[Respiratory and skin diseases among school children in the industrial and rural regions].

The studies were done among the school-children in 3 grammar schools (2 in the industrial and 1 in rural regions). Allergological examination (anamnesis, physical exam and skin prick tests with inhalants) were performed among the pupils suspected of the allergic disorders on the basis of the questionnaire analysis made in all school-children. The results were compared to the environmental air pollution in the school region. The frequency (4.9-7%) and the type of the allergic diseases were similar in all 3 schools. The most frequent allergens were pollen, mites and animal epithelia. In rural region familial predisposition to allergy was 2 times higher in pupils suffering from allergy. 70% of pupils suffering from allergy in the industrial regions had no familial predisposition to allergy.
