Gunnlaugsson S, Greco KF, Petty CR, et al. - Researchers intended to determine if there is an association between sleep-disordered breathing (SDB) and asthma control and lung function among boys and girls within a pediatric severe asthma cohort. Patients attending clinic visits at the Boston Children’s Hospital Pediatric Severe Asthma Program finished the Pediatric Sleep Questionnaire (PSQ), Asthma Control Test (ACT) and Spirometry. Participants in the study were 37 patients, mean age 11.8 years (4.4) and 23 (62.2%) of them were male. Data reported that the prevalence of SDB was 43.2%. Children with severe asthma are more likely to develop SDB. Among children with severe asthma, SDB in girls predicts significantly worse asthma control than SDB in boys.
