Dear @ShakilAhmed you can calculate the BMI Z-score and Percentile values using the Anthroplus software, another tool of the WHO. To use it you need the following variables: sex, birth date, measuring date, weight and height

Dear Barbara,

Thanks for your concern.

I have already calculated it. At first, I don't know why, but when I installed Anthro Software, it was calculating only the BMI of under 5 years children skipping the older than 5 years children.

After reinstalling, this problem of mine got resolved.

Use Anthro Plus, it covers children up to 18 years

Shakil, greetings, the age group of 10 to 17 years is a different age group than children, they are pubertal and teenagers, the onset of puberty is not the same in all pubertals and therefore weight gain, height and other variables, so the biological age must first be determined through the Tanner stages. Having the biological age, the WHO references of the multicenter study or NCHS 2000 are used, preferably the first.

Thank you for all of your concerns. Can any of you help me to categorize the health status of these teenage children according to their z-score of WHO standard?

I am planning to categorize their BMI into 5 groups.

1. Severe Thin

2. Thin

3. Normal

4. Overweight

5. Obese

So, what should be the range of z scores (which is calculated using WHO Anthro software) for each of the groups according to WHO standard?

You can suggest to me a better way of categorizing their BMI too. I will appreciate your help.
