The percentage of suicides ("almost 1 in 5") "documenting traumatic brain injury" that occurred among decedents "with a history of military service," according to a recent article published online ahead of print in the American Journal of Preventive Medicine -- Reported History of Traumatic Brain Injury Among Suicide Decedents: National Violent Death Reporting System, 2003–2017
From 2003 to 2017, a total of 203,157 suicide decedents were identified, and 993 had a documented traumatic brain injury before suicide. Among those with a documented traumatic brain injury, a higher percentage were White non-Hispanic. Firearm injuries were the most common method of suicide for both groups. Poisoning was more common among decedents with a previous traumatic brain injury than among those without. Male individuals, those who were single, and those who served in the military were 1.4 times more likely to have a documented traumatic brain injury history before the suicide. Almost 1 in 5 suicides (18.9%) documenting traumatic brain injury occurred among individuals with a history of military service.
