双重任务起立步行测试时间与老年抑郁风险的相关性分析

Correlation analysis between the test times for dual-task timed up-and-go test and geriatric depression risk in the elderly

目的探讨老年抑郁风险与双重任务下的起立步行(TUG)测试时间之间的相关性。方法招募在江苏南京社区居住的60岁及以上老年人193例,采用老年抑郁量表(GDS)进行老年抑郁筛查;分别进行单一任务TUG(TUG-single)测试、附加操作任务的TUG(TUG-manual)测试、附加认知任务的TUG(TUG-cognitive)测试。采用单因素方差分析TUG-single、TUG-manual、TUG-cognitive的差异。采用Pearson相关分析GDS得分与TUG-single,TUG-manualTUG-cognitive测试时间的相关性。结果平均TUG-cognitive时间和平均TUG-manual时间长于平均TUG-single时间(P<0.0001)。GDS得分越高,TUG-single测试时间越长,两者呈正相关0=0.2261,P=0.0016);GDS得分与TUG-manual测试时间呈正相关(r=0.2359,P=0.0010);GDS得分与TUG-cognitive测试时间也呈正相关0=0.1946,P=0.0067)。结论老年抑郁风险增加与TUG测试时间延长呈显著正相关-TUG测试可用于评估老年抑郁患者的功能性移动能力。

Objective To investigate the correlation between depression risk and the test time for dual-task timed up-and-go(TUG)test in the elderly.Methods A total of 193 elderly volunteers aged 60 years and over who lived in the Nanjing community of Jiangsu Province were recruited.The Geriatric Depression Scale(GDS)was used to screen for geriatric depression.The single-task TUG(TUG-single),TUG with additional operational tasks(TUG-manual)and TUG with additional cognitive tasks(TUG-cognitive)were tested in all subjects.The differences in test times taken to complete TUG-single,TUG-manual and TUG-cognitive tests were analyzed by ANOVA.The correlation of GDS scores with test time for TUG-single,TUG-manual,TUG-cogrdtive was analyzed by using Pearson's correlation.Results The average test times for TUG-cognitive and TUG-manual tests were longer than that for TUG-single test(P<0.0001).The higher the GDS score,the longer the TUG-single test time,with a significantly positive correlation between GDS and the test time for TUG-single(r=0.2261,P=0.0016).Similarly,GDS score showed significantly positive correlations with the test time for TUG-manual(r=0.2359,P=0.0010)and the TUG-cognitive test time(r=0.1946,P=0.0067).Conclusions The increase of depression risk is significantly and positively correlated with the prolongation of the TUG test time in the elderly.The TUG test can be used to assess the functional mobility in elderly patients with depression.
