Abstract

Objective

The aim of this study is to estimate the association between night work and health-related quality of life (HRQoL) among French workers. The association between cumulative duration of night work and HRQoL was also investigated.

Methods

Three career-long night work exposure groups were defined at inclusion in the CONSTANCES cohort: permanent night workers, rotating night workers and former night workers. Day workers with no experience of night work were the reference group. HRQoL was assessed using the Short Form Health Survey (SF-12), in particular the physical component summary (PCS) and mental component summary (MCS) scores, with a higher score indicating better HRQoL. Several linear regression models were built to test the association between night work exposure and HRQoL. The relationship between cumulative duration of night work and HRQoL scores was analyzed using generalised additive models.

Results

The sample consisted of 10,372 participants. Former night workers had a significantly lower PCS score than day workers (β [95% CI]: − 1.09 [− 1.73; − 0.45], p = 0.001), whereas permanent night workers had a significantly higher MCS score (β [95% CI]: 1.19 [0.009; 2.36], p = 0.048). A significant decrease in PCS score from 5 to 20 years of cumulative night work was observed among former night workers.

Conclusions

Former night workers had poorer physical HRQoL in contrast to permanent and rotating night workers who had similar or even better HRQoL than day workers, suggesting the well-known healthy worker survivor effect. Consequently, both current and former night workers require regular and specific follow-up focused on the physical components of their health.

夜间工作与与健康有关的生活质量之间的关系：根据 CONSTANCES 队列中法国工人夜间工作的概况和累计持续时间进行的分析

本研究旨在估算法国工人夜间工作与健康相关生活质量（HRQoL）之间的关系。方法在纳入 CONSTANCES 队列时，定义了三个职业生涯中接触夜间工作的群体：长期夜间工作者、轮换夜间工作者和前夜间工作者。没有夜间工作经验的日间工作者为参照组。HRQoL 采用简表健康调查（SF-12）进行评估，特别是身体部分摘要（PCS）和精神部分摘要（MCS）得分，得分越高表明 HRQoL 越好。我们建立了几个线性回归模型来检验夜间工作暴露与 HRQoL 之间的关系。使用广义相加模型分析了累计夜间工作时间与 HRQoL 分数之间的关系。前夜班工人的 PCS 得分明显低于日班工人（β [95% CI]：- 1.09 [- 1.73; - 0.45]，p = 0.001），而长期夜班工人的 MCS 得分明显高于日班工人（β [95% CI]：1.19 [0.009; 2.36]，p = 0.048）。结论曾经从事夜间工作的人的身体健康与生活质量较差，而长期和轮换夜间工作的人的健康与生活质量与日间工作的人相似，甚至更好，这表明存在众所周知的健康工人幸存者效应。因此，无论是现在还是以前的夜班工人，都需要定期进行专门的跟踪调查，重点关注他们的身体健康情况。

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.
