Serum apolipoproteins A-I and B in male and female full-term newborns of the Toledo study (Spain)

Cord serum apolipoproteins (Ape) A-I and B from 548 healthy, full-term singletons were studied. Females displayed slightly, but significantly, higher Apo A-I levels (p < 0.001) than males, particularly at weeks 38 and 39 (p < 0.05), whereas Apo B was not gender affected but likewise increased (p < 0.05) between weeks 37 and 41. Apo A-I values increased (p < 0.05) with gestational age in males, but with birthweight in females. Results suggest that small gender and age-related metabolic differences exist at birth in term infants.
