Estimated Prevalence of Psychiatric Comorbidities in U.S. Adolescents With Depression by Race/Ethnicity, 2011-2012.

PURPOSE

Comorbid psychiatric conditions in adolescents with depression are a public health concern. However, little is known about the prevalence of comorbidities in separate racial/ethnic groups. This study estimated the national prevalence of comorbidities for black, Hispanic, and white adolescents separately, and compared the prevalence of comorbidities between adolescents with and without depression.

METHODS

This secondary analysis used data from the 2011-2012 National Survey of Children's Health, a nationally representative, cross-sectional survey of U.S. youth. We restricted the sample to 12-17 year olds, and obtained unweighted and weighted descriptive statistics. Using weighted probit regression models, we examined differences in prevalence of comorbidities by adolescents with and without depression for each racial/ethnic group.

RESULTS

For black, Hispanic, and white adolescents with depression, the prevalence of comorbidities ranged from 8% to 61% and varied by race/ethnicity (e.g., depression and anxiety were comorbid for 47% of black, 54% of Hispanic, and 59% of white adolescents). For all racial/ethnic groups, adolescents with depression had a higher prevalence of attention deficit hyperactivity disorder than adolescents without depression. However, only black and Hispanic adolescents with depression had a significantly higher prevalence of anxiety and behavior problems than their counterparts without depression. In each racial/ethnic group, the prevalence of autism spectrum disorder did not differ between adolescents with and without depression.

CONCLUSIONS

This study detected important differences in the prevalence of comorbid psychiatric conditions by race/ethnicity. Findings highlight the need for targeted interventions for black and Hispanic adolescents with depression that concurrently treat anxiety and behavior problems.
