Maternal and fetal cord blood lipids in intrauterine growth restriction.

Small for gestational age neonates (SGA) could be subdivided into two groups according to the underlying causes leading to low birth weight. Intrauterine growth restriction (IUGR) is a pathologic condition with diminished growth velocity and fetal compromised well-being, while non-growth restricted SGA neonates are constitutionally (genetically determined) small. Antenatal sonographic measurements are used to differentiate these two subgroups. Maternal metabolic changes contribute to the pathogenesis of IUGR. A disturbed lipid metabolism and cholesterol supply might affect the fetus, with consequences for fetal programming of cardiovascular diseases. We evaluated fetal serum lipids and hypothesized a more atherogenic lipoprotein profile in IUGR fetuses.
