This paper is to prove how closely bone mineral density, body formation, and nutrient intake are connected with each other. Some important problems like calcium intake at an early age are also to be discussed so that we can get a new perspective regarding nutrition education. I pointed out in my previous report that the group of young women who needed care owing to their low bone density measured by calcaneus accounted for 13%. Our concern about this trend is considerable when our country faces an aged society. In this investigation, I divided the subjects into four groups according to the average of bone mineral density and then went on to the analysis of the data obtained from comparing higher value groups with lower ones from the view points of calcium intake and body formation. I found the results of the analysis was quite satisfying in that : 1. The average bone density value of all the subjects was 2.6±0.18(ΣGS/D), which was almost the same with the national average of 20-year-old women. The groups having lower values (-1 standard deviation) made up 26% of the whole. 2. The average of the subjects' height and weight was slightly higher than the national average. 3. The overall average of BMI was 20.9±2.32,which was within the normal range. The students whose BMI were less than 20 accounted for 30%, with the smallest BMI being 16.5,the largest one 31.2,and CV 11%. As for their slenderness and fatness, the subjects were widely distributed. 4. The students seemed not to take in the required quantity of such nutrition as Energy (kj) and calcium. 5. Configuration ratio of calcium intake by food groups was as follows : milk and milk products comprised 26-32%, vegetables and fruits 20-24%, beans 8-11%. The ratio of taking in beans were lower than the national average. 6. The subjects are lower than the national average in all the items of exercise load added test and physical test except wink-power.
