Objective

To examine the association between changes in self-reported neighborhood stressors and sleep quality and determine whether this varied by sociocultural context among Puerto Rican young adults.

Methods

Data come from the Boricua Youth Study Health Assessment, a sample of Puerto Rican young adults from San Juan, Puerto Rico, and South Bronx, New York (n = 818; mean age = 22.9 years). Sleep quality was assessed using the Pittsburgh Sleep Quality Index (PSQI). Neighborhood social stressors (disorder, social cohesion, and safety) were parent-reported in childhood and self-reported in young adulthood and categorized into: low in childhood/young adulthood (reference group), high in childhood/low in young adulthood, low in childhood/high in young adulthood, and high in childhood/young adulthood. Sociocultural context was based on participant residence during childhood (San Juan vs. South Bronx).

Results

Adjusting for sociodemographic factors, living with high neighborhood stressors in both childhood and young adulthood (prevalence ratios = 1.30, 95% CI: 1.01, 1.66) was associated with overall poor sleep (PSQI score >5). Among PSQI components, living with high neighborhood stressors in young adulthood only or in both time periods was associated with worse subjective sleep quality and daytime dysfunction. Additionally, there were various associations between the neighborhood stressor measures and PSQI components. Results did not differ by sociocultural context.

Conclusion

Findings suggest that living with high levels of neighborhood stressors during childhood and young adulthood may have a cumulative adverse impact on sleep quality in young adulthood.

方法数据来自波多黎各圣胡安和纽约南布朗克斯的波多黎各青壮年样本--波多黎各青年研究健康评估（Boricua Youth Study Health Assessment）（n = 818；平均年龄 = 22.9 岁）。睡眠质量采用匹兹堡睡眠质量指数（PSQI）进行评估。邻里社会压力因素（混乱、社会凝聚力和安全）由儿童时期的家长报告和青年时期的自我报告组成，并分为：儿童时期/青年时期低（参照组）、儿童时期高/青年时期低、儿童时期低/青年时期高以及儿童时期/青年时期高。社会文化背景基于受试者童年时期的居住地（圣胡安区与南布朗克斯区）。结果经社会人口学因素调整后发现，童年时期和青年时期生活在高邻里压力下（患病率比=1.30，95% CI：1.01，1.66）与总体睡眠质量差（PSQI 得分>5）有关。在 PSQI 的各组成部分中，仅在青年时期或在两个时期生活在高邻里压力下与主观睡眠质量和日间功能障碍较差有关。此外，邻里压力测量与 PSQI 各组成部分之间也存在各种关联。结论研究结果表明，童年和青年时期生活在高水平邻里压力下可能会对青年时期的睡眠质量产生累积性不利影响。

Objective

The purpose of this study was to evaluate the psychometric properties of the Couples' Sleep Conflict Scale, a new measure designed to identify the extent of conflict around sleep in romantic relationships.

Methods

Data from an individual sample (N = 158) and dyadic sample (N = 143 mixed-gender couples) in romantic relationships were used to examine the psychometric properties of the Couples' Sleep Conflict Scale, including internal consistency, convergent and divergent validity, and whether the factor structure differed between couples with concordant and discordant chronotypes.

Results

Results revealed that the Couples' Sleep Conflict Scale fit a 1-factor solution of 5 items, a summed or mean score can be used, and that it is reliable for both men and women. In addition, more relational sleep conflict was associated with both their own and their partners’ poorer sleep hygiene, worse sleep quality, and more daytime sleepiness as well as more general relationship conflict, lower relationship satisfaction, and higher anxious and avoidant attachment. Finally, we found partial measurement invariance for factor loadings, intercepts, and latent variable variances between couples with concordant vs. discordant chronotypes.

Conclusion

The Couples' Sleep Conflict Scale is a brief measure that can be used in both research and in health care settings to examine how sleep-related conflict can affect both sleep and relationship quality among couples.

