Biobank Based on the i-Share Student Cohort

The i-Share cohort was set up to study various important aspects of students' health and to better understand early mechanisms contributing to the occurrence of common diseases representing an important public health burden. The i-Share cohort is funded by an "investment for the future grant" from the French National Research Agency (ANR-10-COHO-05-01) with the aim to recruit 30000 students at the University of Bordeaux, and a few additional partner universities in France and abroad (www.i-share.fr).

The bio-Share study is a biological repository embedded within the i-Share study, aiming at collecting blood samples (for genetic analyses as well as measurement of other biomarkers) from a subset of 2000 i-Share participants volunteering for this ancillary project.

The goal is to set up a platform that will enable investigators in the future to study biological determinants of conditions that affect young adults and to test certain hypotheses on the pathophysiology and mechanisms underlying diseases occurring both at a young age and later in life (as early exposures may also impact late onset diseases).

The biobank will comprise the following biological materials: plasma, serum, whole blood, red blood cells, DNA, RNA. Levels of fasting glucose and lipid levels (total cholesterol, HDL-cholesterol, LDL-cholesterol, triglycerides) will be returned to participants.
