Obstructive sleep apnea (OSA) and insomnia could accelerate biological aging through pathways including oxidative stress and systemic inflammation. This systematic review aimed to determine the association of sleep disorders with circulating markers of biological aging. We searched MEDLINE, Embase, CINAHL, Cochrane, PsycINFO from inception to October 2024. Eligibility criteria included full manuscript English studies on adult humans examining OSA or insomnia and circulating markers of aging. Of the 1839 deduplicated records screened, 49 full-text studies were eligible for inclusion. Included studies ranged from poor to good quality and assessed telomere length (TL), DNA methylation clocks (epigenetics), mitochondrial alterations, sirtuin levels and activity, autophagy protein levels, and klotho gene expression. Telomeres were the most extensively studied marker, with our findings showing a significant association between TL and OSA, based on both unadjusted and adjusted values (SMD = -0.451, 95% CI: 0.688 to -0.215, p = 0.0026 and SMD = -3.01, 95% CI: 4.98 to -1.04, p = 0.033, respectively). Most studies linked insomnia and poor sleep quality to shorter TL. Although evidence for other aging biomarkers was more limited, the published literature supports the role of OSA and insomnia in accelerating biological aging, especially for telomere length.

The consequences of untreated obstructive sleep apnea (OSA) on health are well established. OSA alterations to sleep microarchitecture include a reduction in sleep spindles during NREM sleep, a neurophysiological biomarker that reflects sleep stability, cognitive function and brain health. However, the effects of OSA treatment on reversing sleep spindle abnormalities remains unclear. This systematic review evaluated the effect of continuous positive airway pressure (CPAP) treatment on spindles during polysomnography in adults diagnosed with OSA. We identified five papers meeting inclusion criteria with a total of 202 participants. Two studies analyzed spindle density after 6 months of CPAP use and three analyzed spindle activity during CPAP titration. Three studies used automatic spindle detection methods. Meta-analysis showed a significant increase in spindle density after CPAP use (mean difference = 1.16 spindles/min, 95 % CI [0.27, 2.04], p = 0.010). However, heterogeneity was high due to variability in study designs, sample sizes, and methodological factors. In conclusion, CPAP treatment increased spindle density in adult patients with OSA. Future research should aim to standardize spindle detection protocols and incorporate both objective and subjective measures. Establishing whether spindle changes mediate the functional recovery seen with CPAP will be essential to investigate their potential clinical utility.
未经治疗的阻塞性睡眠呼吸暂停(OSA)对健康的影响是众所周知的。OSA对睡眠微结构的改变包括NREM睡眠期间睡眠纺锤波的减少,这是一种反映睡眠稳定性、认知功能和大脑健康的神经生理生物标志物。然而,阻塞性睡眠呼吸暂停治疗对逆转睡眠纺锤体异常的影响尚不清楚。本系统综述评估了持续气道正压(CPAP)治疗对诊断为OSA的成人多导睡眠图中纺锤体的影响。我们确定了5篇符合纳入标准的论文,共有202名受试者。两项研究分析了使用CPAP 6个月后的纺锤体密度,三项研究分析了CPAP滴定期间的纺锤体活动。三项研究采用自动主轴检测方法。meta分析显示,使用CPAP后纺锤波密度显著增加(平均差异= 1.16纺锤波/分钟,95% CI [0.27, 2.04], p = 0.010)。然而,由于研究设计、样本量和方法学因素的可变性,异质性很高。综上所述,CPAP治疗增加了OSA成人患者的纺锤体密度。未来的研究应旨在标准化主轴检测协议,并结合客观和主观的措施。确定纺锤体变化是否介导CPAP所见的功能恢复,对于研究其潜在的临床应用至关重要。

Background
Given the increased use of network analysis in sleep studies, this systematic review and statistical evaluation aimed to aggregate network studies to identify the most central symptoms in composite network models of sleep-related symptoms.
Methods
A systematic search of cross-sectional network studies focused exclusively on sleep within community or clinical samples was conducted across PubMed, Web of Science (WOS), PsycINFO, and EMBASE databases up to March 5, 2025. Studies were categorized by topic and measurement instruments. Statistical evaluations extracted the most central symptoms across network models.
Results
The review included 23 studies of 84,510 participants and 29 network models. Explored topics included insomnia/sleep disturbances, sleep quality, sleep attitudes and behaviors, daytime function, and dream content. Regarding main analyses, key central symptoms in network models of insomnia were “Difficulty staying asleep” [median rank:1.5, Interquartile range (IQR): 1–2], “Distress caused by the sleep difficulties” (median rank:2, IQR: 2–3) and “Interference with daytime functioning” (median rank:3.5, IQR: 2.25–4). For sleep quality, “Subjective sleep quality” (median rank:1, IQR: 1-1), “Daytime dysfunction” (median rank:3, IQR: 2–5.25) and “Sleep disturbance” (median rank:3.5, IQR: 2–4.5) were the most central experiences.
Conclusions
Identified central symptoms offer plausible targets for intervention across populations and guide future research directions.

