Suicide is one of the leading causes of death. The current systematic review is done to know the trend of suicidal thoughts, suicidal ideation, and self-harm during COVID-19 pandemic.
The search was done by using PubMed, ScienceDirect, and Google Scholar databases. With the help of Mendeley portal, articles were retrieved on the basis of inclusion criteria like to know the risk factors, vulnerable group, complete article PDFs, prevention strategies, aims, results, and limitations. The shortlisted data from search was tabulated, and the PRISMA chart was framed based on the inclusion and exclusion criteria.
Sixteen studies that satisfied the inclusion criteria were organized and selected. The variables and global scenario were considered in databases. It has been noticed that trends of suicidal thoughts, suicidal ideation, and self-harm remains the same in some countries like Japan, whereas in some countries like Bangladesh and France, trends of suicides had increased during the pandemic period. The probable cause could be lockdown, social isolation, and stoppage of recreational activities.
The trends of suicidal ideation, suicidal thoughts, and self-harm are more in vulnerable categories like health care professionals, university students, elderly individuals, and psychiatrically ill patients. In health care professional, it is due to the increased risk of contagion and watching deaths closely. In university students, it is due to the lack of recreational activities and social isolation. Among elderly, it is due to thinking themselves as overburden. The increase in suicidality in psychiatric ill patient admitted during COVID-19 pandemic is due to unknown cause.
自杀是主要死因之一。进行本次系统评价是为了了解在新冠疫情期间自杀念头、自杀意念和自我伤害的趋势。
通过使用PubMed、ScienceDirect和谷歌学术数据库进行检索。借助Mendeley平台，根据纳入标准检索文章，如了解风险因素、弱势群体、完整的文章PDF、预防策略、目的、结果和局限性。将检索出的入围数据制成表格，并根据纳入和排除标准绘制PRISMA图表。
整理并挑选出16项符合纳入标准的研究。考虑了数据库中的变量和全球情况。已经注意到，在日本等一些国家，自杀念头、自杀意念和自我伤害的趋势保持不变，而在孟加拉国和法国等一些国家，疫情期间自杀趋势有所增加。可能的原因是封锁、社会隔离和娱乐活动的停止。
自杀意念、自杀念头和自我伤害的趋势在医护人员、大学生、老年人和精神病患者等弱势群体中更为明显。在医护人员中，这是由于感染风险增加和密切目睹死亡。在大学生中，这是由于缺乏娱乐活动和社会隔离。在老年人中，这是由于他们认为自己负担过重。新冠疫情期间收治的精神病患者自杀倾向增加的原因不明。
