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
Objectives: 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 iodized salt (double-fortified salt, DFS) is a potential strategy to control these problems. To prepare for an intervention trial to evaluate the biological effect of DFS, we assessed women’s usual discretionary salt intake and household (HH) salt utilization rates. Methods: For this cross-sectional study, we used a semi-structured questionnaire to obtain information on socio-demographic characteristics and measured discretionary salt intakes among 100 non-pregnant WRA using observed weighed food records with repeated measurement in 40. We estimated the distribution of usual discretionary salt intake by adjusting for intra-individual variability using the US National Cancer Institute method, and we simulated the potential effects of two levels of folic acid fortification (30 and 90 ppm folic acid) on folic acid intakes. We assessed HH salt utilization by measuring salt disappearance for one week. Results: The women’s mean age was 31 years, 55% had completed any primary education, 75% were married, 56% were housewives, 44% were food insecure and mean HH size was 5. Mean ± SD usual discretionary salt intake was 6.8 ± 3.9 g/day. At the 95th percentile of usual discretionary salt intake, the higher fortification level would provide 918 μg folic acid/day; at the 5th percentile of usual discretionary salt intake, the lower fortification level would provide 124 μg folic acid/day. Estimated household salt utilization was 8.80 ± 6.14 g/person/day. Conclusions: These findings inform plans for a randomized, dose-response intervention trial of DFS and a possible future national program to mandate folic acid fortification of refined, edible salt. The proposed folic acid fortification levels would likely produce a detectable change in red blood cell folate concentration and would not exceed the tolerable upper intake level of 1000 μg/day.

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.
