Pediatric sleep health: It matters, and so does how we define it

Bedtime Regularity and Sleep Sufficiency in Children With Tourette Syndrome

BACKGROUND

Despite research demonstrating sleep disturbance in children with Tourette syndrome (TS), few studies have examined bedtime regularity and sleep sufficiency, two important sleep health dimensions. Therefore, this study examined bedtime regularity and sleep sufficiency in children with TS relative to matched healthy control subjects, and its associated demographic, clinical, and behavioral factors.

METHODS

Participants were 384 parents or caregivers of children aged three to 17 years, including 192 with current TS and 192 matched healthy control subjects drawn from the 2020-2021 cycle of the National Survey of Children's Health. Parents completed questions assessing demographic (i.e., age, race, sex), clinical (i.e., attention-deficit/hyperactivity disorder [ADHD], autism spectrum disorder, anxiety, depression, tic severity, behavioral or conduct problems, ADHD medication, health condition-related impairment), and behavioral (i.e., screen time) characteristics. Mann-Whitney U test and chi-square test of independence were performed to compare groups on bedtime regularity and sleep sufficiency, respectively. Ordinal regression and binary logistic regression without and with backward elimination were performed to evaluate indicators of bedtime regularity and sleep sufficiency, respectively, in children with TS.

RESULTS

Children with current TS had significantly poorer bedtime regularity, but not sleep sufficiency, relative to matched healthy control subjects. In children with TS, anxiety and two or more hours of daily screen time were associated with higher likelihood of poor bedtime regularity. Autism was associated with lower likelihood of insufficient sleep, and depression was associated with increased likelihood of insufficient sleep.

CONCLUSIONS

Findings put forth screen time, anxiety, and depression as intervention targets to optimize sleep health in children with TS.

Sleep insufficiency and bedtime irregularity in children with ADHD: A population-based analysis

BACKGROUND

Sleep is impaired in children with attention-deficit/hyperactivity disorder (ADHD). However, population-based examination of indicators of sleep insufficiency and bedtime irregularity is limited. This investigation examined associations between ADHD, weeknight sleep insufficiency, and bedtime irregularity in a nationally-representative child sample, and indicators of these sleep outcomes in ADHD.

METHODS

Parents of children aged 3-17 years with ADHD (n = 7671) were surveyed through the 2020-2021 National Survey of Children's Health. Inverse probability of treatment weighting generated a weighted matched control sample (n = 51,572). Weighted generalized linear models were performed without and with age-stratification to examine associations between ADHD and sleep, adjusting for sociodemographics in the full sample, and between nineteen sociodemographic and clinical variables and sleep in ADHD.

RESULTS

Having ADHD was associated with increased odds of sleep insufficiency and bedtime irregularity relative to controls, even after adjusting for sociodemographic variables. In ADHD, older age was associated with lower sleep insufficiency and greater bedtime irregularity. Black race, increased poverty, higher ADHD severity, depression, and increased screen time were associated with greater sleep insufficiency and bedtime irregularity. Adverse childhood experiences (ACEs) were associated with greater sleep insufficiency. Behavioral/conduct problems, female sex, and absence of both ADHD medication use and ASD diagnosis were associated with poorer bedtime irregularity. Age-stratified results are reported in text.

CONCLUSIONS

Children with ADHD face heightened risk for insufficient sleep and irregular bedtimes. Findings suggest intervention targets (e.g., Black race, poverty, depression, screen time) to improve both sleep insufficiency and bedtime irregularity. Results highlight ACEs and behavioral/conduct problems as targets to improve sleep insufficiency and bedtime regularity, respectively. Age-stratified findings are discussed.

The measurement of young children's nocturnal sleep health and the development of the Perception of Infant and Toddler Sleep Scale (PoITSS) in Aotearoa New Zealand whānau (families)

OBJECTIVES

To modify an existing questionnaire Brief Infant Sleep Questionnaire - Revised (BISQ-R) to ensure that it is suitable to measure nocturnal sleep health in a diverse sample of young children from Aotearoa New Zealand whānau (families), and to develop a "Perception of Infant and Toddler Sleep Scale" (PoITSS) to use as a primary outcome measurement in an upcoming trial.

METHODS

Items from the BISQ-R were adapted for use among ethnically diverse whānau, and tested online with caregivers of 0-2 year old children. A PoITSS score was generated by scaling the responses from three of the questionnaire items to create a value between 0 (very poor) and 10 (very good). Caregivers provided qualitative feedback about the ease of interpreting and answering questionnaire items.

RESULTS

Caregivers of 957 children (35% Māori, 12% Pacific) completed the questionnaire. Few differences in children's nocturnal sleep were observed by demographic characteristics. The mean PoITSS score was 6.9 (SD 2.3) and was slightly higher among Māori children (mean difference 0.4, 95% CI 0.1, 0.7). Test-retest indicated good reliability (ICC=0.81). While the majority (86%) of caregivers did not find it difficult to answer any of the items which formed the PoITSS, qualitative feedback indicated that simple modifications to some items would help ensure that they would be well understood by most caregivers.

CONCLUSIONS

Items from the BISQ-R were successfully adapted, and the PoITSS scale was shown to be appropriate, for use in ethnically diverse Aotearoa New Zealand whānau with young children.

The time sensitive and dose-responsive association between parental corporal punishment and sleep disturbances in preschoolers: A prospective cohort study

BACKGROUND

To examine whether parental corporal punishment is associated with increased risk of concurrent and later sleep disturbances among preschoolers, and whether the association is time-sensitive or dose-responsive.

METHODS

This 3-year prospective cohort study used data from the Shanghai Children's Health, Education and Lifestyle Evaluation, Preschool(SCHEDULE-P). Participants were newly enrolled preschoolers in November 2016(wave 1) and followed up in April 2018(wave 2) and April 2019(wave 3). Parents reported the children's corporal punishment experiences and sleep disturbances at each wave survey. Children's risk of sleep disturbances in relation to corporal punishment was examined using logistic regression, adjusting for children's age, gender, emotional/behavioral problems, family annual income, and maternal educational level.

RESULTS

The participants of 19,668 children included 9436(47.98 %) females, with a mean age of 3.73(SD = 0.29) years at wave 1. Exposure to corporal punishment was associated with increased odds of concurrent sleep disturbances at wave 1, 2, and 3 (aOR,1.57; 95 % CI, 1.40-1.75; P < .001; aOR,1.60; 95 % CI, 1.43-1.80; P < .001; aOR,1.74; 95 % CI, 1.54-1.95; P < .001), respectively. Exposure to corporal punishment at any wave of preschool was associated with increased odds of sleep disturbances at wave 3, and the risks were greater for proximal and accumulative corporal punishment exposure.

CONCLUSION

There is a time-sensitive and dose-responsive association between corporal punishment and sleep disturbance among preschoolers, with greater risk of sleep disturbances for proximal and accumulative exposure of corporal punishment. Promoting positive parenting strategies and avoiding corporal punishment can be a promising strategy to prevent and intervene sleep disturbances in preschoolers.

The enigma of sleep: Implications of sleep neuroscience for the dental clinician and patient

BACKGROUND

Sleep disturbances have been shown to result in considerable morbidity and mortality. It is important for dental clinicians to understand the neuroscience behind sleep disorders.

TYPES OF STUDIES REVIEWED

The authors conducted a search of the literature published from January 1990 through March 2024 of sleep medicine-related articles, with a focus on neuroscience. The authors prioritized articles about the science of sleep as related to dental medicine.

RESULTS

The authors found a proliferation of articles related to sleep neuroscience along with its implications in dental medicine. The authors also found that the intricate neuroscientific principles of sleep medicine are being investigated robustly. The salient features of, and the differences between, central and obstructive sleep apneas have been elucidated. Sleep genes, such as CRY, PER1, PER2, and CLOCK, and their relationship to cancer and neurodegeneration are also additions to this rapidly developing science.

CONCLUSIONS AND PRACTICAL IMPLICATIONS

The dental clinician has the potential to be the first to screen patients for possible sleep disorders and make prompt referrals to the appropriate medical professionals. This can be lifesaving as well as minimize potential future morbidity for the patient.

To sleep or to breastfeed: Associations between feeding method and sleep in infants and children

AIM

This study aimed to understand the association between feeding method, specifically breastfeeding versus non-breastfeeding, at 6 and 12 months and infant sleep over the first 3 years of life.

METHODS

A sample of 444 mother-infant dyads from the Maternal Adversity, Vulnerability and Neurodevelopment cohort were analysed. Based on retrospective maternal reports between 3-24 months, infants' breastfeeding status was determined at 6 and 12 months. Nocturnal sleep duration, longest period of consecutive sleep, and total sleep over 24 h were measured by maternal reports at 6, 12, 24 and 36 months.

