This study assessed the association of sleep quality with academic performance among university students in Ethiopia.
This cross-sectional study of 2,173 college students (471 female and 1,672 male) was conducted in two universities in Ethiopia. Students were selected into the study using a multistage sampling procedure, and data were collected through a self-administered questionnaire. Sleep quality was assessed using Pittsburgh Sleep Quality Index, and academic performance was based on self-reported cumulative grade point average. The Student's "t" test, analysis of variance, and multiple linear regression were used to evaluate associations.
We found that students with better sleep quality score achieved better on their academic performance (P value = 0.001), while sleep duration was not associated with academic performance in the final model.
Our study underscores the importance of sleep quality on better academic performance. Future studies need to identify the possible factors which influence sleep quality other than the academic environment repeatedly reported by other literature. It is imperative to design and implement appropriate interventions to improve sleep quality in light of the current body of evidence to enhance academic success in the study setting.
本研究评估了埃塞俄比亚大学生睡眠质量与学业成绩之间的关联。
这项对2173名大学生(471名女性和1672名男性)开展的横断面研究在埃塞俄比亚的两所大学进行。采用多阶段抽样程序选取学生参与研究,并通过自填式问卷收集数据。使用匹兹堡睡眠质量指数评估睡眠质量,学业成绩基于自我报告的累积平均绩点。采用学生“t”检验、方差分析和多元线性回归来评估关联。
我们发现睡眠质量得分较高的学生学业成绩更好(P值 = 0.001),而在最终模型中睡眠时间与学业成绩无关。
我们的研究强调了睡眠质量对取得更好学业成绩的重要性。未来的研究需要找出除其他文献反复提及的学术环境之外可能影响睡眠质量的因素。根据当前的证据体系,设计并实施适当的干预措施以改善睡眠质量从而提高学习环境中的学业成就势在必行。
