title: Examining associations among obesity and per capita farmers' markets, grocery stores/supermarkets, and supercenters in US counties.
abstract: Fruit and vegetable consumption is an important component of a healthful diet, yet fruits and vegetables are underconsumed, especially among low-income groups with high prevalence rates of obesity. This study used data from the US Department of Agriculture Economic Research Service Food Environment Atlas to examine county-level associations among obesity prevalence and per capita farmers' markets, grocery stores/supermarkets, and supercenters, adjusted for natural amenities, percent black, percent Hispanic, median age, and median household income, stratified by county metropolitan status. In models that included all three of the food venues, supercenters and grocery stores per capita were inversely associated with obesity in the combined (metro and nonmetro) and metro counties. Farmers' markets were not significant in the model for combined (metro and nonmetro) or for metro counties alone, but were significantly inversely related to obesity rates in the model for nonmetro counties. In this ecologic study, density of food venues was inversely associated with county-level obesity prevalence. Thus, future research should examine similar associations at the individual-level.
