目的 探讨步态和平衡功能对上海市社区65岁以上老年人衰弱的预测价值.方法 2022年12月至2023年4月在上海市社区招募65岁以上老年人414例,采用自设问卷、Fried衰弱表型量表、计时起立-行走测试(TUGT)、单腿站立测试(OLST)进行调查,对衰弱的影响因素进行多元Logistic回归分析.结果 衰弱前期和衰弱的发生率分别为62.8%和10.9%.居住农村、高龄、月均收入低、吸烟、久坐、无规律运动是社区老年人衰弱的风险因素;衰弱老年人TUGT时间提高(P<0.05),闭眼OLST时间降低(P<0.05).TUGT联合闭眼OLST预测衰弱的曲线下面积为0.846(95%CI 0.808～0.884,P<0.001),最佳阈值时敏感性0.726,特异性0.817.结论 步态和平衡功能可能是预测上海社区65岁以上老年人衰弱有意义的因子.
Abstract
Objective To explore the predictive value of gait and balance on the frailty in community-dwelling older adults aged 65 years and older in Shanghai.Methods A total of 414 community-dwelling older adults aged 65 years or older were recruited from Shanghai,from De-cember,2022 to April,2023.They were investigated with Fried's Frailty Phenotype Scale,Timed Up and Go Test(TUGT),one leg standing test(OLST)and self-designed questionnaire.The factors related to frailty were ana-lyzed using multivariate Logistic regression.Results The prevalence of pre-frailty and frailty were 62.8%and 10.9%,respectively.Living in rural residence,older age,low income,smoking,sedentary lifestyle and no regular exercise were the risk factors for frailty among com-munity-dwelling older adults.Time of TUGT increased,and time of closed eyes OLST descreased respectively in the frail older adults(P<0.05).The area under curve was 0.846(95%CI 0.808 to 0.884,P<0.001)as prediction for frailty using the combination of TUGT and closed eye OLST,with a sensitivity of 0.726 and a specificity of 0.817 at the optimal threshold.Conclusion Gait and balance may be a valuable predictor of frailty in community-dwelling older adults in Shanghai.
