Close to 8 million children are born annually with a serious birth defect, accounting for 5% of all newborn deaths globally. Many birth defects are associated with folic acid insufficiency, non-communicable diseases (NCDs), teenage or advanced age pregnancies, short birth intervals, and exposure to harmful substances. The majority of countries with the highest birth defects prevalence are in Africa, and the East African Community has made important commitments to improving reproductive, child, and adolescent health and nutrition. The aim of this review was to identify the advances and gaps in national policies addressing birth defect risk factors in the East African Community (Burundi, Kenya, Rwanda, Tanzania, and Uganda) in order to inform additional actions. National laws, regulations and policies were reviewed from the East African Community countries related to grain fortification and supplementation with folic acid; reducing too-early, unwanted and rapid successive pregnancies; and addressing NCDs and exposure to tobacco. All five countries have adopted a policy of mandatory folic acid fortification of wheat and maize flour. However, only in Kenya and Tanzania, are the folic acid levels in line with international recommendations. And, only Uganda has a policy requiring folic acid supplementation administration in the preconceptional period. The East African Community countries have made efforts to reduce too-early, unwanted and rapid successive pregnancies. All countries have banned child marriage and three of five countries have introduced laws to allow unrestricted access to contraception for adolescents. With regards to promoting prevention and control of NCDs and reducing populations' exposure, compliance with World Health Organization (WHO) guidelines is limited. Only two countries have developed multi-sectoral policies for NCDs and no countries comply fully with the recommendations of the Framework Convention on Tobacco Control. Much work remains in ensuring that opportunities for prevention of birth defects are fully realized in the East African Community countries. This review revealed that all countries in the East African Community have, to some extent, adopted policies that are conducive to reducing the risk of birth defects in the region, but significant gaps remain in some key areas of either policy development or implementation.

Household Consumption and Expenditure Surveys (HCES) are increasingly used to estimate the potential of food fortification programs. Senegal's latest HCES, Enquête de Suivi de la Pauvreté au Sénégal, was completed in 2011. As no Senegalese food composition table exists, one had to be constructed to analyze Senegal's HCES, which contains 50 foods or food groups. These are millet, sorghum, maize, fonio, millet porridge, whole rice, broken rice, red rice, groundnut, peanut paste, groundnut paste, palm oil, vegetable oil, groundnut oil, soya oil, tomato paste, cabbage, tomato, onion, dried cowpea, bouillon cube, mango, fried egg sandwich, salt, herring, smoked catfish, dried whitefish, beef, goat, lamb, pork, chicken, sugar, coffee bean, instant coffee, green tea, hibiscus tea, Coca Cola, baobab fruit, beer, baguette, croissant, water biscuit, yoghurt, powder milk, milk, and gruyere cheese. A food composition table was constructed with 13 micronutrients (biotin, folate, iodine, iron, niacin, pantothenic acid, riboflavin, thiamin, vitamin A, vitamin B6, vitamin B12, vitamin D, and zinc) for the 50 food items in the Household Consumption and Expenditure Survey. Nutrient information was collected from the Table de Composition des Aliments d'Afrique de l'Ouest, United States Department of Agriculture's Food Composition Databases, Frida Fooddata, several journals, and books. In the survey, there were food groups such as alcoholic beverages that needed to be reclassified as a specific food, such as beer, to construct the food composition table. To accomplish this, food balance sheet data from the Food and Agriculture Organization of the United Nations were used as well as information from a Senegalese key informant. To consider the potential impact of food fortification on apparent nutrient intakes, nutrient information for ten fortified foods (bouillon cube, salt, palm oil, vegetable oil, groundnut oil, soya oil, and four wheat flour-containing foods such as baguette, croissant, water biscuit, and fried egg sandwich) were also included in the food composition table. With the newly developed Senegalese food composition table, it is possible to analyze Senegal's 2011 HCES. [ABSTRACT FROM AUTHOR]

Background: Child undernutrition remains high in South Asian and sub-Saharan African countries. Rapid declines in nutritional status occur before the age of 2 years, particularly during the period of complementary feeding. Improving complementary feeding practices is a neglected area in nutrition programs.Objective: To understand community perspectives on complementary feeding practices in order to inform the design of future interventions for improved complementary feeding.Methods: From May through August 2009, data were collected in two rural locations and one urban location in Bangladesh through semistructured interviews, food attributes exercises, 24-hour dietary recalls, opportunistic observations, and trials of improved practices (TIPs). Key informant interviews and focus group discussions were also carried out among family members and community opinion leaders.Results: Lay perceptions about complementary feeding differ substantially from international complementary feeding recommendations. A large proportion of children do not consume sufficient amounts of complementary foods to meet their energy and micronutrient needs. There was a gap in knowledge about appropriate complementary foods in terms of quality and quantity and strategies to convert family foods to make them suitable for children. Complementary feeding advice from family members, peers, and health workers, the importance given to feeding young children, and time spent by caregivers in feeding influenced the timing, frequency, types of food given, and ways in which complementary feeding occurred.Conclusions: Perceptions and practices related to complementary feeding need to be effectively addressed to improve the levels of child undernutrition. Lack of understanding of children's nutritional needs and insufficient time for feeding children are key barriers to complementary feeding. [ABSTRACT FROM AUTHOR]

Food fortification can deliver essential micronutrients to populations at a large scale, thereby reducing nutritional anemia. This study aimed to review and meta-analyze the literature on the impact of wheat flour, maize flour, rice, and oil (singly or combined) fortification on women's (10-49 years) hemoglobin and anemia. A search of 17 databases yielded 2284 results. Longitudinal, pre-post cross-sectional, efficacy, and effectiveness studies were included. Primary outcomes were changes in hemoglobin concentration and anemia prevalence. Studies were synthesized using arm-based network meta-analysis. In women who consumed fortified rice, hemoglobin mean change was 3.24 g/L (95% credibility interval (CrI) 0.9, 5.98), higher than for women in the control, with a 99.1% probability that the true mean difference was > 0. Hemoglobin was 2.08 g/L (95% CrI -0.76, 4.35) higher in women who consumed wheat flour versus control, with a 93.5% probability that the true mean difference was > 0. After rice fortification, anemia prevalence in women was 1.38 percentage points (95% CrI -106.6, 99.2) lower than for control women, with a 51.2% probability that the true mean difference was < 0. Wheat flour fortification decreased anemia prevalence by 1.84 percentage points (95% CrI -93.4, 92.4) with a 52.72% probability that the true mean difference was < 0. The treatment effects of fortified maize flour and fortified oil could not be calculated due to the absence of control arms compared to the intervention arms. Fortified rice and wheat flour appear likely to modestly increase hemoglobin and may also reduce anemia in women of childbearing age., (© 2025 The Author(s).

