Introduction: Sleep apnoea-hypopnoea syndrome (SAHS) and childhood obesity are two high prevalence conditions that represent a public health challenge. Objective: To analyse the association between both and comparing child groups that had or did not have both conditions. Patients and methods: A prospective study in children (3–14 years), referred to the “Multidisciplinary Sleep Unit” due to suspected SAHS, between 1 November 2015 and 1 August 2017. The following parameters were evaluated: anthropometry, symptoms, blood pressure, ear, nose, and throat examination, polysomnography (nocturnal PSG) and laboratory tests. Results: A total of 67 children were evaluated (64% non-obese (NOb) and 36% obese (Ob). It was observed that the Ob were older (P

Introduction: Obstructive sleep apnoea (OSA) is highly prevalent in children and a major public health problem. An attempt is made to determine the clinical and polysomnographic presentation of paediatric OSA in our area. Patients and methods: Retrospective descriptive study of sleep tests conducted on children up to 14 years old from 1999 to 2012 in the Sleep Unit of the University Hospital of Albacete. Age, gender, anthropometric, clinical data, indication and variables of sleep study, treatment, and outcomes were collected. Results: The study included 234 children. OSA was found in 71.8%, with 42.3% moderate and 44.6% severe. The majority were male (60.7%) and the mean age was 5 years, of whom 78% were pre-school or school age. There was overweight/obesity in 44%, with 93.4% snoring, apnoea 84.5%, and 5.4% daytime sleepiness. There were 23 polysomnographies and 145 polygraphies, with a median apnoea/hypopnoea index (AHI) of 10, SatO2 minimum 84%, desaturation index 8, and mean sleep supine 53.65% and supine events 57.61%. Treatment was lifestyle modifications 29.2%, CPAP 6%, and surgery 42.9%. Improved snoring and/or apnoea 69.4%, and weight 32.4% of overweight/obesity children. Conclusions: Most of the studied children had a pathological AHI. Almost half were overweight/obese, and a high percentage had moderate-severe OSA. Most frequent treatment was surgery. The clinical outcome was favourable in almost 70%. Less than a third with OSA and overweight/obesity improved weight. Resumen: Introducción: El síndrome de apneas-hipopneas del sueño (SAHS) es altamente prevalente en la edad pediátrica y un problema importante de salud pública. Se pretende conocer la presentación clínica y polisomnográfica del SAHS infantil en nuestro medio. Pacientes y métodos: Estudio descriptivo retrospectivo de los estudios del sueño realizados a menores de 14 años desde 1999 hasta 2012 en la Unidad del Sueño del Complejo Hospitalario Universitario de Albacete. Se recogen edad, sexo, datos antropométricos, clínicos, indicación y variables del estudio del sueño, tratamiento y evolución. Resultados: Doscientos treinta y cuatro niños. SAHS el 71,8%: moderado 42,3% y grave 44,6%. 60,7% varones y mediana de edad 5 años; el 78% en edad preescolar o escolar. Presentaban sobrepeso/obesidad 44%, ronquidos 93,4%, apneas 84,5% y somnolencia diurna 5,4%; 23 polisomnografías y 145 poligrafías: mediana de índice de apneas-hipopneas (IAH) 10, de SatO2 mínima 84% y de índice de desaturaciones 8, y media de sueño en supino 53,65% y de eventos en supino 57,61%. El tratamiento fue medidas higiénico-dietéticas en el 29,2%, CPAP el 6% y cirugía el 42,9%. Mejoraron los ronquidos y/o apneas el 69,4% y el peso el 32,4% de los niños con sobrepeso/obesidad. Conclusiones: La mayoría de los niños estudiados tenían un IAH patológico. Casi la mitad presentaban sobrepeso/obesidad y un alto porcentaje tenía SAHS moderado-grave. El tratamiento más indicado fue la cirugía. La evolución clínica fue favorable en casi el 70%. Menos de un tercio con SAHS y sobrepeso/obesidad mejoraron el peso.
