Abstract
Sleep is a fundamental biological necessity, the lack of which has severe repercussions on the mental and physical well-being in individuals of all ages. The phrase "sleep-disordered breathing (SDB)" indicates a wide array of conditions characterized by snoring and/or respiratory distress due to increased upper airway resistance and pharyngeal collapsibility; these range from primary snoring to obstructive sleep apnea (OSA) and occur in all age groups. In the general pediatric population, the prevalence of OSA varies between 2% and 5%, but in some particular clinical conditions, it can be much higher. While adenotonsillar hypertrophy ("classic phenotype") is the main cause of OSA in preschool age (3-5 years), obesity ("adult phenotype") is the most common cause in adolescence. There is also a "congenital-structural" phenotype that is characterized by a high prevalence of OSA, appearing from the earliest ages of life, supported by morpho-structural abnormalities or craniofacial changes and associated with genetic syndromes such as Pierre Robin syndrome, Prader-Willi, achondroplasia, and Down syndrome. Neuromuscular disorders and lysosomal storage disorders are also frequently accompanied by a high prevalence of OSA in all life ages. Early recognition and proper treatment are crucial to avoid major neuro-cognitive, cardiovascular, and metabolic morbidities.

Abstract
The pandemic of the 21st century had a significant influence on the lives of the world population in a negative way. This situation determined a change of lifestyle; it caused the necessity of social isolation for a great number of people. In fact, people tended to avoid crowded environments, social events, to reduce medical checks and sports activities, favoring sedentary life because of fear of the virus. This social attitude brought a high level of stress that worsened many health conditions. This study has the aim of evaluating the possible influence of the pandemic on temporomandibular joint (TMJ) disorders, obstructive sleep apnea syndrome (OSAS) and body mass index (BMI). An anonymized survey, available in two languages (Italian and English), was given to 208 patients from different private dental practices. In this questionnaire, the patients shared experiences about their life during the pandemic. The article highlighted that during this health emergency, there was an increase in body weight in the considered sample. This brought a worsening of OSAS in 65% of patients with a previous diagnosis. Eventually, an increase in TMJ disorders and orofacial pain was reported.

Abstract
Prevalence of childhood obesity is progressively increasing, reaching worldwide levels of 5.6% in girls and of 7.8% in boys. Several evidences showed that obesity is a major preventable risk factor and disease modifier of some respiratory conditions such as asthma and Obstructive Sleep Apnea Syndrome (OSAS). Co-occurrence of asthma and obesity may be due to common pathogenetic factors including exposure to air pollutants and tobacco smoking, Western diet, and low Vitamin D levels. Lung growth and dysanapsis phenomenon in asthmatic obese children play a role in impaired respiratory function which appears to be different than in adults. Genes involved in both asthma and obesity have been identified, though a gene-by-environment interaction has not been properly investigated yet. The identification of modifiable environmental factors influencing gene expression through epigenetic mechanisms may change the natural history of both diseases. Another important pediatric respiratory condition associated with obesity is Sleep-Disordered Breathing (SDB), especially Obstructive Sleep Apnea Syndrome (OSAS). OSAS and obesity are linked by a bidirectional causality, where the effects of one affect the other. The factors most involved in the association between OSAS and obesity are oxidative stress, systemic inflammation, and gut microbiota. In OSAS pathogenesis, obesity's role appears to be mainly due to mechanical factors leading to an increase of respiratory work at night-time. However, a causal link between obesity-related inflammatory state and OSAS pathogenesis still needs to be properly confirmed. To prevent obesity and its complications, family education and precocious lifestyle changes are critical. A healthy diet may lead to an improved quality of life in obese children suffering from respiratory diseases. The present review aimed to investigate the links between obesity, asthma and OSAS, focusing on the available evidence and looking for future research fields.

Abstract
Objective : Habitual snoring is a common problem in children. We evaluated the association between a high risk for sleep-disordered breathing and attention deficit/hyperactivity symptoms. Methods Parents of 13,560 children aged 6 to 12 years responded to questionnaires including items on habitual snoring and the Korean attention deficit/hyperactivity disorder rating scale. The snoring score comprised the number of "yes" responses to habitual-snoring items, and a high risk for sleep-disordered breathing was defined as a snoring score ≥ 2. Results The odds ratio (OR) of a high risk for sleep-disordered breathing was significantly higher in boys (OR = 1.47; p < 0.001), overweight children (OR = 2.20; p < 0.001), and children with current secondhand-smoking exposure (OR = 1.38; p < 0.001). The Korean attention deficit/hyperactivity disorder rating scale score increased significantly with the snoring score (0 vs. 1, B = 1.56, p < 0.001; 0 vs. 2, B = 2.44, p < 0.001; 0 vs. 3, B = 2.48, p < 0.001; 0 vs. 4, B = 3.95; p < 0.001). Conclusion Our study confirms several risk factors of sleep-disordered breathing, namely male sex, overweight, and exposure to tobacco smoking, and found a positive association between habitual snoring and attention deficit/hyperactivity symptoms.

Abstract
Sleep-disordered breathing (SDB) includes disorders of breathing that affect airway patency, which impair children's sleep and lead to negative consequences. Obstructive sleep apnea, hypoventilation and upper airway resistance syndrome are common causes of morbidity and mortality in childhood. These clinical practice guidelines, intended for use by pediatricians and primary care clinicians, provide a clear recommendation for the diagnosis and management of sleep-disordered breathing, focusing on the most serious disorder, obstructive sleep apnea syndrome (OSAS). These clinical guidelines formulate clear recommendations to identify patients with suspected OSAS. Further, the manuscript will highlight the potential consequences of SBD in children, and how to overcome such difficulties, what could be the therapeutic options, a 12 recommendations and what are the future direction for pediatric sleep medicine.

Abstract
Sleep is an important component in a child's growth and development. Snoring is common in children and often perceived as benign, but habitual snoring may be an indication of obstructive sleep apnoea (OSA). OSA can have health, developmental and cognitive consequences. The three common risk factors for paediatric OSA are tonsillar and/or adenoidal hypertrophy, obesity and allergic rhinitis. Primary care providers are well-placed to identify children at risk by screening for habitual snoring and associated OSA risk factors during routine consultations. Physician awareness of OSA symptoms/signs facilitates diagnosis, management and referral decisions. A trial of medical treatment may be considered for habitual snoring with mild symptoms/signs before referral. Overnight polysomnography is the gold standard investigation utilised by paediatric sleep specialists to diagnose OSA. Adenotonsillectomy is the first-line management for OSA with adenotonsillar hypertrophy, but residual/recurrent OSA may occur, so follow-up by primary care providers is important after surgery.

Abstract
INTRODUCTION This study aimed to investigate the trend and seasonality of infection due to respiratory syncytial virus (RSV) at KK Women's and Children's Hospital (KKH) in Singapore and to examine the risk factors for mortality among children with RSV infection requiring admission to the paediatric intensive care unit (PICU). METHODS A retrospective study was conducted at KKH on children with RSV infections who were admitted to the PICU between January 2004 and December 2010. The medical records of children who died from RSV infections were reviewed. Linear regression was performed to determine the risk factors of RSV mortality. RESULTS RSV infection was documented in 5,785 children during the study period, occurring throughout the year, with a small increase in prevalence between the months of June and August annually. Among 85 (1.5%) of 5,785 children who were admitted to the PICU for RSV infection, 74 (1.3%) survived and there were 11 (0.2%) deaths. Multivariate logistic regression analysis showed that significant haemodynamically significant cardiac disease (odds ratio [OR] 12.2, 95% confidence interval [CI] 0.9-16.7, p = 0.05), immunodeficiency (OR 71.4, 95% CI 8.2-500, p < 0.001) and metabolic disease (OR 71.4, 95% CI 4.3-1,000, p = 0.003) were independent risk factors for mortality in RSV infections. Prematurity increased the risk of admission to the PICU but was not significantly associated with mortality. CONCLUSION Children with haemodynamically significant cardiac disease, immunodeficiency and metabolic disease were at higher risk of death after hospitalisation for RSV-related illnesses. These children should be considered for palivizumab prophylaxis.

