Abstract

Background

Older Black adults have high rates of physical function (PF) limitations. Physical activity (PA) is effective for improving PF and reducing mobility disability risk; however, community-based PA interventions focused on improving PF for older Black adults are lacking. Given the importance of churches as trusted institutions in Black communities, church-based interventions developed through community collaborations may help increase access to PA interventions.

Methods

Keep it Movin’ is a church-based cluster randomized controlled trial testing the effectiveness of a 24-week group-based (intervention arm) versus a self-guided (comparator arm) program in improving PF among Black adults aged ≥ 40 years with PF limitations (short physical performance battery [SPPB] score ≤ 9). A church-wide virtual walking program is available to congregants in both arms. The intervention arm receives weekly group-based classes held at the church that include education, goal setting, and structured PA (walking, lower-extremity strength, balance, and stretching). The comparator arm receives educational materials about PA appropriate for people with PF limitations. Outcomes are assessed at 6 (program completion) and 12 months (maintenance). The primary outcome is PF change as measured by the SPPB at 6 months. Secondary outcomes include change in moderate-to-vigorous PA, social support and self-efficacy for PA, quality of life, and self-reported PF. Factors related to successful adoption, implementation, and maintenance are assessed using the Reach, Effectiveness, Adoption, Implementation, and Maintenance (RE-AIM) framework.

Conclusion

This is the first study to evaluate the effectiveness of a group-based PA program delivered in Black churches to improve PF.

保持运动：以教堂为基础的体育活动计划的设计和方法，以改善中老年黑人的身体机能。

背景：黑人老年人的身体功能（PF）受限率很高。体力活动（PA）可有效改善身体功能并降低行动不便的风险；然而，以社区为基础、专注于改善黑人老年人身体功能的体力活动干预措施却很缺乏。鉴于教会作为黑人社区中值得信赖的机构的重要性，通过社区合作开发基于教会的干预措施可能有助于增加获得 PA 干预措施的机会：Keep it Movin'是一项以教堂为基础的群组随机对照试验，该试验测试了为期 24 周的集体计划（干预组）与自我指导计划（比较组）在改善年龄≥40 岁、有运动能力限制（短期体能测试 [SPPB] 得分≤9）的黑人成年人的运动能力方面的效果。两组参与者均可参加全教会范围内的虚拟步行计划。干预组每周在教堂举办一次小组课程，内容包括教育、目标设定和有组织的体育锻炼（步行、下肢力量、平衡和伸展）。对比组则接受适合有运动功能障碍的人的体育锻炼教育材料。结果在 6 个月（计划完成）和 12 个月（维持）时进行评估。主要结果是 6 个月时通过 SPPB 测定的 PF 变化。次要结果包括中度到剧烈运动的变化、社会支持和运动自我效能、生活质量以及自我报告的 PF。与成功采用、实施和维持有关的因素将使用 "到达、效果、采用、实施和维持"（RE-AIM）框架进行评估：这是第一项评估在黑人教堂开展的以小组为基础的锻炼计划对改善 PF 的有效性的研究。

期刊介绍： Contemporary Clinical Trials is an international peer reviewed journal that publishes manuscripts pertaining to all aspects of clinical trials, including, but not limited to, design, conduct, analysis, regulation and ethics. Manuscripts submitted should appeal to a readership drawn from disciplines including medicine, biostatistics, epidemiology, computer science, management science, behavioural science, pharmaceutical science, and bioethics. Full-length papers and short communications not exceeding 1,500 words, as well as systemic reviews of clinical trials and methodologies will be published. Perspectives/commentaries on current issues and the impact of clinical trials on the practice of medicine and health policy are also welcome.
