Hi Everyone,
Can anyone assist me in calculating the BMI Z-score based on the reference population established by the International Obesity Task Force (IOTF)? I have been unable to find a software or package that calculates the BMI Z-score using this specific reference population. Preferably using Stata or R, SPSS .
Any guidance would be greatly appreciated.
You should make the raw data using WHO-NCHS 2005 Antropometri calculator first, than copy to excel than the data can be use to SPSS or STATA. Maybe we can collaborate the data

The formula for calculating the z-score according to the WHO is z-score = (X-m)/SD, in which X is the observed value (height, weight or BMI), m and SD are the mean and standard deviation value of the distribution corresponding the reference population.
