Comparison of 1-Year Food Frequency Questionnaire Data with 3-Day Food Record in Adults

Food frequency questionnaires (FFQs) and 3-day food records (FRs) are widely used methods of dietary analysis and thus need to be accurate. Nutritional values obtained from 1-year FFQ and 3-day FR in 50 participants were compared. No significant differences were observed in energy, carbohydrate, protein, and fat. Differences were observed for dairy intake and 18 micronutrients. Spearman correlation showed significant relationships between 27 nutrients, the highest was cholesterol ( r s = 0.62). Bland-Altman analysis showed a wide level of agreement between the FFQ and FR indicating a need to utilize multiple methods to improve the consistency and accu-racy of dietary analysis.
