Associations between comorbid health conditions and the use of mental health services among adults with bipolar disorder.

Using a nationally representative sample, this study examined to what extent the number of comorbid health conditions was associated with various mental health service utilization among people with bipolar disorder. The results of logistic regression models indicate that a greater number of comorbid medical conditions were associated with higher odds of using specialty mental health service, while they were not associated with utilization of services provided by general health care providers. The type of bipolar disorder, functional impairment, and marital status were found to be associated with the use of a specialty service, while ethnicity was the only covariate significantly related to general health care use.