RESULTS

Generalized Estimating Equations revealed no significant association between feeding status, both at 6 and 12 months, and nocturnal sleep duration or total sleep over 24 h between 6-36 months (p > 0.05). However, breastfeeding at both 6 and 12 months was associated with shorter periods of consecutive sleep, at 6 and 12 months (p < 0.05) but not at 24 and 36 months (p > 0.05).

CONCLUSION

Our findings suggest that breastfeeding seems to be associated with more infant sleep fragmentation but not with total sleep duration in early infancy. However, this sleep fragmentation does not persist into later infancy and early toddlerhood.

Perceptions of sleep health among African American mothers regarding their preschool-aged children: A qualitative study to decrease sleep health disparities

OBJECTIVES

African American children are documented as having poor sleep health due to shorter sleep duration, sleep timing, and sleep behaviors compared to White peers, contributing to child health disparities. Identifying cultural-environmental, and societal factors impacting a child's sleep among African American families is essential for developing interventions for this population. This study evaluated holistically why African American children may have poorer sleep health by examining sleep duration, timing, and behaviors. This was assessed by examining sleep-related beliefs, barriers, and facilitators to sleep schedules and routines. We also explored parental ideas for a sleep intervention.

METHODS

African American mothers of preschool-aged children (2-5years) were recruited using local partnerships and social media. Individual semistructured interviews were conducted by phone. Interviews were transcribed, coded, and analyzed thematically using grounded-theory.

RESULTS

Eighteen African American mothers completed the study. Five themes related to sleep emerged: The importance of adequate nighttime sleep, the influence of family and friends on parental sleep practices, the relationship between environmental and home dynamics on child sleep duration, the impact of acute and chronic societal-level stressors on family sleep health, and considerations for culturally tailored interventions to improve child sleep health.

CONCLUSIONS

Good sleep health was important among African American mothers. Cultural-environmental and societal factors significantly impact children's sleep health. Clinicians and researchers should be aware of financial resources and home dynamics leading to challenges with adequate sleep health when developing or adapting sleep interventions. Identifying cultural-environmental, and societal factors must be considered for targeted efforts to improve sleep health in African American children.

Sleep and fundamental movement skills in primary schoolchildren: The REACT project

OBJECTIVE

Whether sleep is related to fundamental movement skills (FMS) in the pediatric population is largely unknown. The objective of this study was to examine the association between sleep characteristics (duration, efficiency, regularity) and FMS proficiency levels in school-aged children.

METHODS

This cross-sectional study included 996 children (mean age: 8.3 ± 1.2 years) from 25 of the 32 primary schools in Matosinhos, northern Portugal. Data collection occurred between January and June 2022. Sleep was assessed using an ActiGraph wGT3X-BT accelerometer worn on the wrist for 7 consecutive days. FMS proficiency levels were assessed in the schools with a new digital platform (Meu Educativo®) that evaluated five object control skills (dribble, kick, catch, throw, and underhand roll), with a total score ranging between 5 and 15. Multilevel ordinal logistic regression was used to test the associations between sleep characteristics and FMS proficiency levels. Covariates included age, sex, body mass index z-score, socioeconomic status, and moderate-to-vigorous physical activity.

RESULTS

The results showed that sleep characteristics (duration, efficiency, and regularity) were not related to FMS proficiency. Being a boy, older age, and higher moderate-to-vigorous physical activity levels were all significantly associated with better FMS proficiency levels. There were no significant sex-by-age interactions.

CONCLUSION

Sleep was not found to be related to FMS performance in children. This finding suggests that sleep is not a good correlate of FMS proficiency levels in school-aged children, and attention should be dedicated to other more important factors such as skill-learning-specific physical activity.

The Complex Relationship between Sleep and Cognitive Reserve: A Narrative Review Based on Human Studies

Sleep and brain/cognitive/neural reserve significantly impact well-being and cognition throughout life. This review aims to explore the intricate relationship between such factors, with reference to their effects on human cognitive functions. The specific goal is to understand the bidirectional influence that sleep and reserve exert on each other. Up to 6 February 2024, a methodical search of the literature was conducted using the PubMed database with terms related to brain, cognitive or neural reserve, and healthy or disturbed sleep. Based on the inclusion criteria, 11 articles were selected and analyzed for this review. The articles focus almost exclusively on cognitive reserve, with no explicit connection between sleep and brain or neural reserve. The results evidence sleep's role as a builder of cognitive reserve and cognitive reserve's role as a moderator in the effects of physiological and pathological sleep on cognitive functions. In conclusion, the findings of the present review support the notion that both sleep and cognitive reserve are critical factors in cognitive functioning. Deepening comprehension of the interactions between them is essential for devising strategies to enhance brain health and resilience against age- and pathology-related conditions.

Investigation of the Association between Sleep Disorders with Subsequent Depression in Children and Adolescents-A Retrospective Cohort Study with 62,796 Patients

BACKGROUND

Poor quality of sleep is a widespread issue in modern society, and even children are being diagnosed with sleep disorders nowadays. Sleep disruption in children can lead to poor mental health in the long term. The present study aimed to evaluate the association between sleep disorders and subsequent depression in children and adolescents.

METHODS

This retrospective cohort study used electronic medical records from the IQVIATM Disease Analyzer database. It included children and adolescents aged 6-16 with an initial diagnosis of a sleep disorder and age- and gender-matched patients without sleep disorders treated by one of 274 office-based pediatricians in Germany between January 2010 and December 2022. The five-year cumulative incidence of depression in the cohorts with and without sleep disorders was studied with Kaplan-Meier curves using the log-rank test. Multivariable Cox regression analyses were used to assess the association between sleep disorders and depression.

RESULTS

The present study included 10,466 children and adolescents with and 52,330 without sleep disorder diagnosis (mean age 10 ± 3 years, 48% female). Within five years after the index date, 5% of sleep disorder patients and 2% of the matched non-sleep disorder cohort had been diagnosed with depression. A strong and significant association was observed between sleep disorders and subsequent depression (HR: 2.34; 95% CI: 2.09-2.63). This association was stronger in adolescents (HR: 3.78; 95% CI: 3.13-4.56) than in children. Upon the exclusion of depression diagnoses in the first year after the index date, the association between sleep disorders and depression remained strong and significant (HR: 1.92; 95% CI: 1.68-2.19).

CONCLUSIONS

This study indicates a strong and significant association between sleep disorders and depression.

Data-driven, generalizable prediction of adolescent sleep disturbances in the multisite Adolescent Brain Cognitive Development Study

STUDY OBJECTIVES

Sleep disturbances are common in adolescence and associated with a host of negative outcomes. Here, we assess associations between multifaceted sleep disturbances and a broad set of psychological, cognitive, and demographic variables using a data-driven approach, canonical correlation analysis (CCA).

METHODS

Baseline data from 9093 participants from the Adolescent Brain Cognitive Development (ABCD) Study were examined using CCA, a multivariate statistical approach that identifies many-to-many associations between two sets of variables by finding combinations for each set of variables that maximize their correlation. We combined CCA with leave-one-site-out cross-validation across ABCD sites to examine the robustness of results and generalizability to new participants. The statistical significance of canonical correlations was determined by non-parametric permutation tests that accounted for twin, family, and site structure. To assess the stability of the associations identified at baseline, CCA was repeated using 2-year follow-up data from 4247 ABCD Study participants.

RESULTS

Two significant sets of associations were identified: (1) difficulty initiating and maintaining sleep and excessive daytime somnolence were strongly linked to nearly all domains of psychopathology (r2 = 0.36, p < .0001); (2) sleep breathing disorders were linked to BMI and African American/black race (r2 = 0.08, p < .0001). These associations generalized to unseen participants at all 22 ABCD sites and were replicated using 2-year follow-up data.

CONCLUSIONS

These findings underscore interwoven links between sleep disturbances in early adolescence and psychological, social, and demographic factors.

Time use and dimensions of healthy sleep: A cross-sectional study of Australian children and adults

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 12years; 49% female) and 1360 adults (mean age 44years; 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.

Evaluating Sleep Challenges in Hospitalized Youth

OBJECTIVE

To characterize sleep quality and sleep disruptions among youth hospitalized outside of the intensive care unit (ICU).

PATIENTS AND METHODS

Participants were eligible for the survey-based study if they were 8-17 years old, English-speaking, hospitalized for ≥3 days outside of the ICU, and developmentally able to understand surveys. Survey administration included a sleep diary, the Epworth Sleepiness Scale for Children and Adolescents (ESS-CHAD), and a study-specific Inpatient Sleep Disruptors Questionnaire. The chart review provided additional clinical information. Descriptive and comparative statistics were performed to assess the association between overnight clinical monitoring and daytime sleepiness.

