Prepartying promotes heightened risk in the college environment: an event-level report.

Due to the emergence of research literature examining the prepartying behavior of college students, the present study examines students' varying drinking rates, blood alcohol levels (BALs), and alcohol-related consequences during two drinking events - one involving prepartying and one devoid of prepartying. Two-hundred and thirty-eight student drinkers completed an online drinking assessment detailing their two most recent drinking occasions involving and not involving prepartying. Participants responded to a series of questions regarding quantities consumed on the drinking day and occurrence of alcohol-related consequences. While men did not differ in drinking or estimated BALs, between the two drinking days, female participants drank significantly more drinks and reached higher BALs on the prepartying drinking day. Both males and females reported increased experience of alcohol-related consequences on the prepartying drinking day. In analyzing the prepartying drinking day specifically, we found that while men drink more alcohol during prepartying, but both men and women reached similar BALs during the event. Also, amount consumed during prepartying related to further drinking throughout the evening. It appears that prepartying may influence women to reach comparable levels of intoxication and alcohol-related consequences as their male peers. Quick drinking during prepartying may raise BALs and lead to alcohol-related consequences particularly for female students.
