A Comparative Analysis of Maternal Nutrition Decision-Making Autonomy During Pregnancy-An Application of the Food Choice Process Model in Burkina Faso and Madagascar

BACKGROUND

Adequate nutrition has been cited as one of the most critical components for optimal health outcomes during pregnancy. Women in Burkina Faso and Madagascar experience high rates of undernutrition due to lack of knowledge, finances, cultural norms, and autonomy. Therefore, this study aimed (1) to describe typical maternal diets during pregnancy in Burkina Faso and Madagascar, (2) to understand the multilevel factors that influence women's nutrition decision-making, and (3) to explore the extent to which women have nutrition decision-making autonomy during pregnancy.

METHODS

This study was conducted between October 2020 and February 2021 in Burkina Faso and Madagascar. Semi-structured interviews, focus group interviews, and free lists were conducted among women of reproductive age and pregnant and lactating women. Textual data from interviews were recorded and translated verbatim from local languages into French. The Food Choice Process Model guided textual content analysis using Dedoose software. Free list data were analyzed using cultural domain analysis approaches.

RESULTS

In Burkina Faso and Madagascar, women primarily consumed staple foods such as rice and tô during pregnancy. Participants cited eating fruits and vegetables when available, while the animal source foods were rarely consumed. Across both contexts, nutrition during pregnancy was influenced by factors that impact food choices, such as social factors, resources, ideals, and personal factors. While women and men in Madagascar had more shared decision-making on critical domains such as finances, men were the primary decision-makers in most areas of inquiry (eg, finances) in Burkina Faso.

CONCLUSIONS

The lack of adequate diverse diet consumed during pregnancy is primarily due to important factors including social factors and resources. Understanding the ability for women to consume optimal diets during pregnancy is needed to target behavioral change in maternal nutrition programming.

Precision Nutrition Opportunities to Help Mitigate Nutrition and Health Challenges in Low- and Middle-Income Countries: An Expert Opinion Survey

Precision nutrition involves several data collection methods and tools that aim to better inform nutritional recommendations and improve dietary intake, nutritional status, and health outcomes. While the benefits of collecting precise data and designing well-informed interventions are vast, it is presently unclear whether precision nutrition is a relevant approach for tackling nutrition challenges facing populations in low- and middle-income countries (LMIC), considering infrastructure, affordability, and accessibility of approaches. The Swiss Food & Nutrition Valley (SFNV) Precision Nutrition for LMIC project working group assessed the relevance of precision nutrition for LMIC by first conducting an expert opinion survey and then hosting a workshop with nutrition leaders who live or work in LMIC. The experts were interviewed to discuss four topics: nutritional problems, current solutions, precision nutrition, and collaboration. Furthermore, the SFNV Precision Nutrition for LMIC Virtual Workshop gathered a wider group of nutrition leaders to further discuss precision nutrition relevance and opportunities. Our study revealed that precision public health nutrition, which has a clear focus on the stratification of at-risk groups, may offer relevant support for nutrition and health issues in LMIC. However, funding, affordability, resources, awareness, training, suitable tools, and safety are essential prerequisites for implementation and to equitably address nutrition challenges in low-resource communities.

Knowledge, Attitudes and Practices of Pregnant Women and Healthcare Providers in Bangladesh regarding Multivitamin Supplements during Pregnancy

Micronutrient deficiencies are widespread among pregnant women in low- and middle-income countries (LMIC) and lead to potentially adverse effects for mother and baby. In Bangladesh, maternal malnutrition remains a severe problem, with high rates of anemia (49.6% of pregnant women and 47.8% of lactating women are anemic) and other nutritional deficiencies. A Knowledge, Attitudes, and Practices (KAP) study was conducted to assess Bangladeshi pregnant women's perceptions and related behaviors, as well as awareness and knowledge among pharmacists and healthcare professionals concerning prenatal multivitamin supplements. This was done in both rural and urban areas across Bangladesh. A total of 732 quantitative interviews were conducted (330 with providers and 402 with pregnant women, with an equal split between urban and rural areas for both sets of audiences; 200 women were users of prenatal multivitamin supplements, while 202 women were aware non-users). The study identified a few findings that can guide further research or market-based interventions to reduce micronutrient deficiencies. These include most pregnant women not knowing the right time to start multivitamin supplements (56.0%, [n = 225], stating that a woman should start taking supplements 'after the first trimester'), not knowing their benefits, and how they help both the mother and baby-only 29.5% [n = 59] stated that they believed the supplements helped their baby to grow well). Further, barriers to taking the supplements include women believing a nutritious diet is a substitute (88.7% [n = 293]), and a perceived lack of support from other family members (21.8%, [n = 72]). This suggests that there is a need for further awareness-raising among all pregnant women, their family members, and providers.

Nutrition in City Ecosystems (NICE): Protocol of a multi-sectoral development project to improve food and nutrition security of secondary city populations in Bangladesh, Kenya and Rwanda

Background

Secondary cities tend to be better linked with local food systems than primate cities, acting as important platforms to trade agricultural produce with rural surrounding. COVID-19, conflicts and climate change continue to expose inefficiencies in food systems and have further exacerbated malnutrition, calling for substantial food systems transformations. However, tackling current food systems' challenges requires new approaches to ensure food and nutrition security. Nutritious and agroecologically produced food offer the potential to transform food systems by improving diets and alleviating pressure on the environment, as well as by creating jobs and reducing poverty. This paper describes the design of a project by a Swiss public-private consortium to improve food and nutrition security and to reduce poverty in city ecosystems in six secondary cities in Bangladesh, Kenya and Rwanda through governance/policy and supply and demand side interventions.

Methods

The Nutrition in City Ecosystems (NICE) project promotes well-balanced nutrition for city populations through interdisciplinary agricultural, food, and health sector collaborations along city-specific value chains. Adopting a transdiciplinary systems approach, the main interventions of NICE are (i) advocacy and policy dialogue, (ii) building of decentralized institutional capacity in multi-sectoral collaborations, (iii) support of data-driven planning, coordination and resource mobilization, (iv) anchoring of innovations and new approaches in city-level partnerships, (v) capacity building in the agricultural, retail, health and education sectors, as well as (vi) evidence generation from putting policies into practice at the local level. NICE is coordinated by in-country partners and local offices of the Swiss public-private consortium partners.

Discussion

The NICE project seeks to contribute to urban food system resilience and enhanced sustainable nutrition for city populations by (A) strengthening urban governance structures involving key stakeholders including women and youth, (B) generating income for producers along the supply chain, (C) triggering change in producers' and consumers' behavior such that nutritious and agroecologically produced foods are both in demand as well as available and affordable in urban markets, and (D) allowing a scale up of successful approaches to other national and international cities and city networks.

