Gay soldiers who do not reveal their sexuality while in service are more likely to attempt suicide, a study has found.
Researchers at the University of Montana and other institutions found compared to their straight counterparts, lesbian, gay and bisexual soldiers in the closet are more likely to be depressed, have anxiety disorders and take drugs.
From 1981 to 2011, the US anti-gay policy Don't Ask, Don't Tell (DADT) said gay people should not serve openly in the military, but the effects are still affecting thousands of people.
