The data of the "Elfe" study is now available to all public and private research teams, French or foreign, on the basis of a research project and under the conditions specified in the Data Access charter.

The French Longitudinal Study since childhood (Elfe), funded as Investissements d’Avenir, opens its database to the entire scientific community.

Elfe is a cohort of 18,300 children recruited at birth in 2011 to follow up adulthood. Its purpose is to study the determinants of development, health, socialization and educational pathways of children. At each stage of recruitment and follow-up, the research teams associated with the study benefit from exclusive access to a period of 18 months from the availability of data. This period is now over and the maternity survey data are now made available to the entire scientific community. The survey on maternity includes an interview with the mother, a self-questionnaire on lifestyle and diet during pregnancy and a statement of obstetrical and medical history of the child. Requests for access to data are made through a secure internet online platform offering the necessary documentation on the investigation and databases. Obtaining them is subject to the authorization of the CNIL. More information about the study and how to access the data.
