Abstract
STUDY OBJECTIVES We aimed to examine the association between self-rated and clinician-rated sleep disturbances and C-reactive protein (CRP), an objective marker of inflammation, in pediatric depression. METHODS Two hundred fifty-six children and adolescents (15.2 ± 1.6 y, 72.3% female) with moderate to severe symptoms of depression participated in the study. Sleep disturbances were assessed by self-reports (Insomnia Severity Index) and clinician ratings (Kiddie-Schedule for Affective Disorder and Schizophrenia), inflammation by plasma CRP levels. RESULTS Higher levels of CRP correlated positively with clinician-rated middle insomnia and hypersomnia. After adjusting for control variables (body mass index, tobacco, alcohol, stress, age, sex, antidepressants, sleep medication, depression severity), regression models confirmed the significant association of clinician-rated hypersomnia and middle insomnia symptoms with elevated CRP levels. In the adjusted regression models, other clinician-rated manifestations of sleep disturbance (eg, initial insomnia) and insomnia self-ratings were not significantly associated with CRP. Body mass index correlated positively with CRP, but body mass index had no mediating effect on the associations between sleep disturbances and CRP. We did not find an association between depression severity, assessed by the Children's Depression Rating Scale-Revised, and CRP. CONCLUSIONS Results of the present study indicate a significant association of hypersomnia and middle insomnia symptoms with CRP in pediatric depression, not linked to alterations in the body mass index.

Abstract
This White Paper addresses the current gaps in knowledge, as well as opportunities for future studies in pediatric sleep. The Sleep Research Society's Pipeline Development Committee assembled a panel of experts tasked to provide information to those interested in learning more about the field of pediatric sleep, including trainees. We cover the scope of pediatric sleep, including epidemiological studies and the development of sleep and circadian rhythms in early childhood and adolescence. Additionally, we discuss current knowledge of insufficient sleep and circadian disruption, addressing the neuropsychological impact (affective functioning) and cardiometabolic consequences. A significant portion of this White Paper explores pediatric sleep disorders (including circadian rhythm disorders, insomnia, restless leg and periodic limb movement disorder, narcolepsy, and sleep apnea), as well as sleep and neurodevelopment disorders (e.g. autism and attention deficit hyperactivity disorder). Finally, we end with a discussion on sleep and public health policy. Although we have made strides in our knowledge of pediatric sleep, it is imperative that we address the gaps to the best of our knowledge and the pitfalls of our methodologies. For example, more work needs to be done to assess pediatric sleep using objective methodologies (i.e. actigraphy and polysomnography), to explore sleep disparities, to improve accessibility to evidence-based treatments, and to identify potential risks and protective markers of disorders in children. Expanding trainee exposure to pediatric sleep and elucidating future directions for study will significantly improve the future of the field.

Abstract
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.

Abstract
Objectives Child and adolescent sleep is an important factor for brain and physical development. Therefore, it is necessary to investigate the prevalence of sleep disorders and nonorganic sleep disorders in children and adolescents and determine the type of utilization of medical institutions. This study analyzed the prevalence and type of medical institutions in Korean children and adolescents with sleep disorders and nonorganic sleep disorders. Methods This study used data recorded in the Health Insurance Review and Assessment-National Patient Sample (HIRA-NPS) database from 2010 to 2017. Details of medical institution type and patient’s sex, age, and treatment type were extracted for patients younger than 20 years with sleep disorders and nonorganic sleep disorders. Results Among 2,536,478 patients under age 20, we identified 3,772 patients with sleep disorders or nonorganic sleep disorders. From 2010 to 2017, the prevalence of sleep disorders in children and adolescents was 0.07% to 0.09%. The utilization rate of Korean medical institutions was 30.47%. The prevalence of nonorganic sleep disorders and the utilization rate of Korean medical institutions were 0.06% to 0.08% and 45.99%, respectively. Conclusion The prevalence of sleep disorders and nonorganic sleep disorders in the under-20 population was 0.14% to 0.16%. More than 70% of patients with nonorganic sleep disorder who were younger than 9 years used Korean medical institutions.