Abstract
OBJECTIVE This study aimed to identify the heterogeneity of obstructive sleep apnea syndrome clinical presentation in children. PARTICIPANTS Children who were 3-14 years old and with obstructive sleep apnea syndrome after polysomnography monitoring (apnea and hypopnea index>5 or obstructive apnea index>1) in the sleep center of Beijing Children's Hospital were included. METHODS A sleep disorder questionnaire including different combinations of symptoms and co-morbidities of obstructive sleep apnea syndrome in children was used. A cluster analysis was used to classify the data. RESULTS The apnea hypopnea index alone is not adequate to predict clinical phenotypes. Based on symptoms and co-morbidities of obstructive sleep apnea syndrome, three distinct clusters were identified. They were "nocturnal snoring and daytime sleepiness group" (cluster 1), "hyperactivity group" (cluster 2), and "minimally symptomatic group" (cluster 3). A prediction model was built according to eight variables which showed statistical significance by pairwise comparison among clusters. Overall accuracy of the prediction model could reach 86%. Both the sensitivity and specificity of cluster 2 and 3 prediction were around 90%. CONCLUSION Children with obstructive sleep apnea syndrome have different patterns of clinical presentation and the identification of the different clinical profiles of obstructive sleep apnea syndrome can provide clues for more personalised diagnoses and therapies.

Abstract
Obesity in pediatric population is an important global problem. The prevalence of obesity in children is dramatically rising. According to World Health Organization, about 41 million children under the age of 5 years are obese or overweight worldwide. Overweight and obesity are well-known risk factors for a number of health disorders. Diseases commonly observed in this group of patients are metabolic disorders, type 2 diabetes mellitus, cardiovascular diseases, fatty liver disease, musculoskeletal problems, and many others. The main aim of this study was to present the current knowledge of the association between childhood obesity and common otorhinolaryngological disorders. It is suggested that obese children are more prone to suffer from otorhinolaryngological illnesses than the lean ones. Obesity may predispose to otorhinolaryngological diseases in various ways. It strongly interferes with the immune system (increases serum levels of interleukin 6, tumor necrosis factor, C-reactive protein, and leptin and reduces adiponectin concentration) affecting organs of the upper respiratory tract. Additionally, obesity induces mechanical disorders in the upper airways. According to our review, obesity predisposes to otitis media with effusion, acute otitis media, recurrent otitis media, obstructive sleep apnea, sensorineural hearing loss, adenotonsillar hypertrophy, and post-/perioperative complications after adenotonsillectomy. Obesity in children significantly correlates with both obstructive sleep apnea (OSA) and asthma and constitutes a significant component of "OSA, obesity, asthma" triad.

Abstract
Objectives Pediatric sleep-disordered breathing (SDB) is a common debilitating disorder that can adversely affect the attention and academic performance of school-age children. Unfortunately, only a few studies have examined the effect of SDB treatment on attention in pediatric populations. Therefore, the aim of this study was to prospectively investigate the effect of SDB treatment on attention in children. Methods This study consecutively enrolled SDB children with adenotonsillar hypertrophy. All subjects underwent standard-of-care treatment (adenotonsillectomy or close observation) and were evaluated using a computerized comprehensive attention test at the initial visit. Comprehensive attention tests consisted of both sustained and divided attention tasks. Each completed task was assigned an attention score, which was based on the number of omission or commission errors. The comprehension attention test was repeated 1 year later. Results A total of 171 children who underwent adenotonsillectomy and 32 children who did not undergo adenotonsillectomy were included in this study. At baseline, there was no significant difference according to the score of all type comprehension attention tests between children in the adenotonsillectomy group and in the observation group. One year after treatment, children in the adenotonsillectomy group had significantly improved scores in all attention tasks. Children in the observation group had only significant improvement in omission errors on sustained attention tasks. Meanwhile, the attention score based on commission errors of divided attention tasks was significantly worse than at baseline for those. Conclusion Our study showed that adenotonsillectomy may be helpful in improving attention in children with SDB.

Abstract
BACKGROUND Adenotonsillectomy (AT) has been an effective treatment for sleep-disordered breathing (SDB) in children, and several studies described the risk of postoperative weight gain and obesity in children treated with AT. The present study aimed to evaluate behavioral improvements in children with SDB one year after adenotonsillectomy and to investigate an influence of postoperative weight gain on behaviors. METHODS The study included 170 children aged 5-11 years who underwent adenotonsillectomy for SDB and 150 controls. Body mass index percentile was obtained for age and gender, and parental sleep-related breathing disorder (SRBD) questionnaire was used to assess the severity of SDB. Psychological assessment was performed pre- and post-adenotonsillectomy using standardized questionnaires including strength and difficulties questionnaire, children's depression inventory and screen for child anxiety-related emotional disorder. RESULTS The mean age of 170 patients was 7.7 ± 1.5 years with 73 (42.9%) girls and 97 (57.1%) boys. The mean follow-up period were 15.4 ± 2.7 months. The patients had shown significant improvements in SDB scores as well as in questionnaire-based behavioral problems after adenotonsillectomy. The odds of a child being overweight were significantly increased after adenotonsillectomy. Less improvements in hyperactivity and conduct problems were observed in the patients with older ages, higher SRBD scores, and overweight/obesity at 1-year follow-up after adenotonsillectomy. CONCLUSION These data suggest that abnormal behavioral outcomes should be evaluated postoperatively, which potentially could be reduced with the early adenotonsillectomy and adequate postoperative weight control.

Abstract
INTRODUCTION Both sleep-disordered breathing (SDB) and high blood pressure (BP) occur more frequently among obese children than among normal weight children, and this may be due to endothelial dysfunction and worsened arterial stiffness. The aim of this study was to evaluate the possible association between SDB and BP, and the possible role of endothelial function and local and systemic arterial stiffness in a sample of obese children asymptomatic for sleep disturbances. MATERIALS AND METHODS Thirty-nine obese children were included in the study. Children underwent overnight limited channel polysomnography, and the vascular measurements included the following: office and 24-h ambulatory BP; brachial flow-mediated dilatation, carotid intima-media thickness and carotid distensibility measured using ultrasound; and systemic arterial stiffness index measured using digital volume pulse analysis. RESULTS Significant correlations between different BP measurements (both office and ambulatory BP monitoring and estimated by Z score) and SDB were found, including correlations involving the respiratory disturbance index, the apnea-hypopnea index (AHI), the number of desaturations per hour and the mean peripheral saturation (r ranging between 0.330 and 0.474). Carotid distensibility was correlated with the AHI (r = -0.367; P = 0.030) and with the mean oxygen saturation (r = 0.401; P = 0.017). In contrast, there was no relationship among flow-mediated dilatation, stiffness index, carotid intima-media thickness and all the tested respiratory markers. In the multivariate analysis, the supine Z SBP remained independently associated with the number of desaturations per hour and the AHI, even after correction for carotid distensibility and BMI. CONCLUSION Our data suggest that in obese children asymptomatic for sleep respiratory problems, SDB might worsen BP, in part, through an increase in arterial stiffness.

