Abstract	A meta-analysis was conducted on school-based interventions to reduce obesity in children. Sixty-six (k = 66, N = 31,059) comparisons from 40 published studies from 1997 through 2008 were included in analyses. Results indicated a significant effect for school-based interventions with an overall weighted effect size of r = 0.05. Several moderating factors were examined to explain the heterogeneity in study outcomes. Interventions that were universal (k = 37, r = 0.07), conducted in elementary schools (k = 41, r = 0.06), implemented collaboratively (k = 19, r = 0.12), primarily included children of Asian ethnicity (k = 5, r = 0.30), encouraged nutritional change (k = 28, r = 0.13), and sought to reduce sedentary behaviors (k = 17, r = 0.15) were identified as more successful in reducing students' obesity-related outcomes. Factors that resulted in negative effects for school-based programs included interventions of short duration (k = 11, r = -.04) and those that implemented system-wide changes in nutrition (k = 15, r = -0.03). The variability in study effect sizes is discussed, and recommendations are made for future school-based interventions targeting children. (Contains 1 figure and 3 tables.) (As Provided).
