closeABSI calculator
Posted by Sada75 on 14 Aug 2012 at 20:19 GMT
I used the calculator at www.ce.ccny...html. Do I understand this correctly that an ABSI score <1 means low risk and above is high risk? If so using the English calculations, a score of .08 relative risk for ABSI was given for a 65 yo woman, 60", 179#, WC 41". This does not seem correct. The same value was given for a 55 yo woman, 62", 103#, 27". Thank you for explaining.

For both sets of values you give, 0.08 is the ABSI. The z-score is < 0 if the ABSI is less than the population average, as is the case here. The estimated "relative risk from ABSI" is 0.8, or lower than average (< 1).

I too found it slightly counterintuitive, having lost 10Kg of abdominal fat (through dieting not through illness) the calculator gives me a higher risk (?) than before. I would even be on a lower risk (?) if I became grossly obese (?) than with my current body shape.
man 51y, 65Kg, 187cm, 78cm WC, (rr 2.2) versus
obese values: 120Kg, 112cm WC (rr 0.8)
or 2 years ago: 75Kg, 85cm WC (rr1.3)
Could it be that at the extremes of BMI people with chronic disease are mixed in with healthy subjects which skews the risk of dying?

In the NHANES cohort that we looked at, people with much lower BMI than average (as in your case) were at higher risk. There is evidence that people who have lost weight through dieting are at lower risk than people who lost weight in general [e.g. http://dx.doi.org/10.2337... ], but in the current study we didn't differentiate by diet or exercise habits.
