Sleep problems in low income, urban pediatric populations living at different altitudes in Colombia. Sleep Med 2022; 100:64-70. [PMID: 36027664 DOI: 10.1016/j.sleep.2022.07.017] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/18/2022] [Revised: 07/26/2022] [Accepted: 07/27/2022] [Indexed: 01/12/2023]
Abstract
OBJECTIVE To determine the frequency of sleep problems in low-income, urban pediatric populations in cities at different altitudes in Colombia. METHODS A descriptive, cross-sectional population-based observational study was conducted in children aged between 2 and 12 years in the low income, urban areas of three cities in Colombia (Santa Marta, Bucaramanga, and Bogotá) located at 15, 959, and 2640 m above sea level, respectively. Sociodemographic data were collected, and the Spanish version of the Pediatric Sleep Questionnaire was used. RESULTS 1989 children were surveyed, distributed as follows: Santa Marta (32.0%), Bucaramanga (33.4%), and Bogotá (34.6%). The overall prevalence of sleep problems was 39.0%. Children from Santa Marta had the highest frequency of parasomnias (58.0%); those from Bucaramanga had the highest frequency of attention deficit symptoms (4.0%) and apneic pauses witnessed by parents or caregivers (5.7%). Finally, Bogotá, the only high-altitude location, had the highest frequency of sleep disordered breathing (17.2%). CONCLUSIONS The study found a high frequency of sleep problems in the pediatric population, especially at higher altitudes when compared to lower altitude settings. Sleep disorders warrant early detection and timely therapeutic intervention.

Prevalence of sleep apnea in children and adolescents in Colombia according to the national health registry 2017–2021. PLoS One 2022; 17:e0273324. [PMID: 36044460 PMCID: PMC9432726 DOI: 10.1371/journal.pone.0273324] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/04/2022] [Accepted: 08/06/2022] [Indexed: 11/17/2022] Open
Abstract
Objective To describe the sociodemographic and epidemiological characteristics of diagnosis and treatment of pediatric patients with sleep apnea, both central and obstructive, in Colombia between 2017 and 2021. Methods Observational, descriptive, cross-sectional, epidemiological study using the International Classification of Diseases and Related Health Problems as search terms for sleep apnea, based on SISPRO, the Colombian national health registry. Stratification by gender and age groups was performed. We also generated data of the amount of diagnostic and therapeutic procedures performed. A map of prevalence by place of residency was performed. Results National records report 15200 cases of SA between 2017 and 2021, for an estimated prevalence of 21.1 cases by 100000 inhabitants in 2019 the year with the most cases (4769), being more frequent and in the 6 to 11 age group and in males, with a male to female ratio of 1.54:1. The number of cases declined in 2020 and 2021. The map showed a concentration of cases in the more developed departments of the country. Discussion This is the first approximation to a nation-wide prevalence of sleep apnea in Colombia which is lower to what is found in the literature worldwide, including studies performed in Latin America and in Colombia, this could reflect sub diagnosis and sub report. The fact that the highest prevalence was found in males and in the 6–11 age group is consistent with reports in literature. The decrease in cases in 2020 and 2021 could be related to the COVID-19 pandemic impact in sleep medicine services.

Neurocognitive Consequences in Children with Sleep Disordered Breathing: Who Is at Risk? CHILDREN 2022; 9:children9091278. [PMID: 36138586 PMCID: PMC9497121 DOI: 10.3390/children9091278] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 08/02/2022] [Revised: 08/22/2022] [Accepted: 08/22/2022] [Indexed: 11/23/2022]
Abstract
Sleep-disordered breathing (SDB) is a prevalent disease in children characterized by snoring and narrowing of the upper airway leading to gas exchange abnormalities during sleep as well as sleep fragmentation. SDB has been consistently associated with problematic behaviors and adverse neurocognitive consequences in children but causality and determinants of susceptibility remain incompletely defined. Since the 1990s several studies have enlightened these associations and consistently reported poorer academic performance, lower scores on neurocognitive tests, and behavioral abnormalities in children suffering from SDB. However, not all children with SDB develop such consequences, and severity of SDB based on standard diagnostic indices has often failed to discriminate among those children with or without neurocognitive risk. Accordingly, a search for discovery of markers and clinically useful tools that can detect those children at risk for developing cognitive and behavioral deficits has been ongoing. Here, we review the advances in this field and the search for possible detection approaches and unique phenotypes of children with SDB who are at greater risk of developing neurocognitive consequences.

