title: [Sleep habits of medical students, physicians and nurses regarding age, sex, shift work and caffein consumption].
abstract: The aim of this study was to evaluate sleep habits of nurses, medical students, and physicians and to explore whether they are influenced by age, sex, shift work, and caffeine consumption. The questionnaire was derived from the MEDSleep Survey. A total of 453 respondents were surveyed: second-year medical students (130); physicians at the postgraduate study program (68); specialists (162); nurses (93). Results of our study indicate that hours of sleep needed for feeling rested depends on age and gender. Younger respondents and women in the study need longer sleep to feel rested (7.5 hours and more) than older ones and males who need less than 7.5 hours of sleep. Among medical professionals a need for sleep differs related to work demands and work schedule. Nurses need more sleep than physicians (chi2 = 38.57, p < 0.001). Female nurses need more sleep for feeling rested than female physicians (chi2 = 18.18, p < 0.001), and sleep longer during the weeknights (chi2 = 33.78, p < 0.001) and weekends (chi2 = 28.06, p < 0.001). The respondents that consume caffeine have more trouble staying awake while listening to lectures or learning (chi2 = 9.37, p = 0.009), and while driving a car (chi2 = 14.56, p = 0.001). The results indicate that sleep habits are related to age, sex and caffeine consumption.
