Use of psychotropic drugs by population in an area affected by the tailings dam rupture: Brumadinho Health Project.

Objective: To describe the consumption of psychotropic drugs in the adult population residing in Brumadinho, Minas Gerais, after the Vale dam collapse, which occurred in 2019.
Methods: This is a cross-sectional study, part of the Brumadinho Health Project, developed in 2021, with a representative population-based sample of adults (18 years and over) residing in Brumadinho. A total of 2,805 adults with information on self-reported use of psychotropic drugs (antidepressants and anxiolytics-hypnotics/sedatives) in the last 15 days were included in the analysis. The prevalence of psychotropic drug use was estimated, and the most used psychotropic drugs were identified. Pearson's chi-square test (with Rao-Scott correction) was used to test associations between exposures and use of psychotropic drugs, considering a significance level of p<0.05.
Results: The use of antidepressants (14.2%) was more common than the use of anxiolytics or hypnotics/sedatives (5.2%), with sertraline and fluoxetine being the most used antidepressants. The use of anxiolytics and hypnotics/sedatives was higher among residents who lived in the area directly affected by the dam's mud, and the use of any psychotropic drug was higher among those who lost a relative/friend in the disaster and assessed that their health worsened after the disaster, and among women.
Conclusion: The results of the study corroborate what was observed in other populations exposed to similar tragedies, regarding the pattern of associations and the of use of psychotropic drugs.
