Until recently, most studies report an increasing prevalence of allergy and asthma. The research suggests that the increase may have to do with changes in lifestyle and living conditions. This study seeks to determine the prevalence and changes in allergic diseases in relation to socioeconomic status (SES) 6 years apart. The research material consisted of data collected in two cross-sectional surveys conducted among university female students in 2009 and 2015 (respectively, 702 and 1305 subjects). The surveys evaluated the incidence of allergic conditions and socio-economic status. The occurrence of allergy was determined on the basis of answers to the questions whether the allergy and specific allergens were defined on the basis of medical work-up. The prevalence of allergic diseases increased from 14.0% to 22.3% over a 6-year period. In both cohorts, allergic diseases were more prevalent among females with high SES than with low SES. In 2009, significant differences were noted in relation to urbanization of the place of living and the number of siblings. In 2015, all socioeconomics factors significantly bore on the prevalence of allergy.
