However, the interpretation is different. After calculating the BMI, the value is plotted on a [CDC growth chart](https://www.cdc.gov/growthcharts/clinical_charts.htm) specific to the child's age and sex. These charts provide percentiles that categorize BMI as follows:
- Underweight: Less than the 5th percentile - Healthy weight: 5th to less than the 85th percentile - Overweight: 85th to less than the 95th percentile - Obesity: Equal to or greater than the 95th percentile
