The overall goals of this integrated project are: 1) to provide a comprehensive empirical examination of the influences of economic, lifestyle, and social factors on obesity by combining detailed individual-level survey data with regional economic and environmental information on food and fast food prices, local area food store, eating places and physical activity-related outlet density measures, and area crime data and, 2) to provide an extensive outreach program that will use the findings from our research to inform both policy makers and households of which policies, programs, and practices are effective at combating obesity.
