Dear Everyone,

I using the Zanthro()-function in STATA to BMI z-scores from WHO, CDC etc. I also want to calculate the IOFT z-scores, however I can't find this in the Zanthro()-packkage. Can anyone of you help me?

I've used this command to calculate the z-scores for WHO: egen zbmi_1yFU = zanthro(bmi_1yFU, ba, WHO), xvar(age1yFU_yr) gen(sex) genc(male=1 female=2), which works. So, basically I'm just searching for the command for IOTF.

I hope you can help.

Many thanks in advance,

Best wishes,
Johan
