The accuracy of parental reporting of preschoolers' dietary intake using an online self-administered 24-hour recall
Bibliographic record
Abstract
The purpose of the current study was to assess the criterion validity of ASA24-Canada (an online automated self-administered 24-hour dietary recall) for capturing dietary intake among children aged 2 to 5 years (n=40) using parental proxy reporting. The study was conducted in a daycare setting, where parent-reported intake was compared to true intake for three meals. On average across all eating occasions, 79% of the foods consumed by the children were reported by the parents as exact or close matches. Although parents could accurately identify the food/beverage items their children consumed, they significantly overestimated total energy, most nutrients and portion size intakes. The findings of this research suggest the parent-reported ASA24 can allow for the collection of reliable sources of information about food/beverage items children consume; however, further research and improved portion size estimate techniques are needed to ensure that comprehensive intake data is provided.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
