Policies targeting the built environment to increase physical activity may be ineffective without considering personal social networks. Physical activity and social network data came from the Montreal Neighborhood Networks and Healthy Aging Panel; built environment measures were from geolocation data on Montreal parks and businesses. Using multilevel logistic regression with repeated physical inactivity measures, we showed that adults with more favorable social network characteristics had lower odds of physical inactivity. Having more physical activity facilities nearby also lowered physical inactivity, but not in socially-isolated adults. Community programs that address social isolation may also benefit efforts to increase physical activity.
如果不考虑个人社交网络，针对建筑环境的政策来增加身体活动可能是无效的。身体活动和社交网络数据来自蒙特利尔社区网络和健康老龄化小组；建筑环境措施来自蒙特利尔公园和企业的地理位置数据。使用具有重复身体不活动措施的多层次逻辑回归，我们表明具有更有利的社交网络特征的成年人身体不活动的可能性较低。附近有更多的体育活动设施也降低了身体不活动的可能性，但对社交孤立的成年人则不然。解决社交孤立问题的社区计划也可能有利于增加身体活动的努力。
