- We examine effectiveness of a multicomponent school-based intervention.
- The intervention is based on the CDC's coordinated school health approach.
- Screen time and vegetable/fruit intake are related to physical activity changes.
- More favorable results are observed in vigorous than moderate physical activity.
- School's implementation fidelity is related to students' vigorous activity changes.
ObjectiveTo evaluate if the HEROES Initiative, a school-based childhood obesity prevention program based on the U. S. Centers for Disease Control and Prevention (CDC)'s coordinated school health approach was able to effectively increase physical activity among elementary and middle school students who were exposed to the program for 18 months and to determine student and school-level predictors of success.MethodStudents who participated in physiological data collection were invited to participate in a survey at baseline, 6 months, and 18 months (N = 1091, 8 schools). The dropout rate at 18 months was 39.1% when graduates were counted. Data was analyzed using generalized estimating equations.ResultsA significant increase (p = .0067) was observed in vigorous-intensity physical activity (VPA) but a non-significant increase (p = .1753) was observed in moderate-intensity physical activity (MPA). Each school's implementation fidelity score was also only associated with VPA increases. Students' screen time and vegetable/fruit intake were independently associated with both VPA and MPA increases. Body mass index of students was not predictive of VPA or MPA changes.ConclusionAn 18-month school-based intervention that employs the CDC's coordinated school health approach appears to be effective in increasing physical activity among elementary and middle school children.
