摘要

目的:将失眠的症状定义为入睡困难、保持睡眠困难和早醒。非恢复性睡眠(NRS)虽然也是失眠的一种症状,但与其他失眠症状相比,它与客观指标的关联明显更大。然而,NRS和加班时间之间的联系却鲜为人知。方法:对26144名30 ~ 59岁的日本上班族进行了一年的体检。通过计算机辅助医疗访谈收集NRS状态和生活方式。研究对象被问及是否存在NRS以及他们最近两到三个月的生活方式。研究对象被问及他们每月的睡眠时间和平均加班时间(结果:随着加班时间的增加,NRS受试者的比例呈逐步增加的趋势。以NRS为客观变量进行logistic回归分析。多变量分析表明,加班时间(OR, 1.13;95% ci 1.10-1.17;结论:对于上班族来说,长时间的加班工作增加了任何睡眠时间的NRS患病率。

Overtime work is related to nonrestorative sleep independently of short sleep time among a Japanese occupational population.

Overtime work is related to nonrestorative sleep independently of short sleep time among a Japanese occupational population.

Objective: The symptoms of insomnia are defined as difficulty falling asleep, difficulty staying asleep, and early awakening. Although also a symptom of insomnia, nonrestorative sleep (NRS) is clearly more associated with objective indices than other insomnia symptoms. However, the link between NRS and overtime work duration is poorly understood.

Methods: The results of a single year's medical examinations were investigated for 26,144 Japanese office workers who were 30 to 59 years old. NRS status and lifestyle were collected through a computer-assisted medical interview. The subjects were asked about the presence or absence of NRS and their lifestyles in the most recent two to three months. The subjects were asked about their sleep times and average overtime durations per month (< 20 h/month, ≥ 20 but < 40 h/month, ≥ 40 but < 60 h/month, and ≥ 60 h/month). The relationships between NRS and overtime work duration adjusted for sleep time were also analyzed.

Results: The proportion of subjects with NRS showed a stepwise increase as overtime work hours increased. A logistic regression analysis was performed using NRS as an objective variable. The multivariate analysis demonstrated that overtime work duration (OR, 1.13; 95% CI 1.10-1.17; P < 0.001; per one-category increase) was an independent determinant of NRS.

Conclusion: For office workers, long hours of overtime work increased the NRS prevalence at any sleep duration.

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.
