背景：经验研究发现，环境因素影响个体的体重状况超过个体的社会经济特征。鉴于肥胖程度的不断增加，研究人员正在研究食物环境如何导致不健康的体重状况。一个重要的变化，这种环境是越来越多的可用性远离家庭的饮食场所，如restaurs.Methods：本研究分析了在美国各县的餐厅环境和体重状况之间的关系。2002-2006年行为风险因素监测系统（N= 714，054）的个人数据与2002年美国经济普查的餐馆数据相关联。快餐店和全方位服务的餐厅密度，沿着与餐厅组合（快餐店的比例，全方位服务的餐厅），进行了assessed.Results：快餐店的密度和较高的比例，快餐店的全方位服务的餐厅与较高的个人水平的体重状况（BMI和肥胖的风险）。与此相反，更高密度的全方位服务的餐厅与较低的重量status.Conclusions：区域级的餐厅组合出现了一个重要的相关性的重量状态，与组件的餐厅环境表现出差异的协会。因此，相对于其他远离家庭的选择，快餐的可用性似乎对不健康的体重结果很重要。高密度的全方位服务的餐馆的地区是一个更健康的饮食环境的指示，这表明有必要研究在不同类型的餐馆提供的食物的比较健康。未来的前瞻性研究需要描绘因果关系的途径。
Background: Empiric studies find that contextual factors affect individual weight status over and above individual socioeconomic characteristics. Given increasing levels of obesity, researchers are examining how the food environment contributes to unhealthy weight status. An important change to this environment is the increasing availability of away-from-home eating establishments such as restaurants.Methods: This study analyzed the relationship between the restaurant environment and weight status across counties in the United States. Individual data from the 2002-2006 Behavioral Risk Factor Surveillance System (N=714,054) were linked with restaurant data from the 2002 U.S. Economic Census. Fast-food and full-service restaurant density, along with restaurant mix (the ratio of fast-food to full-service restaurants), were assessed.Results: Fast-food restaurant density and a higher ratio of fast-food to full-service restaurants were associated with higher individual-level weight status (BMI and the risk of being obese). In contrast, a higher density of full-service restaurants was associated with lower weight status.Conclusions: Area-level restaurant mix emerged as an important correlate of weight status, with components of the restaurant environment exhibiting differential associations. Hence, it is the availability of fast-food relative to other away from-home choices that appears salient for unhealthy weight outcomes. Areas with a high density of full-service restaurants were indicative of a more healthful eating environment, suggesting a need for research into the comparative healthfulness of foods served at different types of restaurants. Future prospective studies are required to delineate causal pathways.
