Juvenile-onset diabetes has been assumed to be rare in this country, mainly based on clinical impression of the pediatricians who have been treating diabetes mellitus. The incidence, however, has not been surveyed extensively. The reports which can be based upon for the estimation of actual incidence have been very few.
2740 questionnaires were sent to departments of pediatrics and internal medicine of larger hopsitals and clinics, concerning the number, name, sex, present age and address of juvenile onset diabetics.
Juvenile onset diabetics were reported from almost all prefectural areas without any special tendency.
310 cases were estimated to be under 15 years of age. Based on the estimation of the present number of children under 15 years of age, about 25 millions, reported incidence of juvenile onset diabetes is calculated to be 1.2 per 100, 000. Although actual incidence, which is presumed to be considerably higher than the present figure, can not be determined, the figure calculated from this survey appears to support the clinical impression that juvenile onset diabetes mellitus is actually rare in Japan compared with Western countries.
In contrast to the maturity onset diabetics, among which males outnumber females like in most other Asiatic countries, there are more females among juvenile-onset diabetics. The reason for this phenomenon is not yet clear.
More detailed informations were obtained concerning initial symptoms, growth and treatment from 266 patients. Almost all of them are insulin-aependent diabetics with polydipsia, polyuria and weight loss as the initial symptoms. They were not necessarily tall or obeses before the onset, and tend to remain somewhat smaller than normal boys and girls of the same age and sex. Girls tend to become obese afterpuberty. About one third of the children have experienced coma or acidosis.
It is hoped that the incidence and feature of juvenile diabetics in this country is more precisely revealed, leading to the better care of this conaition in near future.
