Background: diabetes in pregnancy causes a resistance state to the insulin and other metabolic alterations that lead to a high risk of maternal and fetal morbidity. Objective: to analyze the insulinoresistence behavior and some parameters of glucide and lipid metabolism in gestation and pregestation diabetic women. Method: an analytic observational study of longitudinal cohort in fifty-four pregestation and gestation diabetic pregnant women was conducted. Values of serumal concentrations of glucose, insulin, triglycerides, cholesterol and resistance index to insulin were determined, according to the mathematical model HOMA-IR (homeostasis model assessment of insulin resistance) among the weeks ten and fourteen of pregnancy. To all patients were repeated the determinations from the week twenty-eight to thirty-three, obtained values were compared by means of a proportion hypothesis test. Results: high values of triglycerides and cholesterol were presented with more frequency in the third trimester of pregnancy. Also in the case of insulin the high values prevailed in the third trimester, but in the case of the glucose there was not significant difference between both moments. The insulin resistance was bigger in the third trimester. Conclusions: along pregnancy serumal lipids, insulinemia and insulin resistance were increased in both types of diabetic pregnant women. Although pregestation diabetic women presented higher values of the different studied parameters, the fact that these alterations are present in gestation diabetic women conditions that also be a group of high obstetric risk.
