Background: There is a large number of research studies about the prevention of non-communicable diseases (NCD), with findings taking several years to be translated into practice. One reason for this lack of translation is a limited understanding of how to best disseminate NCD research findings to user-groups in a way that is salient and useful. An understanding of barriers and facilitators to dissemination is key to informing the development of strategies to increase dissemination. Therefore, this review aims to identify and synthesise the barriers and facilitators to dissemination of NCD research findings. Methods: A mixed studies systematic review was performed following JBI (formerly known as Joanna Briggs Institute) methodology. The search included articles from January 2000 until May 2021. We conducted a comprehensive search of bibliographic and grey literature of five databases to identify eligible studies. Studies were included if they involved end-users of public health research that were decision-makers in their setting and examined barriers/facilitators to disseminating research findings. Two pairs of reviewers mapped data from included studies against the Framework of Knowledge Translation (FKT) and used a convergent approach to synthesise the data. Results: The database search yielded 27,192 reports. Following screening and full text review, 15 studies (ten qualitative, one quantitative and four mixed methods) were included. Studies were conducted in 12 mostly high-income countries, with a total of 871 participants. We identified 12 barriers and 14 facilitators mapped to five elements of the FKT. Barriers related to: (i) the user-group (n = 3) such as not perceiving health as important and (ii) the dissemination strategies (n = 3) such as lack of understanding of content of guidelines. Several facilitators related to dissemination strategies (n = 5) such as using different channels of communication. Facilitators also related to the user-group (n = 4) such as the user-groups' interest in health and research. Conclusion: Researchers and government organisations should consider these factors when identifying ways to disseminate research findings to decision-maker audiences. Future research should aim to build the evidence base on different strategies to overcome these barriers. Systematic review registration: The protocol of this review was deposited in Open Science Framework (https://doi.org/10.17605/OSF.IO/5QSGD).

Early childhood education and care (ECEC) services are a key setting to support improvements in the physical activity of young children. This umbrella review gathered and synthesised systematic review evidence of the effectiveness of interventions in the ECEC setting on the physical activity levels of children aged 0¿6. We also mapped the current evidence to the existing ECEC sector-specific physical activity practice recommendations. Five electronic databases were searched to identify systematic reviews that evaluated the impact of any ECEC-based interventions on the physical activity levels (e.g., moderate-to-vigorous physical activity, total physical activity) of children aged 0¿6. One reviewer extracted data on intervention effectiveness and quality of the reviews, checked by a second reviewer. Ten reviews were included. Overall, the majority of the reviews found interventions delivered in ECEC improved child physical activity. Across reviews, the impact of six intervention strategies were identified, mapped to four (of eight) broad recommendations (i.e., providing opportunity, offering educator training, educators promoting the benefits of physical activity, creating a physical activity-promoting environment). The impact of the majority of recommendations, however, did not have systematic review evidence. Further investigation of the effectiveness of ECEC-based physical activity strategies is required to demonstrate support for the existing recommended practices.

