Abstract Introduction Changes in cognitive performance during shiftwork due to fatigue and circadian misalignment are well-documented. However experimental evaluations of shiftwork schedules are often limited to basic tasks such as vigilance and attention. The current study evaluated several higher order cognitive functions such as memory and task switching during four simulated shiftwork schedules. Methods N=27 completed a 10-day laboratory shiftwork simulation. They were randomly assigned to one of four shiftwork conditions: Condition A, 4h-on/4h-off/8h-on/8h-off schedule; Condition B, 6h-on/6h-off schedule; Conditions C and D represented to different sections of a 4h-on/4h-on call/4h-off/4h-on/4h-on call/4h-off schedule. The Automated Neuropsychological Assessment Metrics (ANAM) was used to assess cognitive function. The tasks included in this analysis were Code Substitution (CDS/CDD), Pursuit Tracking (PUR), Matching to Sample (M2S), and Switching Task (SWT). Stability of performance during waking was compared between the conditions using Kruskal-Wallis tests. Results The analysis of cognitive performance tasks yielded mixed findings. Performance on all tasks was ranked from best to worst: Condition D (>Conditions A, B, C; all p < .05), Condition A (>Conditions B, C; p < .05 and p <.001, respectively), Condition B, Condition C. Regarding stability of higher order cognitive function across the waking day, Condition A exhibited the worst stability, and was the only condition whereby performance degraded across the wake period. Discussion These findings highlight the variability in cognitive capacities during different shiftwork schedules. It is important to examine higher order cognitive function, and other cognitive abilities during shiftwork, when evaluating different shiftwork schedules.
由于疲劳和昼夜节律失调,轮班工作期间认知表现的变化有充分的证据。然而,轮班工作时间表的实验评估往往仅限于基本任务,如警惕和注意力。目前的研究评估了在四种模拟轮班工作安排下的一些高级认知功能,如记忆和任务切换。方法27例完成10天实验室倒班模拟。他们被随机分配到四种轮班工作条件中的一种:条件A, 4小时开/4小时关/8小时开/8小时关;条件B, 6h-on/6h-off时间表;条件C和D表示4h-on/4h-on call/4h-off/4h-on/4h-on call/4h-off时间表的不同部分。采用自动神经心理评估量表(ANAM)评估认知功能。该分析包括代码替换(CDS/CDD)、追踪跟踪(PUR)、样本匹配(M2S)和切换任务(SWT)。使用Kruskal-Wallis测试比较醒时性能的稳定性。结果对认知表现任务的分析得出了不同的结果。所有任务的表现从好到坏排列:条件D (>条件A, B, C;所有p <.05),条件A (>条件B, C;p, lt;.05和p <关于高阶认知功能在清醒期间的稳定性,条件A表现出最差的稳定性,并且是唯一在清醒期间表现下降的条件。这些发现强调了在不同的轮班时间表中认知能力的可变性。在评估不同的轮班时间表时,检查轮班期间的高阶认知功能和其他认知能力是很重要的。

Abstract Introduction Addressing the urgent public health concern of sleep health among shiftworkers, our study examined the application and effectiveness of a tailored sleep intervention, the Sleepfit app. We assessed reach, effectiveness, adoption, and maintenance, while identifying potential implementation barriers across diverse shiftwork industries. Methods The two-phase study commenced with the Sleepfit app's optimisation, originally developed for day workers, by integrating sleep improvement strategies specifically for shiftworkers. The feasibility of large-scale implementation was then evaluated based on the RE-AIM framework, considering reach, effectiveness, adoption, implementation, and maintenance. The study involved existing shiftworkers (current sample, n=29; anticipated final sample n=90). Validated sleep health measures and RE-AIM metrics were used, with data analysed through a mixed-methods approach. Results Preliminary results indicate significant improvement in sleep satisfaction and reduction in insomnia severity, indicating the potential of the intervention in enhancing sleep outcomes. We also observed increased engagement with healthy sleep practices, demonstrated by a significant decrease in poor sleep behaviours. Interestingly, our preliminary findings propose specific benefits for younger shiftworkers who typically engage in problematic sleep practices. Preliminary data suggests 71% of shiftworkers engaged with the app at 2-weeks post intervention, with 23% continuing to use the app during long-term maintenance evaluation. As data collection is ongoing, a detailed analysis incorporating feasibility and all RE-AIM dimensions will be subsequently presented. Conclusion Preliminary findings suggest the Sleepfit app may serve as an effective sleep health intervention among shiftworkers, with further analyses needed to fully understand its feasibility and long-term adoption.
