Abstract Background Mandatory fortification of staple foods with folic acid is an effective public health strategy to prevent folic acid‐preventable spina bifida and anencephaly (FAP SBA). We estimated the global proportion of FAP SBA prevented through mandatory folic acid fortification of cereal grains (i.e., wheat flour, maize flour, and rice). Methods We used year 2022 data from the Food Fortification Initiative to identify countries ( n = 69) with mandatory fortification of grains that includes folic acid. Sixty‐eight countries were eligible for analysis with complete data. Proportion of FAP SBA prevention was modeled assuming >150 mcg/day of folic acid fortification protects against FAP SBA, reducing post‐fortification prevalence to a lowest achievable level of 0.5 cases per 1000 births. Results Our analysis found that a total of 63,520 cases of FAP SBA were prevented in the year 2022 in 68 countries implementing mandatory folic acid fortification of grains with folic acid. This translated to a 23.7% prevention of all possible FAP SBA prevention globally. An excess of 204,430 cases of FAPSBA still occurred in over 100 countries where mandatory staple food fortification with folic acid is not implemented. Conclusion Our study showed that only a quarter of all FAP SBA cases were averted through mandatory folic acid fortification in the year 2022; many countries are not implementing the policy, resulting in a large proportion of FAP SBA cases that can be prevented. Fortification will help countries with achieving 2030 Sustainable Development Goals on neonatal‐ and under‐five mortality, disability, stillbirths, and elective terminations prevention, from FAP SBA.
