目的：比较低收入地区非种族超市和拉丁裔杂货店（tiendas）在几种健康与不健康食品的可得性、质量和成本方面的差异。设计：一项由三名独立观察员进行的横断面研究，对25家杂货店进行审计，这些杂货店被确定为80%参加儿童肥胖研究的拉丁裔家庭的主要食品来源。根据主要特征将商店分为超市和超市。环境：南圣地亚哥县。主题：10个城市和15个超市。结果：天门店数量小于超市（5个通道vs . 12个通道，P = 0.003）。新鲜农产品的可得性没有因商店类型而异；一种水果的质量不同。与大多数新鲜农产品相比，每单位（磅或片）的价格较低。与超市相比，满足美国农业部推荐的每周农产品食用量（基于8368千焦（2000千卡）/天的饮食）的成本要低3.00美元（P < 0.001）。一加仑脱脂奶的价格在田中明显更高（3.29美元对2.69美元，P = 0.005），而瘦牛肉（7%脂肪）在田中只有10%，而在10家超市中有67% （P = 0.01）。结论：在中国，购买更健康的乳制品和肉类的能力仍然存在障碍，而购买农产品的能力则并非如此。这些结果突出了趋势在改善低收入社区获得优质新鲜农产品方面的潜力。然而，需要努力增加健康乳制品和肉类产品的可及性和可负担性。
Objective: To compare non-ethnically based supermarkets and Latino grocery stores (tiendas) in a lower-income region with regard to the availability, quality and cost of several healthy v. unhealthy food items.Design: A cross-sectional study conducted by three independent observers to audit twenty-five grocery stores identified as the main source of groceries for 80% of Latino families enrolled in a childhood obesity study. Stores were classified as supermarkets and tiendas on the basis of key characteristics.Setting: South San Diego County.Subjects: Ten tiendas and fifteen supermarkets.Results: Tiendas were smaller than supermarkets (five v. twelve aisles, P = 0.003). Availability of fresh produce did not differ by store type; quality differed for one fruit item. Price per unit (pound or piece) was lower in tiendas for most fresh produce. The cost of meeting the US Department of Agriculture's recommended weekly servings of produce based on an 8368 kJ (2000 kcal)/d diet was $US 3.00 lower in tiendas compared with supermarkets (P < 0.001). The cost of 1 gallon of skimmed milk was significantly higher in tiendas ($US 3.29 v. $US 2.69; P = 0.005) and lean (7% fat) ground beef was available in only one tienda (10%) compared with ten (67%) supermarkets (P = 0.01).Conclusions: Barriers remain in the ability to purchase healthier dairy and meat options in tiendas, the same is not true for produce. These results highlight the potential that tiendas have in improving access to quality, fresh produce within lower-income communities. However, efforts are needed to increase the access and affordability of healthy dairy and meat products.
