Objectives: Sleep is a vital component for overall health and well-being, and it plays an essential role in social, physical, psychological, and cognitive health. This study aimed to appraise the sleep quality in medical and science students during the COVID-19 pandemic.

Methods: This questionnaire-based cross sectional study was conducted in the Department of Physiology, College of Medicine, King Saud University, Riyadh, Saudi Arabia, during September-December 2020. In this study, a validated self-administered electronic questionnaire was distributed to 1000 students, 782 (78.2%) of whom completed the study. The selection of students was based on using the stratified random sampling. The Pittsburgh Sleep Quality Index (PSQI) instrument scale was used to assess the sleep quality among medical and general sciences students. 

Results: Out of 782 respondents, 410 (52.4%) were medical students, and 372 (47.6%) were science students, including Physics, Chemistry, Mathematics, Statistics, Botany, and Zoology. Among the medical students, 143 (34.9%) were in pre-clinical years (1st and 2nd), while 266 (64.9%) of them were in clinical years (3rd, 4th, and 5th). Among all medical and general sciences students, it was found that 669 (85.5%) had poor sleep quality with a mean PSQI global score (mean 8.356) among them 336 (50.2%) were medical, and 333 (49.8%) were science students. Science students’ sleep quality was poorer (mean 8.78) than their medical counterparts (mean= 7.93).

Conclusion: The COVID-19 pandemic has a significant negative impact on students’ mental health and sleep quality. Both medical and general science students showed alarming levels of sleep deprivation and concerning low sleep quality during the COVID-19 pandemic. The sleep deprivation among students may be due to the sudden change of pedagogy in education driven by the COVID-19 pandemic. Sleep quality is quite a critical issue to be evaluated and addressed nationally and globally.
