RESUMEN
OBJECTIVE: To evaluate the associations of OSA severity, snoring symptoms, subjective sleep quality, and daytime sleepiness with executive functioning and behaviors in children with obesity. METHODS: This was a cross-sectional study of children aged 8-18 years with obesity and symptoms suggestive of OSA. All participants underwent an overnight polysomnography and completed a set of questionnaires to assess their sleep-related breathing disordered (SRBD) symptoms [Pediatric Sleep Questionnaire (SRBD-PSQ)], sleep quality [Pittsburgh Sleep Quality Index (PSQI)], executive function [Behavior Rating Inventory of Executive Function (BRIEF)], and inattention and hyperactivity symptoms (Conners-3 Parent Short Form). RESULTS: A total of 85 children (62% male, mean age: 13.9 ± 3.0 years) were included in this analysis, of whom 36, 16, and 33 were categorized into the non-OSA (obstructive apnea hypopnea index, OAHI < 1.5/h), mild OSA (OAHI 1.5-5/h), and moderate-severe OSA (OAHI ≥ 5/h) groups, respectively. Of 85 participants, 27 (32%) were classified with poor sleep quality (PSQI composite score ≥ 8). From multiple linear regression analyses, poor sleep quality and sleepiness were both independently associated with higher BRIEF behavioral regulation T-score, metacognition T-score, and global executive composite T-score in the fully adjusted model. In addition, poor sleep quality was also independently associated with higher Conners-3 inattention and executive functioning T-scores, while greater sleepiness was also associated with a higher learning problem T-score. The presence of OSA and snoring were not associated with any cognitive outcomes. CONCLUSIONS: Subjective sleep quality and daytime sleepiness, but not OSA severity and snoring symptoms, were independently associated with executive functioning and behavioral problems in children with obesity.

PURPOSE: This study evaluated screening tasks able to identify children with medical conditions or disabilities who may benefit from physical literacy. METHOD: Children completed ≤20 screening tasks during their clinic visit and then the Canadian Assessment of Physical Literacy (2nd edition) at a separate visit. Total Canadian Assessment of Physical Literacy scores <30th percentile were categorized as potentially needing physical literacy support. Receiver operator characteristic curves identified assessment cut points with 80% sensitivity and 40% specificity relative to total physical literacy scores. RESULTS: 223 children (97 girls; 10.1 [2.6] y) participated. Physical activity adequacy, predilection, and physical competence achieved ≥80% sensitivity and ≥40% specificity in both data sets. Adequacy ≤ 6.5 had 86% to 100% sensitivity and 48% to 49% specificity. Daily screen time >4.9 hours combined with Adequacy ≤6.15 had 88% to 10% sensitivity and 53% to 56% specificity. CONCLUSIONS: Activity adequacy, alone or with screen time, most effectively identified children likely to benefit from physical literacy support. Adequacy and screen time questionnaires are suitable for clinical use. Similar results regardless of diagnosis suggest physical competence deficits are not primary determinants of active lifestyles. Research to enhance screening specificity is required.
RESUMEN
BACKGROUND: Physical literacy is a concept used to describe the combined physical, affective and cognitive capacities facilitating an active lifestyle. Physical activity participation is essential for children living with chronic medical conditions, but knowledge of physical literacy among this group is scarce. METHODS: An explanatory, sequential mixed methods design was used to comprehensively describe the physical literacies of children with chronic medical conditions (CMCs). Participants were recruited from paediatric cardiology, respirology/cystic fibrosis, neurology, haematology and endocrinology outpatient clinics. All participants completed the Canadian Assessment of Physical Literacy (2nd Edition), and those with higher and lower scores were invited to a semi-structured interview. A deductive-inductive thematic analysis was applied using Margaret Whitehead's conceptualization of physical literacy. RESULTS: Using normative strata, 80.0% of the 99 children assessed (mean age = 9.97 ± 1.3 years, 48% girls) were considered beginning or progressing in their overall physical literacy (mean score = 56.5 ± 13.8/100). Meanwhile, physical literacy informed participants' approach to new, active experiences and may have contributed to a strong sense of self. There was a significant difference between endocrinology and haematology patients on total physical literacy score (p = 0.03) but not domain scores. Participants scored high on motivation/confidence (mean = 22.9 ± 5.0/30) but obtained low physical competence (mean = 11.8 ± 5.6/30) and daily behaviour scores (n = 72, mean = 15.5 ± 7.1/30). Main themes represent salient experiences of children with CMCs within the domains of physical literacy, including their need to evaluate active contexts, self-regulate activity intensity and manage physical limitations. CONCLUSIONS: Children with CMCs can achieve recommended levels of physical literacy without meeting normative standards for physical competence. Participants would benefit from a physical literacy intervention that targets the development of bodily self-regulation skills and risk evaluation in active settings.

