Occupational factors associated with major depressive disorder: A Brazilian population-based study
Abstract
Background There have been very few studies exploring the occupational risk factors for major depressive disorder (MDD) in the working populations in Latin America. The aim of this study was to explore the associations between a large set of occupational factors and MDD in the Brazilian working population.Methods The study was based on the cross-sectional data from the Brazilian National Health Survey, 2013. 60,202 people were interviewed (response rate: 91.9%). Among them, 36,442 were working, 19,450 men and 16,992 women. MDD was measured using the diagnostic algorithm (DSM-IV criteria) of the PHQ-9. Occupational factors included job characteristics, working time factors, psychosocial work stressors and physico-chemical exposures. Logistic regression models were performed and adjusted for sociodemographic factors. All analyses were conducted using weighted and stratified data by gender.Results The following occupational factors were associated with a higher risk of MDD: working part time (≤20 h a week) and stress at work for both genders, workplace violence, intense physical activity, exposure to noise and chemicals among women, and prolonged exposure to sun among men. Associations of stress and violence at work with MDD were particularly strong.Limitations Cross-sectional study design, healthy worker effect and reporting bias may have impacted the results.Conclusions This study, one of the first studies among the Brazilian working population, showed that psychosocial work stressors were the strongest risk factors for MDD. Physico-chemical exposures deserve more attention in association with MDD. Prevention policies oriented toward the work environment may help to prevent depression at the workplace.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
