Since 2014, the Helmholtz Centre for Infection Research (HZI) has been examining National Cohort participants at the Study Center in the CRC Hannover. Germany’s largest nationwide population study is intended to provide information that will facilitate the discovery, treatment, and prevention of widespread health problems such as cardiovascular diseases, cancer, diabetes, dementia, and infections. HZI researchers are also studying infectious diseases and immune system disorders at the CRC Hannover.

The German National Cohort at the Hannover Study Center

A total of 10,000 participants from the greater Hannover area will be examined and interviewed at the Hannover Study Center. They are being randomly selected from the government database of registered residents. Selected individuals receive a personal letter containing detailed information on the study. Each participant then spends about three or four hours undergoing a variety of examinations performed by specially trained, experienced medical personnel.


The study participants will subsequently be tracked over a period of up to 20 years, during which quite a few of them will develop diseases. It will then be possible to link these with the previously collected data. Consequently, the study provides unique opportunities to conduct a wide range of scientific examinations with the potential to facilitate early detection, prevention, and treatment of widespread conditions such as cardiovascular diseases, cancer, diabetes, dementia, and infections.

The study is being funded by the German Federal Ministry for Education and Research, the Helmholtz Association of German Research Centers, and state governments.
