Reuters – More than one-third of U.S. Army soldiers who attempt suicide don’t have a history of mental health problems, a recent study suggests. Attempted suicides have become more common among enlisted soldiers since the start of the wars in Afghanistan and Iraq, researchers note in JAMA Psychiatry. While a history of mental illness has long been linked to an increased risk of suicide among military service members and civilians alike, less is known about the risk among soldiers who haven’t been diagnosed with psychiatric disorders.
