The ELFE (Étude Longitudinale Française depuis l’Enfance) Study is a nationally representative, multidisciplinary birth cohort of infants born to 18,040 women in 349 maternity hospitals in France in 2011. The protocol, design and recruitment procedures of the ELFE survey have been previously described (Vandentorren and Pirus 2006). Participating mothers and infants were recruited while in the maternity units and subsequently monitored. Exclusion criteria were: stillbirth, birth before 33 weeks gestation, multiple births and plans to leave metropolitan France within three years. Mothers had to be able to give informed consent in one of the study languages (French, English, Arabic and Turkish).

Maternity data was collected using standardized interviews by trained interviewers and self-completed questionnaires. Information on obstetric characteristics was collected from maternal recalls and medical records. Two months after delivery, data was collected via telephone interviews.

Information is collected annually and then every two years up to the age of 20, in the form of questionnaires (at home or by telephone), biological samples (at birth, three and six years), environmental measurements and follow-up logbooks (standardized collections of anthropometric measurements, etc.). The medical data is relayed by the parents from health records and completed by a medical examination at two years and a health check-up at six years.