Nutrition as a driver and outcome of agroecology

The principles of agroecology do not explicitly state a link with nutrition. Yet, we argue that among them, input reduction, biodiversity, economic diversification, social values and diets, fairness, connectivity and participation are directly linked to nutrition. Nutrition can serve as a critical outcome and driver of agroecological practices and can drive transformative change across the food system.

Small and Medium Enterprises' Perspectives on Food Fortification Amid the Growing Burden of Malnutrition

The need for a profound food system transformation has never been greater. The growing burden of malnutrition has become the new normal, with two billion people who are overweight, over 140 million children under five who are stunted and over two billion people affected by hidden hunger. Food fortification has been recognized as a cost-effective strategy to address micronutrient deficiencies. Small and medium enterprises (SMEs) play a strategic role in the food supply chain in low- and middle-income countries, accounting for over 80% of food sales. It is therefore critical to create an enabling environment to facilitate SMEs' involvement in food fortification practices as a potential solution to tackle all forms of malnutrition. This review highlights SMEs' relevance as agents of change in the food system through food fortification practices and their indirect yet key role in producing nutritious, tasty and affordable foods. It discusses their challenges (e.g., access to long-term finance, sustainable technical assistance, limited capacity), presents solutions and discusses how different actors can help SMEs to overcome these challenges. Furthermore, it presents a relevant public-private partnership case study to demonstrate how SMEs can address the growing burden of malnutrition through food fortification practices, nutrient profiling schemes and demand generation.

Evaluation of spray-dried eggs as a micronutrient-rich nutritional supplement

Regular consumption of hen eggs can help to prevent deficiencies of essential nutrients, such as essential amino acids, vitamin A and E or trace elements zinc and selenium, for vulnerable populations. This study focused on assessing the nutritional value of spray-dried eggs, favored by their manufacturability, storability and ease of addition to (complementary) foods. Using a wide range of analytical techniques, we recorded and compared the nutrient profiles of commercially produced pasteurized whole eggs and their respective powder samples spray-dried at 160°C. Important nutrients that were not significantly affected by spray-drying include total fat content, several amino acids, α- and δ-tocopherol, lutein, zeaxanthin, essential trace elements and cobalamin. The most notable mean losses were found for unsaturated fatty acids, e.g., linoleic (by −38.7%, from 4.11 ± 0.45 to 2.52 ± 0.75 g/100 g DM) and linolenic acid (by −60.8%, from 0.76 ± 0.05 to 0.30 ± 0.04 g/100 g DM). Despite recording significant retinol losses in two out of three batches, the overall low reduction of −14% recommend spray-dried eggs as a valuable source of vitamin A. A daily intake of spray-dried egg powder corresponding to one medium sized egg meets dietary reference values for children, e.g., by 100% for vitamin E, by 24% for retinol, by 61% for selenium and by 22% for zinc. In conclusion, even though a dry weight comparison favors supplementation with pasteurized whole eggs, our results demonstrate a high potential for spray-dried eggs as nutritional supplement. However, the spray-drying process should be optimized toward higher retentions of unsaturated fatty acids and retinol.

Formative Research to Tailor Maternal Nutrition Services Introducing Multiple Micronutrient Supplements (MMS) for Pregnant Women in Rural Madagascar

Objectives

To develop tailored social marketing approaches for introducing multiple micronutrient supplements (MMS) to pregnant women in rural Madagascar.

Methods

Design. This formative study utilized a Rapid Assessment Procedures approach conducted over two iterative phases in Itasy and Vatovavy Fitovinany, Madagascar from October 2020 – March 2021. Data collection and sampling.Phase 1 utilized community workshops, focus groups, and market observations to generate community inputs for developing culturally appropriate and tailored MMS programming. Phase 2 included free lists and semi-structured interviews among pregnant women and health workers for an ethnographic understanding of pregnancy-related practices in this setting. Analysis. Textual data from interviews were thematically analyzed using Dedoose software. Numerical data from market observations and community workshops were summarized using descriptive statistics. Findings were grounded in a social marketing framework and triangulated across methods and participant types to enhance data credibility.

Results

Formative findings can be conceptualized using the ‘4ps’ of social marketing: Product. In this setting, women voted for an orange-colored MMS box design because the color reflects locally-available fruits such as mangoes and oranges. Red and white colors were secondary preferences. Price. Pregnant women explained some willingness to pay for MMS, suggesting that 500 to 600 Ar/30-day supply may be appropriate, but emphasizing the need for free provision to increase coverage among more vulnerable groups. Placement. Distributing MMS using a combination of both facility-based and community-based approaches was suggested by participants for ensuring optimal program coverage and reach. Promotion. Pregnant women suggested the need for community-based, interpersonal communications using health agents and health workers as the primary communication channels to promote MMS compliance. Several local language (Malagasy) phrases were generated through participatory workshops to promote MMS specifically to pregnant women in this setting.

Conclusions

Participatory formative research in rural Madagascar provided context-specific, social marketing inputs that may help improve MMS acceptability and compliance in Madagascar.

A Comparative Analysis of Maternal Nutrition Decision-Making Autonomy During Pregnancy in Burkina Faso and Madagascar – An Application of the Food Choice Process Model

Objectives

The study aimed to conceptualize maternal nutrition decisions in rural Burkina Faso and Madagascar using the Food Choice Process Model by 1) describing typical maternal diets during pregnancy, 2) understanding multi-level factors that influence women's dietary choices, and 3) exploring the extent to which pregnant women have nutrition decision-making autonomy.

Methods

This multi-phased, formative study was conducted between Oct. 2020 - Feb. 2021 in Burkina Faso and Madagascar. Data collection methods and sampling. Semi structured interviews (n = 46), focus group interviews (n = 12), and free lists (n = 90) were conducted among pregnant and lactating women. Analysis. Textual data from focus groups and semi-structured interviews were recorded and translated verbatim from local languages into French. The Food Choice Process Model guided textual content analysis using Dedoose software. Free list data were analyzed using cultural domain analysis approaches.

Results

Pregnant women receive nutrients through diets consisting primarily of staple foods, including rice and tô (millet or maize-based dough) in Madagascar and Burkina Faso, respectively. While locally-available vegetables and fruits are sometimes consumed when available, animal-source foods are rarely eaten among these samples. Differentially between contexts, maternal nutrition is influenced by a synergy of upstream factors that impact individual food choices, including available resources, social influences, and personal characteristics and ideals. While shared decision-making within key domains of autonomy (e.g., household finances) is normative between men and women in Madagascar, men were the primary decision makers across all areas of inquiry among the sample of participants from Burkina Faso.

