社区老年人衰弱综合征与久坐行为的相关性

Correlation between frailty and sedentary behavior in community elderly

目的探讨社区老年人衰弱与久坐行为的相关性。方法采用方便抽样法选取济南市两社区≥60岁老年人100例,通过衰弱身体表型量表、国际体力活动问卷(自填式长问卷)等调查工具了解社区老年人衰弱和久坐行为的现状,分析老年人衰弱与久坐行为的相关性。结果社区老年人衰弱发生率为14%,衰弱前期发生率为41%。社区老年人平均久坐时间为(6.59±2.03)h/d,其中非衰弱老年人久坐时间为(5.14±1.56)h/d,显著短于衰弱前期和衰弱期老年人[(7.34±1.53)h/d、(9.05±0.73)h/d,P<0.01]。Pearson相关分析显示,衰弱评分与久坐时间呈显著正相关(r=0.706,P<0.01)。Logistic回归分析结果显示,久坐时间是衰弱和4个衰弱表型(握力降低、自感疲乏、步速缓慢、低体力活动)的独立影响因素。结论长时间久坐是社区老年人发生衰弱的独立危险因素,社区老年护理工作者可以通过减少久坐行为来预防、改善和延缓老年衰弱的发生和发展。

Objective To explore the correlation between frailty and sedentary behavior in the community elderly.Methods A total of 100 patients aged≥60 years in two communities of Jinan city were sampled by convenient sampling method,and the status of frailty and sedentary behaviors of the elderly in the community were assessed by Frailty Body Phenotype Scale,International Physical Activity Questionnaire(self-filled long questionnaire),and the correlation between frailty and sedentary behaviors of the elderly was analyzed.Results The incidence rate of frailty was 14%,and the incidence rate of pre-frailty was 41%.The average sedentary time of the elderly was 6.59±2.03 h/day.Compared with non-frailty group(5.14±1.56 h/day),the sedentary time of pre-frailty group(7.34±1.53 h/day)and frailty group(9.05±0.73 h/day)was significantly prolonged(P<0.01).Pearson correlation analysis showed that Fried Frailty Phenotype Scale score was positive correlated with sedentary time(r=0.706,P<0.001).Logistic regression analysis showed that sedentary time was an independent influencing factor for frailty and 4 frailty phenotypes(low grip strength,self-fatigue,slow walking pace,low physical activity).Conclusions Sitting for a long time is an independent risk factor for frailty.Community geriatric nursing attendants could prevent the occurrence and dalay the development of frailty in the elderly by reducing sedentary behavior.
