酗酒是一个二分变量，允许研究人员根据特定的消费阈值将学生分类，通常是4（女性）或5（男性）饮料。超过狂欢阈值会增加与酒精相关的负面后果的风险。这些阈值的使用在大学饮酒的研究中发挥了至关重要的作用。虽然非常有价值，但狂饮变量的二分法删除了关于学生实际饮酒量的信息，使大学饮酒的特征不完整。本研究调查了2003年秋季美国14所学校10,424名新生第一学期自我报告的2周饮酒史。计算了达到4+/5+酗酒阈值的学生人数，以及达到酗酒阈值2倍（8+/10+饮酒）或3倍（12+/15+饮酒）的人数。Logistic回归分析用于探索性别差异，并评估是否经常酗酒者（每2周3次以上的暴饮）比不经常暴饮的人更有可能（每2周1-2次狂欢）以达到高峰的消费水平。大约5个男性中有1个消费了10+饮料，10个女性中有1个消费了8+饮料，是狂欢阈值的两倍，在过去的两周内至少有一次。在每个饮酒水平下都观察到性别差异，并且在较高的峰值水平下尤其大。经常暴饮暴食的人比不经常暴饮暴食的人更有可能消耗2到3倍的暴饮暴食阈值。这些发现表明，学校可能会在反对酒精滥用的斗争中取得更多进展，除了狂饮本身之外，还应关注极端饮酒行为。
Binge drinking is a dichotomous variable that allows researchers to sort students into categories based upon a specific threshold of consumption, commonly 4 (females) or 5 (males) drinks. Crossing the binge threshold increases the risk of negative alcohol-related consequences. The use of such thresholds has played a vital role in the study of college drinking. While extremely valuable, the dichotomous nature of binge drinking variables removes information about how heavily students actually drink, leaving the characterization of college drinking incomplete. The present study examined patterns of alcohol use beyond the binge threshold.The data set consisted of self-reported 2-week drinking histories from 10,424 first-semester freshmen at 14 schools across the United States during the fall of 2003. The number of students who reached the 4+/5+ binge-drinking threshold was calculated, as was the number who reached 2 times (8+/10+ drinks) or 3 times (12+/15+ drinks) the binge threshold. Logistic regression analyses were used to explore gender differences and to assess whether frequent binge drinkers (3+ binges per 2 weeks) were more likely than infrequent binge drinkers (1-2 binges per 2 weeks) to reach high peak levels of consumption.Roughly 1 of 5 males consumed 10+ drinks and 1 of 10 females consumed 8+ drinks, twice the binge threshold, at least once in the previous 2 weeks. Gender differences were observed at every drinking level and were particularly large at higher peak levels. Frequent binge drinkers were more likely than infrequent binge drinkers to consume 2 or 3 times the binge threshold.A surprisingly large percentage of students, particularly males, drink at peak levels well beyond the binge threshold. Such findings suggest that schools might make additional progress in the battle against alcohol misuse by focusing on extreme drinking practices in addition to binge drinking per se.
