学童の体位の過大現象よりみた一将来像について

抄録

Studies on physical growth have been carried out from various angles so far so as to predict the physical standard of the nation. Most of the reports on these studies are based on a mean value of growth over a particular period. The author has observed for five years the growth of school children who have shown a greater value of growth, and come to the conclusion that we may be able to predict the physical standard of the future nation with reference to the above-mentioned reports if there are no particular characteristics in the growth process in this group of children and their physical form. In 38 year of showa (1963), we selectel about 2, 500 boys and girls from the sixth grade in 23 ku's (wards) of Tokyo who were more than +2 above the national mean value in both height and weight, and have compaved their growth processes and physical form, etc., with the mean values of standard children in Tokyo and the rest of the country. By this investigation we have obtained the following results. 1) The group of children who are generally called overgrown children does not indicate an abnormal process of growth, nor are the exceptions. 2) The body of Japanese people in the future will probably develop both in weight and in length of legs. 3) The growth value of the investigated children is considered to be the mean value of children between the year 1990 and 2000, if the present environment does not regress but progresses to a certain extent.