为了解决倒班工人睡眠健康这一紧迫的公共卫生问题,我们的研究检查了量身定制的睡眠干预应用程序Sleepfit的应用和有效性。我们评估了覆盖范围、有效性、采用和维护情况,同时确定了不同倒班行业的潜在实施障碍。该研究分为两个阶段,首先通过整合专门针对倒班工人的睡眠改善策略,对最初为白班工人开发的Sleepfit应用程序进行优化。然后基于RE-AIM框架评估大规模实施的可行性,考虑范围、有效性、采用、实施和维护。本研究涉及现有轮班工人(当前样本,n=29;预期最终样本n=90)。使用经过验证的睡眠健康测量和RE-AIM指标,并通过混合方法分析数据。结果初步结果显示,睡眠满意度显著提高,失眠严重程度降低,表明干预在改善睡眠结果方面具有潜力。我们还观察到健康睡眠习惯的增加,不良睡眠行为的显著减少证明了这一点。有趣的是,我们的初步研究结果为那些通常有问题的睡眠习惯的年轻轮班工人提供了具体的好处。初步数据显示,71%的轮班工人在干预后两周使用该应用程序,23%的人在长期维护评估期间继续使用该应用程序。由于数据收集正在进行中,随后将提出一份详细的分析,包括可行性和所有RE-AIM方面。初步研究结果表明,Sleepfit应用程序可以作为倒班工人有效的睡眠健康干预措施,但需要进一步分析以充分了解其可行性和长期采用。

Abstract Introduction Physical activity might be a nonphotic strategy which could improve cognitive performance for nightshift workers. Innate characteristics like circadian type may also influence individual performance. Thus, this study explores the relationship between circadian type and physical activity on cognition over consecutive nightshifts. Methods Thirty-two healthy adults (age M±SD: 24.3±4.6 years; 19 females) participated in a 7-day laboratory study, with 5 nightshifts (2200-0600). Participants were randomised into the Breaking up sitting (BUS; n=19) or Sedentary (SED; n=13) condition. Overnight, BUS participants completed 3-min bouts of light-intensity walking every 30-min, while SED participants remained seated. At 2200, 0000, 0200, 0400 and 0600, participants completed the 10-min Psychomotor Vigilance Task (mean RRT). Participants completed the 11-item revised Circadian Type Inventory (factor 1: rigid/flexible; factor 2: languid/vigorous), resulting in four-subgroups (rigid; n= 12, flexible; n= 11, and languid; n= 11, vigorous; n= 13). Participants may only be one type from either factor (i.e. rigid and vigorous). Results Linear mixed models showed a significant 3-way interaction between nightshift (1-5), condition (BUS, SED), and circadian type (rigid/flexible) for mean RRT (p=0.03), such that flexible types in the Breaking up sitting condition outperformed Sedentary flexible types and Breaking up sitting rigid types, with performance worse on the first nightshift. There were no significant interactions between nightshift, condition and circadian type (languid/vigorous). Discussion Breaking up sitting improved performance for flexible types over rigid types. These findings have significant implications for nightshift rostering, suggesting that incorporating breaking up sitting may optimise cognitive performance, and therefore work efficiency.
