Project Summary/Abstract Background: Low-income midlife and older adults are disproportionately impacted by a range of chronic diseases and conditions that contribute to widening US health disparities and can be alleviated by regular physical activity (PA), yet are among the most inactive segments of the US population. Relatively few PA programs have been developed specifically with their needs in mind, most of these interventions remain primarily at the individual level of impact, and few such interventions take full advantage of the recognized impacts that built and social environmental factors have for increasing and sustaining daily PA. Objective: The major objective of this application is to enhance the potential scalability and sustainability of person-level PA interventions by leveraging the capacity of residents themselves as local data gatherers and solution generators for neighborhood environmental change. The primary aim of the proposed group-randomized trial is to systematically compare the sustained (two-year) multi-level impacts of a lay advisor-delivered, person-level PA intervention that has demonstrated efficacy and translatability (Active Living Every Day) [ALED Alone arm], versus the ALED program in combination with a novel neighborhood-level intervention, called Our Voice [ALED+Our Voice arm]. The Our Voice program teaches residents to use a simple mobile application to individually and collectively identify neighborhood barriers to daily PA. They then convey this information to local stakeholders and decision-makers in ways that can facilitate potentially sustainable neighborhood-level improvements in support of regular PA. Design: We propose to randomize 16 public housing sites serving low- income, ethnically diverse midlife and older adults to ALED Alone vs. ALED+Our Voice (n=265 participants per arm; total=530). We hypothesize that 2-year ALED+Our Voice participant PA, measured via accelerometry, will be higher than in ALED Alone. We also will evaluate the 2-year impacts of the two programs on neighborhood- level PA using a standardized PA observation tool (SOPARC-path form). Additional questions of interest include levels of PA change at intermediate measurement time points; exploration of intervention effects in relation to a set of putative multi-level mediators; and exploration of the relative costs of the two interventions in relation to PA changes. We will also explore, in both arms, ongoing participant communication with local stakeholders (i.e., local organizations, media) that can set the stage for continued social and built environment changes beyond the project period. IMPACT: If the preliminary evidence supporting the promise of the Our Voice community engagement program is confirmed, it will provide a means for expanding the impacts and reach of person-level PA interventions beyond participants themselves to the neighborhood setting. This can, in turn, provide a scalable means for potentially sustainable PA promotion across broader income groups of relevance to US health disparities.

项目总结/摘要 背景：低收入的中年和老年人受到一系列慢性疾病的不成比例的影响。 导致美国健康差距扩大的疾病和状况，可以通过定期 体育活动（PA），但在美国人口中最不活跃的部分。相对较少PA 虽然已经制定了专门针对他们需求的计划，但大多数干预措施仍然存在， 主要是在个人层面的影响，很少有这样的干预措施充分利用公认的 建筑和社会环境因素对增加和维持日常PA的影响。目的：通过 该应用程序的主要目标是增强个人级PA的潜在可扩展性和可持续性 通过利用居民本身作为当地数据收集者和解决方案的能力， 发电机的邻居环境变化。拟议的分组随机试验的主要目的是 系统地比较一个非专业人员提供的人员水平的持续（两年）多层次的影响， 已证明有效性和可转化性的PA干预（每天积极生活）[ALED单药组]， 与ALED计划结合一种名为“我们的声音”的新型社区干预相比， [ALED+我们的语音手臂]。“我们的声音”项目教居民使用一个简单的移动的应用程序， 单独和集体识别日常PA的邻居障碍。然后，他们将这些信息传达给 当地利益相关者和决策者的方式，可以促进潜在的可持续的邻里水平 改进对常规PA的支持。设计：我们建议随机抽取16个公共房屋用地， 收入，种族多样化的中年和老年人单独与ALED+我们的声音（n=265名参与者， 手臂;总数=530）。我们假设，通过加速度计测量的2年ALED+Our Voice参与者PA将 比单独使用ALED时更高。我们还将评估两个项目对社区的两年影响- 使用标准化的PA观察工具（SOPARC路径表）进行PA水平。其他有关问题 包括中间测量时间点PA变化水平; 与一套假定的多层次调解人的关系;以及探讨两种干预措施的相对成本， 与PA的变化有关。我们还将在两组中探索正在进行的参与者与当地 利益相关者（即，当地组织、媒体），为持续的社会和建筑环境奠定基础 项目期以外的变化。影响：如果初步证据支持我们的承诺， 语音社区参与计划得到确认，它将提供一种扩大影响的手段， 个人层面的PA干预的范围超出了参与者本身到社区环境。这个可以， 反过来，为在更广泛收入群体中推广具有潜在可持续性的巴勒斯坦权力机构提供了一种可扩展的手段， 与美国的健康差距有关。
