Suicide risk in people with post-traumatic stress disorder: A cohort study of 3.1 million people in Sweden.

ABSTRACT:

Background

It is unclear whether post-traumatic stress disorder [PTSD] is associated with suicide risk in the general population, whether this differs by sex, or what the population impact of PTSD is for suicide.

Methods

We constructed a nationwide cohort of all people living in Sweden, born 1973-1997, followed from their 14th birthday (or immigration, if later) until suicide, other death, emigration or 31 December 2016. We used Cox proportional hazards regression to estimate hazard ratios [HR], and calculated the population impact of PTSD on suicide. We included sensitivity analyses to explore effects of outcome and exposure definitions, and to account for potential competing risks.

Results

Of 3,177,706 participants, 22,361 (0•7%) were diagnosed with PTSD, and 6,319
