title: Sleep deprivation and drowsiness of medical residents and medical students.
abstract: OBJECTIVE
  to evaluate sleep quality and daytime sleepiness of residents and medical students.
  
  
  METHODS
  we applied a socio-demographic questionnaire, the Pittsburgh Sleep Quality Index (PSQI) and the Epworth Sleepiness Scale (ESS) to a population of residents and medical students.
  
  
  RESULTS
  hundred five residents and 101 undergraduate medical students participated. Residents presented higher mean PSQI (6.76±2.81) with poorer sleep quality when compared with undergraduates (5.90±2.39); Both had similar measures of sleepiness by ESS (p=0.280), but residents showed lower duration and lower subjective sleep quality.
  
  
  CONCLUSIONS
  medical students and residents presented sleep deprivation, indicating the need for preventive actions in the medical area.
