Prevalence of current school-level nutrition policies and practices of secondary schools in NSW, Australia

National Policies to Limit Nutrients, Ingredients, or Categories of Concern in School Meals: A Global Scoping Review

The school food environment is a key intervention point for influencing children's and adolescents' diets. As more countries establish school meal programs to provide critical nourishment to students, establishing standards for the foods served can increase the consumption of key nutrients and limit the consumption of foods that do not build health. This global scoping review explores the prevalence and basic characteristics of national policies that regulate food served through school meals across 193 countries, particularly by restricting the provision of categories, nutrients, or ingredients of nutritional concern. We gathered evidence from policy databases, grey literature, peer-reviewed literature, and primary policy documents. We included nationally mandated policies that included restrictions on categories, nutrients, or ingredients of concern served in school meals. Policies that were sub-national, voluntary, and/or did not include restrictive language were excluded from this review. Data was collected in research electronic data capture then extracted into Microsoft Excel and analyzed for policy frequency, prevalence by world region or country income group, and prevalence of certain policy characteristics. Globally, only 15% of countries were found to have a national-level policy restricting foods served through school meals in some capacity, including either nutritional or categorical restrictions. The majority of these policies were found in high-income countries, and no low-income countries had a policy meeting inclusion criteria. Policies in Latin-American and Caribbean countries limited the content of more nutrients of concern than in other regions. Although many policies included explicit guidelines to monitor implementation, few outlined mechanisms for policy enforcement. Future research should evaluate the impact of various school meal regulatory approaches, including implementation of similar policies at sub-national levels, and other elements that affect the impact of school meal programs, such as procurement, infrastructure, costs to school and to students and their families, and acceptability and consumption of foods provided.

Comparative analysis of school food policies in Australian jurisdictions: Insights for more effective policy action

ISSUE ADDRESSED

School food policies in Australia have the potential to positively impact healthy eating in schools. While the policies are reviewed regularly, it is unknown if revised school food policies have incorporated the recommendations from a 2020 review of nutrition policies in publicly funded institutions. This review aims to examine the current state of Australian school food policy environment, including national-level guidelines, food safety, allergy, and anaphylaxis management policies.

METHODS

School food policy documents were identified by searching the federal government, and Departments of Health and Education websites of Australian jurisdictions. The L'Abbé framework for monitoring and evaluation of nutrition policies guided the data analysis.

RESULTS

Eleven policies/guidelines from Australian national and state/territory governments were reviewed in 2023. Four state/territory policies had major updates since 2020. The consistency of nutrition standards improved across five jurisdictions, although a common nutrient classification system would have allowed better comparison. Implementation guides/tools and supporting resources were provided in all policies although their comprehensiveness varied. Policy monitoring and evaluation guide/tools, and local food procurement were incorporated in two additional policies. School principals were responsible for policy implementation and schools for independent compliance monitoring.

CONCLUSION

Continued improvement in monitoring and evaluation plans, policy review timelines, and support systems for schools is needed to enhance implementation and impact of school food policies. External stakeholder support may help school leadership in more effective policy implementation. SO WHAT?: Limited progress in incorporating recommendations into current school food policies calls for additional support and strategies to enhance policy implementation and monitoring.

National Policies to Limit Food Marketing and Competitive Food Sales in Schools: A Global Scoping Review

School food environments contribute to children's nutritional intake and overall health. As such, the World Health Organization and other public health organizations encourage policies that restrict children's access and exposure to foods and beverages that do not build health in and around schools. This global scoping review explores the presence and characteristics of policies that restrict competitive food sales and marketing for unhealthy foods across 193 countries using evidence from policy databases, gray literature, peer-reviewed literature, and primary policy documents. Policies were included if they were nationally mandated and regulated marketing and/or competitive foods in the school environments. Worldwide, only 28% of countries were found to have any national-level policy restricting food marketing or competitive food sales in schools: 16% of countries restrict marketing, 25% restrict competitive foods, and 12% restrict both. Over half of policies were found in high-income countries. No low-income countries had either policy type. Eight marketing policies (27%) and 14 competitive foods policies (29%) lacked explicit guidelines for either policy monitoring or enforcement. Future research is needed to assess the prevalence of policies aimed at improving other key aspects of the school food environment, such as dietary quality of school meals or food procurement, as well as assess the implementation and efficacy of existing policies.

