ABCs of SLEEPING: A review of the evidence behind pediatric sleep practice recommendations

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.

Black and Latiné parents' perspectives on supporting their children's emotional and physical health

Informed by integrative models of cultural resilience, the purpose of this study was to (a) explore how parents are promoting their children's emotional and physical health, with a focus on race and ethnic-racial socialization strategies, and (b) identify the barriers and challenges parents are experiencing in supporting their children's health. Ethnically racially matched qualitative interviews were conducted with 33 parents (82% women, 64% Black, 36% Latiné). Results of thematic analysis revealed three overarching themes: (a) Strategies for Promoting Children's Physical and Emotional Health, (b) Challenges Promoting Children's Physical and Emotional Health, and (c) Impact of Racism on Parenting and Children's Health. Most parents believed that racism had an impact on their parenting decisions and their children's health; however, there were some differences in ethnic-racial socialization practices between Black and Latiné parents. Findings have implications for culturally relevant parenting approaches to support children's emotional and physical health.

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.

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.

Are some children genetically predisposed to poor sleep? A polygenic risk study in the general population

BACKGROUND

Twin studies show moderate heritability of sleep traits: 40% for insomnia symptoms and 46% for sleep duration. Genome-wide association studies (GWAS) have identified genetic variants involved in insomnia and sleep duration in adults, but it is unknown whether these variants affect sleep during early development. We assessed whether polygenic risk scores for insomnia (PRS-I) and sleep duration (PRS-SD) affect sleep throughout early childhood to adolescence.

METHODS

We included 2,458 children of European ancestry (51% girls). Insomnia-related items of the Child Behavior Checklist were reported by mothers at child's age 1.5, 3, and 6 years. At 10-15 years, the Sleep Disturbance Scale for Children and actigraphy were assessed in a subsample (N = 975). Standardized PRS-I and PRS-SD (higher scores indicate genetic susceptibility for insomnia and longer sleep duration, respectively) were computed at multiple p-value thresholds based on largest GWAS to date.

RESULTS

Children with higher PRS-I had more insomnia-related sleep problems between 1.5 and 15 years (BPRS-I < 0.001 = .09, 95% CI: 0.05; 0.14). PRS-SD was not associated with mother-reported sleep problems. A higher PRS-SD was in turn associated with longer actigraphically estimated sleep duration (BPRS-SD < 5e08 = .05, 95% CI: 0.001; 0.09) and more wake after sleep onset (BPRS-SD < 0.005 = .25, 95% CI: 0.04; 0.47) at 10-15 years, but these associations did not survive multiple testing correction.

CONCLUSIONS

Children who are genetically predisposed to insomnia have more insomnia-like sleep problems, whereas those who are genetically predisposed to longer sleep have longer sleep duration, but are also more awake during the night in adolescence. This indicates that polygenic risk for sleep traits, based on GWAS in adults, affects sleep already in children.

From co-regulation to self-regulation: Maternal soothing strategies and self-efficacy in relation to maternal reports of infant regulation at 3 and 7 months

This study, conducted in Germany, examines the role of maternal soothing strategies to explain the association of maternal self-efficacy with infant regulation (crying and sleeping behavior). Questionnaire data of 150 mothers, living in Germany, with mixed ethnic and educational backgrounds were collected when infants were 3 and 7 months old. Two types of maternal soothing strategies were distinguished: close soothing, involving close physical and emotional contact, and distant soothing, involving physical and emotional distancing from the infant. A cross-sectional SEM at 3 months indicated that maternal self-efficacy is associated with reported infant regulation through distant soothing strategies. Low maternal self-efficacy was associated with frequent maternal use of distant soothing, which in turn was related to reported infant regulation problems, that is, non-soothability and greater crying frequency. Frequent use of close soothing was associated with reported infant sleeping behavior, that is, frequent night-time awakenings. A longitudinal SEM further indicated that the effects of close soothing persisted at least until the infants' age of 7 months. The study showed how low maternal self-efficacy, increased use of distant soothing, and reported early infant regulation problems are intertwined and that, due to their persisting positive effect on infant soothability, close soothing better supports infant development.

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.

Maternal Perceptions of Evidence-Based Early Childhood Sleep Health Promotion Recommendations: An Explanatory Sequential Study

OBJECTIVES

The purpose of this explanatory sequential design study was to better understand caregivers' perceptions about and interest in evidence-based early childhood sleep health promotion recommendations.

METHOD

A purposeful sample of mothers of 20 1-5-year-old children (10 children exhibiting optimal sleep and 10 children exhibiting insufficient/fragmented sleep) attending a preschool serving a low socio-economic (SES) status metropolitan community were invited to participate in qualitative interviews. Data were coded according to a grounded theory approach and themes were identified within the optimal and suboptimal sleeper groups.

RESULTS

Mothers reported different approaches to managing electronics by optimal/suboptimal sleeper group, with mothers of optimal sleepers limiting access to electronics more than mothers in the suboptimal sleep group. Other themes of sleep health practices did not differ meaningfully between groups.

CONCLUSIONS

Maternal perspectives about early childhood sleep health were similar across optimal and suboptimal sleepers on most elements of child sleep health. Managing child sleep was contextually influenced and these results highlight the complexities of how families living in lower SES environments perceive common sleep recommendations. Thus, sleep health education efforts should be tailored to the needs and values of specific families and communities.

The Feasibility of Screening for Sleep Problems in Early Childhood Education Programs

OBJECTIVES

Assess the feasibility and staff experience of screening for behavioral sleep problems (BSP) and sleep disordered breathing (SDB) in early childhood education (ECE) settings; examine BSP/SDB prevalence and caregivers' knowledge/attitudes, perception of child sleep problems, and sleep health engagement in this sample.

METHOD

Eight staff representatives from four ECE sites involved with sleep problem screening procedures within a larger RCT on ECE sleep health, discussed their experiences in a focus group; transcript content reviewed. A random subset of caregiver-child dyads (n = 59) from the four ECE sites completed sleep problem measures (BSP: Children's Sleep Habits Questionnaire, Short form [SF-CSHQ], Tayside Children's Sleep Questionnaire [TCSQ-sleep disturbance and difficulty] and SDB: Pediatric Sleep Questionnaire [PSQ], in addition to RCT measures (Parent Knowledge/Attitude/Self-efficacy/Beliefs survey and sleep health goals). Caregiver sleep health engagement was measured by the sleep health goals set.

RESULTS

ECE staff reported sleep problem screening as self-explanatory and doable but sometimes administratively burdensome. BSPs were identified in 44% (SF-CSHQ) to 63% (TCSQ-sleep disturbance) of children; SDBs in 13%. Only 11% of caregivers endorsed their child having a sleep "difficulty" (TCSQ). Sleep health goals were set by 85% of caregivers; 63% employed educational materials' language.

