Prevalence of diagnosed sleep disorders in pediatric primary care practices

Melatonin use in infants and toddlers

Background Melatonin use in the pediatric population is on the rise in the United States, where it is available as an over-the-counter and online supplement. There are no data regarding the safety and efficacy of melatonin in children less than 2 years old. The aim of this study was to examine various aspects of melatonin use by caregivers of infants and toddlers in the US. Methods Caregiver users of the Nanit baby monitoring system with a child aged 0-36 months were invited to complete an online survey regarding melatonin use, sources of information/recommendations about melatonin, formulations used and reasons for administering melatonin to their child. Participants also completed the Brief Infant Sleep Questionnaire-Revised (BISQ-R). Results A total of 3063 caregivers (1.93%) responded to the survey, of whom 1.7% had ever used melatonin for their child. About half of those caregivers had received a recommendation for melatonin from a source other than a healthcare professional. Caregiver perception of 'sleep as a problem' as assessed by the BISQ-R was not significantly different between those who had or had not used melatonin for their child, and reasons for use included non-supported indications such as sleeping later or promoting "more restful and better sleep". Conclusions The results of this study support mounting concerns regarding the widespread use of melatonin in the US pediatric population, especially given the lack of regulatory oversight and the documented inaccuracy of label claims versus actual melatonin content.

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.

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.

Diagnosis of sleep disorders in child healthcare settings

OBJECTIVES

Sleep disorders impact at least 10 % of children, pose risks to overall wellbeing, and are key targets of preventive interventions. The objectives of this study were to describe the prevalence of pediatric sleep disorder diagnoses across sociodemographic characteristics and co-occurring conditions, and to explore potential sociodemographic disparities.

METHODS

Cross-sectional analysis of 12,394,902 children (0-17 years; 50.9 % Medicaid-insured) in the 2017 MarketScan database. Prevalence was assessed utilizing ICD-10 codes, with multivariate logistic regressions examining disparities (insurance coverage; race and ethnicity in Medicaid-insured) for diagnoses in ≥0.10 % of children.

RESULTS

The prevalence of sleep disorder diagnoses was 2.36 %. The most common diagnoses were obstructive sleep disordered breathing (oSDB, 1.17 %), unspecified sleep disorders (0.64 %), insomnia (0.52 %), and other SDB (0.10 %), with <0.10 % for all other diagnoses. Insomnia and parasomnias diagnoses were much lower than diagnostic estimates. Sleep diagnoses were more prevalent in Medicaid versus commercially insured youth, 2-5-year-olds, and in children with co-occurring medical, neurodevelopmental, or behavioral health conditions. Girls and boys were generally equally likely to be diagnosed with any sleep disorder. In Medicaid-insured children, white children were more likely to have any sleep diagnosis compared to all other racial and ethnic groups. Black/African American children were more likely than white children to have oSDB.

CONCLUSIONS

Compared to diagnostic estimates, claims data suggest sleep disorders are under-diagnosed, with notable sociodemographic disparities. Findings suggest a need for clinical resources to identify and address sleep disorders and to understand biases potentially driving disparities, given that sleep is a modifiable determinant of child wellbeing.

Noncontact respiration monitoring techniques in young children: A scoping review

Pediatric sleep-related breathing disorders, or sleep-disordered breathing (SDB), cover a range of conditions, including obstructive sleep apnea, central sleep apnea, sleep-related hypoventilation disorders, and sleep-related hypoxemia disorder. Pediatric SDB is often underdiagnosed, potentially due to difficulties associated with performing the gold standard polysomnography in children. This scoping review aims to: (1) provide an overview of the studies reporting on safe, noncontact monitoring of respiration in young children, (2) describe the accuracy of these techniques, and (3) highlight their respective advantages and limitations. PubMed and EMBASE were searched for studies researching techniques in children <12 years old. Both quantitative data and the quality of the studies were analyzed. The evaluation of study quality was conducted using the QUADAS-2 tool. A total of 19 studies were included. Techniques could be grouped into bed-based methods, microwave radar, video, infrared (IR) cameras, and garment-embedded sensors. Most studies either measured respiratory rate (RR) or detected apneas; n = 2 aimed to do both. At present, bed-based approaches are at the forefront of research in noncontact RR monitoring in children, boasting the most sophisticated algorithms in this field. Yet, despite extensive studies, there remains no consensus on a definitive method that outperforms the rest. The accuracies reported by these studies tend to cluster within a similar range, indicating that no single technique has emerged as markedly superior. Notably, all identified methods demonstrate capability in detecting body movements and RR, with reported safety for use in children across the board. Further research into contactless alternatives should focus on cost-effectiveness, ease-of-use, and widespread availability.

Initiatives to improve lung and sleep health in children: Delphi consensus from the pediatrics, pulmonary, and sleep conference

BACKGROUND AND OBJECTIVES

The lung and sleep health of adults is heavily influenced by early factors, both genetic and environmental; therefore, optimizing respiratory health begins in childhood. Multiple barriers impede improvements in lung and sleep health for children. First, the traditional siloing between general pediatric care in the community, pediatric pulmonary and sleep subspecialty care, and the research community limits the translation of knowledge into practice. Additionally, identifying and addressing health disparities remains a challenge. The 2021 NHLBI-sponsored workshop "Defining and Promoting Pediatric Pulmonary Health (DAP3H)" was a first step in defining critical gaps in our current healthcare system in identifying and optimizing lung and sleep health in children. The workshop identified key opportunities including measuring pulmonary function in young children, sleep-focused outcomes, developing biomarkers, and longitudinal research cohorts. To expand on the work of DAP3H and continue initiatives to improve childhood lung and sleep health, the Pediatrics & Pulmonary Network: Improving Health Together conference was held in 2023.

STUDY DESIGN

A modified Delphi process was applied to form consensus surrounding gaps, barriers, and action items, with the goal of identifying the most urgent opportnities for improving childhood lung and sleep health.

RESULTS

Cross-cutting foundational principles were identified as: (1) Authentic Stakeholder Collaboration & Engagement, (2) Reach & Implementation in Real World Settings, (3) Understanding Current Landscape & Resources and (4) Purposeful Diversity, Equity, & Inclusion Initiatives.

CONCLUSIONS

To improve lung and sleep health in children, these principles should be the foundation for research design, development, and implementation.

Association between sleep disorders and health care utilization in children with chronic medical conditions: a Medicaid claims data analysis

STUDY OBJECTIVES

To examine the risk of increased health care utilization (HU) linked to individual sleep disorders in children with chronic medical conditions.

METHODS

Medicaid claims data from a cohort of 16,325 children enrolled in the Coordinated Healthcare for Complex Kids (CHECK) project were used. Sleep disorders and chronic medical conditions were identified using International Classification of Diseases, Ninth, and 10th Revision, codes. Three HU groups were identified based on participants' prior hospitalizations and emergency department (ED) visits in the 12 months prior to enrollment: low (no hospitalization or ED visit), medium (1-2 hospitalizations or 1-3 ED visits), and high (≥ 3 hospitalizations or ≥ 4 ED visits). The odds of being in an increased HU group associated with specific sleep disorders after controlling for confounding factors were examined.

RESULTS

Children with chronic medical conditions and any sleep disorder had nearly twice the odds (odds ratio = 1.83; 95% confidence interval: 1.67-2.01) of being in an increased HU group compared with those without a sleep disorder. The odds of being in the increased HU group varied among sleep disorders. Only sleep-disordered breathing (odds ratio = 1.51; 95% confidence interval : 1.17-1.95), insomnia (odds ratio = 1.46; 95% confidence interval : 1.06-2.02), and circadian rhythm sleep disorder (odds ratio = 2.45; 95% confidence interval : 1.07-5.64) increased those odds. Younger age and being White were also linked to increased HU.

