Sanjeev Thakral, SS Haldiya, Harsh Kumar Garg



The study was conducted at Amer locality in Jaipur on adults aged 20 years or more to validate the Indian Diabetes Risk Score (IDRS). The study group comprised 551 participants (68.9% response rate). The OGTT was performed using 75 g of glucose. The IDRS was calculated using age, family history of diabetes, physical activity and waist measurement. ROC curves were constructed to identify the optimum value (> 60%) of IDRS for determining diabetes as diagnosed using WHO consulting group criteria. It was found that 71 of the study individuals were known diabetic subjects, while 45 subjects were diagnosed to have newly diagnosed diabetes. An IDRS score of > 60 had the best sensitivity (62.2%) and specificity of (73.7%) for detecting diabetes in this community. This study confirms and validates the IDRS as being a valid, simple and reliable screening tool to identify undiagnosed diabetes in the community. The IDRS score > 60 had the highest sensitivity and specificity to identify undiagnosed diabetes.
