[Multiparity in Nicaragua].

The relation between birthweight and parity of the mother was examined in Nicaraguan patients from the capital Managua. 7431 births were taken into consideration from 1989-1991. 564 (= 7.6%) of these newborns were born to mothers with more than 5 deliveries. A positive correlation between the increasing number of the parity and the birthweight can be demonstrated in our patients until parity 10, however there are decreases in the birthweight of female newborns between parity 3 to 4 and 5 to 6 and in males between parity 6 to 7 and parity 8 to 9. The average age of a Nicaraguan primipara is 20.7 years and increases by 1.9-2.4 years until parity 5. From parity 6 to parity 15 it increases only by 0.7-1.2 years.
