In the previous report, the author has presented his finding which indicated the general trend of the improvement in physical growth among primary and middle school children in Sendai in post-war days, and discussed whether this acceleration of growth is general or is limited to a part in these groups.
In the present study, similar investigation was undertaken with primary, middle and highschool children in Miyagi Prefecture and in many other parts of Japan.
The results showed that the growth in body length in the young population may be said to beimproved in a general way in the recent years, but the growth of body weight and chest girth have not been so expedited generally, remaining as low as ever in the subjects with low grade of development.
Such an acceleration of physical growth in the different ages, when viewed in the light of total age of growth, seems to present a picture of general precocity.
