Behavioral Sleep Problems in Children and Adolescents

Sleep Deficiency in Adolescents: The School Start Time Debate

Adolescence is commonly accepted as a challenging time for sleep, with multiple factors contributing to sleep deficiency in adolescents. These include physiologic changes with shifts in their circadian rhythm; medical sleep disorders; and social, cultural, and environmental factors. Early school start times negatively affect sleep in adolescents as well, with poorer outcomes in their overall health, wellbeing, and performance. This article highlights the different contributing factors for sleep deficiency in adolescents and the consequences of sleep deficiency. In addition, the authors discuss the impact of delayed school start times in improving adolescents' sleep and overall function.

Low Sleep Hygiene Is Associated with Less Adherence to the Mediterranean Diet in Chilean Schoolchildren from Rural Public Schools-A Cross-Sectional Study

The Mediterranean diet stands as a widely acknowledged and health-promoting dietary pattern, renowned for its notable linkage to the mitigation of noncommunicable chronic maladies. Nonetheless, the existing body of evidence concerning the potential interrelation between sleep hygiene and this dietary regimen remains circumscribed. The main objective was to determine the association between sleep hygiene and adherence to the Mediterranean diet in Chilean schoolchildren from rural public schools in southern Chile. A non-experimental study was carried out, with an analytical, cross-sectional design. A total of 265 students (56.6% women, mean age 13.5 ± 1.8) from a rural community in southern Chile were recruited. Sleep habits were evaluated using Section 6 of the Life Habits and Adolescence Questionnaire, Sleep and Rest, and adherence to the Mediterranean diet was assessed with the KIDMED Mediterranean Diet Adherence Questionnaire. The main results indicated that 52.8% of schoolchildren need to improve adherence to the Mediterranean diet and 16.6% have a low-quality Mediterranean diet. A high percentage of schoolchildren have behaviors related to poor sleep hygiene (going to bed late (46%), waking up tired and wanting to continue sleeping (63.8%), and having problems falling asleep (42.6%)). Schoolchildren who got up after 8:30 a.m., those who fell asleep after midnight, upon conducting a comparative analysis of the students based on their sleep patterns, those who woke up tired and those who had trouble falling asleep had a lower level of adherence to the Mediterranean diet compared to schoolchildren who got up earlier than 8:30 a.m., fell asleep before midnight, did not wake up tired, and those who did not find it difficult to fall asleep, respectively. In conclusion, having poor sleep patterns including difficulties in both awakening and falling asleep are associated with less adherence to the Mediterranean diet in schoolchildren from rural public schools in southern Chile. Monitoring these variables and promoting healthy lifestyle habits within the educational community are essential measures.

Sex differences in the sustained attention of elementary school children

BACKGROUND

The study investigates sex differences in sustained attention among children.

METHODS

Forty-five children (23 girls) from Grades 2-5 (mean age of 7.47 ± 0.73 years) wore an actigraph for a continuous five to seven days including school and non-school days. Sustained attention using the psychomotor vigilance test (PVT) was measured twice a day on two school days and on one non-school day.

RESULTS

No sex differences were found for sleep patterns. However, sex differences in PVT performance were documented. While boys were faster (shorter reaction time) and showed fewer lapses than girls, they showed higher number of false starts than girls, on both weekdays and weekends.

CONCLUSIONS

The findings suggest that sex differences should been taken into account in studies investigating neurobehavioral functioning, particularly, sustained attention across various age groups.

Self-reported changes in sleep patterns and behavior in children and adolescents during COVID-19

The COVID-19 pandemic and lockdowns worldwide forced children and adolescents to change and adapt their lives to an unprecedented situation. Using an online survey, we investigated whether they showed changes in sleep quality and other related factors due to this event. Between February 21st, 2021 and April 19th, 2021, a total of 2,290 Austrian children and adolescents (6-18 years) reported their sleep habits and quality of sleep as well as physical activity, daylight exposure and usage of media devices during and, retrospectively, before the pandemic. Results showed an overall delay of sleep and wake times. Almost twice as many respondents reported having sleeping problems during the pandemic as compared to before, with insomnia, nightmares and daytime sleepiness being the most prevalent problems. Furthermore, sleeping problems and poor quality of sleep correlated positively with COVID-19 related anxiety. Lastly, results showed a change from regular to irregular bedtimes during COVID-19, higher napping rates, a strong to very strong decrease in physical activity and daylight exposure, as well as a high to very high increase in media consumption. We conclude that the increase in sleeping problems in children and adolescent during COVID-19 is concerning. Thus, health promoting measures and programs should be implemented and enforced.

