Quality of sleep among clinical medical students of Bayero university, Kano, Nigeria

Background: Sleep deprivation and disruptions are associated with both psychological and physiological disorders. Medical students have an increased risk for sleep deprivation. This study aimed to determine the quality of sleep among clinical medical students of Bayero University Kano (BUK). Materials and Methods: This is a cross-sectional study that was conducted between February and March 2019 among clinical students of BUK. The data were obtained using sociodemographic questionnaire as well as the Pittsburgh Sleep Quality Index (PSQI) and Epworth Sleepiness Scale (ESS) self-administered questionnaires. Two hundred questionnaires were administered to the students in their 4th, 5th, and 6th academic year. SPSS version 20 was used for the statistical analysis of the data collected. Results: A total of 181 questionnaires were completed out of the 200 that were administered, making a response rate of 90.5%. There were 114 males (63%) and 67 females (37%), giving a male-to-female ratio of 1.7:1, which is in keeping with the gender distribution of the students. The mean age (± standard deviation) of the students was 23.8 ± 2.9 years. The overall poor sleep quality was found to be 53.0% based on the PSQI, whereas the overall excessive daytime sleepiness was found to be 38.3% using the ESS. Poor sleep quality was found to be 61.1%, 51.7%, and 42.9% among the students in the 4th, 5th, and 6th academic years, respectively (P = 0.14). Excessive daytime sleepiness was found to be 45.8%, 41.7%, and 22.9% among the students in the 4th, 5th, and 6th academic years, respectively (P = 0.03). Conclusion: The prevalence of poor sleep quality is high among the clinical students of BUK.