体育锻炼可能是一种非光性策略,可以改善夜班工作者的认知表现。生理节律类型等先天特征也可能影响个人表现。因此,本研究探讨了昼夜节律类型与连续夜班中身体活动对认知的关系。方法32例健康成人(年龄M±SD: 24.3±4.6岁;19名女性)参加了为期7天的实验室研究,5个夜班(2200-0600)。参与者被随机分配到分手坐(BUS;n=19)或久坐(SED;n = 13)条件。夜间,BUS组参与者每30分钟进行一次3分钟的轻强度步行,而SED组参与者则保持坐姿。在22:00,0200,0400和0600,参与者完成了10分钟的精神运动警戒任务(平均RRT)。参与者完成了11项修订的昼夜节律类型量表(因子1:刚性/柔性;因子2:懒散/活力),产生四个亚群(僵硬;N = 12,柔性;N = 11,倦怠;N = 11,旺盛;n = 13)。参与者只能是其中一种类型(即刚性和活力)。结果线性混合模型显示,夜班(1-5)、状态(BUS、SED)和昼夜节律类型(刚性/弹性)对平均RRT有显著的3向交互作用(p=0.03),即打破坐姿的灵活类型优于久坐的灵活类型和打破坐姿的刚性类型,其中第一个夜班的表现更差。夜班、病情和昼夜节律类型(懒散/旺盛)之间没有显著的相互作用。打破坐姿可以提高灵活型运动员的表现,而不是僵硬型运动员。这些发现对夜班排班有重要意义,表明休息可以优化认知能力,从而提高工作效率。

Abstract Introduction Young adulthood is a critical developmental period typified by heightened exposure to stress, and a tendency towards insufficient sleep. The relationship between sleep loss and stress may have lifelong health consequences. Currently, our understanding of this relationship in young adults is limited. Heart rate variability (HRV) is an important indicator of balance in the autonomic nervous system. We examined the association between sleep duration and HRV in response to cognitive stressors. Methods Seventy-six young adults (M=20.6±1.9, 72.4% female) who self-identified as short sleepers were recruited. Habitual sleep duration was monitored with actigraphy for two weeks. Participants subsequently underwent an in-lab experiment where their HRV was recorded during baseline, and during a cognitive stress condition involving the completion of computerised cognitive stress tasks. Participants also reported their habitual stress levels and sleep quality. Results Actigraphy assessment revealed that participants slept within the recommended sleep durations (M=7.8±0.7). The participants reported high habitual stress but normal sleep quality. Our moderation analysis indicates that shorter sleep duration was associated with elevated HRV during the cognitively demanding tasks. Conclusions Our findings demonstrate an association between sleep duration and HRV in the context of a cognitive stressor, indicating that sleep and stress are related in young adults. An unexpected negative relationship between sleep duration and HRV during the cognitively demanding tasks suggests complexity in this relationship; however, we should still look to reduce stress and improve sleep where we can in young adults. This association may be better understood via direct manipulation of sleep duration.
青年期是一个关键的发育时期,典型的特点是高度暴露于压力,并倾向于睡眠不足。睡眠不足和压力之间的关系可能会对健康产生终生的影响。目前,我们对这种关系在年轻人中的理解是有限的。心率变异性(HRV)是自主神经系统平衡的重要指标。我们研究了睡眠时间和心率波动之间的关系,以应对认知压力。方法招募自认短睡眠者76例(M=20.6±1.9,其中女性72.4%)。用活动记录仪监测习惯性睡眠持续时间两周。随后,参与者进行了一项实验室实验,记录了他们在基线和认知压力条件下(包括完成计算机化的认知压力任务)的HRV。参与者还报告了他们的习惯性压力水平和睡眠质量。结果活动描记评估显示,受试者睡眠时间均在推荐睡眠时间范围内(M=7.8±0.7)。参与者报告说,他们的习惯性压力很大,但睡眠质量正常。我们的适度分析表明,在认知要求较高的任务中,较短的睡眠时间与HRV升高有关。我们的研究结果表明,在认知压力源的背景下,睡眠时间和心率变异之间存在关联,这表明睡眠和压力在年轻人中是相关的。在认知要求较高的任务中,睡眠时间与心率变异性之间的负相关表明了这种关系的复杂性;然而,我们仍然应该尽可能减少压力,改善年轻人的睡眠。这种联系可以通过直接控制睡眠时间来更好地理解。

Abstract Introduction Most pediatric patients with obstructive sleep apnea (OSA) are known to be treated with adenotonsillectomy (AT). However, in some of them, positive airway pressure (PAP) can be used for underlying diseases or in case of AT failure. Thus, PAP adherence and compliance were compared in pediatric OSA to adult OSA. Methods A retrospective study was conducted on 17 children and 167 adults who had performed polysomnography (PSG) and were prescribed PAP and followed up for more than 3 months from July 2018 to January 2023. Adherence was defined as the percentage of patients continuing to use PAP after prescription and compliance was defined as an average of more than 4 hours per night usage of 70% of the monitoring days. Results There were 11 males (64.7%) in pediatric and 141 males (84.4%) in adult patients. The mean age was 8.0 years (6.50-12.50) in pediatric and 50.0 years (41.00-58.00) in adult patients. The mean apnea hypopnea index (AHI) (37.0 vs 50.7) and Lowest O2 saturation (79.4% vs 75.5%) did not show any differences in the 2 groups. Longest apnea showed considerable differences (25.9 sec vs 50.8 sec) (p=0.000). After 18 months of PAP usage, AHI dropped from 37.0 to 5.1 vs 50.7 to 2.6, adherence decreased from 94.1% to 41.2% vs 90.4% to 38.9% (p=0.944), compliance reduced from 64.7% to 28.9% vs 67.0% vs 29.3% (p=0.268) in pediatric and adults groups. Conclusions There were no significant differences in adherence and compliance with PAP in children compared to adults.
