摘要：Background: The problem of overweight and obesity has reached epidemic proportions in the United States as well as globally. School-based interventions, after school interventions, home and family based interventions and community-based interventions have been developed to address the problem of childhood overweight and obesity. Understanding the best approach to impact obesity rates is a necessity for health professionals. Therefore, the purpose of this article was to examine the efficacy of community-based interventions targeting childhood obesity and to further develop a set of recommendations for future interventions. Methods: A systematic literature review was conducted independently by two authors in four relevant databases. Inclusion criteria were (1) primary research; (2) overweight or obesity prevention interventions; (3) community-based; (4) studies that used a quantitative design and provided outcome data; and (5) were published through September 2012. Results: A total of 15 interventions met the inclusion criteria, of which six were randomized controlled trials. Eleven interventions were from the United States with one each from Canada, Australia, England and Tonga. Eight interventions utilized a theoretical framework, with Social Cognitive Theory being the most commonly utilized theory. Discussion: Recommendations for future community based interventions include utilization of multiple settings including schools, use of behavioral theory and its explicit operationalization, use of interactive strategies including social support and involvement of parents and family, along with use of environmental change approaches.
