Abstract

Background Allergy and respiratory viral infection may contribute to the pathogenesis of sleep disordered breathing (SDB) through promoting adenotonsillar growth. We investigated the seasonal variation of SDB in children by analysing the change in the obstructive apnoea hypopnoea index (OAHI) throughout the year. Participants 257 3-12-year-old children referred for assessment of SDB underwent overnight polysomnography (PSG). Results Mean seasonal OAHI was significantly higher in winter (5.1+/-0.8 events/h) and spring (4.6+/-0.9 events/h) compared with autumn (2.4+/-0.8 events/h; p
