The purpose of this study was to examine whether the combined factors of physical performance, depressive symptoms and cognitive status are significantly associated with a history of falling in community-dwelling elderly. We performed a cross-sectional community-based survey, the OSHPE, from August 2011 to February 2012. In total, 5104 community-dwelling older adults aged 65 years and older (mean age 72.0) participated in the OSHPE. Participants underwent a grip strength (GS) test, chair stand test (CST), Timed Up & Go (TUG) test, Geriatric Depression Scale (GDS), and Mini-Mental State Examination (MMSE). Of the 4481 participants who met our requirements, 645 (14.4%) participants reported falling at least once in the past year. In a signal detection analysis (SDA), we found that the combination of GDS (≥6 points) and TUG (≥10.6 s) had the highest fall rate (36.4%), and the combination of GDS (<6 points) and CST (<11.1 s) had the lowest fall rate (11.7%). The highest fall rate group had a significantly higher odds ratio (OR) compared with the lowest fall rate group after adjusting for other potentially confounding variables [OR 3.12 (95% confidence interval (CI) 2.08-4.68) p<0.001]. The combination of depressive symptoms, TUG, and CST performance was strongly associated with a history of falling in community-dwelling elderly.
本研究旨在探讨身体机能、抑郁症状和认知状态等综合因素与社区老年人跌倒史是否显著相关。我们进行了一项横断面社区为基础的调查，即 OSHPE 研究，时间为 2011 年 8 月至 2012 年 2 月。共有 5104 名 65 岁及以上的社区老年人（平均年龄 72.0 岁）参加了 OSHPE。参与者接受了握力（GS）测试、椅子站立测试（CST）、计时起立行走测试（TUG）、老年抑郁量表（GDS）和简易精神状态检查（MMSE）。在符合我们要求的 4481 名参与者中，有 645 名（14.4%）参与者报告在过去一年中至少跌倒过一次。在信号检测分析（SDA）中，我们发现 GDS（≥6 分）和 TUG（≥10.6 秒）的组合跌倒率最高（36.4%），而 GDS（<6 分）和 CST（<11.1 秒）的组合跌倒率最低（11.7%）。调整其他潜在混杂变量后，最高跌倒率组的优势比（OR）显著高于最低跌倒率组[OR 3.12（95%置信区间（CI）2.08-4.68）p<0.001]。抑郁症状、TUG 和 CST 表现的综合与社区老年人的跌倒史密切相关。
