Introduction
Obstructive sleep apnoea (OSA) produces significant morbidity especially in the overweight but confirmatory
polysomnogram (PSG) is not readily available.
Objectives
To determine the prevalence of snoring and OSA in overweight children in a tertiary hospital and to identify
risk factors associated with OSA in these children.
Methodology
In this cross-sectional study from 1st October 2009 till 31st January 2011, 89 overweight children seen in UMMC
paediatric clinics and wards were enrolled by convenience sampling. A set of questionnaires pertaining
to demographic data, a Paediatric Sleep Questionnaire (PSQ) and Epworth Sleepiness Scale (EPSS) were
administered, followed by a simple examination. Patients who had positive sleep scores or had at least one
significant symptom of OSA (secondary nocturnal enuresis, increased work of breathing or witnessed apnoea
during sleep) underwent a PSG. Results were analysed using SPSS17.
Results
Ninety-one percent (n = 81) of children were obese. Sixty-four children (71.9%) snored with 28(31.5%) being
habitual snorers. A PSG was indicated in 32 children (24 completed). Fourteen children had OSA on PSG.
Factors that were significantly associated with OSA were mouth breathing (both on parental report and
physical examination), secondary nocturnal enuresis, difficulty in breathing at night and observed apnoea
during sleep, high EPSS score, and tonsillar size. In multivariate logistic regression, the EPSS score (p =
0.013) and difficulty in breathing at night (p
