The predictive power of three intersecting environmental dimensions (built structures, social infrastructure, and social capital) on late-life walking was investigated, conceptually based on the ecological framework of place, which posits that a living environment is simultaneously a physical place, a social place, and a set of social bonds. Multilevel models were used to examine the extent to which environments, defined as interactions of the social and material environmental dimensions, reliably predicted walking for transportation among U.S. adults aged 60 years or older in the 2015 National Health Interview Survey (n = 11,180). Random intercepts representing 221 environments showed an intraclass correlation of 21%, indicating high levels of between-environment variance in walking. Social infrastructure had the highest predictive power for walking, followed by material structures and social capital. Synergistic interventions that incorporate the intersecting nature of the sociomaterial environment may be most effective in promoting physical activity in later life.
本研究从场所生态框架出发，探讨了三个相互交叉的环境维度（建筑结构、社会基础设施和社会资本）对老年人步行能力的预测作用，该框架认为生活环境既是物质场所，也是社会场所，还是一套社会关系。本研究采用多层次模型，分析了 2015 年美国国家健康访谈调查中年龄在 60 岁及以上的成年人的环境（定义为社会和物质环境维度的相互作用）在多大程度上能够可靠地预测用于交通的步行能力（n=11180）。221 个环境的随机截距显示出 21%的组内相关，表明步行能力在环境之间存在高度的差异。社会基础设施对步行的预测能力最高，其次是物质结构和社会资本。结合社会物质环境交叉性质的协同干预措施可能最有效地促进老年人的身体活动。
