Folic Acid-Fortified Iodized Salt and Serum Folate Levels in Reproductive-Aged Women of Rural India: A Nonrandomized Controlled Trial.

Importance: India has a disproportionately high prevalence of neural tube defects, including spina bifida and anencephaly (SBA), causing a high number of stillbirths, elective pregnancy terminations, and child mortality; India contributes a large proportion of the global burden of SBA. Thirty years after folic acid was shown to be effective in reducing SBA prevalence, only about one-quarter of such births are prevented globally through cereal grain fortification. Objective: To determine the association of folic acid-fortified iodized salt with serum folate concentrations among nonpregnant and nonlactating women of reproductive age. Design, Setting, and Participants: This nonrandomized controlled trial using a preintervention and postintervention design was conducted in 4 rural villages in Southern India from July 1 to November 30, 2022. All households in the villages agreed to participate in the study. Preintervention and postintervention serum folate levels were analyzed among study participants at baseline and after 4 months, respectively. Intervention: Consumption of approximately 300 µg/d of folic acid using double fortified salt (folic acid plus iodine). Median serum folate concentrations were assessed at baseline and 4 months. Main Outcomes and Measures: Change in median serum folate levels between baseline and study end point as the primary outcome of the study. Results: A total of 83 nonpregnant nonlactating women aged 20 to 44 years (mean [SD] age, 30.9 [5.1] years) were eligible for the study and provided serum samples for analysis at baseline and the end point of the intervention. The median serum folate concentration increased from 14.6 (IQR, 11.2-20.6) nmol/L at baseline to 54.4 (IQR, 43.5-54.4) nmol/L at end of study, a 3.7-fold increase from baseline to study end point. Two-tailed Wilcoxon signed rank test showed the median difference in preintervention and postintervention serum folate concentrations to be highly significant (P < .001). The participants found the salt acceptable in color and taste. Conclusions and Relevance: Use of folic acid-fortified iodized salt was associated with increased serum folate concentrations in women of reproductive age. This novel evidence can inform public health policy to accelerate SBA prevention. Trial Registration: ClinicalTrials.gov Identifier: NCT06174883.

Barriers and facilitators to the implementation of mandatory folate fortification as an evidence-based policy to prevent neural tube defects.

BACKGROUND: Neural tube defects continue to be one of the main congenital malformations affecting the development of the nervous system and a significant cause of disability and disease burden to individuals living with these conditions. Mandatory food fortification with folic acid is, by far, one of the most efficacious, safe, and cost-effective interventions to prevent neural tube defects. However, most countries fail to effectively fortify staple foods with folic acid, impacting public health and healthcare systems and generating dismal disparities. AIM: This article discusses the main barriers and facilitators for implementing mandatory food fortification as an evidence-based policy to prevent neural tube defects worldwide. METHODS: A comprehensive review of the scientific literature allowed the identification of the determinant factors acting as barriers or facilitators for the reach, adoption, implementation, and scaling up of mandatory food fortification with folic acid as an evidence-based policy. RESULTS: We identified eight barriers and seven facilitators as determinant factors for food fortification policies. The identified factors were classified as individual, contextual, and external, inspired by the Consolidated Framework for Implementation of Research (CFIR). We discuss mechanisms to overcome obstacles and seize the opportunities to approach this public health intervention safely and effectively. CONCLUSIONS: Several determinant factors acting as barriers or facilitators influence the implementation of mandatory food fortification as an evidence-based policy worldwide. Notoriously, policymakers in many countries may lack knowledge of the benefits of scaling up their policies to prevent folic acid-sensitive neural tube defects, improve the health status of their communities, and promote the protection of many children from these disabling but preventable conditions. Not addressing this problem negatively affects four levels: public health, society, family, and individuals. Science-driven advocacy and partnerships with essential stakeholders can help overcome the barriers and leverage the facilitators for safe and effective food fortification.

Neural tube defects: a review of global prevalence, causes, and primary prevention.

