Summary
This study evaluates the effects of adding on an environmental home intervention to standard asthma medication management on controller medication requirements among children and adolescents with asthma. The investigators hypothesize that the addition of an individually-tailored, multi-faceted Environmental Control Strategy (ECS) to guidelines-based controller medication will result in less controller medication requirement and allergic inflammation than controller medication alone among urban asthmatic children.