CONCLUSION

Sleep problem screening in ECE is feasible, and problems are elicited. While caregivers readily engage in setting healthy sleep goals, few endorse sleep as difficult. ECE education could improve caregiver understanding/recognition of 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.

Association between sleep duration and latency, nocturnal awakenings, and body mass index among infants

OBJECTIVE

To investigate the association between sleep duration, nocturnal awakenings, and sleep latency with body mass index (BMI) at six and 12 months of age.

METHODS

179 children from a birth cohort were enrolled. At six and 12 months of age, anthropometric data were obtained using standardized techniques and infants' mothers answered the Brief Infant Sleep Questionnaire for sleep data. The association of BMI with the independent variables (sleep duration, latency, and nocturnal awakenings) was assessed by linear regression models. Analyses were adjusted for potential confounders and a p-value<0.05 was adopted to define statistical significance.

RESULTS

For each additional hour of sleep duration, BMI was reduced by 0.15 kg/m² (95% confidence interval [CI] -0.28; -0.01; p=0.03) and each additional minute of sleep latency increased BMI by 0.01 kg/m² (95%CI -0.00; 0.03; p=0.02). These associations were independent of gestational age, child sex, birth weight, duration of exclusive breastfeeding, smoking during pregnancy, and mother's BMI, education, and marital status. Nocturnal awakenings showed no association with the outcome.

CONCLUSIONS

Our findings suggest that sleep duration and sleep latency time are associated with BMI in the first year of life. Insights into the influence of sleep early in life on weight status may be helpful to complement future nutritional recommendations and prevent and treat obesity.

The importance of sleep regularity: a consensus statement of the National Sleep Foundation sleep timing and variability panel

OBJECTIVE

To develop and present consensus findings of the National Sleep Foundation sleep timing and variability panel regarding the impact of sleep timing variability on health and performance.

METHODS

The National Sleep Foundation assembled a panel of sleep and circadian experts to evaluate the scientific evidence and conduct a formal consensus and voting procedure. A systematic literature review was conducted using the NIH National Library of Medicine PubMed database, and panelists voted on the appropriateness of 3 questions using a modified Delphi RAND/UCLA Appropriateness Method with 2 rounds of voting.

RESULTS

The literature search and panel review identified 63 full text publications to inform consensus voting. Panelists achieved consensus on each question: (1) is daily regularity in sleep timing important for (a) health or (b) performance? and (2) when sleep is of insufficient duration during the week (or work days), is catch-up sleep on weekends (or non-work days) important for health? Based on the evidence currently available, panelists agreed to an affirmative response to all 3 questions.

CONCLUSIONS

Consistency of sleep onset and offset timing is important for health, safety, and performance. Nonetheless, when insufficient sleep is obtained during the week/work days, weekend/non-work day catch-up sleep may be beneficial.

Sociodemographic, temporal and bedtime routine correlates of sleep timing and duration in South Asian and white children: A Born in Bradford study

Objective

The study aimed to examine sociodemographic, temporal and bedtime routine correlates of parent-reported sleep duration and timing in a biethnic sample of 18 month and 36 month old children from a disadvantaged location.

Methods

Between October 2010 and September 2012, parents completed a bespoke three day sleep diary when their child was approximately 18 months (n = 276) and 36 months of age (n = 262) (45.1% South Asian; 54.9% white). Parents reported their child's overnight sleep duration (h/day), the time their child fell asleep, their wake time and their child's bedtime and napping routines. Data were available at both time points for 135 children.

Results

In line with previous literature, South Asian children had shorter overnight sleep duration and later sleep and wake times than white children. In both ethnic groups, children slept and woke up later on weekends, and children went to bed earlier and slept longer in winter. In white children only, napping duration was associated with overnight sleep period. No significant associations were found between napping frequency and overnight sleep duration. Based on parent-reported data, children who consistently adhered to regular bedtimes and had set times for sleeping tended to go to sleep earlier, wake earlier and have longer overnight sleep.

Conclusions

The data showed parent-reported variation in sleep patterns between two ethnic groups within a single geographical and deprived area. It is important that researchers, clinicians and early years workers are considerate of cultural norms in sleep practices.

Focus Groups to Inform User-Centered Development of an eHealth Sleep Intervention for Adolescents: Perspectives of Youth with Insomnia Symptoms, with and without Pain

INTRODUCTION

Adolescence is a developmental stage that often coincides with increasing sleep problems. Focus groups were conducted to inform development of an adolescent eHealth sleep intervention by exploring opinions about (1) healthy sleep practices, and (2) using an eHealth intervention.

METHODS

Adolescents 14-18 years old experiencing symptoms of insomnia based on the Insomnia Sleep Index, with and without recurrent pain, and associated stakeholders (i.e., parents, school personnel, and health care providers) were recruited. Across six online focus groups, 24 adolescents with insomnia participated (14 pain-free, 10 with recurrent pain; 10 male, 14 female). Across seven online focus groups, 22 stakeholders participated, including 8 parents, 9 school professionals, and 5 health care providers (10 male, 8 female). Using a content analysis, subthemes were induced from transcripts.

RESULTS

Most healthy sleep practices were perceived as reasonable for adolescents to implement, except avoiding technology before bed and using bedrooms only for sleep. Three primary barriers to sleep practices were identified, including a variable schedule due to lifestyle factors, technology at night, and academics interfering with sleep, and only in the pain group, the barrier related to pain was identified. Content addressing adolescent-specific barriers was considered important to include in a sleep intervention. Desirable eHealth components included interactive features, videos, audio, and pictures to present information. A common barrier to using an eHealth sleep intervention was the program feeling too academic, with accessibility of the sleep information and strategies as a common facilitator.

CONCLUSIONS

This research represents the first step in a user-centered approach to developing an adolescent eHealth sleep intervention. These results provide insights from a range of perspectives on guiding adolescents to follow healthy sleep practices. Next, these findings will be integrated in the development of an eHealth intervention for adolescents with and without recurrent pain.

Contextual considerations in infant sleep: Offering alternative interventions to families

Infant sleep problems are one of the commonly reported reasons parents seek professional help, yet what constitutes a "sleep problem" depends on the models used to explain the development of infant sleep. The current models are based on research conducted in the western context where infant solitary sleeping is the norm. Parent-child co-sleeping is the norm in many cultures around the world. We argue that the primary focus of current research on parent-child interactions as the mediating context for the development of infant sleep problems has inherently made these models and ensuing interventions less sensitive and applicable to infant sleep problems in the context of co-sleeping families. When families present for help with infant sleep difficulties, extinction based behavioral interventions or interventions focused on reducing parental presence at bedtime are commonly recommended. These recommendations may not always align with cultural values and parenting practices of all families, therefore precluding these families from getting necessary help. In attempting to provide families with choices that depart from behavioral based interventions, this paper draws on research and adapts current models to propose an alternative to conceptualize perceptions of infant sleep problems that may be sensitive to and applied across various cultural and personal contexts. We attempt to provide a rationale for interventions that are inclusive and sensitive to families where reduced parental nighttime responsiveness may not be a preferred choice.

