Abstract

Objectives: To determine the prevalence of snoring and OSA and to identify risk factors associated with OSA in overweight children.

Methods: This is a cross-sectional study from 1st October 2009 till 31st January 2011 in University Malaya Medical Centre. Eighty-nine overweight children were enrolled by convenience sampling. Demographic data was collected. The Paediatric Sleep Questionnaire (PSQ) and Epworth Sleepiness Scale (EPSS) were administered, followed by simple examination. Patients who had a positive PSQ or EPSS score or had at least one significant symptom (secondary nocturnal enuresis, increased work of breathing or witnessed apnoea during sleep) or hypertension underwent a polysomnogram (PSG).

Results: Ninety-one percent (n = 81) of children were obese with median BMI 25.9 (IQR 22.5, 30.0). Sixty-four children (71.9%) snored with 28 (31.5%) being habitual snorers. A PSG was indicated in 34 children. One child defaulted follow-up. Twenty three (26.0%) children had OSA on PSG. Mouth breathing (from history) was a significant factor associated with OSA (p = 0.054, Adjusted OR 3.7, 95% CI 0.98, 13.7)

Conclusion: OSA is a significant problem in overweight children. Mouth breathing may be a significant factor associated with OSA.
