Dietary data for What We Eat in America, National Health and Nutrition Examination Survey (NHANES) 2003–2004, contains 2 days of 24‐hr dietary recall data per person. USDA's Automated Multiple Pass Method was used by trained interviewers to collect each recall. The first interview was conducted in person in the Mobile Exam Center, with 3‐dimensional measuring guides available to help estimate food amounts. The second interview was by phone 3 to 10 days later on a different day of the week. A Food Model Booklet containing life‐size drawings of the measuring guides replaced the in‐person guides. Nutrient intakes were estimated based on values from USDA Nutrient Database for Standard Reference release 18 as adapted in the Food and Nutrient Database for Dietary Studies 2.0. Two‐day dietary weights were used; breast‐fed infants and individuals with only 1 24‐hr recall were excluded. A comparison of energy intakes between days showed a mean (±SEM) of 2,166 ±17.1 kcal for day 1 and 2,082 ±16.4 kcal for day 2, a difference of less than 4 percent. When comparing intakes individual by individual, 10 percent of individuals had day 1 and day 2 intakes within 100 kcal of each other. Forty‐two percent of individuals had day 2 intakes that were greater than their day 1 intakes by more than 100 kcal, and 48 percent had day 1 intakes greater than day 2 by more than 100 kcal. Differences between energy intakes for the two 24‐hr recalls will be presented.
