Fatigue and sleepiness are inter-related and common among road transport drivers. In this study, sleep deprivation and fatigue among chemical transportation drivers were examined.
A cross-sectional study surveying 107 drivers from three hazardous types of chemical production and transportation industries (nonflammable gases, flammable gases, and flammable liquids) was conducted. Data on sleep deprivation were collected using questionnaires of the Stanford Sleeping Scale and the Groningen Sleep Quality Scale. Fatigue was assessed using an interview questionnaire and a flicker fusion instrument.
Chemical drivers had a mean sleeping scale (Stanford Sleeping Scale) of 1.98 (standard deviation 1.00) and had a mean score of 1.89 (standard deviation 2.06) on the Groningen Sleep Quality Scale. High-risk drivers had higher scores in both the Stanford Sleeping Scale and the Groningen Sleep Quality Scale with a mean score of 2.59 and 4.62, respectively, and those differences reached statistical significance ( < 0.05). The prevalence of fatigue, as assessed through a critical flicker fusion analyzer, subjective fatigue question, and either of the instruments, was 32.32%, 16.16%, and 43.43%, respectively. Drivers who slept <7 hours and had poor sleep quality were found to have more fatigue than those who slept enough and well. Drivers who had a more sleepiness score resulted in significantly more objective fatigue than those who had a less sleepiness score.
Sleep quality and sleeping hour can affect a driver's fatigue. Optimization of work-rest model should be considered to improve productivity, driver retention, and road safety.
疲劳和困倦相互关联，在道路运输司机中很常见。本研究调查了化学品运输司机的睡眠剥夺和疲劳情况。
进行了一项横断面研究，对来自三种危险类型的化学品生产和运输行业（不可燃气体、可燃气体和易燃液体）的107名司机进行了调查。使用斯坦福睡眠量表和格罗宁根睡眠质量量表问卷收集睡眠剥夺数据。通过访谈问卷和闪烁融合仪评估疲劳情况。
化学品运输司机的平均睡眠量表（斯坦福睡眠量表）评分为1.98（标准差1.00），在格罗宁根睡眠质量量表上的平均得分为1.89（标准差2.06）。高风险司机在斯坦福睡眠量表和格罗宁根睡眠质量量表上的得分更高，平均得分分别为2.59和4.62，差异具有统计学意义（<0.05）。通过临界闪烁融合分析仪、主观疲劳问题以及这两种仪器中的任何一种评估的疲劳患病率分别为32.32%、16.16%和43.43%。睡眠时间不足7小时且睡眠质量差的司机比睡眠充足且良好的司机更容易疲劳。嗜睡得分较高的司机比嗜睡得分较低的司机客观疲劳程度明显更高。
睡眠质量和睡眠时间会影响司机的疲劳程度。应考虑优化工作休息模式，以提高工作效率、留住司机并保障道路安全。
