Ordered 24-Hrs Recalls Associate with Systematic and Order-Specific Differences in Reported Energy and Carbohydrate Intakes by Individuals with Obesity: A methodological Approach in A Cross-Sectional Study
Abstract Background. In depth understanding of dietary patterns of individuals with obesity is needed in practice and research, in order to support dietitians and physicians in the design and implementation of nutritional management. We aimed to analyze the consistency of energy, macro- and micronutrients reported intakes in four non-consecutive 24-hrs dietary recalls using information collected in the NutriGen Study (ClinicalTrials.gov, NCT02837367).Methods. Data included reported food intakes from 388 adults who completed four 24-hrs recalls. Results. Analyses indicated a significant decrease between the first and subsequent evaluations in regard to energy and several nutrients, with a systematic decrease in reporting energy and carbohydrates for the second evaluation. When excluding the second 24-hrs recall from the average, this new evaluation induced significant increases in the averages for reported energy, carbohydrates, and almost all micronutrients, indicating that the second recall is a point of controversy for whether to be included or not in further analyses.Conclusion. This study identified systematic differences in energy and carbohydrate reporting in the second recall, when four ordered 24-hour recalls were administered to adults with obesity. More studies are needed to identify the source of these differences, in order to ascertain whether reporting, training bias, or behavioral changes are responsible for such differences, and whether a time point with systematic differences should be included or not in further analyses.
