Sleep is crucial for college students' well-being. Although recommended sleep duration is between 7-9 hours per day, many students do not sleep that much. Scholar demands are among the causes of observed sleep deprivation in youth. We explored the influence of having a school test on previous night sleep in first-year students and the association of sleep duration and test performance. We ran two surveys in freshman students of the Universidad de la República, Montevideo, Uruguay: 1) 97 students of the School of Sciences who took the test at the same time; and 2) 252 School of Psychology students who took the test in four successive shifts. More than 1/2 of the participants (survey #1) and almost 1/3 (survey #2) reported short regular sleep duration (< 7h). In both samples, the sleep duration of the night before the test was reduced with respect to regular nights (survey #1: 2.1 ± 0.2 h, p < 0.001; survey #2: between 1.7 ± 0.4 h and 3.6 ± 0.3 h, all p < 0.001), with more than 10% of the students who did not sleep at all. In survey 2, sleep duration increased in later shifts (F (3,248) = 4.6, p = 0.004). Using logit regressions, we confirmed that sleep duration was positively related to test scores in both samples (survey #1: exp B = 1.15, p < 0.001; pseudo-R2 = 0.38; survey #2: exp B = 1.03, p < 0.001; pseudo-R2 = 0.25). Delaying test start time may prevent the reduction in sleep duration, which may also improve school performance. In addition, educational policies should include information for students about the impact of sleep on learning and of the consequences of reduced sleep duration.
睡眠对大学生的健康至关重要。尽管建议的睡眠时间为每天 7-9 小时，但许多学生并没有睡那么多。学业要求是导致年轻人睡眠不足的原因之一。我们探讨了学校考试对上届学生前一晚睡眠的影响，以及睡眠持续时间和考试成绩之间的关系。我们在乌拉圭蒙得维的亚的共和国大学进行了两项针对大一新生的调查：1）同时参加考试的 97 名科学学院学生；2）分四个连续班次参加考试的 252 名心理学学院学生。超过一半的参与者（调查 1）和近三分之一的参与者（调查 2）报告说常规睡眠时间较短（<7 小时）。在这两个样本中，与常规夜晚相比，考试前一晚的睡眠时间减少（调查 1：2.1±0.2 小时，p<0.001；调查 2：1.7±0.4 小时至 3.6±0.3 小时，均 p<0.001），超过 10%的学生根本没有睡觉。在调查 2 中，睡眠持续时间在后几轮中增加（F（3,248）=4.6，p=0.004）。使用对数回归，我们确认睡眠持续时间与两个样本中的考试成绩呈正相关（调查 1：exp B=1.15，p<0.001；伪 R2=0.38；调查 2：exp B=1.03，p<0.001；伪 R2=0.25）。延迟考试开始时间可能会防止睡眠持续时间减少，这也可能提高学校成绩。此外，教育政策应包括有关睡眠对学习的影响以及睡眠持续时间减少的后果的信息。
