Dietary data for What We Eat in America, National Health and Nutrition Examination Survey 2007–2008 were analyzed to investigate differences in day 1 and day 2 intakes. USDA's Automated Multiple‐Pass Method was used by trained interviewers to collect each 24hr dietary 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 using the USDA Food Model Booklet containing life‐size drawings of the measuring guides. A sample of men (n = 2250) and women (n = 2433) 20 years of age and older with 2 complete days of dietary data was examined. Two‐day dietary weights were used which adjust for day of the week. A comparison of energy intakes between days for men showed a difference between mean (±SEM) energy intakes of 2,473 ±34.5 kcal for day 1 and 2,352 ±37.7 kcal for day 2 (p<.01). The women reported consuming 1,773 ±25.4 kcal for day 1 and 1,738 ±26.3 kcal for day 2, which were not significantly different When the data were further analyzed by age group (20–39yr, 40–59yr, 60+yr), the mean energy intakes between days showed no differences for either gender (p<.01). Further results will be presented based on differences for the two 24‐hour recalls beyond expected daily variation Funding source: ARS, USDA.
