Summary: The NHES consists of information on a range of health topics, collected through interviews and physical exams. The third round of the NHES was conducted on a nationwide probability sample weighted to reflect the U.S. noninstitutionalized youth population at the time of the survey in terms of age, sex, and certain other demographic characteristics. Nearly one-third of the children examined in NHES cycle II were also examined in this data set. It is possible to identify sample persons examined in both surveys to create a composite data set for longitudinal studies. The following NHES files are available through the EDSC: responses to detailed questionnaires for medical and developmental histories (completed by a household adult); responses to school questionnaires; medical, dental, and psychological examinations; vision and hearing tests; anthropometric measurements; and certain x-ray and laboratory tests.
