Ethnicity

How is ethnicity related to risk for bipolar disorder?

Some ethnic groups may show greater or less risk for bipolar disorder than others. Incidence refers to how many new cases there are per population in a specified time period, while prevalence refers to how many existing cases there are at a particular point in time. Differences in the incidence and prevalence across various ethnic groups can provide clues to possible causes of bipolar disorder.

What is the evidence for ethnicity and risk for bipolar disorder?

Moderate quality evidence finds a medium-sized increased risk of affective psychosis (including bipolar disorder) in Black African and Black Caribbean ethnic groups living in England. There were also small increases in South Asian and other White groups (Irish, Eastern European).

Moderate to low quality evidence finds a small increased risk of bipolar disorder in people living in the US who have a Caucasian mother, with no association with having an African American mother or a mother from another ethnic background.
