Background: School canteens are a recommended setting to influence adolescent nutrition due to their scope to improve student food choices. Online lunch ordering systems (¿online canteens¿) are increasingly used and represent attractive infrastructure to implement choice architecture interventions that nudge users toward healthier food choices. A recent cluster randomized controlled trial demonstrated the short-term effectiveness (2-month follow-up) of a choice architecture intervention to increase the healthiness of foods purchased by high school students from online canteens. However, there is little evidence regarding the long-term effectiveness of choice architecture interventions targeting adolescent food purchases, particularly those delivered online. Objective: This study aimed to determine the long-term effectiveness of a multi-strategy choice architecture intervention embedded within online canteen infrastructure in high schools at a 15-month follow-up. Methods: A cluster randomized controlled trial was undertaken with 1331 students (from 9 high schools) in New South Wales, Australia. Schools were randomized to receive the automated choice architecture intervention (including menu labeling, positioning, feedback, and prompting strategies) or the control (standard online ordering). The foods purchased were classified according to the New South Wales Healthy Canteen strategy as either ¿everyday,¿ ¿occasional,¿ or ¿should not be sold.¿ Primary outcomes were the average proportion of ¿everyday,¿ ¿occasional,¿ and ¿should not be sold¿ items purchased per student. Secondary outcomes were the mean energy, saturated fat, sugar, and sodium content of purchases. Outcomes were assessed using routine data collected by the online canteen. Results: From baseline to 15-month follow-up, on average, students in the intervention group ordered significantly more ¿everyday¿ items (+11.5%, 95% CI 7.3% to 15.6%; P<.001), and significantly fewer ¿occasional¿ (¿5.4%, 95% CI ¿9.4% to ¿1.5%; P=.007) and ¿should not be sold¿ items (¿6%, 95% CI ¿9.1% to ¿2.9%; P<.001), relative to controls. There were no between-group differences over time in the mean energy, saturated fat, sugar, or sodium content of lunch orders. Conclusions: Given their longer-term effectiveness, choice architecture interventions delivered via online canteens may represent a promising option for policy makers to support healthy eating among high school students.

Online school canteen lunch ordering systems may offer a unique opportunity to support the implementation of school canteen nutrition polices, while delivering behavioural interventions directly to consumers to influence healthy student purchasing. This cluster randomised controlled trial aimed to test the effectiveness of a menu audit and feedback strategy alone, and in combination with online menu labels in encouraging healthier purchasing from an online school canteen ordering system. Five intervention schools received a menu audit and feedback strategy, plus online menu labels; and five control schools received a delayed menu audit and feedback strategy. Data from 19,799 student lunch orders, containing over 40,000 items were included in the evaluation. Outcomes were assessed at baseline (pre-intervention), follow-up 1 (menu audit and feedback vs control), and follow-up 2 (menu audit and feedback plus online menu labels vs menu audit and feedback alone). From baseline to follow-up 1, the menu audit and feedback strategy alone had no significant effect on the proportion of healthy (¿Everyday¿) and less healthy (¿Occasional¿ or ¿Should not be sold¿) items purchased. From baseline to follow-up 2, schools that received menu audit and feedback plus online menu labels had significantly higher odds of students purchasing ¿Everyday¿ items (OR: 1.19; p = 0.019), and significantly lower odds of students purchasing ¿Occasional¿ (OR: 0.86; p = 0.048) and ¿Should not be sold¿ (OR: 0.52; p < 0.001) items. Menu audit and feedback with the addition of online menu labels was effective in increasing the proportion of healthy items purchased relative to menu audit and feedback in isolation. There may be a greater role for online menu labelling as part of a suite of strategies to improve public health nutrition in schools.

Objective: To assess differences between traditional paper bag ordering and online ordering from primary school canteens in terms of menu, usage and lunch order characteristics. Design: A cross-sectional study. Setting: New South Wales (NSW) primary schools that offered both paper bag and online canteen ordering. Participants: Students (aged 5-12 years) with a lunch order on the day of the observation. Results: Across the six school canteens, 59-90 % of all available items were listed on both the online and paper menus, with no significant differences in the nutritional quality ('Everyday'/'Occasional') or nutritional content (kJ/saturated fat/sugar/sodium) of menu items. In total, 387 student lunch orders were placed, containing 776 menu items. Most orders (68 %) were placed online. There were no significant differences between order modality in the quantity of items ordered or the cost of orders, or the nutritional quality of orders based on the classification system of the NSW Healthy School Canteen Strategy ('Everyday'/'Occasional'). However, nutritional analysis revealed that paper bag orders contained 222 fewer kJ than online orders (P = 0·001), 0·65 g less saturated fat (P = 0·04) and 4·7 g less sugar (P < 0·001). Conclusions: Online canteens are commonly used to order canteen lunches for primary school children. This is the first study to investigate differences between traditional paper bag ordering and online ordering in this setting. Given the rapid increase in the use of online ordering systems in schools and other food settings and their potential to deliver public health nutrition interventions, additional research is warranted to further investigate differences in ordering modalities.

