An Association of Life Satisfaction with Depressive Symptoms in Older Adults:The Mediating Role of Sleep Duration
摘要
Abstract
Objective:To analyze the relationship between life satisfaction,sleep duration,and depressive symptoms in older adults,and to explore the mediating role of sleep duration between life satisfaction and depressive symptoms. Methods:Questionnaire data from the 2020 China Health and Retirement Longitudinal Study(CHARLS)of older adults aged 60 and above were used.Spearman's rank correlation was used to examine the relationship between life satisfaction,sleep duration,and depressive symptoms.Logistic regression model was used to assess the relationships between variables,and a bootstrap test was used to examine the mediating role of sleep duration in the relationship between life satisfaction and depressive symptoms. Results:Spearman correlation analysis showed that life satisfaction(ρ=-0.265,p<0.05)and sleep duration(ρ=-0.207,p<0.05)were negatively correlated with depressive symptoms,while life satisfaction was positively correlated with sleep duration(ρ=0.106,p<0.05).Mediation analysis revealed that sleep duration played a partial mediating role in the relationship between moderate life satisfaction and depressive symptoms(effect size=-0.478,95%CI:-0.613 to-0.349)compared to those with low life satisfaction,and also between high life satisfaction and depressive symptoms(effect size=-0.649,95%CI:-0.796 to-0.512). Conclusion:Life satisfaction,sleep status,and depressive symptoms are significantly interrelated in older adults.Sleep duration played a partial mediating role between life satisfaction and depressive symptoms.关键词
