Gun availability and gun control in suicide prevention
Suicide by firearm is the most lethal method of suicide and is executed much more frequently by men than by women. In comparison with other suicide methods, pre-existing psychiatric conditions are found less often and medical comorbidities more often. Suicide by firearm is carried out impulsively, frequently following a relationship crisis. Firearm suicide is mainly found in high- and middle-income countries. There is a close correlation between the frequency of firearm ownership and the frequency of this suicide method. People living in households with a gun generally seem to be at a higher risk of suicide. Several changes of legislation that lead to a decreased availability of guns have proven to be effective. However, legislation changes regarding firearms often lead to resistance by gun lobbies. Which intervention can be successfully implemented, mostly depends on country-specific circumstances.
