Abstract

OBJECTIVEThe purpose of this study was to investigate the association of cardiovascular risk factors to impaired glucose tolerance (IGT) and to impaired fasting glucose (IFG) in women with prior gestational diabetes mellitus (GDM).RESEARCH DESIGN AND METHODSWe studied 838 women with prior GDM. Postpartum glucose tolerance status was classified as normal, IFG, IGT, IFG plus IGT, and diabetes according to the World Health Organization criteria. Postpartum BMI, waist circumference, blood pressure, triglyceride, cholesterol, and HDL cholesterol were assessed.RESULTSBMI and blood pressure were significantly higher in women with IFG than in women with normal glucose status. BMI and waist circumference were significantly higher in women with IFG plus IGT than in women with normal glucose status. No differences were observed between women with IGT and normal glucose status. The prevalence of hypertension and obesity was significantly increased in IFG compared with normal glucose status. The prevalence of obesity and abnormal lipids was significantly increased in IFG plus IGT compared with normal glucose status. IGT showed no increased prevalence of cardiovascular risk factors.CONCLUSIONSTraditional cardiovascular risk factors have a stronger association with isolated IFG than with isolated IGT in women with prior GDM.
