In our experiment we observed that hemodynamic adaptation pattern correlated with BMI and BSA separately, but stronger so with their quotient (BMI/BSA), which we have called the BMI/BSA-Index.
Has anyone encountered such a term before?
Any opinions on introducing such an index?
Thank you.
Fascinating!! Which BSA equation are you using? I have seen DuBois used frequently but I have also seen other equations for BSA as well. I guess the units of your index would be Kg/m4. I have not seen this used before, however I think that it may be a very interesting quotient to investigate since BMI usage is very limiting with the obese population. I am excited to see what other answers you will receive.
Thank you both for your answers.
We used the Quetelet Index for BMI and the DuBois Formula for BSA. And, indeed, our unit then is kg/m4.
The introduction of the term and the discussion of its meaning/use is the tricky bit, hence why we want to see whether if this has already been defined in a publication. DuBois (BSA) is applicable to estimate body fat in obese and non-obese people, which is not possible with BMI. With this index we take both into account. A correlation with this index also suggests a strong hemodynamic adaptation variance between high BMI + low BSA and low BMI + high BSA, which are interesting combinations to think of in relation to orthostatic stress.
Dear Zeynep. In my opinion for the studyorthostatic stress more interesting ratio thoracic and abdominal circles
