Alcohol use disorder and treatment receipt among individuals aged 50 years and older: Other substance use and psychiatric correlates.

Objective: Alcohol use disorder (AUD) is increasing among U.S. individuals aged 50+. We examined associations of past-year AUD with other substance use and any mental illness (AMI) and associations of past-year AUD treatment receipt with other substance use, AMI, and mental health treatment receipt among those with AUD.

Methods: Data came from the 2015-2018 National Survey on Drug Use and Health (N = 35,229). We used multivariable logistic regression analysis to examine the research questions.

Results: In the 50+ age group, 58.7% of women and 66.9% of men reported past-year alcohol use and 2.0% of women and 4.9% of men had AUD. Those with any alcohol use problem (binge drinking, heavy drinking, or AUD) had higher odds of other substance use or use disorders; however, AMI was associated with higher odds of AUD only (AOR = 2.54, 95% CI = 2.15-3.00, AOR = 2.63, 95% CI = 1.98-3.50, and AOR = 3.13, 95% CI = 2.19-4.48, respectively, for mild, moderate, and serious mental illness). Only 7.9% of those with AUD received any alcohol treatment. AMI and mental health treatment were associated with higher odds of alcohol treatment receipt (AOR = 5.18, 95% CI = 2.13-12.55, AOR = 4.14, 95% CI = 1.51-11.30, and AOR = 2.91, 95% CI = 1.41-6.00, respectively, for moderate mental illness, serious mental illness, and mental health treatment receipt).

Conclusion: The findings show that fewer than one in 10 older adults with AUD received any alcohol treatment and suggest that individuals need education on alcohol harms and assistance in accessing alcohol treatment. Combined mental health and alcohol treatment at a single location may improve access and use.
