“The body mass index has long been criticized as a flawed indicator of health. A replacement has been gaining support: the body roundness index.” Article unfortunately doesn’t give the freaking formula for chrissakes; it’s “364.2 − 365.5 × √(1 − [waist circumference in centimeters / 2π]2 / [0.5 × height in centimeters]2), according to the formula developed by Thomas et al.10”
I was thinking that this was a bit like with age. Someone telling you online that they’re “25 and a half”, yeah I bet you are lol.
But to me 3cm difference especially in this sort of calculations just seems surprisingly big.
In imperial, it’s in one-inch increments, which is typical. Must have been written in inches and translated for the rest of the world.