Abstract
Intellectual disability is the impairment of cognitive, linguistic, motor and social skills that occurs in the pediatric age and is also described by the term "mental retardation". Intellectual disability occurs in 3-28 % of the general population due to a genetic cause, including chromosome aberrations. Among people with intellectual disabilities, the cause of the disability was identified as a single gene disorder in up to 12 %, multifactorial disorders in up to 4 %, and genetic disorders in up to 8.5 %. Children affected by a malformation syndrome associated with mental retardation or intellectual disability represent a care challenge for the pediatrician. A multidisciplinary team is essential to manage the patient, thereby controlling the complications of the syndrome and promoting the correct psychophysical development. This requires continuous follow-up of these children by the pediatrician, which is essential for both the clinical management of the syndrome and facilitating the social integration of these children.

Abstract
IMPORTANCE Cerebral palsy (CP) is the most common childhood physical disability. Early intervention for children younger than 2 years with or at risk of CP is critical. Now that an evidence-based guideline for early accurate diagnosis of CP exists, there is a need to summarize effective, CP-specific early intervention and conduct new trials that harness plasticity to improve function and increase participation. Our recommendations apply primarily to children at high risk of CP or with a diagnosis of CP, aged 0 to 2 years. OBJECTIVE To systematically review the best available evidence about CP-specific early interventions across 9 domains promoting motor function, cognitive skills, communication, eating and drinking, vision, sleep, managing muscle tone, musculoskeletal health, and parental support. EVIDENCE REVIEW The literature was systematically searched for the best available evidence for intervention for children aged 0 to 2 years at high risk of or with CP. Databases included CINAHL, Cochrane, Embase, MEDLINE, PsycInfo, and Scopus. Systematic reviews and randomized clinical trials (RCTs) were appraised by A Measurement Tool to Assess Systematic Reviews (AMSTAR) or Cochrane Risk of Bias tools. Recommendations were formed using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) framework and reported according to the Appraisal of Guidelines, Research, and Evaluation (AGREE) II instrument. FINDINGS Sixteen systematic reviews and 27 RCTs met inclusion criteria. Quality varied. Three best-practice principles were supported for the 9 domains: (1) immediate referral for intervention after a diagnosis of high risk of CP, (2) building parental capacity for attachment, and (3) parental goal-setting at the commencement of intervention. Twenty-eight recommendations (24 for and 4 against) specific to the 9 domains are supported with key evidence: motor function (4 recommendations), cognitive skills (2), communication (7), eating and drinking (2), vision (4), sleep (7), tone (1), musculoskeletal health (2), and parent support (5). CONCLUSIONS AND RELEVANCE When a child meets the criteria of high risk of CP, intervention should start as soon as possible. Parents want an early diagnosis and treatment and support implementation as soon as possible. Early intervention builds on a critical developmental time for plasticity of developing systems. Referrals for intervention across the 9 domains should be specific as per recommendations in this guideline.

Abstract
Twin studies have consistently found that genetic factors explain a substantial proportion of the variance for insomnia. However, studies vary widely in their heritability estimates. Therefore, this meta-analysis aimed to: 1) Estimate the mean heritability of insomnia; 2) Assess heterogeneity among twin studies of insomnia; and 3) Search and analyse characteristics of the studies (moderator variables) that may explain heterogeneity among estimates. For this purpose, separate meta-analyses were carried out for MZ and DZ correlations and for heritability estimates by assuming random-effects models. Thirteen independent samples were included in this meta-analysis. The heterogeneity index for heritability estimates was significant in both best fitting models (I2 = 98.77, P < .0001) and full models (I2 = 97.80, P < .0001). MZ correlations were higher (0.37; 95%CI: 0.31,.43) than DZ correlations (0.15; 95%CI: 0.12,.18). A mean heritability of 0.39 (95%CI: 0.32,.44) was found for insomnia. These results highlight the role of genetic factors in explaining differences among the population on insomnia and Emphasize heterogeneity among studies. Further research is needed to identify variables that could explain this heterogeneity.