Does sleep-disordered breathing add to impairments in academic performance and brain structure usually observed in children with overweight/obesity? Eur J Pediatr 2022; 181:2055-2065. [PMID: 35142932 PMCID: PMC9056447 DOI: 10.1007/s00431-022-04403-0] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/04/2021] [Revised: 01/26/2022] [Accepted: 01/29/2022] [Indexed: 12/01/2022]
Abstract
UNLABELLED Approximately 4-11% of children suffer from sleep-disordered breathing (SDB), and children with obesity are at increased risk. Both obesity and SDB have been separately associated with poorer brain health, yet whether SDB severity affects brain health in children with obesity remains unanswered. This study aimed to examine associations of SDB severity with academic performance and brain structure (i.e., total brain and gray and white matter volumes and gray matter volume in the hippocampus) in children with overweight/obesity. One hundred nine children aged 8-12 years with overweight/obesity were included. SDB severity and its subscales (i.e., snoring, daytime sleepiness, and inattention/hyperactivity) were evaluated via the Pediatric Sleep Questionnaire (PSQ), and academic performance was evaluated with the Woodcock-Muñoz standardized test and school grades. Brain structure was assessed by magnetic resonance imaging. SDB severity was not associated with academic performance measured by the standardized test (all |β|> 0.160, P > 0.076), yet it was associated with the school grade point average (β = -0.226, P = 0.007) and natural and social science grades (β = -0.269, P = 0.024). Intention/hyperactivity seemed to drive these associations. No associations were found between SDB severity and the remaining school grades (all β < -0.188, P > 0.065) or brain volumes (all P > 0.05). CONCLUSION Our study shows that SDB severity was associated with lower school grades, yet it was not associated with the standardized measurement of academic performance or with brain volumes in children with overweight/obesity. SDB severity may add to academic problems in children beyond the effects contributed by overweight/obesity status alone. WHAT IS KNOWN • Sleep-disordered breathing (SDB) may affect brain structure and academic performance in children. • Children with overweight/obesity are at higher risk for the development of SDB, yet the comorbid obesity-SDB relationship with brain health has not been investigated thus far. WHAT IS NEW • To our knowledge, this is the first study examining the associations of comorbid obesity-SDB severity with brain volumes and academic performance in children. • SDB symptoms may adversely affect academic performance at school in children with overweight/obesity, beyond the effects of weight status alone.

Obstructive sleep apnea in children with Down syndrome: is it possible to predict severe apnea? Eur J Pediatr 2022; 181:735-743. [PMID: 34562164 PMCID: PMC8475480 DOI: 10.1007/s00431-021-04267-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/07/2021] [Revised: 09/09/2021] [Accepted: 09/12/2021] [Indexed: 11/24/2022]
Abstract
The objectives are to explore the demographic and polysomnographic features of children with Down syndrome and to determine the predictive factors associated with severe sleep apnea. A total of 81 children with Down syndrome referred for full-night polysomnography were analyzed. In addition, parental interviews were performed for each child. Data were available for 81 children, with a mean age of 4.8 years. Severe obstructive sleep apnea was determined in 53.1%. Age, sex, exposure to second-hand smoke, clinical findings, anthropometric features, and the presence of comorbidities were not predictors of severe obstructive sleep apnea. Children who were exposed to second-hand smoke had more sleep-related symptoms. Even in children without symptoms, the prevalence of severe obstructive sleep apnea was 40%. Moreover, 86% of parents had no previous information regarding possible sleep breathing disorders in their children. Clinically significant central apnea was present in 10 patients (12.3%).Conclusion: Our results demonstrate that severe obstructive sleep apnea is common in children with Down syndrome, even in children without a history of symptoms of sleep apnea. It is not possible to predict patients with severe apnea; thus, screening of children with Down syndrome beginning from young ages is very important. Central apneas could be a part of the spectrum of sleep abnormalities in Down syndrome.

Abstract
STUDY OBJECTIVES Younger children and adolescents are exposed to various smart devices in the modern world, and their use of smart devices is rapidly increasing worldwide. Although smart devices have often been considered to have negative effects on sleep of children and adolescents, such effects have not been studied among younger children. Sleep is considered particularly important for learning and memory, and also has implications for emotional regulation and behavior. Therefore, this study was conducted to examine the effects of smartphone overuse on sleep in 5- to 8-year-old children. METHODS Participants were from the Kids Cohort for Understanding of Internet Addiction Risk Factors in Early Childhood (K-CURE) Study, an observational prospective cohort study in Korea. Smartphone screen time and total sleep time were assessed using parental questionnaires. Sleep problems of children were assessed using the Children's Sleep Habits Questionnaire (CSHQ). Analysis of covariance was used to examine the association between smartphone overuse and sleep habits in children. All statistical analyses were conducted using SPSS version 21.0 (IBM Corporation, Armonk, NY). RESULTS Total sleep time of the smartphone overuse group (smartphone use over 1 hour daily) was shorter than that of the control group (F = 6.362, P < .05). Children in the smartphone overuse group showed statistically significant higher scores in the CSHQ total score and nocturnal awakening subscale score (P < .05). CONCLUSIONS Excessive smartphone use was related to shorter total sleep time in children. Use of a smartphone was also associated with significant reductions in the quality of sleep in younger children.

