*Abbreviations:**OR* Odds ratio, *CI* Confidence interval, *FU1* first follow-up at the ages of 10.8 years (girls) and 11.8 years (boys), *FU2* second follow-up at the age of 12.8 years (both genders); Likelihood-ratio-p refers
to exposure only.

^{a)}Adjusted for gender, birth weight z-score adjusted for gestational age, being firstborn,
Caesarean section, maternal smoking during pregnancy, gestational age in weeks, maternal
age, maternal body mass index (kg/m^{2}) and maternal asthma;

^{b)}After backward stepwise selection from fully adjusted model with p ≤ 0.05; all final
analyses include the covariates gender and maternal asthma as default.

^{c)}High level allergic sensitization = Sum of specific IgE > 3.9 *kU/l;* the 25 percentile of sensitized children.

^{d)}Adjusted for gender, maternal smoking during pregnancy, gestational age in weeks and
maternal asthma. No significant interaction effects were found in final analyses.