Abstract
Increasing prevalence of hypertension (HTN) in children and adolescents has become a significant public health issue driving a considerable amount of research. Aspects discussed in this document include advances in the definition of HTN in 16 year or older, clinical significance of isolated systolic HTN in youth, the importance of out of office and central blood pressure measurement, new risk factors for HTN, methods to assess vascular phenotypes, clustering of cardiovascular risk factors and treatment strategies among others. The recommendations of the present document synthesize a considerable amount of scientific data and clinical experience and represent the best clinical wisdom upon which physicians, nurses and families should base their decisions. In addition, as they call attention to the burden of HTN in children and adolescents, and its contribution to the current epidemic of cardiovascular disease, these guidelines should encourage public policy makers to develop a global effort to improve identification and treatment of high blood pressure among children and adolescents.

Abstract
Background: Obstructive sleep apnea (OSA) syndrome has a negative impact on the health of millions of adolescents and youth. The aim of this study was to evaluate the associations of OSA syndrome with obesity and cardiometabolic risk factors among adolescents and youth at risk for metabolic syndrome (MS). Methods: A total of 558 subjects aged 14–28 years were recruited from the Beijing Child and Adolescent Metabolic Syndrome Study. Each underwent a 2-h oral glucose tolerance test (OGTT), echocardiography, and liver ultrasonography. Anthropometric measures, blood levels of glucose, lipids, and liver enzymes were assessed. Subjects with high or low risk for OSA were identified by Berlin Questionnaire (BQ). Results: Among the subjects in obesity, 33.7% of whom were likely to have OSA by BQ. Subjects with high risk for OSA had higher neck and waist circumference and fat mass percentage compared to those with low risk for OSA (P < 0.001). Moreover, significant differences in levels of lipids, glucose after OGTT, and liver enzymes, as well as echocardiographic parameters were found between the two groups with high or low risk for OSA (P < 0.05). The rates of nonalcoholic fatty liver disease (71.0% vs. 24.2%), MS (38.9% vs. 7.0%), and its components in high-risk group were significantly higher than in low-risk group. Conclusions: The prevalence of OSA by BQ was high in obese adolescents and youth. A high risk for OSA indicates a high cardiometabolic risk. Mechanisms mediating the observed associations require further investigation.

Abstract
AIMS The aim of this study was to identify factors that predict risk of obstructive sleep apnoea (OSA) in obese children, which could aid in prioritising sleep studies. METHODS A retrospective chart review was undertaken of obese children seen in the KOALA weight management clinic and Sleep clinic. Data collected included demographics, clinical history, examination findings, biochemical markers, and polysomnogram results. RESULTS Two hundred seventy-two obese children were seen in the KOALA clinic out of which 54 (20%) were also seen in the Sleep clinic because of snoring. Thirty-two were referred by the KOALA clinic; the remaining 22 were referred by other medical practitioners prior to being seen in the KOALA clinic. Thirty-nine had polysomnograms. The time from referral to Sleep clinic ranged from 10 days to 1.5 years with 50% seen within 6 months; with similar time gap between the blood tests and time of polysomnograms. Thirty-six percent (14/39) were reported to have OSA. Six children were Aboriginal/Torres Strait Islander (ATSI) and all had OSA, which was statistically significant (P = 0.004). There was a statistically significant correlation between high-sensitivity C-reactive protein (hs-CRP) and obstructive event index (OEI) in rapid eye movement (REM) sleep. (r = 0.50, P = 0.04). Correlation between low-density lipoprotein (LDL) and OEI in REM was r = 0.36, P = 0.06, which approached significance. CONCLUSIONS Ethnicity was a significant factor with more obese ATSI children having OSA. The significant correlation between hs-CRP with OEI is consistent with findings of previous studies. Several factors (glycosylated haemoglobin, LDL) approached significance.

Abstract
UNLABELLED This study investigated the association between obesity and obstructive sleep apnea (OSA) in preschool and school-age children. Parents of obese and randomly chosen normal weight children completed a questionnaire on sleep-related symptoms, demography, family, and medical history. All subjects were invited to undergo polysomnography (PSG). OSA cases were defined as obstructive apnea hypopnea index (OAHI) ≥1. A total of 5930 children were studied with 9.5% obese (11.9% boys/6.1% girls), 205/2680 preschool and 360/3250 school children. There were 1030 children (535 obese/495 normal weight) who underwent PSG. OSA was higher in obese children and obese school children had higher OAHI, arousal index, and shorter total sleep time. However, there was no positive correlation between OSA and body mass index (BMI). The main risk factors for OSA in preschool children were adenotonsillar hypertrophy and recurrent respiratory tract infection. The main cause for OSA in school children was a history of parental snoring and obesity. Mallampati scores and sleep-related symptoms were found to be associated with OSA in both preschool and school children. CONCLUSION We demonstrated differential risk factors for OSA in obese children, which suggest that a different mechanism may be involved in OSA development in preschool and school-age children. WHAT IS KNOWN Various risk factors have been reported in obese children with OSA owing to the different age and different study design. Obese children have a higher prevalence and severity of obstructive sleep apnea (OSA). OSA risk factors in obese children are affected by different ages and study designs. WHAT IS NEW A differential prevalence and risk factors for obese preschool and school-age children with OSA has been demonstrated.

Abstract
PURPOSE Obesity and biochemical parameters of metabolic disorders are both closely related to obstructive sleep apnea (OSA). The aim of this study was to compare sleep architecture and OSA in obese children with and without metabolic syndrome. METHODS Forty-two children with metabolic syndrome were selected as case group and 38 children without metabolic syndrome were matched for age, sex, and BMI as control group. The standardized Persian version of bedtime problems, excessive daytime sleepiness, awakenings during the night, regularity and duration of sleep, snoring (BEARS) and Children's Sleep Habits Questionnaires were completed, and polysomnography (PSG) was performed for all study subjects. Scoring was performed using the manual of American Academy of Sleep Medicine for children. Data were analyzed using chi-square test, T test, Mann-Whitney U test, and logistic regression analysis. RESULTS Non-rapid eye movement (NREM) sleep and N1 stage in the case group were significantly longer than the control group, while REM sleep was significantly shorter. Waking after sleep onset (WASO) was significantly different between two groups. Severe OSA was more frequent in the control group. Multivariate logistic regression analysis showed that severe OSA (OR 21.478, 95 % CI 2.160-213.600; P = 0.009) and REM sleep (OR 0.856, 95 % CI 0.737-0.994; P = 0.041) had independent association with metabolic syndrome. CONCLUSIONS Obese children with metabolic syndrome had increased WASO, N1 sleep stage, and severe OSA. But the results regarding sleep architecture are most likely a direct result of OSA severity. More longitudinal studies are needed to confirm the association of metabolic syndrome and OSA.

Abstract
OBJECTIVE Many youth struggle with adherence to bilevel noninvasive ventilation (NIV), often shortly after initiation of treatment. Anecdotal evidence suggests youths with comorbid obesity struggle with adherence while youths with comorbid neuromuscular disease demonstrate better adherence rates. The objective of this study was to explore factors relating to bilevel NIV adherence, and to compare these between youths with underlying obesity or neuromuscular disease. METHODS An exploratory qualitative approach was used to examine youth and caregivers' experiences with and perceptions of bilevel NIV. Semi-structured interviews (n = 16) of caregivers and youths were conducted. Youths 12 years and older with nocturnal hypoventilation diagnosed on polysomnography and managed with bilevel NIV, with either concurrent obesity or neuromuscular disease were included. Thematic analysis of interview data was conducted using qualitative analysis software. RESULTS Factors associated with positive bilevel NIV adherence included previous encouraging experiences with therapy; subjective symptom improvement; familiarity with medical treatments; understanding of nocturnal hypoventilation and its consequences; family and health-care team support; and early adaptation to treatments. Factors associated with poor bilevel NIV adherence included previous negative experiences with therapy, negative attitude towards therapy; difficulty adapting; perceived lack of support from family or health-care team; fear/embarrassment regarding treatment; caregivers not being health-minded; technical issues; side effects; and a lack of subjective symptom improvement. CONCLUSIONS The dimensions which most affect adherence to bilevel NIV are those which contribute to youths' conception of feeling "well" or "unwell." Adherence to treatment may hinge largely on the way in which NIV is initially experienced and framed. COMMENTARY A commentary on this article appears in this issue on page 1355.

