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 What We Eat In America, the dietary interview component of the National Health and Nutrition Examination Survey. The Food Surveys Research Group, having the lead responsibility for the dietary assessment component of NHANES, will assure that 1) the dietary collection method collects accurate data and is valid, 2) the data collected meet stakeholder needs and are released in a timely fashion, 3) the systems for data collection and processing are technologically advanced and efficient, 4) the dietary databases to support data analyses are scientifically sound and current so as to reflect the U.S. food supply at the time of data collection, and 5) the applications developed for collection and processing are made available to the fullest extent possible. Special purpose databases to support specialized research policy needs,including the MyPyramid Equivalents Database used to assess American diets in relation to the Dietary Guidelines for Americans, will be developed and maintained. Temporary Approaches: Approach 1. Continue to review data sets for their completeness and accuracy. Continue to work with NCHS to monitor collection of dietary information, including electronic monitoring for second day collection. Approach 2: Identify knowledgeable individuals with expertise in information technologies to serve as consultants about future needs for evaluating essential and non-essential food components in the foods eaten by Americans. Approach 3. Change hardware and software as appropriate to ensure access to high quality information about the eating behaviors of Americans.
