Sleep is essential for the body, mind, memory, and learning. However, the relationship between sleep quality, stress, and academic performance has not been sufficiently addressed in the literature. The aim of this study was to assess the quality of sleep and psychological stress among medical students and investigate the relationship between sleep quality, stress, and academic performance.
This cross-sectional study targeted all medical students in their preclinical years at a Saudi medical college in 2019. All students were asked to complete an electronic self-administered questionnaire comprising the Pittsburgh Sleep Quality Index (PSQI), the Kessler Psychological Distress Scale (K10), questions on the students' current overall grade point average, and other demographic and lifestyle factors. The associations between categorical variables were analyzed using Pearson's Chi-squared test at 0.05 significance level.
The mean PSQI score was 8.13 ± 3.46; 77% of the participants reported poor quality of sleep and 63.5% reported some level of psychological stress (mean K10 score: 23.72 ± 8.55). Poor quality of sleep was significantly associated with elevated mental stress levels ( < 0.001) and daytime naps ( = 0.035). Stepwise logistic regression model showed that stress and daytime nap were associated with poor sleep quality. Whereas, poor sleep or stress did not show any significant association with academic performance.
Poor sleep quality was significantly associated with elevated levels of strees. However, they did not show any statistically significant relationship with academic performance.
睡眠对身体、大脑、记忆和学习至关重要。然而，睡眠质量、压力与学业成绩之间的关系在文献中尚未得到充分探讨。本研究的目的是评估医学生的睡眠质量和心理压力，并调查睡眠质量、压力与学业成绩之间的关系。
这项横断面研究针对2019年沙特一所医学院临床前阶段的所有医学生。所有学生都被要求完成一份电子自填问卷，问卷包括匹兹堡睡眠质量指数（PSQI）、凯斯勒心理困扰量表（K10）、关于学生当前总体平均绩点的问题，以及其他人口统计学和生活方式因素。分类变量之间的关联在0.05显著性水平下使用Pearson卡方检验进行分析。
PSQI平均得分为8.13±3.46；77%的参与者报告睡眠质量差，63.5%的参与者报告有一定程度的心理压力（K10平均得分：23.72±8.55）。睡眠质量差与精神压力水平升高（<0.001）和白天小睡（=0.035）显著相关。逐步逻辑回归模型显示，压力和白天小睡与睡眠质量差有关。然而，睡眠差或压力与学业成绩之间没有显示出任何显著关联。
睡眠质量差与压力水平升高显著相关。然而，它们与学业成绩之间没有显示出任何统计学上的显著关系。
