Maternal serum lipid levels during late pregnancy and neonatal body size.

Abstract

The aim of this study was to determine the predictive value of maternal serum lipid levels during late pregnancy for neonatal body size. This study was conducted from January 1, 2011 to July 31, 2012 at a Maternal and Child Health Hospital. Fasting blood glucose, serum triglyceride, total cholesterol, HDL and LDL were estimated in maternal collected before delivery. Detailed anthropometry of the neonates was performed. Women who delivered a large for gestational age baby were older, taller, had a higher pre-pregnancy weight, higher pre-pregnancy BMI, and higher weight gain during pregnancy than women who delivered an appropriate for gestational age infant. After adjusting for maternal age, pre-pregnancy BMI, weight gain during pregnancy, parity, neonatal sex and gestational age at delivery, we found that only maternal HDL level was inverse associated with birth weight, length and head circumference (p<0.05). On logistic regression analysis, the significant metabolic predictors of large for gestational age was HDL (OR 0.57, 95%CI: 0.38-0.84, per 1 mmol/L increase) after adjusting for the confounders. Maternal serum HDL level determined in maternal blood taken close to delivery was independently associated with neonatal size and was the independent predictor for large for gestational age.
