Description

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.


Parameters:

(1) waist circumference in meters

(2) body mass index in kilograms per squared meter

(3) height in meters

 

ABSI =

= (waist circumference) / ((BMI ^ 0.66667) * ((height)^ 0.5))

 

where:

• 0.66667 is the digital expression for 2/3.

 

This can also be expressed as:

 

ABSI =

= (WC) * ((height)^(5/6)) / ((weight)^(2/3))

 

Interpretation:

• 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.

 

Performance:

• 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.
