In a study, I measure BMI of a large sample of adult people.
Among them, there is some who have very low and very high height.
Some math professor even wrote an article with a "better" calculation of BMI, but with a very low impact in science world (didn't find it on pubmed) so it's not really peer-reviewed.
Let's take some examples, assuming "normal BMI" is 21:
- for a 110cm tall adult, ideal weight is 25kg
- for a 130cm tall adult, ideal weight is 36kg
These weights appear really low to me. Note that dwarfism cutoff is 145cm in France.
My question is then the following: How could I choose a cutoff on height to exclude BMI values ?
NB: I didn't find anything on pubmed nor on google scholar, but maybe I missed an important article
