Shift work disrupts circadian rhythms, causing sleep and mood problems. Sleep reactivity-the sensitivity of sleep to stress-may affect how shift workers cope with these disruptions. This study investigated the relationship between sleep reactivity and shift work, exploring associations between sleep reactivity and sleep disturbance, mood symptoms, and quality of life in shift workers.
In a cross-sectional design, 132 participants (79 shift workers and 53 controls) were assessed using the Ford Insomnia Response to Stress Test (FIRST), Insomnia Severity Index (ISI), Pittsburgh Sleep Quality Index (PSQI), Epworth Sleepiness Scale (ESS), Beck Depression Inventory (BDI), Beck Anxiety Inventory (BAI), and World Health Organization Quality of Life (WHOQOL). We compared the self-reported measurements between shift workers and controls. Two-way ANOVA was performed to explore the interaction effects between shift work and sleep reactivity on sleep, mood parameters, and quality of life. Multiple linear regression analysis was conducted to identify factors associated with sleep, mood, and quality of life among shift workers.
Shift workers scored higher on ISI and BDI compared to controls. Two-way ANOVA revealed an interaction effect between shift work and sleep reactivity on WHOQOL. Regression analysis indicated that high sleep reactivity was associated with higher ISI, BDI, BAI, and lower WHOQOL among shift workers.
Sleep reactivity significantly affected shift worker's quality of life. Our findings indicate that high sleep reactivity in shift workers was associated with increased sleep disturbance, mood problems, and decreased quality of life, implying that sleep reactivity may predict shift work tolerance.
轮班工作会扰乱昼夜节律，导致睡眠和情绪问题。睡眠反应性——睡眠对应激的敏感程度——可能会影响轮班工作者应对这些干扰的方式。本研究调查了睡眠反应性与轮班工作之间的关系，探讨了睡眠反应性与轮班工作者的睡眠障碍、情绪症状及生活质量之间的关联。
采用横断面设计，使用福特失眠应激反应测试（FIRST）、失眠严重程度指数（ISI）、匹兹堡睡眠质量指数（PSQI）、爱泼华嗜睡量表（ESS）、贝克抑郁量表（BDI）、贝克焦虑量表（BAI）和世界卫生组织生活质量量表（WHOQOL）对132名参与者（79名轮班工作者和53名对照组）进行评估。我们比较了轮班工作者和对照组的自我报告测量结果。进行双向方差分析以探讨轮班工作和睡眠反应性对睡眠、情绪参数和生活质量的交互作用。进行多元线性回归分析以确定轮班工作者中与睡眠、情绪和生活质量相关的因素。
与对照组相比，轮班工作者在ISI和BDI上得分更高。双向方差分析显示轮班工作和睡眠反应性对WHOQOL有交互作用。回归分析表明，高睡眠反应性与轮班工作者中较高的ISI、BDI、BAI以及较低的WHOQOL相关。
睡眠反应性显著影响轮班工作者的生活质量。我们的研究结果表明，轮班工作者的高睡眠反应性与睡眠障碍增加、情绪问题及生活质量下降相关，这意味着睡眠反应性可能预测轮班工作耐受性。