大多数患有阻塞性睡眠呼吸暂停(OSA)的儿童患者都接受腺扁桃体切除术(AT)治疗。然而,在其中一些病例中,气道正压通气(PAP)可用于潜在疾病或AT失败的情况。因此,比较了儿童OSA与成人OSA的PAP依从性和依从性。方法回顾性研究2018年7月至2023年1月行多导睡眠描记术(PSG)并给予PAP治疗的17名儿童和167名成人,随访时间超过3个月。依从性定义为处方后继续使用PAP的患者百分比,依从性定义为在70%的监测天数中平均每晚使用超过4小时。结果小儿患者中男性11例(64.7%),成人患者中男性141例(84.4%)。儿童患者平均年龄为8.0岁(6.50 ~ 12.50岁),成人患者平均年龄为50.0岁(41.00 ~ 58.00岁)。两组患者的平均呼吸暂停低通气指数(AHI) (37.0 vs 50.7)和最低氧饱和度(79.4% vs 75.5%)无统计学差异。最长的呼吸暂停有显著差异(25.9秒vs 50.8秒)(p=0.000)。使用PAP 18个月后,AHI从37.0降至5.1,而50.7降至2.6,依从性从94.1%降至41.2%,从90.4%降至38.9% (p=0.944),依从性从64.7%降至28.9%,从67.0%降至29.3% (p=0.268)。结论:与成人相比,儿童PAP的依从性和依从性无显著差异。

Abstract Introduction Good sleep quality is critical for good sleep health, but how sleep quality is defined remains uncertain; most defining it based solely on subjective or objective measures, and more recently, a combination of the two. PSG-derived sleep efficiency and WASO are linked to subjective sleep quality in healthy adults, but whether this is the same in adolescents (an age group notorious for not getting enough sleep), remains unknown. Aims To investigate which objective measures of sleep correlate with next-day ratings of sleep quality (primary outcome), sleep sufficiency, morning and daytime sleepiness, mood and concentration. Methods Seventy-one 16-17 y-olds (50% female) without anxiety/depression symptoms, completed a week of actigraphy and daily ratings of the subjective elements described above (469 days analysed). Statistical analyses used generalised estimating equation models. Results In unadjusted models, sleep quality showed significant within- and between-subject relationships with variables of sleep timing, amount, efficiency and variability. However after adjustment, total sleep time (TST) was the only metric that remained significant; for every 1 h less TST/night, teens were 1.56 (95%CI: 1.29, 1.88) times more likely to rate their sleep quality as poor rather than good. TST also correlated with daily mood ratings, and awakenings with morning sleepiness. No other significant relationships were found. Discussion The key sleep metric contributing to perceptions of sleep quality in adolescents was in fact one related to sleep quantity. Surprisingly, none of the sleep quality metrics used in sleep quality guidelines, linked to subjective ratings of sleep quality in this age group.
