OBJECTIVE: To validate the MDRF-Indian Diabetes Risk Score (IDRS) in a south Indian population in coastal Karnataka. METHODS: The study was conducted at Boloor locality in Mangalore on adults aged 20 years or more. The study group comprised 551 participants (68.9% response rate). The OGTT was performed using 75 gms of glucose. The MDRF-IDRS was calculated using age, family history of diabetes, physical activity and waist measurement. ROC curves were constructed to identify the optimum value (> or = 60%) of IDRS for determining diabetes as diagnosed using WHO consulting group criteria. RESULTS: We found that 71 of the study individuals were known diabetic subjects (KD) while 45 subjects were diagnosed to have newly diagnosed diabetes (NDD). An IDRS score of > or =60 had the best sensitivity (62.2%) and specificity of (73.7%) for detecting undiagnosed diabetes in this community. CONCLUSION: Our study confirms and validates the MDRF-IDRS as being a valid simple and reliable screening tool to identify undiagnosed diabetes in the community. The MDRF-IDRS score > or =60 had the highest sensitivity and specificity to identify undiagnosed diabetes.