Abstract
BACKGROUND Obstructive sleep apnoea (OSA) is characterised by partial or complete upper airway obstruction during sleep. Approximately 1% to 4% of children are affected by OSA, with adenotonsillar hypertrophy being the most common underlying risk factor. Surgical removal of enlarged adenoids or tonsils is the currently recommended first-line treatment for OSA due to adenotonsillar hypertrophy. Given the perioperative risk and an estimated recurrence rate of up to 20% following surgery, there has recently been an increased interest in less invasive alternatives to adenotonsillectomy. As the enlarged adenoids and tonsils consist of hypertrophied lymphoid tissue, anti-inflammatory drugs have been proposed as a potential non-surgical treatment option in children with OSA. OBJECTIVES To assess the efficacy and safety of anti-inflammatory drugs for the treatment of OSA in children. SEARCH METHODS We identified trials from searches of the Cochrane Airways Group Specialised Register, CENTRAL and MEDLINE (1950 to 2019). For identification of ongoing clinical trials, we searched ClinicalTrials.gov and the World Health Organization (WHO) trials portal. SELECTION CRITERIA Randomised controlled trials (RCTs) comparing anti-inflammatory drugs against placebo in children between one and 16 years with objectively diagnosed OSA (apnoea/hypopnoea index (AHI) ≥ 1 per hour). DATA COLLECTION AND ANALYSIS Two authors independently performed screening, data extraction, and quality assessment. We separately pooled results for the comparisons 'intranasal steroids' and 'montelukast' against placebo using random-effects models. The primary outcomes for this review were AHI and serious adverse events. Secondary outcomes included the respiratory disturbance index, desaturation index, respiratory arousal index, nadir arterial oxygen saturation, mean arterial oxygen saturation, avoidance of surgical treatment for OSA, clinical symptom score, tonsillar size, and adverse events. MAIN RESULTS We included five trials with a total of 240 children aged one to 18 years with mild to moderate OSA (AHI 1 to 30 per hour). All trials were performed in specialised sleep medicine clinics at tertiary care centres. Follow-up time ranged from six weeks to four months. Three RCTs (n = 137) compared intranasal steroids against placebo; two RCTs compared oral montelukast against placebo (n = 103). We excluded one trial from the meta-analysis since the patients were not analysed as randomised. We also had concerns about selective reporting in another trial. We are uncertain about the difference in AHI (MD -3.18, 95% CI -8.70 to 2.35) between children receiving intranasal corticosteroids compared to placebo (2 studies, 75 participants; low-certainty evidence). In contrast, children receiving oral montelukast had a lower AHI (MD -3.41, 95% CI -5.36 to -1.45) compared to those in the placebo group (2 studies, 103 participants; moderate-certainty evidence). We are uncertain whether the secondary outcomes are different between children receiving intranasal corticosteroids compared to placebo: desaturation index (MD -2.12, 95% CI -4.27 to 0.04; 2 studies, 75 participants; moderate-certainty evidence), respiratory arousal index (MD -0.71, 95% CI -6.25 to 4.83; 2 studies, 75 participants; low-certainty evidence), and nadir oxygen saturation (MD 0.59%, 95% CI -1.09 to 2.27; 2 studies, 75 participants; moderate-certainty evidence). Children receiving oral montelukast had a lower respiratory arousal index (MD -2.89, 95% CI -4.68 to -1.10; 2 studies, 103 participants; moderate-certainty evidence) and nadir of oxygen saturation (MD 4.07, 95% CI 2.27 to 5.88; 2 studies, 103 participants; high-certainty evidence) compared to those in the placebo group. We are uncertain, however, about the difference in desaturation index (MD -2.50, 95% CI -5.53 to 0.54; 2 studies, 103 participants; low-certainty evidence) between the montelukast and placebo group. Adverse events were assessed and reported in all trials and were rare, of minor nature (e.g. nasal bleeding), and evenly distributed between study groups. No study examined the avoidance of surgical treatment for OSA as an outcome. AUTHORS' CONCLUSIONS There is insufficient evidence for the efficacy of intranasal corticosteroids for the treatment of OSA in children; they may have short-term beneficial effects on the desaturation index and oxygen saturation in children with mild to moderate OSA but the certainty of the benefit on the primary outcome AHI, as well as the respiratory arousal index, was low due to imprecision of the estimates and heterogeneity between studies. Montelukast has short-term beneficial treatment effects for OSA in otherwise healthy, non-obese, surgically untreated children (moderate certainty for primary outcome and moderate and high certainty, respectively, for two secondary outcomes) by significantly reducing the number of apnoeas, hypopnoeas, and respiratory arousals during sleep. In addition, montelukast was well tolerated in the children studied. The clinical relevance of the observed treatment effects remains unclear, however, because minimal clinically important differences are not yet established for polysomnography-based outcomes in children. Long-term efficacy and safety data on the use of anti-inflammatory medications for the treatment of OSA in childhood are still not available. In addition, patient-centred outcomes like concentration ability, vigilance, or school performance have not been investigated yet. There are currently no RCTs on the use of other kinds of anti-inflammatory medications for the treatment of OSA in children. Future RCTs should investigate sustainability of treatment effects, avoidance of surgical treatment for OSA, and long-term safety of anti-inflammatory medications for the treatment of OSA in children and include patient-centred outcomes.

