Objective: The present study examined if caregivers’ long work hours or shift work are related to children’s sleep duration through the disruption of bedtime routines. Method: Work hours and schedules, bedtime routines and sleep (actigraph assessments) were examined in a sample of 250 caregivers and their preschool children. Results: Results revealed that consistent bedtime routines mediated the relationship between caregiver’s work and children’s sleep, such that longer hours and shift work predicted fewer routines that, in turn, predicted less child sleep. Conclusion: These results point to the crucial role of bedtime routines as a promising point of intervention for working parents. While caregivers may not be able to change their work hours or schedules, they can create more stable and consistent bedtime routines to mitigate the negative effects of their work on children’s sleep.

父母不规范工作与孩子睡眠：就寝时间的中介作用


目的：本研究旨在探讨看护者的长时间工作或轮班工作是否通过扰乱就寝时间与儿童的睡眠时间相关。方法：对 250 名护理人员及其学龄前儿童的工作时间和日程安排、就寝时间和睡眠（活动记录仪评估）进行了检查。结果：结果显示，一致的就寝时间调节了看护者的工作与儿童睡眠之间的关系，因此较长的工作时间和轮班工作预示着较少的作息时间，反过来又预示着儿童睡眠的减少。结论：这些结果表明就寝时间作为对职业父母来说有希望的干预点的关键作用。虽然看护者可能无法改变他们的工作时间或时间表，但他们可以制定更稳定和一致的就寝时间，以减轻工作对儿童睡眠的负面影响。
