Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study was an update and amplification of exposure measurements of the EPIC-Potsdam Study, which started in 1994-1998.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The sub-study was conducted in the German Institute of Human Nutrition according to an approved study protocol.

The study program included comprehensive surveys on diet and lifestyle (smoking, physical activity, and anthropometry). The aim was to achieve repeated measurements in a sub-cohort of about 600 people to validate (measurement error correction) and calibrate (adjustment of insufficient data collected to the actual data location) existing baseline data in the entire cohort (EPIC-Potsdam cohort).

To this end, within age groups and by gender, active EPIC participants were then randomly selected in the years 2009 to 2012 from the cohort, contacted and invited to re-visit the respective study center. 816 subjects were acquired for re-examination, participation rate was 56.4%.

Each participant gave informed consent. The study protocol has been approved by the Ethics Committee of the Medical Association of the State of Brandenburg, Cottbus, on 18/12/2009.
