Summary

Zinc supplementation during pregnancy shows limited benefits, with insufficient evidence for widespread use. Further trials are needed to confirm potential positive effects on preterm delivery rates.

Area of Science:

  • Obstetrics and Gynecology
  • Nutritional Science
  • Perinatal Medicine

Background:

  • Low serum zinc levels have been tentatively linked to labor abnormalities.
  • The association between zinc levels and pregnancy complications requires further investigation.

Purpose of the Study:

  • To evaluate the impact of zinc supplementation during pregnancy on maternal and fetal health outcomes.
  • To determine if zinc intake influences mortality and morbidity in pregnancy.

Main Methods:

  • A systematic review of controlled trials on zinc supplementation in pregnancy was conducted.
  • Data from seven trials were analyzed, with quality assessment and author contact for additional information.

Main Results:

  • Zinc supplementation may potentially reduce the rates of labor induction, cesarean sections, and preterm deliveries.
  • No significant differences were observed in other maternal or fetal outcomes between zinc-supplemented and placebo groups.

Conclusions:

  • Current evidence is insufficient to fully ascertain the effects of zinc supplementation during pregnancy.
  • Additional research is necessary to validate the potential benefits of zinc for preventing preterm birth.
