Gravida/para/abortus

Gravida/para/abortus (GPA) encodes a summary of a woman's obstetric history.


 * Gravida: the number of pregnancies a woman has had.  A current pregnancy, if any, is included.
 * Para: the number of pregnancies resulting in live births.  Twins and larger multiples count as one parity.
 * Abortus: the number of lost pregnancies, including abortions and miscarriages.

GPA gives a quick overview of a female's obstetric history. G3, P2, A1 indicates three pregnancies, two live births, and one loss. G3, P2, A0 indicates three pregnancies (one ongoing) and two live births.
