Current asthma: ever having an asthma diagnosis plus wheezing in the past year or taking asthma medications in the past month; no asthma: no asthma: no wheezing and no use of asthma medications or wheezing in the past 12 months; AR: ever having a diagnosis of hay fever or AR; no AR: never having a diagnosis of hay fever or AR; aeroallergen IgE; having any aeroallergen IgE >0.35 IU·mL−1; no aeroallergen IgE: IgE≤0.35 IU·mL−1. #: adjusted for sex and current age and height; : model 1 additionally adjusted for race/ethnicity, maternal education and smoking during pregnancy, median value owner-occupied housing and percent≥bachelor's degree (census tract, mid-childhood), and household income and any smokers at home at early teen visit; +: reference group is <20 ppb.
