Subject: Re:BMI as a measure of obesity

I agree that these longevity studies should use
something other than BMI--it isn't _that_ hard to
calcuate. The formula I have is old--and never
really used optimal statistical tecniques(i.e. think a
good statistician could come up with a better
formula).

The approximate body fat percentage (%) can be
calulated according to the following formula.

Body Fat Percentage = (Body Fat Weight x 100) / total
bodyweight
Body Fat Weight = Total bodyweight - Lean Body Mass<
Lean Body Mass = A + B + E - C - D
Find the values of A, B, C, D, and E from the
following:

For Women:
A =  (Total body weight x 0.732) + 8.987<BR>
B = Wrist measurement (at fullest point) / 3.140
C = Waist measurement (at naval) x 0.157
D = Hip measurement (at fullest point) x 0.249
E = Forearm measurement (at fullest point) x 0.434

For Men:
Body Fat Formula For Men
A = (Total body weight x 1.082) + 94.42
C = Waist measurement x 4.15

measure of fatness.
