Prevalence in humanitarians

What is prevalence of PTSD in humanitarians?

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?

Moderate quality evidence finds the overall prevalence of PTSD in humanitarians is between 6.2% and 42%. Rates were generally higher in humanitarian cohorts than in the general population exposed to the same disaster.
