Prevalence quantifies the proportion of individuals in a population who have a disease during a specific time period. Many studies have reported a high prevalence of various health problems, including mental health problems, among homeless people. The rate of bipolar disorder in this population may be difficult to measure due to diversity between studies in the definitions of homelessness and the diagnostic criteria used.

What is the evidence regarding prevalence of bipolar disorder in homeless populations?

Moderate quality evidence finds the prevalence of bipolar disorder in homeless people is around 11.4%. Rates were lowest in high-income countries (4%) and were similar across diagnostic instruments used.

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 for the prevalence of schizophrenia in homeless populations?

Moderate quality evidence suggests the overall prevalence rate of any psychotic disorder in homeless people is around 21%. Moderate to high quality evidence suggests the prevalence of schizophrenia spectrum disorders is around 12.4% in homeless populations in high-income countries. The prevalence rate of schizophrenia is higher in developing countries (22%).

Moderate quality evidence shows rates of schizophrenia in homeless populations varied across US cities, with rates higher in Los Angeles than in New York, which had higher rates than Philadelphia. Rates were generally higher in younger than older age-groups, higher in chronically homeless people, and higher in women than in men.

What is the evidence for homelessness?

Moderate to high quality evidence found the prevalence of schizophrenia spectrum disorders was around 12.4% in high-income countries and 22% in developing countries. The prevalence rate of any psychotic disorder in homeless people was around 21%. Rates of schizophrenia were higher in people who were homeless over the long term, and were generally higher in homeless women than in homeless men.
