Authors: Dr Kavita Sharma, Dr Vinod Kumar, Dr Shahbaz Khan
Background: In India where prevalence of GDM is 8-17% which is comparatively very high, thus there is need for the screening for glucose intolerance so that we can save both mother as well as child from the adverse future outcomes. With a huge population in the reproductive age in India, a significant segment developing abnormal glucose tolerance is a matter concern.GDM women are thus an ideal group for the primary prevention of diabetes.
Aim: The objective of the study was to compare the efficacy of A Single Glucose Challenge Test with conventional 2hr Oral Glucose Tolerance Test for diagnosing GDM.
Materials and Methods: This is a prospective study for a period of one year from Nov.2010 to Oct.2011performed at Obstetric & Gynaecology deptt. of GMC, Jammu. Out of 460 pregnant women, 334 gave their consent to participate in the study. Out of 334, 200 pregnant women completed the study. Subjects at 16-32 weeks of gestation have been evaluated for presence of GDM by doing single Glucose Challenge Test followed by conventional 2hr Oral Glucose Tolerance Test after 3 days.
Results: The present study very effectively supports that 75gm GCT performed on pregnant women is an easy, economical as well as less cumbersome procedure. Hence, this one step procedure serves as both screening as well as diagnostic procedure in a country with limited resources but requiring universal screening.
