应用起立行走计时测试评估中国老年人群运动功能及其与睡眠状况的相关性研究

Physical performance evaluated by the timed up and go test and its correlation with sleep in the elderly in China

目的探讨老年人睡眠状况对运动功能的影响,分析睡眠状况与运动功能的相关性。方法前瞻性多中心病例对照研究,招募北京市、天津市、海南省3个地区472例60~80岁老年人。通过面对面访谈收集研究对象的基本信息,现场进行起立-行走计时测试(TUG)评估运动功能;运动功能正常组106例(22.5%),异常组366例(77.5%)。应用匹兹堡睡眠质量指数(PSQI)量表和埃普沃斯思睡量表(ESS)评估研究对象的睡眠情况。对受试者运动功能的影响因素进行相关性分析。结果年龄、饮酒史、体质指数、既往疾病史、ESS评分、日间思睡及PSQI中睡眠质量、睡眠时间、睡眠效率、睡眠障碍、催眠药物、日间功能障碍评分是TUG值的影响因素。PSQI量表中睡眠时间、习惯性睡眠效率和ESS评分与运动功能呈正相关(均P<0.05)。Logistic回归分析结果显示,增龄(OR=1.125,95%CI:1.083~1.168,P<0.01)、有饮酒史(OR=0.482,95%CI:0.384~0.605,P<0.01)、体质指数超标(OR=1.663,95%CI:1.340~2.063,P<0.01)、高脂血症(OR=0.156,95%CI:0.077~0.318,P<0.01)、消化系统疾病(OR=0.154,95%CI:0.044~0.532,P<0.01)、使用催眠镇静药物(OR=0.415,95%CI:0.202~0.854,P<0.05)、日间思睡(OR=4.234,95%CI:2.800~6.403,P<0.01)及PSQI量表中的睡眠效率评分高(OR=1.425,95%CI:1.214~1.672,P<0.01)和睡眠障碍评分高(OR=3.356,95%CI:2.337~4.819,P<0.01)为老年人运动功能下降的危险因素。结论老年人群运动功能下降比例较高,运动功能与睡眠状况具有相关性。

ObjectiveTo investigate the effect of sleep on physical performance and the correlation between sleep quality and physical performance in the elderly.MethodsIn this prospective multicenter case-control study,472 elderly people aged 60-80 years were recruited from three regions in China,Beijing,Tianjin,and Hainan Province.Basic information of study participants was collected through face-to-face interviews,and physical performance of study participants was assessed by the time up and go(TUG)test on site,with 106 cases(22.5%)in the normal physical performance group and 366 cases(77.5%)in the abnormal group.The Pittsburgh Sleep Quality Index(PSQI)and the Epworth Sleepiness Scale(ESS)were applied to assess sleep quality of study subjects.Correlation analysis was performed to examine factors affecting subjects'physical performance.ResultsAge,history of alcohol consumption,BMI,past medical history,the ESS score,daytime sleepiness,and some components of PSQI,such as sleep quality,sleep efficiency,sleep disturbances,use of sleeping drugs and daytime dysfunction,were influencing factors of the TUG score.Two components of PSQI,sleep duration and habitual sleep efficiency,and the ESS score were positively correlated with physical performance.Logistic regression analysis showed that risk factors for decreased physical performance in the elderly included increased age(OR=1.125,95%CI:1.083-1.168,P<0.01),history of alcohol consumption(OR=0.482,95%CI:0.384-0.605,P<0.001),abnormally high body mass index(OR=1.663,95%CI:1.340-2.063,P<0.01),hyperlipemia(OR=0.156,95%CI:0.077-0.318,P<0.01),digestive system diseases(OR=0.154,95%CI:0.044-0.532,P<0.01),use of sleeping drugs(OR=0.415,95%CI:0.202-0.854,P<0.05),daytime sleepiness(OR=4.234,95%CI:2.800-6.403,P<0.01),a high habitual sleep efficiency score of PSQI(OR=1.425,95%CI:1.214-1.672,P<0.01)and a high sleep disturbances score in PSQI(OR=3.356,95%CI:2.337-4.819,P<0.01).ConclusionsThe incidence of physical performance decline is high in the elderly.There is a correlation between physical performance and sleep quality.