Robust implementation of school food policy is needed to improve nutritional outcomes of children in European and Western Pacific countries: A systematic review

OBJECTIVE

The present systematic review explored compliance status with school food policies in Europe and the Western Pacific regions, challenges and facilitators of policy compliance, and its impact on children's diets and nutrient intakes.

RESEARCH METHODS

An electronic search for full-text research articles published between January 2009 and July 2023 was conducted in Science Direct and PubMed scientific databases.

RESULTS

A total of 659 titles and abstracts were screened, and final data was extracted from 34 included studies. Results showed low compliance with the school food policy in Europe and the Western Pacific regions. The European schools chad better compliance than the Western Pacific, and supportive interventions improved policy adherence. Impact assessment studies reported that the implementation of the school food policy increased fruit and vegetable consumption, thus increasing nutrient intakes (vitamin A, vitamin D, iron, calcium, folate, and dietary fibers). However, its impact on the availability and consumption of foods high in fat, sugar, and salt (HFSS) was less conclusive. The effects of the policy on the school food environment indicated no significant improvement.

CONCLUSION

Results highlighted the need for additional support and surveillance at the school level to ensure adequate policy compliance.

Scanning for Obesogenicity of Primary School Environments in Tshwane, Gauteng, South Africa

The purpose of this study was to scan for the obesogenicity of primary school environments in Tshwane, Gauteng, South Africa. This study was carried out in ten public primary schools in the Tshwane West district of the Gauteng province. An observational design was used to collect the data. Data collection was conducted using an observational checklist guided by the Analysis Grid for Environments Linked to Obesity (ANGELO) framework. The findings revealed that although a nutrition policy was available in most schools, few schools were communicating the policy. Despite all the schools having sports fields, children were not exercising. Most schools also had a school nutrition programme. Most primary schoolchildren's lunchboxes contained sweets, sugar-sweetened beverages, and snacks. A few lunchboxes contained fruits and vegetables. Primary schools in Tshwane West did not comply with most aspects of the school mapping environment, indicating that the school environments were obesogenic. It is therefore essential to scan for obesogenicity in all South African schools so that tailor-made interventions can be implemented to rectify and further prevent obesogenic school environments.

A trial of a six-month sugar-sweetened beverage intervention in secondary schools from a socio-economically disadvantaged region in Australia

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.

The barriers and enablers to implementing the NSW Healthy School Canteen Strategy in secondary schools in the Illawarra and Shoalhaven region - A qualitative study

ISSUE ADDRESSED

In 2017, the New South Wales Healthy School Canteen Strategy (Strategy) was introduced into primary and secondary schools. Studies have reported that secondary schools have a lower level of compliance with healthy canteen policies compared with primary schools. This study aims to identify and describe the barriers and enablers to implementing the Strategy in Department of Education (DoE) secondary schools in the Illawarra and Shoalhaven regions.

METHODS

The framework underpinning the study was the systems theory. Canteen managers (CM) and principals from the 21 DoE secondary schools in the Illawarra and Shoalhaven regions were invited to participate in semi-structured interviews. The interviews were structured around the five focus areas of the Strategy, including questions on school nutrition policies and the role of the canteen. Data were collated using the interview guides as a framework and qualitative content analysis, using manual coding, was undertaken.

RESULTS

Eight (38%) schools participated with seven CMs and six principals interviewed. Barriers to implementing the Strategy included the changing role of the canteen, the increased demands placed on CMs and inconsistencies between the school food environment and the Strategy. Enablers included monitoring implementation, and internal and external support. This study also recognised that previously identified barriers to healthy canteen strategy implementation are ongoing.

CONCLUSIONS

The school canteen is an integral part of the school environment and therefore needs whole-of-school support if successful implementation of the Strategy is to occur.

SO WHAT

Addressing the barriers and promoting the enablers identified in this study will support better nutrition policy implementation in secondary schools.
