BACKGROUND
The aim of the present study is to determine the prevalence of allergic diseases and related risk factors in Izmir, Turkey, and to assess the positive immunoglobulin E (IgE) levels against common allergens.


METHODS
The questionnaires were completed via face-to-face interview with a total of 2937 individuals. Specific IgE was studied in the serum samples by enzyme-linked immunosorbent assay (ELISA). This cross-sectional population-based study comprised adolescents over the age of 15 years and adults of Izmir province.


RESULTS
In Izmir, the prevalence of self-reported allergy was 35.5%. Allergy was statistically significantly more common in females, university graduates, in those with high income, with family history for allergy, aged 40-49 years, those living in a flat, keeping pet(s), and in those using central heating. The prevalence of atopy according to the serum IgE levels (Class 3 with any of 3 IgEs) was found 1.6%.


CONCLUSIONS
In conclusion, the prevalence of atopy was found lower in Izmir as compared to the results of other studies.