Neural tube defects (NTDs) are common birth defects and contribute to life-long disabilities, high medical care costs, and perinatal and child mortality. This review is a primer on prevalence, causes, and evidence-based prevention strategies for NTDs. The estimated average global prevalence of NTDs is two cases per 1000 births, amounting to approximately 214,000-322,000 affected pregnancies worldwide annually. Prevalence and associated adverse outcomes are disproportionately high in developing countries. NTDs have multiple risk factors including genetic and non-genetic (i.e., maternal nutritional status, pre-pregnancy diabetes, early pregnancy exposure to valproic acid (anti-epileptic medication), and a previous pregnancy affected by a NTD) factors. Maternal folate insufficiency before and during early pregnancy is the most common risk factor and is preventable. Folic acid (vitamin B9) is required for formation of the neural tube early in pregnancy, around 28 days after conception, when most women are unaware of their pregnancies. Current guidelines recommend that all women planning or capable of pregnancy take a daily supplement containing 400-800 µg of folic acid. Mandatory folic acid fortification of staple foods (e.g., wheat flour, maize flour, rice) is safe, economical, and the effective intervention for primary prevention of NTDs. Currently, about 60 countries are implementing mandatory folic acid fortification of staple foods, preventing just a quarter of all preventable NTD cases worldwide. There is an urgent need for active champions, including neurosurgeons and other healthcare providers, to generate political will and promote effective mandatory food fortification with folic acid, and reach equitable primary prevention of NTDs in all countries.

A case study of ReachAnother Foundation as a change champion for developing spina bifida neurosurgical care and advocating for primary prevention in Ethiopia.

Spina bifida is a serious birth defect affecting the central nervous system, characterized by incomplete closure of the neural tube. Ethiopia has a very high prevalence of spina bifida, affecting about 40 cases per 10,000 births. Babies born with spina bifida require early closure surgery, done within the first 2-3 days after birth. Some babies need repeat surgeries to address complications, including hydrocephalus. Without medical care, babies have a high risk of death within the first 5 years of their life. Neurosurgical capacity for spina bifida closure surgery at birth is a relatively new development in Ethiopia. ReachAnother Foundation, a not-for-profit organization based in OR, USA, started work in Ethiopia in 2009 and has been instrumental in training neurosurgeons and improving treatment for spina bifida and hydrocephalus. Along with the development of neurosurgical care, the Foundation has invested in training multi-disciplinary teams to conduct patient aftercare and has launched a platform for improved patient outcomes research. As of year 2022, they support six spina bifida "Centers of Excellence" nationwide and are continuously advocating for primary prevention of spina bifida through mandatory fortification of staple foods in Ethiopia. This paper describes ReachAnother's efforts in Ethiopia in a short interval of time, benefiting numerous patients and families with spina bifida and anencephaly. We document this as a case study for other countries to model where resources are limited and the prevalence of spina bifida and hydrocephalus is high, especially in Asia and Africa.

National Mandatory Grain Fortification Legislation Decreases Anemia Prevalence among Nonpregnant Women of Reproductive Age: Findings from Multiple Demographic and Health Surveys.

BACKGROUND: Two billion people are affected by anemia globally, mostly including women of reproductive age (WRA) and those residing in low- and middle-income countries (LMICs). Large national population-representative studies examining the impact of national grain fortification policies on the prevalence of anemia among WRA are lacking from recent years. OBJECTIVES: We aimed to determine whether mandatory national grain fortification policies reduce the prevalence of anemia among nonpregnant WRA. METHODS: We examined national food fortification policy characteristics from the Global Fortification Data Exchange (GFDx) database and anemia prevalence data from the Demographic and Health Surveys (DHSs). In total, 21 LMICs, with and without national grain fortification policies, completing ≥2 DHSs between 2000 and 2018, met study eligibility. We applied the difference-in-differences approach to compare changes in the prevalence of anemia among WRA in 10 countries with and 11 countries without fortification between each DHS year. Odds ratios (ORs) and average marginal effects, along with 95% confidence intervals (CIs) were calculated, adjusting for individual-, household-, and country-level factors. RESULTS: Our analytic study sample included 96,334 and 874,984 WRA in countries with and without fortification, respectively. Overall, countries with fortification showed 27% decreased odds of anemia (adjusted OR: 0.73; 95% CI: 0.63, 0.85) and a 7.47-percentage-point decrease in the mean anemia prevalence (average marginal effect: -7.47; 95% CI: -11.03, -3.92) from the pre- to the postfortification period, compared with countries without fortification, after controlling for selected individual-, household-, and country-level factors. CONCLUSIONS: Our findings, using nationally representative DHS data and applying a recommended analytic method to measure policy effectiveness, suggest significant reductions in anemia prevalence in WRA in countries with mandatory grain fortification compared with those without. Implementing national mandatory grain fortification in LMICs would effectively reduce anemia resulting from micronutrient deficiencies among WRA.

