Summary

The rate of twin births increased from 1987-2001 due to assisted conception and older maternal age, leading to more preterm births and lower birth weights. Neonatal mortality decreased in the later study period.

Area of Science:

  • Obstetrics and Gynecology
  • Neonatal Medicine
  • Reproductive Medicine

Context:

  • Analysis of 1243 twin births from 609 multiple pregnancies between 1987 and 2001 at Maternidade Bissaya-Barreto.
  • Data grouped into three-year intervals to identify trends in multiple gestations.
  • Investigated the impact of assisted conception techniques and increasing maternal age on twin pregnancies.

Purpose:

  • To analyze trends in multiple gestation rates and associated obstetric and neonatal outcomes.
  • To identify key factors contributing to increased multiple pregnancies.
  • To evaluate changes in neonatal morbidity and mortality over the study period.

Summary:

  • Multiple gestation rates rose, linked to assisted reproductive technologies and advanced maternal age.

  • Common obstetric complications included preterm birth, gestational hypertension, and abnormal fetal growth.
  • Significant neonatal morbidities were hyaline membrane disease, intraventricular hemorrhage, and twin-twin transfusion syndrome.

    • Impact:

    • Identified key drivers of increased twin births, informing reproductive health strategies.
    • Highlighted critical obstetric and neonatal challenges associated with multiple gestations.
    • Demonstrated a reduction in neonatal mortality in the latter part of the study, suggesting improved neonatal care or changing risk factors.
