A randomised controlled trial of an intervention to increase the implementation of a healthy canteen policy in Australian primary schools: study protocol.

BackgroundThe implementation of healthy school canteen policies has been recommended as a strategy to help prevent unhealthy eating and excessive weight gain. Internationally, research suggests that schools often fail to implement practices consistent with healthy school canteen policies. Without a population wide implementation, the potential benefits of these policies will not be realised. The aim of this trial is to assess the effectiveness of an implementation intervention in increasing school canteen practices consistent with a healthy canteen policy of the New South Wales (NSW), Australia, government known as the `Fresh Tastes @ School NSW Healthy School Canteen Strategy’.Methods/designThe parallel randomised trial will be conducted in 70 primary schools located in the Hunter region of New South Wales, Australia. Schools will be eligible to participate if they are not currently meeting key components of the healthy canteen policy. Schools will be randomly allocated after baseline data collection in a 1:1 ratio to either an intervention or control group using a computerised random number function in Microsoft Excel. Thirty-five schools will be selected to receive a multi-component intervention including implementation support from research staff, staff training, resources, recognition and incentives, consensus and leadership strategies, follow-up support and implementation feedback. The 35 schools allocated to the control group will not receive any intervention support as part of the research trial. The primary outcome measures will be i) the proportion of schools with a canteen menu that does not contain foods or beverages restricted from regular sale (`red’ and `banned’ items) and ii) the proportion of schools where healthy canteen items (`green’ items) represent the majority (>50%) of products listed on the menu. Outcome data will be collected via a comprehensive menu audit, conducted by dietitians blind to group allocation. Intervention effectiveness will be assessed using logistic regression models adjusting for baseline values.DiscussionThe proposed trial will represent a novel contribution to the literature, being the first randomised trial internationally to examine the effectiveness of an intervention to facilitate implementation of a healthy canteen policy.Trial registrationAustralian New Zealand Clinical Trials Registry ACTRN12613000311752

CAFÉ: a multicomponent audit and feedback intervention to improve implementation of healthy food policy in primary school canteens: protocol of a randomised controlled trial

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 is that 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. Trial registration number ACTRN12613000543785.

CAFÉ: a multicomponent audit and feedback intervention to improve implementation of healthy food policy in primary school canteens: a randomised controlled trial

BackgroundThe implementation of nutrition policies in schools has been recommended as a strategy to improve child dietary intake. Internationally, research suggests that the majority of schools do not implement these policies. In New South Wales (NSW), Australia, the NSW Healthy School Canteen Policy requires that school canteens prohibit the sale of ‘red’ foods (i.e. foods that are typically nutrient poor and high in energy, such as confectionary and deep-fried foods) and ‘banned’drinks (i.e. soft drinks); and that the majority of items on the menu are ‘green’ (i.e. foods that are good sources of nutrients, such fruits, vegetables and lean meats). This study examined the impact of a multicomponent audit and feedback intervention on schools’ implementation of the NSW Healthy School Canteen Policy. A secondary aim was to assess the impact of the intervention on menu composition.MethodsThis study was a parallel group randomised controlled trial with 72 rural and remote primary schools (36 interventions, 36 controls) located in one region within NSW, Australia. Intervention schools received an initial face to face contact and up to four cycles of audit and feedback (consisting of a menu audit, written feedback report and telephone feedback) over a 12-month period. The primary trial outcomes were the proportion of schools with a canteen menu that had: i) no ‘red’ foods or ‘banned’ drinks; and ii) >50% ‘green’ items, as assessed via standardised menu audits undertaken by trained dietitians. For each primary outcome, between-group differences were assessed using Fisher’s exact test under an intention to treat approach.ResultsThere was insufficient evidence to conclude the intervention had a positive impact on the proportion of intervention schools with no ‘red’ or ‘banned’ items on their menu (RR = 2.8; 95% CI: 0.9 to 8.9; p = 0.0895), or on the proportion of intervention schools with more than 50% ‘green’ items (RR = 1.5; 95% CI: 0.7 to 3.2; p = 0.2568). These findings remained non-significant in the multiple imputation analyses. Intervention schools were significantly more likely to have a lower percentage of ‘red’ items (p-value: 0.007) and a higher percentage of ‘green’ items on the menu (p-value: 0.014). This remained statistically significant in the multiple imputation analyses for ‘red items’ (p-value: 0.0081) but not for ‘green’ items (p-value: 0.0910).ConclusionsWhile there was insufficient statistical evidence to suggest that this multicomponent audit and feedback intervention was effective in improving primary schools’ compliance with a healthy canteen policy, the intervention demonstrated some positive impact in reducing the availability of ‘red’ items on the menu.Trial registrationThis trial was prospectively registered with the Australian New Zealand Clinical Trials Registry (ACTRN12613000543785).

Validity of four measures in assessing school canteen menu compliance with state-based healthy canteen policy

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.

Online canteens: awareness, use, barriers to use, and the acceptability of potential online strategies to improve public health nutrition in primary schools

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.

Economic analysis of three interventions of different intensity in improving school implementation of a government healthy canteen policy in Australia: costs, incremental and relative cost effectiveness

BackgroundNo evaluations of the cost or cost effectiveness of interventions to increase school implementation of food availability policies have been reported. Government and non-government agency decisions regarding the extent of investment required to enhance school implementation of such policies are unsupported by such evidence. This study sought to i) Determine cost and cost-effectiveness of three interventions in improving school implementation of an Australian government healthy canteen policy and; ii) Determine the relative cost-effectiveness of the interventions in improving school implementation of such a policy.MethodsAn analysis of the cost and cost-effectiveness of three implementation interventions of varying support intensity, relative to usual implementation support conducted during 2013–2015 was undertaken. Secondly, an indirect comparison of the trials was undertaken to determine the most cost-effective of the three strategies. The economic analysis was based on the cost of delivering the interventions by health service delivery staff to increase the proportion of schools ‘adherent’ with the policy.ResultsThe total costs per school were
