Public Health Lab
Machine-translated · View original
A public health lab that uses epidemiological methods to explore the causes of disease and healthy life expectancy.

AboutAbout the lab
From the causes of disease to longer healthy life expectancy.
The lab uses epidemiological methods to clarify the causes of disease, and conducts research that points to measures leading to longer healthy life expectancy.
In the professor's greeting, it is stated that the lab has not stopped at identifying the causes of many diseases, but has also shown the effectiveness of cancer screening and measures for extending healthy life expectancy, and has achieved their implementation in society.
The same greeting states that in recent years it has become possible to conduct epidemiological studies that take into account genetic factors, detailed lifelogs, and various metabolites.
The lab can analyze the large-scale cohort data it has built up over the years, as well as the data being collected through the Tohoku Medical Megabank Project.
