Sleep disordered breathing in children with Down syndrome in the Republic of Ireland.

Down syndrome (DS) is associated with a complex respiratory phenotype, including obstructive sleep apnea syndrome (OSAS). The study explored parent-reported prevalence and presentation of OSAS symptoms in children and adolescents with DS in Ireland. It also investigated treatment and compliance in those who have OSAS. A cross-sectional survey was distributed to parents registered with Down Syndrome Ireland (DSI) (n = 1,343). Data was collated and analyzed using SPSS v23. The response rate was 393 (29%). Twenty-one percent of parents (n = 84) reported a diagnosis of OSAS in their child. The parents of children reported as compliant with continuous positive airway pressure (CPAP) were more likely to report a perceived benefit of treatment (p = .018). Ninety-two percent (n = 212) of children without a formal diagnosis of OSAS had at least one symptom (median 4 symptoms) of the condition. This, the largest survey of parental reporting of OSAS or its symptoms, demonstrates a high reported prevalence of symptoms in children and adolescents with DS in Ireland without a formal diagnosis of OSAS, indicating under-recognition. In treated patients, perception of the benefit of CPAP correlated with reported compliance, suggesting a need for tailored education.
