J Med Sci Jan ;31(03):235-9.

Objectives: To assess students` sleep quality and to find the association of students` academic performance with sleep quality. Materials and Methods: It is a cross-sectional study conducted in three public sector institutes: Khyber Medical College Peshawar (KMC), Khyber College of Dentistry (KCD) Peshawar, and the University of Peshawar (UOP). A convenience sampling technique was used, and a sample size of 139 was calculated using the Cochran formula. Data collection was done from September 10, 2022 to October 1, 2022. A self-administered well-validated questionnaire was used to inquire about students` personal and lifestyle characteristics and academic performance and also included the Pittsburgh Sleep Quality Index (PSQI). A score equal to or greater than 5 on the PSQI scale signifies poor sleep quality. The chi-square test and Pearson correlation were applied to determine statistical significance. The data analyses were conducted using IBM`s SPSS Statistical Software for Windows (IBM SPSS Version 21, Chicago, IL, USA). Results: Out of 139 participants, 29 (20.9%) had good-quality sleep, while 110 (79.1%) were poor sleepers. However, we could find no significant association between sleep quality and academic performance (p = 0.194; r = - 0.049) Conclusion: A very high percentage of students had poor sleep quality. However, we could establish no association with academic performance.
