Convergent findings from several studies document that children, especially those who are already overweight or obese or from racial / ethnic minority groups, are at risk for accelerated weight gain during the summer months. Therefore, this project is comprised of three separate community-based interventions designed to increase access to healthy meals and physical activity opportunities to minimize excess summer weight gain in elementary school children from a diverse, low-income Rhode Island community. Specifically, we will complete a quasi-experimental study in which we will design and deliver a physical activity intervention in conjunction with the Summer Food Service Program (SFSP) to 50 children living in a low-income, urban community. We anticipate that the addition of physical activity programming to the SFSP, a federal program funded by the USDA which reimburses states for serving lunch meals to children during the summer in communities where at least 50% of students are eligible for free or reduced-price school meals, will increase both the acceptability and effectiveness of the SFSP and affect 1) physical activity levels, 2) sedentary behavior, and 3) diet quality. The primary outcome (change in BMI z-score) will be compared between the 50 kids enrolled in the active intervention and 50 children enrolled in the control condition, both recruited from the same community.
