A Pilot, Community-Based Interventional Study in a Local Convenience Store to Improve Dietary Outcomes in Children
Bibliographic record
Abstract
Introduction: One contributor to the epidemic of obesity is an unhealthful food environment. This study was designed to assess the feasibility of a community-level intervention in a convenience store on improving the food environment. Methods: This community-based interventional study took place in an urban, low-income, ethnic-minority neighborhood. Children who reported visiting either the intervention store or another neighborhood control store were enrolled. The healthfulness of store offerings was measured, and a diet survey was completed by subjects from both intervention and control stores. Results: At the nine-month follow-up, the intervention store promoted and advertised more healthful items than the community-control store. There was a trend toward increased fruit and vegetable consumption and lower sugar-sweetened soda consumption among the intervention store subjects but not in the control subjects. Conclusions: Improving the food environment is feasible via a community-based intervention utilizing the influence of a community health center.

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.
