How the data is obtained
Graphically, the parity of pregnancy is expressed through the letter P followed by a series of 4 figures which take into account four factors:
- Number of completed births (after 37th week)
- Number of completed preterm deliveries i (between 20th and 37th week)
- Number of lost pregnancies (miscarriages)
- Number of children alive
It should be remembered that in this count the twin birth is considered exactly as a single birth. Therefore, a pregnant woman who in the course of her life has already completed a pregnancy, had a baby in the 30th week and suffered two abortions, is considered pregnant 5, for 1-1-2-2.
Nullipara and pluripara: meaning
- Nullipara is a term that indicates a woman who has never experienced a natural birth,
- Pluripara (para 1, 2, 3 and so on based on the number of previous deliveries) indicates a patient who has already given birth at least once.