Abstract
RATIONALE Structural risk factors for obstructive sleep apnea syndrome (OSAS) in adolescents have not been well characterized. Because many adolescents with OSAS are obese, we hypothesized that the anatomic OSAS risk factors would be more similar to those in adults than those in children. OBJECTIVES To investigate the anatomic risk factors in adolescents with OSAS compared with obese and lean control subjects using magnetic resonance imaging (MRI). METHODS Three groups of adolescents (age range: 12-16 yr) underwent MRI: obese individuals with OSAS (n = 49), obese control subjects (n = 38), and lean control subjects (n = 50). MEASUREMENTS AND MAIN RESULTS We studied 137 subjects and found that (1) obese adolescents with OSAS had increased adenotonsillar tissue compared with obese and lean control subjects; (2) obese OSAS adolescents had a smaller nasopharyngeal airway than control subjects; (3) the size of other upper airway soft tissue structures (volume of the tongue, parapharyngeal fat pads, lateral walls, and soft palate) was similar between subjects with OSAS and obese control subjects; (4) although there were no major craniofacial abnormalities in most of the adolescents with OSAS, the ratio of soft tissue to craniofacial space surrounding the airway was increased; and (5) there were sex differences in the pattern of lymphoid proliferation. CONCLUSIONS Increased size of the pharyngeal lymphoid tissue, rather than enlargement of the upper airway soft tissue structures, is the primary anatomic risk factor for OSAS in obese adolescents. These results are important for clinical decision making and suggest that adenotonsillectomy should be considered as the initial treatment for OSAS in obese adolescents, a group that has poor continuous positive airway pressure adherence and difficulty in achieving weight loss.

Abstract
Adenotonsillectomy (A&T) is a very common surgical procedure in children. Over the past 20 years the principal indication for A&T in children has changed from recurrent adenotonsillitis to obstructive sleep apnea. The physiopathology of obstructive sleep apnea syndrome (OSAS) is multifactorial and obesity has been shown to be one of the main factors correlated with its occurrence. On the other hand, the prevalence and severity of childhood obesity have become a veritable epidemic problem in the past 30 years. So the increasing prevalence of obesity in children and high prevalence of obstructive sleep apnea in obese children implies that an increasing number of these children will present for A&T. Due to more prevalent anatomical alterations of the oronasopharyngeal airways, it is often difficult to predict operation success in obese children. However, previous studies supports that although the risk of presence of residual symptoms of OSAS and airway-related perioperative complication in obese may be more than nonobese group, A&T is effective to reduce obstructive symptoms and improve quality of life in obese children with OSAS.

Abstract
OBJECTIVES Adenotonsillar hypertrophy is the major determinants of habitual snoring in pediatric population. Behavioral hyperactivity and schooling problems have been repeatedly reported in these children, and it may underlie more extensive behavioral disturbances, particularly for the obese children. The aim of the present study is to evaluate the incidence and characteristics of emotional and behavioral problems using outpatient-based psychological screening tools in the children with habitual snoring. METHODS Total 235 patients and 170 controls, who aged 4-9 years were enrolled. Body mass index (BMI) z-score was obtained for age and gender and parental sleep-related breathing disorder (SRBD) questionnaire was used to assess severity of sleep-disordered breathing (SBD). Psychological assessment was performed using standardized questionnaires including Strength and Difficulties Questionnaire (SDQ), Children's Depression Inventory (CDI) and Screen for Child Anxiety Related Emotional Disorders (SCARED). RESULTS Children presenting habitual snoring had significantly higher mean scores on almost all scales of SDQ, and SCARED than community controls. Around 20% of the children with habitual snoring, compared with 10-11% of controls had significant levels of distress that could adversely impact treatment outcomes. There was no interaction between obstructive sleep apnea severity and behavioral ratings. The scores for emotional distress and hyperactivity were more prominent in the obese children. Significant psychological distress or impairment in social interactions was observed in children with higher SRBD scores. CONCLUSIONS Our findings suggest that the presence of habitual snoring in young children is associated wide spectrum of behavioral problems and the level of psychological distress might be evaluated at the time of the diagnosis.

Abstract
Severe obesity afflicts between 4% and 6% of all youth in the United States, and the prevalence is increasing. Despite the serious immediate and long-term cardiovascular, metabolic, and other health consequences of severe pediatric obesity, current treatments are limited in effectiveness and lack widespread availability. Lifestyle modification/behavior-based treatment interventions in youth with severe obesity have demonstrated modest improvement in body mass index status, but participants have generally remained severely obese and often regained weight after the conclusion of the treatment programs. The role of medical management is minimal, because only 1 medication is currently approved for the treatment of obesity in adolescents. Bariatric surgery has generally been effective in reducing body mass index and improving cardiovascular and metabolic risk factors; however, reports of long-term outcomes are few, many youth with severe obesity do not qualify for surgery, and access is limited by lack of insurance coverage. To begin to address these challenges, the purposes of this scientific statement are to (1) provide justification for and recommend a standardized definition of severe obesity in children and adolescents; (2) raise awareness of this serious and growing problem by summarizing the current literature in this area in terms of the epidemiology and trends, associated health risks (immediate and long-term), and challenges and shortcomings of currently available treatment options; and (3) highlight areas in need of future research. Innovative behavior-based treatment, minimally invasive procedures, and medications currently under development all need to be evaluated for their efficacy and safety in this group of patients with high medical and psychosocial risks.

Abstract
INTRODUCTION The obstructive sleep apnea syndrome (OSAS) is associated with increased visceral adipose tissue (VAT) in adults; however, few studies have evaluated VAT in relation to upper airway function in adolescents. We hypothesized that increased neck circumference (NC) and VAT would be associated with increased upper airway collapsibility. METHODS Adolescents (24 obese patients with OSAS, 22 obese control patients, and 29 lean control patients) underwent abdominal magnetic resonance imaging, and measurement of upper airway pressure-flow relationships in the activated and hypotonic upper airway states. RESULTS Patients with OSAS had a greater activated slope of the pressure-flow relationship (SPF) than control groups (P < 0.001), whereas hypotonic SPF was greater in both obese groups compared with lean control patients (P = 0.01). NC and VAT were greater in obese control patients and those with OSAS than in lean control patients (P < 0.001), but did not differ between obese patients with OSAS and obese control patients. In lean control patients and those with OSAS, increased NC was associated with increased activated SPF, whereas in obese control patients it was associated with decreased activated SPF (P = 0.03). In contrast, increased NC was associated with increased hypotonic SPF in all groups (P < 0.001). There was no significant effect of VAT on either activated or hypotonic SPF for any of the three groups. CONCLUSIONS Increased neck circumference was associated with increased upper airway collapsibility in adolescents in the hypotonic but not activated state. These data suggest that obese adolescents without OSAS, despite a narrowed upper airway from adipose tissue, are protected from developing OSAS by upper airway neuromotor activation. Neither neck circumference nor visceral adipose tissue is useful in predicting upper airway collapsibility in obese adolescents.

