Prevalence in indigenous people

What is prevalence of PTSD in indigenous people?

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?

High quality evidence finds the 12-month to lifetime prevalence of PTSD in American indigenous people is 7.66%, which is 1.47 times higher than in the general population.

Moderate quality evidence finds the current prevalence of PTSD in incarcerated indigenous females is 40.7% and is 14.2% in incarcerated indigenous males. The one-year prevalence rates range from 32.3% to 49.2% for incarcerated indigenous females and 12.1% to 19.5% for incarcerated indigenous males. The lifetime prevalence rate of PTSD in indigenous people living in the community is 55.2%.

No systematic reviews were identified or met inclusion criteria that assessed prevelance rates of PTSD in other indigenous groups.
