Sleep disorders can have a critical effect on health and academic performance. This study aimed to estimate the prevalence and academic impact of various sleep disorders on university students by gender. This crosssectional study was conducted between May and September 2019. The prevalence of sleep disorders was assessed using the validated SLEEP-50 Questionnaire. Overall, 637 university students participated in the study (response rate: 100%); of these, 368 (57.8%) were female and 455 (71.4%) were > 20 years old. A total of 433 students (68.0%) had grade point averages (GPAs) of 2-3, whereas 20 (3.1%) had GPAs of < 2. The most common sleep disorders were narcolepsy, restless leg syndrome, insomnia, and obstructive sleep apnoea, whereas sleepwalking and nightmares were infrequent. Sleep disorders were significantly associated with low GPA among female students. University students are at risk for sleep disorders, with such disorders associated with decreased academic performance among females.
