Background
The majority of US older adults consume alcoholic beverages. The older population is projected to almost double by 2050. Substantially more drinkers are likely.
Purpose
To describe gender-specific trends (1997–2014) in prevalence of drinking status (lifetime abstention, former drinking, current drinking [including average volume], and binge drinking) among US adults ages 60+ by age group and birth cohort.
Methods
In the 1997–2014 National Health Interview Surveys 65,303 respondents ages 60+ (31,803 men, 33,500 women) were current drinkers; 6,570 men and 1,737 women were binge drinkers. Prevalence estimates and standard errors were computed by age group (60+, 60–64, 65–69, 70–74, 75–79, 80+) and birth cohort (<1925<1925–1935–1936–1945–1946–1954). Trends were examined using joinpoint regression and described as average annual percent change (AAPC: overall change 1997–2014) and annual percent change (APC: in-between infection points). Primary analyses were unadjusted. All analyses (unadjusted and adjusted for demographics/lifestyle) were weighted to produce nationally representative estimates. Statistical procedures accounted for the complex survey design.
Results
Among men ages 60+, unadjusted prevalence of current drinking trended upward, on average, 0.7% per year (AAPC, p=0.02); average volume and prevalence of binge drinking remained stable. Adjusted results were similar. Among women age 60+, unadjusted prevalence of current drinking trended upward, on average, 1.6% per year (AAPC, p<0.0001) but average volume remained stable; prevalence of binge drinking increased, on average, 3.7% per year (AAPC, p<0.0001). Adjusted results were similar. Trends varied by age group and birth cohort. Among men born 1946–1954 unadjusted prevalence of current drinking trended upward, on average 2.4% per year (AAPC, p=0.02); adjusted results were non-significant.
Conclusions
Our finding of upward trends in drinking among adults ages 60+, particularly women, suggests the importance of public health planning to meet future needs for alcohol-related programs.
