Reported energy intake by weight status, day and Estimated Energy Requirement among adults: NHANES 2003-2008. Federation of American Societies for Experimental Biology Conference. 25:lb251. Interpretive Summary: Technical Abstract: Objective: To describe energy intake reporting by gender, weight status, and interview sequence and to compare reported intakes to the Estimated Energy Requirement at different levels of physical activity. Methods: Energy intake was self-reported by 24-hour recall on two occasions (day 1 and day 2), approximately 10 days apart. Weight status was calculated from measured height and weight. EER was calculated for each individual based on 4 physical activity scenarios, and differences in intake – EER and % of EER were calculated using a sedentary activity level. Means and differences were derived using SAS PROC SURVEY. Results: On average, reported day 1 energy intake was 200-300 kcal higher than day 2 among men, regardless of weight status. Women reported similar intakes on the two days, except for underweight women who also reported higher intakes on day 2. Comparing intake to EER calculated using a default physical activity level of “sedentary”, all individuals over reported energy intake; however, the proportion varied greatly by weight status, with >70% and 60% of obese and overweight, respectively, underreporting vs. 35% of men and 53% of women at a healthy weight status. |
