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. (Am J Geriatr Psychiatry 2011; 19:292–299)

Study Sample

The sample was taken from the 2001–2002 NESARC, a population-based survey sponsored by the NIAAA.27 NESARC included a representative sample of the civilian, noninstitutionalized adult population 18 years and older in the U.S. Face-to-face interviews were conducted with 43,093 respondents, and the overall response rate was 81%. Among respondents, 8,205 (19%) were aged 65 years and older. Blacks, Hispanics, and young adults aged 18–24 years were oversampled. Weighted data were adjusted to be

Sample Sociodemographic and Health-Related Characteristics

The sample was predominantly younger than 75 years, female, white, married or living with someone, and retired. The sample was quite evenly distributed among the three education categories. Most of the sample had annual family incomes of less than $70,000, and reported good or better health (Table 1).

Prevalence of Alcohol, Tobacco, and Nonmedical Drug Use Disorders

More than 20% of the sample had a substance use disorder during their lifetimes and ∼5% of older adults had a substance use disorder during the past 12 months (Table 1). Approximately 16% had a

DISCUSSION

More than 20% of persons aged 65 years and older in 2001–2002 reported having a substance use disorder during their lifetimes and most of them had an alcohol use disorder. Alcohol, tobacco, and nonmedical drug use disorders were more likely in those who were younger, male, or divorced or separated. More than 5% reported having any substance use disorder in the past 12 months, and most of them had a tobacco use disorder. Less than 1% reported having a disorder involving nonmedical use of drugs.

      Some studies have used large national surveys to extrapolate possible risk factors for the older population. In a study of 8205 adults older than 65 years, Lin et al15 found that being 65 to 74 years old (compared with ≥75 years), white (compared with Asian/Pacific Islander), divorced/widowed, and male were associated with increased risks of lifetime AUD, whereas increased odds of having AUD in the past year were associated with being male and aged 65 to 74 years. Financial strain also places older adults, especially older women, at higher risk for heavy drinking.16

      Citation Excerpt :

      Efforts to understand the attitudes regarding coping behaviors and how to change unhealthy behaviors may reduce substance-use coping. We found no association between frequent alcohol-use coping and self-rated health, consistent with previous findings (Lin et al., 2011). Participants may have discontinued drinking as their health deteriorated, or turned to prescription/other drugs to cope with stress.
