Women's intentions to breastfeed: a population‐based cohort study
Bibliographic record
Abstract
OBJECTIVE: Given that intention to breastfeed is a strong predictor of breastfeeding initiation and duration, the objectives of this study were to estimate the population-based prevalence and the factors associated with the intention to breastfeed. DESIGN: Retrospective population-based cohort study. SETTING: All hospitals in Ontario, Canada (1 April 2009-31 March 2010). POPULATION: Women who gave birth to live, term, singletons/twins. METHODS: Patient, healthcare provider, and hospital factors that may be associated with intention to breastfeed were analysed using univariable and multivariable regression. MAIN OUTCOME MEASURES: Population-based prevalence of intention to breastfeed and its associated factors. RESULTS: The study included 92,364 women, of whom 78,806 (85.3%) intended to breastfeed. The odds of intending to breastfeed were higher amongst older women with no health problems and women who were cared for exclusively by midwives (adjusted OR 3.64, 95% CI 3.13-4.23). Being pregnant with twins (adjusted OR 0.73, 95% CI 0.57-0.94), not attending antenatal classes (adjusted OR 0.58, 95% CI 0.54-0.62), having previous term or preterm births (adjusted OR 0.79, 95% CI 0.78-0.81, and adjusted OR 0.87, 95% CI 0.82-0.93, respectively), and delivering in a level-1 hospital (adjusted OR 0.85, 95% CI 0.77-0.93) were associated with a lower intention to breastfeed. CONCLUSIONS: In this population-based study ~85% of women intended to breastfeed their babies. Key factors that are associated with the intention to breastfeed were identified, which can now be targeted for intervention programmes aimed at increasing the prevalence of breastfeeding and improving overall child and maternal health.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