Unhealthy dietary patterns in adolescence are associated with an increased risk of future chronic disease. This study aimed to assess online canteen lunch purchases made by high school students to identify: (1) the nutrient composition of purchases (energy, saturated fat, sugar, sodium, percent energy from saturated fat and total sugar); (2) the proportion of items classified as healthier (¿Everyday¿) and less healthy (¿Occasional¿ or ¿Should not be sold¿) according to the New South Wales Healthy Canteen Strategy; (3) the frequency of purchases by product type (e.g., salty snacks), their classification and nutrient composition; and (4) associations between student characteristics and the nutrient composition and classification of purchases. The average order contained 2075 kJ of energy, 6.4 g of saturated fat, 18.4 g of sugar and 795 mg of sodium. Less healthy (¿Occasional¿ and ¿Should not be sold¿) items combined accounted for 56% of purchases. The most frequently purchased products were burgers and crumbed/coated foods. Students in higher grades purchased a significantly higher mean percent of ¿Everyday¿ items, compared to students in grades 7 or 8. The majority of high school student purchases were less healthy (¿Occasional¿ or ¿Should not be sold¿) items, warranting further investigation of factors influencing online canteen purchasing behaviour in this setting.

Few online food ordering systems provide tailored dietary feedback to consumers, despite suggested benefits. The study aim was to determine the effect of providing tailored feedback on the healthiness of students¿ lunch orders from a school canteen online ordering system. A cluster randomized controlled trial with ten government primary schools in New South Wales, Australia was conducted. Consenting schools that used an online canteen provider (¿Flexischools¿) were randomized to either: a graph and prompt showing the proportion of ¿everyday¿ foods selected or a standard online ordering system. Students with an online lunch order during baseline data collection were included (n = 2200 students; n = 7604 orders). Primary outcomes were the proportion of foods classified as ¿everyday¿ or ¿caution¿. Secondary outcomes included: mean energy, saturated fat, sugar, and sodium content. There was no difference over time between groups on the proportion of ¿everyday¿ (OR 0.99; p = 0.88) or ¿caution¿ items purchased (OR 1.17; p = 0.45). There was a significant difference between groups for average energy content (mean difference 51 kJ; p-0.02), with both groups decreasing. There was no difference in the saturated fat, sugar, or sodium content. Tailored feedback did not impact the proportion of ¿everyday¿ or ¿caution¿ foods or the nutritional quality of online canteen orders. Future research should explore whether additional strategies and specific feedback formats can promote healthy purchasing decisions.

There has been a proliferation of digital health interventions (DHIs) targeting dietary in-take. Despite their potential, the effectiveness of DHIs are thought to be dependent, in part, on user engagement. However, the relationship between engagement and the effectiveness of dietary DHIs is not well understood. The aim of this review is to describe the association between DHI engagement and dietary intake. A systematic search of four electronic databases and grey literature for records published before December 2019 was conducted. Studies were eligible if they examined a quantitative association between objective measures of engagement with a DHI (subjective experience or usage) and measures of dietary intake in adults (aged = 18 years). From 10,653 citations, seven studies were included. Five studies included usage measures of engagement and two examined subjective experiences. Narrative synthesis, using vote counting, found mixed evidence of an association with usage measures (5 of 12 associations indicated a positive relationship, 7 were in-conclusive) and no evidence regarding an association with subjective experience (both studies were inconclusive). The findings provide early evidence supporting an association between measures of usage and dietary intake; however, this was inconsistent. Further research examining the association between DHI engagement and dietary intake is warranted.

Little is known about the long-term impact of telephone-based interventions to improve child diet. This trial aimed to assess the long-term effectiveness (after 5 years) of a telephone-based parent intervention in increasing children¿s fruit and vegetable consumption. Parents of 3¿5 year olds were recruited from 30 Australian preschools to participate in a cluster randomised controlled trial. Intervention parents received four, weekly, 30-min support calls aimed at modifying the home food environment. Control parents received printed materials. Consumption was assessed using the Fruit and Vegetable subscale of the Children¿s Dietary Questionnaire (F&V-CDQ) (children) and daily servings of fruit and vegetables (children and parents) via parent telephone interview. Of the 394 parents who completed baseline, 57% (99 intervention, 127 control) completed follow-up. After 5-years, higher intervention F&V-CDQ scores, bordering on significance, were found in complete-case (+1.1, p = 0.06) and sensitivity analyses (+1.1, p = 0.06). There was no difference in parent or child consumption of daily fruit servings. Complete-case analysis indicated significantly higher consumption of child vegetable servings (+0.5 servings; p = 0.02), which was not significant in sensitivity analysis (+0.5 servings; p = 0.10). This telephone-based parent intervention targeting the family food environment may yield promising improvements in child fruit and vegetable consumption over a 5-year period.

