摘　　要：目的 探讨老年人睡眠障碍、抑郁与健康相关生命质量的关系,以及抑郁在睡眠障碍与健康相关生活质量的中介作用。方法 采用分层随机抽样法对河北省3 612名>60岁老年人进行调查,采用匹兹堡睡眠质量指数量表(PSQI)、简版老年抑郁量表(GDS-15)、简明健康生活质量量表(SF-36)收集相关资料。结果 老年人睡眠障碍与抑郁存在正相关关系(r=0.39,P<0.001),睡眠障碍、抑郁与健康相关生活质量存在负相关关系(r=-0.43,-0.40,P<0.001)。老年人睡眠障碍和抑郁对健康相关生活质量有负向预测作用(β=-0.26、-0.194、-0.43、-0.520);抑郁在老年人睡眠障碍和躯体健康相关生命质量之间起部分中介作用,中介效应占总效应39.29%;抑郁在老年人睡眠障碍和心理健康相关生命质量之间起部分中介作用,中介效应占总效应51.57%。结论 有睡眠障碍、抑郁的老年人健康相关生命质量较差,老年人睡眠障碍直接影响健康相关生命质量,也会通过抑郁对老年人躯体、心理健康相关生命质量产生间接影响。Objective To explore the relationship between sleep disorder,depression,and health-related quality of life in the elderly,and the mediating effect of depression on sleep disorder and health-related quality of life.Methods In total 3612 elderly people over 60 years old in Hebei Province were selected by stratified random sampling,and the related data were collected with the use of Pittsburgh sleep quality index(PSQI),the simplified geriatric depression scale(GDS-15),and concise health quality of life scale(SF-36).Results There was a positive correlation between sleep disorder and depression in the elderly(r=0.39,P<0.001),and a negative correlation between sleep disorder,depression,and health-related quality of life(r=-0.43 and-0.40,P<0.001).Sleep disorders and depression in the elderly had negative predictive effects on healthrelated quality of life(β=-0.26,-0.194,-0.43,and-0.520),and depression played a mediating role between sleep disorders and physical health-related quality of life in the elderly,accounting for 39.29%of the total effect.Depression played a mediating role between sleep disorders and mental health-related quality of life in the elderly,and the intermediary effect accounted for 51.57%of the total effect.Conclusion The health-related quality of life of the elderly with sleep disorder and depression is poor.Sleep disorder of the elderly not only directly affects the health-related quality of life,but also indirectly affects the physical and mental health-related quality of life of the elderly through depression.
