Title Excessive daytime sleepiness among Japanese public transportation drivers engaged in shiftwork
Bibliographic information Aug. 2010, Vol.52, No.8, p.813-818. Illus. 52 ref.
Abstract The objective of this study was to explore the actual condition of sleep disorders underlying subjective excessive daytime sleepiness (EDS) among 3109 train and bus drivers engaged in shiftwork. Clinical diagnoses were carried out on the 147 drivers who claimed to have subjective EDS and 285 drivers who were judged to have obstructive sleep apnoea syndrome (OSAS), based on the screening process. Among these subjects, the prevalence of OSAS was 3.7% and that of shiftwork disorder (SWD) was 1.5%. SWD was common among drivers who had EDS (32.7% of drivers with EDS), and their EDS severity was higher than that of OSAS drivers. The drivers with SWD were mostly young and neither obese nor hypertensive. Encouraging awareness of SWD and OSAS could be necessary to prevent sleepiness-related accidents.