To reduce micronutrient deficiencies, Senegal mandates the fortification of refined oil with vitamin A and wheat flour with iron and folic acid. Expanding Senegal's large-scale food fortification programs to include fortified bouillon could help fill the remaining gaps in dietary micronutrient requirements. Using 7-day household food consumption data collected between 2018 and 2019, we assessed the potential contributions of bouillon fortified with vitamin A (40-250 μg/g bouillon), folic acid (20-120 μg/g), vitamin B12 (0.2-2 μg/g), iron (0.6-5 mg/g), and zinc (0.6-5 mg/g) for meeting micronutrient requirements of women of reproductive age (WRA; 15-49 years old) and children (6-59 months old). Most households (90%) reported consuming bouillon, including poor and rural households. At modeled fortification levels, bouillon fortification reduced the national prevalence of inadequacy by up to ∼20 percentage points (pp) for vitamin A, 34 pp (WRA) and 20 pp (children) for folate, 20 pp for vitamin B12, 38 pp (WRA) and 30 pp (children) for zinc, and ∼8 pp for iron. Predicted reductions in inadequacy were generally larger among poor and rural populations, especially for vitamins A and B12. Our modeling suggests that bouillon fortification has the potential to substantially reduce dietary inadequacy of multiple micronutrients and could also help address inequities in dietary micronutrient inadequacies in Senegal., (© 2024 The Author(s).

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., (© 2024 Wiley Periodicals LLC.)

(1) Background: Fortifying maize and wheat flours with folic acid has effectively reduced neural tube defect-affected births. However, maize and wheat flours may not be widely consumed in all countries; further reduction in neural tube defect-affected births could benefit from the identification of alternative food vehicles. We aimed to use dietary intake or apparent consumption data to determine alternative food vehicles for large-scale fortification with folic acid in low-income and lower-middle-income countries (LILMICs) and identify current research related to examining the technological feasibility of fortifying alternative foods with folic acid. (2) Methods: We identified 81 LILMICs, defined by the World Bank's (WB) 2018 income classifications. To identify dietary intake or apparent consumption, we reviewed WB's Microdata Library and Global Health Data Exchange for national surveys from 1997-2018. We reviewed survey reports for dietary intake or apparent consumption data and analyzed survey datasets for population coverage of foods. We defined alternative food vehicles as those that may cover/be consumed by ≥30% of the population or households; cereal grains (maize and wheat flours and rice) were included as an alternative food vehicle if a country did not have existing mandatory fortification legislation. To identify current research on fortification with folic acid in foods other than cereal grains, we conducted a systematic review of published literature and unpublished theses, and screened for foods or food products. (3) Results: We extracted or analyzed data from 18 national surveys and countries. The alternative foods most represented in the surveys were oil ( n = 16), sugar ( n = 16), and salt ( n = 14). The coverage of oil ranged from 33.2 to 95.7%, sugar from 32.2 to 98.4%, and salt from 49.8 to 99.9%. We found 34 eligible studies describing research on alternative foods. The most studied alternative foods for fortification with folic acid were dairy products ( n = 10), salt ( n = 6), and various fruit juices ( n = 5). (4) Conclusions: Because of their high coverage, oil, sugar, and salt emerge as potential alternative foods for large-scale fortification with folic acid. However, except for salt, there are limited or no studies examining the technological feasibility of fortifying these foods with folic acid.

Background: Maternal folate and vitamin B 12 deficiency can lead to serious adverse pregnancy outcomes. There are no nationally representative estimates on folate and vitamin B 12 status among women of reproductive age (WRA) in Malawi., Objective: We assessed folate and vitamin B 12 status among nonpregnant WRA in Malawi and predicted the risk of folate-sensitive neural tube defects (NTDs) were they to become pregnant., Methods: Using data from the cross-sectional, nationally representative 2015-2016 Malawi Micronutrient Survey, we calculated the proportion of folate and vitamin B 12 deficiency and insufficiency by demographic characteristics among 778 nonpregnant WRA (15-49 years). We predicted NTD prevalence using red blood cell (RBC) folate distributions and a published Bayesian model of the association between RBC folate and NTD risk. Analyses accounted for complex survey design., Results: Among WRA, 8.5% (95% CI: 6.2, 11.6) and 13.3% (10.0, 17.4) had serum (<7 nmol/L) and RBC folate (<305 nmol/L) deficiency, respectively. The proportion of vitamin B 12 deficiency (<148 pmol/L) and insufficiency (≤221 pmol/L) was 11.8% (8.6, 16.0) and 40.6% (34.1, 47.4), respectively. RBC folate insufficiency (<748 nmol/L, defined as the concentration associated with the threshold for elevated NTD risk: >8 cases per 10,000 births) was widespread: 81.4% (75.0, 86.4). The predicted NTD risk nationally was 24.7 cases per 10,000 live births. RBC folate insufficiency and higher predicted NTD risk were more common among WRA living in urban areas or with higher education., Conclusions: These findings highlight the importance of nutritional and NTD surveillance in Malawi and the opportunity for improving folate and vitamin B 12 nutrition among Malawian WRA., (© 2024 Wiley Periodicals LLC.

Anemia is a multifactorial condition; approaches to address it must recognize that the causal factors represent an ecology consisting of internal (biology, genetics, and health) and external (social/behavioral/demographic and physical) environments. In this paper, we present an approach for selecting interventions, followed by a description of key issues related to the multiple available interventions for prevention and reduction of anemia. We address interventions for anemia using the following 2 main categories: 1) those that address nutrients alone, and, 2) those that address nonnutritional causes of anemia. The emphasis will be on interventions of public health relevance, but we also consider the clinical context. We also focus on interventions at different stages of the life course, with a particular focus on women of reproductive age and preschool-age children, and present evidence on various factors to consider when selecting an intervention-inflammation, genetic mutations, nutrient delivery, bioavailability, and safety. Each section on an intervention domain concludes with a brief discussion of key research areas., (Copyright © 2023 The Authors. Published by Elsevier Inc. All rights reserved.)

Iodine deficiency is a public health problem in the US, with the iodine status of women of reproductive age decreasing in recent years. This may be attributable to voluntary salt iodization in the US. Magazines, a common source of recipes and nutritional information, may influence salt use and iodine intake. The aim of this study is to assess whether the magazines with the highest circulation in the US include recipes that contain salt and, if so, whether they specify "iodized salt" in the recipes. Recipes in eight of the top ten magazines by circulation in the US were examined. Standardized information was collected on the presence and type of salt in recipes in the last 12 issues reviewed per magazine. About 73% of the 102 issues reviewed contained recipes. A total of 1026 recipes were surveyed for salt; 48% of the recipes listed salt as an ingredient. None of the 493 recipes containing salt specified iodized salt as the type of salt to be used. About half of the recipes in the last 12 issues of popular magazines published in the US included salt in the ingredient list; however, none recommend the use of iodized salt. There is potential for editorial changes among magazines to call for iodized salt in recipes, which may further prevent iodine deficiency in the US.

