This paper examines the association between neighborhood active living potential and walking among middle-aged and older adults. A sample of 2,614 (61.1% women) persons aged 45 years or older and living in one of 112 census tracts in Montreal, Canada, were recruited between February and May of 2005 to participate in a 20-minute telephone survey. Data were linked to observational data on neighborhood active living potential in the 112 census tracts and analyzed through multilevel modeling. Greater density of destinations in the census tract was associated with greater likelihoods of walking for any reason at least 5 days per week for at least 30 minutes (odds ratio = 1.53, 95% confidence interval: 1.21, 1.94). Associations were attenuated but remained statistically significant after controlling for socioeconomic, health, lifestyle, and other physical activity characteristics. Sensitivity analyses showed that associations were robust across smaller and larger volumes of walking. No associations were found between dimensions of neighborhood active living potential and walking for recreational reasons. The authors conclude that a larger number and variety of neighborhood destinations in one's residential environment are associated with more walking and possibly more utilitarian walking among middle-aged or older adults.
本文探讨了社区积极生活潜力与中老年人步行之间的关联。2005年2月至5月期间，在加拿大蒙特利尔的112个人口普查区中，招募了2614名年龄在45岁及以上的居民（女性占61.1%）参与一项20分钟的电话调查。数据与这112个人口普查区的社区积极生活潜力的观测数据相关联，并通过多层次模型进行分析。人口普查区内更高的目的地密度与每周至少5天、每次至少30分钟因任何原因步行的可能性增加相关（优势比=1.53，95%置信区间：1.21，1.94）。在控制了社会经济、健康、生活方式和其他身体活动特征后，这种关联有所减弱，但仍具有统计学意义。敏感性分析表明，无论步行量大小，这种关联都很稳健。未发现社区积极生活潜力的维度与出于娱乐目的的步行之间存在关联。作者得出结论，居住环境中更多数量和种类的社区目的地与中老年人更多的步行以及可能更多的实用性步行相关。
