This study analyzed demographic disparities in the utilization of inhaled corticosteroids (ICS) among patients with persistent asthma using data from the National Asthma Survey. The results showed that over half of patients did not use ICS. African Americans and uninsured patients had significantly lower odds of using ICS compared to whites and insured patients respectively. Multivariate analysis controlling for demographic factors found that African Americans had lower odds than whites of using ICS, potentially due to lack of access to care and inconsistencies in treatment guidelines. Insurance status was also a significant predictor of ICS use, with insured patients having higher odds of use.