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 Author(s) 2022.

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., (© 2022 Wiley Periodicals LLC.)

Background: Food fortification is the addition of 1 or more micronutrients to commonly consumed foods and is utilized by many countries as a public health intervention to prevent and control micronutrient deficiencies. As iodine deficiency was a major public health issue globally, the WHO developed evidence-based guidelines for the fortification of salt with iodine. The implementation of salt iodization has been highly successful in reducing iodine deficiency disorders worldwide and is recommended as the main strategy to prevent iodine deficiency., Objectives: This analysis compared salt iodization requirements specified in countries' salt standards with WHO 2014 Guidelines on salt fortification., Methods: For countries with mandatory salt iodization legislation, data from the Global Fortification Data Exchange regarding iodine amounts and iodine compounds, to be added to salt per the country standard and corresponding national salt intake quantities, were compared with 2014 WHO Guidelines., Results: As of 4 September 2021, 110 countries with mandatory salt iodization legislation had national salt standards that specified iodine amounts and compounds and salt intake data. All but 1 specified at least 1 recommended iodine compound, but the majority specified higher iodine amounts in salt standards than indicated in the guidelines, taking salt consumption levels into account. Our analysis did not find excess iodine intake as a result; however, we did not have data on the extent of compliance with national salt standards., Conclusions: Existing iodization requirements in salt standards appear to be appropriate for most countries. Countries in which iodine amounts in salt standards are significantly higher than those recommended in the 2014 Guidelines, in particular those with low compliance with national standards or excess iodine intake, may wish to review program process and output indicators and assess whether current iodine amounts in standards would result in excessive intake if implementation was improved., (© The Author(s) 2022.

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., (©The Author(s) 2021.

Food fortification is designed to improve the nutritional profile of diets. The purpose of this research was to estimate the potential nutrient contribution of fortified maize flour, oil, rice, salt, and wheat flour in 153 countries, using the national intake (or availability) of the food and the nutrient levels required for fortification. This was done under two scenarios-maximum, where 100% of the food is assumed to be industrially processed and fortified, and realistic, where the maximum value is adjusted based on the percent of the food that is industrially processed and fortified. Under the maximum scenario, the median Estimated Average Requirements (EARs) met ranged from 22-75% for 14 nutrients (vitamins A, B1, B2, B3, B6, B12, D, E, folic acid and calcium, fluoride, iron, selenium and zinc), and 338% for iodine. In the realistic scenario, the median EARs met were 181% for iodine and <35% for the other nutrients. In both scenarios, the median Tolerable Upper Intake Levels (ULs) met were <55% for all nutrients. Under the realistic scenario, no country exceeded 100% of the UL for any nutrient. Current fortification practices of the five foods of interest have the global potential to contribute up to 15 nutrients to the diets of people, with minimal risk of exceeding ULs.

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., (© 2020 Wiley Periodicals LLC.)

Background: Food fortification is implemented to increase intakes of specific nutrients in the diet, but contributions of fortified foods to nutrient intakes are rarely quantified., Objectives: We quantified iron, vitamin A, and iodine intakes from fortified staple foods and condiments among women of reproductive age (WRA)., Methods: In subnational (Nigeria, South Africa) and national (Tanzania, Uganda) cross-sectional, clustered household surveys, we assessed fortifiable food consumption. We estimated daily nutrient intakes from fortified foods among WRA by multiplying the daily apparent fortifiable food consumption (by adult male equivalent method) by a fortification content for the food. Two fortification contents were used: measured, based on the median amount quantified from individual food samples collected from households; and potential, based on the targeted amount in national fortification standards. Results for both approaches are reported as percentages of the estimated average requirement (EAR) and recommended nutrient intake (RNI)., Results: Fortified foods made modest contributions to measured iron intakes (0%-13% RNI); potential intakes if standards are met were generally higher (0%-65% RNI). Fortified foods contributed substantially to measured vitamin A and iodine intakes (20%-125% and 88%-253% EAR, respectively); potential intakes were higher (53%-655% and 115%-377% EAR, respectively) and would exceed the tolerable upper intake level among 18%-56% of WRA for vitamin A in Nigeria and 1%-8% of WRA for iodine in Nigeria, Tanzania, and Uganda., Conclusions: Fortified foods are major contributors to apparent intakes of vitamin A and iodine, but not iron, among WRA. Contributions to vitamin A and iodine are observed despite fortification standards not consistently being met and, if constraints to meeting standards are addressed, there is risk of excessive intakes in some countries. For all programs assessed, nutrient intakes from all dietary sources and fortification standards should be reviewed to inform adjustments where needed to avoid risk of low or excessive intakes., (Copyright © The Author(s) on behalf of the American Society for Nutrition 2020.)

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.

Background: Colombia's mandatory wheat flour fortification program has yet to be evaluated., Objective: Examine associations between consumption of fortified wheat flour and low serum ferritin (LSF) and anemia prevalence., Materials and Methods: A secondary analysis of the 2005 national nutrition survey (ENSIN) was completed for 3988 children 2-4 y, 5669 children 5-12 y and 2053 non-pregnant women 13-49 y. The relationship between consumption (quartiles) of wheat flour containing food (WFCF) and LSF and anemia was examined using chi-square analyses and logistic regression models., Results: In unadjusted analyses, the prevalence of LSF was similar across all quartiles of WFCF consumption in all age groups. The highest prevalence of anemia was observed in the lowest WFCF consumption quartiles in all age groups, but was not significantly different in non-pregnant women 13-49 y. In adjusted models this relationship between WFCF and anemia remained for children 2-4 y when comparing the highest WFCF intake quartile with the lowest quartile (OR: 0.7, 95 % Cl: 0.6-0.9). No association between WFCF and LSF was observed in adjusted (or unadjusted) models., Conclusions: In Colombia, consumption of wheat flour containing foods is associated with lower levels of anemia in pre-school children., Competing Interests: CONFLICT OF INTEREST None.