Abstract
BACKGROUND Sleep terrors are common, frightening, but fortunately benign events. Familiarity with this condition is important so that an accurate diagnosis can be made. OBJECTIVE To familiarize physicians with the clinical manifestations, diagnosis, and management of children with sleep terrors. METHODS A PubMed search was completed in Clinical Queries using the key terms "sleep terrors" OR "night terrors". The search strategy included meta-analyses, randomized controlled trials, clinical trials, observational studies, and reviews. Only papers published in the English literature were included in this review. The information retrieved from the above search was used in the compilation of the present article. RESULTS It is estimated that sleep terrors occur in 1 to 6.5% of children 1 to 12 years of age. Sleep terrors typically occur in children between 4 and 12 years of age, with a peak between 5 and 7 years of age. The exact etiology is not known. Developmental, environmental, organic, psychological, and genetic factors have been identified as a potential cause of sleep terrors. Sleep terrors tend to occur within the first three hours of the major sleep episode, during arousal from stage three or four non-rapid eye movement (NREM) sleep. In a typical attack, the child awakens abruptly from sleep, sits upright in bed or jumps out of bed, screams in terror and intense fear, is panicky, and has a frightened expression. The child is confused and incoherent: verbalization is generally present but disorganized. Autonomic hyperactivity is manifested by tachycardia, tachypnea, diaphoresis, flushed face, dilated pupils, agitation, tremulousness, and increased muscle tone. The child is difficult to arouse and console and may express feelings of anxiety or doom. In the majority of cases, the patient does not awaken fully and settles back to quiet and deep sleep. There is retrograde amnesia for the attack the following morning. Attempts to interrupt a sleep terror episode should be avoided. As sleep deprivation can predispose to sleep terrors, it is important that the child has good sleep hygiene and an appropriate sleeping environment. Medical intervention is usually not necessary, but clonazepam may be considered on a short-term basis at bedtime if sleep terrors are frequent and severe or are associated with functional impairment, such as fatigue, daytime sleepiness, and distress. Anticipatory awakening, performed approximately half an hour before the child is most likely to experience a sleep terror episode, is often effective for the treatment of frequently occurring sleep terrors. CONCLUSION Most children outgrow the disorder by late adolescence. In the majority of cases, there is no specific treatment other than reassurance and parental education. Underlying conditions, however, should be treated if possible and precipitating factors should be avoided.

Abstract
BACKGROUND Traditional medicine is widely used for patients with primary insomnia, but the studies showed inconsistent results. We performed a meta-analysis of randomized controlled trials (RCTs) to evaluate the effectiveness of Chinese herbal medicine (CHM) versus placebo for primary insomnia patients. METHODS The electronic databases including PubMed, EmBase, Cochrane library, and China National Knowledge Infrastructure were searched to identify the RCTs published from inception till July 2018. The summary weighted mean difference (WMD) with its 95% confidence interval (CI) for Pittsburgh sleep quality index (PSQI), sleep onset latency, total sleep duration, Athens insomnia scale (AIS), and sleep efficiency were calculated using random-effects model. RESULTS Fifteen RCTs comprising 1500 patients were finally included in the meta-analysis. Overall, patients who received CHM had lower levels of PSQI (WMD: -2.36; 95% CI: -4.02 to -0.70; P = .005), sleep onset latency (WMD: -11.54; 95% CI: -20.55 to -2.54; P = .012), and AIS (WMD: -0.59; 95% CI: -0.97 to -0.22; P = .002) as compared with placebo. Moreover, the summary WMDs of CHM versus placebo were associated with higher total sleep duration (WMD: 0.79; 95% CI: 0.56-1.02; P < .001), and sleep efficiency (WMD: 9.72; 95% CI: 6.49-12.96; P < .001). The treatment effect on PSQI might be affected by publication year, sample size, mean age, percentage male, diagnostic tool, duration of insomnia, treatment duration, and study quality. CONCLUSION The findings of this meta-analysis indicated that CHM could significantly improve the symptoms of insomnia than placebo for patients with primary insomnia.

