Summary

Suicide has been a feature of the human species ever since the beginning of written history and even much earlier, often marking the peak of human suffering – both for the individual that died from it and those left questioning why it happened and how it could have been prevented. However, despite profuse investments in suicide prevention programs and striking advances in psychiatry in past decades, suicide mortality still represents the second most common cause of death in youth worldwide [1]. A recent estimate of the prevalence of past-year suicidal ideation (SI), planning, and attempts in adolescents reached 17% in low- and middle-income countries [2]. Though outnumbered by other causes of death in older age, suicide rates tend to increase with age [3], making it one of the key causes of death worldwide that could theoretically be prevented.