RESULTS

Forty-five participants (mean age 13.4 years, 60% female), recruited between May and December 2022, were included in the study. Mean total sleep time (8.2 ± 1.7 hours) and ESS-CHAD score (8.6 ± 4.3) were normal with 79% reporting fair to good sleep the previous night. Participants rated alarms on equipment, vital signs, and noise as most disruptive to sleep. Participants with vital signs every four hours showed higher levels of daytime sleepiness compared with participants with vitals measured every shift (9.3 vs. 6.3; p=0.04).

CONCLUSIONS

Most participants reported normal sleep, although there was wide variability with a portion with impaired sleep quality and elevated daytime sleepiness. Alarms on equipment, vital signs, and noise were most disruptive, and increased vital sign frequency was also associated with increased daytime sleepiness. In clinically stable pediatric patients, a reduction in vital sign monitoring overnight may be an important change to improve patient sleep.

Pioneering a Multi-Phase Framework to Harmonize Self-Reported Sleep Data Across Cohorts

STUDY OBJECTIVES

Harmonizing and aggregating data across studies enable pooled analyses that support external validation and enhance replicability and generalizability. However, the multidimensional nature of sleep poses challenges for data harmonization and aggregation. Here we describe and implement our process for harmonizing self-reported sleep data.

METHODS

We established a multi-phase framework to harmonize self-reported sleep data: (1) compile items; (2) group items into domains; (3) harmonize items; and (4) evaluate harmonizability. We applied this process to produce a pooled multi-cohort sample of five United States cohorts plus a separate yet fully harmonized sample from Rotterdam, Netherlands. Sleep and sociodemographic data are described and compared to demonstrate the utility of harmonization and aggregation.

RESULTS

We collected 190 unique self-reported sleep items and grouped them into 15 conceptual domains. Using these domains as guiderails, we developed 14 harmonized items measuring aspects of Satisfaction, Alertness/Sleepiness, Timing, Efficiency, Duration, Insomnia, and Sleep Apnea. External raters determined that 13 of these 14 items had moderate-to-high harmonizability. Alertness/Sleepiness items had lower harmonizability, while continuous, quantitative items (e.g., timing, total sleep time, efficiency) had higher harmonizability. Descriptive statistics identified features that are more consistent (e.g., wake-up time, duration) and more heterogeneous (e.g., time in bed, bedtime) across samples.

CONCLUSIONS

Our process can guide researchers and cohort stewards towards effective sleep harmonization and provides a foundation for further methodological development in this expanding field. Broader national and international initiatives promoting common data elements across cohorts are needed to enhance future harmonization and aggregation efforts.

Daytime Sleepiness from Preschool Children's and Parents' Perspectives: Is There a Difference?

This cross-sectional study investigated the level of daytime sleepiness and sleep-related behaviors in preschool children and compared their self-evaluations with the evaluations of their parents. It was conducted in Split-Dalmatian County, Croatia, among 196 preschool children aged 6-7 years seen at regular medical examinations, accompanied by their parents, using the Epworth sleepiness scale for children and parents/caregivers. Compared to their child's reports, parents tended to underestimate their child's sleepiness while sitting in a classroom at school (p = 0.001) and overestimate their child's sleepiness when lying down to rest or nap in the afternoon (p < 0.001). Boys were sleepier while sitting in a classroom at school during the morning than girls (p = 0.032). As much as 48.2% of preschool children had their own cellphones/tablets. Boys used video games (p < 0.001) and cellphones/tablets more than girls did (p = 0.064). Parental estimation of children playing video games at bedtime was lower than the child's report (p < 0.001). Children who had a TV in their bedroom reported more daytime sleepiness (p = 0.049), and those who played video games at bedtime went to sleep later during the weekend (p = 0.024). Also, children owning cellphone/tablets had longer sleep latency during the weekend compared to children not owning a cellphone (p = 0.015). This study confirmed that parents tend to underestimate children's habits of playing video games at bedtime and children's sleepiness during morning classes. Preschool children who use electronic devices at bedtime more frequently have prolonged sleep latency. These findings provide further evidence of the effects of electronic media devices on preschoolers' sleep patterns and daytime sleepiness.

Development of the Parenting Behavior Checklist to Promote Preschoolers' Sleep (PCPP)

OBJECTIVES

To develop the Parenting Behavior Checklist to Promote Preschoolers' sleep (PCPP), quantify sleep-promoting parenting behaviors for children, and examine the scale's reliability and validity.

METHODS

The PCPP was developed based on the recommendations of the ABCs of SLEEPING for children's sleep, which is strongly supported by research evidence. Its validity and reliability were evaluated using data from 140 participants. Structural validity was estimated using exploratory factor analysis (EFA) and confirmatory factor analysis (CFA), and internal consistency was evaluated by Cronbach's α. Hypothesis testing was evaluated by analyzing the correlations between each factor of the Japanese Sleep Questionnaire for Preschoolers (JSQ-P) and the PCPP.

RESULTS

Regarding structural validity, EFA was conducted because CFA showed a poor model fit. The PCPP comprised one factor and six items. The JSQ-P subfactors of insomnia or circadian rhythm sleep-wake disorders, undesirable morning symptoms and behaviors, and insufficient sleep were moderately negatively correlated with the PCPP; the subfactor of undesirable daytime behaviors related to sleep problems was weakly negatively correlated with the PCPP. Thus, the sleep-promoting parenting behaviors listed in the PCPP were associated with better sleep in children.

CONCLUSIONS

The PCPP showed sufficient reliability and validity. Future studies should use the scale to examine more effective interventions regarding sleep-promoting parental behaviors for children.

Associations between sleep and appetitive traits in higher-income preschoolers: A six-month study

BACKGROUND

Short sleep is consistently linked with childhood obesity, possibly via disrupting appetite hormones and increasing food responsiveness. Few studies have objectively examined this association in early childhood.

OBJECTIVE

To evaluate associations of sleep quantity and quality with child appetitive traits and eating in the absence of hunger (EAH) in a higher-income cohort of 86 preschool-age children (age 4.0 ± 0.8 years; 42% female; 93% non-Hispanic white, Northern New England, US).

METHODS

Children's sleep duration and quality were assessed via parent report (Children's Sleep Habits Questionnaire, CSHQ) at baseline and 6-month follow-up and via accelerometry at baseline. Parents also completed the Child Eating Behaviors Questionnaire to assess the child's appetitive traits. EAH, an objective measure of overeating, was observed at baseline during an in-person visit. Associations between sleep measures and appetitive traits were examined with linear mixed-effect or linear regression models, as appropriate, adjusting for child age, sex, and household income.

RESULTS

Shorter sleep duration per parent report was associated with less satiety responsiveness (standardized ß = 0.14, 95% CI: 0.01, 0.26; p = 0.03). Further, satiety responsiveness was inversely related to EAH (Pearson's r = -0.35, p = 0.02). No associations were found between accelerometer-measured sleep parameters and appetitive traits, and no sleep measures were related to EAH.

CONCLUSIONS

Shorter usual sleep, per the parent report, was cross-sectionally associated with reduced satiety responsiveness in this sample of higher-income preschoolers. Future studies should consider whether socioeconomic status may modify the impact of poor sleep on appetitive traits in early childhood.

Pediatric Occupational Therapists' Perspectives on Sleep: A Qualitative Descriptive Study

IMPORTANCE

Insufficient sleep is common among children seeking occupational therapy services but is rarely a focus of therapy despite sleep's critical impact on health.

OBJECTIVE

To examine pediatric occupational therapists' experiences, views, and confidence in addressing sleep concerns in their practice as well as barriers to and supports for doing so.

DESIGN

A qualitative descriptive study with thematic analysis of data from 1-hr virtual interviews. Rapport building, multiple-coder analysis, and member checking were used to ensure reliability and validity.

SETTING

Interviews were conducted remotely at each participant's preferred time and location.

PARTICIPANTS

Pediatric occupational therapists (N = 20) practicing across multiple settings in the United States were recruited through emails directed to their place of work and social media posts. A goal of 20 participants was set a priori with the goal of thematic saturation.

OUTCOMES AND MEASURES

A semistructured interview guide.

RESULTS

Participants were predominately cisgender (95%), female (85%), and White, non-Hispanic (90%). Overall, they voiced the importance of sleep but reported almost never writing sleep-related goals. Reported barriers that affected the participants' ability to fully address sleep in practice included therapists' lack of confidence and knowledge and low caregiver buy-in.