Association Between Habitual Snoring and Cognitive Performance Among a Large Sample of Preadolescent Children. JAMA Otolaryngol Head Neck Surg 2021; 147:426-433. [PMID: 33630070 PMCID: PMC7907984 DOI: 10.1001/jamaoto.2020.5712] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/24/2020] [Accepted: 12/23/2020] [Indexed: 02/03/2023]
Abstract
Importance Previous studies have identified an association between habitual snoring and lower cognitive performance in children. However, whether and to what extent this association is confounded by pertinent demographic, anthropometric, and socioeconomic characteristics is unknown. Objective To assess the extent to which potential confounding factors modify the association between parent-reported habitual snoring and cognitive outcomes among a large and diverse sample of typically developing preadolescent children. Design, Setting, and Participants This cross-sectional analysis used a baseline data set (version 2.0.1) from children enrolled in the ongoing Adolescent Brain Cognitive Development study between September 1, 2016, and October 15, 2018. Children aged 9 to 10 years without serious psychiatric or neurological comorbidities were recruited at 21 research sites in the US. Study recruitment was designed to approximate the racial and socioeconomic diversity of the US population. Data were analyzed from February 1 to March 31, 2020. Exposures Parent-reported habitual snoring in children that occurs 3 or more nights per week. Main Outcomes and Measures Associations between habitual snoring and cognitive performance were assessed using the Sleep Disturbance Scale for Children and the National Institutes of Health Toolbox Cognition Battery, which includes 7 domain-specific and 3 composite (total cognitive function, fluid cognition, and crystallized cognition) standard scores that are uncorrected for covariates. Cognitive performance was examined before and after adjustment for covariates, which included age, sex, body mass index percentile, annual household income before taxes, and highest educational level of caregiver. The extent of confounding was assessed by the effect size, represented by Cohen d, before and after inclusion of covariates using linear mixed-effects models. Results A total of 11 873 children aged 9 to 10 years (6187 boys [52.1%]; 6174 White [52.0%]) with available data were included in the study. Of those, habitual snoring (≥3 nights per week) was reported in 810 children (6.8%), and nonhabitual snoring (1-2 nights per week) was reported in 4058 children (34.2%). In the unadjusted models, the total cognitive function composite score among children who habitually snored was significantly lower compared with children who never snored (Cohen d, 0.35; 95% CI, 0.28-0.42). Differences were also identified in the crystallized cognition (Cohen d, 0.34; 95% CI, 0.26-0.41) and fluid cognition (Cohen d, 0.28; 95% CI, 0.21-0.35) composite scores. The association between habitual snoring and cognitive performance was substantially attenuated after adjustment for covariates (Cohen d, 0.16 [95% CI, 0.09 to 0.24] for total cognitive function, 0.14 [95% CI, 0.07 to 0.21] for crystallized cognition, and 0.13 [95% CI, 0.06 to 0.21] for fluid cognition). Similar mitigation was also observed for all domain-specific scores. Conclusions In this cross-sectional study, when adjusted for baseline demographic, anthropometric, and socioeconomic characteristics, the association between parent-reported habitual snoring and cognitive performance was substantially attenuated among children aged 9 to 10 years.

Perinatal antecedents of sleep disturbances in schoolchildren. Sleep 2021; 43:5755896. [PMID: 32095821 DOI: 10.1093/sleep/zsaa021] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/15/2019] [Revised: 01/08/2020] [Indexed: 12/19/2022] Open
Abstract
STUDY OBJECTIVES Prematurity has been associated with an increased risk for sleep apnea. However, sleep disturbances in children born preterm have not been extensively investigated. Considering that determinants of sleep may originate early in life, the potential impact of prematurity on sleep disturbances later in life could be important. To establish the role of prematurity on sleep disturbances in a cohort of schoolchildren that were born preterm and compare them with healthy controls. METHODS A cohort of 147 schoolchildren, 45 born at term (≥37 weeks) and 102 very preterm (<32 weeks), was recruited and evaluated at school age (5-9 years). The Pediatric Sleep Questionnaire (PSQ) and the Sleep Disturbance Scale for Children (SDSC) were used to assess sleep disturbances in different domains. RESULTS PSQ score was significantly higher in former preterm children (0.26 ± 0.18 vs. 0.18 ± 0.14 in controls; p = 0.004), and SDSC total score was also significantly different among groups (21.7 ± 11.6 vs. 14.1 ± 12.6; p < 0.001). Regression models showed significant mean differences in PSQ score, total SDSC score, and two SDSC subscale scores (i.e. sleep-wake transition disorders, sleep-breathing disorders, and sleep hyperhidrosis) even after adjustment for confounders. Maternal age and type of delivery were not significantly associated with total PSQ scores. CONCLUSIONS Sleep disturbances may originate early in life since children born preterm exhibit an increased risk for developing long-term sleep problems. These findings may have important implications for management of preterm children and for implementation of early interventions focused on optimizing sleep habits.

