There has been extensive conceptual and empirical work on the associations between social relations and health in recent years. However, the specific pathways through which social interactions impact on health have not been fully elucidated. The aim of this paper is to estimate associations between Leisure Time Physical Activity (LTPA) and social networks and support. Using data from a cross-sectional household survey in 40 disadvantaged lower super-output areas in London, we applied a multilevel model to investigate psychosocial and environmental determinants of physical activity in these populations. Our findings present a strong case for the influence of individual-level social networks on the level of LTPA, although the associations between the types of social support and LTPA were insignificant. We also found that crime rate was an important area-level correlates of LTPA.
近年来，人们在社会关系与健康之间的关联方面进行了广泛的概念和实证研究。然而，社会互动影响健康的具体途径尚未完全阐明。本文旨在估计休闲时间体力活动（LTPA）与社会网络和支持之间的关联。我们使用来自伦敦 40 个贫困下层超级区域的横断面家庭调查数据，应用多层次模型来调查这些人群中体力活动的心理社会和环境决定因素。我们的研究结果表明，个体层面的社会网络对 LTPA 的水平有很大的影响，尽管社会支持类型与 LTPA 之间的关联并不显著。我们还发现，犯罪率是 LTPA 的一个重要的区域层面相关因素。