Objectives: The COVID-19 pandemic has impacted mental health at a population level. Families of children with health vulnerabilities have been disproportionately affected by pandemic-related policies and service disruptions as they substantially rely on the health and social care system. We elicited the impact of the COVID-19 pandemic on children with health and disability-related vulnerabilities, their families, and their health care providers (HCPs). Methods: Children with diverse health vulnerabilities (cardiac transplantation, respiratory conditions, sickle cell disease, autism spectrum disorder, mental health issues, and nearing the end of life due to a range of underlying causes), as well as their parents and HCPs, participated in semi-structured interviews. Data were analyzed using qualitative content analysis in determining themes related to impact and recommendations for practice improvement. Results: A total of 262 participants (30 children, 76 parents, 156 HCPs) were interviewed. Children described loneliness and isolation; parents described feeling burnt out; and HCPs described strain and a sense of moral distress. Themes reflected mental health impacts on children, families, and HCPs, with insufficient resources to support mental health; organizational and policy influences that shaped service delivery; and recommendations to enhance service delivery. Conclusion: Children with health vulnerabilities, their families and HCPs incurred profound mental health impacts due to pandemic-imposed public health restrictions and care shifts. Recommendations include the development and application of targeted pandemic information and mental health supports. These findings amplify the need for capacity building, including proactive strategies and mitigative planning in the event of a future pandemic.
RESUMEN
PURPOSE OF REVIEW: Myotonic dystrophy type 1 (DM1) is a severe, progressive genetic disease that affects approximately 1 in 2,500 individuals globally [Ashizawa et al.: Neurol Clin Pract 2018;8(6):507-20]. In patients with DM1, respiratory muscle weakness frequently evolves, leading to respiratory failure as the main cause of death in this patient population, followed by cardiac complications [de Die-Smulders et al.: Brain 1998;121(Pt 8):1557-63], [Mathieu et al.: Neurology 1999;52(8):1658-62], [Groh et al.: Muscle Nerve 2011;43(5):648-51]. This paper provides a more detailed outline on the diagnostic and management protocols, which can guide pulmonologists who may not have experience with DM1 or who are not part of a neuromuscular multidisciplinary clinic. A group of neuromuscular experts in DM1 including pulmonologists, respiratory physiotherapists and sleep specialists discussed respiratory testing and management at baseline and during follow-up visits, based on their clinical experience with patients with DM1. The details are presented in this report. RECENT FINDINGS: Myotonic recruited 66 international clinicians experienced in the treatment of people living with DM1 to develop and publish consensus-based care recommendations targeting all body systems affected by this disease [Ashizawa et al.: Neurol Clin Pract. 2018;8(6):507-20]. Myotonic then worked with 12 international respiratory therapists, pulmonologists and neurologists with long-standing experience in DM respiratory care to develop consensus-based care recommendations for pulmonologists using a methodology called the Single Text Procedure. This process generated a 7-page document that provides detailed respiratory care recommendations for the management of patients living with DM1. This consensus is completely based on expert opinion and not backed up by empirical evidence due to limited clinical care data available for respiratory care management in DM patients. Nevertheless, we believe it is of relevance for professionals treating adults with myotonic dystrophy because it addresses practical issues related to respiratory management and care, which have been adapted to meet the specific issues in patients with DM1. SUMMARY: The resulting recommendations are intended to improve respiratory care for the most vulnerable of DM1 patients and lower the risk of untoward respiratory complications and mortality by providing pulmonologist who are less experienced with DM1 with practical indications on which tests and when to perform them, adapting the general respiratory knowledge to specific issues related to this multiorgan disease.

