OBJECTIVES: To examine the prevalence, sociodemographic, and health-related correlates of substance use disorders, including alcohol, tobacco, and nonmedical drug use among adults aged 65 years and older. DESIGN: The 2001-2002 National Epidemiologic Survey on Alcohol and Related Conditions, a cross-sectional survey of a population-based sample. SETTING: The United States. PARTICIPANTS: Eight thousand two hundred five adults aged 65 years and older. MEASUREMENTS: Prevalence of lifetime and past 12-month Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, determined alcohol, tobacco, and nonmedical drug use disorders. RESULTS: Prevalence of any substance use disorder was 21.1% during the lifetime and 5.4% in the past 12 months. Lifetime and past 12-month alcohol use disorders were 16.1% and 1.5%; tobacco use disorders were 8.7% and 4.0%; and nonmedical drug use disorders were 0.6% and 0.2%, respectively. Younger age was associated with greater odds of any lifetime or past 12-month substance use disorders. Men and those who were divorced or separated had greater odds of both lifetime alcohol and tobacco use disorders. Very good or excellent self-rated health was associated with lower odds of lifetime and past 12-month tobacco use disorders. Younger age and being divorced or separated were associated with greater odds of lifetime nonmedical drug use disorder. CONCLUSIONS: More than one in five older adults ever had a substance use disorder, and more than 1 in 20 had a disorder in the past 12 months, primarily involving alcohol or tobacco. Older adults have increased comorbidities and use of medications, which can increase risks associated with substance use.
