To explore the actual condition of sleep disorders underlying subjective excessive daytime sleepiness (EDS) among train and bus drivers engaged in shiftwork.
This study targeted 3109 public transportation drivers. Clinical diagnoses were made based on 147 drivers who claimed to have subjective EDS, and 285 drivers who were judged to have obstructive sleep apnea 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.
探讨轮班作业的铁路和公交司机中主观日间嗜睡（EDS）所伴发的睡眠障碍的实际情况。
本研究以 3109 名公共交通司机为研究对象。根据主观 EDS 自述的 147 名司机和基于筛查过程判断的阻塞性睡眠呼吸暂停综合征（OSAS）的 285 名司机进行临床诊断。
这些研究对象中，OSAS 的患病率为 3.7%，而轮班工作障碍（SWD）的患病率为 1.5%。SWD 在有 EDS 的司机中很常见（EDS 司机中 32.7%），他们的 EDS 严重程度高于 OSAS 司机。SWD 司机大多年轻，既不肥胖也不患有高血压。
为了预防与困倦相关的事故，有必要提高对 SWD 和 OSAS 的认识。
