  • *OR adjusted for the following confounders: gender, high BMI, parental history of allergic diseases, parental education, parental ethnic origin, place of residence, day care outside home, breastfeeding and passive smoking. Analyses include only factors that had a p value ≤0.2 in the univariate analyses.

  • †Only significant risk factors are shown in this logistic regression model.

  • –, No significant associations were found for the listed risk factors; aOR, adjusted OR; AR, allergic rhinitis; BMI, body mass index; EIA, exercise-induced asthma; SPT, skin-prick test.
