ABSTRACT

BACKGROUND: Many Americans have diets that do not meet the dietary guidelines set by the US Department of Agriculture (USDA). Additionally, low-income people have the highest rates of obesity and have difficulty accessing the necessary foods for maintaining a healthful diet. CONTEXT: In December 2007 and January 2008, 21 retail food stores in Central Falls, Rhode Island, where residents were predominantly low-income Hispanics, were evaluated for the availability and costs of foods that fulfill the USDA's Thrifty Food Plan (TFP) guidelines. METHODS: Each surveyed store was evaluated for variety and weekly cost of 3 different types of market baskets (2 families and an elder). Each store's proximity to public transportation was estimated by using geographic information systems mapping. OUTCOME: Only 2 stores in Central Falls and the discount supermarket in an adjacent city, Pawtucket, carried enough variety of foods to fill the TFP basket. At the 2 stores, costs were up to 40% higher, and at the discount store, costs were up to 18% cheaper, than the national average. Each of the stores was accessible by public transportation. INTERPRETATION: Meeting the USDA TFP guidelines is difficult in this low-income, predominantly Hispanic city. Although the components of the TFP are available, high prices may make a nutritious diet unaffordable.