Although it is recommended that childcare centers provide foods consistent with dietary guidelines, the impact of implementing sector-specific guidelines on child outcomes is largely unknown. Objectives: This study aims to examine the impact of a web-based program and support to implement dietary guidelines in childcare centers on children's 1) diet; 2) BMI z scores; and 3) child health-related quality of life (HRQoL). Methods: This study was a cluster-randomized controlled trial utilizing a Type-3 Hybrid implementation-effectiveness design conducted between October 2016 and March 2018. This study reports on child outcomes. Fifty-four childcare centers in New South Wales, Australia were randomly assigned to the intervention (a web-based menu-planning tool and support) or control group (usual care). The intervention was designed to address barriers and enablers to dietary guideline implementation according to the Theoretical Domains Framework. A quota of 35 consenting childcare centers undertook child-level evaluation of dietary intake where 522 parents consented to completing =1 component of data collection for their child. Child consumption of core and discretionary (unhealthy) foods while in care was assessed via dietary observations by blinded research assistants, childcare diet quality was assessed via educator-completed questionnaires, BMI z scores were assessed via measured weight and height, and child HRQoL was assessed via parent report at baseline and 12-mo follow-up. Results: There was a significant increase in mean child consumption of fruit (0.39 servings; 95% CI: 0.12, 0.65 servings) and dairy foods (0.38 servings; 95% CI: 0.19, 0.57 servings) and a significant reduction in consumption of discretionary foods (-0.40 servings; 95% CI: -0.64, -0.16 servings) in care in the intervention group, relative to control at 12-mo follow-up. No significant differences were observed in diet quality, BMI z scores, or HRQoL. Conclusions: A web-based intervention to support planning of childcare menus consistent with dietary guidelines can improve child consumption of healthier foods in daycare. This trial was registered at www.anzctr.org.au as ACTRN12616000974404.

The study aimed to compare the effectiveness of a suite of implementation strategies of varying intensities on centre-based childcare service implementation of nutrition guideline recommendations at 12-month follow-up. A six-month three-arm parallel group randomised controlled trial was undertaken with 69 services, randomised to one of three arms: high-intensity strategies (executive support; group face-to-face training; provision of resources; multiple rounds of audit and feedback; ongoing face-to-face and phone support); low-intensity strategies (group face-to-face training; provision of resources; single round of audit and feedback); or usual care control. Across all study arms, only three high-intensity services were compliant with overall nutrition guidelines. A significant group interaction was found between the three arms for compliance with individual food groups. Relative to control, a significantly greater proportion of low-intensity services were compliant with dairy, and a significantly greater proportion of high-intensity services were compliant with fruit, vegetables, dairy, breads and cereals, and discretionary foods. No significant differences between the high-and low-intensity for individual food group compliance were found. High-intensity implementation strategies may be effective in supporting childcare service implementation of individual food group recommendations. Further research is warranted to identify strategies effective in increasing overall nutrition compliance.

Background: Manipulating the position of food items within the physical food environment has consistently been found to influence item selection. However, the extent to which this strategy is effective in an online food environment is unknown. Objective: This study investigated whether an intervention to position fruit and vegetable snack items as the first and last menu items in an online school canteen ordering system increased the selection of those items. It was hypothesized that at follow-up, a higher proportion of online lunch orders in intervention schools would contain the target items (fruit and vegetable snacks) in comparison to control schools. Design: Six primary schools in New South Wales, Australia, were recruited to a clustered randomized controlled trial conducted over an 8-wk period. Intervention schools received a redesigned menu where the target items were positioned first and last on the online menu. Control schools received no change to their online menu. Results: During the baseline period 1938 students (1203 intervention, 735 control) placed at least one online lunch order and were included in the study, with 16,109 orders placed throughout the study. There was no significant difference between groups over time in the proportion of orders that contained a ¿Fruit and Veggie Snack¿ item (OR = 1.136 [95% CI: 0.791, 1.632] P = 0.490). Conclusions: Evidence from this large trial with robust study design and objectively collected data suggests that positioning fruit and vegetable snack items first and last within an online canteen menu does not increase the selection of these items. Further research is warranted to confirm this finding with other target menu items (e.g., treats) and across other purchasing contexts and online food ordering platforms. This trial was registered at the Australian New Zealand Clinical Trials Registry, http://www.anzctr.org.au/ as ACTRN12616001520426.