Conclusions

Sub-optimal maternal diets are determined by inter-related, multi-level factors in Burkina Faso and Madagascar. Further exploration on decision-making autonomy and its role in women's ability to consume optimal diets during pregnancy in these settings should be considered.

Principles for Evidence-Based and Sustainable Food System Innovations for Healthier Diets

Climate change, rapid urbanization, war, and economic recession are key drivers of the current food systems’ disruption, which has been exacerbated by the COVID pandemic. Local, regional, and global food systems are unable to provide consumers with nutritious and affordable diets. Suboptimal diets exacerbate the triple burden of malnutrition, with micronutrient deficiencies affecting more than two billion people, two billion people suffering from overweight, and more than 140 million children who are stunted. The unaffordability of nutritious diets represents an obstacle for many, especially in low- and middle-income countries where healthy diets are five times more expensive than starchy staple diets. Food system transformations are urgently required to provide consumers with more affordable and nutritious diets that are capable of meeting social and environmental challenges. In this review, we underline the critical role of innovation within the food system transformation discourse. We aim to define principles for implementing evidence-based and long-term food system innovations that are economically, socially, and environmentally sustainable and, above all, aimed at improving diets and public health. We begin by defining and describing the role of innovation in the transformation of food systems and uncover the major barriers to implementing these innovations. Lastly, we explore case studies that demonstrate successful innovations for healthier diets.

Effect of multiple micronutrient supplements vs iron and folic acid supplements on neonatal mortality: a reanalysis by iron dose

OBJECTIVE

Antenatal multiple micronutrient supplements (MMS) are a cost-effective intervention to reduce adverse pregnancy and birth outcomes. However, the current WHO recommendation on the use of antenatal MMS is conditional, partly due to concerns about the effect on neonatal mortality in a subgroup of studies comparing MMS with iron and folic acid supplements (IFA) containing 60 mg of iron. We aimed to assess the effect of MMS vs IFA on neonatal mortality stratified by iron dose in each supplement.

METHODS

We updated the neonatal mortality analysis of the 2020 WHO guidelines using the generic inverse variance method and applied the random effects model to calculate the effect estimates of MMS vs. IFA on neonatal mortality in subgroups of trials (n=13) providing the same or different amounts of iron, i.e. MMS with 60 mg of iron vs IFA with 60 mg of iron; MMS with 30 mg of iron vs IFA with 30 mg of iron; MMS with 30 mg of iron vs IFA with 60 mg of iron; and MMS with 20 mg of iron vs IFA with 60 mg of iron.

RESULTS

There were no statistically significant differences in neonatal mortality between MMS and IFA within any of the subgroups of trials. Analysis of MMS with 30 mg vs IFA with 60 mg of iron (7 trials, 14,114 participants), yielded a nonsignificant Risk Ratio (RR) of 1.12 (95% CI 0.83 to 1.50).

CONCLUSION

Neonatal mortality did not differ between MMS and IFA regardless of iron dose in either supplement.

Multiple micronutrient supplements versus iron-folic acid supplements and maternal anemia outcomes: an iron dose analysis

Antenatal multiple micronutrient supplements (MMS) are more effective than iron and folic acid (IFA) supplements in reducing adverse pregnancy outcomes. Questions remain, however, about the ability of MMS to prevent anemia as effectively as IFA, especially at a lower dose of daily iron and in areas of high anemia prevalence. Analyzing data from 11 trials from a recent Cochrane review, we compared MMS to IFA, delivering either 30 or 60 mg of iron, in sustaining hemoglobin and preventing third trimester anemia and iron deficiency anemia (IDA), accounting for daily iron dose, total supplemental iron intake, and baseline prevalence of anemia. There were no differences between MMS and IFA in third trimester hemoglobin concentration or risks of anemia or IDA by iron dose or total supplemental iron consumed. MMS providing 30 mg of iron was comparable to IFA with 60 mg of iron: mean hemoglobin difference of −0.26 g/L (95% CI: −1.41 to 0.89), risk ratios of 0.99 (95% CI: 0.92–1.07) for anemia, and 1.31 (95% CI: 0.66–2.60) for IDA. Baseline prevalence of anemia did not explain heterogeneity in findings. Compared to IFA, MMS results in comparable hemoglobin concentration and protection against anemia during pregnancy, independently of iron dose.

Interventions to improve calcium intake through foods in populations with low intake

Calcium intake remains inadequate in many low- and middle-income countries, especially in Africa and South Asia, where average intakes can be below 400 mg/day. Given the vital role of calcium in bone health, metabolism, and cell signaling, countries with low calcium intake may want to consider food-based approaches to improve calcium consumption and bioavailability within their population. This is especially true for those with low calcium intake who would benefit the most, including pregnant women (by reducing the risk of preeclampsia) and children (by reducing calcium-deficiency rickets). Specifically, some animal-source foods that are naturally high in bioavailable calcium and plant foods that can contribute to calcium intake could be promoted either through policies or educational materials. Some food processing techniques can improve the calcium content in food or increase calcium bioavailability. Staple-food fortification with calcium can also be a cost-effective method to increase intake with minimal behavior change required. Lastly, biofortification is currently being investigated to improve calcium content, either through genetic screening and breeding of high-calcium varieties or through the application of calcium-rich fertilizers. These mechanisms can be used alone or in combination based on the local context to improve calcium intake within a population.

The Future of Moringa Foods: A Food Chemistry Perspective

The tree Moringa oleifera Lam. provides its leaves, pods, flowers and seeds for human nutrition. The chemical profile of all these Moringa products varies substantially, not only among the different parts of the plants used. Cultivating, processing as well as storage conditions chiefly determine the contents of nutrients and anti-nutritive constituents. Anti-nutrients, e.g., phytic acid or tannins, are present in notable amounts and may affect micronutrient bioavailability. Although Moringa oleifera products have been promoted for several health benefits and are discussed as an alternative treatment in various diseases, risk assessment studies evaluating contamination levels are scarce. Recent investigations have demonstrated alarming contents of heavy metals, polycyclic aromatic hydrocarbons and mycotoxins in Moringa oleifera products, indicating the need for a comprehensive risk assessment and contingent legal regulation of these products. In this mini review, we briefly outline pivotal, food chemistry and nutrition related data on Moringa preparations in order to stimulate in-depth research to close the presented knowledge gaps.

