OBJECTIVES: To examine the prevalence and sociodemographic and health-related correlates of substance use, including alcohol, tobacco, and nonmedical drug use, in adults aged 65 and older.
DESIGN: Cross-sectional, retrospective survey of a population-based sample, the 2001/02 National Epidemiologic Survey on Alcohol and Related Conditions.
SETTING: United States.
PARTICIPANTS: Eight thousand two hundred five U.S. adults aged 65 and older.
MEASUREMENTS: Prevalence of lifetime and previous-12-month alcohol, tobacco, and nonmedical drug use and associations between substance use and sociodemographic and health-related factors.
RESULTS: Almost 80% of older adults had used any of the three substances over their lifetimes, and more than 50% reported such use over the previous 12 months. Alcohol was the most commonly used substance over the lifetime (74%) and in the previous 12 months (45%), followed by tobacco (52% lifetime; 14% previous 12 months); far fewer reported nonmedical use of drugs (5% lifetime; 1% previous 12 months). In general, being younger, male, and divorced or separated were factors consistently associated with use of any of the three substances.
CONCLUSION: Most older adults had used substances over their lifetimes and in the previous 12 months. Alcohol is the substance of choice for this age group, followed by tobacco; few report nonmedical drug use.
