📏 Body Roundness Index (BRI)
UseWhen to use: adiposity risk adjunct when waist and height are available.
StrataHigher BRI marks greater roundness / central adiposity cue; cutoffs vary by cohort.
LimitsWhen not to use: as sole cardiometabolic risk tool. · Pitfall: nonstandard waist landmark. · Pair with BMI/labs.

When to use
When to use: adiposity risk adjunct when waist and height are available.
How it works
BRI=364.2−365.5×√(1−((WC/2π)²)/((0.5·height)²)) (meters).
Key points
- Waist + height.
- Adjunct to BMI.
- Next: metabolic workup.

Worked calculation
The values below come from this tool's own example placeholders and are computed server-side with the formula shown on this page, so the arithmetic can be checked quickly. It demonstrates how to substitute values only — it is not clinical advice and not a real case.
| Waist circumference | 90 cm |
|---|---|
| Height | 170 cm |

FAQ
Frequently asked questions
- Does Body Roundness Index (BRI) upload patient data? Where is it calculated?
- Calculation runs locally in the browser; inputs and results are not uploaded. For licensed clinicians only; interpret with history, investigations and local protocols — not a diagnosis or prescription.
- How is Body Roundness Index (BRI) calculated in practice? Can you show a worked example?
- Inputs: Waist circumference 90 cm, Height 170 cm → Result: BRI 3.93（Cue: Mid BRI band — interpret with metabolic risk）
