目的.评估食品环境往往需要使用商业上可用的数据。这些数据库中用于对食品店进行分类的方法各不相同，因此需要使用共同定义创建一种分类方法。这里描述了一种系统的策略，用于将出现在商业数据库中的食品商店和餐馆重新分类为区分健康选择可用性的类别。设计和设置。商业上可用的数据，包括名称，地址，北美行业分类系统代码，和相关的特点，获得了五个新泽西社区。一个重新分类的方法是使用标准和文献中的定义，根据健康选择的可用性对食品店进行分类。数据库中的信息通过系统的互联网和关键词搜索得到补充，从电话到食品出口。该方法导致原始数据中的622家超市/杂货店，183家便利店和148家专卖店重新分类为58家超市，30家杂货店，692家便利店和115家专卖店。从1485家全方位服务餐厅和506家有限服务餐厅的原始名单中重新分类为563家全方位服务餐厅和1247家有限服务餐厅。重新分类导致超市和杂货店的数量减少了不到七分之一，便利店的数量增加了三倍多，有限服务餐厅的数量增加了两倍--这比专门使用商业数据库产生的健康状况要差得多。结论。提出了一个明确的和可复制的战略，将商业数据库中的食品店重新分类为根据健康食品供应情况加以区分的类别。其目的是促进研究人员就公共卫生研究中用于表征不同类型食品店的定义达成共识。(Am J Health Promot 2011;26[2]：116-122.）
Purpose. Assessing food environments often requires using commercially available data. Disparate methods used for classifying food outlets in these databases call for creating a classification approach using common definitions. A systematic strategy for reclassifying food stores and restaurants, as they appear in commercial databases, into categories that differentiate the availability of healthy options is described here.Design and Setting. Commercially available data on food outlets including names, addresses, North American Industry Classification System codes, and associated characteristics was obtained for five New Jersey communities.Analysis. A reclassification methodology was developed using criteria and definitions from the literature to categorize food outlets based on availability of healthy options. Information in the database was supplemented by systematic Internet and key word searches, and from phone calls to food outlets.Results. The methodology resulted in 622 supermarket/grocery stores, 183 convenience stores, and 148 specialty stores in the original data to be reclassified into 58 supermarkets, 30 grocery stores, 692 convenience stores, and 115 specialty stores. Outlets from the original list of 1485 full-service restaurants and 506 limited-service restaurants were reclassified as 563 full-service restaurants and 1247 limited-service restaurants. Reclassification, resulted in less than, one-seventh the number of supermarkets and grocery stores, more than three times the number of convenience stores, and twice as many limited-service restaurants-a much less healthy profile than the one generated by using exclusively the commercial databases.Conclusion. An explicit and replicable strategy is proposed for reclassifying food outlets in commercial databases into categories that differentiate on the basis of healthy food availability. The intent is to contribute towards building a consensus among researchers on definitions used in public health research for characterizing different types of food outlets.
