Abstract：Objective:To explore the dose-response relationship between sleep duration and depressive symptoms among empty-nesters in China.Methods:A total of 2 321 empty-nesters aged 60 and above from the 2018 China Health and Retirement Longitudinal Survey were selected as the study subjects.Logistic regression and restricted cubic spline(RCS)models were used to analyze the dose-response relationship between sleep duration and depressive symptoms.Results:918 out of 2 321 empty-nesters were diagnosed with depressive symptoms,with detection rate of 39.55%.The detection rate of depressive symptoms in males was 31.25%,and in females was 49.81%.The detection rate of depressive symptoms in empty-nesters with sleep duration less than 5 hours was 62.47%,the detection rate of depressive symptoms in empty-nesters with sleep duration ranged from 5 to less than 7 hours was 41.15%,the detection rate of depressive symptoms in empty-nesters with sleep duration ranged from 7 to less than 9 hours was 29.55%,the detection rate of depressive symptoms in empty-nesters with sleep duration ranged from 9 to less than 11 hours was 33.81%,and detection rate of depressive symptoms in empty-nesters with sleep duration≥11 hours was 33.98%.The results of multivariate Logistic regression analysis showed that after adjusting for confounding factors,the detection rate of depressive symptoms in patients with sleep duration<5 hours and ranged from 5 to less than 7 hours were 2.529 times and 1.549 times higher than that in patients with sleep duration ranged from 7 to less than 9 hours,respectively(P<0.05).The RCS model analysis results showed that both overall analysis and gender stratification showed non-linear dose-response relationship between sleep duration and depressive symptoms among empty-nesters(overall trend P<0.01,non-linear test P<0.01).Conclusions:Insufficient sleep duration is a risk factor for depressive symptoms among empty-nesters.It is recommended to strengthen family and social support,so as to improve the sleep environment of empty-nesters,and reduce the risk of depressive symptoms among empty-nesters.
