Evaluation of the prevalence of atopic diseases by ISAAC surveys in the primary school children of Sivas

Abstract

Aim. During the past few decades, The International Study of Asthma and Allergies in Childhood (ISAAC) questionnaires have shown that the prevalence of childhood asthma and allergy is increasing worldwide. The aim of this cross-sectional study was to determine the change in prevalence and risk factors of asthma, allergic rhinitis, and eczema from two ISAAC questionnaire based surveys conducted on two groups of schoolchildren in Sivas, a central Anatolian city, during the years 1997 and 2005. Methods. The study populations of the two comparable cross-sectional surveys were comprised of schoolchildren aged 6-14. The sample size in 1997 and 2005 were 569 and 2978 children, respectively. Results. This study showed that the prevalence of asthma, allergic rhinitis and atopic eczema increased significantly from 9.7 % to 11.8%, 5.4% to 10.2%, and 3% to 10.1%, respectively. Risk factor analysis revealed that living with a dog or cat, body mass index (BMI), and family history of atopy were associated with higher risk of asthma (p<0.05). Conclusion. In the 8-year period from 1997 to 2005, the prevalence of asthma, allergic rhinitis, and eczema has increased significantly in our region. Further studies with larger number of patients are required to investigate the factors causing this increased local rate.

“…tarafından ISAAC protokolü ile yapılan epidemiyolojik araştırmada astım prevalansı %6,9, atopi varlığı %20,6 olarak bulunmuştur (11) . Normal populasyonda yapılan diğer çalışmalarda da, astım sıklığı sırasıyla %11,8, %6,9, %4, %17,8, olarak saptanmıştır (12)(13)(14)(15) . İzmir'de 1992-93 yıllarında Karaman ve ark.…”

“…Doktora bu yakınmayla başvurunun seyrek olması alerjik rinit sıklığının daha az saptanmış olmasına neden olabileceği düşünülmüştür. Ülkemizde ISAAC anketi ile yapılan diğer çalışmalarda ise alerjik rinit sıklığı sırasıyla %6,3 ile 17,6 arasında olarak bulunmuştur (12,14,16,20) .…”
