This indicates 5 pregnancies, with 3 live births, 1 preterm birth, 1 induced abortion or miscarriage, and 3 living children. A woman who had 4 pregnancies, one of which was miscarried, is noted as G 4P 3A 1.Īnother system may be used to provide information about the number of miscarriages, preterm births, and live births by dropping the "A" and including four separate numbers after the "P", as in G 5P 3113. Therefore, the history of a woman who has had two pregnancies (both of which resulted in live births) would be noted as G 2P 2. The abortus term is sometimes dropped when no pregnancies have been lost. Abortus is the number of pregnancies that were lost for any reason, including induced abortions or miscarriages. Pregnancies consisting of multiples, such as twins or triplets, count as ONE birth for the purpose of this notation. Para indicates the number of viable (>20 wks) births. A current pregnancy, if any, is included in this count. Gravida indicates the total number of times a woman has been pregnant, regardless of whether these pregnancies were carried to term. They can be used to guide a practitoner's monitoring of a woman's current or future pregnancies.Gravida/para/abortus (GPA), or sometimes just gravida/para (GP), is a shorthand notation for a woman's obstetric history. If a woman has not had an abortion, the A is simply left out.Īn obstetric history serves as a history of a woman's past pregnancies and their outcomes. So this calculator follows that convention.
G2P2A0, it's common practice to just write G2P2. For example, if a woman has had 2 pregnancies and 2 live births, instead of writing, If a woman has not had any abortions, then it's common practice to leave out abortions in the "G P A" format. The obstetric history will then be automatically calculated and displayed. To use this calculator, a user simply enters in the number of pregnancies that a woman has had, the number of live births she's had, and the number of abortions she's had, and clicks the 'Calculate' button. One pregnancy and an abortion in another, she would have an obstetric history of G2P1A1. If a woman has been pregnant twice and had a live birth in If the fetus dies after 20 weeks into the pregnancy, it is considered a stillbirth. The abortions is the number of pregnancies that have been terminated (induced abortion) or the number of pregnancies in which the fetus dies in utero before 20 weeks into the The child must be delivered after 20 weeks to be viable and be considered a live birth (parity). A viable pregnancy cannot be performed before 20 weeks, so Because fetuses are only viable when born after 20 weeks, the child must be born after 20 weeks. So don't be confused with multiple gestation pregnancies. Thus, if a woman hasīeen pregnant once and gave birth to triplets, she has a gravidity of 1 and a parity of 1 (G1P1).
If a woman has had a successful pregnant with either 1 child, 2 children, 3 children, etc, the parity is 1 for that pregnancy. Gives births to twins, triplets, or any other multiples.
It is important to distinguish that the number of live births per pregnancy can only be 1. So parity includes live health births as well as stillbirths, which is when the baby dies in uteroĪfter 20 weeks into the pregnancy. The parity is the number of live births and stillbirths that a woman has had. If a woman has been pregnant 3 times, her gravidity is 3 (G3). The gravidity is the number of times a woman has been pregnant. Based on this, the calculator formulates the obstetric history in a "G P A" format, where G is the gravidity, P is the parity, and She had (parity), and the fetus deaths in utero she has had (abortions). The GPA system obstetric history taking calculator calculates the obstetric history of a woman in terms of the number of times she has been pregnant (gravidity), the number of live births
