The objective was to determine whether ethnic composition of neighborhoods is associated with number and type of food stores in an urban, Mexican American US community. Data were from a commercial food store data source and the US Census. Multivariate count models were used to test associations with adjustment for neighborhood demographics, income, and commercialization. Neighborhoods at the 75th percentile of percent Mexican American (76%) had nearly four times the number of convenience stores (RR=3.9, 95% CI: 2.2-7.0) compared with neighborhoods at the 25th percentile (36%). Percent Mexican American in the neighborhood was not associated with the availability of other food store types (supermarkets, grocery stores, specialty stores, convenience stores with gas stations) in the adjusted model. The impact of greater access to convenience stores on Mexican American residents' diets requires exploration.
目的在于确定美国城市墨西哥裔美国人聚居区的种族构成是否与食品店的数量和类型有关。数据来源于商业食品店数据源和美国人口普查。采用多元计数模型，在调整了社区人口统计学、收入和商业化因素后，检验了其与各因素的相关性。在调整后的模型中，墨西哥裔美国人比例排在第 75 百分位（76%）的社区的便利店数量几乎是排在第 25 百分位（36%）社区的四倍（RR=3.9，95%CI：2.2-7.0）。在调整后的模型中，社区中墨西哥裔美国人的比例与其他类型食品店（超市、杂货店、专卖店、带加油站的便利店）的供应情况无关。需要进一步研究增加对便利店的可及性对墨西哥裔美国居民饮食的影响。
