Estimates from population-based studies indicate that older adults drink more frequently than younger age groups. Data from the 2010 Australian national household survey reported that daily drinking was evident in 13.3% of older adults aged 60–69 years and in 14.8% of older adults aged 70+ years. These findings are compared to daily drinking rates reported by 10.1% of adults aged 50–59 years and 7.5% in the 40–49 years age range (Australian Institute of Health and Welfare, 2011). The study of alcohol consumption in older adults is particularly important because of their increased sensitivity to alcohol-related harms. With age, the body's ability to process alcohol decreases as a result of physiological changes, such as decreases in body mass and higher levels of fatty tissue, leading to a higher blood alcohol concentration for a given dose compared with younger adults (National Institute on Alcohol Abuse and Alcoholism, 1998). This greater vulnerability to the effects of alcohol necessitates a stronger understanding of drinking practices in older adults.
