Several studies note that bronchial hyperresponsiveness has increased in the past years. There is a connection between allergen exposition during childhood and the development of asthma bronchiale. 1988 a questionnaire was sent to the parents of 281 Viennese school children. The children were tested for bronchial hyperresponsiveness as well as for sensitization to airborne allergens like Alternaria alternata (A. alternat) and Dermatophagoides pteronyssinus (D. pter.). The same test with the same methodology was repeated in 390 children at the same school in 1997. In the period from 1988 to 1997 the number of children with bronchial hyperresponsiveness increased significantly from 20 to 27 percent. The prevalence of sensitization increased from 24 to 34 percent. The report of asthmatic symptoms and allergic reactions is increasing as well.
