- In adults and adolescents with asthma, use of ≥3 short-acting β2 -agonist (SABA) canisters/year is associated with increased exacerbation risk. Whether this association is present in younger children remains unknown. In this SABA use IN Asthma (SABINA) Junior study, we assessed the association of SABA collection with exacerbation risk in the general Swedish pediatric asthma population.This population-based cohort study utilized linked data from the Swedish national healthcare registries involving patients with asthma (<18years) treated in secondary care between 2006-2015. Exacerbation risk, by baseline SABA collection (0-2 vs. ≥3 canisters, further examined as ordinal/continuous variable) and stratified on comorbid atopic disease (allergic rhinitis, dermatitis and eczema, and food/other allergies), was assessed for 1-year follow-up using negative binomial regression.Of 219,561 patients assessed, 45.4%, 31.7%, and 26.5% of patients aged 0-5, 6-11, and 12-17years, respectively, collected ≥3 SABA canisters during the baseline year (high use). Collection of ≥3 SABA canisters (vs. 0-2) was associated with increased exacerbation risk during follow-up (incidence rate ratios [95% confidence interval]: 1.35 [1.29-1.42], 1.22 [1.15-1.29], and 1.26 [1.19-1.34] for 0-5-, 6-11-, and 12-17-year-olds, respectively); the association persisted with SABA as a continuous variable and was stronger among patients without atopic diseases (32%-44% increased risk versus. 14%-21% for those with atopic disease across groups).High SABA use was associated with increased asthma exacerbation risk in children, particularly in those without comorbid atopic diseases, emphasizing the need for asthma medication reviews and reformative initiatives by caregivers and healthcare providers on SABA use.
