The aim of the study was to examine the relationship between sleep problems and objective driving behaviors of short-haul commercial truck drivers in Japan. One hundred and ten male short-haul commercial truck drivers’ sleep duration, sleep quality (Pittsburgh Sleep Quality Index), and frequency of sleepiness at the wheel were measured by survey in June 2019. In addition, their dangerous driving behaviors (i.e., overspeeding, sudden start and acceleration, sudden deceleration, and sudden braking) during June were calculated using digital tachograph data. Logistic regression analysis (LRA) was performed. The dependent variables were the presence/absence of dangerous driving behaviors, and sleep duration, sleep quality, and sleepiness were assigned as independent variables. Body mass index was adjusted as a confounding variable. LRA for sleep duration revealed that the “<5 h group” was associated with tendency of a higher adjusted odds ratio (2.87, 95% confidence interval = 0.87–9.45, p = 0.08) for sudden braking compared with the “6 h group.” LRA for sleep quality revealed that the “poor quality group” was associated with a higher adjusted OR (2.56, 95% CI = 1.09–6.01) for sudden braking compared with the “normal quality group.” LRA for the frequency of sleepiness revealed that the “frequently group” was associated with a higher adjusted OR (5.15, 95% CI = 1.10–24.13) for sudden braking compared with the “never group.” Nevertheless, sleep problems were nonsignificantly associated with other dangerous driving behaviors. Truck drivers with poor sleep quality and/or frequent sleepiness at the wheel displayed a 2.5–5.1 times greater risk of sudden braking than did drivers without these sleep problems.

该研究的目的是研究日本短途商用卡车司机的睡眠问题与客观驾驶行为之间的关系。通过2019年6月的调查，对110名男性短途商用卡车驾驶员的睡眠时间，睡眠质量（匹兹堡睡眠质量指数）和方向盘上的嗜睡频率进行了测量。此外，他们的危险驾驶行为（即超速驾驶） ，使用数字行驶记录仪数据计算了6月份的突然启动和加速，突然减速和突然制动）。进行逻辑回归分析（LRA）。因变量是危险驾驶行为的有无，睡眠时间，睡眠质量和嗜睡被指定为自变量。体重指数被调整为一个混杂变量。 与“ 6小时组”相比，突然制动的p = 0.08）。LRA的睡眠质量显示，与“正常质量组”相比，“质量较差组”与突然制动的校正后OR（2.56，95％CI = 1.09–6.01）相关。关于困倦频率的LRA显示，与“从不”组相比，“经常组”与突然制动的调整后OR较高（5.15，95％CI = 1.10–24.13）。然而，睡眠问题与其他危险的驾驶行为无关紧要。与没有这些睡眠问题的驾驶员相比，睡眠质量较差和/或经常困在车轮上的卡车驾驶员所表现出的突然制动风险要高2.5-5.1倍。
