Results from the 1995 National College Health Risk Behavior Survey, wh
ich monitored health risk behaviors among US college and university un
dergraduates, suggest that many students' behaviors increase their lik
elihood of adverse health outcomes. During the 30 days preceding the s
urvey, 34% of the participants had consumed five or more alcoholic dri
nks on at least one occasion, and 27% had drunk alcohol and driven a c
ar. Thirty-one percent had smoked cigarettes regularly during their li
fetimes, 49% had ever used marijuana, 30% had used a condom during the
ir last sexual intercourse, 21% were overweight, and 38% had participa
ted in vigorous physical activity on 3 or more of the 7 days preceding
the survey. These data were analyzed by gender, age group, race and e
thnicity, and institution type. They can be used by those responsible
for the health and education of college students to reduce risks assoc
iated with the leading causes of mortality and morbidity.
