Suicide is one of the important issues that has not been considered a focus of public health interventions in Bangladesh. Currently, there is no available national suicide data-keeping system, suicide research focusing on psychopathology, and integrated intervention or prevention programmes, which are urgent needs for Bangladesh. It has been found that suicide researchers collected data from injury death record reviews, autopsy record reviews, death registry reviews, news or media report analyses, and case reports. S.M.Y Arafat has authored the highest number of papers on suicide in Bangladesh according to the Scopus database from inception to date. The overall information in this chapter will help to detect unexplored areas of suicide in Bangladesh and show the direction of future research domains, which will be helpful to develop effective local suicide prevention policies, strategies, and interventions.
