The prevalence of sleep-disordered breathing in children with asthma and its behavioral effects.

Objectives: To determine the prevalence of sleep-disordered breathing (SDB) in children with asthma compared to non-asthmatic children and to determine if behavior problems are associated with asthma and SDB.

Study Design: Cross-Sectional.

Methods: Parents of 263 children with asthma and 266 controls ages 2 to 15 years attending routine pediatric office visits completed the Pediatric Sleep Questionnaire (PSQ) and the Child Behavior Checklist.
