Alcohol use disorder is a serious health problem in college students. Alcohol Use Disorders Identification Test (AUDIT) is a 10-item screening tool to assess alcohol consumption, drinking behaviors, and alcohol-related problems. AUDIT-C is a short version of AUDIT, consisting of consumption items 1-3. However, the optimal cutoff values of AUDIT and AUDIT-C for detecting excessive drinking are not available for Japanese college students. The aim of this study was to evaluate the validity of cutoff points of AUDIT and AUDIT-C for detecting moderate drinking, heavy drinking and binge drinking among Japanese college students. The cross-sectional study was based on an anonymous, self-administered questionnaire. In January 2017, we sampled college students and graduate students aged 20 years or older during annual health examinations at Mie University in Japan. Two thousand students underwent health examinations, and the eligible subjects were 1,600, including 152 (9.5%) moderate drinkers, 58 (3.6%) heavy drinkers and 666 (41.6%) binge drinkers. ROC (receiver operating characteristic) curve analysis showed that the optimal cutoff values for moderate drinking, heavy drinking and binge drinking were 5, 8 and 5 for men and 4, 7 and 4 for women in AUDIT; and 4, 7 and 4 for men and 4, 7 and 4 for women in AUDIT-C, respectively. Moderate drinking is considered unsafe drinking. Therefore, the optimal cutoff values for moderate drinking (5 for men and 4 for women in AUDIT and 4 for both sexes in AUDIT-C) are important parameters for prevention of alcohol use disorder in Japanese college students.
酗酒障碍是大学生中严重的健康问题。酒精使用障碍识别测试（AUDIT）是一种 10 项筛查工具，用于评估酒精摄入量、饮酒行为和与酒精相关的问题。AUDIT-C 是 AUDIT 的一个简短版本，由消费项目 1-3 组成。然而，对于日本大学生来说，AUDIT 和 AUDIT-C 检测过量饮酒的最佳截断值尚不清楚。本研究旨在评估 AUDIT 和 AUDIT-C 检测日本大学生适度饮酒、重度饮酒和 binge 饮酒的截断值的有效性。该横断面研究基于匿名、自我管理的问卷。2017 年 1 月，我们在日本三重大学的年度健康检查中对 20 岁或以上的大学生和研究生进行了抽样。2000 名学生接受了健康检查，合格的受试者为 1600 名，包括 152 名（9.5%）适度饮酒者、58 名（3.6%）重度饮酒者和 666 名（41.6%） binge 饮酒者。ROC（接受者操作特征）曲线分析显示，AUDIT 中男性中度饮酒、重度饮酒和 binge 饮酒的最佳截断值分别为 5、8 和 5，女性分别为 4、7 和 4；AUDIT-C 中男性中度饮酒、重度饮酒和 binge 饮酒的最佳截断值分别为 4、7 和 4，女性分别为 4、7 和 4。适度饮酒被认为是不安全的饮酒。因此，对于日本大学生来说，适度饮酒的最佳截断值（男性 AUDIT 为 5，女性 AUDIT 为 4，AUDIT-C 为两性均为 4）是预防酗酒障碍的重要参数。
