Expert Tip

BRI values closer to 1 indicate a more circular cross-section (higher visceral fat), while lower values indicate a more elliptical shape. BRI > 6.9 is associated with increased mortality risk.

Calculation Methodology & Details

๐Ÿ“

Formula

BRI = 364.2 โˆ’ 365.5 ร— โˆš(1 โˆ’ ((WC/(2ฯ€))ยฒ / (0.5ร—H)ยฒ))

WC is waist circumference in meters, H is height in meters. The formula models the body as an ellipse to estimate central adiposity.
