Prevalence and factors associated with excessive daytime sleepiness among Malaysian medical students

Abstract

The purpose of our study was to ascertain the frequency of excessive daytime sleepiness (EDS) amongst medical students as well as the contributing variables. In Kelantan, Malaysia, at the School of Medical Sciences of Universiti Sains Malaysia, a cross-sectional research study was carried out. The Epworth drowsiness scale was used to gauge the degree of daytime drowsiness, and the depression, anxiety, and stress scale was used to gauge the degree of depression, anxiety, and stress. The related factors of EDS were analyzed using ordinal logistic regression. 311 individuals, or 84.5% of the total, submitted the questionnaire out of 368. 42.7% of people had EDS (95% CI: 0.52, 0.70). The associated factors of EDS included year of study (adjusted odds ratio [AOR]=0.55 [95% confidence interval [CI]: 0.33, 0.91]), race (Chinese) (AOR=0.58 [95% CI: 0.32, 0.97]), anxiety level (mild) (AOR=2.68 [95% CI: 1.26, 5.68]), anxiety level (moderate) (AOR=3.70 [95% CI: 1.76, 7.75]), anxiety level (severe) (AOR=4.76 [95% CI: 1.06, 21.42]), stress level (mild) (AOR=3.37 [95% CI: 1.47, 7.30]) and stress level (moderate) (AOR=5.42 [95% CI: 2.05, 14.35]). As for conclusion, associated factors such as year of study, race, anxiety and stress level were significantly found to be associated with EDS among medical students.
