National Health and Nutrition Examination Survey

New Content and Proposal Guidelines

March 16, 2022

Dear Potential Collaborators,

The National Center for Health Statistics (NCHS) invites you to propose content for the National Health and Nutrition Examination Survey (NHANES). This letter describes the procedure for submitting a Content Solicitation Form to propose examination, laboratory, and questionnaire content for NHANES data collection that is scheduled to begin in 2024. There will be a separate process to request renewal of components currently in NHANES.

NHANES will continue to assess the health and nutritional status of adults and children in the United States through interviews, physical examinations, and biospecimen collections. NHANES staff are now in the early stages of planning for NHANES 2024, including exploring alternative sample designs and data collection methods to update and modernize the survey. While details about the sample design and survey operations remain under consideration, we invite you to submit your recommendations for survey content at this time.

We are soliciting physical exam components and other health measures that are best suited for collection in an examination survey. Proposed measures should be validated or represent gold standard methods for data collection for surveillance and research purposes. Content on emerging public health topics is welcome as are assessments using innovative technologies. Requirements for content consideration are:

  • Clear public health importance or significance.
  • Validated methods for data collection, interpretation, and dissemination.
  • Assurance that safety and privacy of survey participants are met;
  • Feasibility for population surveillance and NHANES setting, and
  • Commitment to financial support, including any funding for cognitive, feasibility, or pilot testing.

Proposed content consisting only of questions without complementary exam or lab content is not recommended. Joint proposals within CDC, with other Federal agencies, and with organizations outside the government are encouraged.

If you are interested in partnering with us on the newly redesigned NHANES, please open the fillable Content Solicitation Form and save it as a PDF before filling it out. The content solicitations are due by the following dates:

April 15, 2022: Examination content (alone or with questionnaire and/or lab content)
April 22, 2022: Questionnaire content (alone or with lab content)
June 10, 2022: Laboratory content (alone)

Please email the PDF file to: with the subject line "2024 NHANES New Content".

We plan to review and respond to your proposed content within two months of the receipt deadlines. For content considered feasible for NHANES, a request will be sent out to inquire a detailed proposal. Guidelines for the full proposals will be provided at that time, and proposers will have 6-8 weeks to complete. Depending on the complexity of the proposed content, funding will be required beginning in FY 2023 or FY 2024. NHANES staff can provide cost estimates upon request and are available to discuss any other concerns. If you have any questions about the submission process, please email us at

Our partnerships with new and established collaborators are essential to ensure that NHANES meets its mission to capture an accurate portrait of our nation’s dynamic health. We hope you will decide to be a part of the NHANES renewed vision, and we look forward to hearing from you.
