CBS News first revealed that young veterans in their early 20's were killing themselves at an unusually high rate back in late 2007. Using never-before-seen 2004 and 2005 data, CBS News discovered that the rate of suicide among young veterans was an estimated two to four times higher than any other age group.
The new preliminary data released by the Department of Veterans Affairs shows the suicide rate went up 26 percent from 2005 to 2007. It's assumed that most of the veterans in this age group served in Iraq or Afghanistan.
If there is a bright spot in the data, it's that in 2007 veterans in the group who used VA health care were less likely to commit suicide than those who did not. That's a change from 2005.
The military in recent years has struggled as well with an increase in suicides, with the Army seeing a record number last year. While the military frequently releases such data, it has been more difficult to track suicide information on veterans once they've left active duty.
The VA calculated the numbers using Centers for Disease Control and Prevention numbers from 16 states. In 2005, the rate per 100,000 veterans among men ages 18-29 was 44.99, compared with 56.77 in 2007, the VA said. It did not release data for other population groups.
The VA and the military have sought to more aggressively tackle the problem in recent years with measures ranging from a suicide hot line to educational campaigns.
At a conference on Monday in Washington dedicated to addressing the issue, VA Secretary Eric Shinseki said his agency needs to do a better job understanding what led to each suicide. He said he'd also like to see more stringent protocol put into place at VA facilities about how to handle a potentially suicide veteran, similar to what's done with someone who's having a heart attack.
He noted that of the 30,000 suicides each year in America, about 20 percent are committed by veterans.
"Why do we know so much about suicides but still know so little about how to prevent them?" Shinseki said. "Simple question but we continue to be challenged."