Suboptimal vegetable and fruit consumption by young children is common. Identifying predictors of vegetable and fruit intakes is important for informing strategies to promote sufficient intakes of these foods from early life. The aim of the present study was to examine predictors of toddlers¿ vegetable and fruit intakes at age 18 months. This study involved secondary analysis of data from 361 child-mother dyads participating in the Melbourne Infant Feeding, Activity and Nutrition Trial in 2008¿2010 at child ages four, nine and 18 months. Children's vegetable and fruit intakes were assessed at age 18 months using multiple 24-h dietary recalls. Data on potential predictor measures were collected via parent-completed questionnaires when children were four or nine months of age. Bivariate and multivariable linear regression models were used to test associations between children's average daily vegetable or fruit intake and potential predictors controlling for treatment arm and clustering by parent group. Multivariable models also controlled for covariates and potential confounders. Home availability of vegetables at age nine months was found to predict children's vegetable intake at age 18 months and remained significant (ß = 20.19, 95% CI:7.23, 33.15, p = 0.003)in the multivariable model. Children's average daily fruit intake at age 18 months was predicted by maternal education at child age four months and the availability of fruits in their home at child age nine months. Maternal education remained significant (ß = 30.83, 95% CI:12.17, 49.48, p = 0.002)in the multivariable model. Strategies to promote adequate vegetable and fruit intakes among young children should address known barriers to the availability of vegetables and fruits in the home from early in life. Additionally, messages encouraging fruit consumption may need to be tailored to mothers with lower levels of education.

Objective: To assess the nutritional quality of student canteen purchases at recess and lunch, including: (i) the mean energy (kilojoules), saturated fat (grams), total sugar (grams) and Na (milligrams) and percentage of energy from saturated fat and total sugar; and (ii) the proportion and types of foods purchased that are healthier (green) and less healthy (amber/red) according to a state school canteen policy.Design: A cross-sectional study of student canteen food and beverage recess and lunch purchases.Setting: Twenty-six randomly selected government primary schools that were non-compliant with a state school canteen policy from a region of New South Wales, Australia, were approached to participate.Participants: Students (aged 5-12 years) of participating schools.Results: Eighteen schools (69 %) consented to participate. On average students' recess purchases contained 571·2 kJ energy, 1·6 g saturated fat, 11·6 g total sugar and 132·4 mg Na with 10·0 % of energy from saturated fat and 37·8 % of energy from total sugar. Students' lunch purchases contained 685·4 kJ energy, 1·8 g saturated fat, 12·7 g total sugar and 151·4 mg Na with 9·5 % of energy from saturated fat and 31·8 % of energy from total sugar. Less healthy items represented 72 and 76 % of all items purchased at recess and lunch, respectively, with 'savoury snacks' and 'sugar-sweetened ice blocks and slushies' being the most common recess and lunch purchases, respectively.Conclusions: There is considerable scope to improve the nutritional quality of student purchases from primary-school canteens, with a high percentage of energy from total sugar. Future research is required to identify effective strategies to enhance compliance with canteen policies and support the purchase of healthier foods from school canteens.

Issue addressed: School-based nutrition policies can have a positive effect on the school food environment. The primary aim of this study was to assess the primary school adherence to a mandatory state-wide healthy canteen policy 12¿months after an effective multi-strategic implementation intervention concluded. Methods: Primary schools were randomised to (a) a 12-14¿months multi-strategic intervention or (b) no-intervention (control). The intervention aimed to improve implementation of a state-wide canteen policy by encouraging schools to remove unhealthy food and beverages (classified as ¿¿red¿¿ or ¿¿banned¿¿) from canteen menus and replace with healthy items (classified as ¿¿green¿¿). No implementation support was provided to either group by the research team between the 12 and 24¿months data collection period. Results: Seventy schools participated, of which 56 schools were assessed at 24-month follow-up. Intervention schools were less likely to have a menu which contained ¿¿red/banned¿¿ items at 24-month follow-up (RR¿=¿2.28; 95% CI: 1.18-4.40; P¿=¿0.01). Intervention schools, however, were not more likely than controls to have a menu which contained >50% ¿¿green¿¿ items at 24-month follow-up (RR¿=¿1.29; 95% CI: 0.98-1.70; P¿=¿0.10). Intervention schools were more likely to adhere to both policy components (no red/banned items and >50% green items on the menu) than control schools (RR¿=¿2.61; 95% CI: 1.29-5.29; P¿=¿0.006). Among intervention schools that were fully adherent to the policy following implementation support (12-month post baseline), all were also adherent at the 24-month follow-up. Conclusion: The intervention was effective in achieving long-term school adherence to a state-wide canteen policy at 24-month follow-up. So what?: The findings suggest that sustained improvements in implementation of school nutrition policies is possible following a period (12¿months) of comprehensive implementation support.

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.

