Symptoms, wheeze or shortness of breath in past week; nocturnal, woken by asthma in past week; activities, activities limited by asthma in past week; missed school, missed school days due to asthma in last year; Oral Steroids, reported oral corticosteroids in the previous 12 months
ORs represent multivariable associations between a given characteristic and secondary outcomes adjusted for the other covariates in the table, as well as for asthma controller medication use.
Composite Socioeconomic Index: derived from reported maternal education attainment level, annual household income, and insurance status. Odds Ratio reported is for each unit decrease in the index.
Maternal education categorized into low (less than high school graduate), medium (high school graduate), and high (some college or higher)
Low Income: Odds ratio displayed represents the odds of going from a high income to a low income
Public: government subsidized insurance with care through community-based clinics; Public-Closed HN: government subsidized insurance with care through closed health network; Closed HN = closed health network
Model also adjusted for asthma control in addition to the covariates listed in table.