Nocturnal sleep duration trajectories in early childhood and school performance at age 10 years

Sleep plays a fundamental role in brain development and resultant functions. The aim was to verify whether nocturnal sleep duration during early childhood has long-term associations with academic achievement at age 10 years. The present study is part of the Quebec Longitudinal Study of Child Development, a representative cohort of infants born in 1997-1998 in the province of Quebec, Canada. Children with known neurological conditions were excluded from this cohort. Four trajectories of parent-reported nocturnal sleep duration at ages 2.5, 3, 4, 5 and 6 years were determined using a SAS procedure named PROC TRAJ. Sleep duration at age 10 years was also reported. Teachers provided data on academic performance when the children were age 10 years. These data were available for 910 children (430 boys, 480 girls; 96.6% Caucasians). Univariate and multivariable logistic regressions were performed using SPSS. Children who slept less than 8 hr per night at 2.5 years but normalized later on (Traj1) had three-five times the odds of having grades below the class average in reading, writing, mathematics and science compared with children who slept sufficiently (Traj3-4: 10-11 hr per night). Children who slept about 9 hr per night throughout childhood (Traj2) had two-three times the odds of being below the class average in mathematics and science. Sleep duration at age 10 years was not correlated with the academic performance. These results point to the presence of a very important early period during which sufficient sleep is needed to fine-tune the functions necessary for academic achievement later on.

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.

Bridging the gap: leveraging implementation science to advance pediatric behavioral sleep interventions

STUDY OBJECTIVES

This review synthesizes the pediatric behavioral sleep intervention (BSI) evidence base, summarizes challenges in translating BSIs from research to practice, and provides recommendations for integrating implementation science methods to advance pediatric BSI research.

METHODS

We briefly review the common behavioral sleep disturbances among youth, discuss the pediatric BSIs with well-established evidence, and identify gaps in pediatric BSI research. We then identify contributors to the dearth of research evaluating pediatric BSIs in accessible settings and present a model for applying implementation science strategies to address identified gaps across the continuum of translational research.

RESULTS

Relatively few BSI trials include older children and adolescents. Similarly, there is limited research evaluating BSIs among racially and ethnically minoritized children and families and/or those of lower socioeconomic status backgrounds. Access to scalable and easily disseminable tools to treat pediatric sleep disturbances early in their development is crucial for promoting positive child outcomes. To address these gaps, researchers should apply implementation science theories, models, and frameworks to design new interventions for implementation, adapt existing interventions with end users and settings in mind, conduct hybrid effectiveness-implementation trials, and test implementation strategies.

CONCLUSIONS

Given the prevalence and consequences of poor sleep across developmental periods, pediatric BSIs must be effective as well as adaptable, scalable, and easily disseminable. Implementation science theories, models, and frameworks can enhance access to, engagement in, and the implementation and dissemination of scalable BSIs across diverse pediatric care settings and heterogeneous populations.

Sleep ecology, objective sleep characteristics and behavior problems in preschoolers referred to child protection services: An exploratory study

BACKGROUND

Exposure to environmental risk factors increases the negative impact maltreatment has on children's development. Sleep ecology (i.e., sleep hygiene and home sleeping conditions) can be one of these factors. Poor sleep hygiene and suboptimal home sleeping conditions can alter sleep characteristics, which in turn, may lead to behavior problems (BPs), highly prevalent in maltreated preschoolers.

OBJECTIVES

Describe sleep ecology in maltreated preschoolers and explore associations between their sleep ecology, objective sleep characteristics and BPs.

METHOD

Parents (n = 22) completed the Children's Sleep Hygiene Scale (CSHS), and a sleep environment questionnaire to document sleep ecology. Children wore an actigraph to record objective sleep characteristics. Parents completed the Behavioral Assessment Scale for Children (BASC-2) to assess children's BPs. Descriptive and correlational analyses were performed.

RESULTS

Most of the parents (90.5 %) reported adequate sleep hygiene. However, 20 parents (95.2 %) reported suboptimal home sleeping conditions. Better physiological and overall sleep hygiene were related to earlier sleep onset. Better emotional sleep hygiene was associated with shorter nighttime awakenings and better sleep efficiency. Later sleep onset was associated with lower anxiety, and longer 24-hour sleep duration with higher somatization. Better physiological sleep hygiene was associated with less depression, and better emotional sleep hygiene with less hyperactivity.

CONCLUSION

This study showed that sleep hygiene could be associated with maltreated preschoolers' sleep characteristics and BPs, and that their home sleeping conditions may be of concern. Associations between sleep ecology, objective sleep characteristics and BPs deserve to be better understood, and further explored.

Improving Children's Sleep Habits Using an Interactive Smartphone App: Community-Based Intervention Study

BACKGROUND

Sleep problems are quite common among young children and are often a challenge for parents and a hinderance to children's development. Although behavioral therapy has proven effective in reducing sleep problems in children, a lack of access to professionals who can provide effective support is a major barrier for many caregivers. Therefore, pediatric sleep experts have begun developing apps and web-based services for caregivers. Despite the substantial influence of cultural and familial factors on children's sleep, little effort has gone into developing cultural or family-tailored interventions.

OBJECTIVE

This study aimed to examine the effectiveness of the interactive smartphone app "Nenne Navi," which provides culturally and family-tailored suggestions for improving sleep habits in young Japanese children through community-based long-term trials. The study also aimed to investigate the association between app-driven improvements in sleep and mental development in children.

METHODS

This study adopted a community-based approach to recruit individuals from the Higashi-Osaka city (Japan) who met ≥1 of the following eligibility criteria for sleep problems: sleeping after 10 PM, getting <9 hours of nighttime sleep, and experiencing frequent nighttime awakenings. A total of 87 Japanese caregivers with young children (mean 19.50, SD 0.70 months) were recruited and assigned to the app use group (intervention group) or the video-only group (control group). Both groups received educational video content regarding sleep health literacy. The caregivers in the intervention group used the app, which provides family-tailored suggestions, once per month for 1 year.

