The Effect of Nursing Patterns on the Development of Allergic Disorders

영유아기 식이가 알레르기질환 발생에 미치는 영향

Allergic disorders may be defined as the abnormal reactions to proteins. Cow milk is the first foreign protein which the human being would contact postnatally. Serveral studies suggested that this contact had certain effects on the development o allergic disorders with great controlversies. Seven hundred seventy eight students from middle class in Seoul, aged 6 to 17 wears, were surveyed to delineate the relationshpis between the cow's milk contacts in infancy and the subsequent development of allergic disorders in Koran population. Questionaire were included the nursing patterns in infancy, the past medical history of asthma or wheezy bronchitis and the presence of infantile eczema. Skin tests to three common resporatory allergens in Korea(house dust, house dust mite; D. farinae, D. ptoeronssinus) were performed. The positivity was determined by the wheal size larger than that to histamine. 70.2% of whole mateials was fed by breast milk, 13.1% by cow's milk and 16.7% by mixed nutsing. From the obsevation of nursing patterns by (table 2), we find that the number of breast milk group has been decreasing in 1970's. 10.1% of breast milk group(BMG) had wheezy bronchitis, 8.8% of cow's milk group(CMG) and 11.5% of mixed nursing group(MNG). Infantile eczema history was positive in 27.8% of BMG, in 26.5% of CMG and in 29% of MNG. Skin test positivity was 23.8% in BMG, 25.5% in CMG and 26.2% in MNG. There prevalences of allergic disorders in each nursing group did not reveal any statistically significant differences. In conclusion, nursing patterns in infancy do not seem to have certain effects on the development of allergic disorders such as infantile eczema. wheezv bronchitis or skin test positivity.
