Dietary Screener in the NHANES 2009-10
The National Health and Nutrition Examination Survey (NHANES) is the only nationally
representative survey in the US that administers 24-hour dietary recalls (24HR). While
the 24HR is considered the most accurate self-report method available for population
studies, it currently is very expensive and time-consuming, precluding its use in many
research settings. The goal of this project is to develop and make publicly available a
short dietary instrument calibrated to the 24HR that can be used in resource-constrained
settings.
This project will add an additional dietary instrument to the NHANES in its 2009-10
series. The instrument is composed of 26 questions asking about frequency of intake of
foods and drinks selected to reflect intakes of fruits and vegetables, dairy/calcium,
whole grains/fiber, added sugars, red meat, and processed meat. Specifically, scoring
algorithms to convert frequency responses to intake will be estimated for each dietary
component. The instrument and its scoring algorithms will be publicly available.
Researchers will be able to use the instrument in their own studies and will also be able
to compare their results to national NHANES results.
Collaborators with the National Cancer Institute (NCI) on this project are
the Centers for Disease Control and Prevention
(CDC), the National Heart, Lung and
Blood Institute (NHLBI), NIH's Office of
Behavioral and Social Sciences Research (OBSSR), and NIH's Office of Dietary Supplements (ODS).