目的本研究旨在评估情侣睡眠冲突量表的心理测量特性，这是一种新的测量方法，旨在确定恋爱关系中围绕睡眠的冲突程度。方法使用恋爱关系中个人样本（N = 158）和双人样本（N = 143 对混合性别情侣）的数据来检验情侣睡眠冲突量表的心理测量特性，包括内部一致性、收敛效度和发散效度，以及具有一致和不一致时型的情侣之间的因子结构是否存在差异。结果结果显示，夫妻睡眠冲突量表符合由 5 个项目组成的单因素解，可以使用总分或平均分，而且对男性和女性都是可靠的。此外，夫妻睡眠冲突越多，其自身和伴侣的睡眠卫生状况越差、睡眠质量越差、白天嗜睡越多，夫妻关系冲突越多、夫妻关系满意度越低、焦虑和回避型依恋程度越高。最后，我们发现，在时间型一致与时间型不一致的夫妻之间，因子载荷、截距和潜变量方差都存在部分测量不变量。

Objective

Sleep undergoes major changes during the first year of life, but the characteristics of sleep among infants in low and middle-income countries are not well documented. This study describes sleep characteristics and changes in sleep patterns in infants at 6 and 12 months of age from Bhaktapur, Nepal.

Methods

This was a community-based longitudinal study comprising 735 infants. Sleep characteristics were obtained by interview with the mother using the Brief Infant Sleep Questionnaires. The stability of sleep duration and night awakenings were estimated by logistic regression analysis.

Results

Cosleeping in the parent’s bed at 6 and 12 months of age was almost universal (>97%). At 6 months of age, 254 (35%) and at 12 months of age, 341 (46%) infants had a total 24-hour sleep duration <12 hours. Night awakenings >3 times per night were common (65%) both at 6 and 12 months of age. Infants with frequent nightly awakenings at 6 months had increased odds of frequent nightly awakenings at 12 months (OR = 2.2; 95% CI: 1.6, 2.9). Very few (<3%) mothers reported sleep problems in their infants at 6 and 12 months of age.

Conclusions

Cosleeping was almost universal among Nepalese infants, and very few of the mothers reported sleep problems in their infants. Infants at 6 and 12 months had similar patterns for both sleep duration and nocturnal awakenings. For infants, there were increased odds of having similar sleep duration and nocturnal awakening at 6 and 12 months.

目的：睡眠在婴儿出生后的第一年会发生重大变化，但中低收入国家婴儿的睡眠特征却没有得到很好的记录。本研究描述了尼泊尔巴克塔普尔 6 个月和 12 个月婴儿的睡眠特征和睡眠模式的变化：这是一项以社区为基础的纵向研究，共有 735 名婴儿参加。通过使用婴儿睡眠简明问卷对母亲进行访谈，了解婴儿的睡眠特征。通过逻辑回归分析估计了睡眠时间和夜间觉醒的稳定性：6个月和12个月大的婴儿几乎都在父母床上同睡（>97%）。在 6 个月大和 12 个月大的婴儿中，分别有 254 名（35%）和 341 名（46%）婴儿的 24 小时总睡眠时间为每晚 3 次（65%）。6 个月时频繁夜醒的婴儿在 12 个月时频繁夜醒的几率增加（OR=2.2；95% CI：1.6，2.9）。极少数（结论：尼泊尔婴儿几乎都有同睡的习惯，很少有母亲报告婴儿有睡眠问题。6 个月和 12 个月的婴儿在睡眠时间和夜间觉醒方面的模式相似。对于婴儿来说，6 个月和 12 个月时睡眠时间和夜间觉醒次数相似的几率增加。

Objectives

Attrition and nonadherence are common concerns that can distort findings in clinical trials. This study examines the potential for systematic attrition in the largest sample to date of adolescents undergoing sleep manipulation.

Methods

Using pooled data across two trials involving 242 adolescents, a cumulative logistic regression tested whether demographics and baseline sleep predicted study completion/adherence.

Results

Race, a composite measure of socioeconomic status, and its elements (e.g., income, education) individually predicted completion/adherence. When entered concurrently into a multivariate predictive model, only socioeconomic status and study (trial A vs. B) were significant. Adolescents from households with higher socioeconomic status were more likely to complete or adhere to the protocol than those from households with lower socioeconomic status, p < .001.

