Drunk in public, drunk in private: the relationship between college students, drinking environments and alcohol consumption.

This study examines environmental differences in public (bars) and private (parties) drinking settings among of-age (21 and up years of age) and underage (18-20 years of age) college students attending college near the US/Mexico border. A random telephone survey of graduate and undergraduate students attending two large public universities in the southwestern United States was conducted during the 2000-2003 academic years. A university-based social science research laboratory conducted the telephone interviews with respondents who reported an occasion in the past 28 days where alcohol was being consumed (N = 4,964). The data were analyzed using ordinary least squares multiple regression. The results suggests that drinking settings contributed to the amount of alcohol consumed by respondents. Additionally, environmental factors contributing to drinking vary by setting. In general, having many people intoxicated at an event, BYOB parties, playing drinking games, and having illicit drugs available contribute to heavier drinking.
