诸如世卫组织老年友好城市等政策倡议认识到城市环境对于改善老年人健康的重要性，老年人的体力活动水平较低，而且更多地依赖当地社区。以前在这个年龄段的研究是有限的，很少使用PA或环境的客观衡量标准。我们使用横截面多水平线性回归分析，研究了客观测量的PA(Actigraph GT3X加速计)与建筑环境的多个维度之间的关联。暴露由一种新的基于脚的审计工具记录下来，该工具记录了与老年人PA相关的详细邻里特征和常规数据。来自英国20个城镇的两个国家队列的795名男性和638名女性被纳入分析范围，年龄在69岁到92岁之间。中度至重度PA(MVPA)的中位时间为27.9分钟(下四分位数：13.8，上四分位数：50.4)分钟。几乎没有证据表明任何物理环境领域(例如，通过潜在等级分析定义的道路和路径质量；公共汽车站数量；区域美学；商店和服务密度；绿地数量)与MVPA之间存在关联。然而，对地区水平的收入剥夺的分析表明，社会环境可能与这个年龄段的PA有关。尽管效应大小不能打折扣，但这项研究表明，老年人受当地物理环境的影响较小，而受社会环境因素的影响较大，这既反映了这一年龄段的功能异质性，也反映了他们活动空间的多样性。
Policy initiatives such as WHO Age Friendly Cities recognise the importance of the urban environment for improving health of older people, who have both low physical activity (PA) levels and greater dependence on local neighbourhoods. Previous research in this age group is limited and rarely uses objective measures of either PA or the environment. We investigated the association between objectively measured PA (Actigraph GT3x accelerometers) and multiple dimensions of the built environment, using a cross-sectional multilevel linear regression analysis. Exposures were captured by a novel foot-based audit tool that recorded fine-detail neighbourhood features relevant to PA in older adults, and routine data. 795 men and 638 women aged 69–92 years from two national cohorts, covering 20 British towns, were included in the analysis. Median time in moderate to vigorous PA (MVPA) was 27.9 (lower quartile: 13.8, upper quartile: 50.4) minutes per day. There was little evidence of associations between any of the physical environmental domains (eg, road and path quality defined by latent class analysis; number of bus stops; area aesthetics; density of shops and services; amount of green space) and MVPA. However, analysis of area-level income deprivation suggests that the social environment may be associated with PA in this age group. Although small effect sizes cannot be discounted, this study suggests that older individuals are less affected by their local physical environment and more by social environmental factors, reflecting both the functional heterogeneity of this age group and the varying nature of their activity spaces.
