Indian Diabetes Risk Score calculator
The Indian Diabetes Risk Score estimates the likelihood of undiagnosed type 2 diabetes from age, waist circumference, physical activity and family history. Developed by the Madras Diabetes Research Foundation for Indian populations, a score of 60 or more usually warrants a blood glucose test.
Most diabetes risk scores in circulation were developed on European or American populations, and they systematically underestimate risk in Indians. The reason is well established: Indians develop type 2 diabetes at a lower body mass index, at a younger age, and with more visceral fat at any given weight than the populations those scores were built on.
The Indian Diabetes Risk Score was developed by the Madras Diabetes Research Foundation specifically to address that. It uses four inputs, takes under a minute, requires no blood test, and is designed to identify people who should have their glucose checked.
Indian Diabetes Risk Score
Score, out of 100
50
Moderate risk
The Indian Diabetes Risk Score was developed by the Madras Diabetes Research Foundation specifically for Indian populations, which matters because Indians develop type 2 diabetes at a lower body mass index and a younger age than the populations most international scores were built on. A score of 60 or more is the usual threshold for recommending a blood glucose test.
A screening score, not a diagnosis. It estimates the likelihood of undiagnosed diabetes; only a blood test can establish whether you have it. A low score is not a reason to skip testing if you have symptoms.
Learn to run diabetes screening properly01The four inputs and what they score
**Age** contributes up to 30 points: nothing below 35, 20 points from 35 to 49, and 30 points at 50 or over. Age is the single largest contributor, and it is the one nobody can change.
**Waist circumference** contributes up to 20 points, on sex-specific thresholds — 90 and 100 centimetres for men, 80 and 90 for women. These are lower than the equivalent international cut-offs, deliberately, because abdominal fat carries more metabolic consequence in Indians at a given measurement.
**Physical activity** contributes up to 30 points, running from vigorous exercise or strenuous work at zero through to no exercise combined with sedentary work at 30. Note that this is the largest modifiable factor in the score, and that it counts occupational activity as well as deliberate exercise.
**Family history** contributes up to 20 points: 10 for one parent with diabetes, 20 for both.
02Reading the result
Below 30 is low risk, 30 to 59 is moderate risk, and 60 or above is high risk. A score of 60 or more is the usual threshold at which a blood glucose test is recommended, and that is what the score is for — it is a screening instrument that decides who should be tested, not a diagnosis.
Two things follow that people frequently get wrong. **A low score does not rule out diabetes**, and it is not a reason to ignore symptoms — increased thirst, frequent urination, unexplained weight loss, slow-healing wounds or blurred vision all warrant a test regardless of score. And **a high score does not mean you have diabetes**; it means the probability is high enough that finding out is worthwhile.
03What to do about a moderate or high score
First, get tested. A fasting glucose and an HbA1c are inexpensive, widely available, and settle the question that this score can only estimate.
Second, look at the one input you can change. Physical activity carries up to 30 points, and moving from the sedentary category to moderate activity is both the largest available reduction in the score and a genuine reduction in risk rather than a numerical one. Waist circumference is the second, and it responds to the same changes.
Third, if the test shows prediabetes rather than diabetes, take it seriously. Prediabetes is the point at which the trajectory is most reversible, and the dietary approach is set out in the glycaemic index of Indian foods and diabetes-friendly Indian foods.
04Read it alongside your other numbers
Waist circumference does most of the work in this score, and it is worth looking at on its own — the waist-to-hip ratio calculator covers fat distribution, which is the strongest single predictor of metabolic risk in Indian populations and a better one than body mass index.
The BMI calculator uses the Asian-Indian thresholds of 23 and 25 rather than the international 25 and 30, for the same underlying reason this score exists.
05What a practitioner does with this score
Screening at scale is one of the most useful things a nutrition professional can do in India, and the score is designed for exactly that — at a corporate wellness camp, a community health event, a pharmacy counter or the start of a consultation. It costs nothing, takes a minute, and identifies the people who should be tested.
What follows is the actual work: explaining a result without frightening someone, getting them to a test rather than to a diet plan, and — for those who turn out to have diabetes or prediabetes — building an eating pattern around what their household already cooks. That is the subject of the diabetes educator course, and the boundary with medical treatment is drawn in how to become a diabetes educator in India.
A screening score, not a diagnosis. It estimates the likelihood of undiagnosed diabetes; only a blood test can establish whether you have it. A low score is not a reason to ignore symptoms, and any concern belongs with a doctor.

Expand any question to read the answer in full.
What is the Indian Diabetes Risk Score?
A screening tool developed by the Madras Diabetes Research Foundation to estimate the likelihood of undiagnosed type 2 diabetes in Indian adults. It scores age, waist circumference, physical activity and family history out of 100, requires no blood test, and is designed to identify people who should have their glucose checked.
What score means I should get tested for diabetes?
A score of 60 or more is the usual threshold for recommending a blood glucose test. That said, a lower score is not a reason to skip testing if you have symptoms such as increased thirst, frequent urination, unexplained weight loss or slow-healing wounds — those warrant a test regardless of score.
Why do Indians need a different diabetes risk score?
Because Indians develop type 2 diabetes at a lower body mass index, at a younger age, and with more visceral fat at any given weight than the European and American populations most international risk scores were built on. Applying those scores to Indian bodies systematically underestimates risk, which is why the waist thresholds in this one are lower.
Can I lower my diabetes risk score?
Two of the four inputs are modifiable. Physical activity carries up to 30 points and is the largest available reduction — moving from sedentary to moderately active changes both the score and the underlying risk. Waist circumference carries up to 20 and responds to the same changes. Age and family history cannot be changed, which is why the other two matter more.
Does a high score mean I have diabetes?
No. It means the probability of undiagnosed diabetes is high enough that a blood test is worthwhile. The score is a screening instrument, not a diagnosis — only a fasting glucose or HbA1c test can establish whether you have diabetes, and both are inexpensive and widely available.