CONCLUSIONS AND RELEVANCE

The findings identify themes on the basis of which actionable steps toward promoting occupational therapists as sleep champions can be developed. Future implications include increasing sleep education opportunities, enhancing awareness of sleep health's impact on goal areas, and facilitating discussions about occupational therapy's role within the medical system and family system in supporting sleep. Plain-Language Summary: This qualitative study identifies what helps and hinders occupational therapists in addressing the sleep health concerns of their clients. We give occupational therapy clinicians and educators key supports to seek out or barriers to address.

Sleep Habits, Academic Performance and Health Behaviors of Adolescents in Southern Greece

Adolescents often experience insufficient sleep and have unhealthy sleep habits. Our aim was to investigate the sleep patterns of secondary education students in Heraklion, Crete, Greece and their association with school performance and health habits. We conducted a community-based cross-sectional study with 831 students aged 13-19 years who completed an online self-reported questionnaire related to sleep and health habits. The data are mostly numerical or categorical, and an analysis was performed using t-tests, chi-square tests and multiple logistic regression. During weekdays, the students slept for an average of 7 ± 1.1 h, which is significantly lower than the 7.8 ± 1.5 h average on weekends (p < 0.001). Nearly 79% reported difficulty waking up and having insufficient sleep time, while 73.8% felt sleepy at school at least once a week. Having sufficient sleep time ≥ 8 h) was positively correlated with better academic performance (OR: 1.48, CI: 1.06-2.07, p = 0.022) and frequent physical exercise (never/rarely: 13.5%, sometimes: 21.2%, often: 65.3%; p = 0.002). Conversely, there was a negative correlation between adequate sleep and both smoking (OR: 0.29, CI: 0.13-0.63) and alcohol consumption (OR: 0.51, CI: 0.36-0.71, p = 0.001). In conclusion, this study shows that students in Heraklion, Crete frequently experience sleep deprivation, which is associated with compromised academic performance, reduced physical activity and an increased likelihood of engaging in unhealthy behaviors like smoking and alcohol consumption.

The Indirect Effect of Sleep Quality on Stress-Related Psychosocial Outcomes in Adolescents: An Investigation Across Genders

Sleep is foundational for adolescent psychosocial outcomes though often compromised by normative developmental changes and external factors. This cross-sectional study examined sleep quality as a mechanism linking stress and psychosocial outcomes and explored gender differences. Adolescents (N = 246; Mage=15.8; 46.3% female) completed self-report measures assessing sleep quality and psychosocial outcomes. Structural equation modeling results indicated sleep quality accounted for 78.4% of the total effect of stress on school functioning (b=-0.45, p < 0.001) and 54.2% of the total effect of stress on pain (b = 0.14, p = 0.002). A larger indirect effect of sleep quality on school functioning (b=-0.26, p = 0.016) emerged for boys than girls, and the effect of sleep quality on pain was significant only for girls (b = 0.18, p < 0.001, 69.6% of total effect). Sleep quality explained a large proportion of the effect of stress on school functioning and pain. Sleep quality represents a modifiable transdiagnostic pathway that may buffer the effects of stress in adolescence.

Evaluation of the association between excessive screen use, sleep patterns and behavioral and cognitive aspects in preschool population. A systematic review

In this review, we analyzed the possible relationship between the excessive use of screens and sleep patterns, and how this may affect certain behavioral and cognitive factors in preschool children. The selection, extraction and synthesis of the data were conducted according to PRISMA guidelines. The search was carried out in the electronic databases Medline (PubMed), PsycINFO (American Psychological Association), Scopus and Web of Science (WOS). Of the 597 articles initially identified, 13 met the inclusion criteria. The risk of bias of the articles selected was evaluated using a specific scale created for this purpose. The results found indicate that excessive use of screens is associated with a negative impact on the duration and quality of sleep-in preschoolers, and this worsening of sleep in infancy is related with a greater probability of the appearance of internalizing and externalizing behavioral problems and certain cognitive problems. The results also suggest that sleep could play a mediating or moderating role as a bioregulatory system that attenuates or increases the onset of behavioral and cognitive difficulties in those children most exposed to digital devices.

Understanding risk and causal mechanisms for developing obesity in infants and young children: A National Institutes of Health workshop

Obesity in children remains a major public health problem, with the current prevalence in youth ages 2-19 years estimated to be 19.7%. Despite progress in identifying risk factors, current models do not accurately predict development of obesity in early childhood. There is also substantial individual variability in response to a given intervention that is not well understood. On April 29-30, 2021, the National Institutes of Health convened a virtual workshop on "Understanding Risk and Causal Mechanisms for Developing Obesity in Infants and Young Children." The workshop brought together scientists from diverse disciplines to discuss (1) what is known regarding epidemiology and underlying biological and behavioral mechanisms for rapid weight gain and development of obesity and (2) what new approaches can improve risk prediction and gain novel insights into causes of obesity in early life. Participants identified gaps and opportunities for future research to advance understanding of risk and underlying mechanisms for development of obesity in early life. It was emphasized that future studies will require multi-disciplinary efforts across basic, behavioral, and clinical sciences. An exposome framework is needed to elucidate how behavioral, biological, and environmental risk factors interact. Use of novel statistical methods may provide greater insights into causal mechanisms.

Predictors for achieving optimal sleep in healthy children: Exploring sleep patterns in a sleep extension trial

STUDY OBJECTIVES

Earlier bedtimes can help some children get more sleep, but we don't know which children, or what features of their usual sleep patterns could predict success with this approach. Using data from a randomized crossover trial of sleep manipulation, we sought to determine this.

METHODS

Participants were 99 children aged 8-12years (49.5% female) with no sleep disturbances. Sleep was measured by actigraphy at baseline and over a restriction or extension week (1 hour later or earlier bedtime respectively), randomly allocated and separated by a washout week. Data were compared between baseline (week 1) and extension weeks only (week 3 or 5), using linear or logistic regression analyses as appropriate, controlling for randomization order.

RESULTS

One hour less total sleep time than average at baseline predicted 29.7 minutes (95% CI: 19.4, 40.1) of sleep gained and 3.45 (95% CI: 1.74, 6.81) times higher odds of successfully extending sleep by >30 minutes. Per standardized variable, less total sleep time and a shorter sleep period time were the strongest predictors (significant odds ratios (ORs) of 2.51 and 2.28, respectively). Later sleep offset, more variability in sleep timing and lower sleep efficiency also predicted sleep gains. The sleep period time cut-point that optimized prediction of successful sleep gains was <8 hours 28 minutes with 75% of children's baseline sleep in that range.

CONCLUSIONS

Children with a baseline sleep period time <8½ hours a night obtained the most sleep from earlier bedtimes maintained over a week, demonstrating experimentally the value of earlier bedtimes to improve sleep.

The associations between instructional approach, sleep characteristics and adolescent mental health: Lessons from the COVID-19 pandemic

OBJECTIVES

To test whether adolescents' mental health during the COVID-19 pandemic is associated with the combination of their instructional approach(es) and their sleep patterns.

DESIGN

Cross-sectional.

SETTING

Adolescents were recruited through social media outlets in October and November 2020 to complete an online survey.

PARTICIPANTS

Participants were 4442 geographically and racially diverse, community-dwelling students (grades 6-12, 51% female, 36% non-White, 87% high schoolers).

MEASUREMENTS

Participants completed items from the PROMIS Pediatric Depressive Symptoms and Anxiety scales. Participants reported their instructional approach(es), bedtimes, and wake times for each day in the past week. Participants were categorized into five combined instructional approach groups. Average sleep opportunity was calculated as the average time between bedtime and waketime. Social jetlag was calculated as the difference between the average sleep midpoint preceding non-scheduled and scheduled days.

RESULTS

Emotional distress was elevated in this sample, with a large proportion of adolescents reporting moderate-severe (T-score ≥ 65) levels of depressive symptoms (49%) and anxiety (28%). There were significant differences between instructional approach groups, such that adolescents attending all schooldays in-person reported the lowest depressive symptom and anxiety T-scores (P < .001, ηp2 = .012), but also the shortest sleep opportunity (P < .001, ηp2 = .077) and greatest social jetlag (P < .001, ηp2 = .037) of all groups. Adolescents attending school in person, with sufficient sleep opportunity (≥8-9 hours/night) and limited social jetlag (<2 hours) had significantly lower depressive (ηp2 = .014) and anxiety (ηp2 = .008) T-scores than other adolescents.

CONCLUSIONS

Prioritizing in-person education and promoting healthy sleep patterns (more sleep opportunity, more consistent sleep schedules) may help bolster adolescent mental health.

Substituting Book Reading for Screen Time Benefits Preschoolers' Sleep Health: Results from the Ulm SPATZ Health Study

Purpose

Healthy sleep is essential for the physical, cognitive, and social development of children. Several studies have reported the increase in digital media use in preschool children and its association with impaired sleep. However, there is relatively little evidence on the effects of book reading as a potentially safe alternative. The objective of this study, therefore, was to investigate whether sleep in children could benefit from book reading, and whether the negative effects of media use on sleep can be mitigated by substituting book reading for screen time.

