    The Prevalence and Risk Factors of Allergies in Turkey (PARFAIT) study was planned to evaluate the prevalence of and risk factors for asthma and allergic diseases in Turkey. The present analysis used data from 25,843 parents of primary school children, obtained from a cross-sectional questionnaire-based study. A total of 25,843 questionnaires from 14 centres were evaluated. In rural areas, the prevalences asthma, wheezing, allergic rhinitis and eczema in males were: 8.5% (95% confidence interval (CI) 7.9-9.1%), 13.5% (95% Cl 12.8-14.2%), 17.5% (95% Cl 16.7-18.2%) and 10.8% (95% Cl 10.2-11.4%), respectively; and in females were: 11.2% (95% Cl 10.9-11.8%), 14.7% (95% Cl 14.3-15.1%), 21.2% (95% Cl 20.4-22.0%) and 13.1% (95% Cl 12.4-13.8%), respectively. In urban areas, the corresponding prevalences in males were: 6.2% (95% Cl 5.8-6.6%), 10.8% (95% Cl 10.3-11.3%), 11.7% (95% Cl 11.4-12.0%) and 6.6% (95% Cl 6.2-7.0%), respectively; and in females were: 7.5% (95% Cl 7.9-7.1%), 12.0% (95% Cl 11.7-12.3%), 17.0% (95% Cl 16.4-17.6%) and 7.3% (95% Cl 6.9-7.7%), respectively. Having an atopic first-degree relative or any other atopic diseases had significant effects on the prevalence of allergic diseases. Housing conditions, such as living in a shanty-type house, visible moulds at home and use of wood or biomass as heating or cooking material were associated with one or more allergic diseases. Although genetic susceptibility is strongly associated, country- and population-based environmental factors may contribute to increased prevalence rates of allergic diseases.

    Prevalence and risk factors of allergies in Turkey: Results of a multicentric cross-sectional study in children
    Kurt, E; Metintas, S; Basyigit, I; Bulut, I; Coskun, E; Dabak, S; Deveci, F; Fidan, F; Kaynar, H; Uzaslan, EK; Onbasi, K; Ozkurt, S; Pasaoglu, G; Sahan, S; Sahin, U; Oguzulgen, K; Yildiz, F; Mungan, D; Yorgancioglu, A; Gemicioglu, B; Kalyoncu, AF
    The Prevalence And Risk Factors of Allergies in Turkey (PARFAIT) study was planned to evaluate prevalence and risk factors of asthma and allergic diseases and also to find out which geographical variables and/or climatic conditions play a role determining the prevalence of allergic diseases in Turkish school children. Study was planned as cross-sectional questionnaire-based. About 25,843 questionnaires from 14 centers were appropriate for analysis. Parental history of allergy, having an atopic sibling and other atopic disease in index case was significant risk factors for all allergic diseases. Breast feeding decreased the risk of current asthma (OR: 0.92, CI: 0.86-0.99) and wheezing (OR: 0.93, CI: 0.87-0.99) but not allergic rhinitis and eczema. Respiratory infection in the past was an important risk factor for the occurrence of allergic diseases especially for asthma which was increased 4.53-fold. Children exposed to household smoke were significantly at higher risk of asthma, wheezing, and allergic rhinitis (OR: 1.20, CI: 1.08-1.33; OR: 1.21, CI: 1.09-1.34; and OR: 1.32, CI: 1.21-1.43, respectively). All allergic diseases were increased in those children living in areas which have altitude of below 1000 m and mean yearly atmospheric pressure above 1000 mb. The study has suggested that household and country-specific environmental factors are associated with asthma, wheezing, allergic rhinitis, and eczema risk during childhood in Turkey.
