That's according to a report by the Oregon Health Authority that analyzed data from the state's Violent Death Reporting System from 2008 to 2012.
The Oregonian reports that the suicides covered all age groups, including veterans of long-ended wars. The largest segment of suicide victims was men over the age of 55. For veterans under 45, the report says suicide is the leading cause of death.
Suicide victims often struggled with a variety of contributing issues, from mental health problems to alcohol abuse to relationship struggles, the report noted.
The highest rates of veteran suicide occurred outside the Portland area.
