The global challenge of childhood obesity and its consequences: what can be done?
Bibliographic record
Abstract
Although there is concern over the changing epidemiology and increasing trends of obesity in childhood and adolescence, which has risen steadily over the past decade,1 including a robust call for action by WHO,2 progress in reducing the burden at a global level has been negligible. Of greater concern is the recognition that the relative increase in overweight and obesity is greater among poorer sections of the population and in rural areas,3 representing nutrition transition that foretells a future increase in the burden of non-communicable diseases in low-income and middle-income countries (LMICs).

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.