Abstract
AIMS To evaluate the impact of obesity on clinical and sleep characteristics in a population of narcoleptic children. METHODS Data from the children diagnosed with idiopathic narcolepsy in the National Reference Centers for Narcolepsy were collected between 2008 and 2011. Clinical and electrophysiological characteristics were compared between obese (body mass index [BMI] greater than P97) and nonobese children. RESULTS The 117 children (65 boys, 59 de novo patients) had a mean age of 11.6 ± 3.1 years on diagnosis. Cataplexy was present in 81%, DQB1*0602 in 91%. Mean BMI was 23.2 ± 5.2 kg/m(2) and BMI z-score was 2.9 ± 2.6. Obesity was found in 60% with a similar prevalence in treated versus de novo patients and in patients with and without cataplexy. Sleepiness and cataplexy started earlier in obese children. Obese narcoleptic children had lower sleep efficiency, higher apnea hypopnea index and respiratory arousals index (RAI) than nonobese children. BMI z-score was positively correlated with RAI. Obese children were more tired and missed more often school than nonobese children. CONCLUSION Obesity affects more than 50% of narcoleptic children, mostly younger at disease onset, and has a deleterious impact on sleep quality as well as on school attendance.

Abstract
Obstructive Sleep Apnoea (OSA) is increasingly recognised as a condition that not only causes excessive daytime sleepiness, but is also an important cardiovascular risk factor. Treatment of OSA should include conservative measures such as weight loss and positional therapy, the nuances of which are discussed in this article. However this in itself is not sufficient treatment for most patients. The first line of treatment for OSA that is recommended across the entire spectrum of disease is continuous positive airway pressure (CPAP) therapy. Indications for initiating CPAP are discussed, as well as possible alternatives to CPAP such as surgery or dental devices. In initiating CPAP treatment, machine-patient interface needs to be carefully considered, as there is a wide range of masks available. Factors to be considered in the choice of CPAP machine and mode are discussed. Finally, patient-specific factors such as patient acceptance of treatment, common problems encountered in CPAP follow-up and the importance of patient education are addressed.

Abstract
BACKGROUND Obstructive sleep apnea (OSA) is associated with obesity, inflammation, and insulin resistance. The role of fat distribution in OSA pathogenesis has not been established in children. The objective of the study is to examine the relationship between fat distribution, OSA, and insulin resistance in an unselected population of obese children. METHODS All obese (BMI > 95th percentile) children (ages 5-18 y) seen at a pediatric obesity clinic were invited to participate. Subjects underwent polysomnography, and were tested for dyslipidemia, inflammation, and insulin resistance measured by the homeostasis model assessment (HOMA). In a subset of subjects, magnetic resonance (MRI) imaging was used to determine the abdominal visceral and subcutaneous adipose tissue areas and magnetic resonance spectroscopy (MRS) spectroscopy was used to intramyocellular lipids in leg muscles. MEASUREMENTS AND MAIN RESULTS 31 obese subjects enrolled and completed polysomnography and serum testing, and 19 subjects underwent MRI/MRS. The mean age was 12.6 ± 3.0 y and the mean body mass index (BMI) was 39.5 ± 11.2 kg/m(2). Forty-eight percent had OSA (mean apnea hypopnea index [AHI] 6.26 ± 6.77 events/h) Subjects with OSA had significantly increased BMI, log HOMA, triglycerides, and leptin compared to those without OSA. In regression analysis, only BMI z-score was associated with log HOMA. In the subset of patients with imaging data, visceral fat area was strongly predictive of AHI (p = 0.003, r(2) = 0.556). BMI z-score, gender, and age were not predictive. CONCLUSIONS Visceral fat distribution is independently predictive of OSA severity in obese children.

Abstract
OBJECTIVE This comprehensive, evidence-based review provides a systematic analysis of the literature regarding the validity, reliability, and clinical utility of polysomnography for characterizing breathing during sleep in children. Findings serve as the foundation of practice parameters regarding respiratory indications for polysomnography in children. METHODS A task force of content experts performed a systematic review of the relevant literature and graded the evidence using a standardized grading system. Two hundred forty-three evidentiary papers were reviewed, summarized, and graded. The analysis addressed the operating characteristics of polysomnography as a diagnostic procedure in children and identified strengths and limitations of polysomnography for evaluation of respiratory function during sleep. RESULTS The analysis documents strong face validity and content validity, moderately strong convergent validity when comparing respiratory findings with a variety of relevant independent measures, moderate-to-strong test-retest validity, and limited data supporting discriminant validity for characterizing breathing during sleep in children. The analysis documents moderate-to-strong test-retest reliability and interscorer reliability based on limited data. The data indicate particularly strong clinical utility in children with suspected sleep related breathing disorders and obesity, evolving metabolic syndrome, neurological, neurodevelopmental, or genetic disorders, and children with craniofacial syndromes. Specific consideration was given to clinical utility of polysomnography prior to adenotonsillectomy (AT) for confirmation of obstructive sleep apnea syndrome. The most relevant findings include: (1) recognition that clinical history and examination are often poor predictors of respiratory polygraphic findings, (2) preoperative polysomnography is helpful in predicting risk for perioperative complications, and (3) preoperative polysomnography is often helpful in predicting persistence of obstructive sleep apnea syndrome in patients after AT. No prospective studies were identified that address whether clinical outcome following AT for treatment of obstructive sleep apnea is improved in association with routine performance of polysomnography before surgery in otherwise healthy children. A small group of papers confirm the clinical utility of polysomnography for initiation and titration of positive airway pressure support. CONCLUSIONS Pediatric polysomnography shows validity, reliability, and clinical utility that is commensurate with most other routinely employed diagnostic clinical tools or procedures. Findings indicate that the "gold standard" for diagnosis of sleep related breathing disorders in children is not polysomnography alone, but rather the skillful integration of clinical and polygraphic findings by a knowledgeable sleep specialist. Future developments will provide more sophisticated methods for data collection and analysis, but integration of polysomnographic findings with the clinical evaluation will represent the fundamental diagnostic challenge for the sleep specialist.

