This study examines the prevalence of risky drinking and the association between risky drinking behaviors and risk groups of substance abuse among college freshmen. A total of 376 college freshmen (126 boys and 248 girls) in a Japanese university participated in the study. The subjects were asked to complete self-administered, anonymous questionnaires during their class. The number of participants who had used drugs was small. The following 2 items for substance abuse were included in the questionnaires: (1) those who had drug using peers who used drugs and (2) those who had been persuaded to use drugs by their peers. On the basis of the responses, the participants were classified into 3 groups: (1) high-risk group (HRG), which accounted for 1.4% of the subjects and comprised those who answered "yes" to both the above-mentioned two items; (2) risk group (RG), which accounted for 7.4% and comprised participants who answered "yes" to one of the two items; and (3) control group (CG), which accounted for 91.2% and comprised those who did not answer "yes" to either of the two items. Bivariate analyses were performed to evaluate the association between risky drinking behaviors and risk groups of substance abuse. The results of our study indicated that 87.0% of the participants reported lifetime alcohol use, and 69.4% reported the consumption of alcohol during the past 30 days. Of the former group, 21.4% had engaged in binge drinking, 8.6% had experienced alcohol-related harassment, 9.5% had experienced alcohol-induced blackouts, and 82.0% had experienced drinking alcohol with peers without adults. There were significant associations between risk groups of substance abuse and risky drinking such as binge drinking (p = 0.001), alcohol-induced blackouts (p = 0.020), alcohol-related harassment (p = 0.012), alcohol consumption during the past 30 days (p = 0.047). However, lifetime alcohol use (p = 0.264) and experience of drinking alcohol with peers without adults (p = 0.103) did not differ significantly. These findings indicated that risky drinking behavior such as binge drinking or alcohol-induced blackouts are associated with substance abuse among college freshmen. Substance abuse prevention programs for college students should address the health effects of risky drinking behaviors and train students how to avoid submission to peer pressure.
本研究调查了大学新生中危险饮酒的流行情况以及危险饮酒行为与药物滥用风险群体之间的关联。日本一所大学的376名大学新生（126名男生和248名女生）参与了该研究。研究对象被要求在课堂上完成自我填写的匿名问卷。使用过毒品的参与者数量较少。问卷中包含以下两项关于药物滥用的内容：（1）有吸毒同伴的人；（2）被同伴劝说吸毒的人。根据回答，参与者被分为三组：（1）高风险组（HRG），占研究对象的1.4%，包括对上述两项内容均回答“是”的人；（2）风险组（RG），占7.4%，包括对两项内容之一回答“是”的参与者；（3）对照组（CG），占91.2%，包括对两项内容均未回答“是”的人。进行了双变量分析以评估危险饮酒行为与药物滥用风险群体之间的关联。我们的研究结果表明，87.0%的参与者报告有终生饮酒经历，69.4%的参与者报告在过去30天内饮酒。在前一组中，21.4%的人有过暴饮行为，8.6%的人经历过与酒精相关的骚扰，9.5%的人经历过酒精引起的昏厥，82.0%的人有过与同龄人在无成年人陪伴下饮酒的经历。药物滥用风险群体与危险饮酒之间存在显著关联，如暴饮（p = 0.001）、酒精引起的昏厥（p = 0.020）、与酒精相关的骚扰（p = 0.012）、过去30天内饮酒（p = 0.047）。然而，终生饮酒经历（p = 0.264）和与同龄人在无成年人陪伴下饮酒的经历（p = 0.103）没有显著差异。这些发现表明，暴饮或酒精引起的昏厥等危险饮酒行为与大学新生的药物滥用有关。针对大学生的药物滥用预防项目应关注危险饮酒行为对健康的影响，并培训学生如何避免屈从于同伴压力。
