Excessive drinking by college students is a major public health problem in Japan. However, data on heavy episodic drinking (HED) and nomihodai, a several-hour all-you-can-drink system, are scarce. We surveyed the drinking behavior of undergraduate and graduate students at 35 colleges, and examined the association between HED and use of nomihodai. The study used a cross-sectional design conducted by a self-administered questionnaire. From December 2016 to March 2017, we sampled undergraduate and graduate students aged 20 or older at 35 colleges in the Kanto area, including Tokyo. The following items were measured: 1) frequency of drinking; 2) frequency of binge drinking in the past year; 3) nomihodai use; 4) the number of drinks consumed when using or not using nomihodai; and 5) sex and age for demographic data. Paired t-test was used to compare means between use and non-use state of nomihodai. The Fisher's exact test was used to evaluate the significance of the distribution difference between the two types of states. A total of 511 subjects completed the questionnaire, including 274 men and 237 women. The amount of drinking was increased 1.8-fold (85.9 ± 49.7 g vs. 48.2 ± 29.5 g) among men and 1.7-fold (63.7 ± 39.3 g vs. 36.5 ± 26.7 g) among women during nomihodai use, comapred with non-use states. Among them, 109 (39.8%) men and 71 (30.3%) women reported HED only at nomihodai states. These data suggest that the use of nomihodai system may lead to excessive drinking among college students.
在日本，大学生过度饮酒是一个主要的公共卫生问题。然而，关于重度间歇性饮酒（HED）以及“畅饮几个小时”这种任饮制的数据却很匮乏。我们对35所高校的本科生和研究生的饮酒行为进行了调查，并研究了重度间歇性饮酒与任饮制使用之间的关联。该研究采用自行填写问卷的横断面设计。在2016年12月至2017年3月期间，我们在包括东京在内的关东地区的35所高校中，对20岁及以上的本科生和研究生进行了抽样。测量了以下项目：1）饮酒频率；2）过去一年中暴饮的频率；3）任饮制的使用情况；4）使用或不使用任饮制时的饮酒量；5）用于人口统计学数据的性别和年龄。采用配对t检验来比较任饮制使用和不使用状态之间的均值。使用Fisher精确检验来评估两种状态之间分布差异的显著性。共有511名受试者完成了问卷，其中包括274名男性和237名女性。与不使用任饮制的状态相比，在使用任饮制期间，男性的饮酒量增加了1.8倍（85.9±49.7克对48.2±29.5克），女性的饮酒量增加了1.7倍（63.7±39.3克对36.5±26.7克）。其中，109名（39.8%）男性和71名（30.3%）女性仅在任饮制状态下报告有重度间歇性饮酒。这些数据表明，任饮制的使用可能会导致大学生过度饮酒。
