The Effect of Breastfeeding Education on Adolescent Beliefs and Attitudes: A Randomized School Intervention in the Canadian Ojibwa Community of Sagkeeng
Bibliographic record
Abstract
Sagkeeng First Nation's adolescent breastfeeding educational session was evaluated using a randomized pretest-posttest control group design. The intervention group received the session first; the control group received the session following the posttest. A retention test to measure overall retained learning was given to all students 10 days later. Breastfeeding beliefs increased (mean +/- SD = 41.9 to 47.0, P = .0047) from pretest to posttest for intervention subjects but not for controls. There were no changes in bottle-feeding beliefs or breastfeeding attitudes. There was an increase in breastfeeding beliefs from pretest to retention test for all students (true treatment effect [TTE] = .85 standard deviation units [SDU], P = .004). Learning was gender specific, with females experiencing increases in breastfeeding beliefs (TTE = 1.12 SDU, P = .004), decreases in bottle-feeding beliefs (TTE = -.77 SDU, P = .04), and a trend to increased breastfeeding attitudes (TTE = .41 SDU, NS). Males showed small, inconsistent learning effects. Learning occurred in the areas of health, convenience, cost, and decreased embarrassment.

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.