Nutrient Density as a Dimension of Dietary Quality: Findings of the Nutrient Density Approach in a Multi-Center Evaluation

The nutrient adequacy of a diet is typically assessed by comparing estimated nutrient intakes with established average nutrient requirements; this approach does not consider total energy consumed. In this multinational survey investigation in Indonesia, Mexico, and South Africa, we explore the applications of the “critical nutrient-density approach”—which brings energy requirements into the equation—in the context of public health epidemiology. We conducted 24 h dietary recalls in convenience samples of normal-weight (BMI 18.5–25 kg/m²) or obese (BMI > 30 kg/m²), low-income women in three settings (n = 290). Dietary adequacy was assessed both in absolute terms and using the nutrient density approach. No significant differences in energy and nutrient intakes were observed between normal-weight and obese women within any of the three samples (p > 0.05). Both the cut-point method (% of EAR) and critical nutrient density approach revealed a high probability of inadequate intakes for several micronutrients but with poor concordance between the two methods. We conclude that it may often require some approximate estimate of the habitual energy intake from an empirical source to apply a true critical nutrient density reference for a population or subgroup. This will logically signify that there would be more “problem nutrients” in the diets examined with this nutrient density approach, and efforts toward improved food selection or food- or biofortification will frequently be indicated.

The Potential Impact of Climate Change on the Micronutrient-Rich Food Supply

Micronutrient deficiencies are a major cause of morbidity and mortality in low- and middle-income countries worldwide. Climate change, characterized by increasing global surface temperatures and alterations in rainfall, has the capacity to affect the quality and accessibility of micronutrient-rich foods. The goals of this review are to summarize the potential effects of climate change and its consequences on agricultural yield and micronutrient quality, primarily zinc, iron, and vitamin A, of plant foods and upon the availability of animal foods, to discuss the implications for micronutrient deficiencies in the future, and to present possible mitigation and adaptive strategies. In general, the combination of increasing atmospheric carbon dioxide and rising temperature is predicted to reduce the overall yield of major staple crops, fruits, vegetables, and nuts, more than altering their micronutrient content. Crop yield is also reduced by elevated ground-level ozone and increased extreme weather events. Pollinator loss is expected to reduce the yield of many pollinator-dependent crops such as fruits, vegetables, and nuts. Sea-level rise resulting from melting of ice sheets and glaciers is predicted to result in coastal inundation, salt intrusion, and loss of coral reefs and mangrove forests, with an adverse impact upon coastal rice production and coastal fisheries. Global ocean fisheries catch is predicted to decline because of ocean warming and declining oxygen. Freshwater warming is also expected to alter ecosystems and reduce inland fisheries catch. In addition to limiting greenhouse gas production, adaptive strategies include postharvest fortification of foods; micronutrient supplementation; biofortification of staple crops with zinc and iron; plant breeding or genetic approaches to increase zinc, iron, and provitamin A carotenoid content of plant foods; and developing staple crops that are tolerant of abiotic stressors such as elevated carbon dioxide, elevated temperature, and increased soil salinity.

Knowledge Gaps in Understanding the Etiology of Anemia in Indonesian Adolescents

BACKGROUND

Anemia is a public health problem among adolescents in Indonesia. Strategies to prevent or treat anemia should be tailored to local conditions, taking into account its specific etiology and prevalence in a given setting and population group.

OBJECTIVE

This review aims to (1) identify and synthesize the current knowledge on the etiology of anemia among adolescents in Indonesia, (2) reveal knowledge gaps in this area, and (3) suggest directions for future research and programmatic work.

METHODS

We systematically searched PubMed, Web of Science, Scopus, Medline, and WorldCat databases for peer-reviewed journal articles to identify which etiological factors were related to anemia among Indonesian adolescents. Research papers were reviewed and included in the review according to inclusion criteria.

RESULTS

Of 13 studies, 8 showed that anemia was associated with iron deficiency; 4 are suggestive of vitamin A deficiency; and 2 of folic acid deficiency. Five studies underscore different etiological determinants for anemia, such as malaria, protein and energy malnutrition, vitamin B2 deficiency, calcium, and vitamin C deficiency. Based on these findings, we developed a framework on knowledge gaps on the etiology of anemia among adolescents in Indonesia, divided in 3 levels of knowledge: (1) significant knowledge gaps, (2) knowledge gaps, and (3) established knowledge.

CONCLUSIONS

The knowledge gaps around the etiology of anemia among Indonesian adolescents are significant. Our framework emphasizes the need for further research across all etiological factors, namely inadequate nutritional intake and absorption, genetic hemoglobin disorders, infection and inflammation, and menstrual disorders.

The Triple Burden of Malnutrition Among Adolescents in Indonesia

BACKGROUND

Indonesia is a prime example of the triple burden of malnutrition. Indonesian adolescents are among the hardest hit, with approximately one in four adolescent girls suffering from anemia, while nearly one in seven adolescents is overweight or obese.

OBJECTIVES

The present editorial provides a snapshot of the various research papers included in this Supplement, which calls for increased attention to adolescent nutrition in Indonesia and beyond.

RESULTS

Despite major steps to reduce undernutrition and overweight, including a renewed focus on anemia among adolescent girls, major gaps remain in our understanding of various nutrition issues concerning adolescents. These include various drivers and determinants of the triple burden of malnutrition, evidence-based interventions that are supported by large-scale implementation research and evaluation, and effective delivery platforms to reach the most vulnerable groups of adolescents.

CONCLUSION

The time has come to position adolescent nutrition as central to development, and mainstream it into health sector plans, strategies, and policies. It is our hope that this issue will stimulate the urgently needed interventions, implementation research and required programs that will safeguard the nutritional wellbeing of today's forgotten generation.

Chronic Vitamin E Deficiency in Rural Bangladeshi Women

Objectives

Vitamin E deficiency (VED) appears to be common in rural areas of South Asia, with prevalence of ≥ 50% reported among women of reproductive age. Long term deficiency may impart neurological damage, but little information exists about persistence of VED. We provide initial estimates of chronic VED (CVED) in women of reproductive age living in Gaibandha District, a typical rural setting in NW Bangladesh.

Methods

We assessed α-tocopherol concentrations by HPLC in early pregnancy and 3-month postpartum (PP) plasma samples of women participating in biochemical sub-studies of JiVitA-1 (n = 2,319), a cluster-randomized, placebo-controlled, weekly vitamin A or β-carotene supplementation trial from 2001–7, and JiVitA-3 (N = 2,073), a cluster-randomized, daily multiple micronutrient (MMS) versus iron-folic acid (IFA) supplementation trial from 2008–12. VED was conventionally defined by an α-tocopherol concentration < 12 μmol/L and CVED as α-tocopherol < 12 μmol/L at both early pregnancy and postpartum assessments, an interval spanning a median (IQR) of 9.4 (2.8) months.

