摘要

目的

探讨重庆城市老年人计时“起立-行走”测试(timed up and go test

TUGT) 的跌倒临界值，并分析其跌倒危险因素。

方法

于2019年6月至2020年2月，采用分层随机抽样法选取重庆城市3家医院、3个社区及3所养老院的老年人共1 200例作为受试者，收集人口学特征、文化程度、基础疾病、长期用药史及1年内跌倒史进行调查，采用多因素Logistic回归分析跌倒的独立危险因素；对受试者进行TUGT，应用受试者工作特征曲线确定TUGT临界值，并分析其对老年人跌倒预测的效能。

结果

TUGT组内相关系数呈高度相关(ICC=0.961，95%

：0.956~0.965)，Cronbach α系数为0.980；多因素Logistic回归分析显示：年龄≥80岁、长期服药史及TUGT时间发生跌倒的

值及95%

分别为1.591(1.079~2.344)、2.198(1.522~3.173)和1.725(1.598~1.861)(

0.05)；ROC曲线结果显示：受试者TUGT临界值为12.8 s，AUC为0.819(95%

：0.790~0.848)，敏感度为75.2%，特异度为74.7%。

结论

年龄≥80岁、长期服药史及TUGT时间＞12.8 s是重庆城市老年人跌倒风险的独立危险因素。

Abstract

Objective

To investigate the critical value of timed "up and go" test (TUGT) and analyze the risk factors of fall in Chongqing elderly.

Methods

A total of 1 200 elderly people were subjected by stratified random sampling from 3 hospitals

3 communities and 3 nursing homes in Chongqing. Their demographic characteristics

educational level

underlying diseases

long-term medication history and fall history within 1 year were investigated. Multivariate logistic regression analysis was used to analyze the influencing factors of falls. TUGT was performed on all the subjects

and receiver operating characteristic (ROC) curve was drawn to determine the critical value of TUGT

and its efficacy in predicting falls was analyzed.

Results

The intra-group correlation coefficient of TUGT was highly correlated (ICC=0.961

95%

: 0.956~0.965)

and the Cronbach α coefficient was 0.980. Multivariate logistic regression analysis showed that the

value and 95%

of fall occurred at age ≥80

long-term medication history and TUGT time were 1.591 (1.079~2.344)

2.198 (1.522~3.173) and 1.725 (1.598~1.861)

respectively (

0.05). ROC curve analysis indicated that the critical value of TUGT was 12.8 s

with an AUC of 0.819 (95%

: 0.790~0.848)

a sensitivity of 75.2%

and a specificity of 74.7%.

Conclusion

Age ≥80

long-term medication history and TUGT time > 12.8 s are independent risk factors for fall in Chongqing elderly population.
