Background: Worldwide the burden of Diabetes mellitus (DM) is ever increasing and 46% of the diabetics are undiagnosed. Projections for India reveal that the diabetic population will increase from 65.1 million to 79.4 million diabetics by 2030. With increasing burden, there is a need to use community-based, simple screening tools to identify the undiagnosed. This study uses the Indian Diabetes Risk Score (IDRS) for identification of diabetic risk and diabetic status in a rural population.

Methods: This community-based, cross-sectional study was conducted among 100 subjects between May and July 2013 in a rural population of Kancheepuram district, Tamil Nadu, India. IDRS was used to assess the risk status followed by fasting and 2-hour post-prandial blood glucose measurements to identify the diabetic status.

Results: According to IDRS classification, 59% of the participants were classified under high risk category, 30% had moderate risk and 11% had low risk. Seven participants (7%) were newly diagnosed with diabetes and 19 participants had impaired glucose tolerance. At a score of ≥ 60, IDRS predicted risk of DM with a sensitivity of 85.7% and specificity of 43%.

Conclusion: IDRS is an easy-to-use, economic tool for community-based screening for DM in previously undiagnosed populations.

Key words: Diabetes mellitus, Indian Diabetic Risk Score (IDRS), Screening
