Insights
Maternal high-density lipoprotein (HDL) levels near delivery predict neonatal size. Lower HDL is linked to larger babies, suggesting HDL is a key indicator for predicting fetal growth and large for gestational age infants.
Area of Science:
- Obstetrics and Gynecology
- Neonatal Research
- Metabolic Health
Background:
- Maternal metabolic health during pregnancy influences fetal development.
- Understanding predictors of neonatal body size is crucial for perinatal care.
Purpose of the Study:
- To investigate the predictive capacity of maternal serum lipid profiles in late pregnancy for neonatal anthropometry.
- To identify specific lipid parameters associated with neonatal body size.
Main Methods:
- Prospective study conducted at a Maternal and Child Health Hospital (Jan 2011 - Jul 2012).
- Maternal fasting blood glucose, triglyceride, total cholesterol, HDL, and LDL levels were measured pre-delivery.
- Neonatal anthropometry (birth weight, length, head circumference) was meticulously recorded.
Main Results:
- Maternal HDL levels showed a significant inverse association with birth weight, length, and head circumference.
- Logistic regression identified HDL as an independent predictor of large for gestational age neonates (OR 0.57).
- Women delivering larger infants were older, taller, and had higher pre-pregnancy BMI and weight gain.
Conclusions:
- Maternal serum HDL levels measured close to delivery are independently associated with neonatal size.
- HDL is a significant predictor for identifying neonates who are large for gestational age.
Objective:
The aim of this study was to determine the predictive value of maternal serum lipid levels during late pregnancy for neonatal body size.
Methods:
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.
Results:
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.
Conclusions:
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.

Serum lipids are fats and fatty substances in the blood and are crucial for various bodily functions, including energy storage, cellular structure, and hormone production. Serum lipids consist of cholesterol, triglycerides, and phospholipids.
Cholesterol is a soft, fat-like substance found in all body cells. It is crucial for producing hormones, vitamin D, and substances that aid...
