To examine pathways between individual, social, and environmental factors associated with leisure-time physical activity (LTPA) among Mexican-American adults.
Cross-sectional design using random-digit dialing to administer a structured telephone interview.
Mexican-American adults living in a U.S.-Mexican border community in San Diego, California (N = 672).
Data were collected on LTPA, demographic characteristics, acculturation, and other psychosocial and environmental factors associated with LTPA.
Structural equation modeling to test an a priori model of LTPA.
Participants were mostly female (71%) with a mean age of 39 years (SD = 13). Only 32% of participants met PA guidelines in their leisure time, with men (39%) meeting the guidelines more than women (29%). Using structural equation modeling, neighborhood factors, both social and environmental, showed indirect relationships with meeting PA guidelines through community resource factors. Significant covariates included marital status and age.
Individual, social, and environmental factors were associated with LTPA in this sample of Mexican-American adults. These findings can inform intervention studies that aim to increase LTPA in this population.
探讨与墨西哥裔美国成年人休闲时间体力活动（LTPA）相关的个体、社会和环境因素之间的途径。
使用随机数字拨号进行横断面设计，以进行结构化电话访谈。
加利福尼亚州圣地亚哥的美国-墨西哥边境社区的墨西哥裔美国成年人（N=672）。
收集关于 LTPA、人口统计学特征、文化适应以及与 LTPA 相关的其他心理社会和环境因素的数据。
结构方程模型用于测试 LTPA 的先验模型。
参与者主要为女性（71%），平均年龄为 39 岁（SD=13）。只有 32%的参与者在闲暇时间符合 PA 指南，男性（39%）比女性（29%）更符合指南。使用结构方程模型，邻里因素（包括社会和环境因素）通过社区资源因素与达到 PA 指南呈间接关系。显著的协变量包括婚姻状况和年龄。
在这个墨西哥裔美国成年人样本中，个体、社会和环境因素与 LTPA 相关。这些发现可以为旨在增加该人群 LTPA 的干预研究提供信息。
