Behavioral insomnia in infants and young children

Are sleep disorders associated with traumatic dental injuries in school children? A cross-sectional study

BACKGROUND

To evaluate whether the prevalence of traumatic dental injuries (TDIs) in permanent anterior teeth among school children is associated with sleep behaviours and disorders.

METHODS

A cross-sectional study was carried out with a representative sample of schoolchildren aged 8 to 10 years (n = 1402) from Florianopolis, Brazil. Clinical examinations for TDIs were performed according to the classification proposed by Andreasen. Parents/caregivers completed a questionnaire addressing sociodemographic characteristics and sleep behaviours/disorders (sleep duration, insomnia, sleep rhythmic movement, snoring, and signs of sleep apnoea). Descriptive analysis and Poisson regression were performed.

RESULTS

The prevalence of TDIs was 10.9%. Insomnia was observed in 3.0% of the children, snoring in 42.8%, sleep rhythmic movement in 27.9%, and signs of obstructive sleep apnoea in 33.6% of the schoolchildren. Most children (75.2%) slept less than eight hours a day. The prevalence of TDIs was higher among schoolchildren with an increased overjet (PR: 1.65; 95% CI: 1.15-2.35; P < 0.01), after adjusting for monthly family income, caregiver's schooling, and sleep behaviours. The prevalence of TDIs was not associated with sleep behaviours/disorders.

CONCLUSIONS

Parent-reported sleep disorders such as insomnia, sleep rhythmic movement, snoring and signs of sleep apnoea were not associated with the prevalence of TDIs in schoolchildren. © 2024 Australian Dental Association.

Identifying and developing strategies for implementation of a guided internet- and mobile-based infant sleep intervention in well-baby and community mental health clinics using group concept mapping

BACKGROUND

This study aimed to identify strategies for the implementation of a guided internet- and mobile-based intervention (IMI) for infant sleep problems ("Sleep Well, Little Sweetheart") in well-baby and community mental health clinics.

STUDY DESIGN

We used group concept mapping, a two-phased mixed methods approach, conducted as a two-day workshop in each clinic. We recruited 20 participants from four clinics and collected sorting and rating data for implementation strategies based on the Expert Recommendations for Implementing Change taxonomy and brainstorming sessions. Data were analyzed using descriptive statistics, multidimensional scaling, and hierarchical cluster analysis to create cluster maps, laddergrams, and Go-Zone graphs. Participants were presented with the results and discussed and interpreted the findings at each of the clinics in spring 2022.

RESULTS

Participants identified 10 clusters of strategies, of which Training, Embedding and Coherence, User Involvement and Participation, and Clinician Support and Implementation Counseling were rated as most important and feasible. Economy and Funding and Interactive and Interdisciplinary Collaboration were rated significantly lower on importance and feasibility compared to many of the clusters (all ps < 0.05). There was a correlation between the importance and feasibility ratings (r =.62, p =.004).

CONCLUSIONS

The use of group concept mapping made it possible to efficiently examine well-baby and community clinics' perspectives on complex issues, and to acquire specific knowledge to allow for the planning and prioritization of strategies for implementation. These results suggest areas of priority for the implementation of IMIs related to infant 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.

Comorbid insomnia and sleep apnea in children: a preliminary explorative study

Insomnia and sleep-disordered breathing (SDB) are prevalent sleep disorders. These disorders can therefore be concurrently present - comorbid insomnia and sleep apnea (COMISA). The prevalence of COMISA in the paediatric age range is unclear. As such, phenotypic constructs should help better define this comorbid condition if it exists in children and improve both diagnostic sensitivity and ultimately clinical care outcomes. We aimed to evaluate the frequency of insomnia in children and adolescents referred for evaluation of sleep symptoms suggestive of SDB in one initial (Cohort#1) and verify such findings in an independent cohort (Cohort#2) using a retrospective cross-sectional approach in patients aged 9-19 years presenting at a sleep centre to be evaluated for symptoms of SDB. Cohort #1 comprised 50 consecutive children (58% males; mean [SD] age 13.6 [3.3] years; median [interquartile range, IQR] Epworth Sleepiness Scale score 10 [6-12]) who were evaluated using validated SDB and insomnia questionnaires. Cohort#2 was extracted from electronic medical records and included 384 polysomnographically evaluated children (mean [SD] age 12.9 [3.6] years; mean [SD] body mass index z score 1.27 [0.28]; median Epworth Sleepiness Scale score 9.7 [4-17]). In Cohort #1, 56% were at high risk of SDB, 36% had insomnia alone, and 18% were at high risk of COMISA. The prevalence of COMISA in Cohort #2 was 16%, 72% had SDB alone, and 12% had insomnia alone. In both cohorts, COMISA manifested as increased propensity for sleepiness and fatigue during both waking and daytime. Thus, the presence of COMISA is frequent in the paediatric age range and accompanied by a more prominent symptomatic phenotype.

Periodic leg movements during sleep and iron status in infants with prematurity, Down syndrome and Prader-Willi syndrome

Sleep disturbances including bedtime problems and night awakenings are common during infancy. Polysomnography during the first years of life is performed mainly to rule out sleep-disordered breathing; however, sleep-related movement disorders can constitute a significant contributor to sleep disruption in this age group. Almost no studies have investigated the presence of periodic limb movements during sleep and underlying iron deficiency in infants, especially in those born preterm or with an underlying genetic syndrome. In this retrospective study we included infants 3-24 months referred for polysomnography for snoring or frequent nocturnal awakenings. All children had bloodwork (ferritin and haemoglobin) conducted within 3 months of the overnight sleep study. We studied 79 infants, including 31 (39.2%) full-term without diagnosis, 10 (12.7%) born premature, 16 (20.3%) with Down syndrome, 15 (19.0%) with Prader-Willi syndrome, and the remaining seven (8.9%) had various disorders. Compared with those with Down syndrome, Prader-Willi syndrome and full-term infants, those with prematurity showed a statistically significant elevated periodic limb movement index and lower ferritin levels than the other groups. Both ferritin (r = -0.18) and haemoglobin (r = -0.30) were negatively correlated with periodic limb movement index; however, this correlation reached statistical significance only for haemoglobin. Iron deficiency is associated with increased periodic leg movements during sleep in infants. Infants with prematurity had higher periodic limb movement index and lower ferritin levels than infants with Down syndrome, Prader-Willi syndrome or without diagnosis.

An overview of reviews for preventing and treating sleep problems in infants

AIM

Parents and professionals receive conflicting recommendations about management of infant sleep problems. The aim of this umbrella review was to provide an overview of summarised research on the prevention and treatment of sleep problems in infants (0-1 year), content of the interventions, and the conditions under which they are delivered.

METHODS

The umbrella review included five systematic reviews of 24 individual studies, mainly randomised controlled trials. Searches were conducted in PsycINFO, Cochrane, Campbell, Epistemonikos, PDQ-Evidence, IN SUM, and the Norwegian Institute of Public Health, for reviews published during 2010-2021.

RESULTS

The systematic reviews showed that behavioural interventions increased sleep in infants and parents. Interventions entailed reducing parental disturbances during sleep onset and enabling the infant to fall asleep and maintain sleep on their own. Knowledge about infant sleep and the establishment of positive bedtime routines seemed crucial for preventing and treating sleep difficulties. The interventions can be delivered in a few sessions, typically one-on-one during the postnatal period.

CONCLUSION

Behavioural interventions can be recommended and adapted to the individual family. Positive outcomes for the infant and the family depends on a close and coordinated collaboration between child health clinics, community psychologists, general physicians, and other services.