Participants and Methods

We used longitudinal data from three consecutive waves of the SPATZ Health study, including children at the ages of 4 (n=581), 5 (n=508), and 6 (n=426) years. All data were collected by self-administered questionnaires. Parent-reported child sleep was assessed by the Children's Sleep Habits Questionnaire.

Results

Across the three waves, screen-based media use increased and was associated with lower sleep quality. In contrast, the time spent with book reading decreased; however, book reading appeared to be beneficial for children's sleep. Substitution models revealed that the theoretical substitution of an equal amount of book reading for 50% of the time spent with screen-based media benefits several domains of preschoolers' sleep health, including parasomnias, sleep anxiety, daytime sleepiness, and sleep onset delay.

Conclusion

Besides implications for population-wide and individual prevention, book reading may also be incorporated as a useful intervention to improve sleep quality in children who are already affected by sleep problems. Given that book reading is perceived as a safe alternative, the presented evidence may suffice to support recommendations in this direction.

Sleep-Related Predictors of Risk for Alcohol Use and Related Problems in Adolescents and Young Adults

PURPOSE

Growing evidence supports sleep and circadian rhythms as influencing alcohol use and the course of alcohol use disorder (AUD). Studying sleep/circadian-alcohol associations during adolescence and young adulthood may be valuable for identifying sleep/circadian-related approaches to preventing and/or treating AUD. This paper reviews current evidence for prospective associations between sleep/circadian factors and alcohol involvement during adolescence and young adulthood with an emphasis on the effects of sleep/circadian factors on alcohol use.

SEARCH METHODS

The authors conducted a literature search in PsycInfo, PubMed, and Web of Science using the search terms "sleep" and "alcohol" paired with "adolescent" or "adolescence" or "young adult" or "emerging adult," focusing on the title/abstract fields, and restricting to English-language articles. Next, the search was narrowed to articles with a prospective/longitudinal or experimental design, a sleep-related measure as a predictor, an alcohol-related measure as an outcome, and confirming a primarily adolescent and/or young adult sample. This step was completed by a joint review of candidate article abstracts by two of the authors.

SEARCH RESULTS

The initial search resulted in 720 articles. After review of the abstracts, the list was narrowed to 27 articles reporting on observational longitudinal studies and three articles reporting on intervention trials. Noted for potential inclusion were 35 additional articles that reported on studies with alcohol-related predictors and sleep-related outcomes, and/or reported on candidate moderators or mediators of sleep-alcohol associations. Additional articles were identified via review of relevant article reference lists and prior exposure based on the authors' previous work in this area.

DISCUSSION AND CONCLUSIONS

Overall, the review supports a range of sleep/circadian characteristics during adolescence and young adulthood predicting the development of alcohol use and/or alcohol-related problems. Although sleep treatment studies in adolescents and young adults engaging in regular and/or heavy drinking show that sleep can be improved in those individuals, as well as potentially reducing alcohol craving and alcohol-related consequences, no studies in any age group have yet demonstrated that improving sleep reduces drinking behavior. Notable limitations include relatively few longitudinal studies and only two experimental studies, insufficient consideration of different assessment timescales (e.g., day-to-day vs. years), insufficient consideration of the multidimensional nature of sleep, a paucity of objective measures of sleep and circadian rhythms, and insufficient consideration of how demographic variables may influence sleep/circadian-alcohol associations. Examining such moderators, particularly those related to minoritized identities, as well as further investigation of putative mechanistic pathways linking sleep/circadian characteristics to alcohol outcomes, are important next steps.

Associations of sleep time, quality of life, and obesity indicators on physical literacy components: a structural equation model

AIM

To verify the association between ideal sleep time and physical literacy components while also considering multiple mediators, such as quality of life and obesity, using a sample of adolescents.

METHODS

This cross-sectional study consisted of 470 adolescents aged 11-17 years from southern Brazil. Sleep time, health-related quality of life, and physical literacy components (i.e., physical education enjoyment, sports participation, sedentary behavior, moderate to vigorous physical activity, sex, and age) were evaluated through self-reported questionnaires. In addition, body mass index (BMI), and waist circumference were determined. The theoretical/statistical support of the structural equation model was evaluated according to fit parameters and strength of association.

RESULTS

A direct association was observed between more sleep time and lower levels of obesity. The obesity indicators also had a negative association with HqOL, and HqOL had a positive association with physical literacy. The indirect associations indicated that the ideal sleep time was positively associated with HqOL and physical literacy components, considering the negative mediation effect of obesity. The model explains physical literacy in 31% of the variance (R = 0.31).

CONCLUSION

There was an indirect association between ideal sleep duration and quality of life and between both variables with physical literacy. These relationships occur even considering the negative influence of obesity. Therefore, a child who sleeps adequately has a higher likelihood of being physically active, regardless of obesity, potentially enhancing overall quality of life across various domains.

Association of sleep timing and sleep variability with health-related outcomes in a sample of Brazilian adolescents

OBJECTIVES

This cross-sectional study aimed to examine the relationships of sleep timing and sleep variability with depressive symptoms, health-related quality of life (HRQoL), daytime sleepiness, and body mass index (BMI) in adolescents.

METHODS

Adolescents from three schools (n = 571, 56% female, 16.3 ± 1.0 years) had their sleep examined by actigraphy, their anthropometrics assessed, and answered a survey. Sleep timing was examined by combining groups of median-dichotomized onset and wakeup times (early onset and early wakeup; early onset and late wakeup; later onset and early wakeup; later onset and later wakeup); sleep variability was based on within-participant standard deviations of onset and wakeup; and sleep duration as the length of time between onset and wakeup. The sleep variables were separated for weekdays and weekend. Mixed linear models were fitted to compare each sleep variable with health-related outcomes.

RESULTS

Higher values of daytime sleepiness were observed in adolescents from the late-early and late-late timing group during the week. Greater sleep midpoint and wakeup variability on weekdays were related with higher daytime sleepiness. Adolescents in the late-late and early-late groups showed higher daytime sleepiness. Increased of all sleep variability variables was related with greater daytime sleepiness. Higher depressive symptoms scores were found among adolescents in the late-early subgroup and with the increase of sleep variability. Participants with greater sleep onset variability and sleep midpoint variability reported less HRQoL.

CONCLUSIONS

Not only sleep duration, but sleep timing and variability also relate to health outcomes, and should be addressed by policies and interventions among adolescents.

Trying to Do What's Best: Maternal Perspectives About Toddler Sleep Health Among an Underresourced Sample of Mothers With Diverse Racial and Ethnic Identities

INTRODUCTION

This study describes mothers' knowledge, attitudes, beliefs, and practices about their toddler's sleep health among an underresourced sample of mothers with diverse racial and ethnic identities.

METHOD

This was a descriptive qualitative study with 16 mothers and their 12- to 36-month-old child. Mothers completed a semistructured, audio-recorded interview about their toddler's sleep health. Data were analyzed using inductive content analysis on the basis of established methods.

RESULTS

Mothers self-identified as 18.8% Black, 43.8% White, 12.5% multiracial, 25.0% other race, and 37.5% Hispanic. Of the mothers, 80.0% reported a past year household income of ≤ $40,000. A core construct, "Trying to do What's Best," emerged from the interview data, and this construct included three domains: Getting Good Sleep, Getting Thrown Off, and Rolling With It.

DISCUSSION

Findings support future strengths-based and multilevel sleep health-promoting interventions.

Artificial intelligence in paediatrics: Current events and challenges

This article examines the use of artificial intelligence (AI) in the field of paediatric care within the framework of the 7P medicine model (Predictive, Preventive, Personalized, Precise, Participatory, Peripheral and Polyprofessional). It highlights various applications of AI in the diagnosis, treatment and management of paediatric diseases as well as the role of AI in prevention and in the efficient management of health care resources and the resulting impact on the sustainability of public health systems. Successful cases of the application of AI in the paediatric care setting are presented, placing emphasis on the need to move towards a 7P health care model. Artificial intelligence is revolutionizing society at large and has a great potential for significantly improving paediatric care.

Caffeine intake and its association with nutrition, sleep, and physical activity among schoolchildren in the United Arab Emirates: a national cross-sectional study

PURPOSE

Recent surveys indicate a significant increase in total caffeine intake among schoolchildren. Limited research has been published concerning the total intake of caffeine among schoolchildren in the Middle East and Gulf Cooperation Council (GCC) countries, including the UAE.

METHODS

This cross-sectional survey estimated the total caffeine intake from foods and beverages among 10,275 schoolchildren in the UAE. Caffeine intakes were related to the European Food Safety Authority's level of no safety concern (3.0 mg/kg BW) and level of effects on sleep (1.4 mg/kg BW).

