Krakauer and Krakauer reported a body shape index (ABSI). This correlates with a patient's risk of mortality. The authors are from the City College of New York and Middletown Medical in New York.
(1) waist circumference in meters
(2) body mass index in kilograms per squared meter
(3) height in meters
= (waist circumference) / ((BMI ^ 0.66667) * ((height)^ 0.5))
• 0.66667 is the digital expression for 2/3.
This can also be expressed as:
= (WC) * ((height)^(5/6)) / ((weight)^(2/3))
• The 50th percentile for ABSI was 0.0809 in Figure 4.
• The relative death rate is increased when the ABSI is 0.09 or above.
• The authors claim that the ABSI predicts mortality hazard independent of the body mass index. Since the ABSI is derived from the BMI it may not be independent.
