USDA’s National Household Food Acquisition and Purchase Survey: Methodology for Imputing Missing Quantities To Calculate Healthy Eating Index-2010 Scores and Sort Foods Into ERS Food Groups

We use data from the U.S. Dept. of Agriculture’s 2012-13 National Household Food Acquisition and Purchase Survey (FoodAPS) to develop a methodology for imputing missing quantities for item-level data. To check the quality of these imputations, we compare the overall nutritional quality of 7 days of household-level acquisitions reported in the FoodAPS survey to 2 days of individual-level dietary intakes as reported in the 2011-12 National Health and Nutritional Examination Survey (NHANES). The comparison shows that while there are some slight differences in the Healthy Eating Index-2010 (HEI-2010) component densities, both surveys show that Americans acquire too few fruits, vegetables, and whole grains and obtain too much salt and too many refined grains and empty calories. We also describe the method used to classify food items into the ERS food groups developed for FoodAPS.
