Reproductive History

A full reproductive history for all mothers in the DNBC has been established by Helene Kirkegaard (MHSc, PhD) using data from the Danish Medial Birth Registry, The National Patient Registry, and The Legally Induced Abortion Registry.

The data file contains information on 91.383 mothers in the DNBC with 100.415 unique pregnancies (lbgravnr). For all twins, triplets, and quadruplets only one of the children is kept in the file.

The information available on the reproductive history goes from 1973 to July 2011 (for births) and August 2013 (for abortions).