RESULTS

A total of 92% (33/36) of the caregivers in the app use group completed 1 year of the intervention. The participants' overall evaluation of the app was positive. The wake-up time was advanced (base mean 8:06 AM; post mean 7:48 AM; F_1,65=6.769; P=.01 and sleep onset latency was decreased (base mean 34.45 minutes; post mean 20.05 minutes; F_1,65=23.219; P<.001) significantly in the app use group at the 13th month compared with the video-only group. Moreover, multiple regression analysis showed that decreased social jetlag (β=-0.302; P=.03) and increased sleep onset latency SD (β=.426; P=.02) in children predicted a significant enhancement in the development of social relationships with adults. At 6 months after the completion of the app use, all the caregivers reported continuation of the new lifestyle.

CONCLUSIONS

The present findings suggest that the app "Nenne Navi" has high continuity in community use and can improve sleep habits in young Japanese children and that interventions for sleep habits of young children may lead to the enhancement of children's social development. Future studies must focus on the effectiveness of the app in other regions with different regional characteristics and neuroscientific investigations on how changes in sleep impact brain development.

Longitudinal trends in parent-reported child sleep, physical activity, and screen use during the COVID-19 pandemic in New York City

Objective

To examine trends in child sleep, physical activity, and screen use during the COVID-19 pandemic in New York City with a prospective, longitudinal online survey of parents recruited from a large medical center.

Methods

Data was collected Spring 2020 ("Complete Shutdown") and Fall 2020 ("Partial Shutdown"). Outcomes were parental perceptions about changes in child sleep, physical activity, and screen time compared to before COVID-19; and contemporaneous measures of these child behaviors. We report contemporaneous responses and paired analyses to describe longitudinal changes.

Results

Two hundred seventy-seven participants were surveyed during Complete Shutdown and 227 (81.9%) filled out a follow-up survey during Partial Shutdown. The largest percentage of parents at both time points perceived no change in child sleep, decreases in child exercise, and increases in child screen time. In paired analyses, perceptions shifted toward less sleep, more physical activity and less screen time from Complete Shutdown to Partial Shutdown.

Conclusion

COVID-19 had negative impacts on child health behaviors that did not resolve over a 6-month period despite partial reopenings.

Promoting Sleep Duration in the Pediatric Setting Using a Mobile Health Platform: A Randomized Optimization Trial

Objective

Determine the optimal combination of digital health intervention component settings that increase average sleep duration by ≥30 minutes per weeknight.

Methods

Optimization trial using a 25 factorial design. The trial included 2 week run-in, 7 week intervention, and 2 week follow-up periods. Typically developing children aged 9-12y, with weeknight sleep duration <8.5 hours were enrolled (N=97). All received sleep monitoring and performance feedback. The five candidate intervention components (with their settings to which participants were randomized) were: 1) sleep goal (guideline-based or personalized); 2) screen time reduction messaging (inactive or active); 3) daily routine establishing messaging (inactive or active); 4) child-directed loss-framed financial incentive (inactive or active); and 5) caregiver-directed loss-framed financial incentive (inactive or active). The primary outcome was weeknight sleep duration (hours per night). The optimization criterion was: ≥30 minutes average increase in sleep duration on weeknights.

Results

Average baseline sleep duration was 7.7 hours per night. The highest ranked combination included the core intervention plus the following intervention components: sleep goal (either setting was effective), caregiver-directed loss-framed incentive, messaging to reduce screen time, and messaging to establish daily routines. This combination increased weeknight sleep duration by an average of 39.6 (95% CI: 36.0, 43.1) minutes during the intervention period and by 33.2 (95% CI: 28.9, 37.4) minutes during the follow-up period.

Conclusions

Optimal combinations of digital health intervention component settings were identified that effectively increased weeknight sleep duration. This could be a valuable remote patient monitoring approach to treat insufficient sleep in the pediatric setting.

Sleep Patterns and School Readiness of Pre-Kindergarteners from Racially and Ethnically Diverse, Low-Income Backgrounds

OBJECTIVE

To explore patterns in parent-reported child sleep health and to investigate connections between such patterns and school readiness for newly enrolled prekindergarten (PreK) attendees from racially and ethnically diverse, low-income backgrounds.

STUDY DESIGN

In a secondary analysis from a larger multiple-cohort longitudinal observational study of prekindergartners in low-income families, parental reports of sleep health for 351 children (mean age, 52.8 ± 3.5 months) during the first month of PreK were analyzed. Children also had completed direct assessments measuring language, literacy, mathematics, and executive functioning, and teachers rated children's social-emotional-behavioral competencies and approaches to learning at PreK entry. We performed latent class analyses to identify patterns in sleep health and used regression models to examine concurrent associations between child sleep health patterns and school readiness competencies across 6 domains: language, literacy, mathematics, executive functioning, social-emotional-behavioral, and approaches to learning.

RESULTS

Two classes emerged reflecting more and less desirable patterns of sleep health. Children classified in the earlier, longer, consistent sleep health class (87% of children) experienced earlier bedtimes, longer night-time sleep durations, more consistent sleep routines, less caffeine consumption ≤3 hours before bedtime, and scored higher on a direct assessment of expressive vocabulary and on teacher-reported measures of social-emotional-behavioral competencies and learning approaches than their peers in the later, shorter, inconsistent sleep health class (13% of children).

CONCLUSIONS

Consistent sleep routines and more optimal sleep health may serve as a protective mechanism for the language development, social-emotional-behavioral regulation, and approaches to learning of PreK from racially and ethnically diverse, low-income backgrounds. Clinician-parent discussions regarding optimal sleep health may provide key opportunities for targeted education that promotes school readiness skill development.

Promoting children's sleep health: Intervention Mapping meets Health in All Policies

Background

To design a comprehensive approach to promote children's sleep health in Amsterdam, the Netherlands, we combined Intervention Mapping (IM) with the Health in All Policies (HiAP) perspective. We aimed to create an approach that fits local infrastructures and policy domains across sectors.

Methods

First, a needs assessment was conducted, including a systematic review, two concept mapping studies, and one cross-sectional sleep diary study (IM step 1). Subsequently, semi-structured interviews with stakeholders from policy, practice and science provided information on potential assets from all relevant social policy sectors to take into account in the program design (HiAP and IM step 1). Next, program outcomes and objectives were specified (IM step 2), with specific objectives for policy stakeholders (HiAP). This was followed by the program design (IM step 3), where potential program actions were adapted to local policy sectors and stakeholders (HiAP). Lastly, program production (IM step 4) focused on creating a multi-sector program (HiAP). An advisory panel guided the research team by providing tailored advice during all steps throughout the project.

Results

A blueprint was created for program development to promote children's sleep health, including a logic model of the problem, a logic model of change, an overview of the existing organizational structure of local policy and practice assets, and an overview of policy sectors, and related objectives and opportunities for promoting children's sleep health across these policy sectors. Furthermore, the program production resulted in a policy brief for the local government.

