邻里建筑环境与步行活动的关联越来越受到关注，尽管大多数研究都依赖于建筑环境的主观测量，很少有人研究建筑环境与老年人步行之间的关系。这项2001年的研究探讨了当地社区的客观测量特征和步行活动之间的关系，在波特兰，俄勒冈州的546个社区居住的老年人的样本。一个地理信息系统被用来获得每个参与者的住所周围四分之一英里（0.4公里）和半英里（0.8公里）半径内的建筑环境的措施。多层次回归分析被用来研究建筑环境与步行行为的关联。在这组老年人中，没有观察到建筑环境与行走或不行走的可能性之间存在关联。然而，在那些报告有一定程度步行活动的参与者中，每周平均步行时间与当地社区的汽车交通量和商业机构数量显着相关。这些研究结果表明，建筑环境可能对老年人是否走路并不起重要作用，但在那些走路的人中，它与活动水平的增加有关。
The association of neighborhood built environment with walking activity has received growing attention, although most studies have relied upon subjective measures of the built environment and few have examined the relation between built environment and walking among older adults. This 2001 study examined the relation between objectively measured characteristics of the local neighborhood and walking activity among a sample of 546 community-dwelling older adults in Portland, Oregon. A geographic information system was used to derive measures of the built environment within a quarter-mile (0.4 km) and half-mile (0.8 km) radius around each participant's residence. Multilevel regression analysis was used to examine the association of built environment with walking behavior. No association between built environment and the likelihood of walking or not walking was observed in this cohort of older adults. However, among those participants who reported some degree of walking activity, average time spent walking per week was significantly associated with amount of automobile traffic and number of commercial establishments in their local neighborhood. These findings suggest that built environment may not play a significant role in whether older adults walk, but, among those who do walk, it is associated with increased levels of activity.
