种族/少数民族社区患与肥胖有关的慢性疾病的风险越来越高。要养成健康的饮食习惯，先决条件是要去商店购买价格实惠、营养丰富的食品。本研究的目的是评估加州洛杉矶三个不重叠但相似的低收入社区的食物获取、可用性和可负担性。方法采用基于社区的参与式研究方法，我们培训社区成员进行食品评估，1)绘制指定区域内零售食品网点的数量和类型，2)调查商店样本，以确定他们是否销售选定的健康食品以及这些食品的价格。我们使用描述性统计来总结研究结果。结果在3个社区的1273家餐饮场所中，1023家符合“食品零售网点”标准。最常见的零售食品店类型是快餐店（30%）和便利/酒类/街角商店（22%）。超市只占不到2%。便利商店/酒类商店/街角商店提供的健康食品不到选定健康食品的一半，而且出售健康食品的价格高于超市。在洛杉矶城市社区，人们很难进入销售平价健康食品的商店。健康食品战略应侧重于改变食品环境，以改善整体社区健康。
Introduction Racial/ethnic minority communities are at increasingly high risk for chronic diseases related to obesity. Access to stores that sell affordable, nutritious food is a prerequisite for adopting a healthful diet. The objective of this study was to evaluate food access, availability, and affordability in 3 nonoverlapping but similar low-income communities in urban Los Angeles, California. Methods Using a community-based participatory research approach, we trained community members to conduct a food assessment to 1) map the number and type of retail food outlets in a defined area and 2) survey a sample of stores to determine whether they sold selected healthful foods and how much those foods cost. We used descriptive statistics to summarize findings. Results Of the 1,273 food establishments mapped in the 3 neighborhoods, 1,023 met the criteria of "retail food outlet." The most common types of retail food outlets were fast-food restaurants (30%) and convenience/liquor/corner stores (22%). Supermarkets made up less than 2% of the total. Convenience/liquor/corner stores offered fewer than half of the selected healthful foods and sold healthful foods at higher prices than did supermarkets. Conclusions Access to stores that sell affordable healthful food is a problem in urban Los Angeles communities. Healthful food strategies should focus on changing food environments to improve overall community health.
