Background: Results from several studies suggest a global trend of sleep insufficiency among the youths. This study determines the sleep pattern of medical students. Methods: In a cross-sectional study, we used a modified self-administered questionnaire adapted from Pittsburg Sleep Quality Index to determine the sleep pattern of students in College of Health Sciences, University of Ilorin, Nigeria. Responses were submitted anonymously. Results: A total of 399 students participated in the study and their age ranged from 16 - 35 years.
Males constituted 64% of survey sample. The mean sleep duration of students were 6.4±0.84 hours during weekdays and 7.4±0.96 hours at weekends (p<0.05). Students went to bed later (23;15±1;30
hour) at weekends than during weekdays (22:58±1:30 hour). They also got up later from bed at weekends (6:42±1:28 hour) than during school days (05:36±1:09 hour) (p<0.05). Female students had significantly shorter sleep duration (6.9±0.98 hour) than males (7.4±0.9 hours) at weekend (p<0.05). About 30% of the respondents had problem falling asleep. Only 3.4% of the respondent had ever been involved in a sleep related accident, while 4% and 14% of students took cigarette
and alcohol, respectively. Conclusion: The study population had shorter sleep period than that recommended for their age. Gender had significant influence on their sleep habit. We recommend sleep educational programme from medical undergraduates.
