Collection and usage attributes

Guide for use:

A pregnancy resulting in multiple births should be counted as once pregnancy.

In multiple pregnancies with more than one type of outcome, the pregnancies should be recorded in the following order:

  • all live births
  • stillbirth
  • spontaneous abortion
  • induced abortion
  • ectopic pregnancy

Where the outcome was one stillbirth and one live birth, count as stillbirth.

If a previous pregnancy was a hydatidiform mole, code as spontaneous or induced abortion (or rarely, ectopic pregnancy), depending on the outcome.


The number of previous pregnancies is an important component of the woman's reproductive history. Parity may be a risk factor for adverse maternal and perinatal outcomes.