Abstract
OBJECTIVE To determine which pediatric populations, if any, benefit from exogenous melatonin supplementation. METHODS PubMed was utilized for the purposes of this systematic review. The studies selected evaluated melatonin use in pediatric special populations and included randomized controlled trials, crossover studies, and meta-analyses. Each study's objectives, measures of outcomes, and dosing strategies of melatonin were reviewed along with the results and author's conclusions. RESULTS Our analysis of the available data offers mixed results and recommendations with regard to the decision of whether to add supplementation of melatonin. CONCLUSION With further regulation of melatonin supplements, it may be plausible to hold larger, multicenter trials and come to a firm recommendation in the future. At this time, we believe that the benefit of exogenous melatonin supplementation outweighs the risks of adverse events and therefore would recommend its use in aiding patients in improving their sleep. Exogenous supplementation with melatonin should be used at the physician's and patient's discretion.

Abstract
OBJECTIVES This study proposed a version of the Children's Sleep Habits Questionnaire for infants under 12 months (CSHQ-I). METHODS The sample was comprised of 299 infants, aged between 2 weeks and 12 months. RESULTS Exploratory factor analysis revealed four subscales: Bedtime Resistance, Sleep Anxiety, Positive Sleep Habits, and Daytime Sleepiness. The CSHQ-I total scale presented good test-retest reliability and internal consistency. The CSHQ-I also showed good concurrent validity, with significant associations found between the CSHQ-I total scale and subscales and a measure of infant sleep-wake behaviors. CONCLUSIONS The present study suggested the CSHQ-I as a reliable instrument to assess sleep problems in infants during the first year of life.

Abstract
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.

Abstract
This study aimed to explore the pathological change to hippocampal neurons and the expression of growth associated protein 43 in 21-day-old young rats following chronic intermittent hypoxia. Hematoxylin-eosin staining results showed varying degrees of degeneration and necrosis in hippocampal neurons depending on the modeling time. Immunohistochemistry revealed that growth associated protein 43 expression in young rats following chronic intermittent hypoxia decreased, but that levels were still higher than those of normal rats at each time point, especially 4 weeks after modeling. During 1–5 weeks after modeling, a slow growth in rat weight was observed. Experimental findings indicate that chronic intermittent hypoxia may induce growth dysfunction and necrosis of hippocampal neurons, as well as increase the expression of growth associated protein 43 in young rats.

Abstract
STUDY OBJECTIVES Obstructive sleep symptoms are common in children with craniofacial malformations (CFM). However objective data about obstructive sleep apnea (OSA) is still limited. The aims of this study were to investigate the frequency of OSA in symptomatic children with CFM and to determine improvement in severity of OSA after treatment. METHODS Symptomatic children with CFM referred for a diagnostic polysomnogram (PSG) were identified. Obstructive sleep apnea was defined as an apnea/hypopnea index (AHI) ≥ 1, with moderate/severe OSA as an AHI ≥ 5. RESULTS Overall, 151 symptomatic children were identified; 87% were diagnosed with OSA, of whom 24% had moderate-to-severe OSA. Children with syndromic CFM, compared to non-syndromic CFM, were more likely to have an AHI ≥ 5 (syndromic 33% vs. non-syndromic 15%, p = 0.02). Of the 131 children with OSA, 64 were treated and 32 returned for a posttreatment PSG, with 22 treated with either positive airway pressure (PAP) or adenotonsillectomy (AT). Children treated with PAP demonstrated a decrease in AHI from 6.2 to 3.5 (p = 0.057) and an increase in SpO2 from 89.1% to 91.1% (p = 0.091). There were no significant improvements for those in the AT group for either AHI (2.5 to 1.8, p = 0.19) or SpO2 (90.4% to 91.3%, p = 0.46). Normalization of the AHI (AHI < 1) occurred in only one child in each group (7% and 14% of the PAP and AT groups, respectively). CONCLUSIONS The vast majority of children with CFM referred for OSA evaluation are found to have objective evidence of OSA and a quarter of children have moderate-to-severe OSA. It is likely that many children with underlying OSA are not identified and referred for evaluation. Residual OSA after treatment is common in children with CFM.

