Multiple pregnancies increase maternal nutritional needs. Key factors for better birth outcomes include timely maternal weight gain and adequate intake of calcium, magnesium, and zinc.

Area of Science:

  • Obstetrics and Gynecology
  • Maternal-Fetal Medicine
  • Nutritional Science

Background:

  • Multiple pregnancies significantly elevate maternal nutritional demands, depleting reserves.
  • Nutritional status is critical for pregnancy outcomes in twin and triplet gestations.

Purpose of the Study:

  • To investigate the impact of maternal weight gain on birthweight in multiple pregnancies.
  • To identify key nutrients and factors influencing pregnancy outcomes in women with multiple fetuses.

Main Methods:

  • Analysis of maternal weight gain patterns at specific gestational milestones (pre-20 weeks, 20-28 weeks).
  • Evaluation of the influence of parity on gestation length.
  • Identification of essential micronutrients (calcium, magnesium, zinc) for reducing pregnancy complications.

Main Results:

  • Maternal weight gain up to 28 weeks significantly impacts birthweight, especially in underweight women.
  • Higher parity is associated with longer gestation periods (7-10 days).
  • Calcium, magnesium, and zinc show potential in mitigating pregnancy complications.

Conclusions:

  • Optimizing maternal weight gain is crucial for fetal growth in multiple pregnancies.
  • Parity and specific micronutrient intake are important factors for improved pregnancy outcomes.
