OBJECTIVE: Pregnant women with impaired insulin sensitivity are at risk for developing pregnancy-induced hypertensive disorders (PIHD). We analyzed glucose and insulin circulating levels throughout a 2-h oral 75 g glucose tolerance test in pregnant women, and related the 2-h insulinemias to PIHD prevalence.
METHODS: Pregnant women (gestational week 24-28) were submitted to a glucose overload, and glucose and insulin plasma concentrations were measured throughout the test. These peripheral metabolite levels, the homeostasis model assessment (HOMA) values and the glucose to insulin ratio (G:Ir) were analyzed. Anthropometric parameters and pregnancy outcome were recorded.
RESULTS: Women with normal fasting glycemia, insulinemia and HOMA values, G:Ir and 2 h-glycemia but whose 2 h-insulinemia was higher than 215.25 pM were at greater risk for developing late pregnancy hypertension and preeclampsia compared to women of similar characteristics but whose 2 h-insulinemias were lower than 215.25 pM.
CONCLUSION: 2-h insulinemias higher than 215.25 pM after a 75 g glucose overload could be highly indicative of women at increased risk of developing PIHD.