BACKGROUND: Children with chronic kidney disease (CKD) are at risk for obstructive sleep apnea (OSA) and hypertension. The objectives of this study were to explore associations between OSA severity using the apnea-hypopnea-index(AHI) and obstructive apnea-hypopnea-index(OAHI) on polysomnography (PSG), OSA symptoms, and measures of hypertension in children with CKD. METHODS: One-night in-laboratory PSGs and 24-h ambulatory blood pressure monitoring (ABPM) were performed on children with CKD stages 2-5 (non-dialysis dependent). Sleep questionnaires, including the modified Epworth Sleepiness Scale (ESS) and the Pediatric Sleep Questionnaire (PSQ), were administered during the sleep study. RESULTS: Nineteen children and adolescents completed a PSG and questionnaires and thirteen completed ABPMs. Mean (standard deviation) age at the time of the sleep study was 14.1 (3.2) years. Eleven (58%) participants had CKD stage two, and eight (42%) had stage 3-4. None of the participants were found to have OSA on PSG. One participant had a positive ESS score (≥ 11) and five participants had positive PSQ scores (≥ eight). Night systolic and diastolic pressures were strongly correlated with the OAHI (r = 0.67 and r = 0.69, respectively, p < 0.05), while the AHI was not correlated with any blood pressure measures. CONCLUSIONS: Our study did not find OSA on PSG in children with predominantly mild to moderate CKD. The OAHI was found to be strongly correlated with nighttime blood pressures. Future prospective studies with a larger sample size are needed to monitor for potential progression of symptoms and findings on PSG in pediatric patients as they evolve across the spectrum of CKD.

Bronchopulmonary dysplasia, the most common pulmonary complication of extremely preterm (EPT) birth, has longstanding multiorgan repercussions, with increasing reports of emphysema and cardiac disease in early adulthood. There are currently no clear recommendations pertaining to best practices for optimal multidisciplinary cardiorespiratory follow-up of EPT children. We report the outcomes of a 2-day consensus workshop involving a Canadian panel of 31 multidisciplinary experts with the goal of improvement and standardization of the cardiopulmonary follow-up care of EPT infants (i.e., born at <28 weeks' gestation), from neonatal discharge to mid childhood. The most relevant and important clinical outcomes to evaluate were identified. Practical aspects of integrating cardiopulmonary follow-up into ambulatory care clinics were explored. This article summarizes the discussions from this workshop and provides the panel's recommendations for clinical follow-up and research priorities.
RESUMEN
BACKGROUND: Sleep-disordered breathing (SDB) is prevalent in children and is associated with significant comorbidity. OBJECTIVES: To describe paediatric sleep physician and diagnostic testing resources for SDB in Canadian children. METHODS: A 38-item, Internet-based survey was sent to the 32 members of the Canadian Pediatric Sleep Network (CPSN). A shorter telephone survey was administered to all 182 non-CPSN sleep laboratories across Canada. RESULTS: Responses were obtained from 29 of 31 (91%) CPSN members and 121 of 182 (66%) non-CPSN sleep facilities. Sixty-seven of 121 (55%) of the responding non-CPSN facilities reported that they see children <18 years of age. Thirty-six of 121 (30%) and 23 of 121 (19%), respectively, see children ≤12 years of age or ≤8 years of age. Marked disparities across provinces/territories were observed, with no practitioners or polysomnography in the Yukon, Northwest Territories, Nunavut, Saskatchewan, New Brunswick, Prince Edward Island, and Newfoundland and Labrador. Alberta has the smallest ratio of children to practitioners (approximately 167,000 to 1) and Ontario has the smallest ratio of children to polysomnograms performed per year (approximately 487,000 to 1). Reported wait times for polysomnography ranged from <1 month, to 1.5 to 2 years. In paediatric tertiary care centres, the number of polysomnograms performed per year ranged from 55 to 700 (median 480) and in other laboratories the range was 400 to 4000 (median 1100). CONCLUSIONS: The present study demonstrates a significant lack of resources and services for paediatric SDB care across Canada, with pronounced geographical disparities. Even if only affected children were tested with polysomnography, the authors estimate there are 7.5 times more children with SDB than current testing capacity.
