By birth cohort, among men, prevalence decreased over time in all except the most recent cohort (1946–1954) where it was stable. Decreases of 9.2% and 5.7% (AAPC <0.0001 for both), respectively, were found in the <1925 and 1925–1935 birth cohorts. Among women, there were decreases in prevalence of binge drinking in the two earlier birth cohorts. Prevalence was stable in the two more recent cohorts. When we examined birth cohorts stratified by age groups between 1997 and 2014, based on non-overlapping confidence intervals, among women ages 60–64, prevalence of binge drinking was higher in the most recent birth cohort than in the 1925–1935 and 1936–1945 birth cohorts (Figure 2, Table S15); caveats are that data on older baby boomers were not available and that sample size for binge drinkers was limited.
