Background of Study

The incidence of chronic disease such as cancer, myocardial infarction, stroke, etc., which are major factors of death of the Japanese before their average life expectancy (2008: 79 years for males and 86 years for females), or causes for lowering the quality of life, is deeply related to lifestyle habits such as eating habits, exercise, smoking, alcohol drinking, etc., and by improving the lifestyle habits, it is believed that these diseases can be prevented, to some extent, before they occur. However, data on the Japanese population are not sufficient as to what type of meals are good or what is the appropriate amount of alcohol to drink.

Study objective

This study is being conducted to determine what lifestyle habits are relevant to the incidence of diseases, by collecting information about lifestyle habits from approximately 100,000 people living in various parts of Japan, and performing a long-term follow-up of over 10 years regarding the development of their diseases.
