Objective: Sleep disturbance is a common problem faced by medical students affecting their physical and mental wellbeing. Lack of sleep during examinations puts a negative impact on their scores. The objective of this study is to determine students’ sleep pattern during night preceding examination and its correlation with their academic performance. Methods: This cross-sectional study was conducted from November to December 2013 among 4th and Final year MBBS students of Quaid-e-Azam Medical College, Bahawalpur, who were appearing in their annual examinations. Using non probability convenient sampling approach, 280 students were selected. Each of the 280 participants was allowed to pick out five pieces of lottery papers and they were asked the five questions resembling the number in the list of questions. Results: Out of the total 280 students, 74.6% were living in hostel and 25.4% were day scholars, and majority (63%) of them were females. Fifty two percent of the students either could not sleep at all or slept just for 1 to 1.5 hours while 12% slept for 5 to 6.5 hours. Two-third (66%) of the students was able enough to achieve one to two scores, and only 1.8% could succeed to get the maximum score of five. There was statistically significant correlation between hours of sleep preceding examination and the score achieved (r=0.701) and (p<0.001). Conclusion: Most of the medical students either do not sleep or sleep only for few hours preceding examination that result in poor performance in examinations.
