Comprehension and use of Nutrition Facts panels among young people in Canada (1025.15)
Bibliographic record
Abstract
Adolescent and young adults are important populations to target for nutrition interventions given their relatively poor diets. Adolescence and young adulthood is also a period of transition, characterized by increasing independence, a growing role in food shopping, and the development of long‐term eating patterns that can track throughout adulthood. Nutrition Facts Labels are the most prominent source of nutrition information for adults in Canada; yet, very little is known about if and how young people understand and use these tools. This research sought to examine if and how young people in Canada engage with and construct meaning from information in Nutrition Facts Labels when choosing and comparing pre‐packaged foods, and test modifications to Nutrition Facts Labels. Study 1 consisted of an online survey with a sample of 2,000 young people ages 16‐24 from across Canada, including a between‐participants experiment to empirically test the efficacy of the current and modified Nutrition Facts Labels on comprehension and use of serving size and percentage daily value information when choosing and comparing foods. Study 2 used qualitative methods with a sample of 26 participants ages 16‐24 to explore the process by which young people engage with, understand, and use serving size and percentage daily value information on the current and modified Nutrition Facts Labels. These data were collected concurrently. The results from the two sub‐studies were triangulated during interpretation to facilitate a more complete understanding of young peoples’ ability to comprehend and use nutrition information on the Nutrition Facts Labels and the potential need for changes to Nutrition Facts Labels. Results will inform regulatory changes to the Nutrition Facts Label in Canada and other jurisdictions, as well as provide evidence to support interventions for improving young people’s understanding and use of Nutrition Facts Labels when choosing and comparing food products.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
