Abstract: Objectives: To assess the time trends and possible risk factors associated with allergic rhinitis symptoms in schoolchildren from Denizli, Turkey.<br />Method: Two identical cross-sectional surveys were performed in the 13- to 14-yr age group at intervals of six years using ISAAC questionnaire. Possible risk factors were also asked and the children completed questionnaires by self.<br />Results: A total of 4078 children (response rate 75%) in the 2008 and 3004 children (response rate, 93.8%) in 2002 were included. The lifetime prevalence of rhinitis, 12-month prevalence of rhinitis, prevalence of associated itchy eye in the previous 12 months and doctor diagnosed allergic rhinitis prevalence were increased from 34.2% to 49.4% (POR=1.87, 95% CI=47.8-50.9 and p ≤ 0.001), from 23.5.0% to 32.9% (POR=1.59, 95% CI=31.4-34.3 and p ≤ 0.001), from 9.6% to 14.9% (POR=1.64, 95% CI=13.8-16.0 and p ≤ 0.001), and from 4.3% to 7% (POR=1.67, 95% CI=6.2-7.8 and p ≤ 0.001) respectively. Severe interference with daily activity in the previous 12 months did not change. In multivariate analysis, history of family atopy, stuffed toys, high annual family income, presence of allergy in mother, father and accompaniment of children to their parents after school hours in textile industry were found as risk factors in 2008 study.<br />Conclusion: The prevalence of allergic rhinitis increased significantly in 2008.
