Part 1. Body Structure
8,237 Korean boys and girls ranging in age from 6 to 13 years were classified into three groups according to their past and present nutritional conditions, and measurements were taken with the following results:
1) The average height of a well nourished group was markedly taller than that of a poorly nourished group. This difference has been concluded to come from the difference in the length of the leg rather than from the difference in the sitting height.
2) No significant differences were found between the group of good nutrition and that of poor nutrition in the girths of the chest, the head, the hack, the upper arm, the wrist and the girth of the ancle, but the girth of ´the waist seemed tQ be larger in poorly nourished children than in well nourished children.
3) Of various: differences in value indicating nutritional condition, difference in stature is due to the difference in the length of the lower limb. This may be inferred from measurement values´ of Korean urban and rural children in the past, and values derived as the result of comparison between the physiques of Korean children and American children.
Part 2. Nutritional Indices
Investigation was made of the past and present nutritional conditions of 8,237 school children ranging in age from 6 to 13 years. These children were classified into three groups according to the findings of the investigation, and their nutritional indices were examined based on the values of %body- measurement with the following results.
1) Indices based on height and weight are not useful because malnutrition affects not only weight but also height. Of the various indices, only Broca index was found to be useful.
2) Of indices based on height and the lengths of other parts of the body, the relative leg index is as a nutritional index more useful than the relative sitting height.
3) The relative girths of the chest, the head and the hack have no meaning as a nutritional index, but the relative girth of the waist is a useful nutritional index.
4) Of comperative values between the length of the upper and lower limbs, and the girth of each specific part of them, the relative girth of ancle is useful as a nutritional index.
5) Indices based on height, weight and the girth of the upper limb seem to have no meaning.
