Changes in School Competitive Food Environments after a Health Promotion Campaign

Equity Focus

This study targets school-based interventions to improve the nutritional environment of school meals in classrooms.

Case Summary

This project describes changes in competitive nutrition environments in 100 K-8 schools participating in the Philadelphia Campaign for Healthier Schools. Interviews with school staff were used to elicit information about policies, practices, and guidelines to restrict/limit competitive foods in schools, before and 1 year into the campaign. To increase the validity of responses, respondents provided documentation for reported policies and guidelines. Baseline interviews were conducted between April and June 2011 and follow-up interviews were conducted between April and June 2012. At follow-up, significantly more schools reported having policies and/or guidelines in place to regulate food as a reward in the classroom, food served at parties and celebrations, outside foods allowed in school, and the availability of sodas and sugar-sweetened beverages. There were no measurable effects on food available in school stores, fundraisers, or afterschool programs.

Lessons Learned

  • In the context of a comprehensive school wellness policy, school wellness councils were associated with increases in school-level policies and practices that improved the competitive nutrition environment.
