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.

Validation of a clinical assessment score for pediatric sleep-disordered breathing.

Objectives/hypothesis: To validate a clinical assessment score for pediatric sleep-disordered breathing.

Study Design: Prospective instrument validation.

Methods: One hundred children scheduled for overnight polysomnography were evaluated by a standardized history and physical examination and assigned a clinical assessment score.
