背景：尽管有许多关于老年人跌倒恐惧（FoF）相关因素（如年龄和身体功能）的报道，但FoF与认知能力下降之间的关系尚不清楚。目的：确定老年FoF患病率与认知功能的关系。方法：参与者为101名老年人（平均年龄75.1岁，男性48.5%）。其中，54名老年人（53.4%）因存在FoF而被归类为恐惧组。年龄、性别、TUG、跌倒史、阿尔茨海默病评定量表、韦氏记忆量表-修正逻辑记忆I （WMS-LM I）、延迟记忆测试、数字符号编码、数字广度和语言流畅性作为潜在的相关因素。结果：Logistic回归分析显示，TUG[比值比（OR） 1.43, 95%可信区间（CI） 1.12-1.83；WMS-LM I （OR 1.20, 95% CI 1.07-1.35; p = 0.002）和跌倒史（OR 4.38, 95% CI 1.53-12.51; p = 0.006）与FoF独立相关。结论：结果表明，老年人自我报告的FoF患病率较低与记忆力下降有关。对FoF的不敏感可能是伴随记忆衰退的心理变化的特征之一。
Background:In spite of a number of reports about various factors associated with the fear of falling (FoF) among older adults (such as age and physical function), the relationship between FoF and cognitive decline remains unclear.Objective:To determine which cognitive function is related with the prevalence of FoF in older adults.Methods:Participants were 101 older adults (mean age 75.1 years; 48.5% males). Of these, 54 older adults (53.4%) were classified as the fear group on the basis of the presence of FoF. Age, gender, the Timed Up and Go test (TUG), fall history, the Alzheimer’s Disease Assessment Scale, the Wechsler Memory Scale-Revised-Logical Memory I (WMS-LM I), the delayed memory test, digit symbol coding, digit span and verbal fluency were measured as potential relevant factors.Results:Logistic regression analysis revealed that TUG [odds ratio (OR) 1.43, 95% confidence interval (CI) 1.12–1.83; p = 0.004], WMS-LM I (OR 1.20, 95% CI 1.07–1.35; p = 0.002) and fall history (OR 4.38, 95% CI 1.53–12.51; p = 0.006) were independently associated with FoF.Conclusions:The results suggest that a lower prevalence of self-reported FoF is associated with memory decline among older adults. Insensitivity to FoF may be one of the characteristics of psychological change with memory decline.
