MedicalResearch.com: What is the background for this study? What are the main findings?
Response: Observational studies have limitations in their ability to examine disparities in asthma, as these studies have relied on self-reported measures of medication use, asthma diagnosis, severity, outcomes, and access to care.
Using data collected from a randomized controlled trial, we found that subjects with lower income had a significantly higher number of asthma treatment failures and asthma exacerbations, independent of race, BMI, education, perceived stress, baseline lung function, hospitalizations, inhaled corticosteroid adherence, inhaled corticosteroid dose, environmental allergen sensitization, and second-hand smoke exposure.
