Abstract:
Objective To explore the mediating role of sleep quality on the impact of occupational stress on depressive symptom among secondary industry occupational population. Methods A total of 895 secondary industry workers in Wuxi City were selected as the study subjects using the stratified random sampling method. The Core Occupational Stress Scale (COSS), Patient Health Questionnaire-9 items (PHQ-9) and Self-Filled Sleep Questionnaire (SSQ) were used to investigate their occupational stress, depressive symptom and sleep quality. Depressive symptom, occupational stress and sleep quality were respectively regarded as dependent variable, independent variable and mediating variable. Process program was used to construct a mediation model, and Bootstrap method was used to test its mediating effect. Results The median score and 25th, 75th percentile for occupational stress, depressive symptom and sleep quality was 43.0 (43.0, 48.0), 6.0 (3.0, 8.0) and 3.0 (1.0, 3.0) points. The detection rates of occupational stress, depressive symptom, sleep disorder were 28.7%, 63.0% and 38.8%, respectively. Spearman correlation analysis result showed that occupational stress was positively correlated with both depressive symptom and sleep quality (Spearman correlation coefficients of 0.46 and 0.49, all P<0.01). Bootstrap test result showed that occupational stress had positive effect on both depressive symptom and sleep quality (partial regression coefficients of 0.25 and 0.09, all P<0.01). Sleep quality partially mediated the impact of occupational stress on depressive symptom with the mediation effect value of 0.05 (95% confidence interval of 0.03-0.06), accounting for 20.0% of the total effect. Conclusion Both depression symptom and sleep quality are positively correlated with occupational stress in secondary industry occupational population. Sleep quality of this population partially mediate the impact of occupational stress on depressive symptom.