Background: Folate is a B-vitamin required for DNA synthesis, methylation, and cellular division. Wheat and maize (corn) flour are staple crops consumed widely throughout the world and have been fortified with folic acid in over 80 countries to prevent neural tube defects. Folic acid fortification may be an effective strategy to improve folate status and other health outcomes in the overall population., Objectives: To evaluate the health benefits and safety of folic acid fortification of wheat and maize flour (i.e. alone or in combination with other micronutrients) on folate status and health outcomes in the overall population, compared to wheat or maize flour without folic acid (or no intervention)., Search Methods: We searched the following databases in March and May 2018: Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE and MEDLINE In Process, Embase, CINAHL, Web of Science (SSCI, SCI), BIOSIS, Popline, Bibliomap, TRoPHI, ASSIA, IBECS, SCIELO, Global Index Medicus-AFRO and EMRO, LILACS, PAHO, WHOLIS, WPRO, IMSEAR, IndMED, and Native Health Research Database. We searched the International Clinical Trials Registry Platform and ClinicalTrials.gov for ongoing or planned studies in June 2018, and contacted authors for further information., Selection Criteria: We included randomised controlled trials (RCTs), with randomisation at the individual or cluster level. We also included non-RCTs and prospective observational studies with a control group; these studies were not included in meta-analyses, although their characteristics and findings were described. Interventions included wheat or maize flour fortified with folic acid (i.e. alone or in combination with other micronutrients), compared to unfortified flour (or no intervention). Participants were individuals over two years of age (including pregnant and lactating women), from any country., Data Collection and Analysis: Two review authors independently assessed study eligibility, extracted data, and assessed risk of bias., Main Results: We included 10 studies: four provided data for quantitative analyses (437 participants); five studies were randomised trials (1182 participants); three studies were non-RCTs (1181 participants, 8037 live births); two studies were interrupted time series (ITS) studies (1 study population of 2,242,438, 1 study unreported). Six studies were conducted in upper-middle-income countries (China, Mexico, South Africa), one study was conducted in a lower-middle-income country (Bangladesh), and three studies were conducted in a high-income country (Canada). Seven studies examined wheat flour fortified with folic acid alone or with other micronutrients. Three studies included maize flour fortified with folic acid alone or with other micronutrients. The duration of interventions ranged from two weeks to 36 months, and the ITS studies included postfortification periods of up to seven years. Most studies had unclear risk of bias for randomisation, blinding, and reporting, and low/unclear risk of bias for attrition and contamination.Neural tube defects: none of the included RCTs reported neural tube defects as an outcome. In one non-RCT, wheat flour fortified with folic acid and other micronutrients was associated with significantly lower occurrence of total neural tube defects, spina bifida, and encephalocoele, but not anencephaly, compared to unfortified flour (total neural tube defects risk ratio (RR) 0.32, 95% confidence interval (CI) 0.21 to 0.48; 1 study, 8037 births; low-certainty evidence).Folate status: pregnant women who received folic acid-fortified maize porridge had significantly higher erythrocyte folate concentrations (mean difference (MD) 238.90 nmol/L, 95% CI 149.40 to 328.40); 1 study, 38 participants; very low-certainty evidence) and higher plasma folate (MD 14.98 nmol/L, 95% CI 9.63 to 20.33; 1 study, 38 participants; very low-certainty evidence), compared to no intervention. Women of reproductive age consuming maize flour fortified with folic acid and other micronutrients did not have higher erythrocyte folate (MD -61.80 nmol/L, 95% CI -152.98 to 29.38; 1 study, 35 participants; very low-certainty evidence) or plasma folate (MD 0.00 nmol/L, 95% CI -0.00 to 0.00; 1 study, 35 participants; very low-certainty evidence) concentrations, compared to women consuming unfortified maize flour. Adults consuming folic acid-fortified wheat flour bread rolls had higher erythrocyte folate (MD 0.66 nmol/L, 95% CI 0.13 to 1.19; 1 study, 30 participants; very low-certainty evidence) and plasma folate (MD 27.00 nmol/L, 95% CI 15.63 to 38.37; 1 study, 30 participants; very low-certainty evidence), versus unfortified flour. In two non-RCTs, serum folate concentrations were significantly higher among women who consumed flour fortified with folic acid and other micronutrients compared to women who consumed unfortified flour (MD 2.92 nmol/L, 95% CI 1.99 to 3.85; 2 studies, 657 participants; very low-certainty evidence).Haemoglobin or anaemia: in a cluster-randomised trial among children, there were no significant effects of fortified wheat flour flatbread on haemoglobin concentrations (MD 0.00 nmol/L, 95% CI -2.08 to 2.08; 1 study, 334 participants; low-certainty evidence) or anaemia (RR 1.07, 95% CI 0.74 to 1.55; 1 study, 334 participants; low-certainty evidence), compared to unfortified wheat flour flatbread., Authors' Conclusions: Fortification of wheat flour with folic acid may reduce the risk of neural tube defects; however, this outcome was only reported in one non-RCT. Fortification of wheat or maize flour with folic acid (i.e. alone or with other micronutrients) may increase erythrocyte and serum/plasma folate concentrations. Evidence is limited for the effects of folic acid-fortified wheat or maize flour on haemoglobin levels or anaemia. The effects of folic acid fortification of wheat or maize flour on other primary outcomes assessed in this review is not known. No studies reported on the occurrence of adverse effects. Limitations of this review were the small number of studies and participants, limitations in study design, and low-certainty of evidence due to how included studies were designed and reported.

Background: Solomon Islands (SI) mandated wheat flour fortification in 2010. Rice is a key staple food in SI, and its fortification may provide an opportunity to deliver additional micronutrients to the population., Objective: To determine whether fortified rice (proposed) and fortified wheat flour potentially benefit women of reproductive age (WRA)., Methods: We analyzed data from the 2012-2013 Household Income and Expenditure Survey to quantify food purchases, which served as a proxy for food consumption. We accounted for varied household composition by using adult male equivalent (AME) adjustments., Results: Among 4478 households, 95.6% purchased rice and 86.6% purchased at least 1 food containing fortified wheat flour in the previous 14 days. Median apparent intake of rice among WRA was 205 g/d/AME. If fortified according to proposed standards, this apparent intake could result in the consumption of 12.3 mg iron/d, fulfilling 44% of the estimated average requirement (EAR), and 226 µg folic acid/d, satisfying 57% of World Health Organization's recommended intake of 400 µg/d. Overall, apparent rice consumption could fulfill 113%, 114%, and 131% of the EAR for WRA for zinc, thiamin, and niacin, respectively. Fortified wheat flour was consumed in much lower quantities, with an estimated apparent median intake of 22 g/d/AME among WRA and 78 g/d/AME among women in urban populations., Conclusions: The potential benefit of fortified wheat flour in SI is likely limited to urban populations. Apparent consumption of fortified rice in SI could contribute considerably to daily intake of iron, B vitamins including folic acid, and zinc among WRA.

