Frailty has been established as a risk factor for falls, and prefrailty also seems a risk; however, few studies have focused on the association between falls and each of the five components of frailty proposed by Fried. In the present study, we sought to elucidate the association between prefrailty and falls, and moreover, the association of frailty component with falls. Participants were community-dwelling older people who had cognitive complaints but not dementia (N = 447, male 54.6%). Prefrailty was defined as exhibiting one or two of the five Fried criteria. Frail individuals were excluded. Background characteristics were compared between the prefrail and robust groups, and multiple regression analysis was performed to investigate the associations between fall history within the past year and factors that were significantly different between the groups. We also performed logistic regression analysis with adjustment for age, education and gender to assess associations with frailty components. We found that prefrailty was associated with fall history. Depressed mood was also significantly associated with fall history. Among the five frailty criteria, exhaustion was significantly associated with falls. Prefrailty, especially the criteria of exhaustion, and depressed mood were associated with fall history.
衰弱已被确立为跌倒的危险因素，衰弱前期似乎也是一个危险因素；然而，很少有研究关注衰弱的五个组成部分与跌倒之间的关系，这些组成部分是由 Fried 提出的。在本研究中，我们试图阐明衰弱前期与跌倒之间的关系，以及衰弱组成部分与跌倒之间的关系。参与者是认知有问题但没有痴呆的社区居住老年人（N=447，男性 54.6%）。衰弱前期定义为表现出五个 Fried 标准中的一个或两个。排除了虚弱的个体。比较了衰弱前期和强壮组之间的背景特征，并进行了多元回归分析，以调查过去一年跌倒史与组间显著不同的因素之间的关系。我们还进行了逻辑回归分析，调整了年龄、教育和性别，以评估与脆弱性成分的关系。我们发现衰弱前期与跌倒史有关。抑郁情绪也与跌倒史显著相关。在五个脆弱性标准中，疲劳与跌倒显著相关。衰弱前期，尤其是疲劳标准和抑郁情绪与跌倒史有关。
