Lipid profiles were estimated in two groups of normal healthy women comprising 39 non-pregnant women and 67 pregnant women at 28 and 32 weeks gestation and 6 weeks after delivery. Triglycerides, total, HDL and LDL cholesterols were high during pregnancy. Except for LDL cholesterols which remained constant, all the above decreased at 6/52 postnatally, but levels were still above those of normal non-pregnant women. Compared to the later, the atherogenic index, LDL/HDL cholesterol ratio was unchanged during pregnancy but significantly increased at 6/52 postnatally. These results may suggest that while total lipid levels increase during pregnancy, this is balanced by an even distribution of the lipoprotein fractions. After delivery, though lipid levels had decreased, the decrease in HDL cholesterol and increase in LDL cholesterol caused unfavourable changes in lipid-lipoprotein ratios. These changes may be due to the change in metabolism of the pregnant women as well as diet during and after pregnancy.