CONCLUSIONS

Sleep disorders are associated with increased risk of heightened HU (ED visits and/or hospitalizations) in children with chronic medical conditions. This risk varies by specific sleep disorders. These findings indicate the need for careful evaluation and management of sleep disorders in this high-risk cohort.

Construction and Initial Examination of Inter-Rater Reliability of a Structured Clinical Interview for DSM-5-TR Sleep Disorders (SCISD) - Kid

STUDY OBJECTIVES

To construct and evaluate the inter-rater reliability of the Structured Clinical Interview for DSM-5-TR Sleep Disorders - Kid (SCISD-Kid).

METHOD

The SCISD-Kid was modeled on the adult SCISD-R and accounted for pediatric developmental and sociocultural factors. Fifty sleep-disturbed children (Mage = 11.9, SD = 2.9) and 50 caregivers responded to the final SCISD-Kid. Video recordings were double-scored to evaluate inter-rater reliability.

RESULTS

The final SCISD-Kid contained approximately 90 questions. Eight of the nine covered disorders had prevalence rates sufficient for analyses for both samples (i.e., k > 2). Inter-rater reliability was examined using Cohen kappa coefficients (κ); reliability estimates ranged from excellent to good. For youth, restless legs syndrome yielded the lowest reliability (.48), while nightmare disorder, narcolepsy, and NREM sleep arousal disorder - sleepwalking type showed the highest reliability (1.00). Across caregivers, NREM sleep arousal disorder - sleep terror type (.49) and hypersomnolence (.54) had the lowest reliability. In contrast, circadian rhythm - delayed sleep phase type, nightmare disorder, and NREM sleep arousal disorder - sleepwalking type showed the highest reliability (1.00).

CONCLUSIONS

The SCISD-Kid is a promising tool for screening sleep disorders. It showed good to excellent reliability across both samples. Next steps for validation will be discussed.

Effects of childhood obstructive sleep apnea with and without daytime sleepiness on behaviors and emotions

OBJECTIVE

To investigate the relationship between obstructive sleep apnea (OSA) with and without excessive daytime sleepiness (EDS) and behavioral and emotional outcomes in non-obese prepubertal children.

METHODS

This was a retrospective analysis of children aged 5-11 years who presented to our unit for assessment of their sleep-related complaints. All children underwent polysomnography (PSG). They also completed the Pediatric Daytime Sleepiness Scale (PDSS) and a sleep diary. OSA was diagnosed if the obstructive apnea-hypopnea index (OAHI) was ≥1 event/hour. EDS was defined as PDSS >15. Behavioral and emotional outcomes were assessed using the Child Behavioral Checklist (CBCL).

RESULTS

Data from 391 children (mean age of 8.6 ± 1.7 years; 67 % male) were analyzed. Seventy children did not have OSA or EDS, 137 had OSA, 50 had reported having EDS but without OSA, and 134 children had both OSA and EDS. There were significantly higher CBCL total problems score in the combined group (61 ± 9) compared to the non-OSA/EDS group (54 ± 10), and the OSA-only group (54 ± 10) (p < 0.001). The presence of EDS was significantly associated with higher CBCL T score and higher odds for clinically significant behavioral problems (T score ≥65) after adjusting for age, sex, BMI z-score and average sleep duration (p < 0.001).

CONCLUSION

Excessive daytime sleepiness is an important contributory factor associated with suboptimal behavioral and emotional outcomes in children with OSA.

Screening and Evaluation of Sleep Disturbances and Sleep Disorders in Children and Adolescents

Sleep disturbances and sleep disorders are prevalent in children/adolescents and have a bidirectional relationship with pediatric medical and mental health disorders. Screening tools and mechanisms for the evaluation and treatment of sleep disturbances and sleep disorders in the pediatric mental health clinic are less well-known; hence, sleep disturbances and disorders are under-recognized in the pediatric clinics. We present specific, validated screening and evaluation tools to identify sleep disturbances and sleep disorders in children/adolescents. We offer guidance related to the use of consumer wearables for sleep assessments and use of sleep telemedicine in pediatric mental health and primary care clinics.

Pediatric Insomnia

Insomnia is the most common sleep disorder among all ages; unfortunately, however, child and adolescent insomnia is infrequently addressed. Given the importance of adequate sleep for proper brain development, pediatric populations are particularly vulnerable to the negative effects of insomnia. Therefore, proper clinical assessment and treatment of pediatric insomnia is crucial. This article is the result of a comprehensive literature review and serves as a guide to the disorder and how it presents differently across child development.

Sleep disturbances in children and adolescents with type 1 diabetes mellitus: Prevalence, and relationship with diabetes management

OBJECTIVE

A decline in sleep quality and regularity has been reported in patients with type 1 diabetes mellitus (T1D) in many studies. However, research on medical-based sleep disorders in patients with T1D is limited. Diagnosing sleep disorders is crucial, as it negatively impacts academic performance, cardiovascular health, and cognitive functions among children as well as essential skills for effective diabetes management. Our objective was to assess sleep disturbances in patients diagnosed with T1D and explore whether these patients experience significantly more sleep disturbances compared to their healthy peers.

METHODS

This study, designed as a cross-sectional case-control investigation, involved a cohort of 250 participants (144 T1D, 106 control cases) aged 6-15 years. The Sleep Disturbance Scale for Children (SDCS) scores of the T1D group were compared with those of the control group. Furthermore, the study explored the correlation between clinical/biochemical parameters and SDCS scores within the T1D group.

RESULTS

The mean age of individuals in the T1D group was 10.27 ± 3.25 years, while the control group had a comparable mean age of 10.48 ± 3.5 years (P = 0.303). Within the T1D group, the median duration of diabetes was 5 (1-15) years, and the median glycosylated hemoglobin A1c (HbA1c) level for the past one year was 8.4 %. Although there was no significant difference in total SDSC scores between the T1D and control groups, both groups exhibited average scores that remained close to the threshold indicative of sleep disturbances (>39). Notably, individuals with total SDSC scores surpassing 39 were identified at rates of 48.6 % in the T1D group and 47.6 % in the control group, respectively. Furthermore, disorders of arousal nightmares (DA) were more prevalent in T1D patients compared to their healthy peers (P = 0.049). Additionally, HbA1c showed a positive correlation with scores for disorders of excessive somnolence (DOES) and total scores (P < 0.001, R = 0.368; P = 0.003, R = 0.243).

CONCLUSION

Our study found that the prevalence of sleep disturbances among children and adolescents with T1D was not significantly higher than that observed in their healthy peers. Nevertheless, it is crucial to note that a notable portion, 48.6 % of T1D cases and 47.6 % of healthy cases, displayed sleep disturbances based on SDSC scores. To optimize diabetes management and proactively address potential challenges, incorporating routine screening for sleep disturbances in the monitoring of T1D patients can yield valuable benefits.

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.

Childhood sleep: assessments, risk factors, and potential mechanisms

BACKGROUND

Sleep problem is a highly prevalent health issue among pediatric populations across the world. In this review, we aimed to identify risk factors contributing to sleep deficiency and poor sleep hygiene in children. Potential biological, psychosocial, and environmental mechanisms as well as research gaps in the literature are also discussed.

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. Both relevant data based and systematic reviews are included.

RESULTS

This paper summarizes many risk factors for childhood sleep problems, including biological (e.g., genetics, gender, age and puberty, prenatal factors, postnatal factors); nutritional (e.g., macronutrients, micronutrients, omega-3 fatty acids, obesity); environmental (e.g., heavy metals, noise, light, air pollution); interpersonal (e.g., family, exposure to violence, screen media use, physical injury); and community/socioeconomic variables (e.g., racial/ethnicity and cultural factors, neighborhood conditions and socioeconomic status, school factors, public health disasters/emergencies), to better understand the development of sleep problems in children.

