Abstract
OBJECTIVE: To identify the prevalence of depression symptoms among employees in Shanghai and to explore the association of job stress factors with depression symptoms. METHODS: Seven kinds of occupations were selected as subjects by convenient cluster sampling. Job stresses were assessed by core job stress scale and depression symptoms were measured by epidemiological survey depression scale (CES-D). Logistic regression and hierarchical moderated multiple regression were used for analysis. RESULTS: There were 1301 participants completing the questionnaires. The CES-D score reached 16. 83 +/- 8.63 and depression symptoms were in 46.2% of participants. The CSE-D score and the rate of depression symptoms were varied in different age, education and occupational status. Personal hobbies were helpful to reduce depression symptoms (OR = 0.63, 95% CI = 0.48-0.82). High social supports and high rewards were protect factors for depression symptoms, and the ORs were 0.38 (95% CI= 0.25-0.55) and 0.35 (95% CI = 0.21-0.58) respectively. High over-commitment and effort-reward imbalance were risk factors for depression symptoms, and the ORs were 2.72 (95% CI = 1.76-4.21) and 2.77 (95% CI = 1.09-7.05) respectively. The effort-reward imbalance model is more powerful in predicting depression symptoms than the job demand-control model. CONCLUSION: Effort-reward imbalance and high over-commitment are the risk factors for depression symptoms, more social supports and having hobbies are the protect factors for depression symptoms.