The role of neurosurgeons in global public health: the case of folic acid fortification of staple foods to prevent spina bifida.

OBJECTIVE: The global neurosurgery movement arose at the crossroads of unmet neurosurgical needs and public health to address the global burden of neurosurgical disease. The case of folic acid fortification (FAF) of staple foods for the prevention of spina bifida and anencephaly (SBA) represents an example of a new neurosurgical paradigm focused on public health intervention in addition to the treatment of individual cases. The Global Alliance for the Prevention of Spina Bifida-F (GAPSBiF), a multidisciplinary coalition of neurosurgeons, pediatricians, geneticists, epidemiologists, food scientists, and fortification policy experts, was formed to advocate for FAF of staple foods worldwide. This paper serves as a review of the work of GAPSBiF thus far in advocating for universal FAF of commonly consumed staple foods to equitably prevent SBA caused by folic acid insufficiency. METHODS: A narrative review was performed using the PubMed and Google Scholar databases. RESULTS: In this review, the authors describe the impact of SBA on patients, caregivers, and health systems, as well as characterize the multifaceted requirements for proper spina bifida care, including multidisciplinary clinics and the transition of care, while highlighting the role of neurosurgeons. Then they discuss prevention policy approaches, including supplementation, fortification, and hybrid efforts with folic acid. Next, they use the example of FAF of staple foods as a model for neurosurgeons' involvement in global public health through clinical practice, research, education and training, and advocacy. Last, they describe mechanisms for involvement in the above initiatives as a potential academic tenure track, including institutional partnerships, organized neurosurgery, neurosurgical expert groups, nongovernmental organizations, national or international governments, and multidisciplinary coalitions. CONCLUSIONS: The role of neurosurgeons in caring for children with spina bifida extends beyond treating patients in clinical practice and includes research, education and training, and advocacy initiatives to promote context-specific, evidence-based initiatives to public health problems. Promoting and championing FAF serves as an example of the far-reaching, impactful role that neurosurgeons worldwide may play at the intersection of neurosurgery and public health.

A global update on the status of prevention of folic acid-preventable spina bifida and anencephaly in year 2020: 30-Year anniversary of gaining knowledge about folic acid's prevention potential for neural tube defects.

BACKGROUND: Spina bifida and anencephaly are major neural tube defects largely preventable through maternal periconceptional intake of folic acid. We estimated the global proportion of folic acid-preventable spina bifida and anencephaly (FAP SBA) prevented through mandatory folic acid fortification of cereal grains, including wheat flour, maize flour, and rice, at the end of year 2020, a time point marking the 30th anniversary of the publication of landmark British Medical Research Council (MRC) study providing unequivocal knowledge on folic acid's FAP SBA prevention potential. METHODS: The Food Fortification Initiative database was used to identify countries with mandatory fortification policies with folic acid added to cereal grains. We examined the status of FAP SBA prevention assuming mandatory folic acid fortification at 200 mcg/day of folic acid protects against FAP SBA and reduces their prevalence to a minimum achievable rate of 0.5 cases/1000 live births. RESULTS: Our analysis showed that 61,680 FAP SBA cases were prevented in the year 2020 through mandatory folic acid fortification of cereal grains in 58 countries, translating to 22% prevention of total possible FAP SBA prevention globally. Many countries in Africa, Asia, and Europe are yet to implement fortification. In 2020, 30 years after the MRC study was published, 218,270 preventable FAP SBA cases still occurred globally. CONCLUSION: Global prevention efforts for FAP SBA are inadequate even after three decades of knowledge on their prevention. Universal mandatory fortification of staples should be urgently implemented to prevent thousands of FAP SBA and associated elective terminations, stillbirths, and child mortality.

