Relation between Maternal and Neonatal Serum Lipid Profile and Their Impact on Birth Weight

Abstract

Objective Maternal malnutrition with disturbed lipid metabolism during pregnancy may affect the fetal lipid profile. We aimed to detect the relation between maternal and neonatal serum lipid profile, as well as to detect the serum lipid profile difference between small for gestational age (SGA) infants and appropriate for gestational age (AGA) infants to disclose the impact of maternal malnutrition on birth weight.

Study Design A cross-sectional study was conducted on 150 pregnant women coming to the labor room. Before delivery, maternal serum levels of high-density lipoprotein (HDL), low density lipoprotein (LDL), triglycerides (TGs), and total cholesterol were assessed, then after delivery, cord blood samples were taken for assessment of the neonatal lipid profile. Birth weights were measured, then the neonates were divided into SGA and AGA groups.

Results Serum levels of LDL, TGs, and total cholesterol in the SGA infants were lower than that in the AGA infants. A positive correlation between maternal and neonatal serum TGs levels was found. Besides, there was a positive correlation between birth weight and maternal serum levels of LDL, TGs, and total cholesterol.

Conclusion Maternal serum lipid profile could be an indicator of the neonatal serum lipid profile and birth weight.

Key Points

• SGA neonates have lower levels of serum lipids compared to AGA neonates.

• There is a positive correlation between maternal and neonatal triglycerides.

• There is a positive correlation between birth weight and maternal serum lipids.
