The study included 49 patients and assessed the association between anatomical factors and treatment outcome.
Researchers evaluated two pediatric SDB questionnaires in children undergoing orthodontic treatment, finding that 20% of subjects reported snoring and suggesting that family dentists may use simple questionnaires to identify preliminary risks of sleep-disordered breathing. Craniofacial abnormalities are a common cause of SDB in children.

A tightly controlled University of Rochester study found that eliminating gluten and casein from children with autism had no impact on their behavior, sleep or bowel patterns. Despite this, some subgroups of children may receive benefits from dietary changes, particularly those with significant gastrointestinal symptoms.

The study used EEG recordings to measure brain waves and found that 24 of 26 babies showed neural activity during sleep.
Children from poor families experience higher levels of externalizing and internalizing symptoms when they sleep poorly. In contrast, getting a good night's sleep protects against behavioral problems in minority children.
