Project Type: Appropriated

Start Date: Jan 31, 2004
End Date: Jan 30, 2009

Objective:
Conduct yearly, accurate nationwide data collection of food intakes and related behavior of the U.S. population, and analyze and disseminate survey data. Expand usability of the USDA Dietary Intake Data System and its components to the research community. Maintain the USDA Dietary Survey Databases to reflect the U.S. food supply and release periodic versions.

Approach:
The research approach is to maintain and enhance the components of the USDA Dietary Intake Data System to assure that the dietary collection method, the USDA Automated Multiple Pass Method (AMPM), and the supporting systems and databases result in the collection of dietary data that are scientifically sound, accurate, and valid. The USDA AMPM is being used to collect 10,000 dietary recalls yearly in the What We Eat in America Survey, the dietary component of NHANES. The Food Surveys Research Group has lead responsibility for not only the dietary collection, but also the data processing and release. The numerous applications developed as part of the USDA Dietary Intake Data System for data collection and processing will be continuously maintained and updated, and wherever possible, adapted for use by the nutrition research community.
