12. Steps to plot and interpret BMI-for-age

The six steps outlined here to plot and interpret BMI-for-age are similar to those used for a general growth assessment.

	Step 1: Obtain accurate weights and height measurements Step 2: Select the appropriate growth chart (based on the age and gender of the child being weighed and measured) Step 3: Record the data Step 4: Calculate BMI Step 5: Plot measurements Step 6: Interpret the plotted measurements

An instruction sheet on Use and Interpretation of the CDC Growth Charts contains detailed instructions for the above steps.