Abstract
Insomnia is a prevalent sleep disorder that can profoundly impact a person's health and wellbeing. Herbal medicine represents one of the most frequently used complementary and alternative treatments of insomnia. However, the safety and efficacy of herbal medicine for the treatment of this disorder is currently uncertain. In order to ascertain the evidence base for herbal medicine for insomnia, we systematically searched seventeen electronic databases and the reference lists of included studies for relevant randomised controlled trials (RCTs). Fourteen RCTs, involving a total of 1602 participants with insomnia, met the inclusion criteria. Four distinct orally administered herbal monopreparations were identified (i.e., valerian, chamomile, kava and wuling). There was no statistically significant difference between any herbal medicine and placebo, or any herbal medicine and active control, for any of the thirteen measures of clinical efficacy. As for safety, a similar or smaller number of adverse events per person were reported with kava, chamomile and wuling when compared with placebo. By contrast, a greater number of events per person were reported with valerian. While there is insufficient evidence to support the use of herbal medicine for insomnia, there is a clear need for further research in this area.

The aims of this cross-sectional study were to examine the associations between body weight and mental health indicators including depression, social phobia, insomnia, and self-esteem among Taiwanese adolescents in Grades 7-12. The body mass index (BMI) of 5254 adolescents was calculated based on self-reported weight and height measurements. Body weight status was determined by the age- and gender-specific International Obesity Task Force reference tables. By using participants of average weight as the reference group, the association between body weight status (underweight, overweight, and obesity) and mental health indicators (depression, social phobia, insomnia, and self-esteem) were examined by using multiple regression analysis. The possible moderating effects of sociodemographic characteristics on the association were also examined. After controlling for the effects of sociodemographic characteristics, both overweight (p < 0.05) and obese adolescents (p < 0.001) had a lower level of self-esteem than did those of average weight; however, no significant differences in depression, social phobia, or insomnia were found between those who were overweight/obese and those of average weight. No significant differences in the four mental health indicators were found between those who were underweight and those of average weight. Sociodemographic characteristics had no moderating effect on the association between body weight and mental health indicators. In conclusion, mental health and school professionals must take the association between overweight/obesity and self-esteem into consideration when approaching the issue of mental health among adolescents.

Abstract
STUDY OBJECTIVES To examine the patterns of insomnia and sleep-related movement from ages 4.5 to 9 years, their concurrent associations with mental health symptoms in childhood, and the longitudinal associations of sleep-problem persistence with mental health symptoms at ages 9 and 18 years. DESIGN A 14-year prospective follow-up study. Assessments included maternal report on the Children's Sleep Habits Questionnaire at ages 4.5 and 9, and child mental health symptoms via maternal report at age 4.5, multi-informant (child, teacher, mother) report at age 9, and adolescent report at age 18. SETTING Community. PARTICIPANTS A total of 396 children (51% female). INTERVENTIONS N/A. MEASUREMENTS AND RESULTS Sleep problems were more common at age 4.5 than 9; symptoms of insomnia and abnormal sleep movement both had persistence rates of 9-10%. At age 4.5, insomnia was associated with hostile-aggressive and hyperactive-distractible behavior, but there were no significant associations for sleep movement. At age 9, both insomnia and sleep movement were associated with symptoms of depression, externalizing, and attention deficit hyperactivity disorder (ADHD). Insomnia persistence was associated with symptoms of depression, externalizing, and ADHD at age 9 and anxiety and externalizing at age 18; sleep- movement persistence was associated with externalizing and ADHD at age 9, and ADHD at age 18. The age 18 persistence effects for insomnia and anxiety and for sleep movement and ADHD were significant when controlling for earlier mental health. CONCLUSIONS Childhood insomnia and sleep movement are common and associated with mental health symptoms. Their persistence from middle to late childhood predicts associations with specific types of mental health symptoms at age 18.

