To assess sleep habits among healthy medical students in a third world country, and to correlate it with daytime sleepiness.
Medical students in Pakistan from three medical schools filled out a sleep diary, Epworth Sleepiness Scale (ESS), Stanford Sleepiness Scale (SSS), Pittsburgh Sleep Quality Index (PSQI) as well as Berlin Questionnaire (BQ). Questionnaires that were completely filled were included for statistical analysis.
A total of 187 medical students filled out the questionnaires. 75 students (40.1%) were “poor sleepers” (PSQI > 5). 64.5% of the poor sleepers were female as compared to only 49.4% of the normal sleepers (p < 0.005). Poor sleepers, compared to normal sleepers, had a lower mean SSS (2.6 +/− 1.2 vs. 2.1 +/− 1.1 respectively; p < 0.05) and also had lower total sleep times –(5.4 +/− 1.0 hours vs. 7.02 +/− 1.3 hours respectively; p < 0.05). Poor sleep quality is very common among medical students in Pakistan. It is associated with female gender, inadequate sleep, and daytime sleepiness. OSA is more prevalent in subjects with “poor sleep”.

Medical students in Pakistan may need to be educated about the importance of sleep and given more information about sleep hygiene measures and be evaluated for sleep related breathing disorder if symptomatic.
