The current study aimed to investigate the differences in sleep reactivity and sleep effort differs among late night shift workers (LSWs) and non-late night shift workers (non-LSWs), and non-shift workers (non-SWs).
In total, 6,023 participants (1,613 non-SWs, 3,339 LSWs, and 1,071 non-LSWs) were recruited. Non-SWs was defined as those who works at fixed schedules during standard daylight. LSWs was defined as who work late night hours (10 PM-6 AM), while non-LSWs was SWs who did not work during late night. All completed the Ford Insomnia Response to Stress Test (FIRST), the Glasgow Sleep Effort Scale (GSES), the Pittsburgh Sleep Quality Index (PSQI), the Epworth Sleepiness Scale (ESS), the Insomnia Severity Index (ISI), and the short-term Center for Epidemiologic Studies-Depression scale (CES-D) through online survey.
LSWs and non-LSWs reported higher FIRST, GSES scores than non-SWs. In addition, LSWs reported higher FIRST, GSES scores than non-LSWs. FIRST scores were correlated with CES-D, PSQI, ISI, and ESS for LSWs, non-LSWs, and non-SWs alike. GSES scores were also correlated with CES-D, PSQI, ISI, and ESS for LSWs, non-LSWs, and non-SWs alike.
SWs showed higher sleep reactivity and sleep effort than non-SWs. LSWs had higher sleep reactivity and sleep effort than non-LSWs, and these variables are associated with insomnia, daytime sleepiness, and depressive symptoms. Our findings suggests that late night schedule, may increase sleep reactivity and sleep effort, which are associated with sleep and mood disturbances.
本研究旨在调查深夜轮班工作者（LSWs）、非深夜轮班工作者（非LSWs）和非轮班工作者（非SWs）在睡眠反应性和睡眠努力程度上的差异。
总共招募了6023名参与者（1613名非SWs、3339名LSWs和1071名非LSWs）。非SWs被定义为在标准白天时间按固定时间表工作的人。LSWs被定义为在深夜（晚上10点至早上6点）工作的人，而非LSWs是指不在深夜工作的SWs。所有参与者均通过在线调查完成了福特失眠应激反应测试（FIRST）、格拉斯哥睡眠努力量表（GSES）、匹兹堡睡眠质量指数（PSQI）、爱泼华嗜睡量表（ESS）、失眠严重程度指数（ISI）以及短期流行病学研究中心抑郁量表（CES-D）。
LSWs和非LSWs报告的FIRST、GSES得分高于非SWs。此外，LSWs报告的FIRST、GSES得分高于非LSWs。对于LSWs、非LSWs和非SWs而言，FIRST得分均与CES-D、PSQI、ISI和ESS相关。GSES得分也与LSWs、非LSWs和非SWs的CES-D、PSQI、ISI和ESS相关。
SWs的睡眠反应性和睡眠努力程度高于非SWs。LSWs的睡眠反应性和睡眠努力程度高于非LSWs，并且这些变量与失眠、日间嗜睡和抑郁症状相关。我们的研究结果表明，深夜工作时间表可能会增加睡眠反应性和睡眠努力程度，这与睡眠和情绪障碍有关。
