"起立-行走"计时测试与老年衰弱患者跌倒风险的相关性研究

The correlation between the timed up and go test and fall risks in elderly frail patients

目的探讨"起立-行走"计时测试(TUG)与老年衰弱患者跌倒风险的相关性。方法选择2019年7-9月在北京医院心血管内科住院治疗的老年衰弱患者,采集患者的基本临床资料及跌倒相关信息,并分为跌倒组和未跌倒组,对比两组患者体质指数、TUG、4 m最大步行速度(4 m MWS)和Barthel指数的差异,检验TUG与各指标的相关性,采用多因素Logistic回归分析TUG与跌倒的相关性。结果最终纳入符合条件的研究对象96例,其中跌倒组35例、未跌倒组61例,跌倒组患者的平均TUG时间(16.45±6.44)s,明显长于未跌倒组(10.17±2.91)s,差异有统计学意义(t=-6.556,P<0.001);相关性分析结果显示,TUG与跌倒和4 m MWS均存在相关性(r=0.582、0.875,均P<0.001);多因素Logistic回归分析结果显示,TUG(OR=1.201,95%CI:1.111~1.470,P=0.004)和4 m MWS(OR=1.146,95%CI:1.063~1.244,P=0.015)是跌倒的危险因素。结论TUG与老年衰弱患者的跌倒风险具有相关性,推荐在临床上开展相关应用。

Objective To evaluate the correlation between the timed up and go(TUG)test and fall risks in elderly frail patients.Methods From July to September 2019,elderly frail patients who were treated at the cardiovascular department of our hospital were enrolled.Basic clinical data and fall-related information of patients were collected.Patients were divided into the fall group and the non-fall group.Results on the body mass index(BMI),TUG,4-meter maximum walking speed(4 m MWS)and Barthel index were compared between the two groups.The correlation between TUG and each indicator was examined.Multivariate Logistic regression analysis was used to analyze the correlation between the TUG and falls in elderly patients.Results A total of 96 eligible patients were enrolled,including 35 in the fall group and 61 in the non-fall group.The average TUG time was longer in the fall group than in the non-fall group(16.45±6.44 s vs.10.17±2.91 s,t=-6.556,P<0.001).The correlation analysis results showed that the TUG was correlated with falls and 4 m MWS(r=0.582 and 0.875,both P<0.001).Multivariate Logistic regression analysis showed that the TUG(OR=1.201,95%CI:1.111-1.470,P=0.004)and 4 m MWS(OR=1.146,95%CI:1.063-1.244,P=0.015)were risk factors for falls.Conclusions The TUG is correlated with fall risks in elderly frail patients and should be recommended as a routine test in clinical practice.
