Students\u27 consumption of high and low nutrition foods and reduced plate waste by schools\u27 wellness-related policies and garden program participation
Background: Participation in school-based programs that may support children\u27s nutritious dietary behaviours varies across schools. We examined school participation in wellness-related policies, school-based garden programs and students\u27 dietary behaviours. Methods: Among matching schools who did and did not participate in school-based garden programs, we analysed the lunches of 80 Pittsburgh Public Schools (PPS) students in 1st, 2nd, 6th and 7th grades during Autumn 2019 using digital food photography. We also acquired school wellness policy data. Using cross-sectional linear regression, we estimated the association between school-based garden programming, wellness-related policies and dietary outcomes, adjusting for grade. Results: School\u27s implementation of nutrition services policies was negatively associated with energy wasted from lunch ((Formula presented.)). The number of semesters the students\u27 school had participated in the garden program was positively associated with students\u27 whole grain consumption ((Formula presented.)). Conclusions: Cross-sectional associations suggest that schools that are more engaged in wellness policies and garden programs may provide environments that are more supportive of students\u27 nutrition than in other schools