Abstract
OBJECTIVE To exam the relationship between snoring and morbidities of multiple systems in children. STUDY DESIGN Children with snoring were enrolled and divided into primary snorer (PS) group and obstructive sleep apnea hypopnea syndrome (OSAHS) group based on polysomnography. The healthy children served as the control group. The growth parameters, maxillofacial malformations, blood chemistry, electrocardiogram, and echocardiogram were recorded and intelligence testing was performed in the enrolled children who were ≥6 years old. RESULTS The weight and height were similar in the control group (n = 60) and the PS group (n = 63), but lower in the OSAHS group (n = 89; P < 0.001). Occurrence of adenoidal face and dental malocclusion in the OSAHS and the PS group was significantly higher than that in the control group (P < 0.001). Compared with the control group, the OSAHS group had a lower serum high-density lipoprotein cholesterol level, higher low-density lipoprotein cholesterol level; and a possible higher pulmonary artery pressure based on the echocardiogram (P < 0.001). All the above parameters in the PS group were similar to those in the control group. Full-scale IQ and performance IQ of the OSAHS group was lower (P < 0.001), attention deficits were significantly higher in the OSAHS group (P < 0.001), but were similar in the PS group when compared to the control group. CONCLUSIONS OSAHS in children is associated with delayed growth, maxillofacial malformations, impaired cognitive functions, abnormalities in lipid metabolism, and changes in pulmonary artery pressures. PS children also have higher incidence of maxillofacial malformations but have a normal growth and normal cognitive functions.

Abstract
PURPOSE OF REVIEW The purpose of this review is to examine how sleep disorders in children are affected by age and comorbid medical influences, and to discuss current understanding of how the clinical manifestations, pathophysiology, and treatment of common childhood sleep disorders differ from those of the adult population. RECENT FINDINGS Recently established age-specific norms are required for accurate interpretation of polysomnograms and multiple sleep latency tests in children. SUMMARY Sleep disorders such as insomnia, obstructive sleep apnea, and excessive daytime somnolence are common in both children and adults, but the clinical manifestations and underlying pathophysiology of these disorders vary substantially with age. For example, the bedtime struggles of a temperamental toddler are associated with different symptoms and causative factors compared to psychophysiologic insomnia affecting a middle-aged person. Similarly, a 6-year-old child with obstructive sleep apnea is more likely to exhibit daytime inattention and hyperactivity as a referable daytime symptom than the clear-cut lethargy or sleepiness that most affected adults experience. This review will examine how insomnia, excessive sleepiness, and obstructive sleep apnea differ in children compared to adults.

Abstract
STUDY BACKGROUND Mental health and sleep problems are important public health concerns among adolescents yet little is known about the relationship between sleep, depressive symptoms, and suicidality among American Indian youth. METHODS This study examined the impact of sleep and other factors on depressive symptoms and suicidality among Lumbee American Indian adolescents (N=80) ages 11-18. RESULTS At the bivariate level, sleepiness, was associated with depression but not with suicidality. Time in bed (TIB) was not associated with depression, but more TIB decreased the likelihood of suicidality. Higher levels of depressive symptoms were associated with increased likelihood of suicidality. At the multivariate level, sleepiness, suicidality, and self-esteem were associated with depression. TIB and depressive symptoms were the only variables associated with suicidality. CONCLUSION In working with American Indian youth, it may be helpful to consider sleep patterns as part of a comprehensive assessment process for youth who have or are at risk for depression and suicide.

Abstract
Both chronic pain and sleep problems are common for children with intellectual and developmental disabilities (IDD). Although one study has revealed a relationship between having a medical condition and sleep problems in this population, the role of pain was not examined independently. Thus, the goal of this study was to clarify the specific role of pain in children's sleep problems. Caregivers of 123 children with IDD (67 male; mean age = 10 years, 7 months (SD = 49.7 months)) completed the Children's Sleep Habits Questionnaire (CHSQ) and provided information about children's pain, function and demographic characteristics. Children were grouped as having: No Pain (86), Treated Pain (21), or Untreated Pain (16). A Multivariate Analysis of Variance (MANOVA) indicated children who had pain had significantly more sleep problems overall (F(16, 222) = 2.2, p = .005), and more Night Wakings (F(2, 118) = 3.1, p = .05), Parasomnias (F(2, 118) = 5.0, p = .009) and Sleep Disordered Breathing (F(2, 118) = 5.1, p = .008) in particular. The pattern of sleep problems varied due to whether the child was taking pain medication. Children with pain also had significantly shorter typical sleep duration (F(2, 112) = 3.5, p = 0.035). The presence of sleep problems did not vary due to functional level or whether children were taking sleep medications. However, parents of children who were taking sleep medications reported that both Bedtime Resistance (F(1, 121) = 5.7, p = .019) and Sleep Duration (F(1, 121) = 6.0, p = .016) were more problematic for them. This data indicates pain disrupts sleep in children with IDD even when it is being managed pharmacologically, suggesting pain treatment may not be effective. These results suggest that pain should be considered during evaluation and management of sleep problems in children with IDD.

