Abstract
Background
School based asthma programs have demonstrated that preventive asthma therapy administered in school reduces asthma morbidity. The burden of co-morbid allergic disease on asthma outcomes in a large school based asthma cohort has been unexplored.
Objective
Evaluate the prevalence of allergic rhinitis (AR) in historically minoritized school children with persistent asthma, and determine if AR is an independent risk factor for asthma morbidity.
Methods
We evaluated the prevalence of AR in children enrolled in 3 NIH funded school based asthma programs in Rochester, NY. We used linear regression and multivariate analyses to compare asthma outcomes for children whose caregivers did and did not report AR.
Results
We used data from 1,029 children with asthma (mean age 7.4, 60.4% Black, 29.5% Hispanic, 72.8% insured with Medicaid). 63% of children reported AR. Children with AR had significantly fewer symptom free days over 2 weeks compared to children without AR (7.2 vs. 8.3, p < 0.001). Children with AR also had more daytime symptoms, (4.7 vs. 3.7, p < 0.001), more rescue medication use (4.5 vs. 3.4, p < 0.01), and more activity limitation due to asthma (3.6 vs. 2.5, p < 0.001). Only 44% of children with AR reported allergy medication use.
Conclusions
Among a large school-based cohort of minoritized children with asthma, we found that the majority of children have comorbid allergic rhinitis, which was associated with increased asthma morbidity. Inadequate recognition and treatment for allergic rhinitis likely represents substantial preventable morbidity for this group.
