Which term describes a woman's previous pregnancies that resulted in a birth after 20 weeks?

The term that specifically describes a woman's previous pregnancies that have resulted in a birth after 20 weeks is "para." This terminology is used in obstetrics to classify women based on their pregnancy history. A woman who has had one or more pregnancies that resulted in a live birth after 20 weeks is considered "para."

The focus on the 20-week mark is significant because it distinguishes viable pregnancies which generally have a better chance of survival outside the womb, from those that may not be considered full-term. This classification helps healthcare providers assess a woman's reproductive history and any potential risks associated with future pregnancies.

Other terms relate to pregnancy but describe different scenarios. For example, "gravida" refers to the total number of pregnancies a woman has had, regardless of the outcome, and does not specify whether they resulted in a live birth. "Multipara" indicates a woman who has given birth multiple times to viable offspring, while "primipara" describes a woman who has given birth for the first time. Understanding these distinctions is essential for accurate medical communication and care.
