Abstract
Japanese population is 128 million, and the population of younger than 15 years old is less than elderly people at least 65 years old. Then, Japanese population pyramid is distorted. While the population under 65 years old has reduced, the population 65 years old and above have increased. Japanese major health insurance society has reported that lifestyle-related medical costs are about 1,791 billion yen in fiscal medical expenses total about 1,184 billion yen. It becomes about 15 % of the total. This is a great amount of costs which is able to be ignored. Therefore, we analyzed the relation between the medical expense and food intakes by a regression model, and the results have been reported in InMed-14. In addition, we have analyzed the relation between the numbers of outpatient and food intakes in five years by a regression model. It is because lifestyle is made by continuing food intakes. Although we have obtained the results by these analyzes, however we need to analyze the relationships between factors.Therefore, in this paper, we analyze the relation between these factors by a principal component analysis.
