Predictive factors for the development of bronchial asthma by the age of 3

Abstract

The relationship between several factors at 1.5 years of age and the development of bronchial asthma by 3 years of age was investigated. The factors that were found to be related to the development of bronchial asthma were identified and listed as predictive factors for the development of bronchial asthma by the age of 3. As a result, a parent or a sibling with bronchial asthma, a history of wheezing with common cold or exercise, positivities for specific IgE antibodies to mites or house dust, and DNA polymorphisms for the AA allele in ADRβ2 R16G, are important predictive factors for the development of bronchial asthma by 3 years of age.
