Survey description
The National Health Examination Survey, Cycle II (NHES II) was conducted on a nationwide probability sample of 7,417 children 6-11 years of age. Of the 7,417 children selected for the sample, 7,119 (96 percent) were examined. Adjusted sampling weights were computed to inflate the sample so as to reflect the 24 million children in the U.S. population at that time in terms of age, sex, and certain other demographic characteristics.

Data file description
NHES II contains responses to detailed structured questionnaires for medical and developmental histories; responses to school questionnaires; results of medical, dental, and psychological examinations, and vision and hearing tests; and anthropometric measurements.
