Association between physical hazardous agent exposure and mental health in the Korean working population: the 5th Korean Working Conditions Survey

초록

Background: Mental health problems are emerging issues in occupational safety and health, whereas the findings on the relationship between physical hazards and mental health are not consistent. The aim of our study was to investigate the association between physical hazard exposure and mental health outcomes including depression and anxiety. Methods: We included 48,476 participants from the fifth Korean Working Conditions Survey (KWCS) in this study. The chi(2) test and logistic regression analyses were conducted to assess the association between physical hazard exposures and mental health. All statistical analyses were performed sex-specifically. Results: In logistic regression analysis, the odds ratios (ORs) of depression were significantly increased in male workers who were exposed to vibration (severe OR: 1.54, 95% confidence interval [CI]: 1.21-1.95) and noise (severe OR: 1.93, 95% CI: 1.49-2.48) whereas the ORs of depression were not significant in female workers from vibration (severe OR: 0.86, 95% CI: 0.50-1.38) or noise exposure (severe OR: 1.39, 95% CI: 0.84-2.17). The ORs of anxiety were significantly increased in male workers with vibration (severe OR: 1.76, 95% CI: 1.43-2.15) and noise exposure (severe OR: 2.12, 95% CI: 1.69-2.63) whereas the OR between vibration and anxiety (severe OR: 1.45, 95% CI: 0.91-2.21) was not significant in female workers. High or low temperature exposure had significant associations with depression and anxiety in both male and female subjects. Conclusions: Results of our study suggest that physical hazard exposures may be associated with increased risk of mental health problems including depression and anxiety. These associations are more prominent in male workers in comparison with female workers.
