Brief summary

ATHLETE will set up a prospective Europe-wide exposome cohort covering the first 2 decades of the life course, which will integrate data on the external, chemical, physical,behavioral, and social domains of the exposome, as well as on health outcomes and biological omics responses, from preconception until adolescence. As part of ATHLETE, the investigators will follow up a unique existing exposome cohort into adolescence (the HELIX Subcohort).
