Alcohol Consumption by Aging Adults in the United States: Health Benefits and DetrimentsJournal of the American Dietetic Association VColume 108, Issue 10, Pages 1668-1676 (October 2008)
The most rapidly growing segment of the US population is that of older adults (≥65 years). Trends of aging adults (those aged ≥50 years) show that fewer women than men consume alcohol, women consume less alcohol than men, and total alcohol intake decreases after retirement.
A U- or J-shaped relationship between alcohol intake and mortality exists among middle-aged (age 45 to 65 years) and older adults. Thus, alcohol can be considered either a tonic or a toxin in dose-dependent fashion.
Active areas of research regarding the possible benefits of moderate alcohol consumption among aging individuals include oxidative stress, dementia, psychosocial functioning, dietary contributions, and disease prevention.
Yet, due to the rising absolute number of older adults, there may be a silent epidemic of alcohol abuse in this group.
Dietary effects of moderate and excessive alcohol consumption are reviewed along with mechanisms by which alcohol or phytochemicals modify physiology, mortality, and disease burden. Alcohol pharmacokinetics is considered alongside age-related sensitivities to alcohol, drug interactions, and disease-related physiological changes. International guidelines for alcohol consumption are reviewed and reveal that many nations lack guidelines specific to older adults.
A review of national guidelines for alcohol consumption specific to older adults (eg, those offered by the National Institute on Alcohol Abuse) suggests that they may be too restrictive, given the current literature. There is need for greater quantification and qualification of per capita consumption, consumption patterns (quantity, frequency, and stratified combinations), and types of alcohol consumed by older adults in the United States.
