Brief Summary:
Women with previous gestational diabetes constitute an ideal group for the development, testing, and implementation of clinical strategies for primary diabetes prevention. One-third to one-half of women with a history of GDM will develop type 2 (DM2) within 3-5 years and 70% will develop DM2 if followed \>10 years. Studies have shown that measuring only the fasting glucose level postpartum is not sufficiently sensitive to identify all women who have impaired glucose tolerance (IGT) or DM2. Data presented at the Fifth International Workshop-Conference on GDM indicated that, postpartum, only 34% of the women with IGT or DM2 had impaired fasting glucose and that 44% of those with DM2 had fasting levels below 100 mg/dl (\<5.5 mmol/l). The recommended process to detect permanent diabetes in women who have had GDM and who might become pregnant again is a 75-g 2-h oral glucose tolerance test (OGTT) 6-12 weeks post partum and every year thereafter. Postpartum management of women with GDM is critical because of their markedly increased risk of DM2 and its comorbidities in the future Follow-up studies of women with GDM are necessary to establish the most efficient and most-effective approach to postpartum screening for type 2 diabetes. This study will examine the diagnostic effectiveness of OGTT-derived glucose tolerance, insulin secretion and insulin sensitivity indices compared with indices derived from fasting values of glucose and insulin in subjects with GDM performed post-partum. We will establish whether post-partum fasting and/or glucose-stimulated indices of insulin sensitivity and secretion most accurately estimate the degree of insulin resistance relative to ß-cell function in all race/ethnicity groups of women after delivery of a pregnancy complicated by gestational diabetes and predict their risk for development of diabetes and CVD. .Primary Objective1) We will identify, recruit and test 100 individuals with prior GDM in order to:§ Determine the best way to assess glucose tolerance disorders' prevalence after pregnancy complicated by GDM in southern Louisiana.§ Determine the most effective screening strategy to identify those women with prior GDM who develop or are at high risk for developing DM2 and comorbidities postpartum.A 2 hr, 75-gram OGTT with measurements of insulin and glucose will be performed at their 6-12 week and 1-year post-delivery check-up; this will be compared with the results of their single fasting glucose and insulin value.Secondary Objectives1) We will measure cardiometabolic markers (lipids, blood pressure) in the COPS-GDM study in order to:§ Identify the frequency and value of CVD risk markers in women with glucose abnormalities persisting after pregnancies with GDMGlucometabolic perturbations carry a particularly high risk for metabolic syndrome in women with prior GDM. Woman with prior GDM shown to have higher blood pressure and an altered lipid profile with increased LDL cholesterol and triglyceride levels and decreased HDL cholesterol levels that correlate with cardiovascular disease (CVD) risk factors2) We will measure anthropometric measures (body weight, BMI, abdominal girth) and liver aminotransferase levels (ALT, AST) in order to:§ Determine if there is a higher prevalence of postpartum glucose abnormalities in women with prior GDM predicted by BMI category and/or abdominal adiposity § Determine if elevated abnormal aminotransferase activity is more prominent in prior GDM women and the relationship to subsequent diabetes Former gestational diabetic mothers when compared with women with no history of GDM are found to have higher body mass index (BMI) and visceral adiposity. The distribution of postpartum glucose abnormalities by BMI category was found to be more common with increased BMI.3) We will investigate the impact of breastfeeding in women with a prior GDM on glucose tolerance and CVD risk factors to:§ Determine if lactation has immediate and long-term favorable effects in this patient population postpartum.Breast-feeding has been associated with significantly lower triglyceride level, higher HDL cholesterol, lower total cholesterol/HDL ratio, lower mean fasting glucose, and lower prevalence of any postpartum abnormality of glucose tolerance, including diabetes. Breastfeeding has also been reported to lower the rate of overt diabetes developing later in life in women with a history of gestational diabetes.
