Follow-up

The Iwate Tohoku Medical Megabank Organization (IMM) will ask participants about their health over an extended period of time.

This is known as a “follow-up.” The follow-up will be conducted based on consent forms obtained from participants at the baseline survey.

Schedule for the TMM Community-based Cohort Study

1. Questionnaire Survey by mail

An annual survey will ask participants about topics such as their lifestyle, treatment status, illness, and mental health.

2. Incidence of cancer, stroke, and heart disease

The IMM is reviewing medical charts at hospitals to identify the incidence of cancer, stroke, and heart disease in conjunction with the Iwate Cancer Registry and the Iwate Stroke Registry and the Northern Iwate Heart Disease Registry Consortium.

3. Death, migration, health check-up data, medical claims data, data of the long-term care insurance, and causes of death

Information about death, migration, health check-up data, medical claims data, data of the long-term care insurance, and causes of death of participants will be collected with the cooperation of municipal governments and relevant organizations.

 A follow-up system will be instituted with municipal governments and relevant organizations. In addition, the system under which the study is conducted will be made more reliable and secure to protect personal information.

4. Second health survey

 Since 2017, a second health survey has been conducted.

Results of the second health survey will be compared to those of the baseline survey. Those findings should help to improve health and prevent illness in the future.

 Information obtained from participants should reveal an association between genomic information and lifestyle and the future development of illness. That information can also help to someday implement personalized prevention and personalized medicine.

Participants in the baseline survey will be informed about the second health survey in order of the year of their participation.
