Background Racial/ethnic minority older adults have worse stroke burden than non-Hispanic white and younger counterparts. Our academic-community partner team tested a culturally tailored 1-month (8-session) intervention to increase walking and stroke knowledge among Latino, Korean, Chinese, and black seniors. Methods and Results We conducted a randomized wait-list controlled trial of 233 adults aged 60 years and older, with a history of hypertension, recruited from senior centers. Outcomes were measured at baseline (T0), immediately after the 1-month intervention (T1), and 2 months later (T2). The primary outcome was pedometer-measured change in steps. Secondary outcomes included stroke knowledge (eg, intention to call 911 for stroke symptoms) and other self-reported and clinical measures of health. Mean age of participants was 74 years; 90% completed T2. Intervention participants had better daily walking change scores than control participants at T1 (489 versus -398 steps; mean difference in change=887; 97.5% CI, 137-1636), but not T2 after adjusting for multiple comparisons (233 versus -714; mean difference in change=947; 97.5% CI, -108 to 2002). The intervention increased the percent of stroke symptoms for which participants would call 911 (from 49% to 68%); the control group did not change (mean difference in change T0-T1=22%; 99.9% CI, 9-34%). This effect persisted at T2. The intervention did not affect measures of health (eg, blood pressure). Conclusions This community-partnered intervention did not succeed in increasing and sustaining meaningful improvements in walking levels among minority seniors, but it caused large, sustained improvements in stroke preparedness.

背景 与非西班牙裔白人和年轻患者相比,少数族裔老年患者的中风负担更重。我们的学术社区合作伙伴团队测试了一种经过文化调整的 1 个月(8 节)干预措施,以提高拉丁裔、韩国裔、华裔和非裔老年人的步行能力和中风知识。
方法和结果 我们对 233 名年龄在 60 岁及以上、有高血压病史的成年人进行了一项随机等待名单对照试验,这些成年人是从老年人中心招募的。在基线(T0)、1 个月干预后(T1)和 2 个月后(T2)测量结果。主要结果是计步器测量的步数变化。次要结果包括中风知识(例如,出现中风症状时拨打 911 的意图)以及其他自我报告和临床健康指标。参与者的平均年龄为 74 岁;90%的人完成了 T2。与对照组相比,干预组在 T1 时的日常步行变化评分更高(489 步对-398 步;变化差值为 887;97.5%CI,137-1636),但在调整了多次比较后,T2 时没有差异(233 步对-714 步;变化差值为 947;97.5%CI,-108 至 2002)。该干预措施增加了参与者拨打 911 报告中风症状的比例(从 49%增加到 68%);对照组没有变化(T0-T1 差值=22%;99.9%CI,9-34%)。这种效果在 T2 时仍然存在。该干预措施并未影响健康指标(如血压)。
结论 这项由社区合作伙伴参与的干预措施并没有成功地提高和维持少数族裔老年人的步行水平,但它导致了中风准备情况的大幅持续改善。
