摘　　要：目的基于Gobbens衰弱整合模式,探究农村老年人身体功能状况、营养状况在睡眠质量与衰弱间的中介效应。方法于2023年7—9月,采用多阶段分层整群随机抽样选取新疆农村地区年龄≥60岁的老年人,采用问卷调查和身体测量的方式进行调查研究。采用AMOS 28.0软件建立结构方程模型(SEM)并进行中介效应检验。结果(1)农村老年人衰弱得分为40.00(34.00,46.00),睡眠质量得分为7.00(5.00,9.00),身体功能状况得分为9.00(7.00,10.00),营养状况得分为13.00(12.00,14.00);(2)农村老年人睡眠质量得分与衰弱得分呈正相关,与身体功能状况和营养状况的得分呈负相关(r=0.405、-0.222、-0.125,P<0.001),身体功能状况得分与衰弱得分呈负相关,与营养状况得分呈正相关(r=-0.220、0.216,P<0.001),衰弱得分与营养状况得分呈正相关(r=-0.071,P=0.024);(3)身体功能状况及营养状况在睡眠质量和衰弱之间起中介作用,中介效应占总效应的15.76%。结论身体功能状况及营养状况在农村老年人睡眠质量和衰弱间起到中介作用,可通过早期识别睡眠问题,提高身体功能状况和营养状况,延缓甚至逆转衰弱的发生。Objective To explore the mediating effect of physical function and nutritional status between sleep quality and frailty in rural elderly people based on Gobbens frailty integration model.Methods From July to September 2023,multi-stage stratified cluster random sampling was used to select the elderly aged≥60 years old in rural areas of Xinjiang,and questionnaire survey and body measurement were used to investigate the study.AMOS 28.0 software was used to establish the structural equation model(SEM)and test the mediating effect.Results(1)Frailty scores of the rural elderly were 40.00(34.00,46.00),sleep quality scores were 7.00(5.00,9.00),physical function scores were 9.00(7.00,10.00),nutrition scores were 13.00(12.00,14.00);(2)The score of sleep quality of the rural elderly was positively correlated with the score of frailty,and negatively correlated with the score of physical function and nutritional status(r=0.405,-0.222,-0.125,P<0.001).The score of physical function was negatively correlated with the score of frailty,and positively correlated with the score of nutritional status(r=-0.220,0.216,P<0.001).Frailty score was positively correlated with nutritional status score(r=-0.071,P=0.024);(3)Physical function and nutritional status played a mediating role between sleep quality and frailty,accounting for 15.76%of the total effect.Conclusion Physical function status and nutritional status play an intermediary role in the sleep quality and frailty of the rural elderly.Through early identification of sleep problems,physical function status and nutritional status can be improved,delaying or even reversing the occurrence of frailty.
