Case study questions and activities
1. Plot Phoebe's growth. What growth charts do you use to plot Phoebe's weight and length measurements on?
The WHO weight-for-age and length-for-age charts are used from birth to 2 years of age. After 2 years of age the CDC charts can be used. At this age height rather than length should be measured. CDC BMI charts can also be used from 2 years of age.
