On June 1, 2024, over 1,000 children from the EDEN cohort and their parents were invited to take part in the new iEDEN follow-up phase. This new project focuses on the effects of the use of screens and digital technologies on the physical and mental health of adolescents and young adults.

Adolescence is a critical period in development, and more generally in the life course, as it can influence behavior and future health. However, the current era is quite unique in that today’s teenagers are growing up in a society characterized by the massive development of digital technologies. This project will therefore help to better understand the use of these tools, their determinants (demographic, social, etc.) and their impact on physical and mental health.

It will draw on the extensive data collected in the EDEN cohort, as well as on new data collection. Scheduled to run for a year, participants will be invited to complete questionnaires and tests on a web platform (parents) and a smartphone application (children), the latter collecting information on their smartphone use over the course of a week. Information on screen use is at the heart of the project, but data on puberty, sexuality and exposure to radio frequencies will also be collected.
