The purpose of this study was to evaluate the sleep status of residents in neurology department in Korea. Methods: We recruited neurological residents of 12 university hospitals. They completed questionnaires including their sleep and work hours, sleep habit, Stanford Sleepiness Scale (SSS), Epworth Sleepiness Scale (ESS), and health problems. Results: We excluded the residents who were previously diagnosed with sleep disorders. One hundred and three residents (male 67, female 36) were analyzed. Average sleep duration on off duty days was 5.8±0.9 hours, on duty days was 4.6±1.3 hours and mean work hours was 14.6±2.3 hours. Average SSS score was 2.6±1.0 and ESS was 10.6±5.1. Group analyzed by training years showed short sleep duration in first and second years of training. ESS score was higher in first and second years compare to other years. Conclusions: Most neurological residents were suffering from sleep deprivation especially first and second years of training. They also reported more sleepiness and drowsiness during the daytime.
