Prevalence in soldiers and veterans

What is prevalence of PTSD in soldiers and veterans?

Prevalence represents the overall proportion of individuals in a population who have the disorder of interest. It is different from incidence, which represents only the new cases that have developed over a particular time period. Point prevalence is the proportion of individuals who have the disorder at a given point in time. Period prevalence is the proportion of individuals who have the disorder over specific time periods. Lifetime prevalence is the proportion of individuals who have ever had the disorder. Lifetime morbid risk also includes those who had the disorder but were deceased at the time of the survey.

What is the evidence for the prevalence of PTSD in soldiers and veterans?

After military deployment to Iraq or Afghanistan, moderate quality evidence found the overall prevalence of PTSD was 23%. Rates were higher in Iraq-deployed personnel (12.9%) than in Afghanistan-deployed personnel (7.1%). They were higher in combat deployed personnel (12.4%) than in support personnel (4.9%). Rates were higher in army (13.2%) and marine (10.4%) personnel than in navy (7.3%) or air force (2.6%) personnel. They were higher in reserve or National Guard personnel (14.5%) than in active-duty personnel (11.4%).

The overall prevalence of PTSD in US army reserve members was 9.8%, and in US active service members, it was 8.9%. The prevalence of PTSD in peacekeepers between one month before and 6.6 years after deployment was around 5.3%. Prevalence of PTSD in UK service personnel ranged from 2.5% mid-deployment to 4.3% by over 2 years post-deployment.

Prevalence of PTSD was higher in military samples with a traumatic brain injury than in military samples without a traumatic brain injury (36.8% vs. 10.8%). The prevalence of PTSD in ex-military personnel with any physical impairment was between 2% and 59%.

The prevalence of PTSD in older US veterans (>65 years) was around 8.4%, and the prevalence of PTSD in US veterans involved in the justice system was between 4% and 39%.
