Although commuting time is an extension of working hours, few studies have examined the relationship between commuting time and insomnia symptoms in relation to working time. Thus, this study investigated the relationship between commuting time and working time and their link to sleep disturbance.
This study included employees with ≥35 weekly working hours (n = 30,458) using data from the Sixth Korean Working Conditions Survey conducted in Korea between October 2020 and April 2021. The association between commuting time (≤60, 61-120, and >120 minutes) and insomnia symptoms based on working hours (35-40, 41-52, and >52 h/wk) or shift work was investigated using survey-weighted logistic regression analysis.
Long commuting time (>120 min/d) combined with >52 working hours/week (OR: 7.88, 95% CI: 2.51-24.71) or combined with 41-52 h/wk (OR: 3.64, 95% CI: 2.15-6.14) was associated with a higher risk of insomnia symptoms compared with the reference group (working hours: 35-40 h/wk; daily commuting time: ≤60 minutes), after controlling for sex, age, socioeconomic factors, and work-related factors. Among shift workers, those with daily commuting time ≤60 minutes (OR: 1.71, 95% CI: 1.39-2.09), 61-120 minutes (OR: 2.63, 95% CI: 1.21-5.74), and >120 minutes (OR: 5.16, 95% CI: 2.14-12.44) had higher odds of insomnia symptoms than nonshift workers with ≤60 minutes daily commuting time.
Long working hours and shift work are associated with greater risk of insomnia symptoms.
尽管通勤时间是工作时间的延伸，但很少有研究探讨通勤时间与失眠症状之间与工作时间相关的关系。因此，本研究调查了通勤时间与工作时间之间的关系及其与睡眠障碍的联系。
本研究纳入了每周工作时长≥35小时的员工（n = 30458），使用的是2020年10月至2021年4月在韩国进行的第六次韩国工作条件调查的数据。基于工作时长（35 - 40、41 - 52和>52小时/周）或轮班工作情况，采用调查加权逻辑回归分析，研究通勤时间（≤60、61 - 120和>120分钟）与失眠症状之间的关联。
在控制了性别、年龄、社会经济因素和工作相关因素后，与参照组（工作时长：35 - 40小时/周；每日通勤时间：≤60分钟）相比，通勤时间长（>120分钟/天）且每周工作时长>52小时（比值比：7.88，95%置信区间：2.51 - 24.71）或与每周工作41 - 52小时（比值比：3.64，95%置信区间：2.15 - 6.14）相结合，与失眠症状风险较高相关。在轮班工人中，每日通勤时间≤60分钟（比值比：1.71，95%置信区间：1.39 - 2.09）、61 - 120分钟（比值比：2.63，95%置信区间：1.21 - 5.74）和>120分钟（比值比：5.16，95%置信区间：2.14 - 12.44）的人比每日通勤时间≤60分钟的非轮班工人患失眠症状的几率更高。
长时间工作和轮班工作与更高的失眠症状风险相关。