Abstract
OBJECTIVE We assess behavioral and attentional problems and neurocognitive functioning in school-aged children with primary snoring (PS). METHODS Seventeen children with PS and 27 non-snoring peers aged 6-10 years took part in the study. All children underwent a polysomnography (PSG) at the Sleep Laboratory. Snoring was defined by parents and with PSG. Children with obstructive sleep apnea were excluded. The parents completed the Sleep Disturbance Scale for Children. Parents and teachers assessed behavioral and attentional problems with the Child Behavior Checklist and the Conners' Rating Scale-Revised. Neuropsychological assessment included the Wechsler Intelligence Scale for Children and the Developmental Neuropsychological Assessment (NEPSY test). RESULTS The PS group had significantly more parent-reported internalizing, total, and attentional problems than the control group. Teachers did not report behavioral problems in the PS group. The PS and control groups had equal IQ scores and similar core neurocognitive functions, except for one visuospatial subtest. The PS group had significantly more inspiratory flow limitation and increased diaphragmatic electromyography compared with the controls. Parents reported significantly more daytime sleepiness in the PS group. Daytime sleepiness and snoring time were consistently associated with more behavioral and attentional problems. Flow limitation and more oxygen saturation values under 90% were associated with attentional problems, higher oxygen desaturation index, and lower mean oxygen saturation percentage with reduced language functions. CONCLUSIONS Snoring with an increase in respiratory effort without apneas and hypopneas and parent-reported daytime sleepiness may be linked to daytime symptoms. School-aged children with PS are at risk for behavioral and attentional problems, but not cognitive impairments.

Overnight oximetry in children undergoing adenotonsillectomy: a single center experience. J Otolaryngol Head Neck Surg 2019; 48:69.

Abstract
Background Obstructive sleep apnea (OSA) is the most common indication for adenotonsillectomy in children. Home-based sleep oximetry continues to be used in the diagnosis of pediatric OSA despite a lack of correlation with lab-based polysomnography. This study investigates whether factors influence surgeons in selecting patients for home-based sleep oximetry, how the study findings are used in patient management, and whether abnormal oximetry findings are associated with post-operative complications. Methods A retrospective review was performed on children with suspected OSA who had undergone a tonsillectomy and/or an adenoidectomy over a three-year period. Demographic features, comorbidities, pre-operative oximetry results, and post-operative complications were recorded. Data analysis consisting primarily of logistic regression was performed using Stata 12.0 (College Station, Texas). Results Data was collected from 389 children. Two hundred and seventy-one children underwent pre-operative oximetry (69.7%). There was no significant association between age or the presence of comorbidities and the likelihood of undergoing pre-operative sleep oximetry. The post-operative complication rate was 0.8%. There was no significant association between abnormal sleep oximetry parameters and post-operative complications. Children with one or more abnormal sleep oximetry parameters were more likely to be observed in hospital for at least one night (OR 2.4, p < 0.0001). Conclusions Our study suggests that surgeons are using home-based sleep oximetry findings to inform the post-operative care of children with suspected OSA, as those with abnormal home-based sleep oximetry findings were more likely to be observed in hospital. These hospital admissions may be unnecessary given the poor correlation of home-based oximetry and PSG as well as the low rate of serious post-operative complications.

Abstract
BACKGROUND Habitually snoring children are at risk of manifesting disease-related problems even if their sleep studies are overall within normal limits. STUDY OBJECTIVES To compare sleep spindle activity in children with primary snoring and healthy controls. METHODS Sleep spindle activity including analysis of fast and slow spindles (ie, >13 Hz and <13 Hz, respectively) was evaluated in polysomnographic (PSG) recordings of 20 randomly selected children with primary snoring (PS; normal PSG recordings except for objective presence of snoring; 12 boys, mean age 6.5 ± 2.1 years), and 20 age- and gender-matched PSG-confirmed non-snoring controls. RESULTS PS children showed significantly lower spindle indices in all non-rapid eye movement (NREM) sleep stages (p < 0.05). In contrast, fast spindles were found in 40% (n = 8) children with PS and in 25% (n = 5) controls. Sleep spindle activity was particularly higher in NREM sleep stage 2 in controls compared PS (76% versus 43% of all marked sleep spindles events in NREM sleep stage 2, p < 0.001). CONCLUSIONS Children with PS exhibit significantly reduced spindle activity when compared to matched controls. Reduced sleep spindle activity may be an indicator of sleep disruption and, therefore, could be involved in the development of disease-related consequences in snoring children.

