Abstract

Purpose: Quality sleep is vital for good health. Although it is known that workhours affect sleep quality, it is not known at what point workhours begin to compromise sleep. Few studies consider workhours in the 'other job' (domestic and care work) or address reverse causality between sleep quality and how long people work. This study aimed to estimate the point at which weekly workhours harm sleep, among employed Australians aged 25-64.

Methods: Using Australian data (19,453 observations from 9,826 adults assessed 2013, 2017, and 2021), a maximum likelihood instrumental variable approach modelled the influence of domestic and care hours on workhours and then the effect of workhours on sleep. We tested for a non-linear pattern and a potential tipping point or limit at which sleep quality declines. Sleep quality scores were constructed from sleep duration (hours), quality rating, medications, and problems with onset.

Results: We estimated a population tipping point of 42 workhours per week, beyond which sleep quality deteriorated. Notably, women demonstrated a lower tipping point (36 h) beyond which their sleep quality deteriorated compared to men (47 h), likely linked to their greater care and domestic workhours in the home.

Conclusions: Our methods allowed us to specify the point at which weekly workhours were optimal for sleep quality and the point beyond which they become harmful. By considering unequal hours worked in care and domestic work, we were able to identify distinct gender differences in this relationship.

工作时间对睡眠质量的影响:非线性和性别差异。
目的优质睡眠对身体健康至关重要。尽管人们知道工作时间会影响睡眠质量,但却不知道工作时间从什么时候开始影响睡眠质量。很少有研究考虑到 "其他工作"(家务和护理工作)的工作时间,也很少有研究探讨睡眠质量与工作时间之间的反向因果关系。本研究旨在估算 25-64 岁澳大利亚在职者每周工作时间对睡眠的危害程度:利用澳大利亚的数据(9826 名成年人的 19453 个观测值,分别评估了 2013 年、2017 年和 2021 年的数据),采用最大似然工具变量法模拟了家务和护理时间对工作时间的影响,然后模拟了工作时间对睡眠的影响。我们测试了非线性模式和睡眠质量下降的潜在临界点或极限。睡眠质量评分由睡眠时间(小时)、质量评分、药物和发病问题构成:我们估计,每周 42 个工作小时是一个人口临界点,超过这个临界点,睡眠质量就会下降。值得注意的是,与男性(47 小时)相比,女性睡眠质量恶化的临界点(36 小时)较低,这可能与她们在家庭中更多的护理和家务劳动时间有关:我们的方法使我们能够明确每周工作时间对睡眠质量最有利的时间点,以及超过该时间点后对睡眠质量有害的时间点。通过考虑护理和家务工作中的不平等工时,我们能够发现这种关系中的明显性别差异。

期刊介绍: Archives of Women’s Mental Health is the official journal of the International Association for Women''s Mental Health, Marcé Society and the North American Society for Psychosocial Obstetrics and Gynecology (NASPOG). The exchange of knowledge between psychiatrists and obstetrician-gynecologists is one of the major aims of the journal. Its international scope includes psychodynamics, social and biological aspects of all psychiatric and psychosomatic disorders in women. The editors especially welcome interdisciplinary studies, focussing on the interface between psychiatry, psychosomatics, obstetrics and gynecology. Archives of Women’s Mental Health publishes rigorously reviewed research papers, short communications, case reports, review articles, invited editorials, historical perspectives, book reviews, letters to the editor, as well as conference abstracts. Only contributions written in English will be accepted. The journal assists clinicians, teachers and researchers to incorporate knowledge of all aspects of women’s mental health into current and future clinical care and research.
