Poster Topical Area: Nutritional Epidemiology
Location: Hall D
Poster Board Number: 824
Objective: To document the data-based development of a food frequency questionnaire (FFQ) for Korean preschool children.
Methods: Development of the FFQ was based on the data from 2,766 preschool children aged between 1 and 5 years, who had completed 24-hour dietary recalls in the 2009–2013 Korea National Health and Nutrition Examination Survey. For selection of items, we identified the food list based on the results of nutritional contribution and between-person variability for energy and 13 nutrients. Eighty-eight foods with over 80% of total contribution to each nutrient and with over 80% of accumulated square of r for each nutrient were selected. Dish containing any of the 88 foods in the recipe was listed and a total of 903 dishes were extracted. Among the 903 dishes, 438 dishes contributing more than 1% of total consumption for each food from the 88 food list were selected, some of which were combined based on the nutrients content. Finally, 116 dish items were left. Frequency and portion size response choices for items were also determined.
Results: The final 116 dish items consisted of 15 Korean staple dishes, 8 breads, 14 soups and stews, 53 side dishes, 13 dairy products and beverages, and 13 fruits. The percentage of energy, protein, fat, and carbohydrate consumption from the selected 116 items were 89.2%, 88.4%, 88.2%, and 89.4%, respectively. Nine frequency categories for dish items were included. Standard portion size was based on typical portion sizes for each items as reflected in the distribution of dietary data. In addition, when comparing the food portions of child with the standard portion size, subjects would be asked to select one of three response categories of less, similar, and more. If either less or more was selected, a percentage of the standard portion should be recorded.
Conclusions: Dietary intake of Korean preschool children can be assessed by this new data-based FFQ. In addition, the new instrument can be used to identify nutritional needs of target groups for planning nutrition education and strategies to improve diet. Further studies are warranted to evaluate performance of the instrument.
