Dysfunctional breathing was a frequent comorbidity among children and adolescents with asthma, with correlations with perceived poorer asthma control, according to a study published in Pediatric Allergy and Immunology.
Also, dysfunctional breathing (DB) was more common among adolescent girls and was associated with greater use of beta 2 agonists, Signe Vahlkvist, MD, PhD, department of pediatrics and adolescent medicine, Lillebaelt Hospital, University Hospital of Southern Denmark, and colleagues wrote.
The study involved 363 patients (median age, 13.8 years; 49% boys) aged 10 to 17 years
