Prevalence in refugees
What is prevalence of schizophrenia in refugees? Prevalence quantifies the proportion of individuals in a population who have a disease during a specific time-period while incidence refers to the number of new cases of disease that develop in a population during a specific time-period while. In disorders of short duration incidence and prevalence rates may be similar, however with disorders of long duration such as with schizophrenia there can be variation between the two. What is the evidence regarding prevalence of schizophrenia in refugees? High quality evidence finds the overall prevalence of psychotic disorders, mostly schizophrenia spectrum, is 1.5% in…
Prevalence in refugees
What is prevalence of PTSD in refugees? 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…
Incidence in migrants
What is the incidence of bipolar disorder in migrants? The incidence of bipolar disorder refers to how many new cases 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. Differences in the incidence of a disorder can provide clues to its possible causes. The term “migrant” usually refers to first generation migrants – people with a foreign birth place, however some studies also include locally born offspring, or second generation migrants in their analyses. What is the evidence for incidence…
Migration
How is migrant status related to bipolar disorder? The term “migrant” usually refers to first generation migrants – people with a foreign birth place, and studies have assessed whether migration is related to risk of bipolar disorder. Any association observed between migrant status and increased risk of mental disorders has stimulated a great deal of explanatory hypotheses, including additional stress relating to migration and settling into a new country, and possible issues with discrimination. Other explanations include a tendency for at-risk individuals to migrate, and underlying genetic variances across cultures. What is the evidence for migrant status as a risk…
Incidence in refugees
What is incidence and how it is relevant to schizophrenia? Incidence refers to how many new cases 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. Incidence is usually reported as the number of new cases per 100,000 people per year. Alternatively some studies present the number of new cases that have accumulated over several years against a person-years denominator. This denominator is the sum of individual units of time that the persons in the population are at risk of…
Prevalence in migrants
What is prevalence of schizophrenia in migrants? 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 prevalence rates in migrant populations? Moderate quality…
Incidence in migrants
What is incidence of schizophrenia in migrant groups? 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 in…
Migration
How is migration related to schizophrenia? The term “migrant” usually refers to first generation migrants; people with a foreign birth place, however some studies also include their locally-born offspring, or second generation migrants. Any association found between migrant status and increased risk of schizophrenia has stimulated a great deal of research and explanatory hypotheses, including the stress relating to migration and settling into a new country, and possible issues with discrimination. Other explanations include a tendency for at-risk individuals to migrate, and differences in underlying genetic vulnerability across cultures.
