“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”
Maybe to a half inch, but it’s not super popular (except for kids who ALWAYS are proud of that half inch they grew in x period of time). At least, that was the case before I moved to the sanity of metricland.
