Estimate BMI when heigth and weight are differently estimated

[Florian Maissan]

Hello,

I need to estimate BMI based on the simple technique of; BMI=weight/(height*height) but i'm getting wrong (not possible outcomes). Is it possible to redefine the variables weight and height so that good and reliable BMI estimations can be measured? Is this done with egen? I'm a little bit lost!

Attached I included a .doc file where it is shown how the variable weight (gewicht) and height (lengte) are measured and what the BMI estimations look like now.

Thank you very much in advance for the help!

Greetings,
Florian

note that the formula you cite is for metric measurements only - are your measurements in metric?

[William Lisowski]

And following Rich's question, if the measurements are in metric units, is height measured in meters (not centimeters) and weight in kilograms (not grams)?

If for example your height is measured in centimeters, then you can create a new height in meters to use in your BMI formula with something like the following.

generate lengte_m = lengte/100

Or you could just modify your BMI formula.

generate BMI=10000*gewicht/(lengte*lengte)
