Talk:Gravida/para/abortus

Gravidity is the number of times a woman was pregnant, whether she deliverd or not, including the present pregnancy. Parity is the number of times a woman has come to term and/or delivered a baby. A four digit system is used to describe this: G0P0000.

The first digit is the number of times the woman came to term. It does not matter when the patient delivered or how far pregnant she was when she delivered. The second digit is the number of premature babies the woman had. The third digit is the number of abortions, miscarriages, or ectopic pregnancies. The fourth digit is the number of living children the woman has now.

Therefore, P1001 is a woman who has given birth once and has one living child. P1002 is a woman who has given birth once and has two living children (twins). P2001 is a woman who has delivered twice but now only has one living child (it may have died after childbirth or when it was 20 years old). A gravida 2 Para 1 is a woman who is pregnant now and has had one child.
