Assessing Sleep Quality and Its Effects on Academic Performance among University Students

Background and Objective: Insufficient sleep duration as well as quality is becoming endemic in our modern society. The time of going to bed and sleep quality and quantity are linked with students’ learning abilities and academic ac-complishment. Therefore, this paper firstly opted to measure the level of sleep quality of the students of Jahangirnagar University, Savar, Dhaka-1342, Bangladesh, and finally detect the association between quality of sleep and academic achievement among the students. Materials and Methods: The primary data were collected through a self-administered questionnaire from 334 students with a response rate about 84 percent during February to March 2019. Pittsburgh Sleep Quality Index (PSQI) was used to measure the sleep quality of the students. The percent distribution, descriptive statistics, and multiple regression were employed to identify the influence of the components of sleep quality on academic performance. Results: Only the sleep quality of one-fourth of the students was good. Moreover, sleep duration, subjective sleep quality, and daytime dysfunction were positively related to the academic performance; however, sleep latency, sleep disturbances, use of sleeping medications, and habitual sleep efficiency were inversely associated with the academic performance of the students. Conclusion: Academic performance of a student was related to the components of sleep quality. Thus, this study indi-cates that students with poor academic performance have problems regarding sleep issues. Medical advice should be followed to maintain a healthier lifestyle including adequate rest time. © 2020 Tehran University of Medical Sciences. All rights reserved.
