台灣成人食材為主飲食頻率問卷之發展研究

Objectives: Food frequency questionnaires (FFQs) are one of the most important dietary assessment methods in epidemiological studies, collecting subjects’ food frequency information which is able to assess long-term dietary intake. The purpose of this study was to develop the Taiwanese Adult Food Frequency Questionnaire (TAFFQ), a semiquantitative, ingredient-based food frequency questionnaire which use data-driven approach to measure dietary intake of Taiwanese adults. Methods: The food items of TAFFQ were selected from 660 days of 24-hour dietary recalls (24HDRs) (620 24HDRs from mothers and 40 24HDRs from fathers) to identify foods that cumulatively contributed 90% to each following 15 nutrients: energy, protein, fat, carbohydrate, vitamin A, carotene, thiamin, riboflavin, niacin, vitamin C, sodium, potassium, calcium, phosphorus and iron. TAFFQ was developed with nine frequency response section (from never or almost never to 5 or more times per day) to assess frequencies of food consumption over the past year. Results: The average daily intake of energy was 1828kcal, protein was 66g (15% of total energy), fat was 59g (29% of total energy) and carbohydrate was 254g (56% of total energy) of TAFFQ. Conclusion: TAFFQ would be applicable to longitudinal nutrition epidemiological research in the future.