HISTORIQUE: Les troubles respiratoires du sommeil (TRS) sont prévalents chez les enfants et s'associent à une comorbidité importante. OBJECTIFS: Décrire les spécialistes du sommeil en pédiatrie et les tests pour diagnostiquer les TRS chez les enfants canadiens. MÉTHODOLOGIE: Les 32 membres du Canadian Pediatric Sleep Network (CPSN) ont répondu à un sondage virtuel de 38 questions. Les 182 laboratoires du sommeil du Canada ne faisant pas partie du CPSN ont répondu à un sondage téléphonique plus court. RÉSULTATS: Vingt-neuf des 31 membres du CPSN (91 %) et 121 des 182 laboratoires du sommeil non membres du CPSN (66 %) ont répondu. Soixante-sept des 121 établissements répondants ne faisant pas partie du CPSN (55 %) ont déclaré voir des enfants de moins de 18 ans. Trente-six (30 %) et 23 (19 %) de ces 121 établissements, respectivement, voient des enfants de 12 ans ou moins et de huit ans ou moins. Les chercheurs ont observé des disparités marquées entre les provinces et les territoires. Ainsi, il n'y a pas de praticiens ou de polysomnogrammes au Yukon, dans les Territoires du Nord-Ouest, au Nunavut, en Saskatchewan, au Nouveau-Brunswick, à l'Île-du-Prince-Édouard et à Terre-Neuve-et-Labrador. L'Alberta présente le plus petit ratio entre les enfants et les praticiens (environ 167 000 pour 1) et l'Ontario, le plus petit ratio entre les enfants et les polysomnographies effectuées par année (environ 487 000 pour 1). Les temps d'attente déclarés pour subir une polysomnographie variaient entre moins d'un mois et 1,5 à deux ans. Dans les centres pédiatriques de soins tertiaires, le nombre de polysomnographies effectuées par année variait entre 55 et 700 (médiane de 480), tandis que dans les autres laboratoires, il oscillait entre 400 et 4 000 (médiane de 1 100). CONCLUSIONS: La présente étude démontre un manque flagrant de ressources et de services pour les soins des TRS en pédiatrie au Canada, ainsi que des écarts géographiques marqués. Même si seuls les enfants touchés ont subi une polysomnographie, les auteurs estiment qu'il y a 7,5 fois plus d'enfants ayant des TRS que la capacité actuelle de les évaluer.
RESUMEN
The COVID-19 pandemic imposed widespread impacts on the health and well-being of children with respiratory challenges and their families, as well as on the health care system that supports them. An exploratory qualitative study was undertaken to examine how the pandemic impacted families' and health care providers' daily lives and experiences of care. Four youth, 12 parents and 7 health care providers participated in interviews via telephone or online technology. Content analysis of transcribed interviews revealed participant experiences, including initial responses to the pandemic, adjustment to pandemic shifts, and anticipation of the future. While deleterious physical health impacts were minimal for children with pre-existing respiratory conditions, their mental health was negatively impacted by the pandemic and related health protocols. Families and health care providers experienced strain, yet demonstrated resilience. Pandemic-related shifts profoundly impacted daily life at home, school, and work. Pediatric pandemic planning in clinical care is recommended to better address the needs of children with respiratory conditions and their families as well as pediatric health care providers.

