A school-based sample of 6335 participants in the 2007 survey and 6441 participants in the 2013 survey was the study population.Results: The response rates in 2007 and 2013 were 62.08% and 52.97% respectively.The physician-diagnosed allergic rhinitis was 11.6% (n=413) in 2007 and 11.1% (n=380) in 2013, so it remained stable. There is an increase in 12-month prevalence of allergic rhinitis from 14.9% (n=530) to 23.3% (n=796) and cumulative allergic rhinitis from 26.5% (n=943) to 34.5% (n=1176). The prevalence of all diagnosed allergic diseases decreased between 2007 (34%; n=1212) and 2013 (15.5%; n=510). The prevalence of eczema and the prevalence of food allergy increased from 10.2% to 15.4%, from 4.8% to 6.2%. The prevalence of asthma and physician-diagnosed allergic rhinitis decreased from 6.2% to 5.7% and from 11.6% to 11.1%.Family history of atopy (p<0.001), frequent upper airway infection (p<0,001), antibiotics given in the first year of life (p<0.001), living in a weedy area (p<0.001), were all significant risk factors of allergic rhinitis symptoms in both studies.By comparingour two surveys we observe that cumulative allergic rhinitis, 12-month prevalence of allergic rhinitis, and from the diagnosed allergic diseases eczema and food allergy have become increasingly prevalent.The prevalence of all diagnosed allergic diseases decreased.
