Determination of the prevalence of suicidal behaviors (thoughts, plans, and attempts) would help to comprehend the burden and chances of death by suicide. However, no previous meta-analysis was noted measuring the rates of different suicidal behaviors in Bangladesh. Therefore, we aimed to determine the prevalence of suicidal behavior in the country.
We registered the protocol in PROSPERO (CRD42024613969) and followed PRISMA 2020 guidelines. We searched PubMed and Scopus and conducted meta-analyses to pool the lifetime, 1-year, and point prevalence estimates for suicidal thoughts, plans, and attempts.
Our search included 34 studies with 27,992 responses between 2015 and 2024. Half of the studies were conducted among students. The pooled prevalence of suicidal thoughts was 24.2% (95% CI: 15.7%-35.3%) during the lifetime (15 studies, 12,710 subjects), 15% (95% CI: 10.7%-20.5%) during a year (20 studies, 15,020 subjects), and 6.7% (95% CI: 3.2%-13.8%) during a month (11 studies, 7047 subjects). Statistical heterogeneity ranged from 96.6% to 99.3%. The pooled prevalence of suicide plan was 5.6% (95% CI: 2.4%-12.8%) during the lifetime (7 studies, 5772 subjects), and 5.2% (95% CI: 3.1%-8.8%) during a year (5 studies). Statistical heterogeneity ranged from 82.1% to 97.9%. The pooled prevalence of suicide attempt was 7% (95% CI: 4.3%-11.1%) during the lifetime (15 studies, 11,699 subjects), and 3.9% (95% CI: 2.8%-5.3%) during a year (7 studies, 8107 subjects). Statistical heterogeneity ranged from 88.1% to 95.4%.
The rates of suicidal behavior are high in Bangladesh, as about one in four persons has thoughts and about one in fourteen persons has attempted during their lifetime. Attention from multiple stakeholders is warranted to ensure preventive measures in Bangladesh.
确定自杀行为（想法、计划和企图）的患病率有助于理解自杀死亡的负担和风险。然而，此前没有荟萃分析对孟加拉国不同自杀行为的发生率进行测量。因此，我们旨在确定该国自杀行为的患病率。
我们在国际系统评价前瞻性注册库（注册号：CRD42024613969）登记了研究方案，并遵循PRISMA 2020指南。我们检索了PubMed和Scopus数据库，并进行荟萃分析，以汇总自杀想法、计划和企图的终生患病率、1年患病率和时点患病率估计值。
我们的检索纳入了2015年至2024年间的34项研究，共27992份应答。其中一半的研究是在学生中开展的。自杀想法的汇总终生患病率为24.2%（95%置信区间：15.7%-35.3%）（15项研究，12710名受试者），1年患病率为15%（95%置信区间：10.7%-20.5%）（20项研究，15020名受试者），1个月患病率为6.7%（95%置信区间：3.2%-13.8%）（11项研究，7047名受试者）。统计异质性范围为96.6%至99.3%。自杀计划的汇总终生患病率为5.6%（95%置信区间：2.4%-12.8%）（7项研究，5772名受试者），1年患病率为5.2%（95%置信区间：3.1%-8.8%）（5项研究）。统计异质性范围为82.1%至97.9%。自杀企图的汇总终生患病率为7%（95%置信区间：4.3%-11.1%）（15项研究，11699名受试者），1年患病率为3.9%（95%置信区间：2.8%-5.3%）（7项研究，8107名受试者）。统计异质性范围为88.1%至95.4%。
孟加拉国的自杀行为发生率很高，约四分之一的人有过自杀想法，约十四分之一的人有过自杀企图。需要多个利益相关方予以关注，以确保在孟加拉国采取预防措施。
