The objective of this study was to analyze the effect of individual circadian preferences of drivers with fixed night work schedules on sleep patterns.
A total of 123 professional drivers, 32 indifferent preference drivers and 91 morning preference drivers of an intermunicipality and interstate bus transportation company were evaluated. All drivers underwent polysomnographic recordings after their shifts. Furthermore, they filled out a questionnaire that contained sociodemographic and health questions. The Horne and Östberg questionnaire was used to assess the subjects' morningness-eveningness preference.
The mean age was 42.54 ± 6.98 years and 82 (66.66%) of the drivers had worked for ≥15 years. A significant effect on rapid eye movement (REM) was observed in the morning preference drivers. They showed an increased sleep latency and an REM sleep percentage of 5% of the total REM time. This reveals a significant effect on sleep architecture associated with work time.
The drivers reported that morning preference had a significant effect on their sleep pattern indicating less REM sleep and longer REM sleep latency in the morning preference group. Thus, it is important to evaluate interactions between individual aspects of health and other parameters, such as sleep quality and work organizational factors, to promote night shift workers' health and well-being.
本研究旨在分析固定夜间工作时间表的驾驶员个体昼夜节律偏好对睡眠模式的影响。
对一家市际和州际巴士运输公司的 123 名专业驾驶员、32 名无差异偏好驾驶员和 91 名晨型偏好驾驶员进行评估。所有驾驶员在轮班后进行多导睡眠记录。此外，他们填写了一份包含社会人口统计学和健康问题的问卷。使用 Horne 和 Östberg 问卷评估受试者的晨型-晚型偏好。
平均年龄为 42.54 ± 6.98 岁，82 名（66.66%）驾驶员的工作年限≥15 年。在晨型偏好驾驶员中观察到快速眼动（REM）睡眠有显著影响。他们的睡眠潜伏期增加，REM 睡眠时间占 REM 总时间的 5%。这表明与工作时间相关的睡眠结构受到显著影响。
驾驶员报告称，晨型偏好对他们的睡眠模式有显著影响，表明晨型偏好组的 REM 睡眠时间减少，REM 睡眠潜伏期延长。因此，评估健康个体方面与其他参数（如睡眠质量和工作组织因素）之间的相互作用，对于促进夜班工人的健康和福祉非常重要。
