About this study

The goal of this clinical trial is to learn if adding Air Quality Index (AQI) information to asthma action plans works to improve asthma outcomes in children. It will also learn about children with asthma who report being more sensitive to outdoor air pollution. The main questions it aims to answer are: * Does adding either information about the EPA-AQI or commercial AQI improve asthma outcomes over time? * Are there changes in nasal gene expression in children with asthma who report they are more sensitive to outdoor air pollution? Researchers will compare EPA-AQI and the commercial-AQI groups to a control group to either AQI works to improve asthma. Participants will: * Receive standardized outdoor air pollution education and an asthma action plan * Provide nose and blood specimens * Have visits every 4 weeks for 48 weeks, 10 will be conducted by telephone calls and 3 visits will be in person.

Interventions

Behavioral: EPA-AQI — The EPA-AQI group will receive standardized outdoor air pollution education, standardized AQI education, instructions for AQI usage, and an asthma action plan containing information specific for the EPA-AQI, and will demonstrate the ability to navigate to the EPA-AQI via smartphone app or website.
Behavioral: Commerical-AQI — The commercial-AQI group will receive standardized AQI education, instructions for commercial-AQI usage, and an asthma action plan containing information specific for the commercial-AQI, and will demonstrate the ability to navigate to the commercial-AQI via smartphone or website.
Behavioral: Education and plan — Standardized outdoor air pollution education and standard asthma action plan

Primary outcomes

Change in asthma control scores, over-time, between groups (Baseline through 48 weeks, measured at 4 week intervals)

Eligibility information

Inclusion Criteria: * A healthcare provider diagnosis of persistent asthma (Steps 2-5 as defined by US guidelines) or intermittent asthma (Step 1) + at least one severe asthma exacerbation (defined by American Thoracic Society (ATS)/European Respiratory Society (ERS) criteria as requiring at least 3 days of systemic steroids or an Emergency Department/Urgent Care visit requiring systemic steroids) in the prior 12 months * Home access to a smartphone or internet * Primary residence in Allegheny County, PA * One participant per household * Age 8 -17 years * Healthcare provider evaluation for asthma in the prior year Exclusion Criteria: * Diagnosis of other active chronic respiratory diseases (e.g., cystic fibrosis, bronchopulmonary dysplasia, etc.) * Neuromuscular disorder * Chronic disorder limiting independent ambulation (e.g., spastic quadriplegia, etc.) * Cyanotic heart disease * Plans to relocate from Allegheny County, PA in the next year (12 months) * Use of intranasal or oral/intramuscular/intravenous corticosteroids 4 weeks prior to randomization * Current participation in another asthma intervention trial