Objective: Analyze the content of documents used to guide mandatory fortification programs for cereal grains., Methods: Legislation, standards, and monitoring documents, which are used to mandate, provide specifications for, and confirm fortification, respectively, were collected from countries with mandatory wheat flour (n=80), maize flour (n=11), and/or rice (n=6) fortification as of January 31, 2015, yielding 97 possible country-grain combinations (e.g., Philippines-wheat flour, Philippines-rice) for the analysis. After excluding countries with limited or no documentation, 72 reviews were completed, representing 84 country-grain combinations. Based on best practices, a criteria checklist was created with 44 items that should be included in fortification documents. Two reviewers independently scored each available document set for a given country and food vehicle (a country-grain combination) using the checklist, and then reached consensus on the scoring. We calculated the percentage of country-grain combinations containing each checklist item and examined differences in scores by grain, region, and income level., Results: Of the 72 country-grain combinations, the majority of documentation came from countries in the Americas (46%) and Africa (32%), and most were from upper and lower middle-income countries (73%). The majority of country-grain combinations had documentation stating the food vehicle(s) to be fortified (97%) and the micronutrients (e.g., iron) (100%), fortificants (e.g., ferrous fumarate) (88%), and fortification levels required (96%). Most (78%) stated that labeling is required to indicate a product is fortified. Many country-grain combinations described systems for external (64%) monitoring, and stated that industry is required to follow quality assurance/quality control (64%), though detailed protocols (33%) and roles and responsibilities (45%) were frequently not described., Conclusions: Most country-grain combinations have systems in place for internal, external, and import monitoring. However, documentation of other important items that would influence product compliance to national standard, such as roles and responsibilities between agencies, the cost of regulating fortification, and enforcement strategies, are often lacking. Countries with existing mandatory fortification can improve upon these items in revisions to their documentation while countries that are beginning fortification can use the checklist to assist in developing new policies and programs., (© Marks et al.)

Background and Objectives: Consumption of foods made with wheat flour, particularly instant noodles, is increasing in Asia. Given this trend, fortifying wheat flour with vitamins and minerals may improve micronutrient intake in the region. The objective of this review was to understand what is known about fortifying wheat flour used to make instant noodles., Methods and Study Design: A literature review of seven databases was performed using the search terms "noodle" and ("Asian" or "instant"). Grey literature was requested through a food fortification listserv. Articles were title screened first for relevance and duplicity, with exclusion criteria applied during the second round of abstract-level screening. This review considered studies examining simulation, retention, sensory, bioavailability, efficacy, and effectiveness of instant noodles made with fortified wheat flour., Results: Fourteen relevant documents were reviewed for simulation (n=1), retention (n=11), and sensory studies (n=3). The documents revealed that instant noodles produced from fortified wheat flour have potential to improve nutrient intakes, have high retention of most nutrients, and provoke no or minimal changes in sensory characteristics., Conclusions: The available literature indicates that using fortified wheat flour for instant noodle production results in retention of the added nutrients, except thiamin, with no significant sensory change to the final product. Given the rising consumption of instant noodles, production of this item with fortified wheat flour has potential to improve nutrient intakes in Asia. This review provides a resource for the design of a wheat flour fortification program in countries where a large proportion of wheat flour is consumed as instant noodles.

Background: Fortification of cereal grains with at least iron or folic acid is legislated in 85 countries worldwide. Relative to wheat and maize flour, rice fortification is relatively new and provides an opportunity to deliver essential micronutrients to populations that consume rice as a dietary staple., Objective: To describe miller and public sector experiences and perspectives on rice fortification with micronutrients in Colombia and offer recommendations for policy makers., Methods: Interviews with Colombian rice millers, research and development personnel, and public sector leaders; desk review of key documents., Results: In Colombia, rice fortified with micronutrients is market driven and a few very large rice millers, currently representing about 35% of the market, have voluntarily fortified rice since 2002. The technology used (spraying) is unique to Colombia and to date there is no independent verification of nutrient retention after washing and cooking rice fortified through this technology. Millers are unwilling to switch to more proven methods, such as extrusion or coating, which will incur higher capital investment and recurring costs. Despite interest from multiple stakeholders between 2002 and 2011, mandatory rice fortification is not part of the Colombian government policy as of July 2015., Conclusion: Rice fortified with micronutrients through spraying technology has achieved moderate coverage in Colombia, but the technology is unproven, its effectiveness unknown, and public health impact likely limited. For rice fortification to be an effective nutrition intervention to improve micronutrient status, policy makers should explore standards to guide industry and improvements to regulatory capacity.

Background: Spina bifida and anencephaly are two major neural tube defects. They contribute substantially to perinatal, neonatal, infant, and under-five mortality and life-long disability. To monitor the progress toward the total prevention of folic acid-preventable spina bifida and anencephaly (FAP SBA), we examined their global status in 2015., Methods: Based on existing data, we modeled the proportion of FAP SBA that are prevented in the year 2015 through mandatory folic acid fortification globally. We included only those countries with mandatory fortification that added at least 1.0 ppm folic acid as a fortificant to wheat and maize flour, and had complete information on coverage. Our model assumed mandatory folic acid fortification at 200 μg/day is fully protective against FAP SBA, and reduces the rate of spina bifida and anencephaly to a minimum of 0.5 per 1000 births., Results: Our estimates show that, in 2015, 13.2% (35,500 of approximately 268,700 global cases) of FAP SBA were prevented in 58 countries through mandatory folic acid fortification of wheat and maize flour. Most countries in Europe, Africa, and Asia were not implementing mandatory fortification with folic acid., Conclusion: Knowledge that folic acid prevents spina bifida and anencephaly has existed for 25 years, yet only a small fraction of FAP SBA is being prevented worldwide. Several countries still have 5- to 20-fold epidemics of FAP SBA. Implementation of mandatory fortification with folic acid offers governments a proven and rapid way to prevent FAP SBA-associated disability and mortality, and to help achieve health-related Sustainable Development Goals.