Abstract
OBJECTIVES To estimate via questionnaire within a population sample of New Zealand (NZ) children aged 6-to-10 years, the prevalence of sleep disordered breathing (SDB) and those struggling academically, and to identify individual and shared risk factors (health and demographic) for parent-reported SDB symptoms and academic difficulties. METHODS In this cross-sectional study, parents/caregivers of children were recruited through schools and social media to complete an online questionnaire covering health and demographic factors, their children's SDB symptoms (Pediatric Sleep Questionnaire; PSQ) and parental ratings of academic performance based on teacher feedback relative to expected progress in the national curriculum (well below/below/at/above) in reading, writing, and math. RESULTS A total of 1205 children (53% male) aged (mean) eight years two months were included, comprising 79.4% NZ European/other and 15.0% Māori. The survey-weighted prevalence of SDB (based on the PSQ) was 17.5%. This was higher amongst those with academic difficulties rated 'below/well below' expected progress for reading, writing and math (estimated at 24.0%, 31.0% and 27.5% respectively), with increased odds (adjusted odds ratios) for poor progress of 1.9 (95% CI: 1.2, 3.0), 1.8 (95% CI: 1.2, 2.7) and 2.4 (95% CI: 1.6, 3.7) respectively. There were no shared risk factors common to both SDB and academic difficulties identified from multivariate analyses. CONCLUSIONS The findings suggest that children with parent-reported SDB symptoms may be at high risk for poor progress in reading, writing, and math. Future research could examine whether treatment of SDB reduces barriers to learning and offsets educational risk.

Abstract
STUDY OBJECTIVES To assess spindle activity as possible markers for neurocognitive consequences in children with mild obstructive sleep apnea. METHODS Children aged 6-11 years diagnosed with mild OSA (i.e., an apnea hypopnea index <5.0) were recruited and compared with age and gender-matched healthy controls. Polysomnographic recordings were analyzed for sleep microstructure and spindle activity. All children completed also an intelligence test battery (i.e., the Wechsler intelligence test for children, 4th version). RESULTS Nineteen children with OSA (13 boys, mean age 7.1 ± 1.4 y), and 14 controls (7 boys, mean age 8.1 ± 1.9 y) were included. Mean IQ was 110 ± 12 for the complete sample, in children with OSA 111 ± 13, and in controls 108 ± 12 (p = 0.602). Controls showed a higher spindle index in N2 stage than children with OSA: 143.0 ± 42.5 vs 89.5 ± 56.9, respectively (p = 0.003). Spindle index in NREM was strongly and significantly correlated with Verbal Comprehension Index (VCI), Working Memory Index (WMI), Processing Speed Index (PSI), and total IQ in children with OSA. CONCLUSIONS Children with mild OSA demonstrate a different pattern of sleep spindle activity that seems to be linked with neurocognitive performance, especially concerning memory. Sleep spindle activity seems to be involved with mechanisms related with neurocognitive consequences in children with OSA.

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
OBJECTIVE To compare risk for sleep-disordered breathing between children with and without single-suture craniosynostosis. PARTICIPANTS A total of 184 children with single-suture craniosynostosis and 184 controls. MAIN OUTCOME MEASURES Parent reported sleep-disordered breathing-related symptoms. RESULTS Current sleep problems were reported in 19% of patients with single-suture craniosynostosis and 14% of controls (adjusted odds ratio = 1.6; 95% CI, 0.9 to 2.8). Ever having sleep problems was reported in 25% and 23% of cases and controls, respectively (adjusted odds ratio = 1.2; 95% CI, 0.7 to 1.9). Overall, snoring was statistically associated with single-suture craniosynostosis (P = .01) and was more often reported as 2+ nights per week (versus never) in patients with single-suture craniosynostosis (13%) than in controls (4%) (adjusted odds ratio = 3.5; 95% CI, 1.5 to 8.2). CONCLUSIONS Though preliminary, increased presence of snoring during sleep in children with single-suture craniosynostosis compared with controls suggests that children with isolated single-suture craniosynostosis may be at increased risk for sleep-disordered breathing. Further study using standardized assessments of sleep-disordered breathing is needed.

