Abstract
Childhood obesity is increasing at an alarming rate worldwide, especially in developed countries.Between 1979 and 2004, the percentage of overweight and obese children in Canada rose from 15% to 26%. 1 Obesity in children is associated with increased risk of adulthood obesity and multiple health problems including cancer, type 2 diabetes and atherosclerosis. 2 All of these diseases create additional costs for an already overburdened health care system.Multiple explanations for childhood obesity have been proposed, including decreased physical activity, energy-rich diets, socio-economic status, education, genetics, and poor community design.1,2 Many interventions targeting diet, physical activity and environment have been proposed, implemented, and proven mildly successful.3 However, the family and the home are integral factors in childhood obesity that are still being largely overlooked.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