Objective To (i) describe the proportion of foods and beverages available on school canteen menus classified as having high ('green'), moderate ('amber') or low ('red') nutritional value; (ii) describe the proportion of these items purchased by students; and (iii) examine the association between food and beverage availability on school canteen menus and food and beverage purchasing by students.Design A cross-sectional study was conducted as part of a larger randomised controlled trial (RCT).Setting A nested sample of fifty randomly selected government schools from the Hunter New England region of New South Wales, Australia, who had participated in an RCT of an intervention to improve the availability of healthy foods sold from school canteens, was approached to participate.Subjects School principals, canteen managers and students.Results The average proportion of green, amber and red items available on menus was 47·9, 47·4 and 4·7 %, respectively. The average proportion of green, amber and red items purchased by students was 30·1, 61·8 and 8·1 %, respectively. There was a significant positive relationship between the availability and purchasing of green (R 2=0·66), amber (R 2=0·57) and red menu items (R 2=0·61). In each case, a 1 % increase in the availability of items in these categories was associated with a 1·21, 1·35 and 1·67 % increase in purchasing of items of high, moderate and low nutritional value, respectively.Conclusions The findings provide support for school-based policies to improve the relative availability of healthy foods for sale in these settings.

Background Front-of-pack graphical nutritional rating of products is becoming an important strategy in many countries to improve healthy food purchases by consumers. Evidence of the effectiveness of such on facilitating healthy food choices by school food service providers has not been reported. The primary aim of the study was to assess the impact of providing front-of-pack nutritional rating information on school canteen managers¿ likely food selections. Secondary outcomes were canteen manager awareness, attitudes and reported barriers to using the front-of-pack information. Methods A randomised controlled trial involving primary school canteen managers was conducted in a single region in New South Wales, Australia. Eligible participants were randomised to an intervention or control group and asked in a telephone interview which of 12 common food products sold in school canteens they would sell. Both groups received product name and brand information. The intervention group also received information regarding the nutritional rating of products. Results Canteen managers in the intervention group were significantly more likely than those in the control group to indicate they would sell three of the six ¿healthier¿ products (p = 0.036, 0.005, 0.009). There was no difference between groups in the likelihood of making available for sale any of the six ¿less healthy¿ products. The majority of canteen managers who had heard of a product nutritional rating system agreed that it was helpful in identifying ¿healthier¿ foods (88%, n = 31). Conclusions The inclusion of product nutritional rating information has the potential to improve the availability of some ¿healthier¿ items on canteen menus and contribute to improving child dietary intake. Further research is required to determine whether the use of product nutritional rating information actually makes a difference to canteen manager choices.

Children attending centre based childcare services consume as much as two thirds of their daily dietary requirements while in care. However, such services often fail to provide foods that are consistent with guideline recommendations. Developing strategies to improve childcare service adherence to menu dietary guidelines requires a comprehensive understanding of factors that may impede or promote implementation. The primary aim of this systematic review is to describe factors (barriers and facilitators) that may influence the implementation of menu dietary guidelines regarding food provision in centre-based childcare services and to map these factors to a theoretical framework. Over 7000 citations were identified from all sources. Duplicate abstracts were removed and selection criteria applied. Twelve studies (1994¿2015) were included in the review. Dual data extraction was conducted and the reported factors were synthesised using the theoretical domains framework (TDF). Barriers and facilitators identified in qualitative studies were classified into 8 and 10 of the 14 TDF domains. Barriers and facilitators reported in quantitative studies covered 6 and 3 TDF domains respectively. The most common domain of which both barriers and facilitators to the implementation of menu dietary guidelines were identified was ¿environmental context and resources¿. This is the first study that comprehensively assesses literature to identify factors that influence the implementation of menu dietary guidelines in childcare services utilising a theoretical framework. Findings provide guidance to support researchers and policy makers design strategies to improve menu dietary guideline implementation and, as such have the potential to improve food provision in care.

Issue addressed: This study of primary school principals assessed the awareness, use, barriers to use and acceptability of online canteens. Methods: A telephone survey of 123 primary school principals within the Hunter New England Region of New South Wales, Australia was conducted from September 2014 to November 2014. Results: Fifty-six percent of principals were aware of the existence of online canteens, with 8% having implemented such a system, and 38% likely to do so in the future. Medium/large schools were more likely to be aware of or to use online canteens, however there were no differences in awareness or use in relation to school rurality or socioeconomic advantage. Principals cited parent internet access as the most commonly identified perceived barrier to online canteen use, and the majority of principals (71-93%) agreed that it would be acceptable to implement a range of consumer behaviour strategies via an online canteen. Conclusions: Study findings suggest that despite relatively low levels of current use, online canteens have the potential to reach a large proportion of school communities in the future, across geographical and socioeconomic divides, and that the nutrition interventions which they have the capacity to deliver are considered acceptable to school principals. So what? Online canteens may represent an opportunity to deliver nutrition interventions to school communities. Future research should examine the feasibility and potential effectiveness of interventions delivered via this modality.

