“…2 , demonstrating that increased fetal serum lipid levels are attributable to increased mobilisation of lipids from fat stores. Our results disagree with the report by Uberos‐Fernández et al 17 , demonstrating the similar maternal and fetal serum‐free fatty acid levels and the significantly lower fetal serum triglyceride levels. Thus, they concluded that transplacental movement of free fatty acid from mother to fetus is important.…”

Objective To investigate whether umbilical cord serum lipid levels differ with mode of delivery.Design Retrospective observation study.Population f i o hundred and ninety mothers aged 29.1 years (SD 4.7) who had vaginal delivery, and 44 mothers aged 30.4 years (SD 4.7) who had elective caesarean section were enrolled.Main outcome measures Maternal and umbilical cord blood were obtained immediately after delivery.Serum lipid levels including total cholesterol, high density lipoprotein cholesterol, saturated fatty acid, mono-unsaturated fatty acid and polyunsaturated fatty acid were measured. Obstetric variables and serum lipid levels were compared between the two groups. In each group the correlations of fetal serum lipid levels with maternal serum lipid levels were investigated.Results There were no significant differences in maternal age, neonatal weight, gestational duration, placental weight and neonatal gender distribution between the two groups. Only the two fetal serum lipid levels (including total cholesterol and non-high density lipoprotein cholesterol) showed a correlation with maternal fetal lipid levels with correlation coefficients > 0.3 in the caesarean section group. However, saturated fatty acid, mono-unsaturated fatty acid and total fatty acid levels in the non-high density lipoprotein low density lipoprotein, very low density lipoprotein, intermediate density lipoprotein and free fatty acid fraction in the umbilical cord serum were significantly higher in the vaginal delivery cases ( P < 0-01).Conclusions Umbilical cord serum levels of saturated and mono-unsaturated fatty acids increase during vaginal delivery.

This study was designed to investigate whether serum lipoprotein (a) is affected by pregnancy and to relate this to changes in other lipids, lipoproteins and apolipoproteins. The study involved twenty-nine healthy Caucasian pregnant women at term and 27 non-pregnant women matched for age who acted as controls. Samples of venous blood were obtained from 29 pregnant women at term (between 37 and 42 weeks) and 22 of these women provided a second sample after 12 weeks post-partum. Twenty-seven non-pregnant women acted as controls. Samples were taken for Lp(a) and also cholesterol, triglyceride, HDL-cholesterol, apolipoprotein (apo) A and B1. No significant difference was found in the serum concentrations of Lp(a). However, the pregnant women had significantly higher serum concentrations of cholesterol, triglyceride, apo A1 and B (P<0.001) than the controls. The ratio of apo A1: apo B was significantly lower than controls (P<0.001). HDL-cholesterol was not altered by pregnancy but was lower (P<0.05) than the controls after a period of 12 weeks post-partum. Despite a hyperlipidaemia in pregnancy the serum concentrations of Lp(a) are not affected suggesting different metabolic control for this lipoprotein.