Background: There is significant opportunity to improve the nutritional quality of foods packed in children's school lunchboxes. Interventions that are effective and scalable targeting the school and home environment are therefore warranted. Objective: This study aimed to assess the effectiveness of a multicomponent, mobile health-based intervention, SWAP IT, in reducing the energy contribution of discretionary (ie, less healthy) foods and drinks packed for children to consume at school. Methods: A type I effectiveness-implementation hybrid cluster randomized controlled trial was conducted in 32 primary schools located across 3 local health districts in New South Wales, Australia, to compare the effects of a 6-month intervention targeting foods packed in children's lunchboxes with those of a usual care control. Primary schools were eligible if they were not participating in other nutrition studies and used the required school communication app. The Behaviour Change Wheel was used to co-design the multicomponent SWAP IT intervention, which consisted of the following: school lunchbox nutrition guidelines, curriculum lessons, information pushed to parents digitally via an existing school communication app, and additional parent resources to address common barriers to packing healthy lunchboxes. The primary outcome, mean energy (kilojoules) content of discretionary lunchbox foods and drinks packed in lunchboxes, was measured via observation using a validated school food checklist at baseline (May 2019) and at 6-month follow-up (October 2019). Additional secondary outcomes included mean lunchbox energy from discretionary foods consumed, mean total lunchbox energy packed and consumed, mean energy content of core lunchbox foods packed and consumed, and percentage of lunchbox energy from discretionary and core foods, all of which were also measured via observation using a validated school food checklist. Measures of school engagement, consumption of discretionary foods outside of school hours, and lunchbox cost were also collected at baseline and at 6-month follow-up. Data were analyzed via hierarchical linear regression models, with controlling for clustering, socioeconomic status, and remoteness. Results: A total of 3022 (3022/7212, 41.90%) students consented to participate in the evaluation (mean age 7.8 years; 1487/3022, 49.22% girls). There were significant reductions between the intervention and control groups in the primary trial outcome, mean energy (kilojoules) content of discretionary foods packed in lunchboxes (-117.26 kJ; 95% CI -195.59 to -39.83; P=.003). Relative to the control, the intervention also significantly reduced secondary outcomes regarding the mean total lunchbox energy (kilojoules) packed (-88.38 kJ; 95% CI -172.84 to -3.92; P=.04) and consumed (-117.17 kJ; 95% CI -233.72 to -0.62; P=.05). There was no significant difference between groups in measures of student engagement, consumption of discretionary foods outside of school hours, or cost of foods packed in children's lunchboxes. Conclusions: The SWAP IT intervention was effective in reducing the energy content of foods packed for and consumed by primary school-aged children at school. Dissemination of the SWAP IT program at a population level has the potential to influence a significant proportion of primary school-aged children, impacting weight status and associated health care costs.

Abstract Objective: The aim of the study was to assess the impact of different lunchbox messages on parents' intention to pack a healthy lunchbox. Design: This study employed an experimental design. Setting: A series of messages were developed to align with the six constructs of the Health Belief Model. Messages were also developed that were (and were not) personalised and varied based on the source of the information provided (university, school, dietitian and health promotion service). During a telephone survey, participants were read the content of each message and asked about their intention to pack a healthy lunchbox. Participants: Parents of primary school-aged children were randomised to receive different messages to encourage the packing of healthy lunchboxes. Results: The study was completed by 511 parents. Linear mixed regression analyses identified significant differences (P < 0·05) in intention scores between variant messages targeting the same behavioural constructs for 'susceptibility', 'severity', 'benefits' and 'barriers' but not 'cues to action' or 'self-efficacy'. The highest mean behavioural intention score was for 'benefits', whilst the lowest mean score was for 'barriers'. There were no significant differences in intention scores of parents receiving messages from a dietitian, university, health promotion team or school (P = 0·37). Intention scores did not differ in which messages were personalised based on child's name (P = 0·84) or grade level (P = 0·54). Conclusions: The findings suggest that messages that focus on the benefits of packing healthy lunchboxes may be particularly useful in improving intentions of parents to pack healthy foods for their children to consume at school.

Empirical studies to disentangle the effects of multicomponent implementation interventions are needed to inform the development of future interventions. This study aims to examine which behavior change techniques (BCTs) primarily targeting canteen manager are associated with school's healthy canteen policy implementation. This is a secondary data analysis from three randomized controlled trials assessing the impact of a "high,""medium,"and "low"intensity intervention primarily targeting canteen managers on school's implementation of a healthy canteen policy. The policy required primary schools to remove all "red"(less healthy items) or "banned"(sugar sweetened beverages) items from regular sale and ensure that "green"(healthier items) dominated the menu (>50%). The delivery of BCTs were retrospectively coded. We undertook an elastic net regularized logistic regression with all BCTs in a single model. Five k-fold cross-validation elastic net models were conducted. The percentage of times each strategy remained across 1,000 replications was calculated. For no "red"or "banned"items (n = 162), the strongest BCTs were: problem solving, goal setting (behavior), and review behavior goals. These BCTs were identified in 100% of replications as a strong predictor in the cross-validation elastic net models. For the outcome relating to >50% "green"items, the BCTs problem solving, instruction on how to perform behavior and demonstration of behavior were the strongest predictors. Two strategies were identified in 100% of replications as a strong (i.e., problem solving) or weak predictor (i.e., feedback on behavior). This study identified unique BCTs associated with the implementation of a healthy canteen policy.

