All percentages were weighted for sampling proportions. Self-reported income data were missing for 16 participants; race, for 10; and parental educational level, for 3. Medicaid and CHIP income limits are for children and adolescents aged 6 to 18 years.
Children were coded as having received combination asthma medications if the parent reported use of a combination asthma medication (eg, inhaled corticosteroid plus long-acting β-agonist) and/or concurrent use of multiple controller medications (eg, inhaled corticosteroid and leukotriene modifier).
