School-based employee interventions can benefit the health of staff and have the potential to influence the health of school students through role-modelling. However, interventions within schools typically focus on students, with very few studies addressing obesity and related health behaviours among school staff. A systematic review of the peer-reviewed literature published between January 2000 and May 2020 was undertaken to synthesize the evidence on the impact that school-based obesity prevention programmes have on the staff they employ. Search terms were derived from four major topics: (i) school; (ii) staff; (iii) health promotion and (iv) obesity. Terms were adapted for six databases and three independent researchers screened results. Studies were included if they reported on the outcomes of body weight, dietary behaviours and/or physical activity. Of 3483 papers identified in the search, 13 studies met the inclusion criteria. All 13 studies included an intervention that focussed on improving nutrition, physical activity or both. All included studies demonstrated a positive outcome for either dietary intake, weight or body mass index or physical activity outcomes, however not all results were statistically significant. The included studies showed promising, although limited, impacts on employee health outcomes. This review demonstrated a lack of global focus and investment in interventions targeting school staff, particularly in contrast to the large amount of research on school-based health promotion initiatives focussed on students. There is a need for further research to understand effective interventions to promote health and prevent obesity in this large, diverse and influential workforce.

Objective: Government policy guidance in Victoria, Australia, encourages schools to provide affordable, healthy foods in canteens. This study analysed the healthiness and price of items available in canteens in Victorian primary schools; and associations with school characteristics. Design: Dietitians classified menu items (main, snack, beverage) using the red, amber, green traffic light system defined in the Victorian government’s school canteens and other school food services policy. This system also included a black category for confectionary and high sugar content soft drinks which should not be supplied. Descriptive statistics, and regressions were used to analyse differences in the healthiness and price of main meals, snacks and beverages offered, according to school remoteness, sector (government, Catholic/independent), size, and socio-economic position. Setting: State of Victoria, Australia Participants: A convenience sample of canteen menus drawn from three previous obesity prevention studies in 48 primary schools between 2016-2019. Results: On average, school canteen menus were 21% ‘green’ (most healthy – ‘everyday’), 53% ‘amber’ (‘select carefully’), 25% ‘red’ (‘occasional’) and 2% ‘black’ (banned) items, demonstrating low adherence with government guidelines. ‘Black’ items were more common in schools in regional population centres. ‘Red’ main meal items were cheaper than ‘green’ (mean difference -$0.48 (95%CI -0.85, -0.10)) and ‘amber’ -$0.91 (-1.27, -0.57)) main meal items. In ∼50% of schools, the mean price of 'red’ main meal, beverages and snack items were cheaper than ‘green’ items; or no ‘green’ alternative items were offered. Conclusion: In this sample of Victorian canteen menus, there was no evidence of associations of healthiness and pricing by school characteristics except for regional centres having the highest proportion of ‘black’ (banned) items compared to all other remoteness categories examined. There was low adherence with state canteen menu guidelines. Many schools offered a high proportion of ‘red’ food options, and ‘black’ (banned) options, particularly in regional centres. Unhealthier options were cheaper than healthy options. More needs to be done to bring Victorian primary school canteen menus in line with guidelines.