RATIONALE: Home mechanical ventilation (HMV) is an advanced medical therapy offered to children with medical complexity. Despite the growing pediatric HMV population in North America, there are limited studies describing healthcare utilization and predictors of highest costs using robust health administrative data. OBJECTIVES: To describe patterns of healthcare utilization and costs in children receiving HMV over a 14-year period in Ontario, Canada. METHODS: We conducted a retrospective population-based cohort study (April 1, 2003 to March 31, 2017) of children aged 0-18 years receiving HMV via invasive mechanical ventilation (IMV) or non-invasive ventilation (NIV). Paired t-tests compared healthcare system utilization and costs two years before and two years after HMV approval. We developed linear models to analyze variables associated with children in the top quartile of health service utilization and costs. RESULTS: We identified 835 children receiving HMV. In the two years after HMV approval compared to the 2 years prior, children had decreased hospitalization days (median 9 (IQR 3-30) versus 29 (6-99), p<0.0001) and ICU admission days (6.6 (1.9-18.0) versus 17.1 (3.3-70.9), p<0.0001) but had increased homecare service approvals (195 (24-522) versus 40 (12-225), p<0.0001) and outpatient Pulmonology visits (3 (1-4) versus 2 (1-3), p<0.0001). Total healthcare costs were higher in the two years after HMV approval (mean $164,892 (SD $214,187) versus $128,941 ($194,199), p<0.0001). However, all-cause hospital admission costs were reduced ($66,546 ($142,401) versus $81,578 ($164,672), p<0.0001). Highest total 2-year costs were associated with IMV (OR 3.45, 95% CI 2.24-5.31; reference NIV), number of medical devices at home (OR 1.63, 95% CI 1.35-1.96; reference no technology), and increased healthcare costs in the year prior to HMV initiation (OR 2.23, 95% CI 1.84-2.69). CONCLUSIONS: Children progressing to the need for HMV represent a worsening in their respiratory status that will undoubtedly increase healthcare utilization and costs. We found that the initiation of HMV in these children can reduce inpatient healthcare utilization and costs but can still increase overall healthcare expenditures, especially in the outpatient setting.
RESUMEN
RATIONALE: Information is limited about the association between obstructive sleep apnea (OSA) and mental disorders in children. OBJECTIVES: In children, (1) to evaluate the association between OSA and new mental healthcare encounters; (2) to compare mental healthcare encounters two years post- to pre-OSA treatment initiation. METHODS: We conducted a retrospective longitudinal cohort study using Ontario health administrative data (Canada). Children (0-18 years) who underwent diagnostic polysomnography (PSG) 2009-2016 and met criteria for definition of moderate-severe OSA (PSG-OSA) were propensity score weighted by baseline characteristics and compared to children who underwent a PSG in the same period but did not meet the OSA definition (PSG-No-OSA). Children were followed until March 2021. Weighted cause-specific Cox Proportional Hazards and Modified Poisson regression models were used to compare time from PSG to first mental healthcare encounter and frequency of new mental healthcare encounters per person time, respectively. Among those who underwent adenotonsillectomy (AT) or were prescribed and claimed positive airway pressure therapy (PAP), we used age-adjusted conditional logistic regression models to compare two years post- to pre-treatment odds of mental healthcare encounters. RESULTS: Of 32,791 children analyzed, 7,724 (23.6%) children met criteria for moderate-severe OSA. In PSG-OSA group, 7,080 (91.7%) were treated (AT or PAP). Compared to PSG-No-OSA, the PSG-OSA group had a shorter time from PSG to first mental healthcare encounter (HR: 1.08; 95%CI: 1.05-1.12), but less frequent mental healthcare encounters in follow-up (RR: 0.92; 95% CI: 0.87-0.97). OSA treatment (AT or PAP) was associated with lower odds of mental healthcare encounters two years post-treatment initiation compared to two years prior (OR: 0.69; 95% CI: 0.65-0.74). CONCLUSION: In this large population-based study of children who underwent PSG for sleep disorder assessment, OSA diagnosis/treatment was associated with an improvement in some mental health indicators, such as fewer new mental healthcare encounters compared to no OSA, and lower odds of mental healthcare encounters compared to pre-OSA treatment.