摘要:良好的睡眠质量对良好的睡眠健康至关重要,但如何定义睡眠质量仍然不确定;大多数人仅仅根据主观或客观的衡量标准来定义它,最近,两者结合在一起。在健康成年人中,psg衍生的睡眠效率和WASO与主观睡眠质量有关,但这是否适用于青少年(一个以睡眠不足而臭名昭著的年龄组),目前尚不清楚。目的探讨哪些客观的睡眠指标与第二天的睡眠质量评分(主要结果)、睡眠充足性、早晨和白天嗜睡、情绪和注意力相关。方法71名16-17岁无焦虑/抑郁症状的青少年(50%为女性)完成了为期一周的活动描记和上述主观因素的每日评分(分析469天)。统计分析采用广义估计方程模型。结果:在未调整的模型中,睡眠质量与睡眠时间、睡眠量、睡眠效率和可变性等变量在受试者内部和受试者之间表现出显著的关系。然而,调整后,总睡眠时间(TST)是唯一仍然显著的指标;每晚睡眠时间每减少1小时,青少年认为自己睡眠质量差的可能性要高出1.56倍(95%可信区间:1.29,1.88)。TST还与日常情绪评级、早晨睡意有关。没有发现其他重要的关系。影响青少年睡眠质量的关键睡眠指标实际上与睡眠量有关。令人惊讶的是,睡眠质量指南中使用的睡眠质量指标都与这个年龄段的睡眠质量主观评分无关。

Abstract Preliminary findings from this study were presented as a poster (P376) at Sleep Europe 2022 (https://doi.org/10.1111/jsr.13740). Introduction Sleep loss is presumed by academics and esport (organised competitive video-game play) athletes to be an in-game esport performance hindrance, primarily due to its well understood effects on multiple domains of cognitive performance. However, the effects of acute sleep loss specifically on esports performance have not been explored. We aimed to elucidate whether total sleep deprivation degrades in-game performance in the popular esport ‘Rocket League’. Methods Forty habitual Rocket League players were paired according to in-game ability level (twenty pairs), with one assigned to a control group (CON) and the other assigned to an intervention group (TSD). Two test sessions took place, in which paired players completed subjective and cognitive performance measures, and played seven Rocket League matches against one another. In one session, both players in a pair were well rested, while in the other, CON was rested while TSD was sleep deprived. Results Acute total sleep deprivation resulted in higher self-reported sleepiness, lower alertness and motivation, poorer performance on the Psychomotor Vigilance Task (PVT) and two-choice component of the Category Switch Task (CST). Despite this, overall in-game esport performance did not worsen due to sleep deprivation, although exploratory analysis suggests potential in-game strategy change. Discussion Our findings do not suggest that sleep loss is inconsequential for esport athletes, but rather suggest that acute bouts of sleep loss of similar/lesser severity may not be a primary concern for in-game esports performance.
该研究的初步结果在2022年欧洲睡眠大会(https://doi.org/10.1111/jsr.13740)上以海报(P376)的形式发表。学者和电子竞技(有组织的竞争性电子游戏)运动员认为睡眠不足是电子竞技中的表现障碍,主要是因为它对认知表现的多个领域产生了众所周知的影响。然而,急性睡眠不足对电子竞技表现的影响还没有被研究过。我们的目的是阐明完全睡眠剥夺是否会降低热门电子竞技“火箭联盟”的游戏表现。方法将40名《火箭联盟》习惯性玩家按游戏能力水平进行配对(20对),1人作为对照组(CON), 1人作为干预组(TSD)。他们进行了两次测试,让成对的玩家完成主观和认知表现测试,并相互进行了七场火箭联盟比赛。在一组中,两名玩家都得到了充分的休息,而在另一组中,CON得到了休息,而TSD则被剥夺了睡眠。结果急性完全睡眠剥夺导致自述嗜睡增加,警觉性和动机降低,在精神运动警戒任务(PVT)和类别转换任务(CST)的两项选择任务中的表现较差。尽管如此,游戏中的整体电子竞技表现并没有因为睡眠不足而恶化,尽管探索性分析表明游戏中的策略可能会发生变化。我们的研究结果并不表明睡眠不足对电子竞技运动员来说是无关紧要的,而是表明严重程度相似或较轻的急性睡眠不足可能不是游戏中电子竞技表现的主要问题。

