In the UK, gravidity is defined as the number of times that a woman has been pregnant and parity is defined as the number of times that she has given birth to a fetus with a gestational age of 24 weeks or more, regardless of whether the child was born alive or was stillborn. For example, a woman who is described as 'gravida 2, para 2 (sometimes abbreviated to G2 P2) has had two pregnancies and two deliveries after 24 weeks, and a woman who is described as 'gravida 2, para 0' (G2 P0) has had two pregnancies, neither of which survived to a gestational age of 24 weeks. If they are both currently pregnant again, these women would have the obstetric résumé of G3 P2 and G3 P0 respectively. Sometimes a suffix is added to indicate the number of miscarriages or terminations a woman has had. So if the second woman had had two miscarriages, it could be annotated G3 P0+2.

Accompanied by Arabic numbers, G, P, and A (or Ab) describe the patient’s obstetric history. Roman numerals are not used. Separate GPA sections by commas. Alternatively, spell out the terms in lower case.
Obstetric history: G4, P3, A1 or gravida 4, para 3, abortus 1. ***When one or more of the numbers is 0, the preferred form is to write out the terms: gravida 2, para 0, abortus 2***.
• G: gravida (number of pregnancies)
• P: para (number of births of viable offspring)
• A or Ab: abortus (abortions)
• nulligravida gravida 0: no pregnancies
• primigravida gravida 1, G1: 1 pregnancy
• secundigravida gravida 2, G2: 2 pregnancies
• nullipara para: 0 offspring
