Summary
Grand multiparity, defined as seven or more deliveries, is associated with increased obstetric risks. This includes higher rates of diabetes, hypertension, and perinatal deaths for both mother and fetus.
Area of Science:
- Obstetrics and Gynecology
- Maternal-Fetal Medicine
- Reproductive Health
Background:
- Grand multiparity has historically been viewed as an obstetric risk.
- Previous studies have suggested potential complications associated with high parity.
Purpose of the Study:
- To evaluate the association between grand multiparity and medical/obstetric complications.
- To investigate the risks of grand multiparity in a large, nationwide cohort.
Main Methods:
- Analysis of delivery records from a nationwide survey in Israel.
- Inclusion of 22,814 women from 30 obstetric wards (November 1983 - January 1984).
- Comparison of outcomes between grand multiparae (≥7 deliveries) and other women.
Main Results:
- Grand multiparity (n=1,542) was significantly linked to increased incidence of diabetes, hypertension, malpresentations, multiple births, and large-for-gestational-age deliveries.
- Perinatal deaths were also more common in the grand multiparae group.
- The observed associations were partially explained by the interplay of parity and maternal age.
Conclusions:
- Grand multiparity is associated with a higher risk profile for several adverse maternal and fetal outcomes.
- Maternal age is a confounding factor that partially explains the risks associated with grand multiparity.
- These findings underscore the importance of careful obstetric management in women with grand multiparity.
