Infant and Maternal Factors Influencing Breastmilk Sodium Among Primiparous Mothers
Bibliographic record
Abstract
OBJECTIVE: This study identified birth events and infant/maternal factors related to breastmilk sodium (Na+) among primiparous mothers. SUBJECTS AND METHODS: Data were collected in a larger study on perceived insufficient milk among 252 breastfeeding mothers at a Canadian, French-speaking university maternal care center. Birth events and infant and maternal factors were collected at 48 hours, 2 weeks, and 6 weeks after birth and were analyzed with bivariate and regression analysis. RESULTS: Presence of gestational diabetes increases the risk of an elevated breastmilk Na+ level at 48 hours, and increased number of breastfeeds (mean=8.91, SD=3.77) lowers it, indicating lactogenesis II was initiated. CONCLUSIONS: Breastfeeding frequency impacts initiation of lactogenesis II, which in turn influences duration of breastfeeding exclusivity. Therefore feedings should be promoted as soon as possible after birth and as frequently as eight to 12 times a day.

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.
