To Evaluate the Sleeping Habits and Sleep Patterns of First Year and Final Year Medical Students and Its Impact on their Yearly Performance

Objective: To evaluate the sleeping habits and sleep patterns of first year and final year medical students and its impact on their yearly performance. Material and Method: It was a cross-sectional study. The study involved 720 students from two medical colleges (310 males and 410 females; mean age = 19.5 to 24.5 years ± 1.5). A questionnaire was developed to analyze changes in sleep patterns over time, with questions on sleep habits answered as yes or no. Student performance was assessed through two yearly modular exams, CBA I and II. Results showed that on weekdays, 64.7% of students woke between 5:30-6:30 AM and 60% between 6:30-7:30 AM; on weekends, 35% woke between 7-8 AM and 65% between 12-1 PM. Significant differences were observed in habits such as sleeping arrangements, pre-sleep activities, and afternoon naps. No significant differences were found in the use of night lights or difficulty falling asleep early. Performance metrics showed similar results across theory and practical exams, with some discrepancies in practical scores for the second year in CBA-II.
