Abstract

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.

COVID-19大流行对巴西自杀死亡率的影响：中断时间序列分析

背景：COVID-19大流行影响了全球心理健康，影响了自杀死亡率。本研究评估了2000年至2022年COVID-19对巴西自杀死亡率的影响。方法：利用死亡信息系统（MIS）的自杀事件数据对时间事件进行研究。死亡率按每10万居民计算。采用Wilcoxon sign - rank检验和Prais-Winsten回归评估大流行前和大流行期间的差异。进行中断时间序列（ITS）分析。结果：2000年至2022年间，巴西共有243143起自杀事件。在大流行期间，每月死亡率中位数从每10万居民0.4人增加到0.6人，每月增长趋势为0.78%。局限性：由于这是一项生态学研究，因此不可能得出个别结论。二手数据和人口估计可能不准确。结论：2019冠状病毒病大流行增加了巴西的自杀死亡率，凸显了制定更有效的精神卫生政策的必要性。
