目标。为了调查步行能力与肥胖之间的关系，我们研究了居住在马里兰州巴尔的摩市不同种族和社会经济构成社区的成年人。我们对3493名参与者进行了一项横断面研究，这些参与者来自“多样性社区的健康老龄化”研究。我们使用行人环境数据扫描来测量研究参与者居住的34个不同种族和社会经济构成的社区的步行性。验证性因子分析用于确定步行性评分。采用多水平模型来确定步行能力与肥胖之间关系的流行率。在以白人和高社会经济地位（SES）为主的社区中，与生活在低可步行性社区的个体相比，居住在高可步行性社区的个体的肥胖患病率较低，在调整了个人层面的人口统计学变量后(患病率比-[PR]=0.58； P=
Objectives. To investigate the association between walkability and obesity, we studied adults residing in Baltimore City, Maryland, in neighborhoods of varying racial and socioeconomic composition.Methods. We conducted a cross-sectional study of 3493 participants from the study Healthy Aging in Neighborhoods of Diversity across the Life Span. We used the Pedestrian Environment Data Scan to measure neighborhood walkability in 34 neighborhoods of diverse racial and socioeconomic composition in which the study participants lived. Confirmatory factor analysis was used to determine walkability scores. Multilevel modeling was used to determine prevalence ratios for the association between walkability and obesity.Results. Among individuals living in predominately White and high-socioeconomic status (SES) neighborhoods, residing in highly walkable neighborhoods was associated with a lower prevalence of obesity when compared with individuals living in poorly walkable neighborhoods, after adjusting for individual-level demographic variables (prevalence ratio-[PR]=0.58; P=
