    Abstract:
    BACKGROUND: There is growing evidence that the prevalence rates of asthma and allergic diseases are increasing, especially among children. Several risk factors are under investigation. OBJECTIVE: To evaluate the prevalence and risk factors for allergic diseases, including allergic rhinitis (AR) and atopic eczema (AE), among 13- to 14-year-old schoolchildren in Israel. METHODS: A modified version of the International Study of Asthma and Allergies in Childhood written questionnaire was administered to a national sample of schoolchildren 13 to 14 years old in Israel. The questionnaire was completed by the schoolchildren themselves. RESULTS: There were 10,057 complete questionnaires available for analysis. The prevalence of AR symptoms ever and current AR were 41.6% and 9.4%, respectively. Allergic rhinoconjunctivitis symptoms ever were reported by 15.8% of the children. The prevalence rates of 6 months of itchy rash ever and AE were 5.9% and 7.8%, respectively. After adjustment for demographic and environmental factors, current asthma, parental history of asthma, and population group were the most significant risk factors for current AR (odds ratio [OR], 4.47; 95% confidence interval [CI], 3.70-5.40; OR, 1.30; 95% CI, 1.02-1.66; and OR, 1.75; 95% CI 1.45-2.13; respectively) and AE (OR, 2.30; 95% CI, 1.80-2.90; OR, 1.80; 95% CI, 1.40-2.30; and OR, 1.70; 95% CI, 1.40-2.00; respectively). CONCLUSIONS: Israeli children have a low prevalence rate of current AR and a midrange rate of AE. Arabs have lower prevalence rates of allergic diseases than Jews, and the prominent risk factors for those diseases are current asthma and parental history of asthma.
