title: A new formula for summarising the pregnancy history.
abstract: Pregnancy history formulae usually provide only summaries of numbers of pregnancies and births. Different pregnancy outcomes and their sequence are not captured. A new pregnancy history formula is proposed where one number provides information on parity, gravidity, sequence, gestation and outcome of pregnancies. For instance, 914 represents the history of a woman having had three pregnancies, where '9' represents a term first birth, '1', a miscarriage and '4', a preterm perinatal death in the third pregnancy. This formula could be used in medical records or perinatal databases.
