Hello! I was wondering if anybody has any experience using the cdc-source-code.sas program (available here: https://www.cdc.gov/nccdphp/dnpao/growthcharts/resources/sas.htm) for calculating BMI percentiles and Z-scores? I have a dataset with weights, heights, gender, birth dates and examination dates for patients aged 2-18 years old and am trying to calculate gender-specific BMI-for-height-age percentile and Z-score.
So my main questions are:
1. can the cdc-source-code.sas be used to calculate gender-specific BMI-for-height-age percentiles/Z-scores? If yes, how?
2. Is the gender-specific BMI-for-height-age the same as gender-specific BMI-for-age? My impression is that they're not the same and in that case, I don't think the cdc program can be used (at least not without any modifications) to calculate the gender-specific BMI-for-height-age percentiles/Z-scores but then again, I don't have much experience with this so I could be very wrong.
Thank you for the reference! Unfortunately, it does not provide any information regarding how to obtain sex-specific BMI for-height-age. I know how to calculate gender-specific BMI-for-age but I need gender-specific BMI-for-height-age as this has been proven to be a more accurate measure of adiposity and weight gain for the pediatric population with kidney disease. However, all the online calculators, articles, references, macros I could find all use BMI-for-age, not BMI for-height-age so I don't really know where to find the information I need.
