Determination of cord blood lipid profile in neonates and its correlation with birth weight and maternal anthropometry

Abstract

Introduction: Serum lipid disorders have their roots in childhood and atherogenic changes are postulated to originate early in life. Cord lipid profile is a useful tool in the earlier detection of babies at a higher risk. Objectives: The objectives of the study were to assess the early onset dyslipidemia by determining cord blood lipid profile in healthy term newborns and to compare the cord blood lipid profile between terms small for gestational age (SGA) and appropriate for gestational age (AGA) newborns. Materials and Methods: This prospective observational study was conducted from October 2013 to October 2014 in the Department of Pediatrics of a Tertiary Care Institution of Central India. All normal term newborns with gestational age between 37 and 42 weeks were included in the study. After thorough examination, their weight, length, and ponderal index (PI) were recorded. Cord blood was collected immediately after the delivery and cord lipid profile was measured. Data were recorded and correlated statistically. Results: Of 114 neonates, 71 were AGA, 40 were SGA, and three were large for gestational age. There were 59 (51.8%) female and 55 (48.2%) male neonates. Birth weight, length, gestational age, head circumference, and PI were significantly higher in AGA neonates than SGA neonates (p<0.001, 0.013, 0.022, 0.02, and <0.001, respectively). Total cholesterol (TC), triglycerides (TGs), low-density cholesterol (LDL), and very low-density cholesterol (VLDL) levels were significantly higher in term SGA than term AGA neonates. Conclusion: Birth weight correlated negatively with LDL, VLDL, TC, and TG. Lipid profile parameters were also higher in babies with maternal body mass index ?25 kg/m2.

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

“…Also, the study by Ramy et al showed that there was a strong negative correlation between birth weight and each of TG and LDL. 25,26 The effect of maternal serum lipid profile on neonatal outcome has been studied before but showed varied results. Ghiasi et al found a positive correlation between maternal and neonatal serum total cholesterol levels.…”

“…This is related to maternal pre-BMI and GWG. 14,15,16) There is insufficient evidence to point out the relationship between maternal weight changes, birth weight and steroid hormone metabolism. Furthermore, the reason behind the altered lipid profile is not well understood.…”

“…have shown similar findings of decreased HDL-C levels in neonates with maternal BMI ≥25 kg/m2. 14,26) Increased LDL-C, VLDL-C, triglycerides, and cholesterol levels were seen in LBW/SGA and LGA babies but there was no significant correlation with HDL-C levels 27,28) A c c e p t e d…”

“…The lipid profile in SGA and LGA/macrosomic babies is deranged compared to appropriate for gestational age (AGA) babies. This is related to maternal pre-BMI and GWG [ 14 - 16 ].…”
