    NHANES logo, National Health and Nutrition Examination Survey

    Starting in late February, select residents in Tarrant County will have the option to take part in the National Health and Nutrition Examination Survey (NHANES), the most comprehensive survey of the health and nutritional status of the U.S. population. The survey, conducted by the National Center for Health Statistics (NCHS), is part of the U.S. Centers for Disease Control and Prevention (CDC).

    NHANES provides important data on public health problems from a national perspective. "NHANES serves as the nation's 'health check-up,' by going into communities to collect health information throughout the country," according to NCHS Director Jennifer H. Madans. "The survey provides a wealth of important data about many of the major health and nutritional issues effecting the country." 

    The comprehensive data collected by NHANES impacts the every-day lives of the population of all ages, on everything from air quality, to the vaccinations given by doctors, to the low-fat and “light” foods now routinely offered in grocery stores.

    Select county residents will have an invitation-only opportunity to participate in NHANES. Individuals have been selected at random (in a process similar to taking names out of a hat) for NHANES, and include all ages, races, and ethnicities in order to represent the U.S. population as a whole. Respondents first participate in a health interview conducted in the respondent's home followed by a health examination that takes place in the NHANES mobile examination center, set up at the Tarrant Resource Connection.

    While no medical care is provided directly in the mobile examination center, a report on physical findings is given to each participant along with an explanation from survey medical staff. All information collected in the survey is kept confidential and privacy is protected by law.

    For eligible residents who choose to participate in the NHANES:

     

     

    • Information collected about you is confidential, as required by law.
    • You will receive a free and comprehensive health and nutrition evaluation.
    • Your participation can help develop and evolve national health programs and policies.
    • If you are selected, you will help make a difference in our nation's health.
    • Those agreeing to participate will receive compensation for time and travel expenses of up to $125.

    Public health officials, legislators, and physicians use the information gathered in NHANES to develop sound health policies, direct and design health programs and services, and expand the health knowledge for the nation. NHANES findings provide critical health-related information on a number of issues such as obesity, diabetes and cardiovascular disease. In addition, NHANES data are used to produce national references and are used to create standardized growth charts for pediatricians across the country.

    All counties in the United States have a chance to be selected for the NHANES. Tarrant County is one of 15 counties nationally from which residents will be selected to be part of this initiative.
