Prevalence refers to how many people in the population as a whole have a disorder. It is a measure of the total number of cases of a disorder within a specific population during a specific time period, regardless of when the disorder began. This is different from incidence, which refers to how many new cases of a disorder occur during a given period of time. Option B refers to incidence, not prevalence. Option C refers to the gender distribution of a disorder, not prevalence. Option D refers to recovery from a disorder, not prevalence.
