The prevalence of alcohol consumption among Australian secondary stude
nts in 1993 was estimated from a survey of 22 696 students aged betwee
n 12 and 17 years. A random, representative sample of schools from all
education systems (government, Catholic and independent) was selected
and a sample of 80 students from each school was randomly selected fr
om predetermined year levels. Students completed an anonymous, self-ad
ministered survey on their drinking behaviours. Results showed that dr
inking was common, with 46% of female and 50% of male 17-year-olds hav
ing drunk on at least one of the 7 days prior to the survey (defined a
s current drinkers). Among 12-17-year-olds who were current drinkers,
27% of males had five or more alcoholic drinks on at least one drinkin
g day (''heavy drinking'') while 43% of girls had had three or more dr
inks (''heavy drinking''). Among current drinkers aged 12-15 years, 10
% of boys and 12% of girls had ''binged'' (for boys drinking eight or
more drinks in one session, for girls having six or more drinks at one
session) while among current drinkers aged 16 and 17 years the corres
ponding proportions were 33% of boys and 30% of girls. After controlli
ng for age, sex, school type and state, the proportion of 12-15-year-o
lds who were current drinkers rose from 24% to 26% between 1990 and 19
93. Among 16 and 17-year-olds, the proportion of current drinkers in 1
993 (47%) was the same as that found in 1990, although there were more
heavy drinkers and binge drinkers in 1993 than in 1990.