CONCLUSIONS

Poor childhood sleep is a multifactorial issue affected by a wide range of prenatal and early-life biological, environmental, and psychosocial risk factors and contributors. A better understanding of these risk factors and their mechanisms is an important first step to develop future research and prevention programs focusing on pediatric sleep problems.

Common Childhood Sleep Problems and Disorders

BACKGROUND

Sleep insufficiency and disturbances affect the physical, cognitive, and emotional well-being of children.

OBJECTIVE

To perform a narrative review on common sleep problems and disorders encountered in primary care for children and adolescents.

METHODS

A search of English literature in the Pubmed and Google Scholar databases published from 1 January 2000 till 31 October 2021 was conducted with the keywords "sleep problem" or "sleep disorder" and "child" or "adolescent". Findings in the relevant articles and cross-references were compiled.

RESULTS

Sleep duration and habits of children vary widely across countries with different cultural backgrounds. There is robust evidence to support the promotion of positive bedtime routines and sleep hygiene as prevention and management of sleep problems. 15-70% of parents reported their children having sleep problems or disturbances. Common sleep complaints include difficulty in initiation or maintenance of sleep, abnormal behaviors or movements, snoring or abnormal breathing, and excessive daytime sleepiness. Comprehensive sleep history and a sleep diary are the first steps for evaluation. Home video and actigraphy may be used as preliminary tools to confirm the history. Referrals to a sleep specialist for polysomnography and other tests are needed, if suspecting specific sleep disorders, such as obstructive sleep apnea and narcolepsy, needs timely intervention. Common sleep disorders in different age groups encountered in primary care are reviewed with clinical features, indications for evaluation, and treatment options summarized.

CONCLUSION

Screening for sleep problems shall be an integral part of each child's health care visit. It is important to evaluate the impact of common sleep problems and identify specific sleep disorders for early intervention to prevent long-term adverse outcomes.

Validation of the newly developed Sleep Screening Questionnaire Children and Adolescents (SSQ-CA) with objective sleep measures

OBJECTIVES

Objectively validated pediatric sleep questionnaires covering a broader age range and different sleep disturbances are lacking, therefore we developed the Sleep Screening Questionnaire Children and Adolescents (SSQ-CA) and compared it with objective sleep parameters.

METHODS

This child-reported questionnaire was developed by a multidisciplinary panel and face validated. In a cross-sectional prospective design, participants aged 6-17, answered the questionnaire twice with 21-28 days in between, wore actigraphy (AG) and kept a sleep diary for seven nights and home-polysomnography (PSG) for one of these nights. Exploratory factor analyses (EFA), reliability and validity assessments were performed.

RESULTS

Of the 139 participants, 128 (F:47.7%, AG: n = 128, PSG: n = 59), were included in the analyses. Mean age: 11.3 years (SD: 2.9). EFA revealed 11 factors and 40 items loading above r = 0.4. Subscale internal consistency: 0.54-0.92. Subscale test-retest reliability: r = 0.71-0.87. Total sleep time (TST) from SSQ-CA on weekdays correlated with PSG (r = 0.48, p = 0.001) and with AG (r = 0.75, p < 0.001). The subscale total score for "Sleep duration and latency" correlated with TST from AG (r = -0.19, p = 0.03) and sleep latency (r = 0.31, p < 0.001), but not for PSG variables. The subscale "Awakenings" showed no correlation with objective measures whereas "Circadian rhythm" correlated to AG-derived mid-sleep time (r = 0.34, p < 0.001).

CONCLUSIONS

The SSQ-CA shows adequate reliability for the 6-17-year-olds and acceptable criterion validity for two subscales. It appears to be a useful tool for screening for sleep disturbances in combination with objective tools as the subjective and objective parameters seem to uncover different aspects of sleep.

Sleep Disorders and Chronic Pain Syndromes in the Pediatric Population

Sleep problems are widespread in children and adolescents suffering from chronic pain disorders. Sleep loss intensifies the experience of pain and is detrimental to the budding self-efficacy of a young individual with limitless horizons. Addressing sleep disorders may prevent the chronification of pain and prevent adverse health outcomes, such as functional impairment, psychiatric comorbidities and overall poor quality of life. This review will explore the cyclical nature between sleep, pain and mood, as well as the functional impact of this relationship on children and adolescents. There will be a discussion about sleep assessment and diagnostic testing, followed by a description of sleep disturbances found in specific pain conditions, ranging from headache, musculoskeletal/abdominal pain, to rheumatologic disorders. Finally, there will be a brief review of pharmacologic and behavioral interventions designed to improve sleep quality, and when possible, to alleviate pain.

July 14th 2016 Nice Terrorist Attack Court Trial: A Protocol on Sleep Quality and Somatic Symptoms as Markers of Risk for Traumatic Reactivation in Adolescents Exposed to This Attack

The court trial of the 14th of July 2016 terrorist attack in Nice (France) opened in September 2022 and ended in December 2022. Engaging in court proceedings, whether as a victim or a witness, can lead to a significant risk of traumatic reactivation (i.e., the re-emergence of post-traumatic stress symptoms). The present protocol aimed to improve knowledge of the pathophysiology of traumatic reactivation due to the media coverage of the trial by assessing sleep disturbances and somatic symptoms that could reappear if there is a traumatic reactivation. Method and Analysis: This is a monocentric longitudinal study, with recruitment solely planned at the Nice Pediatric Psychotrauma Center (NPPC). We intended to include 100 adolescents aged 12 to 17 years who were directly or indirectly exposed to the attack and included in the "14-7" program). Assessments began one month before the trial, in August 2022, and were scheduled once a month until the end of the trial. A smartwatch recorded sleep activity. Somatic and PTSD symptoms and sleep were assessed through validated questionnaires. The main analyses comprised the variance and regression analyses of predictors of clinical evolution over time. Ethics and Dissemination: The National Ethics Committee "NORD OUEST III" approved the "14-7" program protocol (number 2017-A02212-51). The specific amendment for this research was approved in April 2022 by the same national ethical committee. Inclusions started in August 2022.

Understanding the Impact of Insufficient Sleep in Children with Behavior Problems on Caregiver Stress: Results from a U.S. National Study

Research indicates strong connections between child ADHD, child ODD/CD, and sleep. Children experiencing these concerns also have caregivers who report feeling more stress. However, no studies have examined how child ADHD and ODD/CD interact together and with insufficient sleep to potentially exacerbate caregiver stress. Data were acquired from the 2018/2019 National Survey of Children's Health, a nationally representative survey of parents or caregivers conducted across the United States (U.S.). The current study used data for children 6-17 years old with a final analytic sample size of 41,541, representing a total of 47,357,862 U.S. youth. Overall child ADHD and ODD/CD were each uniquely associated with increased caregiver stress, while adequate child sleep duration was related to decreased caregiver stress. However, these findings were qualified by a significant two-way interaction that revealed that caregiver stress among children with comorbid ADHD and ODD/CD was not significantly greater than that of children with ODD/CD alone. Significant interactions between sleep and ODD/CD on caregiver stress were generally not observed, except potentially in females with ADHD. Our findings underscore the importance of considering strategies to reduce both youth symptoms and caregiver stress simultaneously. Additionally, ensuring adequate sleep for all children is recommended.