Objective: This study assessed the effectiveness of a school-based intervention in reducing adolescents' sugar-sweetened beverage (SSB) consumption and percentage of energy from SSBs. Secondary outcomes were SSB consumption within school, average daily energy intake, and body mass index z-scores. Methods: Six secondary schools located in New South Wales, Australia were recruited to participate in a six-month pilot randomised controlled trial (1:1). The intervention included components targeting the school nutrition environment, curricula and community. Outcomes were collected via online surveys, observations, anthropometric measurements and project records. Between-group differences were assessed via linear mixed models. Results: At the six-month intervention endpoint (n=862) there were no statistically significant differences between students in intervention or control schools for mean daily intake of SSBs (8.55mL; CI -26.77, 43.87; p=0.63), percentage daily energy from SSBs (0.12% kJ; CI -0.55, 0.80; p=0.72), or for secondary outcomes. Acceptability of the school-based strategies were high, however intervention fidelity varied across schools. Conclusion: While acceptable, improving fidelity of implementation and increasing the duration or intensity of the intervention may be required to reduce SSB intake. Implications for public health: Engaging parents and education stakeholders in the development phase to co-design interventions may prove beneficial in improving intervention fidelity and enhance behavioural outcomes.

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.

Active Kids is a government-led, universal voucher program that aims to reduce the cost of participation in structured physical activity for all school-enrolled children in New South Wales (NSW), Australia. As part of the Active Kids program evaluation, this cross-sectional study examined the Active Kids' program's reach to children in NSW and their physical activity behaviors, before voucher use. Demographic registration data from all children (4.5¿18 years old) who registered for an Active Kids voucher in 2018 (n = 671,375) were compared with Census data. Binary and multinomial regression models assessed which correlates were associated with meeting physical activity guidelines and participation in the sessions of structured physical activity. The Active Kids program attracted more than half (53%) of all eligible children in NSW. Children who spoke a primary language other than English at home, were aged 15¿18 years old, lived in the most disadvantaged areas, and girls, were less likely to register. Of the registered children, 70% had attended structured physical activity sessions at least once a week during the previous 12 months, whilst 19% achieved physical activity guidelines. Active Kids achieved substantial population reach and has the potential to improve children's physical activity behaviors.

Aim: To assess the impact of a multistrategy intervention designed to improve teachers' implementation of a school physical activity (PA) policy on student PA levels. Methods: A cluster-randomized controlled trial was conducted in 12 elementary schools. Policy implementation required schools to deliver 150 minutes of organized PA for students each week via physical education, sport, or class-based activities such as energizers. Schools received implementation support designed using the theoretical domains framework to help them implement the current policy. Results: A total of 1,502 children in kindergarten to grade 6 participated. At follow-up compared with control, students attending intervention schools had, measured via accelerometer, significantly greater increases in school day counts per minute (97.5; 95% confidence interval [CI], 64.5 to 130.4; P <.001) and moderate to vigorous physical activity (MVPA) (3.0; 95% CI, 2.2-3.8, P <.001) and a greater decrease in sedentary time (-2.1; 95% CI, -3.9 to -0.4, P =.02) per school day. Teachers in intervention schools delivered significantly more minutes (36.6 min) of PA to their students at follow-up (95% CI, 2.7-70.5, P =.04). Conclusions: Supporting teachers to implement a PA policy improves student PA. Additional strategies may be needed to support teachers to implement activities that result in larger gains in student MVPA.

