Welcome to the NHANES Dietary Data Web Tutorial! The National Cancer Institute (NCI), National Center for Health Statistics (NCHS), and U.S. Department of Agriculture (USDA) developed this tutorial to meet the growing needs of NHANES dietary data users.
This tutorial is one of several NHANES Tutorials that have been developed to promote broader and more proficient use of NHANES data.
This tutorial was developed by our collaborators at the National Cancer Institute (NCI/NIH) based on NHANES data available prior to the year 2006. Please note that when new versions of SAS or SUDAAN are released, or updates are made to NHANES webpages and data files, this tutorial will NOT be updated accordingly. Therefore, when you use sample programs from this tutorial, please be advised that you will need to make modifications or changes to the SAS or SUDAAN sample codes in order to run them properly. If you have questions about this tutorial, please contact the National Cancer Institute (NCI) Applied Research Program.