Discrepancies Between Caregiver Reported Early Childhood Sleep Problems and Clinician Documentation and Referral

OBJECTIVE

The American Academy of Pediatrics recommends routine sleep problem screenings during child well-visits. However, studies suggest a discrepancy between caregiver- and clinician-reported child sleep problems. The present study examines whether caregiver-reported child sleep problems (ie, habitual snoring, insomnia symptoms, poor sleep health) and clinician-documented child sleep problems and management are congruent.

METHODS

The sample included 170 caregiver-child dyads (child Mage = 3.3 years, range = 2-5 years; 56.5% girls; 64.1% Black, 20.0% non-Latinx White, and 4.1% Latinx; 86.5% maternal caregiver reporter). Caregivers' questionnaire-based reports of habitual snoring, insomnia symptoms, and sleep health behaviors (nighttime electronics, caffeine intake, insufficient sleep) were compared with clinician documentation in the electronic health record.

RESULTS

About 92.3% of children had at least 1 caregiver-reported sleep problem (66% insomnia symptoms, 64% electronics, 38% insufficient sleep, 21% caffeine, 17% snoring). In contrast, a substantially lower percent of children had a clinician documented sleep problem (20% overall; 10% insomnia symptoms, 7% electronics, 0% insufficient sleep, 3% caffeine, 4% snoring), sleep-related referral (1% overall; 0.6% Otolaryngology, 0.6% polysomnogram, 0% sleep clinic), or recommendation (12% overall; 8% insomnia symptoms, 4% electronics, 0% insufficient sleep, 1% caffeine).

CONCLUSIONS

There is a vast discrepancy between caregiver-reported child sleep problems and clinician-documented sleep problems and management, with a higher proportion of caregiver reports. To benefit overall child health and well-being, future research and quality improvement initiatives should focus on enhancing screening tools and educational opportunities to improve clinician documentation and enhance family conversations about early childhood sleep problems.

Sleep Disorders in Childhood

OBJECTIVE

This article provides a comprehensive review of pediatric sleep disorders including the clinical features, diagnosis, and treatment of sleep-disordered breathing, insomnia, parasomnias, restless sleep disorder, restless legs syndrome, narcolepsy in childhood, and Kleine-Levin syndrome.

LATEST DEVELOPMENTS

Our understanding of pediatric sleep pathophysiology continues to evolve, and diagnostic and treatment modalities have expanded. A low-sodium oxybate formulation was approved in July 2020 in the United States to treat cataplexy and excessive daytime sleepiness in patients 7 years old and older with narcolepsy. A validated pediatric hypersomnolence survey for pediatric narcolepsy and idiopathic hypersomnia with high sensitivity, specificity, and interrater reliability is now available.

ESSENTIAL POINTS

The clinical presentation, diagnostics, and treatment of children with sleep disorders differ from those of adults. Untreated sleep disorders in childhood can lead to adverse physical and psychological consequences in adults. Correctly diagnosing and treating sleep disorders in youth can prevent a significant burden of disease in adulthood.

Health Disparities in Pediatric Sleep

This article reviews disparities in pediatric sleep health and sleep disorders from early childhood through adolescence (birth to age 18 years). Sleep health is a multidimensional construct including sleep duration, consolidation, and other domains, whereas sleep disorders reflect both behaviorally (eg, insomnia) and medically based (eg, sleep disordered breathing) sleep diagnoses. Using a socioecological framework, we review multilevel (ie, child, family, school, health-care system, neighborhood, and sociocultural) factors linked to sleep health disparities. Mechanistic research and studies using an intersectional lens to understand overlapping marginalized identities are needed to inform multilevel interventions to promote sleep health equity in pediatrics.

Sleep Micro-Macro-structures in Psychophysiological Insomnia. PSG Study

Study Objectives

To address sleep micro-macro-structures in psychophysiological insomnia (PPI) as denoted by cyclic alternating pattern (CAP), Sleep spindles, and hyperarousal as microstructures and sleep characteristics such as sleep stages' variables, and heart rate as macrostructures.

Methods

Two statistical populations, with 20 participants in each, are addressed: good sleepers (GS) and patients with psychophysiological insomnia (PPI). The sleep polysomnography (PSG) for one night was performed and sleep macro-micro-structures extraction was implemented for each participant. Cyclic alternating patterns were scored manually and other structures were monitored by the original PSG's device software. Analytical methods are used to dissect the results.

Result

The findings imply: (a) psychophysiological insomnia is characterized by CAP differences from good sleepers which are associated with hyperarousal; (b) Regarding microstructure, more microarousals in sleep stages caused more number of wake index. (c) The ratio of sleep stages, sleep latency and heart rate as sleep macrostructure are significantly changed. (d) There is no significant difference between PPI and GS groups on spindles length in our research.

Conclusion

Regarding all sleep disorders and especially PPI, CAP variables, EEG arousals, and sleep spindles as microstructures and Total Sleep Time, Sleep Latency, number of waking, REM duration, and Heart Rate as macrostructures were found to be critical for the diagnosis of psychophysiological insomnia The analysis contributes to understanding better approaches in the quantitative specification of psychophysiological insomnia compare to good sleepers.

Prevalence of sleep problems and habits among children in Saudi Arabia: A cross-sectional study

OBJECTIVES

To investigate children's sleep problems, habits, and lifestyle changes.

METHODS

A cross-sectional study was carried out in Riyadh, Saudi Arabia, over a period of 2 months, from August through September 2022, with parents of children aged 2-14 years after reviewing the literature and formulating a validated Google questionnaire containing 30 questions related to sleep habits, problems, and disorders.

RESULTS

In total, 585 questionnaires were included in the analysis. The sample comprised 345 (59%) males and 240 (41%) females. The mean age of patients was 7 (range: 2-14) years. Bed-time resistance was the most prevalent sleep problem (70.3%), followed by sleep-onset delay (58.1%), difficulty waking up in the morning on weekdays (41.3%), weekends (38%), and interrupted sleep (31%). An alarmingly high prevalence of hyperactivity (41.8%) and aggressive behaviour (42.2%) was noted. Co-sleeping with parents was reported in 41% of children. Night terror was reported in 20.6% and 26.5% in nightmares. Statistically significant associations were noted between screen time, snoring, and witnessed apnoea with sleep problems.

CONCLUSION

Sleep problems are common among children in Saudi Arabia. The study sheds some light on sleep habits and practices in this age group in Saudi Arabia, such as the high prevalence of bed-time resistance and sleep-onset delay, hyperactivity, and sleep-affecting culprits such as screen time, snoring, and witnessed apnoea.

Socioeconomic status and sleep health: a narrative synthesis of 3 decades of empirical research

STUDY OBJECTIVES

This review aims to assess the association between socioeconomic status (SES) and sleep health in the general population and the mediating effects of lifestyle and mental and physical health in this relationship.

METHODS

Observational studies testing the independent association between objective or subjective SES indicators and behavioral/physiological or clinical sleep health variables in the general population were included. PubMed/MEDLINE was searched for reports published from January 1990 to December 2019. The direction of effect was used as the primary effect measure, testing the hypothesis that low SES is associated with poor sleep health outcomes. Results are presented in the form of direction effect plots and synthesized as binomial proportions.

RESULTS

Overall, 336 studies were identified. A high proportion of effects at the expected direction was noted for measures of sleep continuity (100% for sleep latency, 50-100% for awakenings, 66.7-100% for sleep efficiency), symptoms of disturbed sleep (75-94.1% for insomnia, 66.7-100% for sleep-disordered breathing, 60-100% for hypersomnia), and general sleep satisfaction (62.5-100%), while the effect on sleep duration was inconsistent and depended on the specific SES variable (92.3% for subjective SES, 31.7% for employment status). Lifestyle habits, chronic illnesses, and psychological factors were identified as key mediators of the SES-sleep relationship.

