Nationwide trends in diagnosed sedative, hypnotic or anxiolytic use disorders in adolescents and young adults enrolled in Medicaid: 2001-2019.

BACKGROUND AND AIM: Sedative, hypnotic or anxiolytic use disorders (SHA-UD) are defined by significant impairment or distress caused by recurrent sedative, hypnotic or anxiolytic use. This study aimed to measure trends in the prevalence of SHA-UD diagnoses in adolescent and young adult US Medicaid enrollees from 2001 to 2019.

DESIGN

Annual, cross-sectional study, 2001-2019.

SETTING

Medicaid Analytic eXtracts (MAX) and Transformed Medicaid Analytic Files (TAF) from 42 US states with complete data.

PARTICIPANTS/CASES: Adolescents (13-17 years) and young adults (18-29 years) with ≥10 months Medicaid enrollment in the calendar year; analytic sample contained 5.7 (2001) to 13.2 (2019) million persons per year.

MEASUREMENTS: Annual prevalence of SHA-UD in adolescent and young adult Medicaid enrollees [defined as an inpatient or outpatient ICD code (304.1x, 305.4x, F13.1x, F13.2x) in the calendar year] was stratified by sex, race/ethnicity, receipt of a benzodiazepine, z-hypnotic or barbiturate prescription, and selected mental health diagnoses. Absolute and relative percent-changes from 2001 vs. 2019 were summarized. Secondary analyses were restricted to states with more consistent data capture.

FINDINGS: The prevalence of SHA-UD diagnoses statistically significantly increased for adolescents (0.01% to 0.04%) and young adults (0.05% to 0.24%) from 2001 to 2019. Increasing trends were observed in sex and race/ethnicity subgroups, with greatest relative increases among Non-Hispanic Black (624%) and Hispanic (529%) young adults. The trend increased among those with and without a benzodiazepine, z-hypnotic or barbiturate prescription; i.e. young adults with (2001 = 0.39% to 2019 = 1.77%) and without (2001 = 0.03% to 2019 = 0.18%) a prescription. Most adolescents (76%) and young adults (91%) with a SHA-UD diagnosis in 2019 had a comorbid substance use disorder.

CONCLUSIONS

Sedative, hypnotic or anxiolytic use disorders (SHA-UD) diagnoses increased 3- to 5-fold between 2001 and 2019 for adolescent and young adult US Medicaid enrollees, with prevalence remaining low in adolescents. The increase over two decades may be attributed to changes in the availability, use and misuse of sedative, hypnotic and anxiolytic medications and to increased detection, awareness and diagnosing of SHA-UD.
