Effect of Socio-Economic Status on Quality of Life in People Affected with Respiratory Allergy

In the present study we investigated the impact of respiratory allergy on quality of life in young people, and examined whether socio-economic status modifies the above dependence. The study was conducted in 458 female and 363 male university students, aged 18-25. Information on socio-economic status (SES) was collected using a questionnaire. The occurrence of allergy was determined on the basis of answers to the questions whether the allergy and specific allergens were medically diagnosed. Quality of life (QoL) was based on the Polish version of the SF-36 test. Respiratory allergy or respiratory and food allergy were declared by 19.2 % of women and 19.0 % of men. The prevalence of allergy was higher in students with high SES. The students suffering from allergy obtained lower scores in all domains of QoL, but the differences were statistically insignificant. However, the overall test result in allergic students was significantly lower than that in non-allergic students. Differences QoL were significantly associated with socio-economic variables. In persons with low SES, the differences in QoL between those suffering from allergy and those who did not have allergy were larger than in persons with high SES. The results indicate that the course of allergic diseases is highly dependent on socio-economic status. The prevalence of allergy among students of low status is lower than among those of high status. However, allergy to a greater extent impairs the quality of life of students with low than high SES.
