AIM: Until recently most dietary survey methods have been developed for non-athletic populations. In this study, we aimed to develop a Food Frequency Questionnaire (FFQ) to assess the regular dietary intake of Brazilian athletes.
METHODS: We interviewed 141 athletes (23.36 ± 7.77 years old) for their dietary intake using 24-hour recalls. After grouping conceptually similar food items into 113 food items, percentage contribution analysis and stepwise regression models were used to highlight foods contributing to at least 90% of the between-person variability of key nutrients.
RESULTS: The developed FFQ contained 59 foods which were important predictors of the variance in nutrient intake. Vitamin C and pyridoxine had the lowest number of selected foods. Conversely, 13 food items were required to explain the between-person variation for energy, carbohydrate and magnesium intake.
CONCLUSIONS: Using a multiple regression analysis we developed a 59-food item questionnaire, which includes culturally specific food items and may represent an important dietary tool to analyse athletic populations. Reproducibility and validity of this FFQ will be verified in future research.
