背景资料：改善社区环境以支持步行和骑自行车是提高人口体育活动水平的一种有前途的方法。然而，很少有研究同时评估的看法和客观测量的环境因素和他们的相对关联与交通或休闲体育activity.Methods：对于这个横断面研究，高收入和低收入的研究领域中选择的人口普查区在圣路易斯MO（“低步行”城市）和萨凡纳GA（“高步行”城市）。2002年2月至6月，1068名成年人的电话调查提供了感知环境和体力活动行为的措施。在此时间范围内，通过对所有街道段（n = 1158）的环境审计收集了客观措施。这些措施被总结使用400米的缓冲区周围的每个受访者。邻里特色包括土地利用环境、交通环境、游憩设施、美学、社会环境等。邻里功能和交通和娱乐为基础的activity.Results之间的关联进行了检查：调整后的年龄，性别和教育，交通活动与人行道水平和感知和客观的邻里美学的客观措施呈负相关。它与感知和客观测量的目的地和公共交通数量、感知的自行车道使用权以及社区活跃人群的客观数量呈正相关。休闲活动是积极相关的感知访问娱乐设施和客观措施的吸引力feature.Conclusions：这些研究结果表明，体育活动的交通或娱乐与不同的感知和客观的环境特征。对这些功能的修改可能会改变暴露于它们的居民的身体活动行为。
Background: Enhancing community environments to support walking and bicycling serves as a promising approach to increase population levels of physical activity. However, few studies have simultaneously assessed perceptions and objectively measured environmental factors and their relative association with transportation or recreational physical activity.Methods: For this cross-sectional study, high- and low-income study areas were selected among census tracts in St. Louis MO ("low-walkable" city) and Savannah GA ("high-walkable" city). Between February and June 2002, a telephone survey of 1068 adults provided measures of the perceived environment and physical activity behavior. In this timeframe, objective measures were collected through environmental audits of all street segments (n = 1158). These measures were summarized using 400-m buffers surrounding each respondent. Neighborhood characteristics included the land use environment, transportation environment, recreational facilities, aesthetics, and social environment. Associations were examined between neighborhood features and transportation- and recreation-based activity.Results: After adjusting for age, gender, and education, transportation activity was negatively associated with objective measures of sidewalk levelness and perceived and objective neighborhood aesthetics. It was positively associated with perceived and objectively measured number of destinations and public transit, perceived access to bike lanes, and objective counts of active people in the neighborhood. Recreational activity was positively associated with perceived access to recreational facilities and objective measures of attractive features.Conclusions: These findings indicate that physical activities for transportation or recreational are associated with different perceived and objective environmental characteristics. Modifications to these features may change the physical activity behavior of residents exposed to them.
