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.
背景
新冠疫情对全球心理健康产生了影响，影响了自杀死亡率。本研究评估了2000年至2022年新冠疫情对巴西自杀死亡率的影响。
方法
利用死亡信息系统（MIS）的自杀事件数据进行时间序列事件研究。按每10万居民计算死亡率。采用Wilcoxon符号秩检验和Prais-Winsten回归评估疫情前和疫情期间的差异。进行了中断时间序列（ITS）分析。
结果
2000年至2022年期间，巴西有243,143例自杀病例。在疫情期间，每10万居民的月自杀死亡率中位数从0.4上升至0.6，且有每月上升0.78%的趋势。
局限性
由于这是一项生态学研究，无法得出个体层面的结论。二手数据和人口估计可能不准确。
结论
新冠疫情增加了巴西的自杀死亡率，凸显了制定更有效心理健康政策的必要性。
