The aim is to analyze the trend of work-related mental disorder notifications in Brazil from 2006 to 2024.
Conducted an ecological time series study using data from the Notifiable Health Conditions Information System (SINAN).
Divided notifications into pre-pandemic (2006-2019), pandemic (2020-2022), and post-pandemic (2023-2024) periods.
Used simple linear regression to determine the annual growth rates in notifications.
27,389 work-related mental disorders reported: 12,862 pre-pandemic (average 918.7/year), 5,792 during pandemic (1,930.6/year), and 8,735 post-peak (4,367.5/year).
Linear models showed annual growth rates of β +169 cases/year (R² = 0.933) pre-pandemic, +611 cases/year (R² = 0.992) during pandemic, and +1,049 cases/year (R² ≈ 1.000) post-pandemic.
The annual average of reported cases nearly doubled during the pandemic and quadrupled post-pandemic compared to the baseline.