Abstract Objective We investigated the relationships between subjective and objective sleep and lifestyle factors (i.e., nap duration, screentime, chronotype, use of tobacco, alcohol, caffeine, and medications) in young adults who sustained traumatic brain injury (TBI) in childhood. Methods We report cross-sectional data collected at 20 years post-childhood TBI, as part of a prospective study. Participants included 54 young adults with TBI (Mean age, 27.7years) who were assessed at 20 years postinjury (mild (n = 14), moderate (n = 27), and severe (n = 13) TBI) and 13 healthy controls (Mean age, 26.0 years). The Pittsburgh Sleep Quality Index and actigraphy were used to assess sleep outcomes, and lifestyle factors were assessed with study-designed measures. Results Results showed that poor subjective sleep quality was significantly associated with evening chronotype (p &lt; 0.001) and tobacco use (p &lt; 0.001), while being a parent (p = 0.038) and alcohol use (p = 0.035) were significantly associated with poorer objective sleep efficiency in the TBI group. Discussion These preliminary findings highlight interesting associations between poor sleep quality and lifestyle factors in young adults who sustained TBI in childhood, and indicate the need to further explore these relationships in this TBI population to inform on potential avenues for sleep interventions.
摘要目的探讨儿童期创伤性脑损伤(TBI)患者主客观睡眠与生活方式因素(即午睡时间、屏幕时间、睡眠类型、烟草、酒精、咖啡因和药物使用)之间的关系。方法:作为前瞻性研究的一部分,我们报告了20年后儿童TBI的横断面数据。参与者包括54名年轻成年TBI患者(平均年龄27.7岁),他们在损伤后20年(轻度(n = 14),中度(n = 27)和重度(n = 13) TBI)和13名健康对照者(平均年龄26.0岁)进行评估。匹兹堡睡眠质量指数和活动记录仪被用来评估睡眠结果,生活方式因素被用来评估研究设计的措施。结果结果表明,主观睡眠质量差与夜间睡眠类型显著相关(p <0.001)和烟草使用(p <0.001),而在TBI组中,为人父母(p = 0.038)和饮酒(p = 0.035)与较差的客观睡眠效率显著相关。这些初步研究结果突出了童年经历过脑外伤的年轻人睡眠质量差和生活方式因素之间的有趣关联,并表明需要进一步探索这些脑外伤人群的关系,以提供潜在的睡眠干预途径。

Abstract Introduction Upper airway reflex responses to negative pressure are important to prevent upper airway narrowing and closure. Recent evidence indicates ~30% of people with multiple sclerosis (MS) have an impaired upper airway dilator reflex response. Thus, the aims of this study were to compare genioglossus muscle reflex responses and upper airway collapsibility in non-obese people with MS, with and without OSA. Methods Non-obese adults with MS and OSA vs MS without OSA were instrumented with pressure sensors at the choanae and epiglottis. Bipolar fine wires were inserted into the genioglossus. A nasal mask and pneumotachograph were attached to a breathing circuit to deliver brief (~250ms) suction pressure (~-12cmH2O) during early inspiration every 2-10 breaths while awake. Genioglossus reflex onset latency, peak latency and peak amplitude were quantified. The upper airway collapsibility index was the percent difference between choanal and epiglottic airway pressures during negative pressure. Results 15 people with MS (6 males), aged 48±13years, BMI=25±3kg/m-2 and AHI=13±17events/h (mean±SD) were studied. 47% had OSA (AHI&gt;10events/h). Genioglossus reflex excitation onset latency (22±2 vs. 24±19ms), peak excitation latency (37±11 vs. 38±23ms) and peak amplitude (258±125 vs. 205±95%) were not different between OSA vs. non-OSA. The upper airway was more collapsible in people with OSA (49±32 vs. 17±16%, p=0.04). Conclusions There is a high prevalence of OSA among non-obese people with MS. There was no systematic difference in upper airway dilator muscle function. However, the upper airway is ~65% more collapsible in people with MS and OSA despite absence of obesity.
