Racial-ethnic Differences in Reasons for Misuse of Prescription Medications Among US Adults

Abstract

Objectives: This study aims to investigate racial-ethnic differences in reasons for misuse of prescription medications among a nationally representative sample of US adults.

Methods: We analyzed data from the 2015-2019 National Surveys on Drug Use and Health. The study population includes US adults (18-49 years old) who reported misuse of 3 types of prescription drugs (stimulants [n = 6139], sedatives and tranquilizers [n = 5643], and pain relievers [n = 8780]) for 3 reasons: medical-only (eg, to help with pain), recreational-only (eg, to get high), or combined medical and recreational reasons. Multinomial logistic regressions assessed the association between reasons of misuse of prescription medications and self-identified race-ethnicity.

Results: Misuse of the 4 types of prescription medications was primarily motivated by medical reasons (63%-80%). Compared to non-Hispanic Whites, non-Hispanic Blacks (nHB), and Hispanics (H) were less likely to report misuse of pain relievers for combined (nHB: adjusted relative risk ratio [aRRR] = 0.6, 95% confidence interval [CI]: 0.4, 0.7; H; aRRR = 0.7, 95% CI: 0.5, 0.9) or recreational reasons (nHB: aRRR = 0.8, 95% CI: 0.6, 1.0; H; aRRR = 0.7, 95% CI: 0.6, 0.9) rather than medical-only reasons. The odds of misuse of sedatives and tranquilizers for recreational-only reasons as opposed to medical-only reasons were higher among nHB (aRRR = 1.9, 95% CI: 1.3, 2.7) and H (aRRR = 1.9, 95% CI: 1.4, 2.4) than among non-Hispanic Whites.

Conclusions: The increased misuse of prescription pain relievers for medical reasons among racial-ethnic minority groups demonstrates a continued need to investigate underlying structural factors driving these behaviors. The higher odds of sedative and tranquilizer misuse for recreational purposes among racial-ethnic minority groups warrant further investigation.