RESULTS

More than half (56.2%) of the students consumed more than 100 mg (the upper limit allowed) of caffeine from dietary sources. High intake of caffeine (> 100 mg/day) was significantly associated (p = 0.001) with reduced sleep duration, difficulty falling asleep, infrequent exercising, using smart devices for more than 2 h a day, getting a lower GPA, skipping breakfast, eating fewer servings of vegetables than recommended, frequent consumption of fast food and more frequent snack consumption.

CONCLUSION

Excessive intake of caffeine from different dietary sources coexists with unhealthy dietary and lifestyle behaviors and sleep problems. Tailoring educational programs and intervention strategies is warranted to correct the unhealthy intake of caffeine and the associated unhealthy dietary and lifestyle behaviors among schoolchildren in the UAE.

Machine learning data sources in pediatric sleep research: assessing racial/ethnic differences in electronic health record-based clinical notes prior to model training

Introduction

Pediatric sleep problems can be detected across racial/ethnic subpopulations in primary care settings. However, the electronic health record (EHR) data documentation that describes patients' sleep problems may be inherently biased due to both historical biases and informed presence. This study assessed racial/ethnic differences in natural language processing (NLP) training data (e.g., pediatric sleep-related keywords in primary care clinical notes) prior to model training.

Methods

We used a predefined keyword features set containing 178 Peds B-SATED keywords. We then queried all the clinical notes from patients seen in pediatric primary care between the ages of 5 and 18 from January 2018 to December 2021. A least absolute shrinkage and selection operator (LASSO) regression model was used to investigate whether there were racial/ethnic differences in the documentation of Peds B-SATED keywords. Then, mixed-effects logistic regression was used to determine whether the odds of the presence of global Peds B-SATED dimensions also differed across racial/ethnic subpopulations.

Results

Using both LASSO and multilevel modeling approaches, the current study found that there were racial/ethnic differences in providers' documentation of Peds B-SATED keywords and global dimensions. In addition, the most frequently documented Peds B-SATED keyword rankings qualitatively differed across racial/ethnic subpopulations.

Conclusion

This study revealed providers' differential patterns of documenting Peds B-SATED keywords and global dimensions that may account for the under-detection of pediatric sleep problems among racial/ethnic subpopulations. In research, these findings have important implications for the equitable clinical documentation of sleep problems in pediatric primary care settings and extend prior retrospective work in pediatric sleep specialty settings.

Improving adolescent sleep in long-term Juvenile correctional settings: case examples with clinical, research, and policy implications

Poor sleep during adolescence is a public health concern that may be especially important to address among youth in juvenile correctional facilities, who tend to experience greater mental health challenges, substance use disorders, and traumatic stress exposure. However, evidence for addressing sleep in correctional settings is limited. Using de-identified composite clinical cases, this paper describes challenges and opportunities for addressing sleep disorders (i.e. insomnia) and promoting sleep health (i.e. improving duration, regularity, and behaviors) among adolescents in long-term juvenile correctional facilities. These clinical cases highlight common presenting problems and underscore the need for integrated sleep and mental health interventions as well as adaptations to enhance feasibility and efficacy of behavioral sleep treatment and sleep health promotion in juvenile correctional contexts. We conclude by summarizing clinical, research, and policy implications for addressing adolescent sleep problems and promoting sleep health and well-being in these contexts.

Childhood sleep: physical, cognitive, and behavioral consequences and implications

BACKGROUND

Sleep problems in children have been increasingly recognized as a major public health issue. Previous research has extensively studied and presented many risk factors and potential mechanisms for children's sleep problems. In this paper, we aimed to identify and summarize the consequences and implications of child sleep problems.

DATA SOURCES

A comprehensive search for relevant English language full-text, peer-reviewed publications was performed focusing on pediatric sleep studies from prenatal to childhood and adolescence in a variety of indexes in PubMed, SCOPUS, and Psych Info published in the past two decades. Both relevant data-based articles and systematic reviews are included.

RESULTS

Many adverse consequences are associated with child sleep deficiency and other sleep problems, including physical outcomes (e.g., obesity), neurocognitive outcomes (e.g., memory and attention, intelligence, academic performance), and emotional and behavioral outcomes (e.g., internalizing/externalizing behaviors, behavioral disorders). Current prevention and intervention approaches to address childhood sleep problems include nutrition, exercise, cognitive-behavioral therapy for insomnia, aromatherapy, acupressure, and mindfulness. These interventions may be particularly important in the context of coronavirus disease 2019. Specific research and policy strategies can target the risk factors of child sleep as well as the efficacy and accessibility of treatments.

CONCLUSIONS

Given the increasing prevalence of child sleep problems, which have been shown to affect children's physical and neurobehavioral wellbeing, understanding the multi-aspect consequences and intervention programs for childhood sleep is important to inform future research direction as well as a public health practice for sleep screening and intervention, thus improving sleep-related child development and health.

Assessing sleep behaviors in Latino children and adolescents: what is known, what are we missing, and how do we move forward?

PURPOSE OF REVIEW

Sleep health is a commonly overlooked component of pediatric cardiometabolic risk. Disparities in sleep duration and meeting of pediatric sleep guidelines have been well documented among at-risk populations in the United States, including Latinos. However, sleep research often fails to describe or account for contextual and cultural factors impacting the ability for Latino families to meet guidelines. The current review focuses on recent findings related to measurement of sleep duration, understanding of contextual factors that impact sleep hygiene, and interventions designed to increase sleep duration and quality among U.S. Latino families with infants, young children, and adolescents.

RECENT FINDINGS

Ten studies focusing on sleep health in U.S. Latino children, using different study designs were identified. Overall, cross-sectional studies confirmed inadequate sleep among Latino children, intervention studies demonstrated promise of culturally-sensitive health behavior education for improving sleep in early childhood, and qualitative studies highlighted neighborhood and cultural factors that impact sleep quality.

IMPLICATIONS FOR CLINICAL PRACTICE AND RESEARCH

Rather than new prevalence studies on adherence to sleep recommendations among Latino families, research focusing on adapting clinical guidelines to accommodate the realities of many Latino families (e.g., co-sleeping and bedsharing) will advance our knowledge. A shift towards objective measurement of the 24-h period as well as evaluating specific contextual barriers that make It challenging to meet sleep guidelines for Latino children is needed.

Early adverse childhood experiences and adolescent sleep outcomes

BACKGROUND

Sleep is critical for physical, mental, and emotional health. This may be particularly true for adolescents experiencing rapid physiological changes. Relatively little is known about how adverse childhood experiences (ACEs) are implicated in adolescent experiences with sleep.

OBJECTIVE

We use data (from the Future of Families and Child Wellbeing Study (FFCWS, n = 3444) to assess the relationship between early ACE exposure (by age 5) and various adolescent sleep outcomes. We anticipate that early ACEs will be associated with poor adolescent sleep outcomes.

METHODS

FFCWS data includes survey responses from parents and/or primary caregivers and children at birth and approximately one, three, five, nine, and 15 years later. The FFCWS oversampled unmarried parents with low educational attainment, income, and from marginalized racial-ethnic groups. Models of sleep outcomes included ordinary least squares, Poisson, negative binomial, logistic, and order logistic regression, as appropriate.

RESULTS

Despite a high number of ACEs, adolescent hours of sleep were consistent with published recommendations. Other measures of sleep indicated adolescents in the sample experience worse sleep on most other measures. ACE exposure was associated with difficulty falling asleep and staying asleep. More ACEs was also related with problematic sleep environments (i.e., place slept) and increased snoring. There was some evidence that ACEs were related to less sleep on weekends and increased social jet lag (different patterns of sleep between weekdays and weekends).

CONCLUSIONS

Our findings suggest that ACEs could be important diagnostic data for clinicians in primary care and behavioral sleep medicine practice.

Ethical considerations in using sensors to remotely assess pediatric health behaviors

Sensors, including accelerometer-based and electronic adherence monitoring devices, have transformed health data collection. Sensors allow for unobtrusive, real-time sampling of health behaviors that relate to psychological health, including sleep, physical activity, and medication-taking. These technical strengths have captured scholarly attention, with far less discussion about the level of human touch involved in implementing sensors. Researchers face several subjective decision points when collecting health data via sensors, with these decisions posing ethical concerns for users and the public at large. Using examples from pediatric sleep, physical activity, and medication adherence research, we pose critical ethical questions, practical dilemmas, and guidance for implementing health-based sensors. We focus on youth given that they are often deemed the ideal population for digital health approaches but have unique technology-related vulnerabilities and preferences. Ethical considerations are organized according to Belmont principles of respect for persons (e.g., when sensor-based data are valued above the subjective lived experiences of youth and their families), beneficence (e.g., with sensor data management and sharing), and justice (e.g., with sensor access and acceptability among minoritized pediatric populations). Recommendations include the need to increase transparency about the extent of subjective decision making with sensor data management. Without greater attention to the human factors involved in sensor research, ethical risks could outweigh the scientific promise of sensors, thereby negating their potential role in improving child health and care.

