Brief Summary

Women of reproductive age are at an increased risk of anemia and micronutrient deficiencies. Evidence supports the role of periconceptional nutrition in the development of neural tube defects and other pregnancy complications. Vitamin B12 deficiency is a risk factor for neural tube defects and may modify folate biomarkers that predict neural tube defect risk at the population level. There is an interest in mandatory fortification with vitamin B12 and folic acid for anemia and birth defect prevention. However, there are limited population-representative data needed to inform policy and guidelines. This randomized trial will be conducted to evaluate the efficacy of quadruple-fortified salt (QFS; iron, iodine, folic acid, vitamin B12) in 1,000 women and their households in Southern India.

You may qualify if:

  • Women between 18 and 49 years of age
  • Healthy

  • Stage 2 hypertension (SBP≥140 mm Hg or DBP≥90 mm Hg)
  • Glycated hemoglobin (HbA1c) ≥6.5%
  • Other serious pre-existing medical conditions (e.g., defined as the need for regular medication use), active infections, or acute illnesses
  • Previous pregnancy affected by a neural tube defect (i.e., who have had a fetus diagnosed as affected by a neural tube defect or have given birth to a baby with a neural tube defect) (will be referred to OB/GYN for standard of care, including folic acid supplementation, and excluded)
  • Planning to become pregnant (or planning to have a child) in the next 12 months (will be referred to OB/GYN for standard of care, including folic acid supplementation, and be excluded)
  • Daily micronutrient supplements (i.e., tablets, capsules, dispersible tablets; ≥4 times in the past week)
  • Intramuscular or intravenous interventions containing medications or micronutrients (e.g., iron, vitamin B12, folic acid) in the past 3 months

All salt formulations will be similar in taste, appearance, and texture. Salt will be packaged in bags labeled with color codes known only to the salt manufacturers and a statistician unaffiliated with the study. A statistician unaffiliated with this study will generate a random number sequence for intervention allocation. Blinding will be maintained until initial data analysis is completed.
