BACKGROUND: The UK government has recommended the development of obesity services for children. As obesity is common, studying every obese child for obstructive sleep apnoea (OSA) would be challenging and full paediatric sleep services are not available in every area in Europe. The purpose of this study was to consider how well clinical features predict significant OSA in obese children in order to help prioritise the need for sleep studies and subsequent treatment. METHODS: Consecutive children referred for obesity management aged 2-16 years with a body mass index (BMI) of >2.5 z scores for age were offered a sleep study using overnight oximetry and audiovisual recordings. Significant OSA was defined as > or = 5 dips/h of >4% oxygen saturation or > or = 5 respiratory-event related arousals/h. RESULTS: Forty-one of 158 (26%) children (mean BMI z score 3.7) had significant OSA and 95% of these had either reported apnoea, restless sleep or tonsillar hypertrophy (TH). Nineteen percent of all children had none of these features. BMI was not related to OSA. CONCLUSION: If only obese children with reported apnoea, restless sleep or TH have a sleep study, 95% of all obese children with significant OSA will be identified using this method.
