Risk Factor of Obstructive Sleep Apnea Syndrome in Obese Early Adolescents: A Prediction Model Using Scoring System
Aim: to obtain the OSAS prevalence and risk factors of OSAS in obese early adolescents and to create a scoring system based on risk factors for diagnosing OSAS.
Methods: an observational study in Jakarta, November 2007 until December 2008 on obese adolescents aged 10-12 years with snoring. Subjects underwent clinical examination, lung function test, paranasal sinus X-ray, and polisomnography. Measured outcomes were diagnosis of OSAS; sensitivity, specificity, predictive values, and likelihood ratios of a scoring system based on risk factors.
Results: the prevalence of OSAS in obese early adolescents is 38.2% using AHI cut-off point of >3 on PSG. Tonsillar hypertrophy, adenoid hypertrophy, and neck circumference were the main risk factors. Scoring system was designed based on these results: OS= T + A + NC; OS= OSAS score; T= tonsil hypertrophy (>T3 scored 1, 0.8 scored 1.5, 34 cm scored 1;
