Objective: to determine the relationship between triglycerides/high density lipoprotein cholesterol (TG/HDLc) index and indexes HOMAIR (Homeostasis Model assessment) y QUICKI (Quantitative Insulin Sensitivity Check Index) and fetal anthropometrics in healthy pregnant women. Methods: This cross-sectional study evaluated 91 healthy pregnant women aged 16-41 yr, categorized by gestational age: first trimester (TI, n = 29); second trimester (TII, n = 32); third trimester (TIII, n = 30). Oral glucose tolerance test (75g) was performed. Plasma concentrations of glucose, insulin, triglyceride (TG), total cholesterol (TC) and HDLc were measured. Low density lipoprotein cholesterol (LDLc), no-HDLc, TG/HDLc index, HOMA_IR and QUICKI were calculated. Fetal abdominal circumference (FAC) and estimated fetal body weight (EFBW) were evaluated by abdominal ultrasound; uterine height (UH), blood pressure and birth weight were registered. Results: Mean plasma TG, total cholesterol, LDLc, no-HDLc and TG/HDLc, HOMA_IR and QUICKI indexes were significantly higher in TII and TIII compared to TI. In all women analysis, both TG/HDLc and no-HDLc showed a significant correlation with pregestational body mass index (BMI) (r = 0.30, p<0,01; r = 0,26, p<0,05 respectively), FAC (r= 0,38, p<0,05; r = 0,50,, p<0,01 respectively), EFBW (r = 0,39, p<0,01; r = 0,50, p<0,05 respectively) and UH (r= 0,485, p<0,001). Conclusions: our results confirm dislipidemia in pregnancy; the increased values of TG/HDLc and no-HDLc, are related with pre-gestational BMI and fetal anthropometrics.

Keywords : pregnancy; triglyceride/HDLc index; no-HDLc; fetal weight.
