The modern society of the 21st century has to cope with many psychosomatic disorders which have high significance in public health. Several researches pointed out that one of the most determinant aspects in connection with asthma bronchiale is the mother-child relation. The aim of this study was to detect what is the predisposing role of early childhood attachment factors. 130 children with asthma bronchiale between the age of 10 to 18 and their mothers were involved. A socio-demographic questionnaire (to detect the early experiences), the Multidimensional Anxiety Scale (for the children) and the Beck Anxiety Inventory (for the parents) were used. Our most important finding is that out of important life events in connection with childhood attachment (especially the breastfeeding and its length) was proven to be a protective factor. Establishing preventive opportunities at institutions are recommended, e.g. setting up educative and preventive groups for chronically ill children and their parents. Attachment in early childhood must be considered to be even more important in the case of chronically ill patients.