There is a need for effective interventions that improve the health and wellbeing of school and childcare staff. This review examined the efficacy of workplace interventions to improve the dietary, physical activity and/or sleep behaviours of school and childcare staff. A secondary aim of the review was to assess changes in staff physical/mental health, productivity, and students' health behaviours. Nine databases were searched for controlled trials including randomised and non-randomised controlled trials and quasi-experimental trials published in English up to October 2019. PRISMA guidelines informed screening and study selection procedures. Data were not suitable for quantitative pooling. Of 12,396 records screened, seven articles (based on six studies) were included. Most studies used multi-component interventions including educational resources, work-based wellness committees and planned group practice (e.g., walking groups). Multiple outcomes were assessed, findings were mixed and on average, there was moderate risk of bias. Between-group differences in dietary and physical activity behaviours (i.e., fruit/vegetable intake, leisure-time physical activity) favoured intervention groups, but were statistically non-significant for most outcomes. Some of the studies also showed differences favouring controls (i.e., nutrient intake, fatty food consumption). Additional robust studies testing the efficacy of workplace interventions to improve the health of educational staff are needed.

Issue addressed: Online systems offer opportunities to provide effective, ongoing support to childcare services to implement dietary guidelines. The study aimed to assess the effectiveness of a dissemination strategy on childcare service: (i) adoption; and (ii) use of an online menu planning program designed to increase compliance with dietary guidelines. Methods: A nonrandomised controlled trial was conducted with long day care services across Australia. All services received an email invitation to access an online evidence-based menu planning program. Services in the intervention also received training, telephone contact and provision of a portable computer tablet to encourage program adoption and use. Outcomes were assessed at the 6-month follow-up using analytics data recorded by the online program. Outcomes included the proportion of services having accessed the program (adoption) and the proportion of services with a current menu entered in the program (use as intended). Results: Twenty-seven interventions and 19 control services took part. At the 6-month follow-up, 100% vs 58% of services had adopted the online menu planning program (OR: 14.67, 95% CI: 2.43-infinity; P¿<¿0.01) and 41% vs 5% of services had a current menu entered in the program (OR: 9.99, 95% CI: 1.01-534.57; P¿<¿0.01) in the intervention and control arms respectively. Conclusions: This study highlights the need for strategies to support adoption and use of an online menu planning program in childcare services if the potential benefits of such a program are to be achieved. Future research should explore the effectiveness of differing strategies to increase adoption and use of online programs at scale. So what?: Strategies to support childcare service uptake and use of online programs are required in order for the potential public health benefits of such technologies to be realised.

Issue addressed: This study aimed to assess the feasibility and acceptability of using an existing school-based mobile communication application to deliver messages to parents on how to pack a healthy lunchbox. Methods: A telephone survey was conducted with 196 primary school principals within the Hunter New England region of New South Wales, Australia, in 2016. Results: Almost two thirds of primary schools (59%) currently use a school-based mobile communication application to communicate with parents. Most principals (91%) agreed school lunchboxes need improving, of which 80% agree it is a school's role to provide information and guidelines to parents. However, only 50% of principals reported currently providing such information. The provision of lunchbox messages to parents by a third party appeared an acceptable model of delivery by principals. Larger schools and schools in urban and lower socio-economic localities were more likely to have used a school-based mobile communication application. Conclusion: The majority of principals recognise student lunchboxes need improving. The use of school-based mobile communication applications appears to be feasible and acceptable by principals as a method of communicating lunchbox messages to parents. So what?: Use of school-based mobile communication applications may be an effective method for delivering health information at a population level. Future research should assess the potential efficacy of disseminating health interventions via this modality.

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: Improving implementation of school healthy canteen policies requires a comprehensive understanding of implementation barriers. Therefore, the aim of this study was to assess a range of barriers, as reported by canteen managers, using a quantitative survey instrument developed based on a theoretical framework. Methods: A cross sectional survey of primary school canteen managers from the Hunter New England region of New South Wales was conducted of eligible schools in the study region identified as having an operational canteen. Survey items assessed canteen manager employment status, canteen characteristics and potential barriers to healthy canteen policy implementation, aligned to the 14 domains of the theoretical domains framework via a 5-point Likert scale ranging from 1 (strongly disagree) to 5 (strongly agree). The mean domain scores of canteen managers were calculated, less than four indicating the canteen manager considered the domain was a barrier. Canteen managers were also asked to provide the current canteen menu for audit by a dietitian. Results: Of the 184 participants, 20% (n¿=¿36) were assessed as having menus compliant with the state policy. The five most common domains identified as potential barriers to policy implementation were behavioural regulation (n¿=¿117, 65%), skills (n¿=¿105, 57%), beliefs about capabilities (n¿=¿100, 55%), reinforcement (n¿=¿95, 52%) and goals (n¿=¿95, 52%). Canteen managers who reported optimism as a barrier had significantly lower odds of having a menu compliant with the state policy (OR¿=¿0.39; 95% CI 0.16-0.95, P¿=¿0.038). Conclusions: This study provides further evidence of perceived and actual barriers that canteen managers face when attempting to implement a healthy canteen policy, and highlights the need to address differences in canteen characteristics when planning implementation support. So what?: For public health benefits of nutrition policies within schools to be realised, the barriers to implementation need to be identified and used to help guide implementation support strategies.

