Abstract

Purpose: This study aimed to assess among hospital night workers (i) to what extent sleep quality, sleep duration and sleep disturbances overlap, and (ii) associations between sociodemographic factors, lifestyle factors and work characteristics and sleep components.

Methods: Data were used from 467 hospital night workers participating in the Klokwerk + study, a prospective cohort study with two measurements. Sleep quality was measured by the Pittsburgh Sleep Quality Index, sleep duration and sleep disturbances were measured by the Medical Outcomes Study Sleep Scale. The overlap between the three sleep measures was visualized with a Venn diagram and the proportions of overlap was calculated. Associations between independent variables (sociodemographic factors, lifestyle factors and work characteristics) and the three sleep outcomes were estimated using between-within Poisson regression models.

Results: About 50% of the hospital night workers had at least one poor sleep outcome. Overlap in poor sleep outcomes was apparent for 36.8% of these workers, while the majority had a poor outcome in one of the sleep components only (63.1%). Former smoking had a significant association with poor sleep quality. For most independent variables no associations with poor sleep outcomes were observed.

Conclusion: Our findings suggest that sleep quality, sleep duration and sleep disturbances are separate entities and should be studied separately. Lifestyle factors and work characteristics were generally not associated with poor sleep. Since these factors can have an acute effect on sleep, future research should consider ecological momentary assessment to examine how exposure and outcomes (co)vary within-persons, over time, and across contexts. Trial registration Netherlands Trial Register trial number NL56022.041.16.

医院夜班工作人员的睡眠质量、睡眠时间和睡眠障碍:一项前瞻性队列研究。
目的:本研究旨在评估医院夜班工人(i)睡眠质量、睡眠时间和睡眠障碍的重叠程度,以及(ii)社会人口因素、生活方式因素和工作特点与睡眠成分之间的关联:数据来自参加 Klokwerk + 研究的 467 名医院夜班工人,这是一项前瞻性队列研究,有两种测量方法。睡眠质量由匹兹堡睡眠质量指数测量,睡眠时间和睡眠障碍由医学结果研究睡眠量表测量。三种睡眠测量方法之间的重叠用维恩图表示,并计算重叠的比例。使用泊松回归模型估算了自变量(社会人口学因素、生活方式因素和工作特征)与三种睡眠结果之间的关系:结果:约 50%的医院夜班工人至少有一种睡眠不良后果。其中,36.8%的夜班工人的睡眠质量明显不佳,而大多数夜班工人(63.1%)的睡眠质量仅有一项不佳。曾经吸烟与睡眠质量差有明显关系。大多数自变量与睡眠质量差没有关联:我们的研究结果表明,睡眠质量、睡眠时间和睡眠障碍是不同的实体,应分别进行研究。生活方式因素和工作特点一般与睡眠质量差无关。由于这些因素会对睡眠产生剧烈影响,因此未来的研究应考虑生态学瞬间评估,以检查暴露和结果如何在人体内、随时间和环境而变化。试验注册 荷兰试验注册试验编号 NL56022.041.16。

期刊介绍: International Archives of Occupational and Environmental Health publishes Editorials, Review Articles, Original Articles, and Letters to the Editor. It welcomes any manuscripts dealing with occupational or ambient environmental problems, with a special interest in research at the interface of occupational health and clinical medicine. The scope ranges from Biological Monitoring to Dermatology, from Fibers and Dust to Human Toxicology, from Nanomaterials and Ultra-fine Dust to Night- and Shift Work, from Psycho-mental Distress and Burnout to Vibrations. A complete list of topics can be found on the right-hand side under For authors and editors. In addition, all papers should be based on present-day standards and relate to: -Clinical and epidemiological studies on morbidity and mortality -Clinical epidemiological studies on the parameters relevant to the estimation of health risks -Human experimental studies on environmental health effects. Animal experiments are only acceptable if relevant to pathogenic aspects. -Methods for studying the topics mentioned above.