Conclusions

Systematic attrition in sleep manipulation research could distort conclusions about under-resourced groups. Future sleep trials should intentionally measure systemic/structural factors and adopt strategies to recruit and retain participants from various backgrounds.

Objectives

Poor quality sleep can impact emotions and emotion regulation, resulting in a “sleep-mood” cycle where poor sleep affects mood and vice-versa. This relationship is poorly understood during early childhood, when sleep patterns and emotion displays are rapidly changing. This study aimed to understand the day-to-day effects of poor sleep on emotions in preschoolers by using objective (actigraphy) and subjective (ecological momentary assessment) measures to assess both between- and within-child effects. We hypothesized that disrupted sleep would lead to affect disruptions and vice versa.

Methods

This study included 133 preschoolers and their caregivers recruited from the community. Children’s sleep was measured via actigraphy (ActiGraph GT3X+) across 1 week. Affect was collected concurrently via caregiver report during an ecological momentary assessment protocol. Caregivers reported on their child’s affect four times per day: morning, afternoon, early evening, and before bed.

Results

Multilevel modeling analyses revealed that children with sleep disturbances displayed less positive affect overall, more negative affect in the evenings, and alterations in positive affect lability, and that daytime affect was associated with subsequent nighttime sleep. Within-child associations also showed fluctuations in positive affect correlated with shorter sleep durations and later bedtimes.

Conclusions

This study identified both between- and within-child associations between sleep and affect in early childhood, revealing a dynamic and reciprocal relationship between the two. These findings highlight the importance of considering both sleep and affect in early childhood interventions, as promoting positive affect may enhance sleep quality and vice versa.

目标睡眠质量差会影响情绪和情绪调节，从而形成 "睡眠-情绪 "循环，即睡眠质量差影响情绪，反之亦然。在睡眠模式和情绪表现迅速变化的幼儿期，人们对这一关系的了解甚少。本研究旨在通过使用客观（行为记录仪）和主观（生态瞬间评估）测量方法来评估儿童之间和儿童内部的影响，从而了解睡眠不足对学龄前儿童情绪的日常影响。我们假设睡眠中断会导致情绪紊乱，反之亦然：本研究包括从社区招募的 133 名学龄前儿童及其照顾者。儿童的睡眠情况通过行动记录仪（ActiGraph GT3X+）进行了为期一周的测量。在生态学瞬间评估方案中，通过看护者的报告同时收集情绪。照顾者每天报告四次孩子的情绪：上午、下午、傍晚和睡前：多层次建模分析表明，睡眠障碍儿童总体上表现出较少的积极情绪，晚上表现出较多的消极情绪，积极情绪的易变性有所改变，而且白天的情绪与随后的夜间睡眠有关。儿童内部的关联也表明，积极情绪的波动与睡眠时间缩短和就寝时间推迟有关：本研究发现了幼儿期睡眠与情绪之间的儿童间和儿童内关联，揭示了两者之间的动态互惠关系。这些发现强调了在儿童早期干预中同时考虑睡眠和情绪的重要性，因为促进积极情绪可能会提高睡眠质量，反之亦然。

Introduction

Insomnia symptoms are associated with poor physical and mental health. Exercise is associated with good sleep while sedentary behavior is associated with poor sleep. This study investigated the longitudinal, dynamic associations among exercise, sedentary behavior, and insomnia symptoms.

Methods

Seven hundred and fifty-six adults (M_age = 47.2 years, 54.9% female) took part in an online longitudinal study investigating sleep and health across the lifespan. Participants reported duration of moderate-to-strenuous exercise, percentage of day spent sitting, and insomnia symptoms (Insomnia Severity Index [ISI]). The ISI was scored as a total score and two-factor scores: (1) Sleep Disturbance (items 1, 2, 3) and (2) Daytime Dysfunction (items 4, 5, 6, 7). Multilevel modeling was used to examine the typical (i.e., between-persons) and individual (i.e., within-persons) associations among sedentary behavior, exercise, and insomnia symptoms.

