From the Research

Yes, parity counts if a fetus was viable but was aborted after 20 weeks of gestation, as parity refers to the number of pregnancies that have reached viability, regardless of whether the pregnancy resulted in a live birth or not 1. This is important for medical documentation and obstetric history because pregnancies that reach viability can have physiological effects on a woman's body and may influence future pregnancy outcomes.

When documenting obstetric history using the GTPAL system (Gravidity, Term births, Preterm births, Abortions, Living children), such a case would be counted under "P" for parity and also under "A" for abortion. Healthcare providers need this information to accurately assess obstetric risk factors and provide appropriate care in subsequent pregnancies. The most recent study on pregnancy options counseling highlights the importance of comprehensive and unbiased counseling, which includes discussing all options, including abortion, and providing accurate information 1.

Key points to consider:

  • Parity is defined as the number of pregnancies that have reached viability, typically 20 weeks gestation or a fetal weight of 500 grams
  • Pregnancies that reach viability can have physiological effects on a woman's body and may influence future pregnancy outcomes
  • Accurate documentation of obstetric history, including parity, is crucial for assessing obstetric risk factors and providing appropriate care in subsequent pregnancies
  • Healthcare providers should provide comprehensive and unbiased pregnancy options counseling, including discussion of abortion and post-abortion contraceptive options 2, 1.
