with a particular focus on the Metabolic Syndrome which make it obiligatory for person aged 40 through 74 to reduce medical expenses and prevent lifestylerelated diseases. However, Kondo 2004 indicates a lack of foundation for health checkup. And we think that it is important to clarify foundation for effect of health checkups and healthcare advice. In this paper, through consistent statistical data analysis, we suggested a method which evaluate directed effect, attempting to figure the doctor's charactor, based on results of the health checkups carried out in April, 2004. As a result, we confirmed that the doctor classified subjects in the directed group from their body types such as weight and BMI, and in directed effect that it reduced weight and BMI, but it gave increase of TG and decrease of HDL which were likely to develop abnormal lipid metabolism. So, we found that adequate evaluation for effect of healthcare advice after careful consideration about the doctor's charactor leads to suggestion of scientific foundation for health checkups and healthcare advice.
