The German government has launched the largest long-term health research project in the country's history, involving 200,000 people and 18 research centres.
The aim is to find out more about genetic, environmental and social influences on health. The participants, from across Germany, will be tracked for 20 years to help researchers understand common diseases such as diabetes, dementia, cancer and cardiovascular diseases.
This should, in turn, help to improve treatments and disease prevention in Germany’s public health system.