Context: More than 80 countries fortify flour, yet the public health impact of this intervention on iron and anemia outcomes has not been reviewed., Objective: The objective of this systematic review was to review published and gray literature pertaining to the impact of flour fortification on iron and anemia., Data Sources: A systematic review was conducted by searching 17 databases and appealing for unpublished reports, yielding 1881 documents., Study Selection: Only studies of government-supported, widely implemented fortification programs in which anemia or iron status was measured prior to and ≥12 months after initiation of fortification were included., Data Extraction: Details about the design, coverage, compliance with national standards, and evaluation (e.g., anemia prevalence before and after fortification) of flour fortification programs were extracted from the reports., Data Synthesis: Thirteen studies describing 26 subgroups (n = 14 for children ≤15 y, n = 12 for women of reproductive age) were included. During the period from pre- to postfortification (and as difference-in-difference for those studies that included a control group), there were statistically significant decreases in the prevalence of anemia in 4 of 13 subgroups of children and in 4 of 12 subgroups of women of reproductive age as well as significant decreases in the prevalence of low ferritin in 1 of 6 subgroups of children and in 3 of 3 subgroups of women of reproductive age., Conclusions: . Evidence of the effectiveness of flour fortification for reducing the prevalence of anemia is limited; however, evidence of effectiveness for reducing the prevalence of low ferritin in women is more consistent., (Published by Oxford University Press on behalf of the International Life Sciences Institute 2015. This work is written by US Government employees and is in the public domain in the US.)

The effectiveness of flour fortification in reducing anaemia prevalence is equivocal. The goal was to utilise the existing national-level data to assess whether anaemia in non-pregnant women was reduced after countries began fortifying wheat flour, alone or in combination with maize flour, with at least Fe, folic acid, vitamin A or vitamin B12. Nationally representative anaemia data were identified through Demographic and Health Survey reports, the WHO Vitamin and Mineral Nutrition Information System database and other national-level nutrition surveys. Countries with at least two anaemia surveys were considered for inclusion. Within countries, surveys were excluded if altitude was not consistently adjusted for, or if the blood-draw site (e.g. capillary or venous) or Hb quantification method (e.g. HemoCue or Cyanmethaemoglobin) differed. Anaemia prevalence was modelled for countries that had pre- and post-fortification data (n 12) and for countries that never fortified flour (n 20) using logistic regression models that controlled for time effects, human development index (HDI) and endemic malaria. After adjusting for HDI and malaria, each year of fortification was associated with a 2.4% reduction in the odds of anaemia prevalence (PR 0.976, 95% CI 0.975, 0.978). Among countries that never fortified, no reduction in the odds of anaemia prevalence over time was observed (PR 0.999, 95% CI 0.997, 1.002). Among both fortification and non-fortification countries, HDI and malaria were significantly associated with anaemia (P,0.001). Although this type of evidence precludes a definitive conclusion, results suggest that after controlling for time effects, HDI and endemic malaria, anaemia prevalence has decreased significantly in countries that fortify flour with micronutrients, while remaining unchanged in countries that do not.

Background: Overweight and underweight increase the risk of metabolic impairments and chronic disease. Interventions at the household level require the diagnosis of nutritional status among family members. The aim of this study was to describe the prevalence and patterns of various anthropometric typologies over a decade in Colombia using a novel approach that considers all children in the household as well as the mother. This approach also allows identifying a dual burden of malnutrition within a household, where one child may be overweight and another one undernourished., Methods: This study used data from the Demographic and Health Survey and the Colombian National Nutrition Survey [2000 n = 2,876, 2005 n = 8,598, and 2010 n = 11,349]. Four mutually exclusive household (HH) anthropometric typologies - normal, undernourished, overweight/obese, and dual burden - were created. Anthropometric information of height-for-age Z-scores (HAZ) and body-mass-index-for-age Z-scores (BMIz) in children under the age of 5 y, and on body mass index (BMI) in mothers, 18-49 y was used., Results: Prevalence of overweight/obese HHs increased between 2000 (38.2%) and 2010 (43.1%) (p < 0.05), while undernourished and dual burden HHs significantly decreased between 2005 (13.7% and 10.6%, respectively) and 2010 (3.5% and 5.1%, respectively) (p < 0.05). A greater increase of overweight/obesity was observed for the lowest quintile of wealth index (WI), with an increase of almost 10% between 2000 and 2010, compared to 2% and 4% for the fourth and highest WI, respectively. Although in 2010 there is still a higher prevalence of overweight/obesity HHs in urban areas (43.7%), the prevalence of overweight/obesity HHs in rural areas increased sharply between 2000 (34.3%) and 2010 (41.6%) (p < 0.05)., Conclusion: The observed prevalence of dual burden households was not different from the expected prevalence. Results from this study indicate that although overweight/obesity continues to be more prevalent among high-income Colombian households, it is growing at a faster pace among the most economically disadvantaged.

Objective: To summarize anaemia prevalence data for children, women, and men using data from the second, third and fourth waves of the Indonesia Family Life Surveys (IFLS), which were conducted in 1997/8, 2000, and 2007/8, respectively., Methods: Anaemia prevalence was determined for children 0 to 5 years, 5 to 12 years, 12 to 15 years, non-pregnant women at least 15 years, pregnant women at least 15 years, and men at least 15 years, based on haemoglobin adjusted for altitude and smoking status., Results: Compared with 1997/8 estimates, anaemia prevalence estimates were lower in 2007/8 for all groups, with the greatest relative decline occurring in children 5 to 12 years (25.4%). Trend analysis found anaemia significantly declined over the survey years for all groups (χ² p=0.005 for pregnant women, χ² p<0.001 for all other groups)., Conclusions: IFLS anaemia estimates for different population groups decreased between 1997/8 and 2007/8 and were consistent with estimates from Southeast Asia, and with other studies conducted in Indonesia. While the prevalence of anaemia consistently decreased in all groups, anaemia remains a moderate public health problem for children 0 to 5 years, children 5 to 12 years, and non-pregnant and pregnant women.

Objective: To determine and describe the prevalence and patterns of three recommended practices for infant and young child feeding-exclusive breastfeeding (EB), continued breastfeeding (CB), and achievement of minimum dietary diversity-in four regions in Haiti, and to identify the attitudes and beliefs that inform these practices and any other factors that may facilitate or impede their implementation., Methods: This study utilized a mixed-methods approach consisting of 1) a cross-sectional survey (n = 310) and 2) 12 focus group discussions among women ≥18 years old with children ≤ 2 years old. Multivariable logistic regression analyses were conducted to identify factors associated with 1) EB during the first six months of life, 2) CB for children ≥ 2 years old, and 3) receipt of a diverse variety of complementary foods. Qualitative data were recorded, transcribed verbatim, and analyzed for common themes. Data were collected in June and July 2013 in four departments in Haiti: Artibonite, Nippes, Ouest, and Sud-Est., Results: Prevalence of EB, CB, and achievement of minimum dietary diversity was 57.0%, 11.9%, and 21.2% respectively. EB was statistically significantly associated with infant's age when controlling for annual household income, location of most recent birth, or receipt of CB counseling (odds ratio (OR) = 0.67 (95% CI: 0.47-0.97)). CB was not statistically significantly associated with rural place of residence, receipt of CB counseling, parity, or infant's age. Meeting minimum dietary diversity was not significantly associated with parity, receipt of postnatal care, rural place of residence, location of most recent birth, receipt of infant and young child feeding counseling, or level of schooling. Beliefs surrounding the relationship between the mother's health and her diet on the quality of breast milk may prohibit EB and CB. Qualitative data revealed that dietary diversity may be low because 1) mothers often struggle to introduce complementary foods and 2) those that are traditionally introduced are not varied and primarily consist of grains and starches., Conclusions: Prevalence of the three recommended infant and young child feeding practices examined in this study is suboptimal, particularly CB and achievement of minimum dietary diversity. Future communication and programming efforts should address the misunderstandings and concerns identified through the qualitative methods used in this research.