Preventing birth defects, saving lives, and promoting health equity: an urgent call to action for universal mandatory food fortification with folic acid.

July 20, 2021 marked the 30th anniversary of the publication of the landmark trial by the British Medical Research Council showing unequivocally that maternal intake of folic acid (vitamin B9) starting before pregnancy prevents most cases of infant spina bifida and anencephaly-two major neural tube defects that are severe, disabling, and often fatal. Mandatory food fortification with folic acid is a safe, cost-effective, and sustainable intervention to prevent spina bifida and anencephaly. Yet few countries implement fortification with folic acid; only a quarter of all preventable spina bifida and anencephaly cases worldwide are currently avoided by food fortification. We summarise scientific evidence supporting immediate, mandatory fortification with folic acid to prevent the development of spina bifida and anencephaly. We make an urgent call to action for the World Health Assembly to pass a resolution for universal mandatory folic acid fortification. Such a resolution could accelerate the slow pace of spina bifida and anencephaly prevention globally, and will assist countries to reach their 2030 Sustainable Development Goals on child mortality and health equity. The cost of inaction is profound, and disproportionately impacts susceptible populations in low-income and middle-income countries.

Food Fortification With Folic Acid for Prevention of Spina Bifida and Anencephaly: The Need for a Paradigm Shift in Evidence Evaluation for Policy-Making.

Context-specific evidence evaluation is advocated in modern epidemiology to support public health policy decisions, avoiding excessive reliance on experimental study designs. Here we present the rationale for a paradigm shift in evaluation of the evidence derived from independent studies, as well as systematic reviews and meta-analyses of observational studies, applying Hill's criteria (including coherence, plausibility, temporality, consistency, magnitude of effect, and dose-response) to evaluate food fortification as an effective public health intervention against folic acid-preventable (FAP) spina bifida and anencephaly (SBA). A critical appraisal of evidence published between 1983 and 2020 supports the conclusion that food fortification with folic acid prevents FAP SBA. Policy-makers should be confident that with mandatory legislation, effective implementation, and periodic evaluation, food fortification assures that women of reproductive age will safely receive daily folic acid to significantly reduce the risk of FAP SBA. Current evidence should suffice to generate the political will to implement programs that will save thousands of lives each year in over 100 countries.

Reducing the Burden of Anemia and Neural Tube Defects in Low- and Middle-Income Countries: An Analysis to Identify Countries with an Immediate Potential to Benefit from Large-Scale Mandatory Fortification of Wheat Flour and Rice.

Using a predetermined set of criteria, including burden of anemia and neural tube defects (NTDs) and an enabling environment for large-scale fortification, this paper identifies 18 low- and middle-income countries with the highest and most immediate potential for large-scale wheat flour and/or rice fortification in terms of health impact and economic benefit. Adequately fortified staples, delivered at estimated coverage rates in these countries, have the potential to avert 72.1 million cases of anemia among non-pregnant women of reproductive age; 51,636 live births associated with folic acid-preventable NTDs (i.e., spina bifida, anencephaly); and 46,378 child deaths associated with NTDs annually. This equates to a 34% reduction in the number of cases of anemia and 38% reduction in the number of NTDs in the 18 countries identified. An estimated 5.4 million disability-adjusted life years (DALYs) could be averted annually, and an economic value of 31.8 billion United States dollars (USD) generated from 1 year of fortification at scale in women and children beneficiaries. This paper presents a missed opportunity and warrants an urgent call to action for the countries identified to potentially avert a significant number of preventable birth defects, anemia, and under-five child mortality and move closer to achieving health equity by 2030 for the Sustainable Development Goals.

Projected impact of mandatory food fortification with folic acid on neurosurgical capacity needed for treating spina bifida in Ethiopia.

