How it works
The Indian Diabetes Risk Score (IDRS) was developed by the Madras Diabetes Research Foundation from the Chennai Urban Rural Epidemiology Study and is used in Indian screening programmes. It needs no blood test: just age, waist, activity and family history.
A score of 60 or more means high risk, 30–50 moderate and under 30 low. People with high scores should get a fasting blood glucose or HbA1c test. Many Indians with prediabetes have no symptoms at all, which is why screening matters.
The good news: large Indian studies have shown that regular activity and modest weight loss can delay or prevent type 2 diabetes in people at high risk. Read our diabetes prevention guide for practical steps.
Frequently asked questions
Is the IDRS a diagnosis?
No. It estimates risk only. Diabetes is diagnosed with blood tests such as fasting plasma glucose, an oral glucose tolerance test or HbA1c.
How do I measure my waist?
Stand relaxed, breathe out and measure around your abdomen midway between the lowest rib and the top of the hip bone, keeping the tape snug but not tight.
