WEDNESDAY, Jan. 25 (HealthDay News) -- U.S. military personnel and veterans are plagued by substance abuse, depression and suicide, three new studies indicate.
In one study, researchers surveyed nearly 600 veterans returning from war zone deployment in Iraq or Afghanistan, and found that they were at increased risk for mental health problems and alcohol and drug abuse.

The studies were published online Jan. 25 in the American Journal of Public Health and are scheduled to appear in the March supplement print issue of the journal.
In the second study, researchers found that major depression and substance use disorders have increased among active duty combat-exposed veterans. The finding comes from an analysis of data from 678,382 active personnel serving between 2001 and 2006.
Those who were deployed to Iraq or Afghanistan were more likely to be diagnosed with major depression or substance abuse than non-deployed personnel. Army and Marine Corps personnel were more likely to be diagnosed with the conditions than Navy and Air Force personnel.
"Our study provided valuable insight for the mental health readiness of the U.S. armed services and implications for potential, continued support of ongoing operations and their post-deployment health care needs," the researchers wrote in a journal news release.
