Community action to prevent childhood obesity: lessons from three US case studies.

BACKGROUND: A 2005 Institute of Medicine report argues that "prevention of obesity in children and youth is, ultimately, about community," yet the literature lacks empirical research on what communities are doing to prevent childhood obesity. This research helps fill this gap and highlights promising practices.

CASES: This research entailed exploratory analysis of three descriptive case studies of community efforts to prevent childhood obesity in the northeastern United States: Shape Up Somerville in Massachusetts, MA (urban), Whole Community Project in New York, NY (semiurban), and Eat Well Play Hard Chemung in NY (semirural). Data included stakeholder interviews (n=23), participant observation (n ≥ 7 events and meetings/case), and document analysis (n≈100/case) from project inceptions until March, 2010. Meeting participation was tracked. Data were coded for actions and strategies. Actions were mapped to an adapted version of the ANalysis Grid for Environments Linked to Obesity (ANGELO) framework.

DISCUSSION: These three projects were successful in changing physical environments for food and activity through program and event offerings. The projects were less active in generating policy and economic change. The scale and scope of actions related to project longevity. Demographics of key project stakeholders may have hinged on individual and institutional identities of project facilitators and on intentionality of inclusion strategies.

CONCLUSION: Such projects could likely generate greater scope and scale of environmental changes to prevent childhood obesity if funding agencies provided long-term financial support and technical assistance, even if at lower levels. Diversity of participation would also benefit from stable support and from dispersal of decision-making powers, including through distributed funding.
