睡眠质量对认知能力有显着影响，并受到压力等多种因素的影响。与理想情况相反，医学生和住院医师在应该获得最大学习量的时候却遭受睡眠不足和压力。为了检验睡眠质量和学业成绩之间的关系，144 名参加临床前委员会考试的医学生回答了一项关于他们的主观睡眠质量（匹兹堡睡眠质量指数。PSQI）、成绩和三个不同时间点（学期、考试前和考试后）主观压力的调查。学业成绩与考前的压力和睡眠质量相关（r = 0.276，p < 0.001 和 r = 0.158，p < 0.03，请注意，低成绩意味着低睡眠质量和高压力），但与学期和考试后的压力或睡眠质量无关。 59% 的参与者在考试准备期间表现出临床相关的睡眠障碍 (PSQI > 5)，而学期期间和考试后的比例分别为 29% 和 8%。这项研究表明，在医学生中，并不是睡眠质量普遍较差的学生在医学委员会考试中表现较差。相反，考试成绩较差的学生似乎压力更大，睡眠质量也较差。然而，睡眠质量差也可能会对考试成绩产生负面影响，形成恶性循环。此外，医学生睡眠障碍的发生率应该成为干预的原因。 (C) 2012 Elsevier Ltd. 保留所有权利。
Sleep quality has significant effects on cognitive performance and is influenced by multiple factors such as stress. Contrary to the ideal, medical students and residents suffer from sleep deprivation and stress at times when they should achieve the greatest amount of learning. In order to examine the relationship between sleep quality and academic performance, 144 medical students undertaking the pre-clinical board exam answered a survey regarding their subjective sleep quality (Pittsburgh sleep quality index. PSQI), grades and subjective stress for three different time points: semester, pre- and post-exam. Academic performance correlated with stress and sleep quality pre-exam (r = 0.276, p < 0.001 and r = 0.158, p < 0.03, note that low performance meant low sleep quality and high stress), however not with the stress or sleep quality during the semester and post-exam. 59% of all participants exhibited clinically relevant sleep disturbances (PSQI > 5) during exam preparation compared to 29% during the semester and 8% post-exam. This study shows that in medical students it is not the generally poor sleepers, who perform worse in the medical board exams. Instead students who will perform worse on their exams seem to be more stressed and suffer from poor sleep quality. However, poor sleep quality may negatively impact test performance as well, creating a vicious circle. Furthermore, the rate of sleep disturbances in medical students should be cause for intervention. (C) 2012 Elsevier Ltd. All rights reserved.
