French Longitudinal Study from Childhood.
Elfe logo

ELFE is the first French longitudinal cohort on a national scale devoted to the follow-up of children, which addresses the multiple aspects of their lives from the perspective of social sciences, health, and the environment.

For the first time, researchers from all walks of life are following the history of children from birth to adulthood.

Key elements

  • 18,300 children followed
  • Since 2011
  • For 20 years

Objectives of the cohorte

More than 18,000 children born in metropolitan France in 2011 were enrolled in the study, which represents one in every 50 children born in 2011. The observation of children born in the same period, over a period of twenty years, represents a unique opportunity to better understand what influences their development and how they find their place in society.

The ELFE study mobilizes more than 150 researchers from many scientific disciplines. Those researchers are interested in the health of children, their schooling, their diet, their family and social life and their environment. Cross-referencing these multiple pieces of information makes all the scientific richness of the ELFE study.
