| Summary: | 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. |