Results

Across both trials combined (N = 4,392), the mean ± SD plasma α-tocopherol concentration and prevalence of VED in early pregnancy and at 3 months post-partum was 11.28 ± 4.07 and 10.86 ± 4.41 μmol/L, and 53.5% and 42.2%, respectively. In JiVitA-3, the post-partum prevalence of VED among women not previously receiving MMS (containing 15 mg of vitamin E as all-rac-α-tocopheryl acetate) was 57.5% (vs 42.5% among MMS recipients, p < 0.001). The prevalence of CVED among women in both trials combined was 32.0% (34.45% in JiVitA-1 and 26.65% in JiVitA-3, IFA group only). Across a maternal age range of 11–43 [median: 20 (IQR: 8) years, risk of CVED decreased comparably per year of age in the JiVitA-1 [OR = 0.94 (95% CI: 0.93–0.95)] and JiVitA-3 [OR = 0.93 (95% CI:0.92–0.95)] trials.

Conclusions

In rural NW Bangladesh, where over half of women enter pregnancy vitamin E-deficient, about one-third are also deficient postpartum, ∼10 months later, providing a provisional estimate of chronic maternal vitamin E deficiency in a South Asian setting.

Harnessing Participatory Formative Research to Inform Women's Preferences on Multiple Micronutrient Supplement (MMS) Design Considerations Across Four Country Contexts

Objectives

To determine universally acceptable MMS box design inputs including preferred color scheme, logo, and slogan options to include in demonstration projects across four countries.

Methods

Design: This multi-phased, formative study was conducted between Oct. 2020 - Feb. 2021 in Burkina Faso, Bangladesh, Tanzania, and Madagascar. It was designed using a social marketing framework and employed Rapid Assessment Procedures (RAP). Data collection methods and sampling: Qualitative methods were used to inform MMS product design and promotional strategies, including 40 participatory workshops and 32 focus group discussions with pregnant women across four countries. In Burkina Faso, a survey was administered to pregnant women (n = 30) for further triangulation. During data collection, several mock MMS box designs, with design options based on local contexts, were used as stimulus prompts for discussion and voting on preferred MMS design color schemes, logos, and slogans. Analysis: Data across methods were synthesized to identify the most preferred MMS characteristics.

Results

Color scheme: Overall, a white/pink MMS box color scheme was the most preferred, universal packaging color across countries. Participants explained that white was “clean”, and in Burkina Faso, it reminded participants of a local paracetamol package “which has no side effects.” The pink was described as “soft and attractive.” In Madagascar, there was a stronger preference for an orange/green color scheme, with pink as a second choice. Box logo: Across countries, participants suggested an image of a pregnant woman on the box design to ensure it is recognizable for its intended purpose. In Burkina Faso, participants voted for a ‘healthy pregnant woman smiling, holding the supplement’ and in Madagascar, participants preferred a ‘healthy, pregnant woman taking the supplement.’ Promotional slogans: While there was variation in specific slogan recommendations to promote MMS by country, shared themes related to good health, strength, happiness, and God. The MMS box design was thus tailored to reflect a combination of preferences.

Conclusions

Engaging pregnant women who will be end-users of MMS through participatory methods in four countries aided to inform programming that may improve supplement acceptability and compliance across contexts.

Antenatal Multiple Micronutrient Supplementation in the State of Palestine: A Protocol for Implementation and Evaluation

Objectives

The 2013 Palestinian Micronutrient Survey¹ reported high and comparable 1^st trimester prevalences of micronutrient deficiencies in the Gaza Strip and West Bank: 23.6% and 21.3% for iron, 67.9% and 49.6% for zinc, 11.4% and 8.8% for vitamin A, 27.9% and 19.1% for B₁₂, 78.6% and 66.7% for vitamin D and 17.5% and 13.2% for vitamin E, respectively. Rates were generally higher among gravida in their 2^nd-3^rd trimesters. Interim, clinic-based, anemia rates² in the Gaza Strip and West Bank of 32% and 19% in the first trimester and 71% and 38% in the 2^nd and 3^rd trimesters, respectively, coupled with food insecurity, dietary inadequacy, civil conflict and stresses from the COVID-19 pandemic, suggest micronutrient deficiencies persist as a public health burden in the State of Palestine. To replace current iron-folic acid (IFA) with a multiple micronutrient supplement (MMS) providing a Recommended Dietary Allowance of 15 essential vitamins and minerals as standard of antenatal care (ANC) in UNWRA clinics and hot spots serving pregnant women in the Gaza (n = 22) in 2021–2 and West Bank (n = 44) in 2022–3.

Methods

MMS is planned to start in Gaza in the Fall of 2021, where UNRWA antenatal services reach ∼38,000 pregnant women with IFA each year; ∼97% of whom attended ANC ≥ 4 times². Implementation will follow a randomized, step-wedge procedure whereby MMS will start in the 1^st 11 clinics, and six months later, the 2^nd group of 11 clinics, providing a design for monitoring and comparing the new MMS to existing IFA programs during an initial 6–8 month period.

Results

Outcomes will include indicators of adoption, acceptability, coverage, adherence, fidelity, cost-efficiencies and, as a routine clinical outcome, late pregnancy anemia.

Conclusions

Maternal micronutrient deficiencies are common in Palestine³, meriting replacing IFA with MMS. This research protocol will evaluate implementation in the Gaza Strip to provide guidance for launching and improving antenatal MMS delivery throughout the UNRWA health system.

Food Fortification: The Advantages, Disadvantages and Lessons from Sight and Life Programs

Deficiencies in one or more micronutrients such as iron, zinc, and vitamin A are widespread in low- and middle-income countries and compromise the physical and cognitive capacity of millions of people. Food fortification is a cost-effective strategy with demonstrated health, economic and social benefits. Despite ongoing debates globally and in some countries regarding the performance and safety of food fortification, the practice offers significant benefits across each of the main vehicles for food fortification (large-scale food fortification, biofortification and point-of-use or home fortification) ranging from reducing the prevalence of nutritional deficiencies and economic benefits to societies and economies. Using Sight and Life's global and national experiences in implementing food fortification efforts, we demonstrate how different programs in LMICs have successfully addressed challenges with food fortification and in doing so, find that these efforts are most successful when partnerships are formed that include the public and private sector as well as other parties that can provide support in key areas such as advocacy, management, capacity building, implementation and regulatory monitoring.

This article is based on a session at ASN 2019 entitled Nutrients, Foods, Diets, People: Promoting Healthy Eating. A summary of the 4 presentations at this session is included in this article. The overarching themes that link these 4 presentations are sustainability and food systems. The subjects range from newer definitions of healthy eating to linking sustainable production to sustainable consumption. Two of the papers discuss the importance of the cost of a healthy diet and information as facilitators or barriers to consuming a healthy diet.

