Background: Predictive models have rarely been used in allergy research and practice. However, they might support physicians in advising patients. Objective: The aim of this study was to create predictive models for the incidence and persistence of allergic rhinitis (AR) during adolescence. Methods: A prospective population-based cohort study was conducted starting at age 9 to 11 years. Potential risk factors for atopic diseases obtained at baseline in 2810 subjects were used to create predictive logistic regression models for the incidence and persistence of physician-diagnosed AR with current symptoms at age 15 to 18 years. Results: Positive skin prick test responses to outdoor allergens at baseline were the most important determinant for both the incidence and persistence of AR until follow-up. For the incidence of AR, positive skin prick test responses to indoor allergens, parental history of asthma, female sex, and not having been breast-fed exclusively for 2 or more months were additional statistically significant independent risk factors. Depending on the number of risk factors present, the probability of the incidence of AR increased from 2% (no risk factors present) to 72% (full model; 95% CI, 58% to 85%). The probability of persistence of AR ranged from 33% (no risk factors present) to 83% (full model; 95% CI, 70% to 97%). Conclusion: The course of AR over puberty can be predicted using risk factors that are easy to determine in childhood. Sensitization to outdoor allergens seems to play a much greater role for disease development than sensitization to indoor allergens. This might help pediatricians in advising patients.
