Nonfasting Diabetes in Pregnancy Study Group of India versus Fasting Oral Glucose Tolerance Test for Gestational Diabetes Mellitus – Our Experience

Introduction: Gestational diabetes mellitus (GDM) has a prevalence of as high as 20% in different countries of the world. The condition is being diagnosed using different screening methods and guidelines issued by various societies across the world. Diabetes in Pregnancy Study Group of India (DIPSI) test has been used in our country and is also part of the guidelines issued by the MOHFW. This comparative study was conducted to compare the DIPSI test with standard fasting 75 g 2-h OGTT (International Association of Diabetes and Pregnancy Study Group [IADPSG]) in the diagnosis of GDM. Materials and Methods: A comparative control trial was done at a tertiary care center involving 1000 women (500 in each group). The pregnant women were screened for GDM twice during the pregnancy at the first visit (<15 weeks pregnancy) to the ANC clinic and if required second screening was done at 24–28 weeks of pregnancy. The data were collected, and the results were analyzed using MS Excel. Results: The overall prevalence of GDM in our study was 21.4%. The prevalence of GDM in the DIPSI group was the same as GDM in women screened with IADPSG criteria. Conclusion: In our study, DIPSI and IADPSG criteria were found to be equally good in the diagnosis of GDM.