Fortification is the purposeful addition of vitamins and minerals to foods during their industrial processing, as a way to improve the nutrition and health of populations who consume these foods. Twelve countries have mandatory maize (Zea mays subsp. Mays) flour or meal fortification. The World Health Organization (WHO) is updating evidence-informed guidelines for the fortification of staple foods in public health, including the fortification of maize flour and corn meal with iron and other micronutrients. Although there is limited experience with fortification of maize, mass fortification of maize flour with at least iron has been practiced for many years in several countries in the Americas and Africa: Brazil, Costa Rica, El Salvador, Kenya, Mexico, Nigeria, Rwanda, South Africa, Tanzania, Uganda, the United States, and Venezuela. The WHO, in collaboration with the Sackler Institute for Nutrition Science and the Flour Fortification Initiative (FFI), convened a consultation on technical considerations for fortification of maize flour and corn meal in public health in New York, New York on April 8-9, 2013 to provide input into the guideline-development process and to discuss technical considerations of the fortification processes for maize flour and corn meal., (© 2014 New York Academy of Sciences.

Suboptimal complementary feeding practices contribute to a rapid increase in the prevalence of stunting in young children from age 6 months. The design of effective programmes to improve infant and young child feeding requires a sound understanding of the local situation and a systematic process for prioritizing interventions, integrating them into existing delivery platforms and monitoring their implementation and impact. The identification of adequate food-based feeding recommendations that respect locally available foods and address gaps in nutrient availability is particularly challenging. We describe two tools that are now available to strengthen infant and young child-feeding programming at national and subnational levels. ProPAN is a set of research tools that guide users through a step-by-step process for identifying problems related to young child nutrition; defining the context in which these problems occur; formulating, testing, and selecting behaviour-change recommendations and nutritional recipes; developing the interventions to promote them; and designing a monitoring and evaluation system to measure progress towards intervention goals. Optifood is a computer-based platform based on linear programming analysis to develop nutrient-adequate feeding recommendations at lowest cost, based on locally available foods with the addition of fortified products or supplements when needed, or best recommendations when the latter are not available. The tools complement each other and a case study from Peru illustrates how they have been used. The readiness of both instruments will enable partners to invest in capacity development for their use in countries and strengthen programmes to address infant and young child feeding and prevent malnutrition., (© 2013 John Wiley & Sons Ltd.)

Overweight and micronutrient deficiencies have manifested in the same individuals. This study investigated the association among iron deficiency (ID), anemia, and weight status among nonpregnant Colombian females aged 13-49 y (n = 3267). Data from the 2005 National Survey of the Nutrition Situation were used. The prevalence of ID (plasma ferritin <12.0 μg/L; individuals with CRP >0.012 g/L excluded) and anemia (altitude-adjusted hemoglobin <120 g/L) was estimated separately. The likelihood of having ID or anemia was tested as a function of overweight (BMI-age Z-score 1-1.9 SD for 13-17 y, BMI 25.0-29.9 kg/m² for 18-49 y) and obesity (≥2 SD for 13-17 y, ≥30 kg/m² for 18-49 y) using multivariate logistic regressions accounting for survey design. Additionally, demographic predictors of combined overweight/obesity with ID or anemia were identified. The prevalence of overweight and obesity was 29.2 and 13.1%, respectively, whereas that of ID and anemia was 16.1 and 32.5%, respectively. Contrary to previous reports, overweight and obese women had a lower likelihood of anemia [OR (95% CI) = 0.8 (0.7, 0.9) and 0.8 (0.6, 1.0), respectively] than normal-weight women. Overweight/obesity combined with ID or anemia was present among 6.3 and 12.8% of women, respectively. Although overweight and obesity were associated with a lower likelihood of anemia, a sizeable group of women was identified as experiencing both over- and undernutrition. Because of the potential for exacerbated health problems in the presence of over- and undernutrition, these conditions should continue to be monitored.

Food security is sufficient access to safe and nutritious foods to satisfy nutritional needs and personal preferences, and to lead a healthy and active life. The current study evaluated food security in 302 families with school-age children living in a rural municipality in Cauca, Colombia, and factors associated with food security. Families were participating in an evaluation of the nutrition impact of an intervention with nutritionally improved maize. A12-item food security scale was applied to the household head, as well as a sociodemographic survey. Families were classified as food secure, or mildly, moderately or severely food insecure. Among households, 44.37% were classified as food secure and 55.63% as food insecure (with 41.39% as mildly insecure, 12.25% as moderately insecure and 1,99% as severely insecure). Food-insecure families had fewer persons working relative to the total individuals in the home, 4 or fewer services or assets, and children with a reduced appetite, in comparison with food-secure households. In conclusion, more than half of the sample was food insecure; the factors associated with food insecurity relate to family income.

Early childhood malnutrition has been associated with delayed development. Limited data exist however about the timing of developmental delay early in life. We assessed motor milestone (MM) achievement using the World Health Organization's windows of achievement for gross motor milestones. We performed secondary analysis of baseline data of 158 Vietnamese children aged 5-18 months from a randomized community intervention trial. Median age of motor milestone achievement was compared to WHO reported medians. Multivariate logistic regression was used to identify socioeconomic, anthropometric and dietary factors associated with motor milestone achievement during the windows of achievement. Thirty four per cent of the children were stunted. Median age of MM achievement of Vietnamese children lagged by 2.4-3.7 months, compared to the WHO median for all MMs. Greater length-for-age increased the odds for walking with assistance, standing alone and walking alone by more than 3 times. Greater weight-for-age increased the odds by 3.6 for hand-and-knees crawling. Likewise, frequency of daily complementary feeding raised the odds by 3.6 for standing with assistance. In this first application of WHO windows of achievement in Viet Nam, pre-schoolers achieved motor milestones later than WHO reported median age. High prevalence of stunting and association of length-for-age with motor milestone achievement underscore the importance of addressing chronic malnutrition to optimize children's growth and development.

