Japan is one of the countries where health check is fully arranged. One purpose of health check is to change health behavior into healthier one and to improve health condition. Public nurses or medical doctors often help this change by proper guidance.
But we have not so much evidence that change of health behavior cause to improve health condition in quality or in quantity.
Now Japanese Government is practicing a five-year project from 2008 to 2012. This project aims for decrease in the risk of occurrence of cardiovascular disease or diabetes for metabolic syndrome patients or the candidates. I hope that much evidence will be made by this national project.
The purpose of medical examination for cancer detection is to cause decrease in mortality rate by cancer, improve of quality of life and decrease in medical cost. It is a pity that we have not so much reliable evidence which secure the effect of the examination. All prefectures have cancer registry in Japan. It is necessary that we utilize this registry to make reliable evidence.
The Japanese Society of Health Evaluation and Promotion must fulfill the role to make evidence for effects of change of health behavior and for effects of medical examination for cancer detection. I propose the society have a committee to play the role and many organizations for health check in whole countries cooperate with the committee to make evidence.
