Summary
Adequate zinc intake is crucial for pregnant women, as zinc deficiency (ZD) can harm fetal development and parturition. Screening high-risk groups and potential supplementation are recommended to prevent adverse outcomes for mother and child.
Area of Science:
- Maternal and Fetal Nutrition
- Human Teratology
- Reproductive Health
Background:
- Zinc is vital for fetal growth and development, with deficiency impacting both animals and humans.
- Pregnancy is associated with decreased plasma zinc levels, necessitating continuous intake.
- Alcohol intoxication can exacerbate the effects of zinc deficiency in pregnant individuals.
Purpose of the Study:
- To review the role of zinc in pregnant women's nutrition.
- To examine the relationship between zinc and prenatal growth and parturition.
- To highlight the risks of zinc deficiency during pregnancy.
Main Methods:
- Literature review on zinc's role in pregnancy.
- Analysis of studies on zinc deficiency in animal models and humans.
- Examination of data on plasma zinc levels and amniotic fluid zinc content.
Main Results:
- Zinc deficiency (ZD) is teratogenic in animals and humans, affecting fetal development.
- Plasma zinc levels decline during pregnancy, underscoring the need for adequate intake.
- Adverse effects on parturition and potential harm to mother and fetus from mild ZD.
Conclusions:
- Continuous zinc intake is essential for normal embryonic development.
- Amniotic fluid zinc may relate to fetal growth, but its indicator value is debated.
- Screening high-risk groups, establishing dietary intake guidelines, and zinc supplementation are necessary.
