Methods: Using a community-based participatory approach, BGC staff and academic researchers developed intervention components informed by formative studies and based on a social ecological theory framework. Components included healthy eating and physical activity policy implementation, staff training, a challenge/self-monitoring program for healthy behaviors, a peer-coaching program for healthy behaviors, and a social marketing campaign. Preliminary intervention efficacy was assessed through a single group, pre-post study design with measured collected at baseline and 6 months.