Spina bifida, also known as meningomyelocele, is a major birth defect mostly associated with folate deficiency in the mother early in pregnancy. The prevalence of spina bifida is disproportionately high in Ethiopia compared to the global average; about 10,500 liveborn are affected annually. Many affected infants do not receive timely repair surgery. There are a high number of stillbirths, and neonatal, infant, and under-five deaths. Mandatory fortification of staple foods such as wheat and maize flour with folic acid, a B vitamin, is an effective primary prevention strategy for spina bifida. Survival in those with spina bifida increases if neurosurgical intervention is available soon after birth, along with continuous surgical and clinical aftercare throughout the lifespan. Currently, Ethiopia does not have mandatory food fortification for primary prevention or adequate neurosurgical capacity to meet the need to prevent adverse outcomes associated with spina bifida. We present in this paper two concurrent and complementary policy and practice solutions occurring in Ethiopia through global partnerships: (1) capacity-building of neurosurgery care through training programs; and (2) promoting national mandatory folic acid fortification of staples for primary prevention of spina bifida. These two policy and practice interventions ensure all affected infants can receive timely pediatric neurosurgery and sustained surgical aftercare through required neurosurgeon availability, and ensure primary prevention of spina bifida. Primary prevention of spina bifida frees up significant neurosurgical capacity in resource-poor settings that can then be directed to other critical neurosurgical needs thus lowering child mortality and morbidity.

A 2019 global update on folic acid-preventable spina bifida and anencephaly.

BACKGROUND: Mandatory folic acid fortification of staples is a proven intervention to prevent spina bifida and anencephaly, two life-threatening and disabling neural tube defects. We estimated the global proportion of folic acid-preventable spina bifida and anencephaly (FAP SBA) prevented through mandatory folic acid fortification of wheat and/or maize flour in 2019. METHODS: Using data from the Global Fortification Data Exchange, we identified countries with mandatory fortification policies that required at least 1.0 ppm folic acid be added to wheat and/or maize flour and had information on percentage of industrially milled flour that is fortified. We built FAP SBA prevention models assuming mandatory folic acid fortification at 200 µg/day of folic acid fully protects against FAP SBA and would lower the prevalence neural tube defects to 0.5 per 1,000 live births. RESULTS: In 2019, 56 countries met our criteria for mandatory folic acid fortification of wheat (n = 56 countries) and/or maize (n = 15 countries) flour and with complete data for our modeling. Overall, our prevention model estimated that 65,380 FAP SBA cases were prevented in 2019 through folic acid fortification of wheat and/or maize flour. We estimated the current global prevention proportion of all preventable FAP SBA cases worldwide to be at 23% of total possible prevention. CONCLUSION: Global prevention efforts for FAP SBA are slow and have stalled. Mandatory fortification should be urgently implemented in all countries to prevent epidemics of FAP SBA, and to achieve health-related Sustainable Development Goals for year 2030 by reducing child mortality due to preventable FAP SBA.

Modeling shows high potential of folic acid-fortified salt to accelerate global prevention of major neural tube defects.

BACKGROUND: We estimated the global proportion of folic acid-preventable spina bifida and anencephaly (FAP SBA) potentially prevented through mandatory double fortification of iodized salt with folic acid. METHODS: Using United Nations Children's Fund (UNICEF) and Global Fortification Data Exchange (GFDx) data sets, we modeled country-specific number of FAP SBA cases prevented annually using (a) current coverage of the salt in households worldwide and (b) expected daily amount of folic acid intake from folic acid-fortified iodized salt. Our evidence-based modeling strategy assumed mandatory folic acid fortification of salt at 20 ppm, and that at 200 µg/day intake of folic acid through fortified salt, should achieve 100% prevention of all FAP SBA in countries. RESULTS: One hundred countries that have data on percent of households consuming iodized salt globally were examined; 55 of them have ≥80% households consuming iodized salt. Our model estimated approximately 180,000 cases of FAP SBA could be prevented in these 100 countries through folic acid-fortified iodized salt, and 150,000 of them would be in countries where ≥80% households consuming iodized salt that can be potentially fortified with folic acid. Salt fortification with folic acid could contribute to the prevention of about 65% global FAP SBA cases annually. CONCLUSIONS: Our evidence-based model shows that there is high potential to prevent FAP SBA using folic acid-fortified iodized salt. Prevention will reach countries where there is a limited reach of centrally processed folic acid-fortified wheat or maize flour. If this intervention is made feasible by the salt industry, it can accelerate the prevention of FAP SBA significantly.

