IOFT in STATA (z-scores for BMI)

[Johan Lerbech Vinther]

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

zanthro is community-contributed. If the IOFT procedures postdate 2013, nothing is public. Suzanna Vidmar is a member here, but in practice I'd email her directly for any news.

Dear Nick,
Many thanks for this - I've emailed Suzanna now, but her auto reply says she is out of office till June 7th 2019. I'm not sure about her email adress - I can only find her @mcri.edu.au-mail
If any other could help me, I would much appreciate it.

Many thanks in advance,

Best wishes,
Johan

Curious if this was resolved. Is there a way to use the IOTF standards to calculate BMI Z scores and overweight/obesity in Stata?
Suzanna Vidmar, do you have advice on this?
