Abstract

Abstract: The regularity of sleep/wake patterns across multiple days is emerging as an important determinant of health. However, the association between sleep regularity and health outcomes in the aging population is not well understood. The current systematic review identified 22 publications that examined the relationship between sleep regularity and selected health outcomes: cardiovascular risk, cognitive impairment, and mortality. All studies were published after 2010, reflecting a growing research interest in daily sleep regularity. Low sleep regularity was consistently associated with higher cardiovascular risk and elevated risk of all-cause mortality. Results on cognitive impairment are mixed, with inconsistency likely attributed to small sample sizes and differences in sleep regularity assessment. Overall, regularity in sleep carries important information about health and should be included in future studies that collect daily sleep measures. Gaps in literature and methodological shortcomings are discussed.

Keywords: sleep regularity, Aging, cardiovascular health, cognitive impairment, mortality

睡眠规律对老年人心血管健康和认知障碍的新重要性：文献综述

摘要：多日睡眠/觉醒模式的规律性正在成为健康的一个重要决定因素。然而，人们对睡眠规律性与老龄人口健康结果之间的关系还不甚了解。本次系统综述共发现了 22 篇研究睡眠规律性与特定健康结果（心血管风险、认知障碍和死亡率）之间关系的文章。所有研究均发表于 2010 年之后，这反映出人们对日常睡眠规律性的研究兴趣日益浓厚。低睡眠规律性始终与较高的心血管风险和全因死亡风险相关。关于认知障碍的研究结果不一，不一致的原因可能是样本量小和睡眠规律性评估的差异。总之，睡眠规律性蕴含着重要的健康信息，应纳入今后收集日常睡眠测量数据的研究中。本文讨论了文献中的空白和方法上的不足。关键词：睡眠规律性；老龄化；心血管健康；认知障碍；死亡率

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.
