Abstract
The aim of the present study was to summarize the prevalence of common mental disorders (CMD) among Brazilian workers through a systematic review and meta-analysis. Searches were conducted in SciELO, LILACS, PubMed, Scopus, and Web of Science. Articles were included if they had; an observational design, a sample of Brazilian workers, used a validated instrument and cut-off to assess CMD, and provided the prevalence value. A random-effect meta-analysis using professional categories as subgroups and a meta-regression were conducted. In total, 89 studies were included, with a total of 56,278 workers from 26 professional categories. The overall pooled prevalence of CMD was 0.30 (95%CI: 0.27-0.34), varying from 0.07 to 0.58. Professional categories that presented higher prevalences of CMD were: Prostitutes 0.58 (95%CI: 0.51-0.65), Social Educators 0.54 (95%CI: 0.50-0.59), Banking Workers 0.45 (95%CI: 0.44-0.47), Ragpickers 0.45 (95%CI: 0.40-0.49), and Teachers 0.40 (95%CI: 0.32-0.48). No other variable in addition to profession was associated with prevalence of CMD in the meta-regression analysis. Workers from the most affected professional categories should be monitored to prevent social, occupational, and health impairment from CMD.

The aim of the present study was to summarize the prevalence of common mental disorders (CMD) among Brazilian workers through a systematic review and meta-analysis
The question that guided the present systematic review was: What is the prevalence of common mental disorders among Brazilian workers? According to the PICOS model, the following eligibility criteria were adopted: Participants (P): Adult Brazilian workers; Intervention (I): Not applicable; Comparison (C): Not applicable; Outcome (O): Prevalence of common mental disorders assessed by a validated questionnaire and cut-off; Study (S): Cross-sectional or cohort
Summary
Common mental disorders are constituted by depressive and anxiety disorders[1]. The pooled prevalence of common mental disorders in the worldwide general population is high, varying from 17.6% at any one time point to 29.2% over a lifetime[3]. A large proportion of the population is exposed to social, occupational, and physical health impairment, in addition to a higher mortality rate[2]. A poor work environment such as job strain, effort-reward imbalance, low job control, workplace bullying, job insecurity, overload, ambiguity, poor relationship with peers, and poor infrastructure are associated with a higher prevalence of common mental disorders among workers[5,6,7]
