*4.3. BMI Assessment*

Body weight was measured to the nearest 0.05–0.1 kg using an electronic scale and height was measured to the nearest 0.1 cm using a built-in stadiometer (calibrated balance scales, RADWAG WPT 100/200 OW, RADWAG, Czech Republic). The BMI Percentile Calculator was used to calculate BMI in children and teens (https://www.cdc.gov/healthyweight/assessing/bmi/childrens\_bmi/about\_ childrens\_bmi.html).

This calculator provides age- and sex-specific BMI. Normal or healthy weight children had BMI within the range of the 5th percentile and the 85th percentile. Children with BMI within the 85th percentile and the 95th percentile were in the overweight category. Children with BMI equal to or greater than the 95th percentile were in the obese category.
