Aims To examine how membership in fraternities and sororities relates to the
prevalence and patterns of substance use in a national sample of full-time US
Design Nationally representative probability samples of US high school
seniors (modal age 18 years) were followed longitudinally across two follow-up
waves during college (modal ages 19/20 and 21/22).
Setting Data were collected via self-administered questionnaires from US high
school seniors and college students.
Participants The longitudinal sample consisted of 10 cohorts (senior years of
1988–97) made up of 5883 full-time undergraduate students, of whom 58%
were women and 17% were active members of fraternities or sororities.
Findings Active members of fraternities and sororities had higher levels of
heavy episodic drinking, annual marijuana use and current cigarette smoking
than non-members at all three waves. Although members of fraternities
reported higher levels than non-members of annual illicit drug use other than
marijuana, no such differences existed between sorority members and nonmembers.
Heavy episodic drinking and annual marijuana use increased
significantly with age among members of fraternities or sororities relative to
non-members, but there were no such differential changes for current cigarette
use or annual illicit drug use other than marijuana.
Conclusions The present study provides strong evidence that higher rates of
substance use among US college students who join fraternities and sororities
predate their college attendance, and that membership in a fraternity or sorority
is associated with considerably greater than average increases in heavy episodic
drinking and annual marijuana use during college. These findings have
important implications for prevention and intervention efforts aimed toward
college students, especially members of fraternities...
