The purpose of this study was to examine factors related to fear of falling (FOF) in elderly adults who showed no reduced performance regarding independent instrumental activities of daily living (IADL).
A total of 119 elderly adults participated in the study (mean age, 75.7±7.2 years, women, n=60). We investigated the prevalence of FOF, anamnesis, medications, body pain, and history of falls, the Geriatric Depression Scale, International Physical Activity Questionnaire, Life-Space Assessment (LSA). The Timed Up and Go test (TUG) and one-legged standing time were measured to evaluate physical performance. Participants were divided into elderly adults with FOF (FOF group) and those without FOF (non-FOF group). The unpaired t-test or chi-square test was used for group comparisons. Multiple logistic regression analysis was then performed to examine the factors associated with FOF.
The prevalence of FOF was 51.3% overall. The FOF group had a higher prevalence of anamnesis, body pain, and history of falls than the non-FOF group. The FOF group had lower LSA scores, longer durations on the TUG, and shorter durations on the one-legged standing test than the non-FOF group. On multiple logistic regression analysis, LSA (total score, 120 points) was significantly associated with FOF (odds ratio: 0.96, 95% confidence interval=0.93-0.99).
Fear of falling was significantly associated with life space in community-dwelling elderly adults who showed no reduced performance regarding IADL. In future, it will be necessary to clarify any possible causal relationship by longitudinal investigations.
本研究旨在探讨在独立进行工具性日常生活活动(IADL)能力未下降的老年人中,与跌倒恐惧(FOF)相关的因素。
共有119名老年人参与本研究(平均年龄75.7±7.2岁,女性60名)。我们调查了跌倒恐惧的患病率、既往史、用药情况、身体疼痛及跌倒史、老年抑郁量表、国际体力活动问卷、生活空间评估(LSA)。测量计时起立行走测试(TUG)和单腿站立时间以评估身体表现。参与者被分为有跌倒恐惧的老年人(跌倒恐惧组)和无跌倒恐惧的老年人(无跌倒恐惧组)。采用非配对t检验或卡方检验进行组间比较。然后进行多因素逻辑回归分析,以检验与跌倒恐惧相关的因素。
总体跌倒恐惧患病率为51.3%。跌倒恐惧组的既往史、身体疼痛和跌倒史患病率高于无跌倒恐惧组。跌倒恐惧组的LSA得分较低,TUG测试用时较长,单腿站立测试用时较短,均低于无跌倒恐惧组。在多因素逻辑回归分析中,LSA(总分120分)与跌倒恐惧显著相关(比值比:0.96,95%置信区间=0.93 - 0.99)。
在IADL能力未下降的社区居住老年人中,跌倒恐惧与生活空间显著相关。未来,有必要通过纵向研究来阐明可能存在的因果关系。