Abstract
BACKGROUND There has been marked expansion in the literature and practice of pediatric sleep medicine; however, no recent evidence-based practice parameters have been reported. These practice parameters are the first of 2 papers that assess indications for polysomnography in children. This paper addresses indications for polysomnography in children with suspected sleep related breathing disorders. These recommendations were reviewed and approved by the Board of Directors of the American Academy of Sleep Medicine. METHODS A systematic review of the literature was performed, and the American Academy of Neurology grading system was used to assess the quality of evidence. RECOMMENDATIONS FOR PSG USE: 1. Polysomnography in children should be performed and interpreted in accordance with the recommendations of the AASM Manual for the Scoring of Sleep and Associated Events. (Standard) 2. Polysomnography is indicated when the clinical assessment suggests the diagnosis of obstructive sleep apnea syndrome (OSAS) in children. (Standard) 3. Children with mild OSAS preoperatively should have clinical evaluation following adenotonsillectomy to assess for residual symptoms. If there are residual symptoms of OSAS, polysomnography should be performed. (Standard) 4. Polysomnography is indicated following adenotonsillectomy to assess for residual OSAS in children with preoperative evidence for moderate to severe OSAS, obesity, craniofacial anomalies that obstruct the upper airway, and neurologic disorders (e.g., Down syndrome, Prader-Willi syndrome, and myelomeningocele). (Standard) 5. Polysomnography is indicated for positive airway pressure (PAP) titration in children with obstructive sleep apnea syndrome. (Standard) 6. Polysomnography is indicated when the clinical assessment suggests the diagnosis of congenital central alveolar hypoventilation syndrome or sleep related hypoventilation due to neuromuscular disorders or chest wall deformities. It is indicated in selected cases of primary sleep apnea of infancy. (Guideline) 7. Polysomnography is indicated when there is clinical evidence of a sleep related breathing disorder in infants who have experienced an apparent life-threatening event (ALTE). (Guideline) 8. Polysomnography is indicated in children being considered for adenotonsillectomy to treat obstructive sleep apnea syndrome. (Guideline) 9. Follow-up PSG in children on chronic PAP support is indicated to determine whether pressure requirements have changed as a result of the child's growth and development, if symptoms recur while on PAP, or if additional or alternate treatment is instituted. (Guideline) 10. Polysomnography is indicated after treatment of children for OSAS with rapid maxillary expansion to assess for the level of residual disease and to determine whether additional treatment is necessary. (Option) 11. Children with OSAS treated with an oral appliance should have clinical follow-up and polysomnography to assess response to treatment. (Option) 12. Polysomnography is indicated for noninvasive positive pressure ventilation (NIPPV) titration in children with other sleep related breathing disorders. (Option) 13. Children treated with mechanical ventilation may benefit from periodic evaluation with polysomnography to adjust ventilator settings. (Option) 14. Children treated with tracheostomy for sleep related breathing disorders benefit from polysomnography as part of the evaluation prior to decannulation. These children should be followed clinically after decannulation to assess for recurrence of symptoms of sleep related breathing disorders. (Option) 15. Polysomnography is indicated in the following respiratory disorders only if there is a clinical suspicion for an accompanying sleep related breathing disorder: chronic asthma, cystic fibrosis, pulmonary hypertension, bronchopulmonary dysplasia, or chest wall abnormality such as kyphoscoliosis. (Option) RECOMMENDATIONS AGAINST PSG USE: 16. Nap (abbreviated) polysomnography is not recommended for the evaluation of obstructive sleep apnea syndrome in children. (Option) 17. Children considered for treatment with supplemental oxygen do not routinely require polysomnography for management of oxygen therapy. (Option) CONCLUSIONS Current evidence in the field of pediatric sleep medicine indicates that PSG has clinical utility in the diagnosis and management of sleep related breathing disorders. The accurate diagnosis of SRBD in the pediatric population is best accomplished by integration of polysomnographic findings with clinical evaluation.

Abstract
BACKGROUND The association of obesity with sleep-associated respiratory disturbances, which has traditionally been described as a problem in adults, actually originates in childhood. We sought an association between sleep-disordered breathing (SDB) and overweight and/or obesity in a large cohort of school- and preschool-aged children in Southern Italy. METHODS One thousand two hundred seven children (612 girls and 595 boys; mean age 7.3 years) were screened by self-administered questionnaires. According to answers, subjects were divided into three groups: nonsnorers (NS), occasional snorers (OS), and habitual snorers (HS). All HS, who also failed an oximetry study at home, underwent polysomnographic monitoring for the definition of SDB. BMI was calculated according to Italian growth charts. RESULTS A total of 809 subjects (67.0%) were eligible for the study. Of them, 44 subjects (5.4%) were classified as HS, 138 (17.0%) as OS, and 627 (77.5%) as NS. Fourteen subjects (1.7%) were given a diagnosis of obstructive sleep apnea syndrome (OSAS). Sixty-four subjects (7.9%) were defined as obese, 121 (14.9%) as overweight, and 624 (77.2%) as normal weight. The frequency of HS was significantly higher in obese subjects than in overweight and normal-weight subjects (12.5% vs 5.8% vs 4.6%, respectively; P = .02), whereas the frequency of OSAS was 1.6% in normal-weight, 1.6% in overweight, and 3.1% in obese subjects (P = not significant). CONCLUSIONS Our findings in a large sample of Italian children suggest that obesity is associated with snoring.

Abstract
OBJECTIVE The behaviors of children may be affected by sleep-disordered breathing (SDB). This study adopts a cross-sectional approach to investigate the relationship between the sleep apneas-hypopneas index during sleep and the behavioral and academic performance of schoolchildren in Taiwan. METHODS A total of 138 children (85 boys and 53 girls), ages 6-11, were recruited from two elementary schools to participate in this study. Overnight polysomnographic examinations in hospital were performed to assess sleep quality, including total sleep time, arousal index, apneas-hypopneas index, desaturation index, and lowest oxygen saturation, as well as the percentage of total sleep time spent in rapid eye movement, stage 1, stage 2, stage 3, and stage 4. The children's parents and teachers were required to complete a Chinese version of the Child Behavior Checklist and Teacher's Report Form to assess child behavior and academic achievement. RESULTS Compared with children without SDB (apneas-hypopneas index ≤1), those with severe SDB (apneas-hypopneas index >15) exhibited more irregular behavioral performance in somatic complaints (odds ratio (OR) = 9.43; 95% confidence interval (CI) = 1.04-85.71) and attention (OR = 9.95; 95% CI = 1.02-97.00). However, different severities of SDB groups did not show significant associations in academic performance. CONCLUSION Our study suggests that children with severe SDB may predispose to somatic complaints and attention problems so that sleep examination or medical intervention might be provided at an early age in these children.

Abstract
The increasing prevalence of obesity in children seems to be associated with an increased prevalence of obstructive sleep apnea syndrome (OSAS) in children. Possible pathophysiological mechanisms contributing to this association include the following: adenotonsillar hypertrophy due to increased somatic growth, increased critical airway closing pressure, altered chest wall mechanics, and abnormalities of ventilatory control. However, the details of these mechanisms and their interactions have not been elucidated. In addition, obesity and OSAS are both associated with metabolic syndrome, which is a constellation of features such as hypertension, insulin resistance, dyslipidemia, abdominal obesity, and prothrombotic and proinflammatory states. There is some evidence that OSAS may contribute to the progression of metabolic syndrome with a potential for significant morbidity. The treatment of OSAS in obese children has not been standardized. Adenotonsillectomy is considered the primary intervention followed by continuous positive airway pressure treatment if OSAS persists. Other methods such as oral appliances, surgery, positional therapy, and weight loss may be beneficial for individual subjects. The present review discusses these issues and suggests an approach to the management of obese children with snoring and possible OSAS.

Abstract
BACKGROUND The obesity epidemic has prompted remarkable changes in the proportion of obese children who are referred for habitual snoring. However, the contribution of obesity to adenotonsillar hypertrophy remains undefined. METHODS In our study, 206 nonobese habitually snoring children with polysomnographically diagnosed obstructive sleep apnea (OSA) were matched for age, gender, ethnicity, and obstructive apnea-hypopnea index (OAHI) to 206 obese children. Size estimates of tonsils and adenoids, and Mallampati class scores were obtained, and allowed for the assessment of potential relationships between anatomic factors and obesity in pediatric OSA. RESULTS The mean OAHI for the two groups was approximately 10.0 episodes/h total sleep time. There was a modest association between adenotonsillar size and OAHI in nonobese children (r = 0.22; p < 0.001) but not in obese children. The mean (+/- SEM) adenotonsillar size was larger in nonobese children (3.85 +/- 0.16 vs 3.01 +/- 0.14, respectively; p < 0.0001), and conversely Mallampati class scores were significantly higher in obese children (p < 0.0001). CONCLUSION The magnitude of adenotonsillar hypertrophy required for any given magnitude of OAHI is more likely to be smaller in obese children compared to nonobese children. Increased Mallampati scores in obese children suggest that soft-tissue changes and potentially fat deposition in the upper airway may play a significant role in the global differences in tonsillar and adenoidal size among obese and nonobese children with OSA.

