Objective: Tools to assess dietary intakes in older children (7-13 years) are limited. Currently, available assessment tools tend to be time-consuming, rely on caregiver report/assistance, and require a paper-based format. This pilot study aims to develop a technology-based, self-administered, and validated dietary assessment tool for older children that can be used in both clinical and research settings.
Methods: This study utilizes a convenience sample of 60 boys and girls ages 7-13 years who live in the New York City metropolitan area. Children who are not fluent in English, report eating primarily ethnic cuisines, or have severe dietary restrictions are not eligible for participation. To date, 20 children (6 boys) have completed the study. The study has 3 components: 1) completion of a self-administered, web-based, pictorial food frequency questionnaire (FFQ); 2) completion of a 3-day (2 weekdays/1 weekend day), paper-based food record; 3) participation in a focus group. The FFQ includes 1,200 food images with up to 6 portion options and is scientifically validated in adults to assess nutrient intakes/food use patterns for the previous 90 days. During an in-person study visit, children complete the FFQ using a tablet device with minimal assistance. Children then complete the food record within 7 days following the visit. Focus groups are scheduled at the mid-point and end of the study to obtain qualitative data.
Results: The median age of children is 10 (range 7-13). Half of the children are non-Hispanic white, 2 are Hispanic, and the remaining are mixed race/other. Average FFQ completion time is 29.5 minutes (standard deviation (SD), 12.6) and the mean reported calories is 1178.7 (SD, 632.2). Nine children had calorie intakes <1,000, which suggests incorrect completion of the FFQ. Average percentages of calories from carbohydrate, fat, and protein are 51.1%, 36.9%, and 15.0%, respectively. Upon study completion, we will compare energy, macro- and micronutrients intakes between the FFQ and 3-day food record.
Conclusion: This pilot study will provide data to develop and validate a self-administered, web-based FFQ in older children. The food record and focus groups will capture missing items and necessary modifications for the FFQ. The focus groups will also identify areas for improvement, including ease of use.
