Abstract

The prevalence of atopic dermatitis has significantly increased in developed countries during the past several decades. Surveys performed in Hungary also show a growing number of atopic dermatitis (AD) cases, although, a carefully designed case-controlled studies have not been performed. Therefore, we investigated the prevalence of AD in individuals under 19 years of age within the agricultural area of East-Hungary. Combined data obtained with Schultz-Larsen questionnaire on 1158 children were analyzed, and 25% of the index persons were examined by dermatologist. The mean prevalence of AD determined by questionnaires appeared to be 17.5% in the entire study population. Result of dermatological examination verified the validity and sensitivity of the questionnaire. A negative correlation was found between the severity of the disease and the length of breast feeding period. (Spearman's correlation coefficient = − 0.2247, p = 0.034). The prevalence of AD in an East-Hungarian agricultural area is nearly as high as that reported for populations residing in industrially developed countries, with a higher prevalence during childhood. Data suggest that premature abruption of breast feeding maybe one of the major factors among other environmental factors that is contributing to the development of AD.