Polysomnography in Bolivian Children Native to High Altitude Compared to Children Native to Low Altitude. Sleep 2016; 39:2149-2155. [PMID: 27634793 DOI: 10.5665/sleep.6316] [Citation(s) in RCA: 16] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/21/2016] [Accepted: 08/02/2016] [Indexed: 11/03/2022] Open
Abstract
STUDY OBJECTIVES To compare polysomnographic parameters in high altitude (HA) native Andean children with low altitude (LA) native peers in order to explain the nocturnal oxyhemoglobin saturation (SpO2) instability reported in HA native children and to study the effect on sleep quality. METHODS Ninety-eight healthy children aged 7-10 y and 13-16 y were recruited at LA (500 m) or HA (3,650 m) above sea level. Physical examination was undertaken and genetic ancestry determined from salivary DNA to determine proportion of European ancestry, a risk factor for poor HA adaptation. Attended polysomnography was carried out over 1 night for 58 children at their resident location. RESULTS Of 98 children recruited, 85 met inclusion criteria, 58 of 85 (68.2%) completed polysomnography, of which 56 were adequate for analysis: 30 at LA (17 male) and 26 at HA (16 male). There were no altitude differences in genetic ancestry, but a high proportion of European admixture (median 50.6% LA; 44.0% HA). SpO2 was less stable at HA with mean 3% and 4% oxygen desaturation indices greater (both P < 0.001) than at LA. This was not explained by periodic breathing. However, more obstructive hypopnea was observed at HA (P < 0.001), along with a trend toward more central apnea (P = 0.053); neither was explained by clinical findings. There was no difference in sleep quality between altitudes. CONCLUSIONS HA native Andean children have more respiratory events when scoring relies on SpO2 desaturation due to inherent SpO2 instability. Use of American Academy of Sleep Medicine scoring criteria may yield false-positive results for obstructive sleep-disordered breathing at HA.

Increased severity of sleep-disordered breathing is associated with insomnia and excessive somnolence in primary school children. Sleep Med 2016; 23:1-5. [PMID: 27692270 DOI: 10.1016/j.sleep.2016.04.007] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/03/2016] [Revised: 03/31/2016] [Accepted: 04/02/2016] [Indexed: 10/21/2022]
Abstract
OBJECTIVE The aim of the study was to investigate the prevalence of difficulty with initiation or maintenance of sleep (DIMS) and excessive daytime sleepiness (EDS) in a general pediatric population, and to evaluate the relationship between these conditions and sleep-disordered breathing (SDB) symptom intensity. METHODS This population-based cross-sectional study from 27 primary schools in a medium-sized city in Poland was based on use of a questionnaire regarding demographic data, symptoms of SDB, DIMS, and EDS. Data were collected between September and December 2014. In all, 2940 caregivers were recruited and were asked to fill-out questionnaires and written consent. RESULTS A total of 68% of the questionnaires (n = 1987) were returned and analyzed. Habitual snoring (HS) was reported in 104 (5.3%) children. DIMS and EDS were seen in 137 children (6.9%) and 117 children (5.9%), respectively. The prevalence of DIMS increased from 3.5% in children who never snored to 28.6% in children who snored very often or always. Similarly, the prevalence of EDS was 2.7% in children who did not snore and increased to 19% in children who snored very often or always. No correlation was seen between increasing DIMS (r = 0.006, p > 0.05) or EDS (r = -0.031, p > 0.05) scores and body mass index. CONCLUSIONS This study is the first to measure the symptoms of both DIMS and EDS in a general pediatric population and to assess the relationship between both DIMS and EDS and SDB in children. We found that children with more frequent snoring had a higher prevalence of DIMS as well as EDS; however, there was no correlation between body mass index and either DIMS or EDS symptom severity.

Abstract
This study examined the prevalence of sleep disordered breathing (SDB) symptoms and their associations with daytime sleepiness, emotional problems, and school performance in Chinese children. Participants included 3979 children (10.99±0.99 years old) from four elementary schools in Jintan City, Jiangsu Province, China. Children completed a self-administered questionnaire on sleep behavior and emotional problems, while parents completed the Child Sleep Habit Questionnaire (CSHQ). SDB symptoms included 3 items: loud snoring, stopped breathing, and snorting/gasping during sleep. Teachers rated the children's school performance. The prevalence rates of parent- and self-reported SDB symptoms were 17.2% and 10.1% for "sometimes" and 8.9% and 5.6% for "usually". SDB symptoms, more prevalent in boys than in girls, increased the risks for depression, loneliness, and poor school performance. Daytime sleepiness mediated the relationship between SDB symptoms and depression, loneliness, and poor school performance. This study suggests the importance of early screening and intervention of SDB and daytime sleepiness in child behavioral and cognitive development.

Adaptation to Life in the High Andes: Nocturnal Oxyhemoglobin Saturation in Early Development. Sleep 2016; 39:1001-8.

