项目摘要

PROJECT SUMMARY 11.2 million (23.5%) older adults report difficulty traveling outside their homes, making limited transportation access a structural barrier to health. With over 7 million non-driving older adults and 7-10 non-driving years at the end of life, alternative transportation options are needed. Lack of public transit accessibility can disproportionally harm older adults with disabilities and may impact health behaviors, such as physical activity and social participation. Physical activity and social participation are key components of healthy aging, associated with cognition, quality of life, and mortality. To this end, identification of modifiable public transit features, and their impact on physical activity and social participation among older adults with disabilities is critically needed. The proposed research will examine the role of public transit on physical activity and social participation among older adults with and without disabilities. This research will collect primary data on public transit accessibility features and link them to the National Health and Aging Trends Study. Specifically, this research will address the following aims: 1) Examine if self-reported public transit use is associated with physical activity and social participation among older adults with and without disabilities, 2) Determine if the accessibility of public transit systems is associated with physical activity and social participation behaviors among older adults, 3) Test the hypotheses that public transit use partially mediates the link between public transit features and (a) physical activity and/or (b) social participation among older adults. The proposed use of NHATS, a rich, integrated data source will allow for investigation into whether public transit use interacts with disability status to result in differential physical activity and social participation (Aim 1); if the density and accessibility of public transit systems interact with disability status to affect physical activity and social participation (Aim 2); and the mechanism through which disability, public transit features, and public transit use shape physical activity and social participation among older adults (Aim 3). This research will examine if public transit system access is associated with physical activity and social participation among older adults with disabilities, a potential intervention target to optimize older adults’ ability to age in place. Identification of modifiable, upstream factors could reduce health disparities among this population group. The findings from this work will inform transportation development and planning about public transit systems which are inclusive of older adults with disabilities.

项目概要 1,120 万（23.5%）老年人表示外出出行有困难，导致交通运输受限超过 700 万不开车的老年人和 7-10 年不开车的人面临健康的结构性障碍。生命的尽头，缺乏公共交通可达性可能需要替代的交通选择。对残疾老年人造成不成比例的伤害，并可能影响身体活动等健康行为身体活动和社会参与是健康老龄化的关键组成部分，与认知、生活质量和死亡率相关。为此，确定可修改的公共交通。残疾老年人的特征及其对身体活动和社会参与的影响拟议的研究将探讨公共交通对身体活动和社交的作用。残疾和非残疾老年人的参与本研究将收集公众的主要数据。交通无障碍功能并将其与国家健康和老龄化趋势研究联系起来。研究将实现以下目标： 1) 检查自我报告的公共交通使用情况是否与残疾和非残疾老年人的身体活动和社会参与，2) 确定是否公共交通系统的可达性与身体活动和社会参与行为相关在老年人中，3) 检验以下假设：公共交通的使用部分调节了公共交通之间的联系老年人的交通特征和（a）身体活动和/或（b）社会参与。 NHATS 是一个丰富的综合数据源，可用于调查公共交通的使用是否与残疾状况导致身体活动和社会参与的差异（目标 1），如果密度和公共交通系统的无障碍性与残疾状况相互作用，影响身体活动和社交参与（目标 2）；以及残疾、公共交通功能和公共交通使用的机制塑造老年人的体育活动和社会参与（目标 3）。交通系统的使用与老年人的身体活动和社会参与有关残疾，是优化老年人就地养老能力的潜在干预目标。可修改的上游因素可以减少该人群之间的健康差异。这项工作将为交通发展和公共交通系统规划提供信息，这些系统具有包容性的残疾老年人。