CONCLUSIONS

Unhealthy behaviors, increased stress levels, and limited access to health care in low-SES individuals may explain the SES-sleep health gradient. However, the cross-sectional design of most studies and the high heterogeneity in employed measures of SES and sleep limit the quality of evidence. Further research is warranted due to important implications for health issues and policy changes.

Longitudinal associations between parent, child, family factors and dyssomnias in children from birth to 8 years: The CIKEO study

BACKGROUND

Dyssomnias, are the most common parent-reported sleep complaints in young children. The present study investigated the prevalence, one-year development (incidence and persistence) of dyssomnia in early childhood, and the parent, child, and family factors associated with dyssomnia.

METHODS

Longitudinal data of 700 children aged 0-8, gathered in the CIKEO cohort study in the Netherlands were analyzed. Dyssomnias were defined as the presence of night awakenings ≥3 times per night or sleep-onset latency of >30 min. Least absolute shrinkage and selection operator (LASSO) was used to identify the parental, child, and family factors associated with the incidence and persistence of dyssomnias in children.

RESULTS

The mean age of the children (47 % girls) was 3.2 ± 1.9 years at baseline and 4.4 ± 1.8 years at follow-up. The prevalence of dyssomnias was 13.3 % and 15.4 % at baseline and follow-up, respectively. The incidence and persistence rates of dyssomnias at follow-up were 12.0 % and 37.6 %, respectively. New incidence of insomnia was associated with being a girl, having medical conditions, experiencing stressful life events, and lower parenting self-efficacy at baseline (P < 0.05). Higher levels of parental psychological distress were associated with the persistence of dyssomnias in children (P < 0.05).

CONCLUSIONS

Dyssomnias are common with a moderate persistent rate in young children. Several parental, child, and family factors in relation to the incidence and persistence of dyssomnias were identified. Preventive programs and interventions targeting modifiable factors, particularly parental psychological distress, parenting self-efficacy, and resilience to stressful life events, might benefit child sleep.

Insomnia in Infancy, Childhood, and Adolescence

Insomnia is the most prevalent sleep disorder in youth, tends to persist over time, and is associated with a myriad of adverse outcomes. This paper synthesizes the current evidence regarding the phenomenology, prevalence, assessment, consequences, cause, and treatment of pediatric insomnia, highlighting areas that warrant further research and addressing the unique characteristics of this disorder in infants, children, and adolescents.

Understanding the research on tracking, diagnosing, and intervening in sleep disorders using mHealth apps: Bibliometric analysis and systematic reviews

Objectives

In solving the global challenge of sleep disorders, Mobile Health app is one of the important means to monitor, diagnose, and intervene in sleep disorders. This study aims to (1) summarize the status and trends of research in this field; (2) assess the production and usage of sleep mHealth apps; (3) calculate the conversion rate of grants that the proportion of newly developed apps from being funded and developed to published on application stores.

Methods

Using bibliometric and content analysis methods, based on "Research Paper-Product Output-Product Application" chain and considering the "Research Grants" of articles, we conducted a systematic review of eight databases, to identify relevant studies over the last decade.

Results

Over the past decade, 1399 authors published 313 papers in 182 journals and conferences. The number of publications increased with an average annual growth of 41.6%. The current focus area is research using cognitive behavioral therapy to intervene in sleep. Sleep-staging tracking is a shortcoming of this field. A total 368 sleep mHealth apps (233 newly developed and 135 existing) were examined in 313 papers; 323 grants supported 178 articles (56.9%). Only 12 of the newly developed apps are used in the real world, resulting in a 9% grant conversion rate.

Conclusions

In the last decade, the field of tracking, diagnosing, and intervening in sleep disorders using mHealth apps has shown a trend of rapid development. However, the conversion rate of products from being funded and developed for use by end-users is low.

Association between sleep habits and behavioral problems in early adolescence: a descriptive study

Background

Sleep habits are related to children's behavior, emotions, and cognitive functioning. A strong relationship exists between sleep habits and behavioral problems. However, precisely which sleep habits are associated with behavioral problems remains unclear. Therefore, the purpose of this study is to clarify the relationship between sleep habits and behavioral problems in early adolescence.

Methods

This study used data from a larger longitudinal research, specifically, data from the year 2021. First-year junior high school students (12–14 years) in Japan were surveyed; their parents (N = 1288) completed a parent-report questionnaire. The main survey items were subject attributes, the Pittsburgh Sleep Quality Index (PSQI), and the Strength and Difficulties Questionnaire (SDQ).

Results

Of the 652 valid responses received, 604 individuals who met the eligibility criteria (no developmental disability in the child and completion of all survey items) were included in the analysis. To examine the relationship between sleep habits and behavioral problems, logistic regression analysis using the inverse weighted method with propensity score was conducted with sleep habits (sleep quality, time to fall asleep, sleep duration, sleep efficiency, sleep difficulty, use of sleeping pills, difficulty waking during the day, and sleep disturbances) as explanatory variables and behavioral problems (overall difficulty in SDQ) as objective variables. The propensity score was calculated by employing the logistic regression using the inverse weighted method based on propensity scores. Propensity scores were calculated based on gender, family structure, household income, and parental educational background. The results showed that behavioral problems tended to be significantly higher in the group at risk for sleep quality, sleep difficulties, daytime arousal difficulties, and sleep disturbances than in the group with no risk.

Conclusion

The results suggest that deterioration in sleep quality, sleep difficulties, daytime arousal difficulties, and sleep disturbances may increase the risk of behavioral problems in adolescents.

Prevalence and Treatment Patterns of Sleep Disorders in the Under 20 Population: analysis using a national health insurance claims database

Objectives

Child and adolescent sleep is an important factor for brain and physical development. Therefore, it is necessary to investigate the prevalence of sleep disorders and nonorganic sleep disorders in children and adolescents and determine the type of utilization of medical institutions. This study analyzed the prevalence and type of medical institutions in Korean children and adolescents with sleep disorders and nonorganic sleep disorders.

Methods

This study used data recorded in the Health Insurance Review and Assessment-National Patient Sample (HIRA-NPS) database from 2010 to 2017. Details of medical institution type and patient’s sex, age, and treatment type were extracted for patients younger than 20 years with sleep disorders and nonorganic sleep disorders.

Results

Among 2,536,478 patients under age 20, we identified 3,772 patients with sleep disorders or nonorganic sleep disorders. From 2010 to 2017, the prevalence of sleep disorders in children and adolescents was 0.07% to 0.09%. The utilization rate of Korean medical institutions was 30.47%. The prevalence of nonorganic sleep disorders and the utilization rate of Korean medical institutions were 0.06% to 0.08% and 45.99%, respectively.

Conclusion

The prevalence of sleep disorders and nonorganic sleep disorders in the under-20 population was 0.14% to 0.16%. More than 70% of patients with nonorganic sleep disorder who were younger than 9 years used Korean medical institutions.

Oral language skills in Brazilian children with obstructive sleep apnea

BACKGROUND

Obstructive sleep apnea (OSA) is associated with a negative impact on neurocognitive development in children. Receptive/expressive oral language is a complex process, with limited investigations on the repercussion of OSA. This study aimed to analyze receptive and expressive oral language skills in children with obstructive sleep apnea (OSA).

METHODOLOGY

This study included 52 children (27 females, 51.92 %) with a mean age of 7 ± 2 years (age range of 4-11 years), which underwent type 3 polysomnography (PSG). The participants were divided into N-OSA (n = 16) and OSA (n = 36) groups based on the apnea-hypopnea index. The speech-language therapist evaluated hearing and oral language for phonology, expressive semantics, syntax, receptive semantics (Peabody Image Vocabulary Test), pragmatics, and understanding of verbal instructions (Token Test).

