Objective: To determine the predictors of subsequent development of metabolic syndrome (MS) in women with previous gestational diabetes mellitus (GDM).
Design: Controlled clinical study.
Setting: University hospital.
Patient(s): One hundred sixty-four consecutive women with previous GDM were evaluated after a mean follow-up of 40.54 months from index pregnancy. Sixty-five lean women with negative screening for GDM were included as a control group.
Main outcome measure(s): Subjects were evaluated for diagnosis of MS according to criteria of the National Cholesterol Education Program and the International Diabetes Federation. Tests were performed including a 75-g oral glucose tolerance test (OGTT), fasting insulin, lipids, plasma fibrinogen, blood pressure, and body measurements. The homeostasis model assessment score was calculated.
Result(s): The MS prevalence was higher in women with previous GDM, according to both definitions. Univariate analysis showed that prepregnancy obesity, weight gain during follow-up, and fasting glucose level at the OGTT of the index pregnancy were predictors of developing MS. Multivariate analysis showed that fasting glucose level >100 mg/dL at the OGTT of the index pregnancy was an independent predictor of the MS development.
Conclusion(s): We suggest that early prediction of women with previous GDM who are at high risk for developing MS is possible, and it is vital to prevent MS-related complications.