Abstract
STUDY OBJECTIVES Physiological adaptation to high altitude hypoxia may be impaired in Andeans with significant European ancestry. The respiratory 'burden' of sleep may challenge adaptation, leading to relative nocturnal hypoxia. Developmental aspects of sleep-related breathing in high-altitude native children have not previously been reported. We aimed to determine the influence of development on diurnal-nocturnal oxyhemoglobin differences in children living at high altitude. METHODS This was a cross-sectional, observational study. Seventy-five healthy Bolivian children aged 6 mo to 17 y, native to low altitude (500 m), moderate high altitude (2,500 m), and high altitude (3,700 m) were recruited. Daytime resting pulse oximetry was compared to overnight recordings using Masimo radical oximeters. Genetic ancestry was determined from DNA samples. RESULTS Children had mixed European/Amerindian ancestry, with no significant differences between altitudes. Sixty-two participants had ≥ 5 h of nocturnal, artifact-free data. As predicted, diurnal mean oxyhemoglobin saturation decreased across altitudes (infants and children, both P < 0.001), with lowest diurnal values at high altitude in infants. At high altitude, there was a greater drop in nocturnal mean oxyhemoglobin saturation (infants, P < 0.001; children, P = 0.039) and an increase in variability (all P ≤ 0.001) compared to low altitude. Importantly, diurnal to nocturnal altitude differences diminished (P = 0.036), from infancy to childhood, with no further change during adolescence. CONCLUSIONS Physiological adaptation to high-altitude living in native Andeans is unlikely to compensate for the significant differences we observed between diurnal and nocturnal oxyhemoglobin saturation, most marked in infancy. This vulnerability to sleep-related hypoxia in early childhood has potential lifespan implications. Future studies should characterize the sleep- related respiratory physiology underpinning our observations.

Abstract
OBJECTIVE To investigate the technical feasibility of unattended home polysomnography (HPSG) in children with Down syndrome. METHODS Data from children with Down syndrome under 10 years of age referred to a diagnostic sleep study was analyzed. A full sleep-lab based polysomnography (PSG) or a HPSG with a portable device was performed. Uninterpretable HPSGs were defined as: recordings with (i) loss of ≥2 of the following channels: nasal flow, or thoracoabdominal sensors, or (ii) HPSG with less than 4h of artifact-free recording time or (iii) less than 4h SpO2 (peripheral capillary oxygen saturation) signal. RESULTS A total of 44 children (68% males) were included in the study, with a mean age of 3.6 (0.1-10) years. PSG was performed in 8 cases and HPSG in 36 cases. Six HPSG recordings were classified as uninterpretable and had to be repeated. Age, gender and BMI were no significant predictors of uninterpretability of the HPSG. Obstructive sleep apnea (OSA) was present in 61% (n=27) of all subjects, and classified as mild, moderate, and severe in 43% (n=19), 11% (n=5), and 7% (n=3) of cases, respectively. Interpretable and technically acceptable HPSGs were obtained in 30 subjects (83%). Age, gender and BMI were no significant predictors for interpretability of the HPSG. DISCUSSION This study demonstrates that a portable polysomnographic home device may be helpful for diagnosing OSA in children with Down syndrome. Considering the potential consequences of untreated OSA, this screening test may be helpful for early diagnosis of OSA in children with Down syndrome.

Abstract
We examined the association between sleep-disordered breathing (SDB) and disruptive behavior disorders in 605 children participating in a population-based cohort study. Nineteen percent of children snored (sometimes or often) and 10% had obstructive sleep apnea (OSA) symptoms. Thirteen percent had an ADHD diagnosis or symptoms and 5-9% had behavioral problems or a conduct disorder. Snoring or OSA symptoms were associated with a twofold difference in the odds of ADHD diagnosis or symptoms. OSA symptoms were associated with a threefold to fourfold difference in the odds of behavioral problems or conduct disorder. Clinicians should consider inquiring about SDB in children with disruptive behavior disorders and should also consider disruptive behavior disorders as potential sequelae of SDB.

Abstract
BACKGROUND Prevalence and potential risk contributors of sleep-disordered breathing (SDB) in adolescents and younger adults remain unclear. We hypothesized that SDB prevalence in younger Hispanic adults is higher than the limited evidence indicates. METHODS This is a population-based study of Hispanic subjects surveyed as part of the Chilean National Health Survey database. For this study, only subjects aged 15 to 40 years were included. Sleep and demographic questionnaires were used to assess SDB prevalence and its risk factors. Anthropometric measurements were performed in each subject. Prevalence was calculated for each SDB-related symptom. A regression model was constructed to investigate demographic risk factors of SDB. RESULTS A total of 2,147 subjects were included. Mean age (± SD) was 27.2 ± 7.2 years, n = 899 (42%) were men. Habitual snoring was highly prevalent, with an average of 53.8% in men and 38.3% in women. Snoring, witnessed apneas, and daytime somnolence increased continuously with age, with an abnormal SDB questionnaire score detected in 2.5%. Reported sleep duration was 7.61 ± 1.67 hours during weekdays and 8.27 ± 2.11 hours during weekends. Snoring frequency was significantly higher in men than women at nearly all age groups, and an adjusted regression model (OR [95% CI]) identified male sex (2 [1.6-2.5]; P < .001) and BMI (1.08 [1.03-1.12]; P < .001) as independent risk factors for snoring. CONCLUSION The risk of SDB is highly prevalent in younger adults, even in females, and increases with age and BMI. The high prevalence and low awareness justify active screening and treatment of SDB in this population.

