Two to 20 years: female patients. BMI-for-age percentiles. The BMI of a female patient (Case 1) who transitioned from having normal weight to having severe obesity between the ages of 10 to 14 years was plotted by using the CDC 2000 BMI-for-age-sex growth chart, and the BMI of a female patient (Case 2) with underweight problems was plotted by using the CDC 2000 BMI-for-age-sex growth chart.
