Relationship between Insulin Resistance and Pregnancy Induced Hypertension / 中华妇产科杂志

ABSTRACT

Objective To investigate whether insulin resistance is a cause of pregnancy induced hypertension (PIH). Methods All patients who had abnormal 50g glucose screening test accepted 75g oral glucose tolerance test (OGTT) and insulin sensitive index (ISI) was calculated. These patients were followed up and divided into two groups (PIH group and normal pregnancy group) at third trimester of pregnancy. The difference of ISI between the PIH group and normal pregnancy group was compared. Results Fast blood glucose, fast blood insulin and ISI were (4.2?0.7)mmol/L vs. (3.8?0.7)mmol/L, (107.8?48.8)pmol/L vs. (50.4?40.5)pmol/L, and -3.25?0.27 vs. -2.58?0.66 in PIH group and normal group, respectively ( P 0.05). Conclusions Insulin resistance during second trimester of pregnancy may be one of the causes of pregnancy induced hypertension.