The Fallacy of Using Administrative Data in Assessing the Effectiveness of Food Fortification. Comment on: "Folic Acid Fortification and Neural Tube Defect Risk: Analysis of the Food Fortification Initiative Dataset. Nutrients 2020, 12, 247".

Our objective in this comment is to highlight several limitations in an ecological research study that was published in Nutrients by Murphy and Westmark (2020) in January 2020. The study used data from the Food Fortification Initiative (FFI) website, and applying an ecological study design, made an error of "ecologic fallacy" in concluding that "national fortification with folic acid is not associated with a significant decrease in the prevalence of neural tube defects (NTDs) at the population level". We list study limitations that led to their erroneous conclusions, stemming from incorrect considerations regarding NTD prevalence, the average grain availability for a country, the fortification coverage in a country, the population reach of fortified foods within a country, and the absence of the consideration of fortification type (voluntary vs. mandatory), country-specific policies on elective terminations for NTD-affected pregnancies, stillbirth proportions among those with NTDs, and fortification implementation. FFI data are derived from many sources and intended for fortification advocacy, not for hypothesis testing. The flawed study by Murphy & Westmark (2020) in Nutrients promotes a confusing and incorrect message to stakeholders, misguides policy makers, and hinders progress in global NTD prevention through a cost-effective, safe, and effective intervention: the mandatory large-scale folic acid fortification of staple foods.

Periconceptional folic acid supplement use among women of reproductive age and its determinants in central rural Germany: Results from a cross sectional study.

BACKGROUND: Prevalence of neural tube defects (NTD) has not decreased in Germany despite longstanding recommendations for folic acid supplementation. To examine the prevalence of periconceptional folic acid supplement use and associated factors among German women of reproductive age. METHODS: Cross-sectional survey was conducted in hospital-based maternity units in rural Germany. A sample of 1,004 women of reproductive age, either pregnant or in their early postpartum period, took interviewer/self-administered paper-based survey questionnaire. Prevalence of periconceptional folic acid supplement use was assessed, where periconception was defined as 1 month prior to and 3 months post-conception. Prevalence odds ratios (POR) and 95% confidence intervals (CI) using crude and adjusted logistic regression analysis were estimated to examine determinants of folic acid supplement use. RESULTS: Prevalence of folic acid supplement use was 41.5% (95% CI: 37.7%, 45.7%). Multivariable analysis showed lack of educational qualifications, unplanned pregnancy, later diagnosis of pregnancy, increased parity, and not having an awareness of importance of folic acid for optimal pregnancy outcomes were associated with not taking periconceptional folic acid supplements. Books, doctors, friends, media, were sources of information. CONCLUSION: Periconceptional folic acid is sub-optimal in rural Germany and thus failing to prevent NTDs. Targeted promotion of folic acid supplement use should be conducted periodically by gynecologists and primary care physicians during annual medical screenings. Mandatory folic acid fortification of staple foods is a complementary approach to overcome limitations of individual behaviors of folic acid supplement intake, and should be considered as it has been proven effective in multiple countries.

High potential for reducing folic acid-preventable spina bifida and anencephaly, and related stillbirth and child mortality, in Ethiopia.

