 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
