Abstract

Childhood sleep disordered breathing (SDB) peaks in the preschool years. We aimed to compare the effects of SDB on polysomnographic characteristics between preschool and school aged children. PARTICIPANTS AND METHODS: One hundred and fifty-two preschool (3-5y) and 105 school-aged (7-12y) children, referred for assessment of SDB, plus controls (39, 3-5y and 34, 7-12y) with no history of snoring underwent overnight polysomnography. Subjects were grouped by their obstructive apnea hypopnea index (AHI) into those with primary snoring, mild obstructive sleep apnea (OSA), and moderate/severe OSA. The effects of SDB severity on sleep architecture and respiratory characteristics were compared between the age cohorts using quantile regression. RESULTS: There was an average reduction in median sleep efficiency of 3.5 (p=0.004) and an average increase in median WASO of 2 (p=0.08) between the age cohorts across the severity groups, with sleep efficiency falling and WASO increasing with increasing SDB severity in the school-aged, but not the preschool, cohort. There was an average difference in median central AHI of 0.6events/h (p