BACKGROUND: Recent surveillance studies in Ethiopia show an epidemic of spina bifida and anencephaly, two major neural tube birth defects that are severe and life-threatening. Our objective was to estimate proportional reductions in current stillbirth and child mortality rates in Ethiopia through folic acid-based interventions to prevent spina bifida and anencephaly. METHODS: Using secondary data from multiple sources, we estimated percent reductions in stillbirth, neonatal, infant, and under-five child mortality rates that would have occurred in Ethiopia in the year 2016 had all folic acid-preventable spina bifida and anencephaly been prevented; and the contributions of these reductions toward Ethiopia's Year 2030 Every Newborn Action Plan (ENAP) goal on stillbirth, and sustainable development goal (SDG) on child mortality rates. The 2016 prevalence of spina bifida and anencephaly in Ethiopia was assumed as 13 per 1,000 total births, with the prevention goal reaching 0.5 per 1,000 total births. RESULTS: Folic acid interventions in Ethiopia would have prevented about 41,610 cases of folic acid-preventable spina bifida and anencephaly-affected pregnancies during the year 2016. We estimate that this prevention is associated with reduction of 31,830 stillbirths and 7,335 under-five child deaths annually. The proportional contribution of this prevention toward achieving Ethiopia's ENAP goal is 54% for stillbirth, and toward SDG is 4.5% for neonatal- and 6.8% for under-five mortality. CONCLUSIONS: Spina bifida and anencephaly contribute to substantial stillbirths and child death in Ethiopia. Large-scale fortification of foods like wheat flour and salt can help achieve Ethiopia's ENAP and SDG targets addressing preventable stillbirth, neonatal, and under-five mortality.

Nation-wide failure of voluntary folic acid fortification of corn masa flour and tortillas with folic acid.

BACKGROUND: The United States Food and Drug Administration (FDA) required all enriched cereal grains to be fortified with folic acid in 1998. In April 2016, the FDA published regulations allowing voluntary fortification of corn masa flour with folic acid to address the high prevalence of folic acid-preventable spina bifida and anencephaly among Hispanics. Our objective was to survey folic acid-fortified corn masa and corn tortilla products in the country using a national social media campaign. METHODS: In January 2019, we conducted a social media campaign (#FindFolicAcid) engaging citizens nationwide to survey local stores for folic acid in corn masa flour and corn tortilla products. Photos of products and nutrition labels were shared with the researchers on various social media portals (e.g., Twitter, Facebook, and Instagram). The posts were summarized for a descriptive analysis. RESULTS: People from 28 states shared photos of 132 products, including 43 unique corn masa flour or corn tortilla products. Of those, only three corn masa flour products included folic acid: (a) Maseca Instant White (4.4 lb bag); (b) Masa Brosa Instant; and (c) Masa Brosa Instant Blue. None of the corn tortilla products were fortified. CONCLUSION: There is a failure of voluntary folic acid fortification of corn masa flour and products nationally. Until folic acid fortification of corn masa products is implemented fully in the country, Hispanic women of reproductive age should take a daily vitamin supplement which includes at least 400 mcg of folic acid to prevent spina bifida and anencephaly.

Reductions in child mortality by preventing spina bifida and anencephaly: Implications in achieving Target 3.2 of the Sustainable Development Goals in developing countries.

BACKGROUND: There is an opportunity to reduce child mortality by preventing folic acid-preventable spina bifida and anencephaly (FAP SBA) in developing countries. We estimated reductions in FAP SBA-associated child mortality in 69 countries with an immediate potential for mandatory fortification of wheat flour. METHODS: Using data from multiple sources, we estimated the percent reductions in neonatal, infant, and under-five mortality that would have occurred by preventing FAP SBA; and the contributions of these reductions toward each country's Sustainable Development Goals (SDG) for child mortality reduction. We used the combined prevalence of spina bifida and anencephaly in selected countries before fortification, and estimated preventable child mortality associated with FAP SBA, assuming 0.5 per 1,000 live births as minimum achievable prevalence from mandatory fortification. RESULTS: Annually, 56,785 live births with FAP SBA occurred in the 69 countries examined. Of these, about 49,680 (87%) would have resulted in deaths under age 5 years, and are preventable through mandatory folic acid fortification. On average, compared to current rates, prevention of FAP SBA would have reduced the neonatal, infant, and under-five mortality by 19% (95% uncertainty interval [UI]: 16-24%), 15% (UI: 13-17%), and 14%, (95% UI: 13-17%), respectively. Prevention of FAP SBA seemed to contribute toward achieving SDG on neonatal and under-five mortality in developing countries. CONCLUSIONS: Prevention of FAP SBA will lead to notable and immediate reductions in child mortality. Many countries have an opportunity to effectively move toward child mortality-related SDG targets with existing milling infrastructure for food fortification.
