PREVALENCE OF CHILDHOOD ASTHMA AND ALLERGIC DISEASES IN ANKARA, TURKEY

The first epidemiologic survey of the prevalence of childhood asthma a nd other allergic disease in Ankara, Turkey, was done in May 1992. A q uestionnaire on factors influencing the atopic status and allergic sym ptoms was distributed to parents of 1226 children aged 6-12 years. In this questionnaire, parents were asked to give information about physi cian-diagnosed asthma and atopic dermatitis (AD), and self-reported wh eezing and rhinoconjunctivitis (perennial or seasonal). The overall re sponse rate was 85% and included 502 boys (48.5%) and 534 girls (51.5% ). The lifetime prevalences of asthma, wheezing, rhinoconjunctivitis, and AD were 17.4%, 23.3%, 28%, and 6.1%, respectively, and the reporte d prevalences for the last 12 months were 8.3%, 11.9%, 15.4%, and 4%, respectively. Asthma and other allergic disease had been recognized in 23.2% of the children during the last year; in half of these, more th an one disease was present. Eight percent of the families kept pet ani mals; 95.4% of children had been breast-fed, of whom 61% for more than 6 months; and at least one person smoked at home in the case of 73.9% of children. Some health insurance was available to 72.8% of the fami lies. Cumulative prevalences of wheezing, rhinoconjunctivitis, and AD were significantly associated with the presence of pets, passive smoki ng at home, and absence of health insurance. The prevalence of asthma was not affected by any of these factors except atopic family history. In conclusion, asthma and other allergic diseases constitute a major health problem for schoolchildren in Ankara.