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.

Issue addressed: Healthy canteen policies regulating the sales of food and beverages are available across all the states and territories in Australia. The aim of this study was to assess the compliance with a newly updated healthy school canteen policy in New South Wales (NSW) among a sample of secondary schools. Methods: A cross-sectional study of secondary school canteen menus was undertaken in selected regions across NSW (September 2017-November 2017). Government and Catholic secondary schools with a canteen menu publicly available on school websites were eligible for inclusion. Menus were classified according to the NSW Healthy School Canteen Strategy using a Quick Menu Audit tool, previously validated in primary schools. Results: Of 62 Catholic and 128 Government secondary schools located in the study region, 53 secondary schools (25 Catholic and 28 Government) were eligible to participate. The average percentage of "everyday" (healthy) items on secondary school menus was 54% (strategy criteria is >75%). Twenty-eight per cent of menus had no "sugary drinks" (should not be sold). None of the 53 menus assessed met all strategy criteria regarding the availability of foods and beverages. There was no statistically significant difference in meeting; (a) 75% minimum "everyday" items and (b) no "sugary drinks," by socio-economic region, remoteness, school enrolments or school type. Conclusions: If public health benefits of healthy eating policies are to be realised, secondary schools need to be supported to implement such policies. So what?: Future research assessing the impact of intervention strategies to support policy implementation in secondary schools is recommended.

Implementation of interventions in community organisations such as schools, childcare centres, and sporting clubs are recommended to target a range of modifiable risks of non-communicable diseases. Poor implementation, however, is common and has contributed to the failure of non-communicable disease interventions globally. This study aimed to characterise experimental research regarding strategies to improve implementation of chronic disease prevention programs in community settings. The review used data collected in three comprehensive systematic reviews undertaken between August 2015 and July 2017. Randomised controlled trials, including cluster design, and non-randomised trials with a parallel control group were included. The data were extracted to describe trial characteristics, implementation strategies employed, implementation outcomes and study quality. Of the 40 implementation trials included in the study, unhealthy diet was the most common risk factor targeted (n = 20). The most commonly reported implementation strategies were educational meetings (n = 38, 95%), educational materials (n = 36, 90%) and educational outreach visits (n = 29, 73%). Few trials were conducted 'at-scale' (n = 8, 20%) or reported adverse effects (n = 5, 13%). The reporting of implementation related outcomes; intervention adoption (n = 13, 33%); appropriateness (n = 11, 28%); acceptability (n = 8, 20%); feasibility (n = 8, 20%); cost (n = 3, 8%); and sustainability (n = 2, 5%); was limited. For the majority of trials, risk of bias was high for blinding of study personnel/participants and outcome assessors. Testing of strategies to improve implementation of non-communicable disease prevention strategies in community settings, delivered 'at-scale', utilising implementation frameworks, including a comprehensive range of implementation outcomes should be priority areas for future research in implementation science.

