[Hypertension after gestational hyperglycemia].

OBJECTIVE: To compare hypertension frequency in women, 3 to 12 years after the index-pregnancy, when they were classified into 4 groups: NGT: normal glucose tolerance; GHG: gestational hyperglycemia; GDM: gestacional diabetes mellitus; GDM plus GHG.

METHODS: From 3,113 pregnant women, 535 were participants and selected by a process that was randomized and proportional to the group number. NGT women were different from the others in most of the clinical parameters. All women had their blood pressure evaluated. Statistical analyses were performed by Goodman's and chi-square tests.

RESULTS: Hypertension frequency was higher in GDM plus GHG women than in NGT women (40.9 vs. 23.6%; P<0.05). It was similar in GHG and GDM women and not different from NGT and GDM plus GHG women (28.3 and 31.2%, respectively). To have been in GDM plus GHG group increases the risk of hypertension twice.

CONCLUSION: Women with previous GDM plus GHG have higher risk of hypertension, in addition to that of type 2 diabetes.
