National Health and Nutrition Examination Survey

New Content and Proposal Guidelines

February 12, 2024


The Division of Health and Nutrition Examination Surveys has selected final questionnaire, examination, and laboratory content for the 2025-2026 NHANES cycle. We are diligently working to finalize all remaining aspects of the survey. Data collection is expected to begin in early 2025.

While we are not currently accepting formal proposals for new content, if you are considering an idea for a future component, please feel free reach out to us for advice or technical support. The formal proposal submission deadlines and process guidelines for the 2027-2028 NHANES cycle will be announced through the NHANES listserv.

We appreciate your continuous support and look forward to future collaboration. Please feel free to email us at for any questions or comments.
