Day drinking, or drinking during the daytime, is a term used colloquially in the media and among college students based on anecdotal evidence. Drinking at tailgate parties, generally thought to be a type of day drinking, tends to be particularly heavy and to achieve levels comparable to drinking on holidays and special occasions. The objective of this study was to assess how many and how often students day drink and whether day drinking days (i.e., days drinking began before 4:00 p.m.) were associated with heavy drinking, legal intoxication, negative alcohol-related consequences, and three risky substance use behaviors.
We conducted a longitudinal daily diary study of college students who were followed for their first seven semesters of college. The analytic sample includes 7,633 drinking days nested with 619 student drinkers. We used logistic and Poisson multilevel models to test associations between day drinking days and substance use outcomes and negative consequences.
Approximately 50% of drinkers drank durinng the day at least once, and day drinking occurred on 9% of drinking days. Greek organization participants reported significantly more day drinking days than non-participants. Day drinking days were characterized by heavy drinking as evidenced by strong, positive associations between day drinking and drinking to heavy episodic drinking (HED) and high-intensity drinking (HID) thresholds on a given day. In contrast, students were less likely to reach legal intoxication and experienced fewer negative alcohol-related consequences on day drinking days than days on which drinking began in the evening or nighttime. Students who reported day drinking more often throughout the study also reported having more days of drinking at the HED and HID thresholds and playing drinking games and mixed alcohol with energy drinks more frequently.
Day drinking was common among this sample of college students. Findings suggest that day drinking days may be characterized by heavy drinking and may be a behavior most typically engaged in by heavy drinkers, including members of Greek organizations.
日间饮酒，或白天饮酒，是媒体和大学生中根据传闻证据使用的一个术语。在车尾派对上饮酒，通常被认为是日间饮酒的一种类型，往往特别严重，达到与节假日和特殊场合相当的饮酒水平。本研究的目的是评估有多少学生和他们多久会日间饮酒，以及日间饮酒日（即饮酒开始于下午 4 点之前的日子）是否与豪饮、法定醉酒、负面的酒精相关后果以及三种危险的物质使用行为有关。
我们对大学生进行了一项为期七个学期的纵向每日日记研究，对这些学生进行了跟踪调查。分析样本包括 7633 个饮酒日，嵌套在 619 名学生饮酒者中。我们使用逻辑和泊松多层模型来测试日间饮酒日与物质使用结果和负面后果之间的关联。
大约 50%的饮酒者至少有一次在白天饮酒，而且有 9%的饮酒日是日间饮酒日。希腊组织参与者比非参与者报告的日间饮酒日明显更多。日间饮酒日的特点是豪饮，因为日间饮酒与当天饮酒达到重度暴饮（HED）和高度密集饮酒（HID）阈值之间存在强烈的正相关关系。相比之下，学生在日间饮酒日达到法定醉酒和经历负面的酒精相关后果的可能性比在晚上或夜间开始饮酒的日子要小。在整个研究期间报告日间饮酒更频繁的学生也报告称，在 HED 和 HID 阈值下饮酒的天数更多，更频繁地玩饮酒游戏和将酒精与能量饮料混合。
日间饮酒在本研究样本中很常见。研究结果表明，日间饮酒日可能以豪饮为特征，并且可能是最常被豪饮者，包括希腊组织成员参与的行为。
