Gravidity, Parity

hey guys have a doubt regarding gravidity and parity..if a primipara mom gives birth to a set of twins, would her gravidity be G1 or G2?

I think, U should be asking primigravida women, not primipara.

nulligravida = has never become pregnant.
primigravida = it is her first pregnancy
nulliparous = never given birth (irrespective of primigravida or nulligravida)
primipara = given birth once

If it is primigravida and has given birth to twins, then G1 P2.

If it is primipara (already gave birth once), has given birth to twins ,then G2 P3. Here it is her 2nd pregnancy irrespective of one fetus,twins or triplets,hence G2. I said P3 assuming she first delivered single fetus and surely she delivered twins in 2nd delivery.

Parity can be divided into 4 sub-categories :
1st #. Full term Pregnancies (38-42 weeks)
2nd#. Pre-term Pregnancies
3rd#. Abortions (spontaneous or elective abortion)
4th#. Total number of living children.

Thus the above women has 6 pregnancies(G6), 2 full term,1 pre term,2 abortions, 4 living children (P2124).

yeh..thats quiet obvious..the order is full term, preterm, abortions, living children. what i meant to ask is, if the mother has been gravid 6 times, and of them 2 were aborted, one resulted in preterm birth and 2 in full term birth, how do you account for 4 living children while her gravidity is 6.
