Objectives: The aim of this study was to investigate the association between work-related stress and depressive symptoms among dental hygienists. Methods: This survey of dental hygienists was conducted in Gyeonggi province, South Korea. Total of 198 dental hygienists were interviewed in 2014. The occupational stress was evaluated by depression symptoms, which was assessed by the Beck Depression Inventory Scale. To estimate the odds ratio with 95% confidence intervals, logistic regression model was used. Results: Depressive symptoms were reported 46.0%(n=91) among dental hygienists. We found that the work-related stress increased with age, smoking(OR=5.16; 95% CI 1.73-15.3), and those who had the poor perceived health status(OR=4.22; 95% CI=1.50-11.86) was associated with the risk of depressive symptoms. After controlling potential confounders, such as dental hospital(OR=11.05; 95% CI=1.02-118.9), 5-7 years time since first employment(OR=0.15; 95% CI=0.03-0.89), and the group with the high job stress(OR=2.84; 95% CI=1.22-6.79) showed higher risks of depressive symptoms than did no depressive symptoms. Conclusion: Our findings suggest that the risk of depression appears to be related to age, smoking, self-reported health status, type of dental facility, years of practice and the stress of job.
