National Health and Nutrition Examination Survey

New Content and Proposal Guidelines

March 30th, 2022


The Division of Health and Nutrition Examination Surveys is pleased to announce that the next NHANES data collection contract has been awarded, and the data collection will begin in 2025. We have thoroughly reviewed and evaluated questionnaire, examination, and laboratory proposals submitted to us for inclusion in the upcoming NHANES. Discussions will begin in the next week with the proposers to assist us in making decisions regarding final survey content.

Concurrently, we are working on finalizing the 2025 sample and operational design to update and modernize the survey. The goal is to increase participation and improve overall response rates to support the production of accurate and timely national estimates of the health and nutritional status of adults and children in the U.S.

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