The Impact of a New Universal Postpartum Program on Breastfeeding Outcomes
Bibliographic record
Abstract
The Ontario Mother and Infant Study II examined changes in postpartum health outcomes, including breastfeeding initiation and discontinuation, for mothers and their infants and compared these results to data collected prior to the initiation of the Universal Hospital Stay and Postpartum Home Visiting Program policy change in 1998. Data were collected using cross-sectional surveys before discharge and at 4 weeks postdischarge. Ninety percent of the women surveyed at 4 weeks postpartum initiated breastfeeding. Of these, 84% were still breastfeeding at 4 weeks postpartum. None of the 3 major program components-extended length of stay, a postpartum phone call from a public health worker, or a postpartum in-home visit-were associated with breastfeeding continuation to 4 weeks. Discontinuation before 4 weeks postdischarge was associated with maternal attitudes toward breastfeeding, formula feeding or supplementation in hospital, infant readmission, and use of walk-in clinics for infant care.

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.