上呼吸道对负压的反射反应是防止上呼吸道狭窄和关闭的重要因素。最近的证据表明,约30%的多发性硬化症(MS)患者有上呼吸道扩张器反射反应受损。因此,本研究的目的是比较非肥胖多发性硬化症患者(伴和不伴OSA)的颏舌肌反射反应和上呼吸道塌陷性。方法对非肥胖成人多发性硬化症、阻塞性睡眠呼吸暂停与非阻塞性睡眠呼吸暂停的多发性硬化症患者在耳道和会厌处安装压力传感器。双极细导线插入颏舌肌。在清醒状态下,每2-10次呼吸,将鼻罩和气描仪连接到呼吸回路上,在早期吸气时提供短暂(~250ms)的吸入压力(~-12cmH2O)。对舌颏反射的起病潜伏期、峰潜伏期和峰幅进行量化。上呼吸道湿陷性指数为负压时后气道与会厌气道压力差的百分比。结果15例MS患者(男6例),年龄48±13岁,BMI=25±3kg/m-2, AHI=13±17events/h (mean±SD)。47%发生OSA (ahi10事件/小时)。舌颏反射兴奋发作潜伏期(22±2 vs. 24±19ms)、兴奋峰潜伏期(37±11 vs. 38±23ms)和峰幅(258±125 vs. 205±95%)在OSA与非OSA之间无显著差异。阻塞性睡眠呼吸暂停患者的上气道更易折叠(49±32比17±16%,p=0.04)。结论非肥胖多发性硬化症患者存在较高的阻塞性睡眠呼吸暂停患病率,两组患者上气道扩张肌功能无系统性差异。然而,尽管没有肥胖,MS和OSA患者的上呼吸道可折叠性要高出约65%。

Abstract Introduction Light plays an important role in the timing of children’s circadian system. Artificial manipulation of the timing, intensity, spectra, and duration of light exposure has increased, but with little consideration of the impact on children’s development, health, and wellbeing. Children are exposed to brighter nights, darker days, and less natural light environments than prior generations. Exploring the 24-hour light environment is a critical first step in understanding how light affects children. Methods We conducted a pilot feasibility and acceptability study. The study is of children aged 5 – 8 years. Children wore a miniature spectrometer and an actigraph for 48-hours. During this period, their parents completed a survey and daily time-use diary. At the end of the study, children undergo a short evaluation interview, as this is a new form of wearable not previously used with children. This study examines the feasibility and potential utility of this form of measurement. Results 5 children have been recruited into the study (3 boys, 2 girls). Initial feasibility testing with children supports high acceptability and adherence to the study protocol. This presentation will focus on both the technology development aspects, useability and feasibility in children, and preliminary results. Discussion This study presents preliminary data that supports the feasibility of novel light exposure metrics. Understanding the impact of increased use of digital devices by children, and increased control and manipulation of their light environments, requires new measures and protocols. These tools will help improve understanding of the effects of light on children’s sleep.
光在儿童昼夜节律系统的定时中起着重要的作用。对光照时间、强度、光谱和持续时间的人为操纵有所增加,但很少考虑对儿童发育、健康和福祉的影响。与前几代人相比,孩子们暴露在更亮的夜晚,更暗的白天和更少的自然光环境中。探索24小时的光环境是了解光线如何影响儿童的关键的第一步。方法进行初步的可行性和可接受性研究。这项研究的对象是5 - 8岁的儿童。孩子们佩戴微型光谱仪和活动记录仪48小时。在此期间,他们的父母完成了一项调查和每日时间使用日记。在研究结束时,孩子们接受了一个简短的评估访谈,因为这是一种新的可穿戴设备,以前没有在儿童身上使用过。本研究考察了这种测量形式的可行性和潜在效用。结果共纳入5例儿童(男3例,女2例)。对儿童进行的初步可行性测试支持研究方案的高可接受性和依从性。本报告将着重于技术发展方面,儿童的可用性和可行性,以及初步结果。本研究提供的初步数据支持了新型光暴露度量的可行性。了解儿童越来越多地使用数字设备以及越来越多地控制和操纵他们的光环境的影响,需要新的措施和协议。这些工具将有助于提高对光线对儿童睡眠影响的理解。