RESULTS

Oral language assessments showed a difference in the pragmatics subsystem (p = 0.047), with positive correlation between OSA severity and oral language functions such as pragmatics and syntax (desaturation index, p = 0.045).

CONCLUSION

Obstructive sleep apnea (OSA) had a negative impact on oral language skills, including the syntax and pragmatics subsystems.

Characteristics associated with caregiver willingness to consider tonsillectomy for a child's obstructive sleep disordered breathing: Findings from a survey of families in an urban primary care network

OBJECTIVE

Tonsillectomy use is lower among Black children than White children in the U.S. despite their higher prevalence of obstructive sleep disordered breathing (oSDB). We aimed to identify factors associated with parents' willingness to consider tonsillectomy for their child's oSDB and to identify whether parents of Black children are less willing than parents of non-Black children to be willing to consider the procedure.

STUDY DESIGN

Prospective cohort study.

SETTING

Primary care network of a tertiary children's hospital.

METHODS

We surveyed parents/guardians of children aged 2-10 years with oSDB, to assess their knowledge about oSDB and tonsillectomy, perceived severity of their child's oSDB, perceived level of their child's sleep disturbance, perceived risks and benefits of tonsillectomy, stress, trust in their child's primary care physician and physicians in general, and health literacy. We also assessed child clinical and sociodemographic characteristics. Associations between these characteristics and parent/guardian willingness to consider tonsillectomy for their child's oSDB were assessed.

RESULTS

Of the 59 parents/guardians included, 90% were mothers and 71% were Black. Only 58% of caregivers of Black children but 85% of caregivers of non-Black children were willing to consider tonsillectomy (p = 0.04). Caregivers with another child who had undergone tonsillectomy and caregivers who perceived their child's sleep to be more disturbed were more often willing to consider tonsillectomy (both p = 0.02).

CONCLUSIONS

Parents of Black children are less willing to consider tonsillectomy for their child's oSDB, but this was not explained by any factors assessed in this study. Future studies should evaluate additional factors that may explain this difference and that might be targeted to ensure appropriate and equitable access to tonsillectomy among children with oSDB.

Rates of diagnoses of sleep disorders in children with chronic medical conditions

STUDY OBJECTIVES

This investigation examines sleep disorder (SD) diagnoses in a large population of children and adolescents with chronic medical conditions (CMCs). Little is known about SD diagnoses in this population. The large population used in this study allowed examination of SD rates by CMC type and demographics.

METHODS

Data were from the Coordinated Health Care for Complex Kids (CHECK) project designed for Medicaid-funded children and adolescents with at least one CMC from a large metropolitan area. The study population (N=16,609) was limited to children and adolescents, 0 to 18 years of age. SD and CMC diagnoses were obtained from Medicaid claims data.

RESULTS

Fourteen percent of the population (mean age of 9.1 years [SD= 5.2]; 35.8% African American (AA); 56.4% male; 77 with more than one CMC) received a sleep disorder diagnosis. The most frequent diagnosis was SDB (11.2%), followed by nocturnal enuresis (1.2%), and insomnia (1%). SDs were diagnosed more frequently in those with multiple CMCs than in those with one CMC (19.7% vs. 5.8%; p <0.001). Insomnia rates in Hispanic/Latinx (1.2%) and AA (0.8%) children and adolescents were significantly lower (both p<0.001) than in Caucasians (3.5%). Odds of receiving a sleep diagnosis varied among CMCs.

CONCLUSIONS

Our analysis of Medicaid claims data of a large urban cohort offers detailed information about the rates of sleep diagnoses and suggests under-diagnosis of SDs in this vulnerable, high-risk, primarily ethnic minority population. Under-recognition of sleep disorders have short- and long-term health and economic consequences. Study results may help clinicians implement appropriate SD screening and management for children and adolescents with CMCs.

Association Between Exposure to Outdoor Artificial Light at Night and Sleep Disorders Among Children in China

IMPORTANCE

Healthy sleep has an important role in the physical and mental health of children. However, few studies have investigated the association between outdoor artificial light at night (ALAN) and sleep disorders in children.

OBJECTIVE

To explore the associations between outdoor ALAN exposure and sleep disorders in children.

DESIGN, SETTING, AND PARTICIPANTS

This population-based cross-sectional study, part of the National Chinese Children Health Study, was conducted from April 1, 2012, to June 30, 2013, in the first stage and from May 1, 2016, to May 31, 2018, in the second stage in 55 districts of 14 cities in China. This analysis included 201 994 children and adolescents aged 2 to 18 years. Data were analyzed from February 20 to March 21, 2022.

EXPOSURES

Outdoor ALAN exposure (in nanowatts per centimeters squared per steradian) within 500 m of each participant's residential address obtained from the satellite imagery data, with a resolution of approximately 500 m.

MAIN OUTCOMES AND MEASURES

Sleep disorders were measured by the Chinese version of the Sleep Disturbance Scale for Children. Generalized linear mixed models were used to estimate the associations of outdoor ALAN with sleep scores and sleep disorders.

RESULTS

The study included 201 994 children and adolescents (mean [SD] age, 11.3 [3.2] years; 106 378 boys [52.7%]), 7166 (3.5%) of whom had sleep disorder symptoms. Outdoor ALAN exposure of study participants ranged from 0.02 to 113.48 nW/cm2/sr. Compared with the lowest quintile (Q1) of outdoor ALAN exposure, higher quintiles of exposure (Q2-Q5) were associated with an increase in total sleep scores of 0.81 (95% CI, 0.66-0.96) in Q2, 0.83 (95% CI, 0.68-0.97) in Q3, 0.62 (95% CI, 0.46-0.77) in Q4, and 0.53 (95% CI, 0.36-0.70) in Q5. Higher quintiles of exposure were also associated with odds ratios for sleep disorder of 1.34 (95% CI, 1.23-1.45) in Q2, 1.43 (95% CI, 1.32-1.55) in Q3, 1.31 (95% CI, 1.21-1.43) in Q4, and 1.25 (95% CI, 1.14-1.38) in Q5. Similar associations were observed for sleep disorder subtypes. In addition, greater effect estimates were found among children younger than 12 years.

CONCLUSIONS AND RELEVANCE

The findings of this cross-sectional study suggest that sleep disorders are more prevalent among children residing in areas with high levels of outdoor ALAN and the associations are generally stronger in children younger than 12 years. These findings further suggest that effective control of outdoor ALAN may be an important measure for improving the quality of children's sleep.

Evidence-Based Behavioral Strategies in Smartphone Apps for Children's Sleep: Content Analysis

BACKGROUND

Empirically supported treatments for pediatric sleep problems exist, but many families turn to other sources for help with their children's sleep, such as smartphone apps. Sleep apps are easy for families to access, but little evidence exists regarding the validity of the services and information provided in the developer descriptions of the apps.

OBJECTIVE

The goal of this study was to examine the features and claims of developer descriptions of sleep apps for children.

METHODS

A search of the Apple iTunes store and Google Play was conducted using the terms "kids sleep," "child sleep," and "baby sleep." Data on the type of app, price, user rating, and number of users were collected. Apps were analyzed in comparison with evidence-based behavioral strategies and were thematically coded on the basis of claims provided in developer descriptions.

RESULTS

A total of 83 app descriptions were examined, of which only 2 (2.4%) offered sleep improvement strategies. The majority were sound and light apps (78%) and 19% were bedtime games or stories. Only 18 of 83 (21.6%) apps were identified as containing empirically supported behavioral sleep strategies. Despite this, many apps asserted claims that they will help children "fall asleep instantly," "cry less and sleep better," or improve child development.

