Diabetes Risk Calculator (FINDRISC)

The Finnish Diabetes Risk Score (FINDRISC) is a short, validated questionnaire that estimates the chance of developing type 2 diabetes within the next 10 years. It was developed by Lindström and Tuomilehto from a 10-year follow-up of a random population sample of Finnish adults aged 35–64 without diabetes, and it needs no blood test: just age, body mass index, waist circumference, physical activity, daily fruit and vegetable intake, blood pressure medication, any history of high blood glucose and family history of diabetes.

This calculator uses the current eight-question version distributed by the Finnish Diabetes Association, which scores 0–26 points and adds family history to the original model. The total maps to five risk bands, from low (about 1 in 100 will develop diabetes within 10 years) to very high (about 1 in 2). Enter height and weight to calculate BMI, in metric or US units.

FINDRISC is a screening tool for adults who do not already have diabetes — it is widely used in Europe and has been validated in many other populations, though calibration varies by ethnicity and country. A moderate or higher score is a prompt to have your blood glucose or HbA1c checked by a healthcare professional; it is not a diagnosis.

Age scores 0 (under 45), 2 (45–54), 3 (55–64) or 4 (over 64). BMI scores 0 below 25, 1 for 25–30 and 3 above 30 kg/m². Waist scores 0, 3 or 4: for men below 94 cm, 94–102 cm and above 102 cm; for women below 80 cm, 80–88 cm and above 88 cm. No daily 30 minutes of physical activity adds 2, not eating vegetables or fruit every day adds 1, ever taking blood pressure medication adds 2 and any history of high blood glucose adds 5. Family history adds 3 for a grandparent, aunt, uncle or first cousin, or 5 for a parent, sibling or child.

The total maps to 10-year risk bands: under 7 low (about 1 in 100), 7–11 slightly elevated (1 in 25), 12–14 moderate (1 in 6), 15–20 high (1 in 3) and over 20 very high (1 in 2).
