目标。最近的研究表明了店内内容的重要性，但大多数食物获取差异研究都集中在商店获取的差异上，而不是他们携带的食物。这项研究调查了主要食品的货架空间，以测试其他类型的商店是否可以抵消非裔美国人社区超市相对缺乏的影响。新奥尔良人口普查区的数据与卫生部门关于2004-2005年开办食品店的信息相结合。水果、蔬菜和高能量零食的货架空间是用测量轮评估的，并在商店样本中建立了协议。邻域食品的可得性是通过将区域中心2公里内所有商店的货架空间相加来计算的。回归分析评估了地区种族构成与总体食物供应之间的关系。非洲裔美国人社区的超市较少，新鲜水果和蔬菜的总供应量也低于其他社区。零食的可得性没有差异，结论。在非裔美国人社区，其他类型的商店在提供新鲜农产品方面并没有抵消超市相对缺乏的影响，尽管它们在提供休闲食品方面发挥了作用。改变这些商店提供的食物组合可能会缓解这些不平等。(C) 2010爱思唯尔公司版权所有。
Objective. Recent works demonstrates the importance of in-store contents, yet most food access disparity research has focused on differences in store access, rather than the foods they carry. This study examined instore shelf space of key foods to test whether other types of stores might offset the relative lack of supermarkets in African-American neighborhoods.Methods. New Orleans census tract data were combined with health department information on food stores open in 2004-2005. Shelf space of fruits, vegetables, and energy-dense snacks was assessed using a measuring wheel and established protocols in a sample of stores. Neighborhood availability of food was calculated by summing shelf space in all stores within 2 km of tract centers. Regression analyses assessed associations between tract racial composition and aggregate food availability.Results. African-American neighborhoods had fewer supermarkets and the aggregate availability of fresh fruits and vegetables was lower than in other neighborhoods. There were no differences in snack food availability.Conclusions. Other store types did not offset the relative lack of supermarkets in African-American neighborhoods in the provision of fresh produce, though they did for snack foods. Altering the mix of foods offered in such stores might mitigate these inequities. (C) 2010 Elsevier Inc. All rights reserved.
