Please allow me to repeat the lecture I give on the regular now so everyone here can also serve as an advocate to educate our colleagues who go around calling a P1 a ‘Nullip’ and other egregious Gravidity/Parity errors.
1. Let’s talk Latin for a second.
‘Nullus’ means ‘none’.
‘Primus’ means ‘first’.
‘Multus’ refers to there being more than one.
‘Parous’ refers to the bearing of offspring.
‘Gravid’ refers to the state of pregnancy.
2. This means that:
– ‘Nullipara’ (Nullip) = No deliveries before
– ‘Primipara’ (Primip) = Single delivery before
– ‘Multipara’ (Multip) = More than one delivery before
– ‘Nulligravida’ = No pregnancies before
– ‘Primigravida’ = In their first pregnancy
– ‘Multigravida’ = In their 2nd or more pregnancy
3. Important examples:
– a G1P0 is a Nullipara and a Primigravida.
– a G10P0 is also a Nullipara, but a Multigravida.
– a G2P1 is a Primipara but also a Multigravida
– a G5P4 is a Multipara and a Multigravida
– a P0+0 is a Nullipara and a Nulligravida
Bonus Information: everything that comes after the plus sign occurred before the age of viability and has no bearing on the parity of a woman.

Gravidity is the number of times a woman has been pregnant. Another term used to describe gravidity is gravida. When you are trying to determine the gravidity, keep the following in mind:
- The outcome of each pregnancy(meaning…did the baby live or did the mom lose the baby?) is not relevant. So in other words, if the baby lived or did NOT we still count this as a pregnancy.
- The current pregnancy is included in the count. Don’t let this confuse you when you are answering test questions…always make sure you count the current pregnancy (if she is pregnant) with the other past pregnancies.
- Multiple babies? We’re not counting the number of babies BUT just the pregnancy itself. Therefore, if the woman is pregnant with twins, triplets, quadruplets etc., the gravida is just ONE.
Parity is the number of times a woman hasbirthed or completed a pregnancy (meaning the baby is no longer inside mom’s body) at 20 weeks gestation or greater. When you are trying to determine the parity, keep the following in mind:
- The count includes babies born alive or stillborn at 20 weeks gestation or greater.
- Multiple babies? Just like with gravidity, we’re not counting the number of babies born/birthed. Therefore, if a mom completes a pregnancy at 20 weeks gestation or greater with twins, triplets, quadruplets etc., the parity is just ONE.
Now, for each term you need to be very familiar with their individual terms. If you look at them below you can tell that their prefixes (nulligravida vs nullipara) are the same BUT their suffixes are different. Therefore, if you know the meaning of each prefix and the correct definition of the suffix, determining the meaning of each word is easy.
- Nulli: never or none
- Primi: first
- Multi: many
Terms to Know:
- Nullipara: a woman has never completed a pregnancy at 20 weeks gestation or greater.
- Nulligravida: a woman has never been pregnant.
- Primipara: a woman has only once completed a pregnancy at 20 weeks or greater.
- Primigravida: a woman has been pregnant once or is currently pregnant for the first time.
- Multipara: a woman has completed two or more pregnancies at 20 weeks gestation or greater.
- Multigravida: a woman has been pregnant two or more times.
Gravida and Parity Examples (Scenarios)
Example 1: During the health history collection on a female patient at a women’s health clinic visit, the patient tells you she is not currently pregnant but has been pregnant three times before. She states that at 39 weeks gestation she gave birth to a boy. However, the other two pregnancies ended at 7 and 10 weeks gestation. How would you calculate the patient’s gravidity and parity?
Answer: Gravida 3, Para 1
Rationale: The patient is NOT currently pregnant so we won’t count this in the gravida. However, she has been pregnant three times before. So, her gravida is THREE. The patient further explains that she has only completed ONE pregnancy at 39 weeks and the other two were completed at 7 and 10 weeks gestation. Remember parity is the number of pregnancies completed at 20 weeks gestation or more. Therefore, the patient’s parity is 1.
Example 2: A patient is pregnant with twins at 30 weeks gestation. This is her first pregnancy. How would you calculate the patient’s gravidity and parity?
Answer: Gravida 1, Para 0
Rationale: This is the patient’s FIRST pregnancy. Therefore, gravida is ONE (remember that the number of babies is NOT added to the gravidity). She is still pregnant and has not completed the pregnancy yet. Therefore, the parity is ZERO.
*However, let’s say she gives birth at 38 weeks gestation to twins. What would the gravidity and parity be now? Gravida 1, Para 1 (the parity changes since she has now completed the pregnancy…again the para ISN’T two because we don’t calculate the number of babies).
