Materials and Methods:
The study was conducted in a private medical
college in Tamil Nadu. This study is a cross-sectional
study. The sample size was calculated using the d-
squared formula and calculated to be 400. Data was
collected using the self-reportable sleep and Daytime
Habits Questionnaire (S&DHQ). It covered
demographic characteristics (4 questions) and sleep and
daytime habits (24 questions). The supplement includes
information about lifestyle and academic progress on a
four-point scale. The ‘Effects of sleep deprivation’
section contains 6 questions and focuses on the ill-effects
of sleep deprivation.
The S&DHQ was used to study sleep problems,
assess sleep quality and ill-effects of sleep deprivation in
young medical students. The subjective sleep quality of
students was as follows: excellent- 12 percentile; good-
38 percentile; satisfactory- 34 percentile; poor-13
percentile; very poor- 2 percentile.
The results of the study depict that approximately
50 percentage of medical students have sleep
deprivation. There was no association between sleep
quality and mode of study. There was a high association
between sleep quality and academic progress (‘p’ lesser
than 0.0001). The most common sleep disorders were
snoring and waking up because of nightmares.