Objectives: Although evidence-based interventions (EBIs) and effective strategies to implement them exist, they cannot be used by policy makers and practitioners if they do not align with end users' needs. As such, adaptations to EBIs and implementation approaches are likely to occur to increase 'fit' with end users' capacity. This article describes an approach undertaken by a population health service delivery unit in one Australian state to develop an adapted implementation strategy to support the implementation of the mandatory healthy canteen policy (EBI) to all schools located in the service delivery region. Study design: This is a case study of adapting an intervention to improve implementation of the healthy canteen policy. Methods and results: This is a six-step pragmatic, empirically driven approach. The steps include (i) adapt, where appropriate, the EBI to facilitate implementation; (ii) identify end users' capacity for implementation; (iii) identify opportunities to adapt the implementation interventions while preserving meaningful intervention impact; (iv) undertake program adaptation; (v) develop training and resources to support delivery of implementation strategies and; (vi) evaluate the adapted intervention. This article describes the application of these steps by the authors to develop an adapted support strategy consistent with end users' needs. Conclusions: This study provides some guidance on how to adapt implementation support approaches particularly when EBIs cannot be adapted. Future empirical research providing guidance on making practical adaptation decisions are needed.

(1) Background: Our aim was to conduct objective, baseline food environment audits of two major western Sydney public hospitals and compare them to recently revised state nutritional guidelines. (2) Methods: A cross-sectional assessment was conducted (June¿July2017) across 14 fixed food outlets and 70 vending machines in two hospitals using an audit tool designed to assess the guideline's key food environment parameters of availability, placement, and promotion of 'Everyday' (healthy) and 'Occasional' (less healthy) products. (3) Results: Availability: Overall, Everyday products made up 51% and 44% of all products available at the two hospitals. Only 1/14(7%) fixed outlets and 16/70(23%) vending machines met the guideline's availability benchmarks of =75% Everyday food and beverages. Proportion of Everyday products differed among different types of food outlets (café, cafeteria, convenience stores). Placement: On average, food outlets did not meet recommendations of limiting Occasional products in prominent positions, with checkout areas and countertops displaying over 60% Occasional items. Promotion: Over two-thirds of meal deals at both hospitals included Occasional products. (4) Conclusion: Baseline audit results show that substantial improvements in availability, placement, and promotion can be made at these public hospitals to meet the nutrition guidelines. Audits of other NSW hospitals using the developed tool are needed to investigate similarities and differences in food environment between sites. These findings highlight the need for ongoing tracking to inform whether the revised guidelines are leading to improved food environments in health facilities.

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: Implementation interventions delivered in schools to improve food provision have been found to improve student diet and reduce child obesity risk. If the health benefits of food availability policies are to be realised, interventions that are effective need to be implemented at scale, across an entire population of schools. This study aims to assess the potential effectiveness of an intervention in increasing the implementation, at scale, of a healthy canteen policy by Australian primary schools. Methods: A non-controlled before and after study was conducted in primary schools located in the Hunter New England region of New South Wales, Australia. Schools received a multi-component intervention adapted from a previous efficacious and cost-effective randomised control trial. The primary trial outcome was the proportion of canteen menus compliant with the state healthy canteen policy, assessed via menu audit at baseline and follow-up by dietitians. Secondary outcomes included policy reach and adoption and maintenance policy implementation. Results: Of the 173 schools eligible for inclusion in the trial, 168 provided menus at baseline and 157 menus were collected at follow-up. At follow-up, multiple imputation analysis found 35% (55/157) of schools compared to 17% (29/168) at baseline (OR = 2.8 (1.6-4.7), p = < 0.001) had menus compliant with the state healthy canteen policy. As an assessment of the impact of the intervention on policy reach, canteen manager and principal knowledge of the policy increased from 64% (n = 76) and 38% (n = 44) respectively at baseline to 69% (n = 89) and 60% (n = 70) at follow-up (p = 0.393, p = 0.026). Adoption of the policy increased from 80% (n = 93) at baseline to 90% (n = 104) at follow-up (p = 0.005) for principals, and from 86% (n = 105) to 96% (n = 124) (p = 0.0001) for canteen managers. Multiple imputation analysis showed intervention effects were maintained six-months post intervention (33% of menus compliant OR = 2.6 (1.5-4.5), p = < 0.001 compared to baseline). Conclusions: This study found school canteen compliance with a healthy food policy increased in association with a multi-strategy intervention delivered at scale. The study provides evidence for public health policy makers and practitioners regarding strategies and modes of support required to support improvement in nutrition policy implementation across entire populations of schools.

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.

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.

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.
