LOE: I The purpose of this study was to systematically review the effectiveness of childhood obesity programs in the United States and other high-income countries. Design: Systematic review Sampling method: Searched Medline, Embase, PsychInfo, CINAHL, clinicaltrials.gov, and the Cochrane Library for relevant English-language studies. Studies were only eligible is the intervention was primarily implemented in the community setting, had at least 1 year of follow-up after baseline, and compared results from an intervention to a comparison group. Sampling size: 9 community-based studies were included. 5 4 of the 9 studies which used combined diet and physical activity approaches reported significant reduction in adiposity and outcomes. 1 of the studies reported improvements in physical activity. The evidence suggests that combined interventions implemented in multiple settings like the home, community and school would be the most effective at preventing weight problems. A significant decrease in adiposity was noted in programs that had longer follow-up periods and focused on middle school age and younger. Weaknesses: 1. Many of the studies published in this area are of suboptimal study design which can contribute to bias. 2. A lack of published data from unsuccessful programs may lead to a publication bias. 3.
