nts was administered in a two-stage (29 universities, 5,652 students)
random sample. All campuses and 3,810 (69%) students participated in t
he survey. in the 30 days preceding the survey, 36.7% of the students
had binged at least once while drinking; 25.3% had driven after consum
ing alcohol; 32% had ridden in a car with someone who had been drinkin
g; 17.6% had used marijuana; and 6% had carried a knife, gun, or club.
More than half of the students who were sexually active and not marri
ed or living with a primary partner had not used a condom the last tim
e they had sexual intercourse. Only 5% of regular bicycle riders alway
s wore a helmet. Fewer than half (44%) reported aerobic physical activ