Issue addressed In order to assess the impact of healthy school canteen policies on food availability for students, valid methods of measuring compliance are needed that can be applied at scale. The aim of this study is to assess the validity and direct cost of four methods to assess policy compliance: 1) principal and 2) canteen manager self-report via a computer-assisted telephone interview; and 3) comprehensive and 4) quick menu audits by dietitians, compared with observations. Methods A cross-sectional study took place in the Hunter region of NSW, Australia, in a sample of 38 primary schools that had previously participated in a randomised controlled trial to improve healthy canteen policy compliance. Policy compliance was assessed using the four methods specified above. Percentage agreement, kappa, sensitivity and specificity compared with observations was calculated together with the direct time taken and costs of each method. Indirect costs (including set-up costs) for all measures have not been included. Results Agreement with observations was substantial for the quick menu audit (kappa=0.68), and moderate for the comprehensive menu audit (kappa=0.42). Principal and canteen manager self-report resulted in poor agreement and low specificity with the gold standard. The self-reported measures had the lowest cost, followed by the quick menu audit and lastly the comprehensive menu audit. Conclusion The quick menu audit represents a valid and potentially low-cost method of supporting policy implementation at scale. So what? This study demonstrates that a quick menu audit represents a valid measure of undertaking assessment of school canteen policy compliance at a population level.

Background: The home food environment can influence the development of dietary behaviours in children, and interventions that modify characteristics of the home food environment have been shown to increase children's fruit and vegetable consumption. However to date, interventions to increase children's fruit and vegetable consumption have generally produced only modest effects. Mediation analysis can help in the design of more efficient and effective interventions by identifying the mechanisms through which interventions have an effect. This study aimed to identify characteristics of the home food environment that mediated immediate and sustained increases in children's fruit and vegetable consumption following the 4-week Healthy Habits telephone-based parent intervention. Method: Analysis was conducted using 2-month (immediate) and 12-month (sustained) follow-up data from a cluster randomised control trial of a home food environment intervention to increase the fruit and vegetable consumption of preschool children. Using recursive path analysis, a series of mediation models were created to investigate the direct and indirect effects of immediate and sustained changes to characteristics of the home food environment (fruit and vegetable availability, accessibility, parent intake, parent providing behaviour, role-modelling, mealtime eating practices, child feeding strategies, and pressure to eat), on the change in children's fruit and vegetable consumption. Results: Of the 394 participants in the randomised trial, 357 and 329 completed the 2- and 12-month follow-up respectively. The final mediation model suggests that the effect of the intervention on the children's fruit and vegetable consumption was mediated by parent fruit and vegetable intake and parent provision of these foods at both 2- and 12-month follow-up. Conclusion: Analysis of data from the Healthy Habits trial suggests that two environmental variables (parental intake and parent providing) mediate the immediate and sustained effect of the intervention, and it is recommended these variables be targeted in subsequent home food environment interventions to bring about immediate and sustained changes in child fruit and vegetable intake.

Many early childhood education and care (ECEC) services fail to implement recommended policies and practices supportive of healthy eating and physical activity. The purpose of this study was to assess whether certain theoretically-based factors are associated with implementation of healthy eating and physical activity policies and practices in a sample of ECEC services. A cross-sectional survey was conducted with Service Managers of ECEC services. The survey assessed the operational characteristics, policy, and practice implementation, and 13 factors were suggested by Damschroder¿s Consolidated Framework for Implementation Research to impede or promote implementation. Logistic regression analyses found a significant association between implementation factor score and full implementation (OR 1.38; 95% CI 1.18¿1.61; p = <0.01), indicating that for every one point increase in implementation score, ECEC services were 38¿% more likely to be fully implementing the policies and practices. The findings highlight the opportunities for improving implementation of obesity prevention interventions in this setting by developing interventions that address such factors.

Introduction Schools represent a valuable setting for interventions to improve children's diets, as they offer structured opportunities for ongoing intervention. Modifications to the school food environment can increase purchasing of healthier foods and improve children's diets. This study examines the availability of healthy food and drinks, implementation of pricing and promotion strategies in Australian primary school canteens, and whether these varied by school characteristics. Methods In 2012 and 2013, canteen managers of primary schools in the Hunter New England region of New South Wales reported via telephone interview the pricing and promotion strategies implemented in their canteens to encourage healthier food and drink purchases. A standardized audit of canteen menus was performed to assess the availability of healthy options. Data were analyzed in 2014. Results Overall, 203 (79%) canteen managers completed the telephone interview and 170 provided menus. Twenty-nine percent of schools had menus that primarily consisted of healthier food and drinks, and 11% did not sell unhealthy foods. Less than half reported including only healthy foods in meal deals (25%), labeling menus (43%), and having a comprehensive canteen policy (22%). A significantly larger proportion of schools in high socioeconomic areas (OR=3.0) and large schools (OR=4.4) had primarily healthy options on their menus. School size and being a Government school were significantly associated with implementation of some pricing and promotion strategies. Conclusions There is a need to monitor canteen environments to inform policy development and research. Future implementation research to improve the food environments of disadvantaged schools in particular is warranted.

