Detailed Description:
In a prospective cohort study, obese children will be recruited. After informed consent is obtained, all children will complete a standardized sleep questionnaire and a pediatric daily sleepiness scale questionnaire. All participants will undergo a complete physical examination, blood tests for lipid profile, liver enzymes, and Glucose and insulin will be obtained, and liver sonography will be performed to assess for the presence of fatty liver. Nasopharyngeal radiographs will be used to assess adenoidal size based on the method by Cohen and Konak. A standard in-laboratory, overnight polysomnography will be performed, within 2 weeks of enrollment to the study, in the sleep laboratory at Asaf Harofeh Medical Center. Children with severe obstructive sleep apnea, defined as apnea hypopnea index (AHI) > 15 will undergo adenotonsillectomy. All children will be referred for a dietary and physical education program. The first visit with the dietician will be considered day 1 of the study. Children will than be followed monthly by a dietician. After three months of follow-up, subjects will be divided into two groups. Group 1 will include all children who had AHI > 2 on the initial polysomnography (including children who underwent adenotonsillectomy for AHI > 15), and group 2 will consist of children who had AHI < 2 on the initial PSG. Children of group 2 will continue monthly dietary visits as before. Children from group 1 will undergo a second evaluation including questionnaires, laboratory blood tests, liver sonography, nasopharyngeal radiographs, and polysomnography. Children who demonstrate reduction in the AHI based on PSG will be offered to continue with dietary treatment alone. Children with no change in the AHI based on PSG will be offered to undergo adenotonsillectomy in addition to continued dietary management. All children will be followed for a total duration of six months. After six months, all children will be re-evaluated by questionnaires, blood tests, liver sonography, and nasopharyngeal radiographs. Polysomnography will be performed in all children who had an AHI > 2 on the second PSG.