Cognitive Behavioral Therapy for Insomnia in School-Aged Children and Adolescents

One of the most prevalent sleep disorders in children and adolescents is "insomnia," which can be briefly described as problems with initiating and/or maintaining sleep with associated daytime consequences. These are typical insomnia symptoms, and when experienced for long enough and when they interfere with an important area of the young person's life (eg, schooling), then a diagnosis of an insomnia disorder may be warranted. The authors strongly urge the scientific community to conduct further controlled trials, including dismantling trials that evaluate the relative effectiveness of individual cognitive behavioral therapy for insomnia components.

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.

Behavioral problems in the children of women who are victims of intimate partner violence

OBJECTIVE

The purpose of this study was to investigate the association between the maternal experience of intimate partner violence (IPV) and children's behavioral problems.

SAMPLE

The secondary data of the National Survey on Women's Health and Life Experience, which included 980 Cambodian children aged 6-12 years whose mothers responded to questions, were analyzed.

MEASUREMENTS

IPV was measured as any experience of physical or sexual violence against a woman by her husband. The children's behavioral problems were indicated by nightmares, bed-wetting, timidity, and aggressive behavior as reported by their mothers.

RESULTS

The children of the women who had experienced sexual violence had a higher prevalence of nightmares (adjusted OR (aOR) = 2.22, 95% CI: 1.421-3.470), bed-wetting (aOR = 2.15, 95% CI: 1.398-3.308), and timidity (aOR = 1.80, 95% CI 1.075-3.019) than those without reported IPV. The children of mothers who had experienced physical violence had a higher rate of aggression (OR  =  2.19, 95% CI: 1.321-3.630).

CONCLUSION

The Cambodian children exposed to IPV against their mothers experienced more behavioral problems. This study presents evidence to support changes in current policy to prevent violence and alleviate behavioral problems.

Sleep Deficiency and Pediatric Chronic Pain

Sleep deficiency in children is a public health concern, and it is highly comorbid in pediatric chronic pain conditions. Children may be particularly vulnerable to the deleterious effects of sleep deficiency, because comorbid sleep deficiency in chronic pain may further exacerbate already existent symptoms of pain, anxiety, depressions, daytime function, and increase health care use. Sleep deficiency is modifiable and integrating human-centered approaches into the development of sleep interventions is a pragmatic approach to partner with parents and children to provide them with the knowledge, motivation, and skills for setting and achieving goals, adapting to setbacks, and problem solving.

Hair Cortisol Concentration as a Biomarker of Sleep Quality and Related Disorders

Cortisol is the end product of the hypothalamic-pituitary-adrenal (HPA) axis, and its production is increased mainly in stressful situations or in chronic disorders accompanied by stress enhancement. Altered cortisol concentrations have been reported in a number of neuropsychiatric diseases and sleep disorders. Cortisol concentrations have been measured using several methods, and in several matrixes, such as blood, saliva, and urine. However, lately, hair cortisol, for several reasons, has emerged as a promising biomarker of long-term retrospective HPA activation. Several experimental approaches for cortisol measurement with the corresponding concentration reference ranges and a summary of findings from scientific literature on this field are presented. There is evidence of a close relationship between HPA functional alteration and the development of neuropsychiatric disorders. Sleep disorders are the most common manifestation in several neuropsychiatric conditions, and have also been associated to cortisol alterations in both adults and children. Many studies indicate that hair cortisol constitutes a valuable tool for further contributing to existing data on salivary, plasma, or urinary cortisol concentrations in patients with sleep disorders.

Evaluation of Facilitators and Barriers to Implementing Evidence-Based Practice in the Health Services: A Systematic Review

BACKGROUND

Evidence-based practice (EBP) is an ambition for health service administrators. We aimed to systematically review the major relevant articles in case of barriers and facilitators to implementing evidence-based practice in health services.

MATERIALS AND METHODS

The type of study was a systematic review. We searched the libraries and online sources such as PubMed, MEDLINE, Wiley, EMBASE, ISI Web of Knowledge, Scopus, Science Direct, Cochrane Library, and Google scholar. We used keywords included "Evidence-Based Practice", "Evidence-Based Management", "Healthcare", "Care Management, Evidence-Based Healthcare Management", "Health Care", Health", "Barrier", "Facilitator", policy and "Evidence-Based Healthcare".

