Health-related outcomes of new grocery store interventions: a systematic review
Bibliographic record
Abstract
OBJECTIVE: To assess the evidence of the impact of new food store (supermarket/grocery store) interventions on selected health-related outcomes. DESIGN: A systematic review following the Effective Public Health Practice Project guidelines. All quantitative studies were assessed for their methodological quality. Results were synthesized narratively. SETTING: Eight electronic databases - MEDLINE, EMBASE, CINAHL, ProQuest Public Health, Web of Science, Scopus, PsycINFO and Cochrane Library - were searched to identify relevant records. SUBJECTS: Peer-reviewed scholarly journal articles on new grocery store/supermarket interventions with adult study populations, published in the English language after 1995. RESULTS: Eleven records representing seven new grocery store interventions were identified. Six were assessed having 'weak' methodological quality, one as 'moderate' and two as 'strong'. All studies reported fruit and vegetable consumption but results were not consistent, some studies reporting significantly more and others no increase in consumption. BMI and self-rated health did not show significant improvements. Perceptions of food access, neighbourhood satisfaction and psychological health showed significant improvements. CONCLUSIONS: Improved food access through establishment of a full-service food retailer, by itself, does not show strong evidence towards enhancing health-related outcomes over short durations. Presently the field is developing and the complex linking pathways/mechanisms are yet to be elucidated. Further evidence, in the form of high-quality research in different communities with longer follow-up periods, is needed to inform policy decisions.

How this classification was reachedexpand
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.
