PurposeDespite long-term emphasis on the medical home for children, little research focuses on adolescents. This study examines adolescent past-year attainment of medical home, its components, and subgroup differences among demographic and mental/physical health condition categories. MethodsUtilizing the 2020–21 National Survey of Children's Health (NSCH), ages 10–17 (N = 42,930), we determined medical home attainment and its 5 components and subgroup differences utilizing multivariable logistic regression: sex; race/ethnicity; income; caregiver education; insurance; language spoken at home; region; and health conditions: physical, mental, both, or none. ResultsForty-five percent had a medical home with lower rates among those who were as follows: not White non-Hispanic; lower income; uninsured; in non-English-speaking households; adolescents whose caregivers lacked a college degree; and adolescents with mental health conditions (p range = .01–<.0001). Differences for medical home components were similar. DiscussionGiven low medical home rates, ongoing differences and high mental illness rates, efforts are needed to improve adolescent medical home access.
