Basic description

• Main aim of cohort
  This cohort with ongoing recruitment was initiated to create a data resource for research on the fetal programming hypothesis, and on various aspects of pregnancy, birth, and neonatal care. The cohort has detailed information on obstetric characteristics and procedures, as well as on neonatal care. The cohort also contains information on lifestyle and environmental exposures of the pregnant women. Two sub-cohorts deserve mentioning: (1) Approximately 8,000 children born in the main cohort during 1990-1992 were followed by questionnaires at the age of 9-11 years. (2) The Aarhus Children’s Biobank was embedded in the cohort in 2008 and more than 6,500 families (mother, father and child) has donated bio-samples, including more than 3,000 cord blood samples. For more information on these sub-cohorts, please contact the principal investigator.
  
  Recruited number of:
