i-Share (Internet-based Students HeAlth Research Enterprise) is a new open and prospective cohort on university students’ health. Participants are registered in the first years of study initially with the Universities of Bordeaux and Versailles-Saint-Quentin many many other French universities are now participating. Students are followed up with yearly assessments.

The study sets 2 main types of objectives:

1. Evaluate the frequency and impact of several diseases that may have immediate or short-term consequences on health and well-being (e.g. stress and depression, migraine, sexually transmitted infectious diseases, etc.).
2. Biomedical research objectives on the determinants of diseases. We have set up a cerebral MRI study and biobank on a sample of about 2000 participants including DNA and RNA.
