Young men who have served in the British Armed Forces are up to three times more likely to take their own lives than their civilian counterparts, research published tomorrow (March 3) has found.
Researchers at The University of Manchester's Centre for Suicide Prevention linked UK military discharge data between 1996 and 2005 with details of suicides collected by the National Confidential Inquiry into Suicides and Homicides.
The study, published in the journal PLoS Medicine, revealed that ex-servicemen under 24 years old were at greatest risk of suicide, with those in lower ranks and shorter military careers proving most vulnerable.
The report's authors, Professor Nav Kapur and colleagues, were unable to prove why younger ex-military personnel had higher rates of suicide than men of the same age in the general population but suggest three possibilities.
"One explanation for the higher suicide risk among young ex-military personnel is that those entering military service at a young age are already vulnerable to suicide, which would explain why those serving for a relatively short period of time before being discharged were most likely to take their own lives," said Kapur, lead author and professor of psychiatry and population health at Manchester University.
"A second explanation is the difficulty a minority of individuals experience making the transition to civilian life.
"However, a third possibility that we could not explore in this study is that exposure to adverse experiences during military service or active deployment played a role in the two to three-fold increase in suicide among young veterans, although many of those most at risk had not completed basic training and therefore had not deployed overseas."
The study, funded by the Veterans Policy Unit in the UK Ministry of Defence, also found that the suicide risk was highest among young men leaving the Armed Forces within the first two years of discharge.