Abstract
The objective of this study was to assess the effect of weight loss on sleep-disordered breathing (SDB) in obese teenagers attending a residential treatment center. We also assessed whether the presence of SDB at the start of the weight management therapy was correlated with the amount of weight loss achieved. Obese teenagers were recruited and underwent anthropometry and sleep screening. Subjects with SDB (apnea hypopnea index (AHI)>or=2) received a follow-up screening after weight loss therapy. Sixty-one obese subjects were included (age=14.8+/-2.3; BMI z score=2.7+/-0.4). Thirty-one subjects were diagnosed with SDB with 38% continuing to have residual SDB after a median weight loss of 24.0 kg. Subjects with SDB had a higher median relative decrease in BMI z score compared to subjects without SDB which was 30.5, 33.6, and 50.4% in the group with AHI of the baseline screening study<2, 2<or=AHI<5, and AHI>or=5, respectively (P=0.02). AHI of the baseline screening study correlated significantly with the relative decrease in BMI z score (partial r=0.37; P=0.003), controlling for gender, age, initial BMI z score, and time between both studies. In conclusion, weight loss was successful in treating SDB in obese teenagers. In addition, there was a positive association between the severity of SDB at the start of the treatment and the amount of weight loss achieved. These findings are in favor of considering weight loss as a first-line treatment for SDB in obese children and adolescents.

Abstract
STUDY OBJECTIVES The purpose of this study was to describe the prevalence of polysomnographically diagnosed OSAS and to describe the severity of sleep associated gas exchange abnormalities (SAGEA) in habitually snoring children. We hypothesized that there would be a high prevalence of OSAS in obese children with habitual snoring and that the most overweight children would have the most significant SAGEA. DESIGN Retrospective chart review. MEASUREMENTS AND RESULTS Nocturnal polysomnography (NPSG) data from 114 children and adolescents referred for habitual snoring were examined. 74 of the subjects were male (65%), average age of 9.78 +/- 4.19 years, average AHI 13.51 +/- 20.25, mean BMI z-score 1.79 +/- 1.18. BMI z-scores correlated positively with severity of OSAS (P < 0.05) such that children with progressive degrees of obesity had more frequent respiratory events during sleep. Additionally, severity of sleeping hypercapnea as measured by percent of total sleep time with EtCO(2) values above 50 mm Hg was more severe with progressive degrees of obesity. Likewise, all measures of oxyhemoglobin desaturation were more severe with progressive degrees of obesity. Positive correlations between the severity of SAGEA and degree of obesity remained even after controlling for the severity of OSAS. CONCLUSIONS OSAS is highly prevalent in children referred to a pediatric sleep center with complaints of habitual snoring across a wide spectrum of weight categories. SAGEA increases with progressive obesity even when controlling for the severity of OSAS suggesting that obesity is an independent risk factor for SAGEA. Furthermore, because obese children frequently have SAGEA, capnography should be obtained during NPSG when possible.

Abstract
The proportion of children who are overweight or obese has risen steadily in recent decades and approaches a quarter of all children in Western countries. This global epidemic of excess weight and adiposity in humans is associated with increased morbidity and mortality, especially related to diabetes and poor cardiovascular health. It would appear that obesity is also generally accepted to be an important risk factor in the development of sleep disordered breathing (SDB), in children as well as adults. The article, "The prevalence, anatomical correlates and treatment of sleep-disordered breathing in obese children and adolescents", by Verhulst et al., also in this issue, reviews evidence supporting the view that obese children are at higher risk of developing SDB. We believe, however, that the available studies do not support a straightforward association of overweight or obesity with increased prevalence of SDB. Rather, the available data is clearly equivocal mainly due to methodological differences between the previous studies. This review nonetheless examines the factors which may modulate the relationship between overweight or obesity and prevalence of SDB, particularly ethnicity and age.

Abstract
Introduction: The incidence of childhood obesity is rising across the globe, and obesity related co-morbidities are increasing concomitantly in the paediatric population.
Materials and Meth- ods: PubMed search for research and review papers on complications of childhood obesity was performed.
Results: The consequences of childhood obesity can be broadly classified into medical and psychosocial consequences. Medical consequences include metabolic complications such as diabetes mellitus, hypertension, dyslipidaemia and non-alcoholic fatty liver disease, and me- chanical problems such as obstructive sleep apnoea syndrome and orthopaedic disorders. Psychological and social consequences are prevalent but often overlooked. Local data on these complications were also discussed.
Conclusion: Childhood obesity is associated with significant morbidities, which not only have immediate impact on the health of the obese children, but also significantly increase the risk of morbidities in adulthood.
Key words: Medical consequence, Psychosocial consequence

Abstract
PURPOSE OF REVIEW To delineate some of the major morbid phenotypes that have emerged in pediatric obstructive sleep apnea (OSA), address new concepts in our understanding of OSA-associated morbidities, and elaborate on innovative therapeutic schemes that may improve outcomes for this condition. In addition, the conceptual framework whereby a childhood condition such as OSA can be linked to specific adult diseases will be presented. RECENT FINDINGS OSA in children is a frequent condition that affects up to 3% of nonobese, otherwise healthy children. In recent years, increased awareness of OSA and changes in obesity rates in children have contributed to significant changes in disease prevalence and clinical presentation, such that distinct morbidity-related phenotypes have become apparent. Furthermore, oxidative stress and systemic inflammatory pathways are mechanistically involved in the pathophysiology of OSA-associated morbidity. Adenotonsillectomy, the treatment of choice for pediatric OSA, may not be as efficacious as previously thought. Alternative nonsurgical therapies have started to emerge and may become an essential component of treatment. SUMMARY Pediatric OSA, particularly when obesity is concurrently present, is associated with substantial end-organ morbidities that primarily but not exclusively affect central nervous and cardiovascular systems. These morbidities are pathophysiologically mediated by inflammatory and free radical mediators. Although adenotonsillectomy remains the first line of treatment, more critical assessment of its role is needed, and incorporation of nonsurgical approaches to pediatric OSA seems warranted.

Abstract
The clinical relevance of the term "metabolic syndrome", the definition criteria, and predictive power are being disputed. Inclusion of sleep-disordered breathing and sleep apnoea into a definition of metabolic syndrome is also controversial once children and/or adolescents are affected. Nevertheless, along with the increasing prevalence of childhood obesity, the prevalence of the metabolic syndrome in obese children is reported at 30%, irrespective of the definition applied. Moreover, childhood obesity is associated with sleep-disordered breathing. Adipocytokines, cytokines secreted from adipose tissue, are thought to play a major role in the pathophysiology of metabolic syndrome. Leptin was initially suggested as a promising "anti-obesity" hormone. New concepts indicate that in humans leptin and its soluble receptor may be more important in states of energy deficiency rather than a predictor of the metabolic syndrome. Adiponectin, on the other hand, is not only related to obesity and insulin resistance, but appears to be the strongest predictor for metabolic syndrome, even in children. In newborns and infants, both adipocytokines occur in high concentrations, even though this cannot completely explain the increased risk for ensuing metabolic disease later in life. Finally, low-grade systemic inflammation may underlie the clustering of metabolic risk factors. Overall factors from the adipose tissue may constitute not only markers but also mediators of metabolic sequelae of obesity.

Abstract
Introduction: Obesity affects about 10% to 15% of our school-going population in Singapore and is a risk factor for development of obstructive sleep apnoea hypopnoea syndrome (OSAHS). This article reviews the prevalence, aetiology, pathophysiology, diagnosis, complications and treatment of obese children with OSAHS with particular reference to children in Singapore.
Methods: Review of articles or conference papers reporting data with regards to OSAHS in Singapore children.
Results: Prevalence of OSAHS was high in obese children in Singapore and was more common in males with no racial predisposition. Hypersomnolence as a presenting symptom was uncommon. Cognitive function, behaviour, attention and processing speed was affected and improved after intervention. Abnormalities of glucose metabolism were also found with the respiratory disturbance index (RDI) as an independent predictor of insulin resistance. Tonsillectomy and or adenoidectomy was efficacious as treatment and risk of complications was low. No significant increase in weight occurred post intervention in those enrolled in concurrent weight management programmes.
Conclusions: Prevalence of OSAHS is high in obese Singapore children and many are ‘asymptomatic’. A low threshold for evaluation is necessary for early diagnosis and intervention for prevention of morbidity. Tonsillectomy and/or adenoidectomy is safe and efficacious and remains the first-line treatment in most obese patients.

