Background
The COVID-19 pandemic has impacted global mental health, affecting mortality from suicide. This study evaluated the impact of COVID-19 on suicide mortality in Brazil from 2000 to 2022.

Methods
Study of temporal events with data of events by suicide of the Mortality Information System (MIS). Mortality were calculated per 100,000 inhabitants. Differences before and during the pandemic were evaluated with the Wilcoxon Signed-Rank Test and Prais-Winsten regression. Interrupted Temporal Series (ITS) analysis was performed.

Results
Between 2000 and 2022, there were 243,143 cases of suicide in Brazil. During the pandemic, the median monthly mortality increased from 0.4 to 0.6 per 100,000 inhabitants, with a trend of an increase of 0.78% per month.

Limitations
Because it is an ecological study, it is not possible to have individual conclusions. Secondary data and population estimates may be inaccurate.

Conclusions
The COVID-19 pandemic has increased suicide mortality in Brazil, highlighting the need for more effective mental health policies.