Conclusions

Combining IM and HiAP proved valuable for designing a blueprint for the development of an integrated multi-sector program to promote children's sleep health. Health promotion professionals focusing on other (health) behaviors can use the blueprint to develop health promotion programs that fit the local public service infrastructures, culture, and incorporate relevant policy sectors outside the public health domain.

Effect of illuminated musical mobile on sleep quality of children hospitalized in pediatric emergency departments

PURPOSE

The aim of this study is to evaluate the effect of an illuminated musical mobile on the sleep quality of children hospitalized in a pediatric emergency department.

DESIGN AND METHODS

In this randomized controlled study, 124 children presenting to a pediatric emergency department who met the inclusion criteria were included in the study. Patients were randomized into two equal groups. In the intervention group, an illuminated musical mobile was used to help facilitate sleep. In the control group, routine sleep routines were continued. Groups were compared according to sleep quality as evaluated by mothers' observations. Evaluation was performed twice (before intervention - 1st day of hospitalization and on the intervention day - 2nd day of hospitalization).

RESULTS

Average age of children was 1.86 ± 0.78 years. On the intervention day, nighttime sleep duration was longer in the intervention group (p < .0001). Also, the frequency of spontaneous awakening (p < .0001), time to fall asleep after spontaneous awakening (p < .0001) and sleep time problems (p < .0001) were less in the intervention group. CONCLUSıONS: An illuminated musical mobile was used for the first time in the pediatric emergency department and was found to be effective in improving the sleep quality of hospitalized children aged between 1 and 3 years.

PRACTICE IMPLICATIONS

During hospitalization, children's sleep quality can be increased by using methods and objects suitable for the child's developmental level.

Nonpharmacological Interventions to Lengthen Sleep Duration in Healthy Children: A Systematic Review and Meta-analysis

Importance

Adequate sleep duration is necessary for many aspects of child health, development, and well-being, yet sleep durations for children are declining, and effective strategies to increase sleep in healthy children remain to be elucidated.

Objective

To determine whether nonpharmaceutical interventions to improve sleep duration in healthy children are effective and to identify the key components of these interventions.

Data Sources

CENTRAL, MEDLINE, Embase, PsycINFO, Web of Science Core collection, ClinicalTrials.gov, and WHO trials databases were searched from inception to November 15, 2021.

Study Selection

Randomized clinical trials of interventions to improve sleep duration in healthy children were independently screened by 2 researchers. A total of 28 478 studies were identified.

Data Extraction and Synthesis

Data were processed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) reporting guideline. Random-effects meta-analytic models were used to estimate pooled effect sizes.

Main Outcomes and Measures

Difference in sleep duration, measured in minutes.

Results

A total of 13 539 child participants from 45 randomized clinical trials were included. Of these, 6897 (50.9%) were in the intervention group and 6642 (49.1%) in the control group, and the mean age ranged from 18 months to 19 years. Pooled results indicate that sleep interventions were associated with 10.5 minutes (95% CI, 5.6-15.4) longer nocturnal sleep duration. There was substantial variation between trials. Sources of variation that were not associated with the study effect size included age group, whether the population was identified as having a sleep problem or being at a socioeconomic disadvantage (eg, coming from a low-income family or area), method of assessment of sleep duration (objective vs subjective), location of intervention delivery (home vs school), whether interventions were delivered in person or used parental involvement, whether behavioral theory was used, environmental change, or had greater or lower intensity. Interventions that included earlier bedtimes were associated with a 47-minute sleep extension (95% CI, 18.9-75.0; 3 trials) compared with remaining studies (7.4 minutes; 95% CI, 2.9-11.8; 42 trials) (P = .006 for group difference). Trials of shorter duration (6 months or less) had larger effects.

Conclusions and Relevance

Interventions focused on earlier bedtimes may offer a simple, pragmatic, effective way to meaningfully increase sleep duration that could have important benefits for child health.

Children with neurodevelopmental disorders: how do they sleep?

PURPOSE OF REVIEW

In this review we summarized the available evidence on sleep disorders in children with neurodevelopmental disorders (NDDs) in particular: intellectual disability (including some genetic conditions such as Prader-Willi Syndrome, Smith-Magenis Syndrome), Autism spectrum disorder, attention-deficit/hyperactivity disorder (ADHD), Developmental Coordination Disorder, language disorders, and specific learning disorders.

RECENT FINDINGS

Children with NDDs frequently suffer from sleep disturbances, with a higher prevalence than that of the general pediatric population.

SUMMARY

These problems tend to be chronic and may cause additional cognitive and behavioral difficulties, often affecting the whole family's well-being. Sleep behaviors are also related to other important developmental skills, such as attention and listening. Investigating sleep disorders in children with NDDs is therefore crucial in clinical practice. For a systematic approach in clinical practice, we propose the use of a short and easy to remember sleep screening tool.

Sleep terrors-A parental nightmare

Sleep terrors (STs) are sleep disorders characterized by abrupt arousal from sleep with autonomic hyperactivity and inappropriate behavior. Though a common condition in childhood that usually affects children between 4 and 12 years of age, STs, however, may be present even in adulthood. The exact etiology of STs is not known yet, however, several hypotheses have been proposed over the years, identifying some potential genetic, neurodevelopmental, or other causes. Nevertheless, a useful pathophysiological model identified a common cascade of predisposing, priming, and precipitating factors, which could help to explain and sometimes prevent STs. Establishing a correct diagnosis is mandatory for appropriate management, as several conditions (such as other parasomnias or nocturnal seizures) may mimic STs. Furthermore, we also described some conditions which can be comorbid to STs, like some medical or psychological disorders. A number of treatment options have been proposed, ranging from only sleep hygiene practices to pharmacological therapies; we reviewed some of the most prominent ones. In spite of the fact that STs have long been considered benign disorders, which tend to reduce spontaneously over the years, they may have unexpected consequences on the child but also on the caregivers.

The physical home environment and sleep: What matters most for sleep in early childhood

The physical home environment is thought to play a crucial role in facilitating healthy sleep in young children. However, relatively little is known about how various features of the physical home environment are associated with sleep in early childhood, and some of the recommendations clinicians make for improving child sleep environments are based on limited research evidence. The present study examined how observer and parent descriptions of the child's physical home environment were associated with child sleep, measured using actigraphy and parent's reports, across a year in early childhood. The study used a machine learning approach (elastic net regression) to specify which aspects of the physical home environment were most important for predicting five aspects of child sleep, sleep duration, sleep variability, sleep timing, sleep activity, and latency to fall asleep. The study included 546 toddlers (265 females) recruited at 30 months of age and reassessed at 36 and 42 months of age. Poorer quality physical home environments were associated with later sleep schedules, more variable sleep schedules, shorter sleep durations, and more parent-reported sleep problems in young children. The most important environmental predictors of sleep were room sharing with an adult, bed sharing, and quality of both the child's sleep space and the wider home environment.