Vitamin E Deficiency Is Associated with Reduced Handgrip Strength in Rural Nepalese Children

Objectives

Vitamin E deficiency (VED), common in areas of rural South Asia, can affect neuromuscular health. This study determined the extent of VED and its association with neuromuscular function, indicated by hand grip strength, in Nepalese school aged children.

Methods

This cross-sectional study was conducted in a birth cohort of 6–8 year old children, born during an earlier maternal micronutrient trial, in Sarlahi District in the southern plains (Tarai) of Nepal. Assessments included anthropometry (height, weight, MUAC), handgrip strength by hydraulic dynamometry, plasma α- and γ-tocopherol concentrations by HPLC, other nutritional and inflammatory biomarkers, diet and SES. Data were analyzed using descriptive, bivariate and multivariable regression analyses.

Results

In 998 children, mean (+SD) α- and γ-tocopherol levels were 12.21 (+3.27) μmol/L and 1.50 (+0.70), μmol/L respectively. α-Tocopherol distributions were comparable in females (12.34 ± 3.29 μmol/L) and males (12.09 ± 3.24), with 51.9% of all children classified as VED (plasma α-tocopherol < 12 μmol/L). Plasma γ-tocopherol was higher in females than males (1.56 ± 0.72 vs 1.44 ± 0.67, P < 0.01). Handgrip strength (in kg) was higher in males (7.25 ± 2.14) than females (6.44 ± 2.00) (P < 0.001), which also increased with age. In a continuous multivariable model, adjusted for sex and age, handgrip strength increased with plasma α-tocopherol (βα = 0.054 kg/μmol/L (95% CI: 0.0149–0.0926), P < 0.001). Age-sex adjusted handgrip strength was 0.328 (95% CI: 0.015–0.093) kg lower in VED vs non-deficient children (P < 0.01), but was unrelated to plasma γ-tocopherol. There were no interactions in handgrip strength and vitamin E status by sex.

Conclusions

Vitamin E deficiency is common and is associated with neuromuscular weakness in young, school aged children in southern Nepal, evident by a lower handgrip strength.

The True Value of Spirulina

Algae products are attracting growing interest due to their pleasant taste and their high contents in protein, essential amino acids, vitamins, and minerals. Specifically, spirulina products are widely promoted for their high vitamin B₁₂ content. So far, knowledge regarding the contamination with cyanotoxins, heavy metals, pesticides, or polycyclic aromatic hydrocarbons (PAHs) is scarce, although some studies reported high contaminant levels in spirulina products. The regular intake of spirulina, and very likely other algae products as well, as a dietary supplement in the gram range demands a closer monitoring of potentially harmful constituents.

Perspective: Integration to Implementation (I-to-I) and the Micronutrient Forum-Addressing the Safety and Effectiveness of Vitamin A Supplementation

An ongoing challenge to our ability to address the role of food and nutrition in health promotion and disease prevention is how to design and implement context-specific interventions and guidance that are safe, efficacious, and avoid unintended consequences. The integration to effective implementation (I-to-I) concept is intended to address the complexities of the global health context through engagement of the continuum of stakeholders involved in the generation, translation, and implementation of evidence to public health guidance/programs. The I-to-I approach was developed under the auspices of the Micronutrient Forum and has been previously applied to the question of safety and effectiveness of interventions to prevent and treat nutritional iron deficiency. The present article applies the I-to-I approach to questions regarding the safety and utility of large-dose vitamin A supplementation programs, and presents the authors' perspective on key aspects of the topic, including coverage of the basic and applied biology of vitamin A nutrition and assessment, clinical implications, and an overview of the extant data with regard to both the justification for and utility of available intervention strategies. The article includes some practical considerations based on specific country experiences regarding the challenges of implementing vitamin A-related programs. This is followed by an overview of some challenges associated with engagement of the enabling communities that play a critical role in the implementation of these types of public health interventions. The article concludes with suggestions for potential approaches to move this important agenda forward.

Inadequacy of nutrients and contaminants found in porridge-type complementary foods in Rwanda

Child malnutrition remains persistently high in Rwanda. Complementary foods play a key role in young child nutrition. This study explores the quality and safety of complementary food products available in the Rwandan market. Ten of the most consumed porridge-type complementary food products in Rwanda have been analysed. Mean values of macronutrient and micronutrient contents were compared against three international standards and evaluated against label claims. Mean mycotoxin, microbiological, and pesticide contamination were compared with maximum tolerable limits. Mean energy density (385 kcal/100 g) and total fat content (7.9 g/100 g) were lower than all three international benchmarks. The mean fibre content of 8.5 g/100 g was above the maximum recommended amount of Codex Alimentarius and more than double the amount claimed on labels. Mean levels of vitamin A (retinyl palmitate, 0.54 mg/100 g) and vitamin E (α-tocopherol, 3.7 mg/100 g) fell significantly short of all three standards, whereas calcium and zinc requirements were only partially met. Average iron content was 12.1 mg/100 g. The analysis revealed a mean aflatoxin contamination of 61 μg/kg, and high mold and yeast infestation. Escherichia coli and pesticide residues were found, whereas no heavy metals could be quantitated. Overall, complementary food products in Rwanda show inadequate nutrient contents and high aflatoxin and microbial contamination levels. Improved regulation and monitoring of both local and imported products are needed to improve the quality and safety of complementary foods in Rwanda.

Translational and Implementation Research to Bridge Evidence and Implementation

BACKGROUND

The role of science in guiding interventions and programs and contributing to progress in achieving global targets is undeniable. In public health nutrition, biological research in the past century focused largely on single nutrients and provided the basis for addressing nutritional deficiencies. This focus has now expanded to consider evidence including, but not limited, to knowledge about food, diet, behavior, context, and culture. The complex double burden of malnutrition will need to be addressed through a wider lens that appreciates the multiple and interrelated facets that underpin it.

SUMMARY

Despite the acknowledged importance of translational research in improving nutritional outcomes, significant gaps remain in the process leading from science to practice. This article sheds light on 2 examples that demonstrate this, namely, anemia and stunting. Further, much work is still required to translate the current evidence base into effective actions that result in impact at scale, pointing toward the need for more implementation research in nutrition. Key Messages: While discoveries may take time to surface and implementers are impatient to address the challenge at hand, it is essential to identify and deploy the best available evidence while continuously advancing the evidence base, and to seek the right balance between action and inaction.