Abstract
BACKGROUND AND OBJECTIVE Sleep-disordered breathing (SDB) in children is associated with daytime functioning decrements in cognitive performance and behavioral regulation. Studies addressing academic achievement are underrepresented. This study aimed to evaluate the strength of the relationships between SDB and achievement in core domains and general school performance. METHODS Data sources included PubMed, Web of Science, CINAHL, and PsycINFO. Studies of school-aged children investigating the relationships between SDB and academic achievement were selected for inclusion in a systematic literature review using Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Data extracted were converted into standardized mean differences; effect sizes (ES) and statistics were calculated by using random-effects models. Heterogeneity tests (I(2)) were conducted. RESULTS Of 488 studies, 16 met eligibility criteria. SDB was significantly associated with poorer academic performance for core academic domains related to language arts (ES -0.31; P < .001; I(2) = 74%), math (ES -0.33; P < .001; I(2) = 55%), and science (ES -0.29; P = .001; I(2) = 0%), and with unsatisfactory progress/learning problems (ES -0.23; P < .001; I(2) = 0%) but not general school performance. CONCLUSIONS Variable definitions of both academic performance and SDB likely contributed to the heterogeneity among published investigations. Clear links between SDB and poorer academic performance in school-age children are demonstrated. ES statistics were in the small to medium range, but nevertheless the findings serve to highlight to parents, teachers, and clinicians that SDB in children may contribute to academic difficulties some children face.

Abstract
OBJECTIVE To determine the association between the change in weight status and newly developed snoring in children. DESIGN This was a prospective cohort study. SETTING Structured interviews were conducted at participants' homes, and physical examinations were performed at The-pa Community Hospital in Southern Thailand. PARTICIPANTS Cohort subjects (n = 1076) were recruited from children born over a 1-year period between November 2000 and October 2001 in The-pa District of Songkhla Province, Southern Thailand. Data collection was performed when the child was 5 and 8.5 years old. MAIN OUTCOME MEASURES The child's snoring, weight, height and tonsillar size were examined. The change in weight status was categorised into four groups: not obese, became not obese, became obese and persistently obese. RESULTS Of 1076, 983 subjects (91.4%) completed both surveys. The overall prevalence of habitual snoring decreased from 13% at age 5 to 10.9% at age 8.5 years. Of the 855 children who reported not snoring in the first survey, 61 (7.1%) had become habitual snorers. After adjusting for tonsillar size, children who had become obese or were persistently obese had a significant association with becoming a new snorer with an odds ratio of 5.8 (Confidence interval, CI, 1.3-25.8) and 11.7 (CI, 2.5-54.9), respectively. CONCLUSIONS Children with newly developed obesity at 8.5 years old were strongly associated with new snoring occurrence, which is similar to the findings of long-term follow-up studies in adults. Our findings support the idea that the patterns of changes in weight status and snoring development in adults begin as early as the primary school years.

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
OBJECTIVE To investigate the technical feasibility of unattended polysomnography (HPSG) for diagnosis of obstructive sleep apnea (OSA) in children. METHODS A single-night HPSG was performed on children referred to the pediatric respiratory laboratory. Non-interpretable HPSGs were defined as: recordings with (i) loss of ≥2 of the following channels: nasal flow, or thoraco-abdominal belts, or (ii) HPSG with less than 4 h of artifact-free recording time or (iii) less than 4 h SpO2 signal. RESULTS Of n = 101 included HPSGs, n = 75 were ambulatory and n = 26 in hospitalized subjects. Median (minimum-maximum) age was 2.8 (0-15.4) years. Interpretable and technically acceptable recordings were obtained in 94 subjects (93%). Only 7 recordings (4 at home versus 3 in hospitalized subjects, p-value = 0.254) were classified as non-interpretable and had to be repeated. Artifact-free recording time was 461 (23-766)min. Complete artifact-free pulse oximetry signal was obtained in 14% of the included subjects. Neither age, gender, AHI, nor place of performance was significantly associated with the interpretability of recordings. DISCUSSION HPSG showed a high rate of interpretability and technical acceptance. The high technical feasibility obtained by HPSG may help to improve simple screening tests for OSA in children.
