Understanding Breastfeeding Behavior: Rates and Shifts in Patterns in Québec
Bibliographic record
Abstract
The study objective was to measure breastfeeding rates and patterns in the Montérégie region of Québec. A survey of 632 mothers of 6-month-old infants was performed, of which 80% initiated breastfeeding, and 68% exclusively breastfed at birth. Breastfeeding rates progressively decreased with time: 63%, 56%, 51%, 44%, 39%, and 32% of mothers breastfed at 1, 2, 3, 4, 5, and 6 months, respectively. Among mothers breastfeeding at a given period, 62%, 57%, 48%, 35%, and 10% of women exclusively breastfed since birth for 1, 2, 3, 4, and 5 months, respectively. Exclusive breastfeeding for 6 months among the 200 women still breastfeeding was practically nonexistent. Introduction of nonhuman milk or solids was primarily responsible for the shift in patterns from exclusive to complementary feeding without passing through predominant breastfeeding. These findings confirm the need to prioritize effective hospital-based and community-based interventions to increase breastfeeding duration and exclusivity in the region.

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.
