Global trends of suicidal thought, suicidal ideation, and self-harm during COVID-19 pandemic: a systematic review

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.