Sleep Disturbances and Hygiene of Adolescent Female Survivors of Domestic Minor Sex Trafficking

INTRODUCTION

This cross-sectional quantitative study investigated the sleep hygiene and disturbances of adolescent female survivors of domestic minor sex trafficking (DMST) compared to an online sample of community-dwelling adolescent females.

METHOD

Community-dwelling adolescent females (aged 13-17 years, n = 61) and survivors of DMST housed in residental care (aged 12-17 years, n = 19) completed the Children's Report of Sleep Patterns (adolescent version). Descriptive statistics on sleep health in both samples were computed and compared using chi-square and t-tests.

RESULTS

Among the survivors of DMST, the majority reported insufficient sleep duration, okay-to-poor sleep quality, waking thirsty, and frequent nightmares. Compared with community-dwelling adolescents, survivors of DMST had more symptoms of insomnia, sleepiness, nightmares, and waking thirsty (p < .05).

DISCUSSION

Sleep disturbances among adolescent female survivors of DMST may be more prevalent than in community-dwelling adolescent females. Further empirical research on appropriate assessment and trauma-informed treatment of sleep in this population is needed.

Neighborhood predictors of short sleep duration and bedtime irregularity among children in the United States: results from the 2019-2020 National Survey of Children's Health

BACKGROUND

Environmental factors may contribute to short sleep duration and irregular bedtime in children. Neighborhood factors and children's sleep duration and bedtime regularity remain a less investigated area. The aim of this study was to investigate the national and state-level proportions of children with short sleep duration and irregular bedtime and their neighborhood predictors.

METHODS

A total of 67,598 children whose parents completed the National Survey of Children's Health in 2019-2020 were included in the analysis. Survey-weighted Poisson regression was used to explore the neighborhood predictors of children's short sleep duration and irregular bedtime.

RESULTS

The prevalence of short sleep duration and irregular bedtime among children in the United States (US) was 34.6% [95% confidence interval (CI) = 33.8%-35.4%] and 16.4% (95% CI = 15.6%-17.2%) in 2019-2020, respectively. Safe neighborhoods, supportive neighborhoods, and neighborhoods with amenities were found to be protective factors against children's short sleep duration, with risk ratios ranging between 0.92 and 0.94, P < 0.05. Neighborhoods with detracting elements were associated with an increased risk of short sleep duration [risk ratio (RR) = 1.06, 95% CI = 1.00-1.12] and irregular bedtime (RR = 1.15, 95% CI = 1.03-1.28). Child race/ethnicity moderated the relationship between neighborhood with amenities and short sleep duration.

CONCLUSIONS

Insufficient sleep duration and irregular bedtime were highly prevalent among US children. A favorable neighborhood environment can decrease children's risk of short sleep duration and irregular bedtime. Improving the neighborhood environment has implications for children's sleep health, especially for children from minority racial/ethnic groups.

Attentional Control Accounts for the Association Between Anxiety Sensitivity and Sleep Efficiency in Clinic-Referred Youth

Youth with anxiety disorders report difficulty falling asleep and returning to sleep after sleep onset (i.e., poor sleep efficiency). Anxiety sensitivity, the excessive attention to physical symptoms of anxiety and their threatening interpretations, has been linked to poor sleep efficiency. We tested a conceptual model wherein attentional control, attentional focusing and attentional shifting would account for the relationship between anxiety sensitivity and poor sleep efficiency. 255 youths (6-17 years old, 78% Hispanic/Latino) who presented to a university-based research clinic completed measures on anxiety sensitivity, sleep, and attentional control. Poorer sleep efficiency was significantly correlated with higher anxiety sensitivity and lower attentional control, attentional focusing, and attentional shifting. Higher anxiety sensitivity was significantly correlated with lower attentional control and attentional focusing. Attentional control and attentional focusing, not attentional shifting, accounted for the relationship between anxiety sensitivity and poor sleep efficiency. These findings identify attentional control and attentional focusing as variables that may explain the association between anxiety sensitivity and sleep efficiency in youth.

Family income as a moderator of relations between sleep and physical health during adolescence

OBJECTIVES

Sleep duration, quality, and consistency are associated with overall physical health in adolescence, yet the effects of sleep on development may be not uniform because both sleep and physical health vary systematically along gradients of family income. To understand "for whom" sleep may be particularly beneficial, the present study tested family income as a moderator of relations between youth sleep and physical health.

METHODS

Three hundred twenty-three youth (M age=17.39years; 53% female; 41% Black, 59% White) wore wrist actigraphs for 1week at home. Four well-recognized sleep parameters were derived: minutes, efficiency, long wake episodes, and variability in minutes across the week. Parents reported family income, and mothers rated adolescents' physical health. In independent path models, physical health was regressed onto each indicator of sleep, family income, and Sleep × Family Income interactions to test potential moderation effects.

RESULTS

Associations between sleep and physical health were moderated by family income. Lower sleep efficiency, more long wake episodes, and more variability in sleep minutes were associated with poorer physical health among adolescents from lower-income families. At optimal levels of all sleep variables, income-based differences in physical health were mitigated. Youth from higher-income families tended to have better physical health regardless of their sleep.

CONCLUSIONS

Findings build evidence that sleep has relations with physical health for low-income youth in particular. Clinicians and other service providers working with youth might benefit from considering the role of sleep in prevention and interventions programs geared toward improving health.

Preliminary exploration of a multidimensional sleep health composite in adolescent females with frequent migraine

OBJECTIVE

This observational study aimed to: (i) describe and explore preliminary psychometric properties of a multidimensional sleep health composite score in adolescent females with frequent migraine; and (ii) examine associations between the composite score, headache characteristics, and emotional health.

BACKGROUND

Sleep health is a multidimensional construct comprised of various dimensions of sleep and circadian functioning, including Regularity, Satisfaction, Alertness, Timing, Efficiency, and Duration (Ru-SATED framework). The Ru-SATED sleep health composite score may provide a holistic perspective of sleep among adolescents with frequent migraine in the context of neurobiological and psychosocial impacts on sleep unique to this developmental period.

METHODS

In all, 60 female adolescents (aged 12-18 years) with high-frequency episodic or chronic migraine completed wrist-worn actigraphy for 10 days and concurrent daily electronic surveys assessing headache, sleep, and emotional health. A sleep health composite score was derived from empirically supported "healthy" versus "unhealthy" ratings on the six Ru-SATED sleep dimensions.

RESULTS

Half of participants (27/54 [50%]) had a composite score ≥4 (i.e., at least four of the six dimensions rated as poor). Convergent validity of the composite score was acceptable (rs = 0.30-0.56, all p < 0.05). Internal consistency among the dimensions was low (α = 0.45). Multivariate multiple regression models indicated that worse sleep health was associated with greater headache-related disability (B = 0.71, p = 0.018) and anxiety (B = 0.59, p = 0.010), and trended toward significance for sadness (B = 0.35, p = 0.052). The composite score was not significantly associated with headache frequency or severity.

CONCLUSIONS

A multidimensional sleep health composite score may provide an alternative, more comprehensive picture of sleep disturbance among adolescent females with frequent migraine. Larger studies are needed to examine psychometric properties more rigorously and further explore the composite score as a potentially unique predictor of headache outcomes.

Obesogenic sleep patterns among Chinese preschool children: A latent profile and transition analysis of the association sleep patterns and obesity risk

OBJECTIVE

This paper utilized a person-centered approach to examine whether sleep patterns on school and free days are associated with obesity risk in preschool children aged 3-6 years.

METHODS

The cross-sectional analysis included 204 children from the Wuhan Healthy Start Project with valid sleep data in at least four consecutive days gathered via Actigraph GT3X+. Based on three domains of sleep duration, sleep onset, and sleep offset, we used latent profile analysis to identify distinct sleep patterns on school and free days separately. Additionally, we conducted latent transition analysis to explore the probabilities of sleep patterns transitions between school and free days. The multivariate logistic regression model investigated the associations of sleep patterns with overweight/obesity (OWO) (BMI ≥ age- and sex-specific 85th percentile) and abdominal obesity (AO) (WC ≥ age- and sex-specific 75th percentile).