Introduction: A number of jurisdictions internationally have policies requiring schools to implement healthy canteens. However, many schools have not implemented such policies. One reason for this isthat current support interventions cannot feasibly be delivered to large numbers of schools. A promising solution to support population-wide implementation of healthy canteen practices is audit and feedback. The effectiveness of this strategy has, however, not previously been assessed in school canteens. This study aims to assess the effectiveness and cost-effectiveness of an audit and feedback intervention, delivered by telephone and email, in increasing the number of school canteens that have menus complying with a government healthy-canteen policy. Methods and analysis: Seventy-two schools, across the Hunter New England Local Health District in New South Wales Australia, will be randomised to receive the multicomponent audit and feedback implementation intervention or usual support. The intervention will consist of between two and four canteen menu audits over 12 months. Each menu audit will be followed by two modes of feedback: a written feedback report and a verbal feedback/support via telephone. Primary outcomes, assessed by dieticians blind to group status and as recommended by the Fresh Tastes @ School policy, are: (1) the proportion of schools with a canteen menu containing foods or beverages restricted for sale, and; (2) the proportion of schools that have a menu which contains more than 50% of foods classified as healthy canteen items. Secondary outcomes are: the proportion of menu items in each category ('red', 'amber' and 'green'), canteen profitability and cost-effectiveness. Ethics and dissemination: Ethical approval has been obtained by from the Hunter New England Human Research Ethics Committee and the University of Newcastle Human Research Ethics Committee. The findings will be disseminated in usual forums, including peer-reviewed publication and conference presentations.

Background: Overweight and obesity is a significant public health problem that impacts a large number of children globally. Supporting childcare centers to deliver healthy eating and physical activity-promoting policies and practices is a recommended strategy for obesity prevention, given that such services provide access to a substantial proportion of children during a key developmental period. Electronic Web-based interventions represent a novel way to support childcare service providers to implement such policies and practices. Objective: This study aimed to assess: (1) childcare centers' current use of technology, (2) factors associated with intention to use electronic Web-based interventions, and (3) Web-based features that managers rated as useful to support staff with implementing healthy eating and physical activity-promoting policies and practices. Methods: A computer-Assisted telephone interview (CATI) was conducted with service managers from long day care centers and preschools. The CATI assessed the following: (1) childcare center characteristics, (2) childcare centers' use of electronic devices, (3) intention to use a hypothetical electronic Web-based program-Assessed using the Technology Acceptance Model (TAM) with ratings between 1 (strongly disagree) and 7 (strongly agree), and (4) features rated as useful to include in a Web-based program. Results: Overall, 214 service centers out of 277 (77.3%) consented to participate. All service centers except 2 reported using computers (212/214, 99.1%), whereas 40.2% (86/214) used portable tablets. A total of 71.9% (151/210) of childcare service managers reported a score of 6 or more for intention to use a hypothetical electronic Web-based program. In a multivariable logistic regression analysis, intention to use the program was significantly associated with perceived ease of use (P=.002, odds ratio [OR] 3.9, 95% CI 1.6-9.2) and perceived usefulness (P<.001, OR 28,95% CI 8.0-95.2). Features reported by service managers as useful or very useful for a Web-based program included decision-support tools to support staff with menu planning (117/129, 90.7%), links to relevant resources (212/212, 100%), updated information on guidelines (208/212, 98.1%), and feedback regarding childcare center performance in relation to other childcare centers (212/212, 100%). Conclusions: Childcare service managers reported high intention to use a Web-based program and identified several useful features to support staff to implement healthy eating and physical activity policies and practices. Further descriptive and intervention research examining the development and use of such a program to support childcare centers with the implementation of healthy eating and physical activity-promoting policies and practices is warranted.

Childcare services represent a valuable obesity prevention opportunity, providing access to a large portion of children at a vital point in their development. Few rigorously validated measures exist to measure healthy eating and physical activity policies and practices in this setting, and no such measures exist that are specific to the childcare setting in Australia. Methods. This was a cross sectional study, comparing two measures (pen and paper survey and observation) of healthy eating and physical activity policies and practices in childcare services. Research assistants attended consenting childcare services (n = 42) across the Hunter region of New South Wales, Australia and observed practices for one day. Nominated Supervisors and Room Leaders of the service also completed a pen and paper survey during the day of observation. Kappa statistics and proportion agreement were calculated for a total of 43 items relating to healthy eating and physical activity policies and practices. Results: Agreement ranged from 38%-100%. Fifty one percent of items showed agreement of greater than or equal to 80%. Items assessing the frequency with which staff joined in active play with children reported the lowest percent agreement, while items assessing availability of beverages such as juice, milk and cordial, as well as the provision of foods such as popcorn, pretzels and sweet biscuits, reported the highest percent agreement. Kappa scores ranged from -0.06 (poor agreement) to 1 (perfect agreement). Of the 43 items assessed, 27 were found to have moderate or greater agreement. Conclusions: The study found that Nominated Supervisors and Room Leaders were able to accurately report on a number of healthy eating and physical activity policies and practices. Items assessing healthy eating practices tended to have higher kappa scores than those assessing physical activity related policies or practices. The tool represents a useful instrument for public health researchers and policy makers working in this setting. © 2014Dodds et al.; licensee BioMed Central Ltd.

