This study describes trends of method-specific suicide mortalities in Norway
Changes in specific suicide methods have been identified in Norway from 1969 through 2012 in order to enhance our understanding of long-term trends of suicide as a basis for strategies and programs for suicide prevention.
Researchers at the National Centre for Suicide Research and Prevention (NSSF) have investigated different time trends for different suicide methods in Norway, demonstrating significant reductions in suicide by firearms, drowning, and poisoning after the peak in the suicide rate in the late 1980s. Suicide by means of hanging continuously increased emerging as an important public health concern in both sexes.
