Assessment of Women's Discretionary Salt Intake and Household Salt Utilization in Preparation for a Salt Fortification Trial in Oromia Region, Ethiopia
Bibliographic record
Abstract
There is a high incidence of neural tube defects (NTDs) in Ethiopia and folate insufficiency, a primary risk factor for NTDs, is common among Ethiopian women of reproductive age (WRA). Folic acid fortification of salt has been proposed as a strategy to control these problems. In preparation for an intervention trial to assess the nutritional effects of folic acid-fortified salt, we measured discretionary salt intakes among nonpregnant WRA using observed weighed food records, and we assessed household salt disappearance rates. We estimated the distribution of usual discretionary salt intake by adjusting for intra-individual variability using the National Cancer Institute (NCI) method, and we simulated the potential effects of two levels of folic acid fortification (30 and 90 ppm folic acid) on folic acid intakes. Mean ± SD of usual discretionary salt intake was 6.8 ± 1.9 g/day. At the 95th percentile of usual discretionary salt intake, the higher fortification level would provide 918 µg folic acid/day, which is less than the tolerable upper intake level of 1000 µg/day. At the 5th percentile of usual discretionary salt intake, the lower fortification level would provide 124 µg folic acid/day, which should produce a statistically significant increase in red blood cell folate concentration. Estimated household salt utilization was 8.8 ± 6.1 g/person/day. These findings inform plans for a randomized, dose-response intervention trial of folic acid-fortified salt and a possible future national program to mandate folic acid fortification of refined, edible salt in Ethiopia.

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.