Effect of the INSIGHT Firstborn Parenting Intervention on Secondborn Sleep

BACKGROUND AND OBJECTIVES

The Intervention Nurses Start Infants Growing on Healthy Trajectories (INSIGHT) responsive parenting (RP) intervention for first-time mothers improved firstborn infant sleep compared with controls. The goals of this analysis were to test intervention spillover effects on secondborn siblings and examine birth order differences in infant sleep.

METHODS

Secondborns (n = 117) of INSIGHT mothers were enrolled in an observational cohort, SIBSIGHT. The Brief Infant Sleep Questionnaire was collected at 3, 16, and 52 weeks. Generalized linear mixed models assessed differences among secondborns by firstborn randomization, as well as birth order differences at 16 and 52 weeks.

RESULTS

The RP group secondborns slept 42 minutes longer at night (95% confidence interval [95% CI]: 19-64) and 53 minutes longer total (95% CI: 17-90) than control secondborns. RP secondborns were more likely to self-soothe to sleep (odds ratio [OR] = 2.0, 95% CI: 1.1-3.7) and less likely to be fed back to sleep after waking (OR = 0.5, 95% CI: 0.3-0.9) than secondborns of control mothers. RP secondborns were more likely to have a bedtime ≤8 pm at 3 (OR = 2.9, 95% CI: 1.1-7.7) and 16 weeks (OR = 4.7, 95% CI: 2.0-11.0). Few differences in sleep parenting practices were observed when comparing siblings within families. Secondborns slept 37 minutes longer than firstborns at 16 weeks (CI: 7-67, P = .03).

CONCLUSIONS

The INSIGHT RP intervention for first-time mothers had a spillover effect to secondborns, positively impacting sleep duration and behaviors. Intervening with first-time mothers benefits both firstborns and subsequent children.

Primary School Children's Sleep Habits: Association with Socioeconomic Factors and Physical Activity Habits

Sleep disorders have significant health impacts and affect children’s performance and wellbeing. This study aims to characterise the sleep habits of Portuguese primary school children considering socioeconomic factors, daily lifestyle, presence of electronic devices in the bedrooms, and the practice of physical and sports activity (PSA) and to identify clinical factors that may be related to a child’s insufficient sleeping time. This study involved 1438 primary students. Sleep habits and problems were assessed using the short version of the Children’s Sleep Habits Questionnaire (CSHQ). The mean sleep duration was 9 h 37 min/ per night (SD = 44 min). The prevalence of global sleep disturbances was 25.8%. The main factors we identified to be positively associated with a child’s sleep deficit (i.e., <10 h) were: being older than 7 years, living further away from school, having electronic devices in the bedroom, going to bed and eating dinner later, less daily time of PSA, and having higher scores on the sleep duration subscales. Sleeping and eating habits, electronic devices in the bedroom, and a low level of engagement with PSA are associated with children’s sleep disturbance and shorter sleep duration.

Sleep Deficiency in Young Children

There is growing public health concern about the high prevalence of sleep deficiency in early childhood and the associated risk for sleep-associated poor health outcomes, including metabolic, cardiovascular, and mental health. The recent shift to conceptualize sleep health as a multidimensional construct, influenced by socioecological factors, highlights the potential role of sleep in health disparities. Understanding the development of sleep health and the emergence of sleep disorders in early life is a current priority in pediatric sleep research. Future behavioral sleep interventions should consider the multiple socioecological influences on children's sleep health and be tested using inclusive sampling methods.

Effectiveness of behavioral sleep interventions on children's and mothers' sleep quality and maternal depression: a systematic review and meta-analysis

This systematic review and meta-analysis was conducted to investigate the effectiveness of behavioral sleep interventions (BSIs) on the number of child night awakenings, and maternal sleep quality and depression. The search followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines (PRISMA) using PubMed, CINAHL, Cochrane, and EMBASE databases and retrieved studies published until April 2021. We calculated the odds ratios (ORs) and 95% confidence intervals (CIs) for child sleep problems, and the mean differences (MD) and 95% CI for the number of child night awakenings, and maternal sleep quality and depression. Ten studies of 1628 initial searched were included in the final analysis. Two of the 10 studies were divided into two subgroups by participants and intervention type; thus, 12 subgroups were included in the meta-analysis. BSIs significantly reduced child sleep problems (OR 0.51; 95% CI 0.37–0.69) and improved maternal sleep quality (MD − 1.30; 95% CI − 1.82 to − 0.77) in the intervention group. There were no significant differences in the number of child night awakenings and maternal depression between the two groups. More RCTs to examine the effect of BSIs considering children’s age, duration of intervention, and outcome measuring time points are needed.

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.

Sleep Well! An adapted behavioral sleep intervention implemented in urban primary care

STUDY OBJECTIVES

To describe the adaptation, feasibility, and initial outcomes of Sleep Well!, an intervention for early childhood insomnia and insufficient sleep, designed for families from lower-socioeconomic status (SES) backgrounds presenting to large metropolitan primary care sites.

METHODS

Fifteen caregiver-child dyads (caregivers: 92.3% mothers; 80.0% Black; 53.3% ≤125% US poverty level; children: 73.3% female; 86.7% Black; M age = 3.0 years) participated this multi-method, single-arm trial. A family advisory board of caregivers (N = 4) and a clinician advisory board of sleep experts, primary care clinicians, and psychologists (N = 13) provided intervention feedback throughout the pilot. Most adaptations were related to intervention delivery methods, with some related to sleep strategies. At post-intervention, caregivers completed surveys on intervention acceptability and cultural humility (primary outcomes) and completed semi-structured interviews. Caregivers also reported on child sleep pre- and post-intervention.

RESULTS

Thirteen (86.6%) families completed Sleep Well! and 12 (80.0%) completed pre- and post-intervention measures. Caregivers reported strong intervention acceptability and cultural humility. There were pre-to-post reductions in child sleep problems, bedroom electronics, sleep onset latency, and night awakening frequency and duration. Nighttime sleep duration and overall insufficient sleep also improved. Qualitative data also showed strong intervention acceptability and perceived flexibility, with few participation barriers.

CONCLUSIONS

A brief, early childhood behavioral sleep intervention delivered in primary care with families from primarily lower-SES and/or racially minoritized backgrounds is feasible to implement, with strong retention rates, acceptability, and perceptions of cultural humility. Child sleep improvements are positive, and warrant replication in a randomized controlled trial.

