On average, every day one active duty member of the military and 22 veterans commit suicide.

And from 2005 to 2009, Army suicide attempts and suicides rose sharply.

In an attempt to figure out how to focus early interventions, a team of researchers has pulled

together data from various Army databases to analyze nearly 10,000 attempted suicides of active

duty Army personnel.

The first major point they make is that enlisted soldiers, not officers, attempt suicides

at higher rates.

Enlisted soldiers represent about 83% of the army, but make up nearly 99%

of the suicide attempts. Narrowing in on the data, the researchers determined that females were

more than twice as likely as males to attempt suicide. Also at higher risk, soldiers who entered the

army at age 25 or older, and suicides were higher for those who'd never been deployed or those

who were home from deployment than for those who are currently deployed. Suicides were highest

in the first two years of service, particularly the first year, and among soldiers who attempted

suicide, more than half had received a mental health-related diagnosis in the previous month.

The study is in the journal JAMA psychiatry.

One limitation of the study, the researchers acknowledge, is that it only includes data from the
