Cord blood vitamin E and lipids in infants born small for gestational age

Vitamin E is associated with the regulation of lipid metabolism. Our previous study revealed an inverse relationship between birth weight and cord blood vitamin E levels, suggesting a potential link between vitamin E and fetal growth. The aim of this study was to determine the association between vitamin E with fetal growth and lipids. In this investigation, a study involving 146 mother-infant pairs was performed. Cord plasma concentrations of vitamin E and lipids were measured. Our findings showed that cord plasma vitamin E levels were elevated in small for gestational age (SGA) infants, and higher vitamin E levels were associated with an increased risk of SGA (OR = 2.239, 95% CI 1.208, 4.742). Additionally, among lipid levels, higher cord plasma triglyceride (TG) levels were associated with increased risks of SGA (OR = 97.020, 95% CI 5.137, 1832.305), whereas after adjusting for confounding factors, the risk became no longer statistically significant. We also found a positive correlation between cord blood vitamin E concentrations and lipid levels.

Conclusion: elevated cord blood vitamin E concentrations may be associated with a higher risk of SGA and are positively correlated with lipid levels, suggesting a potential role for vitamin E in fetal lipid metabolism.
