Mental Health Impairment and Outpatient Mental Health Care of US Children and Adolescents

Importance Despite a federal declaration of a national child and adolescent mental health crisis in 2021, little is known about recent national trends in mental health impairment and outpatient mental health treatment of US children and adolescents. Objective To characterize trends in mental health impairment and outpatient mental health care among US children and adolescents from 2019 to 2021 across demographic groups and levels of impairment. Design, Setting, and Participants Survey study with a repeated cross-sectional analysis of mental health impairment and outpatient mental health care use among youth (ages 6-17 years) within the 2019 and 2021 Medical Expenditure Panel Surveys, nationally representative surveys of US households. Race and ethnicity were parent reported separately from 15 racial categories and 8 ethnic categories that were aggregated into Black, non-Hispanic; Hispanic; Other, non-Hispanic; and White, non-Hispanic. Exposure Time period from 2019 to 2021. Main Outcomes and Measures Age- and sex-adjusted differences between 2019 and 2021 in mental health impairment measured with the Columbia Impairment Scale (a score ≥16 indicates severe; 1-15, less severe; and 0, no impairment) and age-, sex-, and Columbia Impairment Scale strata–adjusted differences in the use of any outpatient mental health care in 2019 and 2021. Results The analysis involved 8331 participants, including 4031 girls and 4300 boys; among them, 1248 were Black and 3385 were White. The overall mean (SE) age was 11.6 (3.4) years. The percentage of children and adolescents with severe mental health impairment was 9.7% in 2019 and 9.4% in 2021 (adjusted difference, −0.3%; 95% CI, −1.9% to 1.2%). Between 2019 and 2021, there was also no significant difference in the percentage of children and adolescents with less severe impairment and no impairment. The overall annual percentages of children with any outpatient mental health care showed little change: 11.9% in 2019 and 13.0% in 2021 (adjusted difference, 1.3%; 95% CI, −0.4% to 3.0%); however, this masked widening differences by race. Outpatient mental health care decreased for Black youth from 9.2% in 2019 to 4.0% in 2021 (adjusted difference, −4.3%; 95% CI, −7.3% to −1.4%) and increased for White youth from 15.1% to 18.4% (adjusted difference, 3.0%; 95% CI, 0.0% to 6.0%). Conclusions and Relevance Between 2019 and 2021, there was little change in the overall percentage of US children and adolescents with severe mental health impairment. During this period, however, there was a significant increase in the gap separating outpatient mental health care of Black and White youth.
