Red palm oil as a source of vitamin A for mothers and children: impact of a pilot project in Burkina Faso
Bibliographic record
Abstract
OBJECTIVE: To demonstrate the effectiveness of the commercial introduction of red palm oil (RPO) as a source of vitamin A (VA) for mothers and children in a non-consuming area, as a dietary diversification strategy. DESIGN: A pre-post intervention design (no control area) was used to assess changes in VA intake and status over a 24-month pilot project. SETTING AND SUBJECTS: The pilot project involved RPO promotion in 10 villages and an urban area in east-central Burkina Faso, targeting approximately 10 000 women and children aged <5 years. A random sample of 210 mother-child (12-36-months-old) pairs was selected in seven out of the 11 pilot sites for the evaluation. RESULTS: After 24 months, RPO was reportedly consumed by nearly 45% of mothers and children in the previous week. VA intake increased from 235+/-23 microg retinol activity equivalents (RAE) to 655+/-144 microg RAE in mothers (41 to 120% of safe intake level), and from 164+/-14 microg RAE to 514+/-77 microg RAE in children (36 to 97%). Rates of serum retinol <0.70 micromol l(-1) decreased from 61.8+/-8.0% to 28.2+/-11.0% in mothers, and from 84.5+/-6.4% to 66.9+/-11.2% in children. Those with a lower initial concentration of serum retinol showed a higher serum retinol response adjusted for VA intake. CONCLUSIONS: Commercial distribution of RPO was effective in reducing VA deficiency in the pilot sites. While it is promising as part of a national strategy, additional public health and food-based measures are needed to control VA malnutrition, which remained high in the RPO project area.

How this classification was reachedexpand
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.