Correlates of inadequate sleep health among primary school children

The aim of the present study was to explore potential factors of inadequate sleep health (i.e. sleep duration, quality, and timing) of school-aged children. Data were collected among 382 primary school children (aged 4-13 years) and their parents. Personal characteristics (i.e. age, sex), individual lifestyle behaviours (i.e. screen use, sleep hygiene behaviour), social and community factors (i.e. parental sleep-related practices, parental barriers, perceived ethnicity), and living conditions (i.e. parental educational level, sleep environment) were assessed with a parental questionnaire. Sleep duration, quality, and timing were assessed with a sleep diary. Associations were analysed using linear mixed models and logistic regression analyses. In total, 332 children, with a mean (range) age of 7.5 (4-13) years, were included in the analyses. The mean sleep duration was 632 min/night, the mean sleep quality score was 40, on a scale from 10 to 50, and 25% had a bedtime that varied >40 min between weekdays. Factors negatively associated with children's sleep health included older age, perceived non-Dutch cultural background, lower parental pre-sleep emotional support, the parental barrier to get their child to bed on time when siblings have a later bedtime, high parental educational level, sleeping in a darkened bedroom, and being brought to bed after falling asleep. On average, children in the present study had adequate sleep health. The factors found to be associated with children's sleep health are useful for future healthy sleep research and intervention development.

Sleep in children and adolescents with juvenile idiopathic arthritis: a systematic review and meta-analysis of case-control studies

STUDY OBJECTIVES

Juvenile idiopathic arthritis (JIA) is one of the most common pediatric rheumatic disease. However, sleep alteration associated with this auto-immune disease remain unclear. We aimed in this systematic review and meta-analysis to compare sleep duration, quality, and architecture in JIA subjects with those in their healthy peers.

METHODS

Systematic search performed in PubMed, EMBase, Cochrane, and PsycINFO databases included 19 studies in the qualitative synthesis of which 10 met the inclusion criteria for the meta-analysis.

RESULTS

Pooled results from subjective methods indicated pronounced sleep disturbances and complaints in youth with JIA compared with their healthy counterparts. This was further confirmed by Increased difficulty maintaining sleep (wake after sleep onset; SMD: -0.69; CI: -1.29; -0.09, p =0.02) and a tendency to increased difficulty initiating sleep (sleep onset latency; SMD: -0.29; CI: -0.60; 0.03, p =0.07). There were no remarkable differences in sleep duration or sleep architecture between JIA patients and healthy controls. High heterogeneity was found for several outcomes. This could be explained by the different methods used as well as associated sleep disorders, medication and comorbidities.

CONCLUSIONS

Although included studies were methodologically diverse, the summarized results of our review and meta-analysis bring evidence that children with JIA present more fragmented sleep compared to healthy peers. Thereby, the implementation of strategies to manage and improve sleep in this population are needed and might have a beneficial effect on the symptoms and functions of JIA.

Sleep habits and weight status in Brazilian children aged 4-6 years of age: the PREDI study

OBJECTIVES

To evaluate the association of sleep habits with the weight status of children aged 4-6 years.

METHODS

Data were obtained from the PREDI Study, a Brazilian birth cohort study. The current study was carried out in the homes of the participants during two follow-ups: 2016/17 and 2018. The participants were submitted to anthropometric assessment and demographic, socioeconomic and sleep data were obtained. The child's sleep habits were self-reported by the mother or caregiver on the day of the visit and included information on the following sleep habits during the past week: bedtime routine, rhythmicity, and separation affect determined with the Sleep Habits Inventory for Preschool Children and the Sleep Habits Inventory. Logistic regression and gamma-log regression analyses were used to examine the association of sleep habits with excess body weight of children in the two follow-ups according to sex.

RESULTS

Of the 217 and 185 children included in 2016/17 and 2018, respectively, 66 (30.6%) and 48 (25.9%) had a BMI >85th percentile at 4-6 years, respectively. The median rhythmicity score was higher in children with excess body weight (p = 0.05). Adjusted analysis showed that rhythmicity was associated with excess body weight of girls at ages 4-5 years (OR = 1.42, 95% CI: 1.09-1.86, p = 0.009) and 6 years (OR = 1.32, 95% CI: 1.06-1.65, p = 0.015), even after adjustment for other important covariates. Additionally, the sleep habit "separation affect" was inversely associated with the child's BMI in boys (β = -0.005, 95% CI: -0.010-0.000, p = 0.037).

CONCLUSIONS

In the present study, rhythmicity problems were associated with increased odds of girls aged 4-6 years having excess body weight. These results are important from a public health perspective since strategies aimed at preventing excess body weight in children need to consider the child's sleep quality as a potential risk factor, especially rhythmicity.

Bedtime Schedules and Sleep Regulation among Children of Incarcerated Parents

OBJECTIVES

To investigate variation by parental incarceration history in the bedtime schedules set for elementary-age children and whether sleep was effectively regulated.

STUDY DESIGN

We ran multivariate regression models estimating the relationship between parental incarceration and 6 measures of bedtime schedules and sleep regulation. Our sample included 9-year-olds in the Fragile Families and Child Wellbeing Study (n = 3246), a survey of children born in large US cities between 1998 and 2000 that has an oversample of unmarried mothers.

RESULTS

Children's bedtime schedules did not differ at a statistically significant level by parental incarceration history, but children of ever- vs never-incarcerated fathers had lower odds of consistently adhering to a set bedtime. Children of ever-incarcerated fathers also slept for less time on average than did children of never-incarcerated fathers, and they had lower odds of obtaining sufficient sleep. Bedtime consistency partly mediated the association between paternal incarceration and total sleep duration.

CONCLUSIONS

Although caregivers set appropriate bedtime schedules for children of ever-incarcerated fathers, consistent adherence to those schedules may be particularly challenging given the structural hardships of paternal incarceration. Policymakers, researchers, and practitioners working to improve sleep among children of incarcerated fathers should focus on helping families to develop strategies for implementing bedtime schedules as consistently and effectively as possible.

The Impact of Anxiety on Behavioral Sleep Difficulties and Treatment in Young Children: A Review of the Literature

Sleep difficulties are a common pediatric complaint, and the majority of these sleep difficulties are behavioral in nature (e.g., difficulties initiating or maintaining sleep). Although research supports behavioral interventions to improve sleep in young children with behavioral sleep difficulties, anxiety and child distress are common in this age range and these factors can impact treatment outcomes directly (e.g., increased distress and resistance at bedtime) and indirectly (e.g., poor parental compliance with behavioral strategies). Anxiety is an important aspect of treatment in adolescents and adults with behavioral sleep difficulties, but this factor is rarely considered in the literature for younger children. Thus, this manuscript reviews the literature on anxiety as it relates to behavioral sleep difficulties in young children (i.e., the preschool and surrounding age range), provides an overview of empirically supported behavioral intervention and research incorporating anxiety into behavioral sleep treatments, and provides recommendations and future directions for continuing to advance the literature and treatment in this area.

