目的:探讨养老机构老年人久坐行为、衰弱现状及其相关性。方法:2019年11月—2020年1月，采用分层抽样法选取太原市4所养老机构的181名老年人，采用一般资料调查表、老年人久坐行为问卷、Tilburg衰弱量表（TFI）对老年人的久坐时间和衰弱情况进行问卷调查。采用n t检验、方差分析、多重线性逐步回归分析对老年人久坐时间进行影响因素分析；采用Pearson相关分析法对老年人久坐时间、TFI总分进行相关性分析。n 结果:最终回收有效问卷172份，有效回收率为95.0%。172名养老机构老年人TFI总分为（6.10±3.01）分，衰弱发生率为69.2%（119/172），总久坐时间为（8.31±2.54）h/d。Pearson相关分析结果显示，TFI总分与总久坐时间呈正相关（n r=0.755，n P<0.01）。单因素分析结果显示，不同性别、年龄、文化程度、婚姻状况、居住情况、患病种数的老年人久坐时间比较，差异有统计学意义（n t/F值分别为2.480、18.998、33.101、-2.211、3.967、54.261；n P<0.05）。多重线性逐步回归分析结果显示，年龄、居住情况、文化程度、患病种数是老年人久坐时间的独立影响因素（标准化回归系数分别为0.286、-0.133、-0.155、0.500；n P<0.05），可解释46.8%的变异量。n 结论:养老机构老年人的久坐行为与衰弱状况存在相关性，老年人久坐时间越长，衰弱状况越严重，减少久坐时间有助于改善老年人衰弱情况。养老机构护理人员可从久坐行为方式角度进行护理干预，改善老年人的衰弱症状。“,”Objective:To explore the status quo of sedentary behavior and frailty of the elderly in nursing homes and analyze the correlation between them.Methods:A total of 181 elderly people in 4 nursing homes in Taiyuan from November 2019 to January 2020 were selected by stratified sampling method. General Data Questionnaire, Sedentary Behavior Questionnaire for The Elderly and Tilburg Frailty Index (TFI) were used to investigate the sedentary time and frailty of the elderly. The n t-test, analysis of variance and multiple linear stepwise regression analysis were used to analyze the influencing factors of sedentary time of the elderly, and Pearson correlation analysis was used to analyze the correlation between sedentary time and the total TFI score.n Results:In the end, a total of 172 valid questionnaires were recovered, with an effective recovery rate of 95.0%. The total TFI score of 172 elderly in nursing homes was (6.10±3.01) , the incidence of frailty was 69.2% (119/172) and the total sedentary time was (8.31±2.54) h/d. Results of Pearson correlation analysis showed that the total TFI score was positively correlated with the total sedentary time (n r=0.755, n P<0.01) . The results of univariate analysis showed that there were statistically significant differences in sedentary time of elderly people of different gender, ages, education levels, marital status, living status and number of illness (n t/F=2.480, 18.998, 33.101, -2.211, 3.967, 54.261; n P<0.05) . The results of multiple linear stepwise regression analysis showed that age, living status, education level and number of illness were independent factors influencing the sedentary time of the elderly (standardized regression coefficients were 0.286, -0.133, -0.155, 0.500;n P<0.05) , which could explain 46.8% of the variance.n Conclusions:There is a correlation between sedentary behavior of the elderly in nursing homes and their frailty conditions. The longer the elderly sit for a long time, the more severe their frailty conditions will be. Reducing the sedentary time will help improve the frailty conditions of the elderly. Nursing intervention can be carried out by nursing staff in nursing homes from the perspective of sedentary behavior to improve the frailty symptoms of the elderly.
