Child and Adolescent Data in the CDC Growth Chart Reference
The new growth charts for children and adolescents aged 2 to 20 were developed using data from various sources. NHES, Cycle II, included weight and stature data from children and adolescents from 6 through 11 years of age. Data from Cycle III of NHES represented children and adolescents from 12 through 17 years of age. NHANES I, II, and III provided weight and stature data for children from 2 to 20 years of age. However, the NHANES III weight measures were excluded for children 6 years of age and older.
