ABSTRACT
OBJECTIVE: To characterize the distribution, data completeness, and temporal trends of notifications of Work-Related Mental Disorders (WRMD) in Brazil from 2007 to 2023.
METHODS: Cross-sectional and time-series study analyzing 22,378 notifications recorded in the Notifiable Diseases Information System (SINAN). Notifications were characterized according to demographic and clinical variables. Temporal trends were evaluated using the Joinpoint Regression Mode.
RESULTS: WRMD notifications increased from 0.13 per 100,000 employed working-age individuals in 2007 to 3.51 in 2023, with an average annual percent change of 18.24%, and peaks in 2009, 2017, and 2021. Most notifications involved women (64.86%), predominantly aged 35-49 years (49.27%). The Southeast and Northeast accounted for most cases, and anxiety and mood disorders were the most frequent diagnoses. Data completeness was excellent for sex and age group, fair for race/skin color and education, and insufficient for clinical variables related to substance use Temporary disability was reported in 56.38% of cases.
CONCLUSIONS: WRMD notifications increased substantially over the study period, particularly after 2021. Notifications predominated among women and workers aged 35-49 years, were concentrated in the Southeast and Northeast, and most frequently involved anxiety, stress-related, and somatoform disorders and mood disorders, with temporary disability reported in over half of cases.
