The National Health and Nutrition Examination Survey (NHANES)--NEW--National Center for Health Statistics (NCHS), Centers for Disease Control and Prevention (CDC).
Section 306 of the Public Health Service (PHS) Act (42 U.S.C. 242k), as amended, authorizes that the Secretary of Health and Human Services (DHHS), acting through NCHS, shall collect statistics on the extent and nature of illness and disability; environmental, social and other health hazards; and determinants of health of the population of the United States.
The National Health and Nutrition Examination Survey (NHANES) has, to date, been authorized as a generic clearance under OMB Number 0920-0237. A change in accounting practices, however, requires a shift to a newly-assigned clearance number for future full cycles of the survey.
The National Health and Nutrition Examination Survey (NHANES) was conducted periodically between 1970 and 1994, and continuously since 1999 by the National Center for Health Statistics, CDC.
Annually, approximately 15,411 respondents participate in some aspect of the full survey. About 10,000 complete the screener for the survey. About 142 complete the household interview only. About 5,269 complete both the household interview and the Mobile Examination Center (MEC) examination. Up to 2,500 additional persons might participate in tests of procedures, special studies, or methodological studies. The average burden for these special study/pretest respondents is 3 hours. Participation in NHANES is completely voluntary and confidential. A three-year approval is requested.
NHANES programs produce descriptive statistics which measure the health and nutrition status of the general population. Through the use of questionnaires, physical examinations, and laboratory tests, NHANES studies the relationship between diet, nutrition and health in a representative sample of the United States. NHANES monitors the prevalence of chronic conditions and risk factors related to health such as arthritis, asthma, osteoporosis, infectious diseases, diabetes, high blood pressure, high cholesterol, obesity, smoking, drug and alcohol use, physical activity, environmental exposures, and diet. NHANES data are used to produce national reference data on height, weight, and nutrient levels in the blood. Results from more recent NHANES can be compared to findings reported from previous surveys to monitor changes in the health of the U.S. population over time. NHANES continues to collect genetic material on a national probability sample for future genetic research aimed at understanding disease susceptibility in the U.S. population. NCHS collects personal identification information. Participant level data items will include basic demographic information, name, address, social security number, Medicare number and participant health information to allow for linkages to other data sources such as the National Death Index and data from the Centers for Medicare and Medicaid Services (CMS).
NHANES data users include the U.S. Congress; numerous Federal agencies such as other branches of the Centers for Disease Control and Prevention, the National Institutes of Health, and the
