基于2012年行为风险因素监测系统的数据，本研究探讨了美国社区建筑环境与个人身体活动不足和肥胖的关联。多水平模型用于控制个人社会人口特征的影响。邻里变量包括建成环境、贫困水平和县级城市化程度。在建筑环境变量中，街道连通性较差和快餐店更突出的存在与更高的肥胖风险相关（特别是对于某些城市化水平的地区）。不同的城市化水平和性别的区域划分的数据子集的分析揭示了独立变量的影响的变异性，更是邻里变量比个人变量。这意味着一些肥胖风险因素具有地理特异性，并且在男性和女性之间存在差异。研究结果支持建筑环境在影响人们的健康行为和结果方面的作用，并促进公共政策，这些政策需要在地理上适应人口群体的多样性。
Based on the data from the Behavioral Risk Factor Surveillance System 2012, this study examines the association of neighborhood built environments with individual physical inactivity and obesity in the U.S. Multilevel modeling is used to control for the effects of individual socio-demographic characteristics. Neighborhood variables include built environment, poverty level and urbanicity at the county level. Among the built environment variables, a poorer street connectivity and a more prominent presence of fast-food restaurants are associated with a higher obesity risk (especially for areas of certain urbanicity levels). Analysis of data subsets divided by areas of different urbanicity levels and by gender reveals the variability of effects of independent variables, more so for the neighborhood variables than individual variables. This implies that some obesity risk factors are geographically specific and vary between men and women. The results lend support to the role of built environment in influencing people’s health behavior and outcome, and promote public policies that need to be geographically adaptable and sensitive to the diversity of demographic groups.
