目标，我们利用一个年龄在45岁到84岁之间的成年人队列的数据，调查了娱乐资源的可用性是否与身体活动水平有关。数据来自多种族样本的2723名成年居民的纽约市，纽约州，巴尔的摩，马里兰州和福赛斯县，NC，链接到数据的娱乐资源的位置。我们测量了每个参与者住所0.5（0.8公里），1，2和5英里内资源的可用性（密度），并使用二项式回归来调查密度与体力活动的关系。在调整潜在的混杂因素后，居住在资源密度最高的地区的三分位参与者中的个体在典型的一周内比最低三分位的个体更有可能报告体力活动。娱乐资源的可用性和体育活动水平之间的关联并不存在最小的区域评估（0.5英里），但存在范围从1到5英里的区域。这些协会在少数民族和低收入居民中略强。资源的可用性可能是影响个体体育活动行为的几个环境因素之一。
Objectives., Using data from a large cohort of adults aged 45 to 84 years-old, we investigated whether availability of recreational resources is related to physical activity levels.Methods. Data from a multiethnic sample of 2723 adult residents of New York City, NY, Baltimore, Md; and Forsyth County, NC, were linked to data on locations of recreational resources. We measured the availability (density) of resources within 0.5 (0.8 km), 1, 2, and 5 miles of each participant's residence and used binomial regression to investigate associations of density with physical activity.Results. After adjustment for potential confounders, individuals in the tertile of participants residing in areas with the highest density of resources were more likely to report physical activity during a typical week than were individuals in the lowest tertile. Associations between availability of recreational resources and physical activity levels were not present for the smallest area assessed (0.5 miles) but were present for areas ranging from 1 to 5 miles. These associations were slightly stronger among minority and low-income residents.Conclusions. Availability of resources may be 1 of several environmental factors that influence individuals' physical activity behaviors.