CONCLUSIONS

A large variety of sleep apps exist for use among children, but few include evidence-based behavioral strategies according to the developer descriptions of the apps. Addressing sleep difficulties in children is important to promote physical, cognitive, and emotional development. Collaboration between sleep researchers and technology developers may be beneficial for creating evidence-supported apps to help with children's sleep in the future.

Measuring Sleep Health Disparities with Polysomnography: A Systematic Review of Preliminary Findings

Socioeconomic status (SES) has an unrecognized influence on behavioral risk factors as well as public health strategies related to sleep health disparities. In addition to that, objectively measuring SES’ influence on sleep health is challenging. A systematic review of polysomnography (PSG) studies investigating the relation between SES and sleep health disparities is worthy of interest and holds potential for future studies and recommendations. A literature search in databases was conducted following Prisma guidelines. Search strategy identified seven studies fitting within the inclusion criteria. They were all cross-sectional studies with only adults. Except for one study conducted in India, all of these studies took place in western countries. Overall emerging trends are: (1) low SES with its indicators (income, education, occupation and employment) are negatively associated with PSG parameters and (2) environmental factors (outside noise, room temperature and health worries); sex/gender and BMI were the main moderators of the relation between socioeconomic indicators and the variation of sleep recording with PSG. Socioeconomic inequalities in sleep health can be measured objectively. It will be worthy to examine the SES of participants and patients before they undergo PSG investigation. PSG studies should always collect socioeconomic data to discover important connections between SES and PSG. It will be interesting to compare PSG data of people from different SES in longitudinal studies and analyze the intensity of variations through time.

Prevalence of Sleep Disorders, Risk Factors and Sleep Treatment Needs of Adolescents and Young Adult Childhood Cancer Patients in Follow-Up after Treatment

BACKGROUND

Sleep disorders negatively impact adolescent and young adult childhood cancer patients' physical and psychosocial health. Early recognition improves timely treatment. We therefore studied the prevalence of subjective sleep disorders, risk factors and sleep treatment needs after completion of childhood cancer treatment.

METHODS

Childhood cancer patients (12-26 years old), ≥6 months after treatment, were invited to fill out the Holland Sleep Disorders Questionnaire, which distinguishes six sleep disorders in substantial agreement with the International Classification of Sleep Disorders, second edition (ICSD-2). They additionally indicated sleep treatment needs. Prevalence rates and needs were displayed in percentages. Logistic regression models were used for risk factors.

RESULTS

576 patients participated (response rate 55.8%)-49.5% females, mean age 17.0 years, 44.4% hemato-oncology, 31.9% solid tumors, 23.6% neuro-oncology. Prevalence rates were: insomnia (9.6%), circadian rhythm sleep disorder (CRSD; 8.1%), restless legs syndrome (7.6%), parasomnia (3.5%), hypersomnia (3.5%) and sleep-related breathing disorders (1.8%). Female sex, comorbid health conditions and young adulthood seem to be risk factors for sleep disorders, but cancer-related factors were not. Differing per sleep disorder, 42-72% wanted help, but only 0-5.6% received sleep treatment.

CONCLUSIONS

Insomnia and CRSD were most prevalent. An unmet need for sleep treatment was reported by childhood cancer patients during follow-up. Screening for sleep disorders after cancer might improve access to treatment and patient wellbeing.

Correlates of a caregiver-reported child sleep problem and variation by community disadvantage

BACKGROUND

Previous studies of sleep patterns and perceived problems in early childhood indicate variation by family socioeconomic status. The purpose of this study was to examine variation in correlates of a caregiver-perceived child sleep problem across and within levels of community disadvantage in a large US sample.

METHODS

Caregivers of 14,980 young children (ages 0-35.9 months) in the US completed the Brief Infant Sleep Questionnaire-Revised (BISQ-R) on the freely and publicly available Johnson's® Bedtime® Baby Sleep App. Zip code was used to identify a Distressed Communities Index (DCI) score, which represents community disadvantage based on neighborhood indicators.

RESULTS

Across all levels of community disadvantage, caregivers who reported greater impact of child sleep on their own sleep, bedtime difficulty, more frequent and longer night wakings, and increased total nighttime sleep were more likely to endorse a child sleep problem. These associations varied by level of community disadvantage. For caregivers living in more disadvantaged communities, impact of child sleep on their own sleep and night wakings were the strongest correlates of endorsing a child sleep problem, whereas for those in more advantaged communities the impact of child sleep on their own sleep and night wakings as well as additional aspects of sleep health, such as short sleep duration, were associated with endorsement of a child sleep problem.

CONCLUSIONS

Findings suggest that families living in more distressed communities are most likely to identify the impact of child sleep on their own sleep and night wakings in reporting a child sleep problem, whereas those from more prosperous communities consider these factors as well as other sleep parameters, including sleep duration. Clinicians should consider expanding screening questions for child sleep problems to include the perceived impact on caregiver sleep.

Pediatric Obstructive Sleep Apnea: What’s in a Name?

Obstructive sleep apnea is a highly prevalent disease across the lifespan and imposes substantial morbidities, some of which may become irreversible if the condition is not diagnosed and treated in a timely fashion. Here, we focus on the clinical and epidemiological characteristics of pediatric obstructive sleep apnea, describe some of the elements that by virtue of their presence facilitate the emergence of disrupted sleep and breathing and its downstream consequences, and also discuss the potential approaches to diagnosis in at-risk children.

Development of a classifier to screen for severe sleep disorders in children

This study aimed to develop an automatic classifier for the identification of severe sleep disorders that require immediate intervention in children. Our study assessed 7,008 children (age: 0-83 months) in Japan, whose parents and nursery teachers recorded their 14-day sleep patterns. Sleep quality was assessed by pediatricians and scored as 1 (no severe sleep disorder) or 0 (severe sleep disorder). Discriminant analysis was performed for each age group using sleep quality (0 or 1) as the dependent variable and variables in the 14-day sleep log as independent variables. A stepwise method was used to select the independent variables to build the best model. The accuracy of the discriminant analysis for the age groups ranged from 71.3 to 97.3%. In summary, we developed an automatic classifier with sufficient application value to screen for severe sleep disorders in children. In the future, this classifier can be used to rapidly determine the presence or absence of severe sleep disorders in children based on their 14-day sleep logs, thus allowing immediate intervention.

Association Between Poor Sleep Quality and Glycemic Control in Adult Patients with Diabetes Referred to Endocrinology Clinic of Guilan: A Cross-sectional Study

BACKGROUND

Diabetes is a prevalent chronic medical comorbid condition worldwide. Diabetes mellitus is associated with various sleep disorders.

OBJECTIVES

We aimed to determine the prevalence of poor sleep and the main factors of sleep interruptions in patients with diabetes mellitus. We further evaluated the association of sleep interruptions with glycemic control in this cohort.

METHODS

We conducted a cross-sectional study on 266 patients with type 1 and type 2 diabetes recruited from a university outpatient endocrinology clinic. Patients completed a checklist including demographic and disease-related characteristics in addition to the Pittsburgh Sleep Quality Index (PSQI) to evaluate sleep quality. Using the PSQI cutoff score of 5, we created two subgroups of good sleepers (GS) and poor sleepers (PS).

RESULTS

Our results showed that good sleeper and poor sleeper patients with diabetes were significantly different regarding sex, employment status, BMI, presence of diabetes-related complications, HbA1c, and 2-hour postprandial blood sugar (2HPPBS) (all significant at P < 0.05). The most prevalent factors of sleep interruptions were "waking up to use a bathroom", "feeling hot", "pain", "having coughs or snores", and "bad dreams". Among the subjective factors of sleep interruption, problems with sleep initiation, maintenance, or early morning awakenings in addition to having pain or respiratory problems such as coughing or snoring had the most significant associations with HbA1c.