RESUMEN
STUDY OBJECTIVES: The association between obstructive sleep apnea (OSA) and lifestyle habits in children with obesity is largely unknown. This study aimed to determine whether there was an association between lifestyle patterns (sleep quality, physical activity, recreational screen time, and substance use) and OSA presence and severity in children with obesity. METHODS: This cross-sectional study recruited children with obesity, aged 8-17 years, who were referred to undergo polysomnography. Children completed questionnaires on sleep quality, physical activity, recreational screen time, and substance use. Children also had a diagnostic polysomnography. The association between questionnaire scores and OSA severity, after adjusting for body mass index z-score, age, and sex, was evaluated using negative binomial multiple regression. Correlations were conducted between sleep quality, physical activity, screen time, substance use, and OSA severity. RESULTS: A total of 100 children were included in the analysis (mean age: 14.3 ± 2.6 years; 44% female; mean body mass index z-score: 2.5 ± 0.4; 65% with OSA). In the adjusted regression analysis, each additional substance-use behavior was associated with a 17% (95% confidence interval: 1%, 36%) increase in OSA severity. Correlations were identified between poorer sleep quality and lower physical activity (r = -.42), poorer sleep quality and more substance-use behaviors (r = .40), and greater physical activity and less substance-use behaviors (r = -.26). CONCLUSIONS: In children with obesity, more substance-use behaviors were independently associated with greater OSA severity. As there are complex, bidirectional relationships between lifestyle behaviors and OSA severity, interventions need to be comprehensive and multifactorial to ensure successful treatment of OSA and its sequelae in children.

Chronic respiratory failure is a common endpoint in the loss of respiratory muscle function in patients with progressive neuromuscular disease (NMD). Identifying the onset of hypoventilation is critical to allow for the timely introduction of ventilator support and effectively manage respiratory failure [1-3]. While there are accepted criteria governing the diagnosis of hypoventilation during polysomnography (PSG) [4], there is concern that criteria are insufficient for identifying hypoventilation in the earlier stages of respiratory insufficiency related to NMD. The purpose of this project was to identify more sensitive criteria for identifying hypoventilation. METHODS: Fifteen pediatric pulmonologists with broad experience in managing patients with NMD, 10 of whom were board certified in and practice sleep medicine, were assembled and performed a review of the pertinent literature and a two-round Delphi process with 6 domains (Table 1). RESULTS: Within the 6 domains there were three pertinent items per domain (Table 2). There was clear agreement on findings on history (morning headaches) and pulmonary function testing (FVC <â50% or awake TcCO2 >â45âmmHg) indicating a high concern for nocturnal hypoventilation. There was close agreement on the definitions for nocturnal hypercapnia and hypoxemia. PSG criteria were identified that indicate a patient is likely in the transitional phase from adequate ventilation to hypoventilation. DISCUSSION: We identified a set of clinical criteria that may allow for more sensitive diagnosis of hypoventilation in NMD and earlier initiation of non-invasive ventilation leading to a reduction in the respiratory morbidity in progressive NMD. These criteria need to be further and more broadly validated prospectively to confirm their utility.

