speaks about the organization and results of the Elfe study
Demographer, researcher at INED and member of the Elfe team since 2010, he took part in the organization and evaluation of surveys in maternity units. He is in charge of partnerships with associations and administrations, in particular regarding access to health insurance data.
(Interview from December 2012).
What was the role of the people who worked for Elfe in 2011?
The project team at INED, which included nearly twenty people
from various disciplines, had to be expanded for the launch of the
national cohort. To do this, we recruited around thirty health
professionals who were charged with coordinating survey deployment
in different regions. They established agreements with 320
maternity units and trained a thousand interviewers, midwives for
the most part, who approached mothers who were about to give birth.
The services of the INED General Secretary also provided a great
deal of support.
How many children are in the cohort?
Thanks to a massive communications campaign, we succeeded in
bringing more than 18,000 infants into the cohort. The second
challenge is to maintain a relationship of trust with parents so
that as many as possible agree to be interviewed repeatedly as
their child grows up. After a first telephone interview when the
child reaches the age of two months, the parents are contacted
again on the child’s first birthday. So far, very few families (2%)
have asked to leave the cohort. The number of interviews to be
carried out is almost double the number of infants in the cohort
because the mother and, if possible, the father are both
How are the surveys financed?
The preparation and the first steps of the survey were financed
by the institutions that are backing the project and by a
government grant for large research infrastructure needs. To
continue, we needed more resources. We have just received funding
for the next eight years under the Ministry of Research’s Equipex
programme. Nonetheless, we will need to flesh out our budget with
other resources so that we can approach the families in ways other
than by telephone: a home visit when the child is 3, and a medical
examination around the age of 8.
How can the data be accessed?
The research teams involved in creating the questionnaires over
the last few years have an 18-month exclusivity period. The first
set of data will be available to them in early 2013. The Elfe
research group is not a closed one, however. A new call for
proposals in the social sciences will be launched in 2012. It will
provide opportunities to work on new issues that, we hope, will
interest INED researchers. Possible themes include the families’
financial situations and their impact on the child’s socialization
and development; the choice of first name and surname; the
emergence of difficulties in school, cognitive dysfunctions, and
disabilities; and patterns of health care seeking.
Where can participants find information on the progress of the project?
Besides the website, the families receive an information
bulletin each year that informs them about the initial study
findings and the next steps. The researchers communicate with each
other using an intranet and receive a newsletter containing
detailed project information, notably on the experiences of the
