Although many studies have examined the association between shift work and depression or insomnia, few studies have examined the relationship between quick return (QR) to work and depressive symptoms, regardless of shift work. Thus, in this study, we aimed to assess the association between depressive symptoms (DS)/sleep disturbances (SDs) and QR.
Data from the 6 Korean Working Conditions Survey (2020) were used for this study. Paid workers aged between 20 and 65 years were included. DS were defined using the World Health Organization Well-Being Index (WHO-5) with a cut-off 50, and SD was defined as the occurrence of the following symptoms several times per month: difficulty in falling asleep, waking up in the middle of the night, or feeling tired even after waking up. QR was defined as "at least one case where the working interval between leaving work and the next day's work was < 11 h in the past month." Multivariable logistic regression was performed to estimate the adjusted odd ratios (aORs) and 95% confidence intervals (CIs). Mediation analysis was conducted to examine whether SD was a significant mediator in the association between QR and DS.
Among the 27,554 participants, DS occurred in 8,277 patients, while SD occurred in 6,264 patients. The aORs (95% CIs) of DS and SD by QR were 2.01 (1.78-2.27) and 3.24 (2.87-3.66), respectively, after adjusting for age, gender, income, education, working hours, job status, working duration, region, shift work, and occupation. SD was a significant mediator in the association between QR and DS.
QR is significantly associated with DS or SD regardless of demographic factors and the working environment. The significant relationship between QR and DS may be mediated by SD.
尽管许多研究已经考察了轮班工作与抑郁或失眠之间的关系，但很少有研究考察快速返回（QR）工作与抑郁症状之间的关系，而不论轮班工作如何。因此，在这项研究中，我们旨在评估抑郁症状（DS）/睡眠障碍（SD）与 QR 之间的关系。
本研究使用了 2020 年韩国工作条件调查（6 次）的数据。纳入年龄在 20 至 65 岁之间的有酬工人。DS 使用世界卫生组织幸福感指数（WHO-5）定义，截断值为 50；SD 定义为每月出现以下症状几次：入睡困难、半夜醒来或醒来后仍感到疲倦。QR 定义为“在过去一个月中，至少有一次离开工作和第二天工作之间的工作间隔<11 小时”。使用多变量逻辑回归来估计调整后的优势比（aOR）和 95%置信区间（CI）。进行中介分析以检验 SD 是否是 QR 和 DS 之间关联的重要中介因素。
在 27554 名参与者中，DS 发生在 8277 名患者中，而 SD 发生在 6264 名患者中。调整年龄、性别、收入、教育程度、工作时间、工作状态、工作时间、地区、轮班工作和职业后，QR 与 DS 和 SD 的 aOR（95%CI）分别为 2.01（1.78-2.27）和 3.24（2.87-3.66）。SD 是 QR 和 DS 之间关联的重要中介因素。
QR 与 DS 或 SD 显著相关，无论人口统计学因素和工作环境如何。QR 与 DS 之间的显著关系可能是由 SD 介导的。