RESULTS

Two sleep patterns were identified for school days: "EL-sc" (early-to-sleep/longer-duration) (n = 119; 58.3%) and "LS-sc" (late-to-sleep/shorter-duration) (n = 85; 41.7%). Similarly, "LES-fr" (late-to-sleep/early-to-wake/shorter-duration) (n = 118; 57.8%) and "ELL-fr" (early-to-sleep/late-to-wake/longer-duration) (n = 86; 42.2%) patterns were identified for free days. LTA categorized the participants into four distinct transition groups, i.e., "EL-sc→ELL-fr" (32.9%), "EL-sc→LES-fr" (24.0%), "LS-sc→LES-fr" (33.8%), and "LS-sc→ELL-fr" (9.3%). Compared with the "ELsc→ELL-fr", the "LS-sc→LES-fr" had a higher risk of OWO (AOR 4.76; 95% CI: 1.39-20.33) and AO (AOR, 2.78; 95% CI, 1.21-6.62), respectively. Neither "EL-sc→LES-fr" (AOR, 1.11; 95% CI, 0.14-6.67) nor "LS-sc→ELL-fr" (AOR, 0.74; 95% CI, 0.03-6.14) was significantly associated with OWO. Likewise, no significant association was observed for "EL-sc→LES-fr" (AOR, 0.96; 95% CI, 0.35-2.62) and "LS-sc→ELL-fr" (AOR, 0.56; 95% CI, 0.11-2.18) with AO.

CONCLUSIONS

"LS-sc→LES-fr" pattern is significantly associated with an increased risk of general and abdominal obesity, indicating its obesogenic nature. Furthermore, although not statistically associated with obesity outcomes, "LS-sc→ELL-fr" and "EL-sc→LES-fr" patterns exhibit a semi-obesogenic characteristic. In addition, we identified a concerning trend that preschool children are at risk of transitioning to and persisting in sleep patterns characterized by delayed and shorter sleep. These findings underscore the importance of implementing interventions and strategies to address sleep patterns as a crucial step to minimize the risk of obesity.

Association between Sleep Timing, Being Overweight and Meal and Snack Consumption in Children and Adolescents in Southern Brazil

Sleep timing is one of the dimensions of sleep that refers to the time of day when sleep occurs. It has been included in sleep-related research because of the potential associations between being overweight and the consumption of meals and snacks. This cross-sectional study aimed to investigate associations between sleep timing, meal and snack consumption and weight status in 1333 schoolchildren aged 7-14 years. The midpoint of sleep was used as a sleep timing measure obtained by the midpoint between bedtime and wake-up time, classified as Early, Intermediate, and Late. Schoolchildren in the Early group were less likely to be overweight (OR: 0.83, 95% CI 0.69; 0.99), and had higher odds of mid-morning snack consumption (OR: 1.95, 95% CI 1.56; 2.44) and lower probability to consume an evening snack (OR: 0.75, 95% CI 0.59; 0.94) compared with the Intermediate group. The Late group had lower odds of mid-morning snack consumption (OR: 0.67, 95% CI 0.55, 0.80) than the Intermediate group. The consumption of mid-morning and evening snacks was associated with the Early and Late midpoints of sleep. These results suggest that bedtime and wake-up time are relevant to consuming meals and snacks and may also be related to a greater probability of being overweight in children and adolescents.

Sleep Problems in Pediatric Disorders of Gut-Brain Interaction: A Systematic Review

OBJECTIVE

Disorders of gut-brain interaction (DGBIs) are common, and findings are mixed on rates of sleep problems (e.g., sleep quality) in pediatric populations. A clear understanding of sleep problems in pediatric DGBIs is needed as sleep challenges might negatively impact symptoms and prognoses. The aims of this systematic review are to (1) describe the prevalence and types of sleep problems in pediatric patients with DGBIs and examine differences by DGBI diagnosis and (2) examine the relationship among sleep problems and pain, mood, and functional outcomes in pediatric patients with DGBIs.

METHODS

We searched PubMed, PsycInfo, CINAHL, and Medline in June 2022; articles were included if they enrolled ≤19 years old with a DGBI, used a quantitative assessment of sleep problems, and were available in English. The Effective Public Health Practice Project Quality Assessment Tool for Quantitative Studies was used to assess study quality. We used a protocol to systematically pull and tabulate data across articles with quality assessment ratings.

RESULTS

Twenty-four articles with 110,864 participants across 9 countries were included, with most studies being of moderate to weak quality. Patients with DGBIs reported more sleep problems than healthy peers, and some research reviewed found that patients with IBS had more sleep problems than other DGBI diagnoses. Sleep problems in DGBIs were related to worse mood, pain, and functional outcomes.

CONCLUSION

Pediatric patients with DGBIs are experiencing sleep problems that can impact outcomes. Screening for sleep problems and targeted treatment is needed to best support these patients.

A multimethod evaluation of bed provision and sleep education for young children and their families living in poverty

STUDY OBJECTIVES

We evaluated the impact of bed provision and sleep education through the Beds for Kids (BfK) program on early childhood sleep and behavior and maternal mood and sleep.

METHODS

Twenty-seven mother-child dyads (childage= 2-5 years, 85.2% Black) living in poverty and without an individual child bed were randomly assigned (multimethod randomized waitlist control trial design) to BfK intervention ∼1 week postbaseline (initial intervention) or ∼2 weeks postbaseline (waitlist control), with follow-up at 1 month. BfK intervention (home bed delivery and written sleep health education) was provided to all families. Children wore actigraphs and mothers completed daily diaries to assess child and maternal sleep, child behavior, and maternal mood for the initial 1-week comparison period. Maternal-reported child sleep and behavior (internalizing and externalizing problems) were collected at 1 month after BfK participation for all families; 11 families completed a qualitative interview at 1-month follow-up.

RESULTS

At 1 week after BfK, mothers' sleep duration increased by 1 hour compared to that of waitlist controls. No changes were found in child sleep, child behavior, or maternal mood. However, at 1 month after BfK intervention, improvements were found in mother-reported child night awakenings, sleep quality, sleep problems, and behavior. Mothers qualitatively reported significant BfK benefits for child sleep and family well-being, although they noted challenges to transitioning young children to sleeping independently.

CONCLUSIONS

Bed provision and sleep education for families living in poverty has an immediate impact on maternal sleep and reported well-being. Child sleep and behavioral improvements are seen by 1 month, with children experiencing an initial adjustment period to sleeping independently.

Defining and Promoting Pediatric Pulmonary Health: Understanding Sleep and Ventilatory Health

Healthy sleep and optimal ventilatory control begin in early development and are crucial for positive child outcomes. This paper summarizes information presented at the Sleep and Ventilatory Control sessions of the National Heart, Lung, and Blood-sponsored 2021 Defining and Promoting Pediatric Pulmonary Health workshop. These sessions focused on pediatric sleep health, screening for sleep health and sleep disorders in primary care using the electronic health record, infant sleep and ventilatory control, and home sleep testing. Throughout this summary, we discuss key gaps in and barriers to promoting sleep and ventilatory health that were identified during the workshop sessions. We conclude with strategies to address these gaps and barriers and directions for future multidisciplinary research, patient care, and training.

Sleep health behaviors in pediatric patients with newly diagnosed cancer

OBJECTIVE

Disrupted sleep and fatigue are common symptoms in children with cancer, but little is known about this population's sleep health behaviors and how they may impact nighttime sleep. We aimed to describe the sleep health behaviors of children with newly diagnosed cancer and to determine if they changed over the next 8 weeks.

METHODS

Our sample included 169 children with cancer (86 males) who were aged 2-18 years (mean [SD] = 8.14 [4.4] y), with parent proxy report for 140 children (71 male) aged 2-12 years (mean [SD] = 6.67 [3.2] y) and self-report for 78 children (39 male) aged 8-18 years (mean [SD] = 12.0 [2.9] y). Parents and patients completed sleep hygiene questionnaires within 30 days of oncology diagnosis (T1); follow-up questionnaires were collected 8 weeks later (T2). Descriptive analyses characterized the sample by sociodemographic characteristics, cancer diagnosis, treatments received, and prescribed medications.

RESULTS

Age-related differences were found in sleep health behaviors, with adolescents reporting better overall sleep health behaviors than younger children at both time points. No differences in sleep health behaviors were found at T1 related to diagnosis, treatment, or medications. Some differences in sleep health behaviors were found at T2 related to gender, diagnosis, treatment, and medications. Sleep health behaviors and sleep problems remained relatively stable over 8 weeks. Fatigue was significantly associated with more pre-bedtime worries, insomnia, and lower rates of daytime sleepiness.

CONCLUSIONS

These findings offer novel descriptive characteristics of sleep health behaviors in a pediatric oncology sample and show relatively stable yet somewhat poor sleep health behaviors across 8 weeks. Better understanding of sleep health behaviors as modifiable factors will help inform targeted interventions.
