Perinatal plasma lipid concentrations.

The effect of the maternal environment on umbilical cord plasma lipid concentrations was studied in a group of mothers and babies. Changes in neonatal plasma concentrations during the first week of life were followed in a small group of infants. The lipoprotein distribution of the cholesterol and triglyceride content of umbilical cord plasma was similar to that seen in maternal plasma at delivery. Neonatal plasma cholesterol was significantly correlated with the cholesterol content of maternal low density lipoprotein. Neonatal plasma triglyceride concentration was related to maternal parity, duration of labour and the existence of maternal hypertension and to the occurrence of foetal distress and dysmaturity.