Background: Telephone-based interventions can be effective in increasing child fruit and vegetable intake in the short term (<6 mo). The long-term efficacy of such interventions, however, is unknown. Objectives: The primary aim of this study was to determine whether the short-term (<6 mo) impact of a telephone-based intervention on children's fruit and vegetable intake was sustained over a longer term. A secondary aim of the study was to assess the long-term impact of the intervention on the intake of foods high in fat, salt, or sugar (noncore foods). Design: The study used a cluster randomized controlled trial design. Parents were recruited from Australian preschools between February and August 2010 and allocated to receive an intervention consisting of print materials and 4 telephone-counseling calls delivered over 1 mo or to a print information-only control group. The primary endpoint for the trial was the 18-mo postbaseline follow-up. Linear regression models were used to assess between-group differences in child consumption of fruit and vegetables and noncore foods by subscales of the Children's Dietary Questionnaire. Results: Fruit and vegetable subscale scores were significantly higher, indicating greater child fruit and vegetable intake, among children in the intervention group at the 12-mo (16.77 compared with 14.89; P < 0.01) but not the 18-mo (15.98 compared with 16.82; P = 0.14) follow-up. There were no significant differences between groups at either of the follow-up periods in the noncore food subscale score. Conclusion: Further research to identify effective maintenance strategies is required to maximize the benefits of telephone-based interventions on child diet.

Issue addressed: School-based programs targeting the prevention of tobacco use are a key strategy for reducing the overall tobacco-related mortality and morbidity in the community. While substantial research investment has resulted in the identification of various effective tobacco prevention interventions in schools, this research investment will not result in public health benefits, unless effectively disseminated and implemented. This rapid review aimed to identify effective implementation or dissemination interventions, targeting the adoption of school-based tobacco prevention programs. Methods: A systematic search was conducted to identify published systematic reviews that examined the effectiveness of implementation and dissemination strategies for facilitating the adoption of tobacco policies or programs in schools from 1992 to 2012. Results: The search yielded 1028 results, with one relevant systematic review being identified. The review included two controlled studies examining the implementation and dissemination of tobacco prevention programs and guidelines. The two randomised trials examined the delivery of active face-to-face training to implement a school-based curriculum compared with video-delivered or mail-based training. Improvements in the implementation of the programs were reported for the face-to-face training arm in both trials. Conclusions: Little rigorous evidence exists to guide the implementation and dissemination of tobacco prevention programs in schools. So what?: Few systematic reviews exist to inform the implementation of evidence-based tobacco prevention programs in schools. In the absence of a strong evidence base, health care policymakers and practitioners may need to draw on setting-based frameworks or parallel evidence from other settings to design strategies to facilitate the adoption of tobacco prevention initiatives.

Issue addressed: Centre-based childcare services represent a promising setting to target the prevention of excessive weight gain in preschool-aged children. Staff training is a key component of multi-strategy interventions to improve implementation of effective physical activity and nutrition promoting practices for obesity prevention in childcare services. This randomised controlled trial aimed to examine whether an active telephone-based strategy to invite childcare-service staff to attend a training workshop was effective in increasing the proportion of services with staff attending training, compared with a passive strategy. Methods: Services were randomised to an active telephone-based or a passive-recruitment strategy. Those in the active arm received an email invitation and one to three follow-up phone calls, whereas services in the passive arm were informed of the availability of training only via newsletters. The proportion of services with staff attending the training workshop was compared between the two arms. Results: One hundred and twenty-eight services were included in this study. A significantly larger proportion (52%) of services in the active arm compared with those in the passive-strategy arm (3.1%) attended training (d.f.=1, ¿2=34.3; P<0.001). Conclusions: An active, telephone-based recruitment strategy significantly increased the proportion of childcare services with staff attending training. Further strategies to improve staff attendance at training need to be identified and implemented. So what? Active-recruitment strategies including follow-up telephone calls should be utilised to invite staff to participate in training, in order to maximise the use of training as an implementation strategy for obesity prevention in childcare services. © 2013 Australian Health Promotion Association.
