Effects of Adenotonsillectomy on Parent-Reported Behavior in Children With Obstructive Sleep Apnea.

Area of Science:

• Pediatric Otolaryngology
• Sleep Medicine
• Child Psychology

Background:

• Childhood obstructive sleep apnea syndrome (OSAS) is linked to behavioral abnormalities.
• Previous studies on OSAS treatment effects on behavior have yielded conflicting results and often lacked randomized designs.
• Behavioral outcome measures in prior studies may have been confounded by sleep-related symptoms.

Purpose of the Study:

• To investigate the impact of adenotonsillectomy on behavioral outcomes in children diagnosed with OSAS.
• To determine if surgical intervention improves behavioral ratings, independent of sleep-specific symptom reporting.

Main Methods:

• A secondary analysis was conducted on Child Behavior Checklist (CBCL) data from the Childhood Adenotonsillectomy Trial (CHAT).
• Data from 380 children (aged 5-9 years) with OSAS were analyzed, comparing early adenotonsillectomy (eAT) to watchful waiting with supportive care (WWSC).
• Analyses were performed with and without the exclusion of sleep-specific items from the CBCL.

Main Results:

• A high prevalence of behavioral problems was observed at baseline (16.6% in the clinically abnormal range).
• Children undergoing eAT showed significant improvements in Total Problems, Internalizing Behaviors, Somatic Complaints, and Thought Problems compared to the WWSC group.
• Behavioral improvements in the eAT group remained significant even after excluding sleep-related items, with notable gains in Total and Other problems.

Conclusions:

• Adenotonsillectomy is an effective treatment for improving parent-rated behavioral problems in children with OSAS.
• The positive behavioral effects of adenotonsillectomy extend beyond sleep-specific symptoms.
• While adenotonsillectomy improved behavior in all children, further research is needed to understand disparities in treatment response among different racial groups.
