The booming online shopping industry has accelerated the growth of logistic services, often subjecting workers to irregular schedules. This study aims to examine the association between night-shift work and health-related quality of life among logistics workers, with a special focus on the mediating role of sleep characteristics. A survey was conducted among logistics workers across China, who filled out an online questionnaire. The questionnaire collected information about shift work, sleep characteristics, health-related quality of life, various sociodemographic factors, and specific job categories. The Insomnia Severity Index measured sleep quality, while the 12-Item Short Form Health Survey assessed health-related quality of life, including the physical and mental components. Linear regression analysis and structural equation modeling were used to examine the proposed associations and conduct mediation analysis, respectively. Out of the 484 respondents, 352 (72.7%) worked night shifts. These workers were predominantly males, smokers, alcohol users, less educated, and those with longer working hours involved in goods transportation and distribution. Our results showed a considerable trend of declining general health when transitioning from day to night shifts. There was a negative association between the frequency of night shift work and physical health. Specifically, those who worked more than 12 night shifts a month reported poorer health compared to those working permanent daytime, after adjustments for confounding variables. Sleep quality emerged as a significant mediator in this relationship. Our findings underscore the need to prioritize improving sleep quality to enhance the health and well-being of logistics workers.
蓬勃发展的在线购物行业加速了物流服务的增长，这常常使工人的工作时间不规律。本研究旨在探讨物流工人夜班工作与健康相关生活质量之间的关联，特别关注睡眠特征的中介作用。在中国各地的物流工人中进行了一项调查，他们填写了一份在线问卷。问卷收集了有关轮班工作、睡眠特征、健康相关生活质量、各种社会人口学因素以及具体工作类别的信息。失眠严重程度指数用于衡量睡眠质量，而简明健康调查问卷评估健康相关生活质量，包括身体和心理方面。分别使用线性回归分析和结构方程模型来检验所提出的关联并进行中介分析。在484名受访者中，352人（72.7%）上夜班。这些工人主要是男性、吸烟者、饮酒者、受教育程度较低，以及从事货物运输和配送且工作时间较长的人。我们的结果显示，从白班转为夜班时，总体健康状况有相当明显的下降趋势。夜班工作频率与身体健康之间存在负相关。具体而言，在对混杂变量进行调整后，每月上超过12个夜班的人比长期上白班的人健康状况更差。睡眠质量在这种关系中是一个重要的中介因素。我们的研究结果强调了优先改善睡眠质量以提高物流工人健康和福祉的必要性。
