Main Areas and Themes of Research

1) Main Areas

The aim of our research is to prevent people suffering from diseases and to promote their health. In order to achieve these goals, we investigate the relationship between genetic factors and environmental factors of diseases. We can promote primary prevention to elucidate this relationship. On the other hand, there are several confounding factors in humans, so that experimental methods including cell culture are used to clarify the role of physiologically active factors.

2) Main Themes
  1. Trends in disease statistics at the workplace
  2. Diagnostic value of ECG tests in health examination
  3. Biological monitoring for workers engaged in hazardous work
  4. Early detection of alcohol dependency using blood examination
  5. Effect of vitamin K2 intake for bone turnover
  6. Relationship between serotonin transporter gene polymorphism and depressed mood caused by job stress
  7. Association between estrogen receptor α(ERα) polymorphisms and equol production, and its relation to bone mass
  8. Effect of isoflavone aglycone on bone turnover

Clinical Features

In our school, the Department of Public Health belongs to clinical medicine. Our main duties in relation to hospital work are health checkups and vaccination. Professor Katsuyama also holds an additional post as an occupational health physician at Kawasaki Gakuen.

Educational Features

1) The principle of education

Japanese laws on medicine define the duty of doctors: "Doctors contribute to promote public health through medical care and health guidance; thereafter, they are to secure a healthy life for people." It is therefore obvious that students in medical school need to appreciate the concept of public health.

To summarize, the field of public health is considered the science that consists of diagnosis and treatment, as well as clinical medicine. However, the subjects of public health comprise groups of many people who have various levels of health status, and approaches to these individuals are different from those of clinical medicine. Thus, public health practitioners utilize the techniques of other fields, as well as medicine, i.e., statistics, social science, economy, etc. This is why the field of public health is called the interdisciplinary science. In our school, lectures concerning public health are held at the time when students possess much knowledge. We educate students of the importance of public health, its present status, the problems of public health in our country, etc.
