Military women are at the same risk of PTSD as men, study finds

As high-ranking military chiefs debate allowing women into the front lines of combat, researchers from the Department of Defense and Veterans Affairs are adding new research to the mix: Women warriors are at the same risk of post-traumatic stress disorder as men.

The finding, published in the latest issue of the Journal of Psychiatric Research, offers insight into the long-term mental health effects of military service for women — including experience with combat. The evidence pads the argument in favor of allowing women to join infantry and some elite units of the military, the subject of fierce debate.

The study looked at more than 2,300 pairs of men and woman deployed to Iraq or Afghanistan and matched based on a number of variables — such as combat exposure, age, race, military occupation, marital status and pay grade. The researchers followed the pairs for an average of seven years and found that 6.7 percent of women and 6.1 percent of men developed PTSD.

The researchers said the difference was not statistically significant and that there wasn’t a difference in severity for those who did develop the disorder.

Previous studies have been a bit of a mixed bag in terms of PTSD rates among military women, but some studies have reported that women are at higher risk of PTSD. That’s commonly been used as an argument against letting women fight alongside male peers on the front lines.

But those studies focus on military populations as a whole, regardless of the individuals’ previous cases of PTSD. Women in the general civilian population are also more likely to suffer interpersonal trauma — such as sexual assault — through people who they’re familiar with.

“We were able to adjust for a number of things that people were unable to adjust for in the past,” said Shira Maguen, an author of the study and a mental health director of the the San Francisco VA Medical Center. “This issue of exposure is extremely important. We’re looking at different types of exposure.”

In this study, researchers only looked at men and women who had no previous indications of PTSD, and found there’s no difference in newly developed cases of the disorder. That’s also why this study is reporting a lower PTSD rate among veterans than earlier estimates, which put the disorder at as high as 20 percent for returning Iraq and Afghanistan veterans.

Keeping track of the PTSD is important, as an estimated 2.7 million American veterans of the Iraq and Afghanistan wars are affected by it. The disorder is triggered by traumatic events, with symptoms including flashbacks, nightmares, bouts of anger and severe anxiety. For most people, the symptoms go away over time, but for others, they are a difficult hurdle in living a normal life.

While it can be treated with the use of antidepressant medications and psychotherapy, only half of veterans seek treatment — and of those, only half get “minimally adequate care,” according to a study by  the Rand Corp.

The study came out at a time of heightened interest in women’s future role in the military combat. In early 2013, then-Defense Secretary Leon Panetta rescinded the ban on women in combat, giving the different branches of the military until January 2016 to request exceptions to the new policy.
