Alcohol, tobacco, and nonmedical drug use disorders in U.S. Adults aged 65 years and older: data from the 2001-2002 National Epidemiologic Survey of Alcohol and Related Conditions.
OBJECTIVE
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.


METHODS
The 2001-2002 National Epidemiologic Survey on Alcohol and Related Conditions, a cross-sectional survey of a population-based sample.


METHODS
The United States.


METHODS
Eight thousand two hundred five adults aged 65 years and older.


METHODS
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.
