Prevalence in males vs. females
What is prevalence? Prevalence represents the overall proportion of individuals in a population who have PTSD. 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 in a population who have the disorder at a given point in time (e.g., at one-month post-trauma), while period prevalence is the proportion of individuals in a population who have the disorder over specific time periods (e.g., one to two months post-trauma). Lifetime prevalence is the proportion of individuals in a population who have ever had the disorder and…
Incidence in males vs. females
What is incidence? The incidence of PTSD refers to how many new cases there are per population in a specified time-period after exposure to a specific event. It is different from prevalence, which represents how many overall cases exist. This topic presents the evidence on incidence rates in males compared to females. Please also see the topics on prevalence rates in males vs. females and the sex differences in risk of PTSD. What is the evidence for differences in incidence rates between males and females? Moderate quality evidence found the incidence of PTSD in children and adolescents was higher in…
Sex
How does female sex increase risk for PTSD? Personal characteristics, including gender, can influence one’s degree of risk for developing PTSD. How such personal characteristics may affect the development of PTSD would be influenced by other personal characteristics as well as differences in the trauma experience itself. What is the evidence for effects of sex on risk for PTSD? Overall, the risk of PTSD following exposure to any trauma was higher for females than for males. This has been observed in both adults and children. The quality of this evidence is generally moderate to high. For children and adolescents, there…
Sex differences
How are differences between the sexes relevant to people with schizophrenia? Sex differences have been reported in schizophrenia, including differences between sexes in the age of illness onset, in functioning, in symptom profile, and in the course of illness. This summary table assesses differences in the rates of schizophrenia between males and females as differences in incidence (number of new cases in the population at risk over a specified period of time) and prevalence (proportion of individuals who have the disorder in the population at risk at a specified time point or over a specified time period). Any sex differences…
Prevalence in males vs. females
What is prevalence of schizophrenia in males vs. females? Prevalence measures the proportion of individuals who have a disorder at a particular point in time (point prevalence) or during a specified period (annual prevalence, lifetime prevalence) and this may vary across regions. It is distinct from incidence, which refers to how many new cases there are per population in a specified time period. Lifetime prevalence is the number of individuals in a population that at some point in their life have experienced schizophrenia compared to the total number of individuals. What is the evidence regarding sex differences in prevalence rates…
Incidence in males vs. females
What is incidence of schizophrenia in males vs. females? Incidence refers to how many new cases of schizophrenia there are per population in a specified time period. It is different from prevalence, which refers to how many existing cases there are at a particular point in time, or over a lifetime. Incidence is usually reported as the number of new cases per 100,000 people per year, but this can vary. Differences in the incidence of a disorder can provide clues to its possible causes. For example, a population register with information gained from consensus data helps to identify all adults…
