Neighbourhoods and child adiposity: A critical appraisal of the literature
Bibliographic record
Abstract
This paper critically appraised the published literature to determine the relationship between physical and social environmental features of neighbourhoods with child adiposity. MEDLINE, EMBASE, PsychINFO, and SCOPUS were searched from 1999 to July 2009 using a systematic search strategy. Twenty-seven primary studies were included based on a priori eligibility criteria. Socioeconomic disadvantage was consistently shown to increase child adiposity, while there was some evidence that high social capital protected against increased adiposity. It is unclear at this time if and how other neighbourhood environmental features play a role. Heterogeneity and methodological issues across studies limits our ability to draw overall conclusions.

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.
