“…Katz et al in their study on 6-17 year children stated that neck circumference >95 th percentile for age and sex has got significantly increased risk of OSA 17 The study reveals that the cases that are positive for SDB were in the order of obesity > adenotonsillar hypertrophy unlike the study conducted by Nanaware et al wherein positive SDB cases were in the order of craniofacial abnormalities > neuromuscular and skeletal disorders > adenotonsillar hypertrophy etc. 18 Our study reveals that there is a positive correlation between AHI and obesity but the degree of obesity doesn't predict the severity of OSA in children which similar to study done by Tripuraneni et al 19 …”

Background: Obstructive sleep apnoea syndrome (OSAS) is a spectrum which includes primary snoring, upper airway resistance syndrome, obstructive hypoventilation and obstructive sleep apnoea. Sleep disordered breathing (SDB) is characterized by snoring, witnessed apnoea, frequent arousal, mouth breathing, restless sleep, irritability, recurrent upper respiratory tract infections etc. Methods: This was a prospective observational study which included 20 children who presented to the otorhinolaryngology, pulmonary medicine, paediatric, oral and maxillofacial department were included in the study with clinical symptoms of obstructive sleep apnoea. Results: 20 children, 13 (65%) males and 7 (35%) females were included. Snoring was the most common complaint.15 (75%) were obese, 5 had adenotonsillar hypertrophy(25%) as the risk factor for OSA. 15 out of the 20 children were graded under mallampati class 1(75%), 4 class 2(20%), 1under class 3(5%). There was no significant association in severity of OSA between 2 genders (p=0.82). Positive correlation (r=0.52) was found between AHI and BMI and is found to be statistically significant (p=0.02), which suggests that degree of obesity does predict the severity of OSA. Conclusions: Obesity is the most significant risk factor among them followed by adenotonsillar hypertrophy. Hence children who snore should undergo polysomnography and necessary corrective measures should be prescribed.

“…Conflicting mechanisms have been proposed, however, in the attempt to explain how OSAS may lead to central apnea augmentation. Partial or complete collapse of the pharynx may stimulate mechanoreceptors in the airway and, through a reflex mechanism, inhibit central respiratory drive . An alternative mechanism that has also been proposed hypothesized that in children with both CSAS and OSAS, the apneic CO 2 threshold may be close to the spontaneous‐breathing CO 2 threshold, and changes in PCO 2 during sleep may then result in a temporary cessation of respiratory drive, resulting in central apnea events.…”

Background Although the pathogenesis of central and obstructive events seems to be different, these two entities may somehow be related. We aimed to determine whether, as reported in previous research, the number of central sleep apnea (CSA) cases in a population of children with obstructive sleep apnea syndrome (OSAS) was greater than in patients without obstructive events, and if CSA worsens with increasing OSAS severity. As a second objective, we analyzed changes in central apnea index (CAI) after adenotonsillar surgery compared to changes when no surgery has been performed. Methods We retrospectively reviewed nocturnal polysomnography (PSG) data from children between 1 and 14 years of age with no neurological conditions or syndromes. Patients with CAI values greater than 5 per hour were diagnosed as having CSA. Improvements of greater than 50% in CAI on repeat PSG were considered to represent a real change. Results Data were available from 1279 PSG studies, resulting in 72 children with a CAI greater than 5 per hour (5.6%). Patients with OSAS showed a higher CAI (2.16) compared with those without OSAS (1.17), and this correlation increased with higher degrees of obstructive apnea severity. When adenotonsillectomy was performed due to OSAS, the CAI decreased by 1.37. The average decrease in PSG values was only 0.38 in cases where no surgery was performed. Conclusion The results of this study suggest that although CSA is perceived to be mostly associated with central nervous system ventilatory control, there may be a connection with airway obstruction and in children with CSA and OSA diagnosis adenotonsillectomy may improve both conditions.

“…In the study of Nafiu et al [29] it was possible to demonstrate a correlation between NC and BMI and high blood pressure in a sample of 1,058 children aged 6-18 years, who had an incidence of overweight and obesity was 19.0 and 18.7%, respectively. Katz et al [30] also described NC as a risk factor for obstructive sleep apnea for boys >12 years.…”

Purpose: The purpose of this study was to verify the correlation between neck circumference (NC) and body mass index (BMI) in children, and to determine NC percentiles for Brazilian children. Methods: The subjects of this cross-sectional study were students between the ages of 6 and 19 years from five schools in São Paulo, Brazil. Clinical and anthropometric data were collected from the students from April 2011 to June 2012. NC was measured at the level of the cricoid cartilage. We calculated Pearson correlation coefficients between NC and other indices of obesity with Sigma Stat 3.5. NC percentiles were produced using the LMS (lambda, mu, and sigma) method (STATA 12.0). Results: Among 2,794 students, 49.9% were male. NC was significantly correlated with age, BMI, waist circumference (WC), and body fat percentage (%BF). The NC of boys was greater than that of girls. The NC curves of smoothed 3rd, 10th, 25th, 50th, 75th, 90th, and 97th percentiles were constructed by age and sex. Conclusions: NC can be used in the assessment of obesity in childhood. There was a positive correlation between NC and BMI, WC and %BF. This study was the first to provide NC percentiles for children in Brazil.

Neck circumference percentile: A screening tool for pediatric obstructive sleep apnea

Abstract: Children and youth with NC>95th percentile for age and sex have significantly increased risk of OSA. This effect is significant in males ≥ 12 years, whereas BMI is not. NC percentile may be an additional screening tool for OSA in children and youth.
