Diabetes risk check
Framingham diabetes risk calculator
If you have recent blood test results, this calculator estimates your chance of developing type 2 diabetes over the next 8 years. It uses the Framingham Offspring Study score, built from fasting glucose, HDL cholesterol, triglycerides, BMI, blood pressure and whether a parent has diabetes.
Your numbers
Nothing you enter leaves this page. For adults 45 to 64 who do not have diabetes. You need a fasting blood test (glucose, HDL cholesterol and triglycerides in mg/dL).
What you will see
Your points and your approximate chance of developing type 2 diabetes in the next 8 years, from the Framingham table.
Educational only, not medical advice. This is an estimate for groups of people like you, not a diagnosis.
Source
Wilson PW et al., Arch Intern Med 2007 (Framingham Offspring Study, simple clinical model); points, risk table and coefficients from the Framingham Heart Study's page for this paper.
Validated in
Middle-aged adults in the Framingham Offspring Study, Massachusetts, who had an oral glucose tolerance test at the start; 160 developed type 2 diabetes. The authors describe the sample as white. The Framingham Heart Study lists the score for people aged 45 to 64.
Limits
Needs a fasting blood test. Built in one mostly white US community, published in 2007. Does not apply if you already have diabetes or a fasting glucose of 126 mg/dL or more. The percentages are approximate.
What the score predicts
The study estimated the risk of new type 2 diabetes over about 7 years in middle-aged adults who had an oral glucose tolerance test at the start (Wilson 2007). The Framingham Heart Study page for the paper labels the percentages as an 8-year risk, from an average follow-up of 7 years (Framingham Heart Study). The authors built it as a simple way to estimate who is likely to develop type 2 diabetes (Wilson 2007).
How it differs from the other diabetes tools
The type 2 diabetes risk test and the FINDRISC calculator use only questions you can answer at home. This score needs a fasting blood test, because fasting glucose, HDL cholesterol and triglycerides are part of it (Wilson 2007). In the study, a model with only age, sex, parental diabetes and BMI separated people who got diabetes from those who did not with an area under the curve of 0.72; adding blood pressure, HDL, triglycerides and fasting glucose raised it to 0.85 (Wilson 2007). More complex models with a 2-hour glucose test, fasting insulin, C-reactive protein or insulin resistance indexes did no better (Wilson 2007).
The points
| Risk factor | Points |
|---|---|
| Fasting glucose 100 to 126 mg/dL (as printed) | 10 |
| BMI 25.0 to 29.9 | 2 |
| BMI 30 or more | 5 |
| HDL cholesterol under 40 mg/dL in men or under 50 mg/dL in women | 5 |
| Parent with diabetes | 3 |
| Triglycerides 150 mg/dL or more | 3 |
| Blood pressure above 130/85 mm Hg, or on treatment | 2 |
Points come from the Framingham Heart Study page (Framingham Heart Study). Age and sex are in the full equation but not in the points; their odds ratios are close to 1 (Framingham Heart Study). The page prints BMI 30 and triglycerides 150 as "≥" in the coefficient table and as ">" in the point table (Framingham Heart Study); we count 30 and 150 as included. A fasting glucose of 126 mg/dL or more is in the diabetes range (ADA Standards 2026), so this calculator stops there instead of scoring it.
| Total points | Approximate 8-year risk | Total points | Approximate 8-year risk |
|---|---|---|---|
| 10 or fewer | under 3% | 18 | 13% |
| 11 | 4% | 19 | 15% |
| 12 | 4% | 20 | 18% |
| 13 | 5% | 21 | 21% |
| 14 | 6% | 22 | 25% |
| 15 | 7% | 23 | 29% |
| 16 | 9% | 24 | 33% |
| 17 | 11% | 25 or more | over 35% |
The page calls these percentages approximate (Framingham Heart Study). It also prints the full logistic equation behind them; our tests check that the two broadly agree.
A fasting glucose of 100 mg/dL or more carries 10 points by itself, the most of any factor (Framingham Heart Study). That is the prediabetes range, 100 to 125 mg/dL (ADA Standards 2026).
Limits
- The authors say the score was built in a middle-aged white population sample (Wilson 2007). It may fit other groups less well.
- It needs fasting lab results. A single test can differ from day to day.
- It does not diagnose diabetes or prediabetes. Diagnosis uses lab tests read by a clinician, and normally two abnormal results (ADA Standards 2026).
- The percentages are approximate and grouped; a top score shows only "over 35%".
What to do with the number
Bring the result to your clinician. In the US, the US Preventive Services Task Force recommends screening for prediabetes and type 2 diabetes in adults aged 35 to 70 who have overweight or obesity (USPSTF 2021), whatever any risk score says.
