Methods This was a cross sectional study including a sample of children with 9 to 11 years of age, recruited from 40 randomly selected schools in Lisbon. The ISAAC phase II questionnaire, completed by caregivers, was used to collect data. It included questions on symptoms (wheezing, rhinitis and eczema), use of treatments and health services. Rhinitis ever was defined as the presence, ever, of at least one nasal symptom (sneezing, runny or blocked nose), in the absence of respiratory infection; CR was defined by the presence of rhinitis ever and at least one nasal symptom in the previous 12 months; if CR was accompanied by itchywatery eyes it was considered that the child had CRC.