OBJECTIVES: The incidence, as well as the predictors of mortality, for children receiving home mechanical ventilation (HMV) using population-based data in Canada is a current knowledge gap. Our objectives were to describe HMV incidence and mortality rates, and associations of demographic and clinical variables on mortality. METHODS: Using Ontario health and demographic administrative databases, we conducted a retrospective cohort study (April 1, 2003-March 31, 2017) of children aged 0 to 17 years receiving HMV via invasive mechanical ventilation and noninvasive ventilation. We identified children with complex chronic conditions. We used data from Census Canada to calculate incidence rates and Cox proportional hazards modeling to assess for predictors of mortality. RESULTS: We identified 906 children with a mean (SD) crude incidence rate of 2.4 (0.6) per 100 000 for pediatric HMV approvals that increased by 37% over the 14-year study period. Compared with children who were invasively ventilated, we found mortality was associated with noninvasive ventilation (adjusted hazard ratio [aHR], 1.9; 95% confidence interval [CI], 1.3-2.8). Mortality was highest in children from families in the lowest income quintile (aHR, 2.5; 95% CI, 1.5-4.0), those with neurologic impairment complex chronic conditions (aHR, 2.9; 95% CI, 1.4-6.4), those aged 11 to 17 years at HMV initiation (aHR, 1.5; 95% CI, 1.1-2.0), and those with higher health care costs in the 1 year before HMV initiation (aHR, 1.5; 95% CI, 1.3-1.7). CONCLUSIONS: The incidence of children receiving HMV increased substantially over the 14-year period. Demographic variables associated with increased mortality were identified, suggesting areas requiring greater attention for care providers.

STUDY OBJECTIVES: Obstructive sleep apnea (OSA) and poor sleep quality are highly prevalent in children with obesity, but their individual associations with health-related quality of life (HRQOL) are unknown in this population. The primary objective was to describe the independent association of OSA and sleep quality with HRQOL in children with obesity. METHODS: This was a cross-sectional study of children with obesity at 2 tertiary care centers. Sleep quality and HRQOL were measured with the Pittsburgh Sleep Quality Index and Pediatric Quality of Life Inventory questionnaires, respectively. Multivariable regression models were created to evaluate associations between OSA and sleep quality with HRQOL. RESULTS: There were 98 children (median age 15.0 years, median body mass index z-score 3.8, 44% females). Among the study population, 49/98 (50%) children reported poor sleep quality, 41/98 (42%) children had OSA, and 52/98 (53%) children reported impaired HRQOL. Self-reported poor sleep quality was independently associated with reduced HRQOL, whereas the presence of OSA was not. Children with poor sleep quality had a reduced Pediatric Quality of Life Inventory score by 8.8 compared to children with good sleep quality (95% confidence interval, 2.6-14.9; P = .006), when adjusting for age, sex, body mass index z-score, attention-deficit/hyperactivity disorder, mood/anxiety disorder, and study site. CONCLUSIONS: In the current study of children with obesity, we found that HRQOL was more strongly associated with the self-reported experience of sleep than the presence of OSA. Clinicians should assess and optimize sleep quality as part of the evaluation for OSA in children with obesity. CITATION: Xiao L, Voutsas G, Ryan CM, Katz SL, Narang I.

OBJECTIVE: Limited data regarding sex-based differences in the presentation and phenotype of obstructive sleep apnea (OSA) exists among children with obesity. The study objectives were to compare reported symptoms and polysomnogram (PSG) findings between children with obesity 1) with and without OSA and 2) males and females with OSA. PATIENTS/METHODS: This cross-sectional study included children with obesity, aged 8-18 years, with a diagnostic PSG between 2015 and 2021, referred for evaluating sleep-related breathing. Patient demographics, anthropometrics, and PSG data were recorded. Symptoms were evaluated using Epworth Sleepiness Scale and Pediatric Sleep Questionnaire. Pubertal staging was collected using Tanner Stage questionnaire. PSG parameters, symptoms and pubertal stage were compared between sexes with and without OSA. RESULTS: Of 148 children, 61 (41%) had OSA. Within the OSA group, 41/62 (69%) were male (p = 0.002). Males with OSA reported higher Pediatric Sleep Questionnaire scores compared to males without OSA (0.38 ± 0.2 vs 0.23 ± 0.1; p = 0.002). Males with OSA reported more trouble breathing (p = 0.04) and mouth breathing (p = 0.008) compared to females with OSA. Females with OSA showed longer sleep onset latency (45.8 ± 40.6 min vs 22.4 ± 26.7; p = 0.02) and higher supine obstructive-apnea hypopnea index (32.9 ± 31.1 vs 20.4 ± 18.4 events/hour; p = 0.02) compared to males with OSA. A significant interaction was found between male sex and waist-to-height ratio (ß = 15.34, R2 = 0.18, p = 0.05). CONCLUSIONS: Sex differences in symptoms and phenotype of OSA exist among children with obesity. Such information is beneficial for early diagnosis and management to mitigate adverse outcomes and comorbidities.

