Abstract

Purpose: Many shift nurses experience poor sleep quality, and the effect on nurses' cognitive function remains unclear. The study aims to investigate sleep status and explore its association with cognitive function.

Methods: This descriptive cross-sectional study was conducted in a tertiary care hospital in Fujian, China between March and September 2022. By convenience sampling method, 588 shift nurses participated in this study. The Pittsburgh Sleep Quality Index (PSQI) and Bergen Shift Work Sleep Questionnaire (BSWSQ) were used to assess sleep quality, while the Chinese version of Ascertain Dementia-8 (AD-8) was used to evaluate cognitive function. A PSQI score ≤7 is classified as good sleep quality, and a score >7 indicates poor sleep quality. An AD-8 score≥ 2 is considered indicative of memory impairment. Multivariate logistic regression analysis was conducted to explore the association between sleep status and memory impairment.

Results: A total of 310 (52.6%) participants presented poor sleep quality. Among them, 52.2% of participants had day shift-related sleep problems, 45.9% had evening shift-related sleep problems, 61.9% had night shift-related sleep problems, and 15.0% reported rest-day/vacation-related sleep problems. The prevalence of poor sleep quality and each shift-related sleep problem in the memory impairment group were higher than in the normal memory group (P<0.05). Multivariate logistic regression analysis indicated that poor sleep quality (OR=2.073, 95% CI: 1.398~3.072), evening shift-related sleep problems (OR=1.707, 95% CI: 1.028~2.835), night shift-related sleep problems (OR=1.859, 95% CI:1.104~3.129), and rest-day/vacation-related sleep problems (OR=2.069, 95% CI:1.170~3.659) was significantly associated with memory impairment.

Conclusion: This study highlights the prevalence of poor sleep quality among clinical nurses and identifies poor sleep quality and shift-related sleep problems (excluding day shift) as risk factors for memory impairment. Nurse managers should prioritize sleep quality and focus on cognitive function to enhance nurses' occupational health.

中国轮班护士睡眠不足与记忆力减退之间的关系：一项横断面研究

目的：许多轮班护士的睡眠质量不佳，而睡眠质量对护士认知功能的影响尚不清楚。本研究旨在调查睡眠状况并探讨其与认知功能的关系：这项描述性横断面研究于 2022 年 3 月至 9 月在中国福建省的一家三级甲等医院进行。通过方便抽样法，588 名轮班护士参与了本研究。研究采用匹兹堡睡眠质量指数（PSQI）和卑尔根轮班工作睡眠问卷（BSWSQ）评估睡眠质量，采用中文版 "痴呆-8"（AD-8）评估认知功能。PSQI得分≤7分为睡眠质量良好，得分>7表示睡眠质量差。AD-8得分≥2分表示记忆力受损。我们进行了多变量逻辑回归分析，以探讨睡眠状况与记忆障碍之间的关联：共有 310 人（52.6%）睡眠质量不佳。其中，52.2%的参与者有与白班相关的睡眠问题，45.9%的参与者有与晚班相关的睡眠问题，61.9%的参与者有与夜班相关的睡眠问题，15.0%的参与者有与休息日/假期相关的睡眠问题。记忆力受损组中睡眠质量差和每种与轮班有关的睡眠问题的发生率都高于记忆力正常组（结论：本研究强调了睡眠质量差和每种与轮班有关的睡眠问题的发生率：这项研究强调了睡眠质量差在临床护士中的普遍性，并指出睡眠质量差和与轮班有关的睡眠问题（不包括白班）是导致记忆力受损的风险因素。护士管理者应优先考虑睡眠质量并关注认知功能，以提高护士的职业健康水平。

期刊介绍： Nature and Science of Sleep is an international, peer-reviewed, open access journal covering all aspects of sleep science and sleep medicine, including the neurophysiology and functions of sleep, the genetics of sleep, sleep and society, biological rhythms, dreaming, sleep disorders and therapy, and strategies to optimize healthy sleep. Specific topics covered in the journal include: The functions of sleep in humans and other animals Physiological and neurophysiological changes with sleep The genetics of sleep and sleep differences The neurotransmitters, receptors and pathways involved in controlling both sleep and wakefulness Behavioral and pharmacological interventions aimed at improving sleep, and improving wakefulness Sleep changes with development and with age Sleep and reproduction (e.g., changes across the menstrual cycle, with pregnancy and menopause) The science and nature of dreams Sleep disorders Impact of sleep and sleep disorders on health, daytime function and quality of life Sleep problems secondary to clinical disorders Interaction of society with sleep (e.g., consequences of shift work, occupational health, public health) The microbiome and sleep Chronotherapy Impact of circadian rhythms on sleep, physiology, cognition and health Mechanisms controlling circadian rhythms, centrally and peripherally Impact of circadian rhythm disruptions (including night shift work, jet lag and social jet lag) on sleep, physiology, cognition and health Behavioral and pharmacological interventions aimed at reducing adverse effects of circadian-related sleep disruption Assessment of technologies and biomarkers for measuring sleep and/or circadian rhythms Epigenetic markers of sleep or circadian disruption.
