Inadequate sleep and heavy alcohol use have been associated with negative outcomes among college students; however, few studies have examined the interactive effects of sleep and drinking quantity in predicting alcohol-related consequences. This study aimed to determine if adequate sleep moderates the prospective association between weekly drinking quantity and consequences.
College students (N=568) who were mandated to an alcohol prevention intervention reported drinks consumed per week, typical sleep quantity (calculated from sleep/wake times), and perceptions of sleep adequacy as part of a larger research trial. Assessments were completed at baseline and one-, three-, and five-month follow-ups.
Higher baseline quantities of weekly drinking and inadequate sleep predicted alcohol-related consequences at baseline and one-month follow-up. Significant interactions emerged between baseline weekly drinking quantity and adequate sleep in the prediction of alcohol-related consequences at baseline, one-, three-, and five-month assessments. Simple slopes analyses revealed that weekly drinking quantity was positively associated with alcohol-related consequences for those reporting both adequate and inadequate sleep, but this association was consistently stronger among those who reported inadequate sleep.
Subjective evaluation of sleep adequacy moderates both the concurrent and prospective associations between weekly drinking quantity and consequences, such that heavy-drinking college students reporting inadequate sleep experience more consequences as a result of drinking. Research needs to examine the mechanism(s) by which inadequate sleep affects alcohol risk among young adults.
睡眠不足和大量饮酒与大学生的负面后果有关；然而，很少有研究探讨睡眠和饮酒量在预测与酒精相关后果方面的交互作用。本研究旨在确定充足的睡眠是否会调节每周饮酒量与后果之间的前瞻性关联。
作为一项更大规模研究试验的一部分，被要求参加酒精预防干预的大学生（N = 568）报告了每周饮酒量、典型睡眠量（根据入睡/起床时间计算）以及对睡眠充足性的感知。在基线以及1个月、3个月和5个月随访时完成评估。
较高的基线每周饮酒量和睡眠不足可预测基线及1个月随访时与酒精相关的后果。在基线、1个月、3个月和5个月评估中，基线每周饮酒量与充足睡眠之间在预测与酒精相关后果方面出现了显著的交互作用。简单斜率分析表明，对于报告睡眠充足和不足的人，每周饮酒量与酒精相关后果均呈正相关，但这种关联在报告睡眠不足的人中始终更强。
对睡眠充足性的主观评估调节了每周饮酒量与后果之间的同时期和前瞻性关联，以至于报告睡眠不足的重度饮酒大学生因饮酒而经历更多后果。研究需要探讨睡眠不足影响年轻人酒精风险的机制。
