National Health and Nutrition Examination Survey

The National Health and Nutrition Examination Survey (NHANES) is a survey research program conducted by the National Center for Health Statistics (NCHS) to assess the health and nutritional status of adults and children in the United States, and to track changes over time. The survey combines interviews and physical examinations. The NHANES interview includes demographic, socioeconomic, dietary, and health-related questions. The examination component consists of medical, dental, and physiological measurements, as well as laboratory tests administered by medical personnel.

The first NHANES was conducted in 1971. Findings from the survey are used to determine the prevalence of major diseases and risk factors for diseases. Information is used to assess nutritional status and its association with health promotion and disease prevention. NHANES findings are also the basis for national standards for such measurements as height, weight, and blood pressure. Data from this survey are used in epidemiological studies and health sciences research, which help develop sound public health policy, direct and design health programs and services, and expand the health knowledge.

Famous quotes containing the words national, health, nutrition, examination and/or survey:

    All men are lonely. But sometimes it seems to me that we Americans are the loneliest of all. Our hunger for foreign places and new ways has been with us almost like a national disease. Our literature is stamped with a quality of longing and unrest, and our writers have been great wanderers.
    Carson McCullers (1917–1967)

    At last I feel the equal of my parents. Knowing you are going to have a child is like extending yourself in the world, setting up a tent and saying “Here I am, I am important.” Now that I’m going to have a child it’s like the balance is even. My hand is as rich as theirs, maybe for the first time. I am no longer just a child.
    —Anonymous Father. Ourselves and Our Children, by Boston Women’s Health Book Collective, ch. 5 (1978)

    Men have their own questions, and they differ from those of mothers. New mothers are more interested in nutrition and vulnerability to illness while fathers tend to ask about when they can take their babies out of the house or how much sleep babies really need.
    Kyle D. Pruett (20th century)

    A clergyman, again, can hardly ever allow himself to look facts fairly in the face. It is his profession to support one side; it is impossible, therefore, for him to make an unbiased examination of the other.
    Samuel Butler (1835–1902)

    By contrast with history, evolution is an unconscious process. Another, and perhaps a better way of putting it would be to say that evolution is a natural process, history a human one.... Insofar as we treat man as a part of nature—for instance in a biological survey of evolution—we are precisely not treating him as a historical being. As a historically developing being, he is set over against nature, both as a knower and as a doer.
    Owen Barfield (b. 1898)
