Differences between the Charts
Here are some of the differences you may notice with the
WHO growth charts:
Length-for-age:
 Slightly more infants and children will plot in the
lower length-for-age percentiles.
Weight-for-age:
 Fewer infants and children will be identified with
low weight-for-age, especially between 6 and 23
months of age.
Weight-for-length:
 Slightly lower number of infants and children with
low weight-for-length.
 Fewer infants and children with high weight-for-
length.
This bar graph compares the growth patterns between the CDC and WHO growth charts.

more extreme cutoffs are used to identify nutrition risk.
 Use new cutoffs at the 2

and 98
percentiles on the WHO charts.

percentiles on the CDC growth charts for older
