimising nutrient intake can be challenging. The present study aimed to examine the relationships between dietary portion size, GWG and nutrient intakes during pregnancy. It is hypothesised that, after adjustment for potential confounders, portion size would be positively associated with both GWG and nutrient intakes during pregnancy. Methods: Prospective data were obtained for 179 Australian women from the Women and Their Children's Health Study. A validated food frequency questionnaire was used at 18-24 and 36-40 weeks of gestation to quantify diet and portion size during the previous 3 months of pregnancy. Nutrient intakes were compared with Australian Nutrient Reference Values (NRVs). GWG was measured up to 36 weeks and compared with the Institute of Medicine weight gain recommendations (WtAdh). Results: In multivariate regression models, portion size factor (PSF) was positively associated with GWG in women with high socio-economic status (SES; ß = 0.20, P = 0.04) and those with an overweight/obese pre-pregnancy body mass index (BMI) (ß = 0.28, P = 0.04). PSF uniquely accounted for 8.2% and 3.7% of the variability in GWG for women with high SES and overweight/obese pre-pregnancy BMIs, respectively. Nutrient intakes and PSF were similar regardless of WtAdh. Women achieved NRVs for calcium and zinc in all PSF categories. Most of the women with large PSF still failed to achieve the NRVs for folate (95.7%), iron (89.6%) and fibre (85.5%). Conclusions: All women require advice on quality food choices during pregnancy to optimise health outcomes. Targeting portion size alone is insufficient to manage GWG but may prove to be a valuable tool in pregnant women of high SES and/or those who are overweight/obese pre-pregnancy.

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.

Adherence and accuracy of self-monitoring of dietary intake influences success in weight management interventions. Information technologies such as computers and smartphones have the potential to improve adherence and accuracy by reducing the burden associated with monitoring dietary intake using traditional paper-based food records. We evaluated the acceptability and accuracy of three different 7-day food record methods (online accessed via computer, online accessed via smartphone, and paper-based). Young women (N=18; aged 23.4±2.9 years; body mass index 24.0±2.2) completed the three 7-day food records in random order with 7-day washout periods between each method. Total energy expenditure (TEE) was derived from resting energy expenditure (REE) measured by indirect calorimetry and physical activity level (PAL) derived from accelerometers (TEE=REE×PAL). Accuracy of the three methods wasassessed by calculating absolute (energy intake [EI]-TEE) and percentage difference (EI/TEE×100) between self-reported EI and TEE. Acceptability was assessed via questionnaire. Mean±standard deviation TEE was 2,185±302 kcal/day and EI was 1,729±249 kcal/day, 1,675±287kcal/day, and 1,682±352 kcal/day for computer, smartphone, and paper records, respectively. There were no significant differences between absolute and percentage differences between EI and TEE for the three methods: computer, -510±389 kcal/day (78%); smartphone, -456±372 kcal/day (80%); and paper, -503±513 kcal/day (79%). Half of participants (n=9) preferred computer recording, 44.4% preferred smartphone, and 5.6% preferred paper-based records. Most participants (89%) least preferred the paper-based record. Because online food records completed on either computer or smartphone were as accurate as paper-based records but more acceptable to young women, they should be considered when self-monitoring of intake is recommended to young women.

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.

Objectives: To investigate the effectiveness of Smoking, Nutrition, Alcohol, Physical activity and Obesity (SNAPO) interventions in young men exclusively. The secondary aim was to evaluate the recruitment, retention and engagement strategies. Methods: A search with no date restrictions was conducted across seven databases. Randomized controlled trials recruiting young men only (aged 18-35. years) into interventions targeting any SNAPO risk factors were included. Results: Ten studies were included (two nutrition, six alcohol use, two targeting multiple SNAPO risk factors). Six studies (two nutrition, three alcohol use and one targeting multiple SNAPO risk factors) demonstrated significant positive short-term intervention effects, but impact was either not assessed beyond the intervention (n = 3), had short-term follow-up (= 6 months) (n = 2) or not sustained beyond six months (n = 1). Overall, a high risk of bias was identified across studies. Only one study undertook a power calculation and recruited the required sample size. Adequate retention was achieved in three studies. Effectiveness of engagement strategies was not reported in any studies. Conclusions: Despite preliminary evidence of short-term effectiveness of SNAPO interventions in young men, few studies characterized by a high risk of bias were identified. High quality SNAPO interventions for young men are 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: 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.

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.
