SUMMARY:

Introduction: Common mental disorders (CMD) are characterized by anxiety, irritability, chronic fatigue and psychosomatic symptoms, being considered one of the main causes of illness in adults and a relevant public health problem, especially in Brazil, as they represent the third cause of retirement for disability and sickness benefits. Working conditions, number of work hours and the work organization are factors that influence the physical and mental health of workers, with several epidemiological studies pointing to shift and night work as a risk factor for chronic diseases, including mental disorders. However, most studies that assess shift work as a determinant of health come from high-income countries, being scarce in low- and middle-income countries such as Brazil. Objectives: The dissertation aimed to analyze the association between shift and night work and common mental disorders in baseline participants of the ELSA-Brasil cohort. Methods: This study is part of the Longitudinal Study of Adult Health (ELSA-Brasil), a Brazilian multicenter cohort study, which includes six Research Centers from different states (Bahia, Espírito Santo, Minas Gerais, Rio de Janeiro, Rio Grande do Sul and São Paulo). The manuscript resulting from this dissertation carried out a cross-sectional analysis with data from the baseline (year 2008) of the ELSA-Brasil. The sample comprised 11,679 active workers from six Brazilian states. CMD were evaluated using the Clinical Interview Schedule-Revised (CIS-R). Using a structured questionnaire, sociodemographic, behavioral, and occupational variables were evaluated. To examine the associations of interest, bivariate (independent variables and outcome) and multiple regression analyzes (association between shift work and CMD, adjusting for confounders) were performed using logistic regression, estimating Odds Ratios and 95% confidence intervals. Results: The manuscript, written as the main result of the dissertation, presented the findings and showed that the prevalence of CMD was 27.9% in the studied population. About 36.5% did shift work, 14.7% daytime work, 6.8% night work, and 15.0% mixed. Being female, being black or brown, being between 35 and 44 years old, having only completed high school, being separated or widowed, and exposed to job strain were associated with a higher prevalence of CMD. Night and mixed shift work (day and night), respectively, were associated with 21% (OR=1.21, 95%CI 1.02-1.42) and 18% greater chance (OR=1.18, CI95%1.05-1.33) of CMD, compared to those who did not do shift work. Day shift work was not associated with CMD. Stratified analyzes suggested that gender may be an effect modifier of the investigated association. Discussion: The results corroborate the findings of studies in high- and middle-income countries, highlighting shift work as a risk factor for CMD, which is related to the work organization in contemporary society. Other sociodemographic and work factors may contribute to the occurrence of CMD. Shift work, particularly when performed at night, can promote behavioral and lifestyle changes that affect mental health, and should be the focus of measures to prevent chronic conditions such as CMD. Longitudinal analyses, which consider the confounding and interaction factors included in this study, in addition to possible mediators, are still needed to deepen the understanding of the association between shift and night work and mental disorders, particularly in low- and middle-income countries like Brazil.