STUDY OBJECTIVES: To determine if polysomnographic cardiorespiratory outcomes are associated with and could have the potential to predict the presence of postoperative adverse respiratory events in children with neuromuscular disease undergoing any surgical procedure. METHODS: A retrospective cohort study was conducted at a tertiary pediatric institution. The study population included individuals with neuromuscular disease admitted for a surgical intervention under general anesthetic who had undergone a polysomnogram within 1 year before surgical intervention. Polysomnographic indices and postoperative adverse respiratory events were collected through chart review. Multivariable logistic regression was used to model postoperative adverse respiratory events, where PSG results were considered primary predictors. RESULTS: Postoperative adverse respiratory events occurred in 25/61 (41%) of individuals and consisted mainly of desaturations requiring intervention 33 (73%), airway obstruction 15 (33%), and atelectasis (22%). Results from the unadjusted and adjusted logistic regression models indicated that saturation nadir and bulbar dysfunction individually were independent risk factors for postoperative adverse respiratory events with the highest areas under the receiver operating characteristic curve. A multivariable prediction model using these 2 risk factors provided an area under the receiver operating characteristic curve of 0.74 (95% confidence interval, 0.65-0.83). CONCLUSIONS: Knowing that nocturnal oxygen saturation nadir and the presence of bulbar dysfunction are potential predictors of postoperative adverse respiratory events is useful for future counseling of families and surgical planning, in an effort to improve perioperative management and reduce adverse events.

To determine the physical literacy, defined as the capability for a physically active lifestyle, of children with medical conditions compared with healthy peers, this multicenter cross-sectional study recruited children with medical conditions from cardiology, neurology (including concussion), rheumatology, mental health, respirology, oncology, hematology, and rehabilitation (including cerebral palsy) clinics. Participants aged 8-12 years (N = 130; mean age: 10.0 ± 1.44 years; 44% female) were randomly matched to 3 healthy peers from a normative database, based on age, gender, and month of testing. Total physical literacy was assessed by the Canadian Assessment of Physical Literacy, a validated assessment of physical literacy measuring physical competence, daily behaviour, knowledge/understanding, and motivation/confidence. Total physical literacy mean scores (/100) did not differ (t(498) = -0.67; p = 0.44) between participants (61.0 ± 14.2) and matched healthy peers (62.0 ± 10.7). Children with medical conditions had lower mean physical competence scores (/30; -6.5 [-7.44 to -5.51]; p < 0.001) but higher mean motivation/confidence scores (/30; 2.6 [1.67 to 3.63]; p < 0.001). Mean daily behaviour and knowledge/understanding scores did not differ from matches (/30; 1.8 [0.26 to 3.33]; p = 0.02;/10; -0.04 [-0.38 to 0.30]; p = 0.81; respectively). Children with medical conditions are motivated to be physically active but demonstrate impaired movement skills and fitness, suggesting the need for targeted interventions to improve their physical competence. Novelty: Physical literacy in children with diverse chronic medical conditions is similar to healthy peers. Children with medical conditions have lower physical competence than healthy peers, but higher motivation and confidence. Physical competence (motor skill, fitness) interventions, rather than motivation or education, are needed for these youth.