Results

Sedentary behavior was significantly associated with total ISI scores at both the between-person and within-person levels (β = 0.036, t = 3.23, p = .001; β = 0.014, t = 1.99, p = .048). Both between-persons and within-person levels of sedentary behavior were associated with Daytime Dysfunction (β = 0.028, t = 3.79, p < .001; β = 0.009, t = 2.08, p = .039). Exercise was associated with total ISI and Daytime Dysfunction scores at the between-persons level but not at the within-persons level (β = 0.028, t = 2.57, p = .01; β = − 0.002, t = − 3.02, p = .003).

Conclusions

Sedentary behavior was a more consistent and robust predictor of insomnia symptoms than exercise. The association between sedentary behavior and insomnia symptoms was dynamic in that when an individual reported being more sedentary than their norm, they also reported more insomnia symptoms. Future analyses should examine potential moderator variables and comorbid conditions.

简介失眠症状与身心健康状况不佳有关。运动与良好睡眠有关，而久坐不动与睡眠不佳有关。本研究调查了运动、久坐行为和失眠症状之间的纵向动态关联：756 名成年人（年龄 47.2 岁，54.9% 为女性）参加了一项在线纵向研究，调查整个生命周期的睡眠和健康状况。参与者报告了中度到剧烈运动的持续时间、一天中坐着的时间比例以及失眠症状（失眠严重程度指数 [ISI]）。失眠严重程度指数分为总分和两个因子分：(1) 睡眠紊乱（项目 1、2、3）和 (2) 白天功能障碍（项目 4、5、6、7）。采用多层次模型研究了久坐行为、运动和失眠症状之间的典型（即人与人之间）和个体（即人与人之间）关联：在人与人之间和人与人之间的水平上，久坐行为与 ISI 总分都有明显关联（β = 0.036，t = 3.23，p = .001；β = 0.014，t = 1.99，p = .048）。人与人之间和人与人之间的久坐行为水平都与日间功能障碍有关（β = 0.028，t = 3.79，p 结论）：与运动相比，久坐行为对失眠症状的预测更稳定、更可靠。久坐行为与失眠症状之间的关系是动态的，当一个人报告的久坐程度高于常人时，他也会报告更多的失眠症状。未来的分析应研究潜在的调节变量和合并症。

Background

Sleep is increasingly recognized as a multidimensional construct that occurs within the 24-hour day. Despite advances in our understanding, studies continue to consider the relationship between sleep, sedentary time and physical activity separately, and not as part of the 24-hour day.

Aims

To determine the association between the 24-hour activity composition and dimensions of healthy sleep.

Methods

This study examined data on 1168 children (mean age 12 years; 49% female) and 1360 adults (mean age 44 years; 87% female) collected as part of the Child Health CheckPoint study. Participants were asked to wear a GENEActiv monitor (Activinsights, Cambs, UK) on their nondominant wrist for eight consecutive days to measure 24-hour time-use. Compositional data analysis was used to examine the association between time use (actigraphy-derived sleep duration, sedentary time, light physical activity and moderate-vigorous physical activity) and dimensions of healthy sleep. Healthy sleep was conceptualized in terms of continuity/efficiency, timing, alertness/sleepiness, satisfaction/quality, and regularity. Time allocations were also examined.

Results

The 24-hour activity composition was significantly associated with all objectively measured and self-report dimensions of healthy sleep in both children and adults. Allocating more time to sleep was associated with earlier sleep onsets, later sleep offsets, less efficient and more consistent sleep patterns for both children and adults.

Conclusion

This study highlights the integral relationship between daily activities and dimensions of sleep. Considering sleep within the 24-hour day activity composition framework may help inform lifestyle decisions to improve sleep health.