A Systematic Review Investigating the Relation Between Animal-Source Food Consumption and Stunting in Children Aged 6-60 Months in Low and Middle-Income Countries

Animal-source foods (ASFs) are a food group of interest for interventions aimed at reducing stunting and other inadequate growth measures in early childhood. The aim of this systematic review was to examine the relation between ASF consumption and stunting in children aged 6-60 mo in low- and middle-income countries (LMICs). The secondary aim was to examine the relation between ASF consumption and other indicators of growth and development (length/height, weight, head circumference, and anemia). A search of the peer-reviewed and grey literature published from January 1980 to June 2017 was conducted. Databases searched included CINAHL, Embase, Global Index Medicus, PubMed, and Web of Science. There were 14,783 records and 116 full text articles dual screened; 21 studies were included in the review and were dual evaluated for risk of bias (RoB). The relation between ASF and stunting (length- or height-for-age z-score←2) was examined in randomized-controlled trials [(RCTs), n = 3] and cross-sectional studies (n = 4) only; ASF reduced stunting in 1 RCT and was associated with reduced stunting in 1 cross-sectional study. We did not identify any longitudinal cohorts that examined this relation. The relation between ASF and secondary indicators length/height, weight, head circumference, and anemia were largely nonsignificant across study designs. The intervention/exposure, comparator, outcome measures, methods, and analyses were highly heterogeneous. Although we did not find a consistent relation between ASF consumption and our primary and secondary outcomes, this may have been a function of inconsistencies in study design. Foods in the whole diet, particularly combination dishes, are inherently difficult to assess. To quantitatively assess the relation between ASF and stunting and other indicators of growth and iron status in early childhood, future research should provide consistency in the definition and quantification of the exposure and outcomes allowing for interstudy quantitative comparisons.

Including 60 mg Elemental Iron in a Multiple Micronutrient Supplement Blunts the Increase in Serum Zinc after 12 Weeks of Daily Supplementation in Predominantly Anemic, Nonpregnant Cambodian Women of Reproductive Age

BACKGROUND

Multiple micronutrient (MMN) supplementation may result in interaction effects due to competing absorptive pathways of trace elements.

OBJECTIVES

The aim of this study was to investigate the effect of MMN supplementation with or without iron on serum zinc, selenium, and copper concentrations in Cambodian women.

METHODS

In a 2 × 2 factorial double-blind randomized 12-wk trial, predominantly anemic, nonpregnant women (aged 18-45 y) received daily 60 mg of iron (Fe; n = 201); 14 other micronutrients including zinc (15 mg), selenium (65 μg), and copper (2 mg), but no iron (MMN; n = 202); 60 mg iron plus MMN (Fe + MMN; n = 206); or a placebo (n = 200). Fasting morning blood was collected at baseline and 12 wk from women in 26 villages in Kampong Chhnang province. Serum zinc, selenium, and copper concentrations (secondary outcomes of the randomized controlled trial) were measured using inductively coupled plasma mass spectrometry. Generalized linear regression was used to estimate intervention effects [β coefficient (95% CI)] for Fe (with or without MMN) and MMN (with or without Fe) after testing for the presence of an Fe × MMN interaction.

RESULTS

A total of 760 women completed the trial. Zinc deficiency prevalence at baseline was 45% (inflammation-adjusted serum zinc <10.7 μmol/L). A significant Fe × MMN interaction (P = 0.02) was detected in the 2 × 2 analysis with serum zinc concentration as the outcome: the MMN group had a higher mean serum zinc concentration at 12 wk (12.3 μmol/L; 95% CI: 12.2, 12.4 μmol/L) compared with all other groups, and the Fe + MMN group had a higher mean serum zinc concentration (11.6 μmol/L; 95% CI: 11.5, 11.7 μmol/L) compared with the Fe group (11.0 μmol/L; 95% CI: 10.9, 11.0 μmol/L) and the placebo group (11.2 μmol/L; 95% CI: 11.1, 11.4 μmol/L).

CONCLUSIONS

The inclusion of 60 mg iron in the daily MMN formulation may be interfering with the absorption and/or metabolism of supplemental zinc in Cambodian women. This is of particular concern when MMN supplementation is implemented in populations with risk of zinc deficiency. This trial was registered at clinicaltrials.gov as NCT-02481375.

Inadequacy of Nutrients, Contaminants, and Label Claims Found in Porridge-type Complementary Foods in Rwanda (P10-042-19)

Objectives

Child malnutrition remains persistently high in Rwanda. Complementary foods play a key role in young child nutrition. This study explores the quality and safety of complementary food products available in the Rwandan market.

Methods

Nine of the most consumed porridge-type complementary food products in Rwanda were analyzed. A total of 17 samples, including local brands and brands from Uganda and Kenya, as well as imports from Switzerland and France, were purchased in commercial retail outlets in the Kigali area and tested. Mean values of macronutrient and micronutrient contents were compared against three international standards and evaluated against label claims. Mean mycotoxin, microbiological, pesticide, and heavy metal contamination were compared to maximum tolerable limits.

Results

Mean energy density (385 kcal/100 g) and total fat content (7.9 g/100 g) were lower than all three international benchmarks. The mean fiber content of 8.5 g/100 g was above the maximum recommended amount of Codex Alimentarius and more than double the amount claimed on labels. Mean levels of vitamin A (retinyl palmitate, 0.54 mg/100 g) and vitamin E (α-tocopherol, 3.7 mg/100 g) fell significantly short of all three standards, whereas calcium and zinc requirements were only partially met. Average iron content was 12.1 mg/100 g. The analysis revealed a mean aflatoxin contamination of 61 μg/kg, and high mold and yeast infestation. E.coli and pesticide residues were found, whereas no heavy metals could be quantitated in the samples.

Conclusions

Overall, complementary food products in Rwanda show inadequate nutrient contents and high aflatoxin and microbial contamination levels. Adequately implemented and enforced quality and safety standards are required to ensure complementary foods contribute to young child growth and prevent foodborne illness in this particularly vulnerable population.

Review of the evidence regarding the use of antenatal multiple micronutrient supplementation in low- and middle-income countries

Inadequate micronutrient intakes are relatively common in low- and middle-income countries (LMICs), especially among pregnant women, who have increased micronutrient requirements. This can lead to an increase in adverse pregnancy and birth outcomes. This review presents the conclusions of a task force that set out to assess the prevalence of inadequate micronutrient intakes and adverse birth outcomes in LMICs; the data from trials comparing multiple micronutrient supplements (MMS) that contain iron and folic acid (IFA) with IFA supplements alone; the risks of reaching the upper intake levels with MMS; and the cost-effectiveness of MMS compared with IFA. Recent meta-analyses demonstrate that MMS can reduce the risks of preterm birth, low birth weight, and small for gestational age in comparison with IFA alone. An individual-participant data meta-analysis also revealed even greater benefits for anemic and underweight women and female infants. Importantly, there was no increased risk of harm for the pregnant women or their infants with MMS. These data suggest that countries with inadequate micronutrient intakes should consider supplementing pregnant women with MMS as a cost-effective method to reduce the risk of adverse birth outcomes.

