To add to the limited data on the prevalence, clinical characteristics, and treatment of bipolar disorder (BD) among immigrants.
Data were obtained from a large epidemiologic survey, the Canadian Community Health Survey-Mental Health and Well-Being (CCHS 1.2). Lifetime prevalence rates of BD were compared between immigrant and nonimmigrant respondents. Among BD subjects (n = 831), sociodemographic, clinical, and mental health treatment use variables were compared based on immigrant status. Logistic regression was used to determine the correlates of lifetime contact with a mental health professional and 12-month psychotropic medication use.

There were few sociodemographic or clinical differences, yet immigrants with BD were significantly less likely to report any lifetime contact with mental health professionals (OR = 0.25, 95% CI 0.13 to 0.50, P
