HELIX Cohort

The HELIX cohort represents a collaborative study across six established and ongoing longitudinal population-based birth cohort studies in six European countries (France, Greece, Lithuania, Norway, Spain, and the United Kingdom).

HELIX collected data from 1,663 mother-child pairs recruited during pregnancy. Data was retroactively collected and harmonized for the pregnancy period, and biomarkers, omics signatures and child health outcomes were measured at ages 6-11 years.

A second follow-up visit was conducted at ages 12-18 years with 867 adolescents participating where biomarkers, omics signatures and health outcomes were again collected.
