Abstract

Introduction: Cesarean section is associated with both short-term and long-term maternal and fetal health, particularly in subsequent pregnancies. Therefore, identifying the risks of Cesarean section on subsequent pregnancies is essential. Objectives: To determine the rate of Cesarean section, factors such as placenta previa, premature rupture of amniotic membranes, diabetes mellitus, gestational hypertension; fetal distress, birth weight, and Apgar score of newborns between two groups of primiparous women who delivered vaginally or via Cesarean section for their second delivery at Ca Mau Obstetrics and Peadiatrics Hospital. Subjects and methods: A retrospective cohort study of 2576 second-time mothers at Ca Mau Obstetrics and Peadiatrics Hospital from 2022-2023. Results: The group of mothers with a history of Cesarean section during their second pregnancy had a higher risk of Cesarean section, placenta previa, premature rupture of amniotic membranes, diabetes mellitus, and gestational hypertension compared to the group of others who had a vaginal delivery for their first delivery, with RR values of 5.68 CI 95% [4.60-7.02]; 1.21 CI 95%[1.11-1.31];1.45 CI95%[1.31-1.61]; 1.24 CI95%[1.08-1.43]; 1.39 CI95%[1.26-1.53]; 1.19 CI95% [1.03-1.37], respectively. However, there was no difference in gestational diabetes mellitus between the two groups, p=0.69. Regarding newborns, those born to mothers who had a Cesarean section had a higher risk of fetal distress and low birth weight compared to those born vaginally, with RR values of 1.51 CI 95% [1.38-1.63] and 1.24 CI 95% [1.08-1.42], respectively. Conclusion: Mothers with a history of Cesarean section are at risk for both themselves and their children and are almost always required to have a Cesarean section in subsequent pregnancies.