According to the two process model, sleep timing and duration are determined by the interaction of process S (the sleep homeostat) and process C (the circadian drive for alertness). Although originally invoked to account only for sleep inertia effects (post-awakening performance deficits), there is evidence that process W is also active during sleep, and that it serves a sleep-preserving function that is partly independent of processes S and C. This suggests that initiation of the natural, spontaneous awakening process at the end of an adequately restorative sleep period is not passively triggered by the combined effects of a reduced process S and an ascendant process C alone – it also requires that a process W-mediated barrier against awakening be breached. It is hypothesized that one function of REM sleep is to periodically test the level of stimulation needed to breach this barrier, with the extent to which cortical reactivation occurs during REM sleep reflecting the brain's level of sleep satiation. It is further hypothesized that this REM-elicited neuronal reactivation information is processed (possibly in the medial prefrontal cortex) to determine readiness for awakening, and this information is communicated (e.g., via the lateral hypothalamus) to the REM/NREM and sleep/wake “flip-flop” switches that either initiate awakening or the return to NREM sleep, as appropriate.

Early childhood insomnia (ECI) affects 20-30 % of children aged 6-36 months, making it the most common sleep disturbance in this age group. Current interventions often focus on independent sleep through extinction-based behavioral methods, with less emphasis on broader socioecological influences such as caregiving quality and feeding practices. This paper introduces a conceptual model to reframe ECI interventions using the World Health Organization endorsed Nurturing care framework (NCF), which includes five components: good health, adequate nutrition, safety and security, responsive caregiving and opportunities for learning. Sleep is essential for health, and early childhood represent a critical window for shaping lifelong sleep patterns. Breastfeeding helps integration of all five components while responsive caregiving, supports the other four components. Sensory-motor nourishment fosters a sense of safety and early learning opportunities promote self-regulation. The model outlines actionable strategies under each NCF components, offering guidance for researchers and supporting adaptation across diverse settings, viewing sleep health as part of a broader caregiver ecosystem rather than isolated behavioral problem.

Background: This systematic review and Bayesian meta-analysis examined determinants of exercise effects on subjective sleep quality.
Methods: We searched PubMed, Embase, Cochrane Library, Web of Science, Scopus and CINAHL from inception to August 2025 for randomised controlled trials in adults (≥18 years) comparing exercise with non-exercise controls. Two reviewers independently assessed risk of bias (RoB 2). Bayesian multilevel models, MetaForest and structural equation modelling estimated pooled effects and moderators, expressed as standardised mean differences (Hedges' g).
Results: Two hundred trials (n = 23,523) were included. Compared with active controls, qigong, walking and high-intensity interval training showed the largest benefits. In 20 trials reporting objective sleep efficiency, exercise produced a small but significant improvement, consistent with subjective outcomes. Baseline sleep quality (assessed with Pittsburgh Sleep Quality Index) and population type were the main determinants of response. Populations with poorer baseline sleep quality were much more likely to achieve a clinically important improvement than good sleepers. Intervention duration showed a U-shaped association with benefit, peaking at 25 weeks. Certainty of evidence was very low.
Conclusion: Exercise improves subjective sleep quality in a benefit-on-demand pattern, supporting prioritisation of approximately 25-week programmes for adults with moderate-to-severe sleep problems while acknowledging very low certainty.
背景:本系统综述和贝叶斯荟萃分析考察了运动对主观睡眠质量影响的决定因素。方法:我们检索PubMed, Embase, Cochrane Library, Web of Science, Scopus和CINAHL,从成立到2025年8月,在成人(≥18岁)中比较运动和非运动对照组的随机对照试验。两名审稿人独立评估偏倚风险(RoB 2)。贝叶斯多层模型、MetaForest和结构方程模型估计了汇总效应和调节因子,表示为标准化平均差异(Hedges’g)。结果:纳入200项试验(n = 23,523)。与主动控制组相比,气功、散步和高强度间歇训练显示出最大的益处。在20项报告客观睡眠效率的试验中,锻炼产生了微小但显著的改善,与主观结果一致。基线睡眠质量(用匹兹堡睡眠质量指数评估)和人群类型是反应的主要决定因素。与睡眠质量良好的人相比,基线睡眠质量较差的人更有可能获得临床重要的改善。干预持续时间与获益呈u型关系,在25周时达到峰值。证据的确定性非常低。结论:运动以一种按需受益的模式改善了主观睡眠质量,在承认非常低的确定性的情况下,支持为中度至重度睡眠问题的成年人优先安排大约25周的计划。
