Why BMI Percentiles Matter for Girls
Unlike adults, children's BMI is interpreted differently because their bodies are still growing. Percentiles help contextualize BMI relative to other children of the same age and gender:
- Below 5th percentile: Underweight
- 5th to 84th percentile: Healthy weight
- 85th to 94th percentile: Overweight
- 95th percentile or above: Obese
Using these percentiles ensures accurate evaluation of your daughter’s growth patterns.