RESULTS

In total, 12 studies were included. Several barriers and facilitators were recognized through the included papers, the factors such as organization support and a helpful education system improved skills, knowledge, and confidence to EBP. The outcomes of studies were identified as the employ of the internet as a highest-rated skill for increasing EBP quality.

CONCLUSION

Generally, the results showed health service administrators should first identify barriers of EBP then transferred them to facilitators to the implementation of proper and efficient EBP.

Twenty-four-hour motor activity and body temperature patterns suggest altered central circadian timekeeping in Smith-Magenis syndrome, a neurodevelopmental disorder

Smith-Magenis syndrome (SMS) is a contiguous gene syndrome linked to interstitial microdeletion, or mutation of RAI1, within chromosome 17p11.2. Key behavioral features of SMS include intellectual disability, sleep-disturbances, maladaptive, aggressive and self-injurious behaviors, hyperactivity, and sudden changes in mood. A distinguishing feature of this syndrome is an inverted pattern of melatonin characterized by elevated daytime and low nighttime melatonin levels. As the central circadian clock controls the 24-hr rhythm of melatonin, we hypothesized that the clock itself may contribute to the disrupted pattern of melatonin and sleep. In this report, 24-hr patterns of body temperature, a surrogate marker of clock-timing, and continuous wrist activity were collected to examine the links between body temperature, sleep behavior, and the circadian clock. In addition, age-dependent changes in sleep behavior were explored. Actigraphy-estimated sleep time for SMS was 1 hr less than expected across all ages studied. The timing of the 24-hr body temperature (Tb-24) rhythm was phase advanced, but not inverted. Compared to sibling (SIB) controls, the SMS group had less total night sleep, lower sleep efficiency, earlier sleep onset, earlier final awake times, increased waking after sleep onset (WASO), and increased daytime nap duration. The timing of wake onset varied with age, providing evidence of ongoing developmental sleep changes from childhood through adolescence. Clarification of the circadian and developmental factors that contribute to the disrupted and variable sleep patterns in this syndrome will be helpful in identifying more effective individualized treatments.

What does sleep hygiene have to offer children's sleep problems?

Sleep hygiene practices have been described extensively in the literature. There is considerably less clarity about relationships between particular elements of sleep hygiene and particular sleep outcomes, and which intervention approaches using sleep hygiene principles are effective. In this review, we describe themes extracted from a systematic review of the sleep hygiene literature. We systematically searched Psycinfo, CINAHL, Cochrane, Ovid Medline, Embase, and Web of Science Search Engines up to August, 2017. We included all studies that associated sleep hygiene (behaviors adjacent to bedtime and during the night) with sleep duration and/or sleep onset latency and/or night waking or that used sleep-hygiene based interventions to improve sleep duration and/or sleep onset latency and/or night waking (n = 44). We organized our findings into themes by age group, sleep hygiene factors, and interventions. We provide evidence-based recommendations about areas of sleep hygiene that have significant empirical support and those that require urgent attention.

Cognitive Behavioral Therapy for Insomnia (CBT-i) in School-Aged Children and Adolescents

Insomnia is one of the most prevalent sleep disorders in school-aged children and adolescents. Although cognitive behavioral therapy for insomnia (CBT-i) is the first-line treatment for adults, and existing studies show promising effects also for children and adolescents, the number of randomized controlled trials in younger age groups is rather small. CBT-i techniques for school-aged children and adolescents include bedtime shifts (including sleep restriction), stimulus control, thought challenging, psychoeducation, and relaxation techniques. The integration of parents, especially in school-aged children with insomnia, is highly recommended. More research is needed to investigate specific characteristics and models of child and adolescent insomnia.

"How do you sleep?" sleep in self-figure drawings of young adolescents in residential care facilities-An exploratory study

OBJECTIVE

Children and adolescents who are referred to residential care facilities (RCFs) have a history of neglect, abuse, or other familial or environmental deficiencies, all of which may contribute to a higher risk of sleep problems. The purpose of this study was to explore sleep patterns of young adolescents living in RCFs and to examine whether these patterns are reflected in their self-figure drawings and accompanying narrative descriptions.

METHOD

The study compared quantitative subjective (self-report) and objective (actigraphy) measurements of sleep patterns in young adolescents living in RCFs (n = 26) and at home (n = 33), and explored a quantitative indicators analysis of "self-figure drawing while sleeping" and qualitative analysis of accompanying narrative descriptions.

RESULTS

Adolescents in RCFs went to bed at least an hour earlier and woke up at least half an hour earlier than their home-residing counterparts (p < 0.001). Based on actigraphy, their sleep duration and sleep latency were longer (p < 0.01). They frequently drew themselves in a closed boundary, viewed from above, and used monochromatic colors. Analysis of the narratives revealed themes of exclusion, which reflect the need to exclude oneself from threatening and anxiety-provoking experiences.

