Intermediate and secondary school food environment in New Zealand: Food and drink menu assessment.

Issue addressed: Nutrition-related obesity is rising among adolescents in New Zealand with an estimated one in eight children being obese. The school environment is an ideal community setting for encouraging a healthy lifestyle as schools contain a diverse population and involve students and parents. However, the healthiness of food available to intermediate and secondary school students (Years 7-13) is unknown. This study assessed how food and drink menus from schools align with policy guidelines for healthy school food environments.

Methods: A convenience sample of NZ schools' (years 7-13; ages 10-19) menus was collected in 2020. Menus were classified using traffic light criteria. A toolkit was developed by three nutritionists and one dietitian (with trained staff support) to aid with menu classification. Menu quality was evaluated against school characteristics and policy use.

Results: Of the school menus assessed (n = 60), 3.3% met the recommendation for the provision of 75% 'green' items. 'Red' items were the main contributors (mean = 53.6%). Schools with high socio-economic status (deciles 8-10; 14.3%; p < 0.05) and small school size (<749 students; 14.1%; p < 0.025) were associated with a higher proportion of 'green' items. Community (19.3%) and in-house (25.9%) food providers provided a lower percentage of 'amber' items than school providers (39.3%; p < 0.001). In-house providers (64.6%) had a greater percentage of 'red' items than school providers (48.2%; p = 0.017).

Conclusion: Food available in schools (Years 7-13) tends to be unhealthy. A national nutrition policy could improve the school food environment, especially in schools with large populations and low socio-economic status. SO WHAT?: School demographics have been associated with menu quality but further research within these schools is needed to identify the gaps to improve equitable outcomes within school food environments.