For social programs in Colombia, like those administered by the Instituto Colombiano de Bienestar Familiar (ICBF), it's important to know what native foods minority groups consume. This research obtained information on native foods consumed by indigenous and afro-descendents living in 10 Colombian departments: Cauca, Nariño, Amazonas, Chocó, Guainia, Vichada, Magdalena, Guajira, Cesar y Vaupés. A questionnaire was applied to key informants (individually or in groups), addressing the following topics: personal information on the informant, name and type of food, if consumed by indigenous and/or afro-Colombians, climate where produced, time of year when harvested, if consumed raw or cooked, preparations, properties ascribed to the food, and current production, use and availability. Key informants included participants in ICBF's programs, indigenous authorities, teachers, traditional healers, and others, under the supervision of professionals from ICBF's mobile unit in each department. Bibliography (n = 123 documents) was compiled and reviewed. In the departments selected, 13 municipalities were visited, 139 individuals were interviewed and at least 92 new foods (i.e., not currently included in the Colombian Food Composition Table) were identified. Among the 92, the scientific name was obtained for 62 foods. Of these, 2 were classified as other, 18 as meats, 3 as insects, and 39 as plants. Among the plants, informants mentioned fruit (n=29), leaves (n=4), seed (n=3) and roots (n=3). Indigenous and afro-descendent communities in Colombia report consuming dozens of foods that are not currently in the Colombian Food Composition Table.

Objective: Ten typical recipes from southwestern Colombia were evaluated at CIAT in Palmira, Colombia between 2008 and 2009., Material and Methods: The recipes were prepared in a traditional manner, using quality protein maize (QPM, with more tryptophan and lysine) or common maize (CM); each of these was either fresh kernel or dry grain, or white or yellow maize, per the recipe. The two types of maize were compared for their protein quality., Results: Tryptophan concentrations were 0.011-0.072% and 0.012-0.107% for CM and QPM, respectively. Tryptophan values for QPM recipes were greater than or equal to those for CM recipes. Soluble protein ranged from 2.359-14.783 g/kg for CM and 3.339-16.839 g/kg for QPM. Except for one recipe, soluble protein in QPM recipes was greater or equal to that of CM recipes. In vitro protein digestibility was 75-84% for recipes prepared with both maize types. Only four recipes had a statistically significant difference between QPM and CM with regard to digestibility., Conclusions: Most recipes prepared with QPM had a higher protein quality than those prepared with CM.

Objective: To identify geographical areas in Latin America and the Caribbean where biofortification of staple crops, such as beans, corn, rice, cassava, and sweet potatoes, might help reduce nutritional deficiencies in the Region., Methods: A geographic information system (GIS) was produced with records on nutritional risks, crop production, food consumption, and demographic and socioeconomic data, for 11 countries in the Region. Four case studies were conducted (in Bolivia, Colombia, Guatemala, and Mexico) using exploratory and descriptive analysis of thematic maps that were superimposed and compared to reveal overlapping and spatial patterns, thereby identifying areas suited to intervention., Results: In Guatemala, the highest rates of nutritional risk, bean production, and population density overlapped in the northeast and southeast areas. In Mexico, spatial distribution of the highest risk levels for nutrition, poverty, and corn production were concentrated in the central and southern municipalities. In Bolivia, bean production tended to be in the eastern part of the country, and nutritional risk, in the west. In Colombia, both nutritional risk and cassava production showed wide geographic dispersion., Conclusions: For Guatemala, we propose iron biofortification of beans in the southern parts of the northeast and southeast; for Mexico, amino-acid biofortification of corn in the central and southern municipalities that produce it; for Bolivia, iron and zinc biofortification of beans in the bean-producing areas of Santa Cruz, Chuquisaca, and Tarija; and for Colombia, beta-carotene biofortification of cassava in the Cordoba and Cundinamarca departments.

Haiti is the poorest country in the Western Hemisphere and is heavily affected by food insecurity and malaria. To find out if these 2 conditions are associated with each other, we studied a convenience sample of 153 women with children 1-5 y old in Camp Perrin, South Haiti. Household food insecurity was assessed with the 16-item Escala Latinoamericana y Caribeña de Seguridad Alimentaria (ELCSA) scale previously validated in the target communities. ELCSA's reference time period was the 3 mo preceding the survey and it was answered by the mother. Households were categorized as either food secure (2%; ELCSA score = 0), food insecure/very food insecure (42.7%; ELCSA score range: 1-10), or severely food insecure (57.3%; ELCSA score range: 11-16). A total of 34.0% of women reported that their children had malaria during the 2 mo preceding the survey. Multivariate analyses showed that severe food insecure was a risk factor for perceived clinical malaria (odds ratio: 5.97; 95% CI: 2.06-17.28). Additional risk factors for perceived clinical malaria were as follows: not receiving colostrum, poor child health (via maternal self-report), a child BMI <17 kg/m(2), and child vitamin A supplementation more than once since birth. Findings suggest that policies and programs that address food insecurity are also likely to reduce the risk of malaria in Haiti.

Background: Agricultural science can address a population's vitamin, amino acid and mineral malnutrition through biofortification - agronomy, plant breeding and biotechnology to develop crops with high nutrient contents. Biofortified crop varieties should be grown in areas with populations at risk of nutrient deficiency and in areas where the same crop is already grown and consumed. Information on the population at risk of nutrient deficiency is rarely available for sub-national administrative units, such as provinces, districts, and municipalities. Nor is this type of information commonly analyzed with data on agricultural production. This project developed a method to identify populations at risk of nutrient deficiency in zones with high crop production, places where biofortification interventions could be targeted., Results: Nutrient deficiency risk data were combined with crop production and socioeconomic data to assess the suitability of establishing an intervention. Our analysis developed maps of candidate sites for biofortification interventions for nine countries in Latin America and the Caribbean. Results for Colombia, Nicaragua, and Bolivia are presented in this paper. Interventions in northern Colombia appear promising for all crops, while sites for bean biofortification are widely scattered throughout the country. The most promising sites in Nicaragua are found in the center-north region. Candidate sites for biofortification in Bolivia are found in the central part of the country, in the Andes Mountains. The availability and resolution of data limits the analysis. Some areas show opportunities for biofortification of several crops, taking advantage of their spatial coincidence. Results from this analysis should be confirmed by experts or through field visits., Conclusion: This study demonstrates a method for identifying candidate sites for biofortification interventions. The method evaluates populations at risk of nutrient deficiencies for sub-national administrative regions, and provides a reasonable alternative to more costly, information-intensive approaches.
