Background: The X syndrome, related to coronary disease in adults could be
possibly programmed priory to delivery, in children with intrauterine growt
h retardation. Aim: To measure serum lipids in newborns with symmetrical or
asymmetrical intrauterine growth retardation. Patients and methods: One hu
ndred thirty five newborns with intrauterine growth retardation and 116 nor
mal term newborns, with 38 to 41 gestational weeks, were studied. Total, HD
L, and LDL cholesterol, triglycerides and apoproteins. A1 and B were measur
ed in imbilical cord blood samples. Results: No differences in total, HDL,
LDL cholesterol, apoproteins A1 and B were observed between the study group
s. Triglycerides were higher in newborns with intrauterine growth retardati
on, compared to normal term newborns (45 +/- 27 and 36 +/- 19 mg/dl respect
ively, p<0,001). Differences in serum triglyceride levels respect to contro
ls were observed in both male and female newborns with asymmetrical growth
retardation. Likewise the differences respect to controls were observed in
newborns with mild or severe but not with moderate growth retardation. Conc
lusions: Newborns with intrauterine growth retardation have higher triglyce
ride levels than normal term newborns.
