الملخص EN

Metabolic changes have been correlated with adverse pregnancy outcomes.

The aim of the present study is to determine the TyG and TG/HDL-c indices in a cohort of healthy pregnant (n=142), preeclamptic (n=18), and healthy nonpregnant women (n=56).

Preeclamptic women were selected from the same cohort.

Pregnant women were followed during three periods of pregnancy and postpartum.

The results showed a significant increase in the values of TyG and TG/HDL-c (p<0.01) as pregnancy progresses, without significant differences between healthy and preeclamptic women.

TyG and TG/HDL-c indices are significantly low in nonpregnant and three months’ postpartum women when compared with each gestational period studied.

TyG and TG/HDL-c indices are positively correlated with HOMA-IR in the early and middle pregnancy (p<0.05).

Multiple linear regression using the TyG and TG/HDL-c indices as dependent variables showed that TyG index was significantly associated with HOMA-IR, gestational age, HDL-c, TC, LDL, fasting insulin, and mean BP (p<0.001); meanwhile, TG/HDL-c index was only associated with HOMA-IR (p<0.0242) and gestational age (p<0.001).

In conclusion, the TyG and TG/HDL-c indices could be useful in monitoring insulin resistance during pregnancy.
