Sleep deprivation can have substantial consequences for college learning and achievement. However, prior studies on this topic are limited due to the reliance on small and convenience samples, the use of cross-sectional data, inadequate control for confounders, and the lack of outcome data from official school records. The present study used two waves of longitudinal data from the U.S. Wabash National Study (N = 3549) to examine the relationships between sleep deprivation and school-record grade point average (GPA) and college graduation. Random-effects and fixed-effects models were used to link sleep deprivation and GPA. Logistic regression was used to link sleep deprivation during the college years and college graduation. Results from the random-effects and fixed-effects models suggest that chronic sleep deprivation is associated with lower GPA. Students who experienced sleep deprivation from their freshman to senior years had a lower chance of graduation than students who were not sleep deprived. Furthermore, sleep deprivation during students' senior year was found to be more consequential for college graduation than sleep deprivation during their freshman year. Findings suggest that the ramifications of chronic sleep deprivation extend beyond short-term GPA; sleep deprivation predicts the likelihood of obtaining a college degree.
睡眠剥夺会对大学生的学习和成绩产生重大影响。然而，由于依赖小样本和方便样本、使用横断面数据、对混杂因素的控制不足以及缺乏来自官方学校记录的结果数据，该主题的先前研究受到限制。本研究使用来自美国 Wabash 国家研究的两波纵向数据（N=3549），研究睡眠剥夺与学校记录的平均绩点（GPA）和大学毕业之间的关系。随机效应和固定效应模型用于将睡眠剥夺与 GPA 联系起来。逻辑回归用于将大学期间的睡眠剥夺与大学毕业联系起来。随机效应和固定效应模型的结果表明，慢性睡眠剥夺与较低的 GPA 相关。与没有睡眠剥夺的学生相比，从大一到大四经历睡眠剥夺的学生毕业的机会较低。此外，研究发现，与大一相比，学生大四的睡眠剥夺对大学毕业的影响更大。研究结果表明，慢性睡眠剥夺的后果不仅限于短期 GPA；睡眠剥夺预测获得大学学位的可能性。
