Asthma medication use and disease burden in children in a primary care population.

Background: Children with persistent asthma underuse controller medications and overuse relievers. A better understanding of the appropriateness of regimens, medication adherence, and adequacy of asthma control is needed.

Objectives: To describe use of asthma medications and disease burden in children with persistent asthma, to determine whether use of controllers and relievers is consistent with national guidelines, and to estimate adequacy of asthma control.

Parent-reported environmental exposures and environmental control measures for children with asthma.

Background: Mounting evidence suggests that indoor allergens and irritants contribute to childhood asthma. National asthma guidelines highlight the importance of their reduction as part of comprehensive asthma treatment.

Objectives: To assess the prevalence of potential environmental triggers, to identify risk factors for such exposures, and to determine whether prior parental education about trigger avoidance is associated with fewer such exposures.
