Data used to create the growth charts for children and teens aged
2 years to 20 years were nationally representative and obtained from
national survey data sets (Kuczmarski et al., 2000).
for the CDC Growth Charts included:
physical measurements of height (also referred to as stature) and weight from children and teens 2 years to 20 years of age.
The measurement data were obtained from a series of national
health examination surveys conducted by NCHS from 1963 to 1994.
These surveys and data sources included:
National Health Examination Survey (NHES), Cycle II (1963-65; ages 6-11y)
National Health Examination Survey (NHES), Cycle III (1966-70; ages 12-17y)
National Health and Nutrition Examination Survey (NHANES) I (1971-74; ages 2-19 y)
National Health and Nutrition Examination Survey (NHANES) II (1976-80; ages 2-19 y)
National Health and Nutrition Examination Survey (NHANES) III (1988-94; ages 2-19 y for stature, ages 2-5 y for weight and BMI)
In each of the cross-sectional surveys, a national probability sample of the civilian, non-institutionalized population of the United States was examined. Survey-specific sample weights were applied to the national survey sample data to assure representation of the U.S. population according to age, gender, and racial/ethnic composition at the time the surveys were conducted.
