Abstract

Medical students do not sleep enough hours, they should study at night and, therefore, they have excessive daytime somnolence that could produce attention disorders affecting their academic performance. The objective was to determine the prevalence of excessive daytime somnolence and prevalence of poor quality in students of a private university in Ecuador, and the relation existing between these disorders and their academic performance. A cross-sectional study that included 219 undergraduate medical students, 57.5% of them, female. Spanish paper-based Epworth Somnolence Scale and the Pittsburgh Sleep Quality Index were applied. Sociodemographic variables were also measured. Statistical methods were performed to make comparisons between groups (comparison of proportions and means) and bivariate and multivariate regression logistic were performed to assess the association between academic performance and sleep quality after adjusting for other covariates. Excessive daytime somnolence occurred in 42.0% (95%CI 35–49) of students, slightly higher in women and 83.1% reported bad quality of sleep according to the Pittsburgh scale. It was found that 40.6% had a poor academic performance being alcohol consumption a risk factor for it. There was no statistical association between excessive daytime somnolence, poor sleep quality, and academic performance. Excessive daytime somnolence and bad quality of sleep are very common among medical students, but this disturbed sleep pattern seems no to be associated with poor academic performance.

摘要

医科学生睡眠不足，他们应该在晚上学习，因此白天睡眠过多，会产生注意力障碍，影响他们的学习成绩。目的是确定厄瓜多尔一所私立大学学生白天过度嗜睡和低劣质量的患病率，以及这些疾病与其学业成绩之间存在的关系。这项横断面研究包括219名本科医学生，其中女性占57.5％。应用西班牙的纸质爱华氏嗜睡量表和匹兹堡睡眠质量指数。还测量了社会人口统计学变量。进行统计学方法以进行组间比较（比例和均值的比较），并在对其他协变量进行调整后，进行二元和多元回归逻辑分析以评估学习成绩与睡眠质量之间的关联。根据匹兹堡量表，白天过度嗜睡的学生占42.0％（95％CI 35–49），女性略高，83.1％的学生报告睡眠质量差。发现40.6％的学生学习成绩差，因为饮酒是其危险因素。白天过度嗜睡，睡眠质量差和学习成绩之间没有统计学联系。在医学生中，白天过度嗜睡和睡眠质量低下非常普遍，
