Hearing loss mediates executive function impairment in sleep-disordered breathing

Abstract:

Background Sleep-disordered breathing (SDB) is often co-morbid with conductive hearing loss in early childhood due to a shared aetiology of adenotonsillar hypertrophy. Hearing loss is independently associated with impairment of executive function and behavioural difficulties. We hypothesised that these impairments in children with SDB may be mediated through hearing loss. Methods Fifty-eight children including 37 snorers awaiting adenotonsillectomy and 21 healthy non-snoring controls, aged 3–5 years, were assessed with pure tone audiometry, Strengths and Difficulties (SDQ), Behaviour Rating of Executive Function (BRIEF-P), and Childhood Middle Ear Disease and Hearing questionnaires. Polysomnography in snoring children generated an obstructive apnoea/hypopnea index (OAHI). Two regression models examined the effect of SDB and the mediating impact of hearing loss on BRIEF and SDQ …