CONCLUSIONS

Adolescents in RCFs take longer to fall asleep; however, imposed early sleep schedules in RCFs enable good sleep hygiene practices that allow for longer sleep duration compared with home-residing peers and can prevent additional sleep problems. The need for protection and a sense of security emerged from the drawings and the accompanying narratives.

Sleep: An underemphasized aspect of health and development in neurorehabilitation

Sleep deficiency has unique causes and implications for children with neonatal brain injury; contributing to the development or exacerbation of neurodevelopmental impairments and yet it is an underemphasized aspect of health and development. There is very little research evidence to guide the management of sleep disorders in children with cerebral palsy, a common neurodevelopmental disability of childhood. This paper is a comprehensive review and analysis of the literature regarding what is known about sleep quantity and quality in children with cerebral palsy. The specific implications for children with cerebral palsy are explored including the adverse effects of sleep deficiency on general child development, physical health and growth, and mental functioning. The consequences for the family are also discussed. Finally, the assessment and management of sleep problems are summarized to provide guidance to clinicians who work in neurodevelopmental medicine.

A preliminary study of movement intensity during a Go/No-Go task and its association with ADHD outcomes and symptom severity

OBJECTIVE

At present, there are no well-validated biomarkers for attention-deficit/hyperactivity disorder (ADHD). The present study used an infrared motion tracking system to monitor and record the movement intensity of children and to determine its diagnostic precision for ADHD and its possible associations with ratings of ADHD symptom severity.

METHODS

A Microsoft motion sensing camera recorded the movement of children during a modified Go/No-Go Task. Movement intensity measures extracted from these data included a composite measure of total movement intensity (TMI measure) and a movement intensity distribution (MID measure) measure across 15 frequency bands (FB measures). In phase 1 of the study, 30 children diagnosed with ADHD or at subthreshold for ADHD and 30 matched healthy controls were compared to determine if measures of movement intensity successfully distinguished children with ADHD from healthy control children. In phase 2, associations between measures of movement intensity and clinician-rated ADHD symptom severity (Clinical Global Impression Scale [CGI] and the ADHD-Rating Scale IV [ADHD-RS]) were examined in a subset of children with ADHD (n = 14) from the phase I sample.

RESULTS

Both measures of movement intensity were able to distinguish children with ADHD from healthy controls. However, only the measures linked to the 15 pre-determined 1 Hz frequency bands were significantly correlated with both the CGI scores and ADHD-RS total scores.

CONCLUSIONS

Preliminary findings suggest that measures of movement intensity, particularly measures linked to the 10-11 and 12-13 Hz frequency bands, have the potential to become valid biomarkers for ADHD.

Supporting sleep in early care and education: an assessment of observed sleep times using a sleep practices optimality index

AIM

The aim was to investigate whether the sleep practices in early childhood education (ECE) settings align with current evidence on optimal practice to support sleep.

BACKGROUND

Internationally, scheduled sleep times are a common feature of daily schedules in ECE settings, yet little is known about the degree to which care practices in these settings align with the evidence regarding appropriate support of sleep.

METHODS

Observations were conducted in 130 Australian ECE rooms attended by preschool children (Mean=4.9years). Of these rooms, 118 had daily scheduled sleep times. Observed practices were scored against an optimality index, the Sleep Environment and Practices Optimality Score, developed with reference to current evidence regarding sleep scheduling, routines, environmental stimuli, and emotional climate. Cluster analysis was applied to identify patterns and prevalence of care practices in the sleep time.

RESULTS

Three sleep practices types were identified. Supportive rooms (36%) engaged in practices that maintained regular schedules, promoted routine, reduced environmental stimulation, and maintained positive emotional climate. The majority of ECE rooms (64%), although offering opportunity for sleep, did not engage in supportive practices: Ambivalent rooms (45%) were emotionally positive but did not support sleep; Unsupportive rooms (19%) were both emotionally negative and unsupportive in their practices.

CONCLUSIONS

Although ECE rooms schedule sleep time, many do not adopt practices that are supportive of sleep. Our results underscore the need for education about sleep supporting practice and research to ascertain the impact of sleep practices in ECE settings on children's sleep health and broader well-being.

