Outline of Final Research Achievements

As an empirical analysis, we used the medical service history data (Recept Data of National Health Insurance and Specific Medical Examination Result) of Izumi City, Osaka Prefecture, from FY2011 to FY2016, and data of the exercise instruction program in the period. From the specific medical examination data, the health condition type was extracted by the self-organizing map, and the major disease name and medical cost for each type were obtained using the recept data, and the disease risk etc. of each type was clarified. In addition, as a result of considering the change in health condition type during the 6 years, it is suggested that medical expenses and rates of treatment accepter of the types corresponding to metabolic syndrome is larger than the other types, and that the exercise instruction program contribute to improving health condition. We also studied development of self-organizing map by maximum likelihood method.
