Plasma lipid concentrations in pre-eclamptic and normotensive Peruvian women.
OBJECTIVE
Dyslipidemia is thought to be of etiological importance in pre-eclampsia. We studied the relationship between maternal plasma lipid concentrations and risk of pre-eclampsia.


METHODS
A total of 125 pre-eclampsia cases and 179 normotensive control subjects were included in this case-control study conducted in Lima, Peru, between August 1997 and January 1998. Postdiagnosis, antepartum plasma lipid profiles were determined by standard enzymatic methods. Logistic regression procedures were used to calculate odds ratios (OR) adjusted for potential confounders.


RESULTS
Mean plasma total cholesterol and triglyceride concentrations were, on average, 6% and 21% higher in pre-eclamptics than controls, respectively. High-density lipoprotein (HDL) cholesterol concentrations were, on average, 9% lower in cases than controls. After adjusting for maternal age, prepregnancy body mass index, education, parity and other potential confounders, the risk of pre-eclampsia increased with successively higher quartiles of plasma triglyceride (adjusted OR: 1.00, 1.62, 2.21, 5.00, with the lowest quartile as referent; P-value for trend < 0.001). The association between pre-eclampsia risk and plasma total cholesterol was much less pronounced. In general, there was an inverse association between pre-eclampsia risk and HDL cholesterol concentration (adjusted OR: 1.00, 0.41, 0.50, 0.38, with the first quartile as the referent group; P-value for trend = 0.02).


CONCLUSIONS
These findings suggest that high triglyceride and low HDL cholesterol concentrations are important risk factors for pre-eclampsia among Peruvian women.