Association between delayed bedtime and sleep-related problems among community-dwelling 2-year-old children in Japan

Background

Although delayed sleep timing causes many socio-psycho-biological problems such as sleep loss, excessive daytime sleepiness, obesity, and impaired daytime neurocognitive performance in adults, there are insufficient data showing the clinical significance of a ‘night owl lifestyle’ in early life. This study examined the association between habitual delayed bedtime and sleep-related problems among community-dwelling 2-year-old children in Japan.

Methods

Parents/caregivers of 708 community-dwelling 2-year-old children in Nishitokyo City, Tokyo, participated in the study. The participants answered a questionnaire to evaluate their child’s sleep habits and sleep-related problems for the past 1 month.

Results

Of the 425 children for whom complete data were collected, 90 (21.2%) went to bed at 22:00 or later. Children with delayed bedtime showed significantly more irregular bedtime, delayed wake time, shorter total sleep time, and difficulty in initiating and terminating sleep. Although this relationship indicated the presence of sleep debt in children with delayed bedtime, sleep onset latency did not differ between children with earlier bedtime and those with delayed bedtime. Rather, delayed bedtime was significantly associated with bedtime resistance and problems in the morning even when adjusting for nighttime and daytime sleep time.

Conclusions

Even in 2-year-old children, delayed bedtime was associated with various sleep-related problems. The causal factors may include diminished homeostatic sleep drive due to prolonged daytime nap as well as diurnal preference (morning or night type) regulated by the biological clock.

Barriers and facilitators of evidence-based practice in pediatric behavioral sleep care: qualitative analysis of the perspectives of health professionals

Behavioral sleep problems are highly prevalent among young and school-aged children. Despite strong evidence for effective interventions, few children receive evidence-based care. In this study, 124 Canadian health professionals answered open-ended questions regarding barriers and facilitators of their provision of evidence-based behavioral sleep-related care, and responses were analyzed for content. Responses represented issues at an individual practice level, as well as broader systemic issues. The most frequently reported barrier and facilitator related to knowledge, training, and education. Other barriers included lack of time and institutional support, and facilitators included supportive sleep attitudes and beliefs. This study may inform the design of education programs for health professionals, and provides support for broader systems-level initiatives targeted at increasing evidence-based practice.

Association Between Internet Use and Sleep Problems in Adolescents

INTRODUCTION

Sleep problems are commonly encountered in adolescents. It has been shown that electronic media have a negative influence on the sleep quality and daytime functioning in adolescents. This study aims to investigate the association between internet use and sleep problems in adolescents.

METHOD

A total of 1212 adolescents were recruited to the study. Self-report study questionnaire included two main parts: Young's Internet Addiction Scale (IAS) and a semi-structured inquiry on sleep habits/problems.

RESULTS

Of the study sample, 16% (n=198) reported their sleep quality as bad or very bad. One-fourth of the sample reported using internet everyday and 27% of them reported spending more than one hour when online. The mean IAS total score was 35.56±13.87. Adolescents with a higher IAS score reported getting to bed later in the night, needing more time to fall asleep and having an increased number of awakenings in the night than the adolescents with lower IAS score (p=.001). They were also found to have higher frequencies of several sleep problems including difficulty in initiating and sustaining sleep, difficulty in waking up and feelings of sleepiness in day. In addition, sleep quality of them was worse when compared to the adolescents with a lower IAS score (p=.001).

CONCLUSION

Problematic sleep habits and sleep problems were found to be more frequent in adolescents with a higher IAS total score. Health care providers must be aware of the possible negative impact of excessive and uncontrolled internet use on adolescents' sleep habits.

Clinical Implications of Impaired Sleep

Despite its pervasiveness in primary care, deficient sleep often is underappreciated as a cue to other health risks. Accordingly, this review discusses contemporary evidence-based perspectives on impaired sleep and its associations with other lifestyle medicine concerns, including obesity, cardiovascular conditions, psychological problems, and health-compromising habits. The potential clinical benefits of promoting sleep health also will be considered.

Preparing psychologists in academic health centers for the rapidly changing health care environment

The Association of Psychologists in Academic Health Centers (APAHC) convened its 5th National APAHC Conference in Boston March 3-5 2011. The conference and its theme, "Preparing Psychologists for a Rapidly Changing Health Care Environment," brought psychologists from academic health centers together to examine how psychology can adapt to and help lead health care efforts in the face of health care reform. This paper reports on the conference and introduces the special issue of JCPMS that is dedicated to the conference. The conference theme is framed in the historical context of the four national conferences that preceded it. In examining the focus and topics of the preceding conferences, recurrent themes are identified and progress in certain areas is highlighted.
