Treatment of sleep-disordered breathing (SDB) improves asthma outcomes in children undergoing adenotonsillectomy (T&A), a new study found. The prospective cohort study included 80 children with diagnosed asthma (aged 4‒11 years) undergoing T&A and 62 controls matched by age, sex, and asthma severity classification. Parents and children completed the Childhood Asthma Control Test (C-ACT) and the Pediatric Sleep Questionnaire (PSQ). Parents were queried regarding the number of asthma exacerbations, frequency of the use of systemic steroids, the number of emergency room visits, and the number of hospitalization in the prior 6 months. The identical questionnaires and interviews were completed 6 months after entry. Researchers found:
- The adjusted mean C-ACT score was 21.86 at entry and 25.15 at follow up for the T&A group vs 22.42 and 23.59 for the control group.
- There was a significant group by time interaction.
- Group means did not differ at entry but did differ at follow-up.
- Baseline PSQ was a significant predictor of improvement in C-ACT scores.
