Methods: Data from the National Asthma Survey were analyzed to compare asthma control in children (5 to 11 yrs) using ICS/LABA vs. ICS alone. Both short term (symptoms within last 2 weeks, day and night symptoms in last 30 days and use of systemic glucocorticoids in last 3 months) and long term (asthma attack, emergency department visits, hospitalizations and activity limitations in the prior year) outcomes were compared. Demographics, availability of health insurance, indoor allergen exposure and asthma education were compared between the two groups. Asthma control in an adult population (18 to 44 years) was also assessed for the same parameters.
Results: 69 children using ICS/LABA and 134 using ICS alone were identified. Baseline characteristics were similar in both groups. 67% of children were using ICS/LABA for more than 6 months. There were no differences in short and long term asthma outcomes between the two groups (p>0.05 for all outcome measures). Similar results were obtained with the adult population. (p>0.05 for all outcome measures).
Conclusions: These data indicate that asthma control in children, using ICS/LABA vs ICS alone, was not different than asthma control using similar medications in the adult population. LABA tolerance or the use of ICS/LABA in subjects with more severe asthma could explain these findings.
