Background: Without integration of the available information, appropriate suicide preventive actions can be hindered. Therefore, this study attempts to review the Bangladeshi COVID-19-related suicide studies for the first time.
Methods: For conducting a systematic review, the PRISMA guideline was adhered. Bangladeshi literatures concerning the COVID-19 pandemic related to either suicide case or suicidal behavior were identified within 1 to 10 April 2021, from the databases like PubMed, Scopus, PsycINFO, Web of Science, CINAHL, etc. Finally, a total of 9 literatures were included in this review.
Results: Four literatures were cross-sectional studies assessing the prevalence and risk factors of suicidal behavior, and the rest five were retrospective suicide studies concerned with either case study (n=3) or case-series study (n=2). The prevalence of suicidal ideation was identified to be ranging between 5% and 19.0%, whereas the rate increased over time of the pandemic inception. Significant risk factors concerning suicidal behavior included the factors related to (i) socio-demographic variables: female gender, being divorced or widows or widowers or single in marital status, having lower levels of education, being urban residence, belonging to higher socioeconomic class, being unemployed, and having no children, (ii) behavior and health-related variables: lack of physical exercise, cigarette smoking, alcohol consuming, abnormal sleep status, more exposure to social media, and suffering from the higher number of physical health problems; (iii) COVID-19 pandemic-related variables: lower knowledge of COVID-19, lack of preventive COVID-19 behaviors, higher levels of COVID-19 fear, living in highly COVID-19 infected area, higher economic loss due to the pandemic, and experiencing relatives or acquaintances’ death by the COVID-19; (iv) psychopathological variables: depression, anxiety, stress, insomnia, suicidal thought history, suicide attempt history, and family with a history of suicide.
Conclusion: Implementing cost-effective mental health strategies along with social and community awareness for increasing help-seeking behaviors of suicide risky individuals is highly suggested.

孟加拉国 COVID-19 大流行背景下的自杀和自杀行为：系统评价

背景：如果不整合可用信息，可能会阻碍适当的自杀预防措施。因此，本研究首次尝试回顾孟加拉国与 COVID-19 相关的自杀研究。
方法：为了进行系统评价，遵循 PRISMA 指南。在 2021 年 4 月 1 日至 10 日期间，从 PubMed、Scopus、PsycINFO、Web of Science、CINAHL 等数据库中确定了孟加拉关于 COVID-19 大流行与自杀病例或自杀行为相关的文献。最后，共有 9 篇文献被纳入本次审查。
结果：四篇文献是评估自杀行为的患病率和危险因素的横断面研究，其余五篇是回顾性自杀研究，涉及案例研究（n = 3）或案例系列研究（n = 2）。自杀意念的发生率被确定在 5% 到 19.0% 之间，而这一比例随着大流行开始的时间而增加。与自杀行为有关的重要风险因素包括与 (i) 社会人口变量相关的因素：女性、离婚或寡妇或鳏夫或单身婚姻状况、受教育程度较低、居住在城市、属于较高的社会经济阶层、失业，没有孩子，（ii）行为和健康相关变量：缺乏体育锻炼，吸烟，饮酒，睡眠状态异常，更多地接触社交媒体，并遭受更多的身体健康问题；(iii) 与 COVID-19 大流行相关的变量：对 COVID-19 的了解较少、缺乏预防性的 COVID-19 行为、对 COVID-19 的恐惧程度较高、生活在 COVID-19 高感染区、大流行造成的经济损失较高，以及亲人或熟人因 COVID-19 死亡；(iv) 精神病理学变量：抑郁、焦虑、压力、失眠、自杀念头史、自杀未遂史和有自杀史的家庭。因大流行导致更高的经济损失，以及因 COVID-19 导致亲属或熟人死亡；(iv) 精神病理学变量：抑郁、焦虑、压力、失眠、自杀念头史、自杀未遂史和有自杀史的家庭。因大流行导致更高的经济损失，以及因 COVID-19 导致亲属或熟人死亡；(iv) 精神病理学变量：抑郁、焦虑、压力、失眠、自杀念头史、自杀未遂史和有自杀史的家庭。
结论：强烈建议实施具有成本效益的心理健康策略以及社会和社区意识，以增加自杀风险个体的求助行为。
