背景：很少有关于老年人的研究比较可能更受环境影响的女性步行和体力活动的环境相关性。在不同空间层面上的环境措施很少被比较。以前的研究结果通常是不一致的。方法：本研究从圣地亚哥县妇女健康倡议队列(N=5401)调查了老年妇女建筑环境和体力活动之间的关系。为参与者住址周围的3个缓冲区创建了建筑环境措施。线性回归分析调查了建筑环境特征与自我报告的体力活动和步行之间的关系。结果：总体步行与步行指数(β=0.050：半英里缓冲)、娱乐设施密度(β=0.036：1英里缓冲)和到海岸的距离(β=-0.064；P值和0.05)显著正相关。总体体力活动与到海岸的距离呈显著负相关，与娱乐设施密度呈正相关(Beta=0.036：1英里缓冲区；P<；0.05)。结论：虽然影响的规模很小，但我们确实在老年人中发现了步行能力和步行之间的重要关系，这支持了社区设计特征包括年龄友好元素的建议。更剧烈的身体活动可能发生在娱乐场所，而不是附近的街道。
Background: Few studies of older adults have compared environmental correlates of walking and physical activity in women who may be more influenced by the environment. Environmental measures at different spatial levels have seldom been compared. Findings from previous studies are generally inconsistent. Methods: This study investigated the relationship between the built environment and physical activity in older women from the Women's Health Initiative cohort in San Diego County (N = 5401). Built environment measures were created for 3 buffers around participants' residential address. Linear regression analyses investigated the relationship between the built environment features and self-reported physical activity and walking. Results: Total walking was significantly positively associated with the walkability index (beta = .050: half-mile buffer), recreation facility density (beta = .036: 1-mile buffer), and distance to the coast (beta = -.064; P-values < .05). Total physical activity was significantly negatively associated with distance to the coast and positively with recreation facility density (beta = .036: 1-mile buffer; P < .05). Conclusions: Although effect sizes were small, we did find important relationships between walkability and walking in older adults, which supports recommendations for community design features to include age friendly elements. More intense physical activity may occur in recreational settings than neighborhood streets.
