Objective: To evaluate the relationship between the score of job satisfaction and depression.
Methods: A total of 2737 workers (2198 men and 539 women) participated. A 100-point scale for evaluating job satisfaction and the Occupational Depression Scale were used. A logistic regression analysis was applied with adjustment for age.
Results: The mean age of the subjects was 42.2 years for men and 36.0 years for women. When the group with the highest job satisfaction score was set as the control, the odds ratios and 95% confidence intervals for depression in the groups with the lowest and second lowest scores were 16.3 (7.51 to 35.2) and 5.90 (2.70 to 12.9) in men and 8.02 (1.78 to 36.1) and 5.68 (1.26 to 25.7) in women, respectively.
Conclusions: Job satisfaction was significantly associated with the depressive state, and causality should be clarified by a follow-up study.
