Community-based communication strategies to promote infant iron nutrition in northern Canada
Bibliographic record
Abstract
OBJECTIVES: To evaluate innovative communication strategies promoting iron nutrition for infants at risk for iron deficiency anemia (IDA) in a northern Aboriginal community. STUDY DESIGN: A prospective process evaluation. METHODS: A social marketing approach was used in the development, implementation and evaluation of the communication strategies. A post-intervention questionnaire was administered to a sample (n = 45) to evaluate reach and exposure of the strategies, and sales of iron-rich infant foods were examined pre- and post-intervention. RESULTS: Multiple communication channels were associated with an increased awareness of IDA and an increased self-reported use of iron-rich infant food. Radio was the most successful channel for reach and exposure of messages. Iron-rich infant food sales increased from pre- to post-intervention (p < 0.05). Breadth of exposure to cooking activity was more limited; however, participants reported increased confidence in preparing homemade baby food. CONCLUSIONS: Communication strategies are a promising strategy for infant IDA prevention where appropriate food is available.

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.