背景：人们越来越认识到睡眠是一天 24 小时中的一个多维结构。目的：确定 24 小时活动构成与健康睡眠各维度之间的关联：本研究调查了儿童健康检查点研究中收集的 1168 名儿童（平均年龄 12 岁；49% 为女性）和 1360 名成人（平均年龄 44 岁；87% 为女性）的数据。参与者被要求连续八天在非支配腕上佩戴 GENEActiv 监测器（Activinsights，英国卡姆布斯），以测量 24 小时的时间使用情况。我们采用了合成数据分析来研究时间使用（通过行动计法得出的睡眠时间、久坐时间、轻体力活动和中等强度体力活动）与健康睡眠各维度之间的关联。健康睡眠的概念包括连续性/效率、时间、警觉性/睡意、满意度/质量和规律性。此外，还对时间分配进行了研究：结果：在儿童和成人中，24 小时活动构成与健康睡眠的所有客观测量和自我报告维度都有明显关联。为睡眠分配更多时间与儿童和成人的睡眠开始时间提前、睡眠结束时间推迟、睡眠效率降低和睡眠模式更稳定有关：这项研究强调了日常活动与睡眠之间不可分割的关系。在一天 24 小时的活动构成框架内考虑睡眠问题，有助于为改善睡眠健康的生活方式决策提供依据。

Goal and aims

To test sleep/wake transition detection of consumer sleep trackers and research-grade actigraphy during nocturnal sleep and simulated peri-sleep behavior involving minimal movement.

Focus technology

Oura Ring Gen 3, Fitbit Sense, AXTRO Fit 3, Xiaomi Mi Band 7, and ActiGraph GT9X.

Reference technology

Polysomnography.

Sample

Sixty-three participants (36 female) aged 20-68.

Design

Participants engaged in common peri-sleep behavior (reading news articles, watching videos, and exchanging texts) on a smartphone before and after the sleep period. They were woken up during the night to complete a short questionnaire to simulate responding to an incoming message.

Core analytics

Detection and timing accuracy for the sleep onset times and wake times.

Additional analytics and exploratory analyses

Discrepancy analysis both including and excluding the peri-sleep activity periods. Epoch-by-epoch analysis of rate and extent of wake misclassification during peri-sleep activity periods.

Core outcomes

Oura and Fitbit were more accurate at detecting sleep/wake transitions than the actigraph and the lower-priced consumer sleep tracker devices. Detection accuracy was less reliable in participants with lower sleep efficiency.

Important additional outcomes

With inclusion of peri-sleep periods, specificity and Kappa improved significantly for Oura and Fitbit, but not ActiGraph. All devices misclassified motionless wake as sleep to some extent, but this was less prevalent for Oura and Fitbit.

Core conclusions

Performance of Oura and Fitbit is robust on nights with suboptimal bedtime routines or minor sleep disturbances. Reduced performance on nights with low sleep efficiency bolsters concerns that these devices are less accurate for fragmented or disturbed sleep.

目标和目的测试消费类睡眠追踪器和研究级动电仪在夜间睡眠和涉及最小运动的模拟围睡眠行为中的睡眠/觉醒转换检测。样本63名参与者（36名女性），年龄在20-68岁之间。设计参与者在睡眠前后使用智能手机进行常见的围睡眠行为（阅读新闻文章、观看视频和交换短信）。核心分析睡眠开始时间和唤醒时间的检测和计时准确性。其他分析和探索性分析包括和不包括围睡眠活动期的差异分析。核心结果Oura和Fitbit在检测睡眠/觉醒转换方面的准确性高于actigraph和价格较低的消费者睡眠追踪设备。重要附加结果纳入围睡眠期后，Oura 和 Fitbit 的特异性和 Kappa 显著提高，但 ActiGraph 的特异性和 Kappa 没有提高。所有设备都在一定程度上将无动于衷的唤醒错误归类为睡眠，但这种情况在 Oura 和 Fitbit 上较少发生。核心结论Oura 和 Fitbit 在睡前常规不理想或有轻微睡眠障碍的夜晚表现良好。在睡眠效率较低的夜晚，Oura 和 Fitbit 的性能有所下降，这让人们更加担心这些设备对零碎或紊乱睡眠的准确性较低。
