This report is the statistical studies on the 376 cases of childhood asthma which were collected from the hospital belonging to the commitee. Six hundreds and thirty-seven cases of non-allergic children whose age and sex were about same as asthmatic children were used as control group. 1) Number of the boys were 2.8 times as many as the girls. 2) There was no difference on number of brothers and sisters between both groups. There was no such tendency that asthma used to develope in the small number of brothers. 3) The cases which had asthma or other allergic disorders in their family were 80% in the asthma group and 50% in the control group. 4) The asthma attacks started 20% in age of one, 17% in age of two, 19% in age of three, 10% in age of four, 9% in age of five and 8% in age of six, therefore majority cases of asthma started in the early age. Compared with the age of the first attack between the cases of which family had asthma patients and the cases of which family had no asthma patients, there was no difference between both groups. There was no such a tendency that asthma develops in the earlier age among the cases of which family has asthma patients. 5) Causes of the first asthma attack were not clear in about a half of the cases and common cold in 37%, pneumonia in 3.2%, measeles in 2.7%, pertussis in 2.1%, bronchitis in 1.1% and dust, severe cold whether, typhoon, parenteral injections, fatigue and psycotic factors in less 1%. 6) Asthma attacks developed in fall in 70%, in rainy season in 30%, in spring in 27%, in winter in 25% and in summer in 15%. 7) According to the statement of parents, the main causes of asthmatic attacks were common cold and meterological factors such as severe cold weather, typhoon, high humidity and cold front were important. Fifty-five cases of 376 (15%) developed with special foods and inhalents. 8) The cases which had suffered from eczema during infacy were 67% in asthmatic group, beside 22% in control group, therefore cases of asthma group had a tendency developing eczema three times as mach than control group, therefore cases of asthma group during infancy was same as that of control group. Eczema developed in same ratio among breast fed, artificially fed and mixed fed infants. There was no obvious fact that asthma and eczema observed more frequently artificially fed infants. 9) There was evidently more cases which had a tendency to catch frequent colds in asthma group than in control group. 10) Cyclic vomiting occured equally 10% in both groups. 11) The cases which were diagnosed as asthmatic bronchitis during infancy were 37% in asthma group and 7% in the control group.