Multi-Organ Dysfunction in Cerebral Palsy

Cerebral Palsy (CP) describes a heterogenous group of non-progressive disorders of posture or movement, causing activity limitation, due to a lesion in the developing brain. CP is an umbrella term for a heterogenous condition and is, therefore, descriptive rather than a diagnosis. Each case requires detailed consideration of etiology. Our understanding of the underlying cause of CP has developed significantly, with areas such as inflammation, epigenetics and genetic susceptibility to subsequent insults providing new insights. Alongside this, there has been increasing recognition of the multi-organ dysfunction (MOD) associated with CP, in particular in children with higher levels of motor impairment. Therefore, CP should not be seen as an unchanging disorder caused by a solitary insult but rather, as a condition which evolves over time. Assessment of multi-organ function may help to prevent complications in later childhood or adulthood. It may also contribute to an improved understanding of the etiology and thus may have an implication in prevention, interventional methods and therapies. MOD in CP has not yet been quantified and a scoring system may prove useful in allowing advanced clinical planning and follow-up of children with CP. Additionally, several biomarkers hold promise in assisting with long-term monitoring. Clinicians should be aware of the multi-system complications that are associated with CP and which may present significant diagnostic challenges given that many children with CP communicate non-verbally. A step-wise, logical, multi-system approach is required to ensure that the best care is provided to these children. This review summarizes multi-organ dysfunction in children with CP whilst highlighting emerging research and gaps in our knowledge. We identify some potential organ-specific biomarkers which may prove useful in developing guidelines for follow-up and management of these children throughout their lifespan.

Parenting Practices, Bedtime Routines, and Consistency: Associations with Pediatric Sleep Problems

OBJECTIVES

Investigate the direct and moderating effects of daytime parenting practices on the relationship between bedtime routines and pediatric sleep problems.

METHODS

A community sample of 407 parents with children 2-10 years old completed measures of parenting practices (i.e., laxness and over-reactivity) and bedtime routines (i.e., consistency and reactivity to changes in routines). Sleep problems (i.e., severity and signaled night waking) were assessed by a parent-report questionnaire and sleep diaries.

RESULTS

Higher parenting laxness (β = .13) and less bedtime routine consistency (β = -.34) significantly predicted sleep problem severity. Laxness moderated the relationship between bedtime reactivity and sleep problem severity: when bedtime reactivity was high, higher parental laxness was associated with more severe sleep problems.

CONCLUSIONS

Daytime parenting practices are important to consider when children are reactive to changes in bedtime routines, as permissive or inconsistent daytime parenting practices were found to be associated with more severe sleep problems. Future research should examine the effects of parenting practices and bedtime routines on problematic signaled night waking in a clinical sample of children.

Opportunities to improve sleep of children exposed to interpersonal violence: A social-ecological perspective

Over 25% of U.S. children are witness to traumatic intrafamilial or community violence each year, and sleep medicine and developmental research jointly suggest that trauma-exposed youth experience more sleep disturbance than their non-exposed counterparts. Sleep medicine literature emphasizes physical and social environmental factors affecting sleep, and trauma literature underscores children's seeking out physically and emotionally safe and predictable environments during trauma recovery. This study employed a hermeneutic phenomenological framing to explore the lived experiences of 65 violence-exposed children and families, and to examine how youths' social and physical sleep environments facilitated or impeded sleep in the aftermath of trauma. Children's sleep experiences following violence exposure shared two primary essences of experience: a) navigating external threats that agitated sleep after trauma; and b) exercising agency over sleep and related environments to restabilize emotional security. Clinicians and social services coordinators working with children and families are uniquely positioned to indicate sleep assessments as part of treatment following trauma, and to also facilitate identification of tangible, sleep-supportive and changeable factors in sleep environments.

Parents' Nonstandard Work and Children's Sleep: The Mediating Role of Bedtime Routines

OBJECTIVE

The present study examined if caregivers' long work hours or shift work are related to children's sleep duration through the disruption of bedtime routines.

METHOD

Work hours and schedules, bedtime routines and sleep (actigraph assessments) were examined in a sample of 250 caregivers and their preschool children.

RESULTS

Results revealed that consistent bedtime routines mediated the relationship between caregiver's work and children's sleep, such that longer hours and shift work predicted fewer routines that, in turn, predicted less child sleep.

CONCLUSION

These results point to the crucial role of bedtime routines as a promising point of intervention for working parents. While caregivers may not be able to change their work hours or schedules, they can create more stable and consistent bedtime routines to mitigate the negative effects of their work on children's sleep.

The Effectiveness of Bilateral Alternating Tactile Stimulation for Improving Sleep in Children with Sensory over-Responsivity

The objective of this study was to explore the effectiveness of Touchpoints™ on improving sleep in children with sensory over-responsivity, specifically, whether wearing Touchpoints™ on the sleep setting before bed would improve children's sleep. Using three study phases (baseline, intervention, and withdrawal), eight young children with sensory over-responsivity and sleep deficits wore Touchpoints™ on their ankles before bed during the intervention phase. Data was collected using an activity tracker to measure sleep latency, sleep duration, number of nighttime awakenings and sleep efficiency as well as parent report. Results indicated that participants did not demonstrate any significant changes in sleep efficiency, sleep duration, or number of awakenings but demonstrated a significant improvement in sleep latency. Parents also reported improvement in their child's sleep quality. Results suggest Touchpoints™ before bedtime may decrease the time it takes for children with sensory over-responsivity to fall asleep and improve parental perceptions of children's sleep quality.

The impact of nutrition on sleep in people with an intellectual disability: An integrative literature review

BACKGROUND

People with intellectual disabilities are more likely to experience sleep problems. Sleep can impact on health and well-being; therefore, evidence-based interventions are required to improve sleep in this population.

METHOD

An integrative literature review was conducted on the impact of nutrition on sleep in people with intellectual disabilities. Following screening of papers (n = 289), 14 papers met the inclusion criteria.

RESULTS

Themes related to nutrition and improved overall well-being, use of nutritional supplements, specific foods, links to health comorbidities and food fussiness.

CONCLUSION

This is the first comprehensive review completed on nutritional interventions to improve sleep in people with intellectual disabilities. Dietary patterns may be an important factor to improving the quality and quantity of sleep. However, the current literature regarding the benefit of improved nutrition on sleep in people with an intellectual disability needs to be interpreted with caution.
