Effect of grand multiparity on maternal, obstetric, fetal and neonatal results.

Objective: The aim of the study was to compare the incidence of antenatal and intrapartum complications and perinatal outcomes between grand multiparous women of the same age and socioeconomic status and nulliparous and multiparous women.

Patients And Methods: A prospective case-control study was conducted at the Tertiary Center Gynecology and Obstetrics Clinic of the Eastern Anatolia Region between January 1, 2021, and January 1, 2023. It was compared with 149 grand multiparous, 724 multipara, and 258 nulliparous singleton pregnancies. The data were entered separately by two people and then compared. The delivery period, gestation period, maternal obstetric, and fetal and neonatal outcomes of the groups were compared.

Results: The frequency of postpartum hemorrhage, antepartum and postpartum anemia was significantly higher in grand multiparity patients than in other groups. Gestational hypertension, Gestational DM and Abortus imminent, and the frequency of preterm birth increases with parity. The frequency of hyperemesis gravidarum and preeclampsia was significantly higher in nulliparous pregnant women than in others. There was no difference between the groups in terms of premature rupture of membranes and post-term pregnancy. Among the neonatal outcomes, only the frequency of low birth weight was significantly higher in grand multiparous patients.

Conclusions: The frequency of postpartum anemia, postpartum bleeding, gestational hypertension, gestational diabetes, and preterm pregnancy is higher in grand multiparity patients than in multiparous and nulliparous patients. Due to the increased risks with grand multiparity, pregnancy follow-up, and follow-up should be done within the risk factors of these patients in regions where grand multiparity is intense, and family planning practices should be increased.
