N2 - 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
