Investigating the role of public transit on health behaviors among older adults with disabilities

项目摘要 11.2 100万（23.5%）的老年人报告说，出门旅行有困难， 进入健康的结构性障碍。超过700万不开车的老年人和7-10年不开车的年龄， 在生命的尽头，需要替代的运输选择。缺乏公共交通可达性， 对残疾老年人造成精神伤害，并可能影响健康行为，如身体活动 和社会参与。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，确定可改装的公共交通 特点，及其对残疾老年人身体活动和社会参与的影响， 急需的。拟议的研究将研究公共交通对身体活动和社会的作用。 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。具体来说， 研究将解决以下目标：1）检查自我报告的公共交通使用是否与 身体活动和社会参与的老年人与残疾和非残疾，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有关 3）检验公共交通使用部分介导公共交通与老年人之间的联系的假设， 老年人的交通特征和（a）身体活动和/或（B）社会参与。提出利用 NHATS是一个丰富的综合数据源，可以调查公共交通使用是否与 残疾状况导致不同的身体活动和社会参与（目标1）;如果密度和 公共交通系统的可达性与残疾状况相互作用，影响身体活动和社会 参与（目标2）;以及残疾、公共交通特征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）。这项研究将研究公共 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，一个潜在的干预目标，以优化老年人的能力，年龄在地方。鉴定 可以改变的上游因素可以减少这一人口群体的健康差距。的结果 这项工作将为交通发展和规划提供有关包容性公共交通系统的信息， of elderly老年adults成人with disabilities残疾.

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.