CONCLUSIONS

Our study showed significant subjective sleep disturbances (both quality and quantity) in patients with diabetes mellitus (both type I and II) and its association with diabetes control. We further identified the main factors that led to sleep interruptions in this cohort.

Sociodemographic Differences in Care Plans and Time to Treatment Among Children Being Considered for Adenotonsillectomy

OBJECTIVE

To assess sociodemographic differences in care plans and time to evaluation or treatment after otolaryngologic consultation among children with obstructive sleep-disordered breathing (oSDB).

STUDY DESIGN

Retrospective cohort study.

SETTING

Single tertiary children's hospital.

METHODS

We included children aged 2 to 9 years with oSDB seen from June to December 2018 as new otolaryngology clinic patients. Logistic regression was used to examine whether sociodemographic factors were associated with having adenotonsillectomy or polysomnography planned at the end of the visit. Kaplan-Meier analyses and Cox proportional hazards models were used to compare times to these events.

RESULTS

An overall 1020 children were included, of whom 65% were White and 18% were Black. Approximately 77% were metropolitan residents, 52% were publicly insured, and 88% of caregivers spoke primarily English. Treatment plans included adenotonsillectomy for 62% of patients, polysomnography for 15%, and new medication therapy for 13%. In multivariable analyses, there were no significant differences by child race/ethnicity, metropolitan/nonmetropolitan residence, type of health insurance, or caregiver primary language in the likelihood of having adenotonsillectomy or polysomnography planned. Among children for whom adenotonsillectomy was planned, children from metropolitan areas had greater times to surgery than children from nonmetropolitan areas (hazard ratio, 0.81 [95% CI, 0.66-0.99]; P = .04). This was explained by a difference between Black children from metropolitan areas and White children from nonmetropolitan areas (hazard ratio, 0.65 [95% CI, 0.49-0.86]; P = .003); there were no racial/ethnic differences in time to surgery among metropolitan-residing children (P = .09).

CONCLUSIONS

After initial otolaryngology consultation, children with oSDB from metropolitan areas have longer times to adenotonsillectomy than those from nonmetropolitan areas.

Headache and Sleep Disturbances in the Pediatric Population

The relationship between sleep disturbances and headaches in the pediatric population is bidirectional. Common underlying molecular mechanisms of sleep and headaches have been speculated to explain the clinical connection. We will summarize various sleep disturbances and their known relationships to headache, focusing on the pediatric population. Careful recognition and assessment of sleep disturbances in patients with headache is critical and may help guide treatment. First line therapies for sleep disturbances consist of behavioral approaches, though surgical and pharmacologic strategies are utilized in particular circumstances.

Association Between Sleep Disturbances With Neurodevelopmental Problems and Decreased Health-Related Quality of Life in Children With Fontan Circulation

Background Children with Fontan circulation are known to be at increased risk for neurodevelopmental problems and decreased health-related quality of life (HRQOL), but many factors that may contribute to this risk are unknown. Sleep disturbances may be one previously unidentified factor that contributes to this risk. Methods and Results We analyzed data from the Pediatric Heart Network Fontan cross-sectional study to evaluate associations between a parent or child report of sleep disturbance with reported neurodevelopmental concerns and HRQOL in 558 children with Fontan circulation. Parent-reported sleep disturbance was present in 11% of participants and child-reported sleep disturbance was present in 15%. Parent-reported sleep disturbance was associated with a significantly higher risk of attention problems, anxiety, depression, behavioral problems, and developmental delay (P<0.001 for all). Similarly, parent-reported disturbance was associated with decreased HRQOL on both parent and child-reported HRQOL (P<0.001 for most domains). Child-reported sleep disturbances were associated with increased odds of anxiety, depression, and attention problems as well as worse HRQOL. These associations were present even after adjustment for cardiac, demographic, and socioeconomic factors that may affect HRQOL and neurodevelopmental status. Conclusions Sleep disturbances in children with Fontan circulation are associated with an increased risk of neurodevelopmental problems as well as reduced HRQOL compared with those without sleep disturbance. Better understanding of sleep disturbances is needed in children with Fontan circulation, as sleep disturbances may represent a reversible cause of neurodevelopmental problems and decreased HRQOL in this population.

Practice Tools for Screening and Monitoring Insomnia in Children and Adolescents with Autism Spectrum Disorder

Between 50-80% of children with autism spectrum disorder (ASD) have insomnia, which adversely affects their mental and physical health. However, there is no consensus to-date on suitable tools for insomnia screening and monitoring in daily clinical practice. An expert panel of child neuropsychiatry and sleep specialists, with expertise in children with neurodevelopmental disabilities, recommends: (1) performing insomnia screening of all children with ASD; (2) considering discussion or referral to a sleep specialist when comorbid sleep disorders are suspected. The panel further developed structured, brief screening and monitoring tools to facilitate insomnia screening and management in daily practice, monitor treatment effectiveness and standardize and compare outcomes across clinical settings to improve care and well-being of children with ASD and their families.

Screening for Problematic Sleep in a Diverse Sample of Infants

OBJECTIVE

To examine screening strategies for identifying problematic sleep in a diverse sample of infants.

METHODS

Parents of infants (5-19 months; N = 3,271) presenting for a primary care visit responded to five screening items and the Infant Sleep Questionnaire (ISQ), a validated measure of problematic infant sleep. If parents responded affirmatively to any screening item, primary care providers received a prompt to evaluate. For each of the screening questions, we examined differences in item endorsement and criterion related validity with the ISQ. Using conceptual composites of night waking and sleep difficulty, prevalence, criterion-related validity, and concurrent demographic correlates were analyzed.

RESULTS

Infants were primarily of Black race (50.1%) or Hispanic ethnicity (31.7%), with the majority (63.3%) living in economically distressed communities. Rates of problematic sleep ranged from 7.4%, for a single item assessing parental perception of an infant having a sleep problem, to 74.0%, for a single item assessing night wakings requiring adult intervention. Items assessing sleep difficulty had high (95.0-97.8%) agreement with the ISQ in identifying infants without problematic sleep, but low agreement (24.9-34.0%) in identifying those with problematic sleep. The opposite was true for items assessing night waking, which identified 91.0-94.6% of those with sleep problems but only 31.8-46.9% of those without.

CONCLUSIONS

Screening strategies for identifying problematic infant sleep yielded highly variable prevalence rates and associated factors, depending on whether the strategy emphasized parent-perceived sleep difficulty or night wakings. The strategy that is most appropriate will depend on the system's goals.

Physical activity and sleep: An updated umbrella review of the 2018 Physical Activity Guidelines Advisory Committee report

Physical activity (PA) is widely considered to improve sleep, but a comprehensive review of the research on this topic has not been performed. In this umbrella review, conducted initially for the 2018 Physical Activity Guidelines for Americans Advisory Committee and updated to reflect more recent research, we examined whether PA enhances sleep outcomes across the lifespan as well as among individuals with sleep disorders. Systematic reviews and meta-analyses were utilized to assess the evidence. We also examined dose-response considerations and whether the association between PA and sleep was moderated by various factors (e.g., timing, sociodemographic characteristics). We found strong evidence that both acute bouts of PA and regular PA improved sleep outcomes. Moderate evidence indicated that longer bouts of PA (both acute and regular) improved sleep, and that the effects of PA on sleep outcomes were generally preserved across adult age groups and sex. Finally, moderate evidence demonstrated that PA improved sleep in adults with insomnia symptoms or obstructive sleep apnea. Several important areas in need of future research were also identified. Overall, the review supported the claim that PA improves sleep, but highlighted gaps that need to be addressed to facilitate more widespread utilization of PA for improving sleep.
