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 people exposed to abuse and violence ?

Moderate to low quality finds the point prevalence of PTSD in people exposed to any violence is between 11.0% and 60.9% at one month post-exposure. By three months, point prevalence is between 5.8% and 30.4%, by six months it is between 1.9% and 23.9%, and by 12 months it is between 16.3% and 27.1%.

The prevalence of PTSD in people exposed to human trafficking is around 32%, and the prevalence of PTSD in children and adolescents in the welfare system is 4%. Not all of the child welfare sample were exposed to abuse or violence, so this prevalence rate is an estimate.

Moderate to high quality evidence finds the prevalence PTSD in children after an injury is 20.52%. Rates were highest in girls, in older children, and in children injured during a hurricane. The prevalence of PTSD in children exposed to earthquake is around 23.6%. Being older, having higher education, being trapped, experiencing fear, injury, or bereavement, and witnessing injury/death during the earthquakes were related to greater risk of PTSD.

What is the evidence for the prevalence of PTSD following disasters?

Moderate to low quality evidence found the mean prevalence of PTSD following public health disasters (SARS outbreaks) to be around 14%, after natural disasters (earthquakes, hurricanes) mean prevalence was around 18%, and after man-made disasters (war, terrorism) mean prevalence was around 24%.

There were vast differences in prevalence rates of PTSD across studies. The prevalence of PTSD in adults exposed to earthquakes was between 4.1% and 67.7% and between 2.5% and 60% for children exposed to earthquakes. Being female, having low education, low socio-economic status, prior trauma, being trapped, and experiencing fear, injury, or bereavement were all related to greatest risk of PTSD in adults exposed to earthquakes. In children exposed to earthquakes, being older, having higher education, being trapped, experiencing fear, injury or bereavement, and witnessing injury/death during the earthquake were all related to the greatest risk of PTSD.

After hurricanes, the prevalence of PTSD was between 9.0% and 36.7%. Following cyclones and tornadoes the prevalence was between 1.0% and 90.0%. After fires, the prevalence was between 9.0% and 36.7%. After floods the prevalence was between 2.05% and 37.0%. Following ship sinking the prevalence was between 50.0% and 89.5%. After the 9/11 attack the prevalence was between 2.3% and 35.0%. The prevalence of PTSD in children and adolescents after tsunamis was between 6.0% and 70.7%.

What is the evidence for the prevalence of PTSD in elderly people?

Moderate quality evidence finds the 12-month prevalence rate of PTSD in older adults (≥65 years) is 1.56%, and the lifetime prevalence rate of PTSD in older adults is 2.66%. Lifetime prevalence rates of PTSD are nearly twice as high in women than in men.

The prevalence rate of PTSD in older prisoners (≥50 years) is 6.2%. Prevalence of PTSD in older US veterans (≥65 years) is 8.4%. The prevalence of PTSD in older adults (≥65 years) after a fall is 27.5%, which represents a small, significant increase in risk of PTSD when compared to older people with no previous fall.

What is the evidence for the prevalence of PTSD in epidemic or pandemic survivors?

Moderate to high quality evidence finds the overall prevalence of PTSD within 12 months of an infectious disease pandemic is around 22.6%. Rates were highest in frontline healthcare workers, during COVID-19 (rather than during severe acute respiratory syndrome, Middle East respiratory syndrome, Ebola, or H1N1), and in individuals exposed to quarantine (home or hotel).

Moderate quality finds the rates of PTSD were higher in coronavirus patients with a history of physical illness, functional impairment, pain, and in those experiencing a lack of control.

One-year prevalence in male prisoners is 9.9%, and in female prisoners it is 26.1%. Lifetime prevalence in male prisoners is 17.8%, and in female prisoners it is 40.4%. These rates are significantly higher in females than males, and are also significantly higher in studies conducted in high-income countries when compared to low income countries.

Moderate quality evidence finds the point prevalence of PTSD in adolescent males in detention centres is 8.6%, and it is 18.2% in adolescent females in detention centres. Moderate to low quality evidence finds the point prevalence of PTSD older prisoners (>50 years) is 6.2% (males and females combined).

What is the evidence for the prevalence of PTSD?

Moderate quality evidence finds the mean prevalence of PTSD in doctors is 14.8%, with rates highest in doctors treating trauma patients (21.5%), and lowest in doctors practicing medicine in rural areas (4.4%). The mean prevalence of PTSD in ambulance personnel is 11%, with rates reducing over time from 20% in 1985 to 0.05% in 2017, perhaps due to improved mental health training and post-incident support processes in that profession over time. Moderate to low quality evidence finds the mean prevalence of PTSD in medical responders during a disaster is 20.5%.

Moderate to high quality evidence finds the mean prevalence of PTSD in healthcare workers during a coronavirus outbreak is around 18%. Rates were higher during the Middle East respiratory syndrome (MERS; 2017-2020) outbreak than during the severe acute respiratory syndrome (SARS; 2004-2009) or Coronavirus disease 2019 (COVID-19; 2020 only) outbreaks. Rates were higher when PTSD was measured during an outbreak rather than after an outbreak and were higher in cross-sectional than in cohort studies.

Moderate to low quality evidence finds the prevalence of PTSD in healthcare workers after exposure to workplace violence is between 5% and 32%.
