Kahn reported the Lipid Accumulation Product (LAP) based on waist circumference and serum triglyceride concentration. The author is from the National Center for Chronic Disease Prevention and Health Promotion.


(1) gender

(2) waist circumference in cm

(3) serum triglycerides in mmol/L


LAP in a male =

= ((waist circumference) - 65) * (triglyceride concentration)


LAP in a female =

= ((waist circumference) - 58) * (triglyceride concentration)


If the waist circumference for a male is <= 65 cm then 66 is used to avoid a negative number. In theory a female with a waist circumference <= 58 should have 59 used.



• A high LAP is associated with increased cardiovascular risk and hepatic steatosis.
