Introduction: Cognitive and behavioral symptoms are associated with
sleep-disordered breathing (SDB) in children but resolution after treatment
by adenotonsillectomy (AT) is variable. Children’s body mass
index (BMI) and age could influence outcomes, but have not been extensively
examined in this context.
Methods: Children (n=100, age 3-8 years) referred for AT, based on
office visits only, were evaluated before and 6 months after surgery.
Evaluations included: height, weight, nocturnal polysomnography, neuropsychological
tests, and parent behavioral ratings. SDB was defined
by a respiratory disturbance index (RDI)>1. Repeated Measures ANO-
VAs were computed to examine effects of Age (3-5, 5.1-8 years), BMI