Abstract
OBJECTIVE To describe the presentation, diagnosis, and treatment of late-onset laryngomalacia in children with obstructive sleep apnea syndrome (OSAS). DESIGN Retrospective study. SETTING Tertiary care children's hospital. PATIENTS Seventy-seven children were identified who had OSAS diagnosed by polysomnography and underwent airway endoscopy to evaluate for laryngomalacia between July 2006 and December 2008. Children with significant neurologic disease or craniofacial malformations were excluded. Seven children under 3 years of age had laryngomalacia and OSAS (Group A), 19 children 3-18 years of age had laryngomalacia and OSAS (Group B), and 51 children 3-18 years of age had OSAS but not laryngomalacia (Group C). MAIN OUTCOME MEASURES Comparison of pre-operative findings, intra-operative findings, interventions, and outcomes between the 3 groups. RESULTS Group A was consistent with previous reports of congenital laryngomalacia with respect to presentation, diagnosis, and treatment. Groups B and C had similar pre-operative findings, including a high incidence of adenotonsillar hypertrophy, and the only significant difference was the intra-operative finding of laryngomalacia in Group B. Treatments were individualized to include supraglottoplasty, adenoidectomy, tonsillectomy, adenotonsillectomy, or a combination of the above. Of the 52 patients who returned in follow-up, 44 noted improvement, but this was rarely confirmed by polysomnogram. CONCLUSIONS Late-onset laryngomalacia may act alone or in concert with additional dynamic or fixed lesions to cause pediatric OSAS. Although there is no specific pre-operative indicator to diagnose late-onset laryngomalacia, it can be readily identified intra-operatively and effectively treated with supraglottoplasty, with or without concurrent adenotonsillectomy.

Abstract
BACKGROUND Obstructive sleep apnea (OSA) is characterized by partial or complete upper airway obstruction during sleep. Approximately 1% to 4% of children are affected by OSA, with adenotonsillar hypertrophy the most common underlying risk factor. Surgical removal of enlarged tonsils and adenoids is the most commonly used treatment for OSA. Given the perioperative risk of the intervention and an estimated recurrence rate of up to 20%, there has recently been an increased interest in non-surgical treatment modalities. As the enlarged adenoids and tonsils consist of hypertrophied lymphoid tissue, anti-inflammatory agents have been proposed as a useful non-invasive treatment option in children with OSA. OBJECTIVES To assess the efficacy of anti-inflammatory drugs for the treatment of OSA in children. SEARCH STRATEGY We identified trials using searches of the Cochrane Airways Group Specialized Register, MEDLINE (1950 to 2010), EMBASE (1988 to 2010), CINAHL (1982 to 2010), CENTRAL (1964 to 2010), Web of Science (1900 to 2010), LILACS (1982 to 2010) and International Pharmaceutical Abstracts (IPA) (1970 to 2010). SELECTION CRITERIA Randomized controlled trials (RCTs) comparing anti-inflammatory drugs against placebo, other anti-inflammatory drugs, or other treatment in children between one and 16 years with objectively diagnosed OSA (Apnea Hypopnea Index (AHI) ≥ 1/hour (h)). DATA COLLECTION AND ANALYSIS Both authors independently performed data extraction and quality assessment. It was not possible to combine data from the included studies; we summarized data in a narrative fashion. MAIN RESULTS We included three RCTs. The first study was a six-week parallel-group trial (25 participants, mean age 3.8 years, mean AHI 10.8/h) of intranasal fluticasone versus placebo showed a statistically significant effect of the drug on improving the AHI. The second study compared intranasal budesonide with placebo in a six-week cross-over trial (62 participants, mean age 8.2 years, mean AHI 3.7/h). The authors reported an advantage of the drug over placebo in reducing the AHI. However, the patients were not analyzed as randomized so the result must be interpreted with caution. No valid group comparisons were reported for the third trial (30 participants, oral montelukast versus placebo in a 12-week parallel-group trial), which has so far only been published as an abstract. AUTHORS' CONCLUSIONS A single small study has found a short-term beneficial effect on the AHI in children with mild to moderate OSA. However, long-term safety and efficacy data are not available yet. Further RCTs are needed to evaluate anti-inflammatory drugs for OSA in children.
