There were 176 suicides of victims ages 9-18 years old, with a mean age of 17.4 years. The overwhelming majority of the victims were older adolescents (15-19 years old). Sixty percent of the suicides were male; 96 percent were single. The most frequent means of suicide was hanging (55 percent). Possible reasons reported for the suicides were mainly psychiatric disorders, followed by troubles within the family. Only 6 percent of the victims were known to have made a prior suicide attempt. These findings are consistent with the literature in terms of the prevalence of male victims, the prevalence of victims in late adolescence, the use of hanging as the preferred method of death, and the prevalence of psychiatric disorders among victims. The authors advise that adolescent suicide prevention programs must emphasize early identification and appropriate treatment of an underlying psychopathology. Adolescents are at particular risk for suicide, so programs are needed to train parents, teachers, and physicians in recognizing depressive disorder among youth. A strong social support system is an essential component in reducing suicide risk. Access to firearms should also be restricted.