Abstract
BACKGROUND The relative importance of obesity and adenotonsillar hypertrophy in the pathogenesis of obstructive sleep-disordered breathing (SDB) in childhood is unclear. Adenotonsillectomy (AT) for SDB is not always curative, and obese children are at increased risk for residual disease postoperatively. OBJECTIVE The aim of this investigation was to assess the efficacy of AT as treatment for SDB in obese and nonobese children. METHODS Children with adenoidal and/or tonsillar hypertrophy who underwent AT for the treatment of SDB underwent polysomnography preoperatively and postoperatively. A body mass index (BMI) z score of > 1.645 was used to define obesity. The achievement of a postoperative obstructive apnea-hypopnea index (OAHI) of less than one episode per hour (ie, the cure of SDB) was the primary outcome measure. RESULTS Twenty-two obese children (mean [+/- SD] age, 5.8 +/- 1.8 years; mean BMI z score, 2.6 +/- 0.8; mean OAHI, 9.5 +/- 9.7 episodes per hour) and 48 nonobese children (mean age, 6.9 +/- 2.6 years; mean BMI z score, 0.09 +/- 1.1; OAHI, 6 +/- 5.4 episodes per hour) were recruited. After surgery, obese and nonobese subjects did not differ in the efficacy of AT (postoperative OAHI of less than one episode per hour, 22.7% vs 25% of subjects, respectively; p > 0.05). The presence of obesity, adenoidal or tonsillar hypertrophy, gender, and postoperative BMI change were not significant predictors of SDB cure. CONCLUSIONS Obesity does not necessarily predict an unfavorable outcome of AT as treatment for SDB.

Abstract
BACKGROUND The UK government has recommended the development of obesity services for children. As obesity is common, studying every obese child for obstructive sleep apnoea (OSA) would be challenging and full paediatric sleep services are not available in every area in Europe. The purpose of this study was to consider how well clinical features predict significant OSA in obese children in order to help prioritise the need for sleep studies and subsequent treatment. METHODS Consecutive children referred for obesity management aged 2-16 years with a body mass index (BMI) of >2.5 z scores for age were offered a sleep study using overnight oximetry and audiovisual recordings. Significant OSA was defined as > or = 5 dips/h of >4% oxygen saturation or > or = 5 respiratory-event related arousals/h. RESULTS Forty-one of 158 (26%) children (mean BMI z score 3.7) had significant OSA and 95% of these had either reported apnoea, restless sleep or tonsillar hypertrophy (TH). Nineteen percent of all children had none of these features. BMI was not related to OSA. CONCLUSION If only obese children with reported apnoea, restless sleep or TH have a sleep study, 95% of all obese children with significant OSA will be identified using this method.

Abstract
BACKGROUND Obesity is a highly prevalent chronic problem with health and fiscal consequences. Data from adults and nonsurgical pediatric patients suggest that obesity has serious implications for the US economy. OBJECTIVE Our goal was to describe the impact of BMI on hospital charges in children undergoing adenotonsillectomy (AT). METHODS AND PROCEDURES We carried out a retrospective comparative analysis of the electronic anesthesia record and the charges from billing data from a large tertiary institution on children aged 3-18 years who had AT during the year 2005-2007. The main outcome measures were mean total hospital charges, likelihood of admission, and length of hospital stay (LOS). RESULTS Of 1,643 children, 68.9% were aged <10 years, 76% were whites, and 74.1% had private commercial insurance. Most (75.3%) children were discharged on the day of surgery. Obese and overweight children were more likely to be admitted than their normal-weight peers (X(2)=26.3, P<0.001). Among those admitted, BMI showed a positive correlation with LOS (r=0.20, P<0.001). Obese and overweight patients had significantly higher total hospital charges than their healthy-weight counterparts (P=0.001). Anesthesia, postanesthesia care unit (PACU), and pharmacy and laboratory charges were also higher for obese than normal-weight children (P<0.05). DISCUSSION Overweight and obese children undergoing AT accrued higher hospital charges and had longer postoperative LOS than their healthy-weight peers. If these findings are extendable to other surgical procedures, they could have far-reaching implications for the US economy.

Abstract
Pediatric obesity is increasing worldwide and disproportionately affects the economically and socially disadvantaged. Obese children are at risk of developing the (dys)metabolic syndrome, insulin resistance, early-onset type 2 diabetes mellitus, polycystic ovarian syndrome, hypertension, hyperlipidemia, and obstructive sleep apnoea. Those with diabetes may have mixed features of type 1 and type 2 diabetes mellitus. Pediatric obesity is the result of persistent adverse changes in food intake, lifestyle, and energy expenditure. It may be because of underlying a genetic syndrome or a conduct disorder. Children living in urban settings often lack safe, affordable, and accessible recreational facilities. Tight educational schedules mean less free time, while computer games and television have become preferred recreational activities. More families are eating out or eating take-out meals and processed foods at home because of pressures of work and time constraints. Consumer advertising targeted at children and the ready availability of vending machines encourage unwise food choices. Some children eat excessively because they are depressed, anxious, sad, or lonely. Often families and obese children are aware of the need for healthy eating and exercise but are unable to translate knowledge into weight loss. Population-based measures such as public education, school meal reforms, child-safe exercise friendly environments, and school-based and community-based exercise programs have been shown to be successful to varying degrees, but there remain individuals who will need special help to overcome obesity. Overeating (e.g. binge eating) may be a manifestation of disordered coping behavior but may also be because of defects in the neural and hormonal control of appetite and satiety. New pharmacological approaches are targeting these areas. We need a coordinated approach involving government, communities, and healthcare providers to provide a continuum of population-based interventions, focused screening, and personalized multidisciplinary interventions for the obese child and family.

Abstract
The spectrum of sleep disordered breathing (SDB) encompasses habitual snoring at the low end of severity all the way to frank obstructive sleep apnea (OSA), with upper airway resistance syndrome (UARS) and obstructive alveolar hypoventilation being considered as less severe variants of this condition. SDB occurs in children of all ages, from neonates to adolescents, and is characterized by repeated events of increased upper airway resistance as well as with either partial or complete upper airway obstruction during sleep, all of which may result in disruption of normal gas exchange and sleep integrity [1]. SDB was initially described over a century ago [2] and was then rediscovered in children by Guilleminault in 1976 [3]. However, this complex and relatively prevalent disorder is only now being recognized as a major public health problem. During the initial years since the seminal paper by Guilleminault et al [3], it became apparent that the classic clinical syndrome of OSA in children markedly differed from the OSA seen in adults, in particular with respect to gender distribution, clinical manifestations, polysomnographic findings, and treatment approaches [4,5]. However in more recent years, the epidemic of obesity that affects the pediatric population all over the world has led, in our opinion, to the emergence of a phenotypic variant of OSA in children that closely resembles that of adults with the disease. In this paper, we will review the pathophysiological mechanisms of OSA in children, delineate the clinical manifestations associated with the disease, and provide arguments for our novel and hopefully useful proposition that aims to define 2 types of OSA in children. For the sake of convenience, and in analogy with type I and type II diabetes, we propose to divide pediatric OSA as types I and II.
