This study examined the effects of a "community-based center" intervention to prevent the onset of functional disability among residents in disaster-affected areas.
We used data from a prospective cohort study conducted from 2010 to 2016 in Iwanuma City, Japan. Participants were community-dwelling independent adults aged ≥65 years. The exposure variable was the experience of using a community-based center. The outcome variable was functional disability onset. The average treatment effect on the treated (ATET) was estimated by adjusting for possible confounders. Additional analysis stratified by sex was conducted considering the sex differences in social participation rates.
Among 3794 participants (mean ± SD age = 72.9 ±5.3 years, 46.0% men), 196 (5.2%) used the community-based center, and 849 (22.4%) exhibited disability onset. Of those with functional disabilities, 40 (20.4%) used the community-based center, while 809 (22.5%) did not. The ATET for functional disability onset with community-based center activities across all participants were not significant (ATET: 0.51 years [95% confidence interval [CI] = -0.23; 1.27]). However, the direction of the effect of community-based center activities differed by sex (ATET: -0.14, 95% CI = -2.59; 2.31 for men [n = 18], and 0.66, 95% CI = 0.18; 1.16 for women [n = 178]). Women exhibited a 15.63% (95% CI = 3.58; 27.68) increase in the time until functional disability onset.
The use of community-based centers was associated with a longer period without functional disability in women. Geriatr Gerontol Int 2022; 22: 465-470.
本研究旨在探讨“社区中心”干预措施对预防受灾地区居民功能障碍发生的效果。
我们使用了 2010 年至 2016 年在日本岩沼市进行的一项前瞻性队列研究的数据。参与者为居住在社区、年龄≥65 岁的独立成年人。暴露变量为使用社区中心的经历。结局变量为功能障碍的发生。通过调整可能的混杂因素来估计治疗组的平均处理效应（ATET）。考虑到社会参与率的性别差异，对性别进行了分层分析。
在 3794 名参与者中（平均年龄±标准差为 72.9±5.3 岁，46.0%为男性），有 196 人（5.2%）使用了社区中心，849 人（22.4%）出现了功能障碍。在有功能障碍的患者中，有 40 人（20.4%）使用了社区中心，而有 809 人（22.5%）没有。所有参与者的社区中心活动对功能障碍发生的 ATET 不显著（ATET：0.51 年[95%置信区间（CI）：-0.23；1.27]）。然而，社区中心活动的效果方向因性别而异（男性：-0.14，95%CI：-2.59；2.31[n=18]，女性：0.66，95%CI：0.18；1.16[n=178]）。女性发生功能障碍的时间延长了 15.63%（95%CI：3.58；27.68）。
使用社区中心与女性无功能障碍期的延长有关。
