Drug and alcohol use disorders among adults with select disabilities: The national survey on drug use and health

Abstract

BackgroundDeaths caused by drugs and alcohol have reached high levels in the US, and prior research shows a consistent association between disability status and substance misuse. ObjectiveUsing national data, this study quantifies the association between disability status and drug and alcohol use disorders among US adults. MethodsThe most recent pre-pandemic years (2018–2019) of the cross-sectional National Survey on Drug Use and Health (n = 83,439) were used to examine how the presence of any disability, and specific disabilities, were associated with past year drug and alcohol use disorders. Logistic regression was used to estimate adjusted odds ratios (aORs) controlling for potential sociodemographic confounders. ResultsAdults with any disability had increased odds of drug (aOR = 2.7; 95% CI = 2.5–3.0), and alcohol use disorder (aOR = 1.8; 95% CI = 1.6–2.0), compared to adults without disability. Examining specific types of disabilities, adults with cognitive limitations only had increased odds of drug (aOR = 3.1; 95% CI = 2.6–3.6), and alcohol use disorders (aOR = 2.2; 95% CI = 1.9–2.5), compared to adults without disability. Smaller associations were observed between vision and complex activity limitations and drug use disorder. Adults with two or more types of limitations had increased odds of drug (aOR = 3.7; 95% CI = 3.3–4.3), and alcohol use disorders (aOR = 2.3; 95% CI = 2.0–2.6). ConclusionsThe presence of disability, especially cognitive limitation only, or two or more types of limitations, is associated with elevated odds of drug and alcohol use disorder among US adults. Additional research should examine the temporal relationship between and mechanisms linking disability and substance misuse.
