Research Activities

We investigated the relationship between information on older people living in the community prior to the earthquake and the causes of death due to the tsunami. We also examined the medium-term risk of death after the earthquake when the living environment changes. It was inferred that people with severe depression tendencies need to be recognized as high-risk people who will delay evacuation in the event of a disaster. In addition, interaction with friends is thought to reduce the risk of death after a disaster.

Our team, in cooperation with Miyagi Prefecture, has continued to survey the health status of residents in temporary housing since the disaster as part of its support for disaster victims, and has now clarified the trends in health status.
Although the percentage of people in poor health is decreasing as a whole, many people in public disaster housing, where many elderly people live, have a poor subjective sense of health, and it is necessary to continue building communities where residents can maintain and improve their health through social participation.
