Summary

Maternal zinc levels showed no association with fetal growth restriction in South Indian women. This study found no significant differences in plasma, red blood cell, or white blood cell zinc in mothers of small-for-gestational age babies compared to controls.

Area of Science:

  • Obstetrics and Gynecology
  • Nutritional Science
  • Perinatal Medicine

Background:

  • Maternal zinc deficiency is a potential risk factor for fetal growth retardation.
  • Understanding this association is crucial for improving pregnancy outcomes.

Purpose of the Study:

  • To investigate the association between maternal zinc status and fetal growth retardation in South Indian women.
  • To determine if maternal zinc levels differ between women with small-for-gestational age (SGA) babies and those with appropriate-for-gestational age (AGA) babies.

Main Methods:

  • A prospective study involving 65 mothers of SGA babies and 51 mothers of AGA babies.
  • Assay of zinc levels in maternal plasma, red blood cells, and white blood cells.
  • Evaluation of predisposing factors for intrauterine growth retardation.

Main Results:

  • No significant differences were observed in mean plasma, red blood cell, or white blood cell zinc levels between mothers of SGA and AGA babies.
  • Maternal zinc levels did not correlate with the presence of predisposing factors for intrauterine growth retardation.

Conclusions:

  • Maternal zinc levels are not associated with intrauterine growth retardation in the studied South Indian population.
  • Further research may be needed to explore other factors influencing fetal growth in this demographic.
