Training Module: Using the BMI-for-Age Growth Charts


The 2000 CDC Pediatric Growth Charts include the Body Mass Index (BMI)-for-age growth charts that are recommended for use with all boys and girls aged 2 to 20 years. BMI-for-age is a tool to screen for underweight, overweight, and obesity among children and teens. This module presents the rationale for the use of the BMI-for-age charts, discusses characteristics of the BMI-for-age growth charts, and provides an opportunity for the practical application of calculating BMI, and the plotting and interpreting of BMI-for-age by using case studies.


Upon completion of this module, you will be able to:

  • Describe the advantages of using the BMI-for-age growth charts to screen for obesity, overweight, and underweight among children and teens.

  • Calculate BMI by using the metric and English methods.

  • Demonstrate an understanding of the use of the BMI-for-age growth chart by accurately plotting and interpreting BMI-for-age on the appropriate chart.
