It is generally believed that the excellent body conditions are parallel to the strength of phisique and also to the resistance toword diseases. Therefore, bulky man has his vital force much stronger than the average and poor people has.
It may be sure that bulky man is more healthy than the average manduring some period of his life, but it has to be understood these healthy conditions are hold by himself temporarily, but it cannot be the index of health through his lifetime.
The author collected 578 males aged from 44 years old to 57 years in 1957. Data of their body measurements are listed in their school health records and reserved in their school. The files of resords contain the results body examination in each school year during their school ages.
Whether they are alive or not in 1957 are questioned to themselves, their relatives, their schoolmates
& classmates, local officers at theirresidences, and their parmanent domicile family record books.
Among 578, at the time of survey, 464 are secured to notify still alive, 39 are dead by war, 71 by disease, 2 by suicide, and 3 by accidents.
Main findings are as follows:
1. At six years of age, the body structure height, weight, chest length, and Rohrer index, and their longevity are not related so high, but attwelve years old, it is significant that the overweighted boys show poorer longevitythan the average and under average.
2. And also the body growth from six to twelve is related to theirlongevity. The rapid growth means the short longevity.
The coefficient of correlation between body measurements at eleven years of age and that of adult's, is about plus 0.75. Therefore the general findings from life insurance company on the overweighted adult and thir risk to die each year, may be expected to be extended back to their school ages. The main findings of this survey support this speculation
