About this trial
Nearly one in five children are obese, and disparities in overweight and obesity between children from low- and middle-to-high-income households persist despite a multitude of school-based interventions. The structured days hypothesis posits that structure within a school day plays a protective role for children against obesogenic behaviors, and, ultimately, prevents the occurrence of excessive weight gain, thus, past school-based efforts are misplaced. This study will provide access to healthy structured programming via vouchers to afterschool programs and summer day camps during two "windows of vulnerability" (ie afterschool and summer) for low-income children.

Treatments tested in this trial
After school program
BehavioralThe after school program are existing community-based programs that take place immediately after the regular school day (typically 3:00-6:00pm); are located in a school; are available daily throughout the academic year (Monday through Friday); and provide a combination of scheduled activities, which include a snack, homework assistance/tutoring, enrichment activities (e.g., arts and crafts, music), and opportunities for children to be physically active.
Summer day camp
BehavioralThe summer day camp programs are existing camps which take place at schools from which children will be recruited. The camps are not singularly focused, such as sport camps or academic only camps. Rather, the camps provide indoor and outdoor opportunities for children to be physically active each day, provide enrichment and academic programming, as well as provide breakfast, lunch, and snacks.
