| Outline of Final Research Achievements |
To prevent metabolic syndrome, cardiac diseases, stroke and cancer, it is important to know the true usual amounts of certain nutrients in each individual’s diet; however, the true values are never available. Similarly, administrators and researchers never know the true proportion of the people who are at high risk for nutritional excesses in any given region. The aim of this project was to develop a statistical method to identify the individuals and proportion of individuals at high risk of nutritional excesses.
A statistical methodology for determining the individuals and proportion at a high risk of nutritional excesses has comprised mathematical models. My computer program that uses this methodology has been applied to nationwide Japanese nutritional data. The results of this project have been published in an overseas journal and will be utilised by domestic and foreign authorities.
