Work-Related Illnesses and Work Disability in Brazil: A Scoping Review of the Epidemiological Profile and Determinants of Sick Leave and Occupational Accidents.

Background

This scoping review maps and synthesizes the scientific evidence on the epidemiological profile and determinants of sick leave and work-related accidents in Brazil, with an emphasis on studies using data from the Brazilian Federal Medical Expert Service of the Ministry of Social Security.

Methods

Following the PRISMA-ScR guidelines and the JBI Manual for Evidence Synthesis, eight databases (SciELO, PubMed/MEDLINE, Scopus, Web of Science, LILACS, CINAHL, PsycINFO, Embase) were searched for quantitative observational studies published between 2000 and 2025. Out of the 218 studies identified, 18 met the eligibility criteria.

Results

Cross-sectional designs (66.7%) and ecological/time-series designs (22.2%) predominated. The findings identified musculoskeletal disorders as the leading cause of work absence; mental disorders were the third leading cause, exhibiting an upward trend; and a significant influence of institutional factors, especially the Social Security Technical Epidemiological Nexus, on the observed patterns. Determinants operate at the individual, occupational/organizational, and institutional levels.

Conclusions

Empirical research on work disability in Brazil remains fragmented, providing limited capacity for causal inference. The findings support five priority areas: sectoral risk management, workplace mental health, territorial strategies for musculoskeletal disorders, sick leave trajectory policies, and data governance, all of which necessitate longitudinal and quasi-experimental studies to evaluate interventions and the impact of institutional changes.
