Similarly, among current non-'harmful' drinkers in 2002-03, 17% become non-drinkers in 2004-05, 61% remain current non-'harmful’ drinkers, and 22% are ‘harmful’ drinkers. The proportion of 'harmful' drinkers varies by age: 47% in the age group 18-24, 27% in ages 25-44, 17% in ages 45-64, 8% in ages 65 or above. These findings suggest that young adults are more affected by 'harmful' drinking behaviours compared to other age groups. Figure 9 shows overall (population) rates in men and women, Figure 10 shows trends in HED in men and women by age group. The NHANES data show a clear increase in HED in the age group 20-24, while NSDUH data show a significantly milder, or no increase. Weekly limit is 14 drinks per week for women and 21 for men.
