Perinatal data collection

Recruitment period

This study included all births (livebirths, stillbirths, and terminations of pregnancy) that occured from 22 to the end of 34 weeks of gestation, from March 28 to December 31, 2011, after the families were informed.

We adapted the recruitment period to the term at birth so that we would have enough cases of each of the different types of preterm births to be able to reach statistically valid conclusions.

  • 8 months of recruitment for the extremely preterm infants (born before the end of the 6th month of pregnancy, between 22 and 26 completed weeks of gestation), born between March 28 and December 31, 2011.
  • 6 months of recruitment for the very preterm infants (born before the end of the 7th month, between 27 and 31 completed weeks), born between March 28 and October 30, 2011.
  • 5 weeks of recruitment for the moderately preterm infants (born at the beginning of the 8th month, between 32 and 34 completed weeks), born between May 2 and June 5, 2011.

This study began on March 28, 2011, in 7 French regions (Alsace, Burgundy, French Guyana, Languedoc-Roussillon, Limousin, Midi-Pyrénées, and Rhône-Alpes) and on May 2, 2011, in the 18 other regions (Aquitaine, Auvergne, Basse-Normandie, Bretagne, Centre, Champagne-Ardenne, Franche-Comté, Haute-Normandie, Ile-de-France, Lorraine, Nord-Pas-de-Calais, PACA-Corsica, the Loire River region, Picardie, Martinique, Reunion, and Guadeloupe).

A group of children born at term will be also folllowed up at the same time. These children come from the ELFE cohort, also launched in 2011, with the objective of following more than 18 000 children for 20 years.
 

Number of subjects

Term at birth and date of birth made 8417 children eligible for Epipage 2. 93% of families agreed to participate in this first stage of data collection and 7804 children were therefore finally included.

Data Collected and Methods of Collection

During this period, several types of data were collected:

  • About the mother:
    • From the medical file, about her pregnancy (complications, treatments) and delivery
    • During an interview to learn about her environment and her experience of this birth
    • By a self-completed questionnaire about her health status before the child's discharge.
  • About the child: from the medical file, about the child's health status at birth and its course during hospitalization (principal complications, treatments, food, medical management, and more).
  • About the organization of care specific for preterm babies:
    • By the collection, from the maternity units and neonatology departments, of information describing the medical practices used to care for mothers and babies. These data make it possible to take into account more accurately the specificity of the departments and their role in the results observed in the children.
    • Through the collection of information from the perinatal health networks of each region to improve our understanding of the variations between the regions in their care for women and children.
