Abstract: Objective This study aimed to compare dietary intake estimates using two different methodological approaches: use of new portions obtained with the 24-Hour Diet Recall, which was applied in the current study population, and the application of calibration equations, which were estimated using the same 24h-recalls. Methods Calibration equations were estimated using linear regression. The medians and confidence intervals of energy and nutrient intakes were assessed using all the approaches. The U Mann Whitney te… Show more

“…Another approach taken in this study was the estimation of FFQ2 calibration factors and the correction of data by the reference method, mainly necessary for questionnaires that will be used in studies that assess the diet-disease relationship [27]. The absence of bias in the questionnaire, represented by a calibration factor close to 1, indicates that the mean intake estimated through the questionnaire is similar to the mean estimated using the reference method [28].…”

“…Several instruments are used to assess food intake, which is one of the aspects of eating behavior [5,8,[10][11][12][13][14][15][16][17][18][19]. However, there is no foolproof assessment of the food consumption method [20,21]. The 24-hour recall is the most suitable approach to quantify and assess food and nutrient intake [7,18,22,23].…”
