The Epidemiology of Suicide in Young Men in Greenland: A Systematic Review.

Suicide is the leading cause of death among young men aged 15⁻29 in Greenland, but few epidemiological studies have described this problem. We aimed to summarise descriptive epidemiological studies of suicide in young men in Greenland compared with other demographic groups in Denmark and Greenland to inform future suicide prevention strategy. We searched PubMed, PsycINFO, and Embase using an agreed search strategy to identify English-language papers describing suicide epidemiology in Greenlandic men aged 15⁻29. We followed PRISMA guidelines in screening and appraising eligible publications. Eight articles fulfilled inclusion criteria of 64 meeting search criteria. Findings covering 1970⁻2011 supported a dramatic rise in suicide rates in Greenlandic men aged 15⁻24 from 1976, who remained the highest-ranking demographic group over 1976⁻2011 compared with men and women of all age groups in Denmark and Greenland. Highest rates recorded were almost 600 per 100,000 per year in men aged approximately 20⁻23 over 1977⁻1986. No studies described suicide epidemiology after 2011, and no studies described risk factors for suicide in young men. Given the very high suicide rates recorded for young men over 1976⁻2011, such studies will be essential for informing the development and evaluation of appropriate preventive interventions.