Implementation Science in Nutrition: Concepts and Frameworks for an Emerging Field of Science and Practice

Malnutrition in all its forms has risen on global and national agendas in recent years because of the recognition of its magnitude and its consequences for a wide range of human, social, and economic outcomes. Although the WHO, national governments, and other organizations have endorsed targets and identified appropriate policies, programs, and interventions, a major challenge lies in implementing these with the scale and quality needed to achieve population impact. This paper presents an approach to implementation science in nutrition (ISN) that builds upon concepts developed in other policy domains and addresses critical gaps in linking knowledge to effective action. ISN is defined here as an interdisciplinary body of theory, knowledge, frameworks, tools, and approaches whose purpose is to strengthen implementation quality and impact. It includes a wide range of methods and approaches to identify and address implementation bottlenecks; means to identify, evaluate, and scale up implementation innovations; and strategies to enhance the utilization of existing knowledge, tools, and frameworks based on the evolving science of implementation. The ISN framework recognizes that quality implementation requires alignment across 5 domains: the intervention, policy, or innovation being implemented; the implementing organization(s); the enabling environment of policies and stakeholders; the individuals, households, and communities of interest; and the strategies and decision processes used at various stages of the implementation process. The success of aligning these domains through implementation research requires a culture of inquiry, evaluation, learning, and response among program implementers; an action-oriented mission among the research partners; continuity of funding for implementation research; and resolving inherent tensions between program implementation and research. The Society for Implementation Science in Nutrition is a recently established membership society to advance the science and practice of nutrition implementation at various scales and in varied contexts.

The association between active tobacco use during pregnancy and growth outcomes of children under five years of age: a systematic review and meta-analysis

Background

Despite considerable global efforts to reduce growth faltering in early childhood, rates of stunting remain high in many regions of the world. Current interventions primarily target nutrition-specific risk factors, but these have proven insufficient. The objective of this study was to synthesize the evidence on the relationship between active tobacco use during pregnancy and growth outcomes in children under five years of age.

Methods

In this systematic review and meta-analysis, six online databases were searched to identify studies published from January 1, 1980, through October 31, 2016, examining the association between active tobacco use during pregnancy and small-for-gestational age (SGA), length/height, and/or head circumference. Ecological studies were not included. A meta-analysis was conducted, and subgroup analyses were carried out to explore the effect of tobacco dosage.

Results

Among 13,189 studies identified, 210 were eligible for inclusion in the systematic review, and 124 in the meta-analysis. Active tobacco use during pregnancy was associated with significantly higher rates of SGA (pooled adjusted odds ratio [AORs] = 1.95; 95% confidence interval [CI]: 1.76, 2.16), shorter length (pooled weighted mean difference [WMD] = 0.43; 95% CI: 0.41, 0.44), and smaller head circumference (pooled WMD = 0.27; 95% CI: 0.25, 0.29) at birth. In addition, a dose-response effect was evident for all growth outcomes.

Conclusion

Tobacco use during pregnancy may represent a major preventable cause of impaired child growth and development.

Situation analysis of procurement and production of multiple micronutrient supplements in 12 lower and upper middle-income countries

Globally, there are few vitamin and mineral ingredient manufacturers. To support local, in-country or regional procurement and production of multiple micronutrient supplements (MMS), the following production scenarios are possible: (a) straight ingredients of vitamins and minerals forms imported or locally produced that are mixed, tableted, or encapsulated and packaged by a local manufacturer; (b) import or local production of a vitamin and minerals premix that is tableted or encapsulated and packaged locally; (c) import of a bulk, finished product (tablets or capsules) that is packaged and branded; and (d) or import of a branded packaged product. This paper is a situation analysis of the market, manufacturing, and policy factors that are driving the production of MMS in 12 lower and upper middle-income countries. Key informants completed a self-administered structured questionnaire, which examined the local context of products available in the market and their cost, regulations and policies, in Brazil, Colombia, Guatemala, Mexico, Peru, Bangladesh, India, Vietnam, Ghana, Kenya, Nigeria, and South Africa. Our study found that although most countries have the capacity to produce locally MMS, the major barriers observed for sustainable and affordable production include (a) poor technical capacity and policies for ensuring quality along the value chain and (b) lack of policy coherence to incentivize local production and lower the manufacture and retail price of MMS. Also, better guidelines and government oversight will be required because not one country had an MMS formulation that matched the globally recommended formulation of the United Nations Multiple Micronutrient Preparation (UNIMMAP).

Increasing egg availability through smallholder business models in East Africa and India

Availability and consumption of eggs, especially in Sub-Saharan Africa and Asia, is low despite their apparent benefits. We investigated constraints in egg production in four countries; Kenya, Ethiopia, Malawi, and India and identified five business models that are viable and sustainable. They are (a) micro-franchising, (b) microfinancing, (c) co-operative farming, (d) enterprise development, and (e) out-grower model. All of them involve smallholder farmers to increase egg production. These farmers have access to soft loans and use improved inputs and extension services to varying degrees. Inputs include resilient breeds of day-old chicks or point-of-lay hens, feed, vaccines, medicines, and housing. Outgrower and enterprise development models have a significant potential of rapidly increasing egg yields, achieve self-sufficiency, operate at or near scale, and provide a high income for the farmers. This study shows how a range of actors in commercial, not-for-profit and microfinance sectors with specialized skills, can facilitate the transformation of the egg production sector. Specific skills include brooding (hatchery operations), feed milling, aggregation, and training of smallholder farmers or large-scale rearing. The five archetypes we describe here are promising ways to increase egg availability in rural areas.

Low serum ω-3 and ω-6 polyunsaturated fatty acids and other metabolites are associated with poor linear growth in young children from rural Malawi

Background: Stunting affects ∼25% of children <5 y of age and is associated with impaired cognitive and motor development and increased morbidity and mortality. The pathogenesis of stunting is poorly understood.Objective: The purpose of this study was to identify altered metabolic pathways associated with child stunting.Design: We measured 677 serum metabolites using liquid chromatography-tandem mass spectrometry in a cross-sectional study of 400 Malawian children aged 12-59 mo, of whom 62% were stunted.Results: A low height-for-age z score (HAZ) was associated with lower serum concentrations of 1) ω-3 (n-3) and ω-6 (n-6) polyunsaturated fatty acids (PUFAs), 2) sulfated neurosteroids, which play a role in brain development, 3) carnitine, a conditionally essential nutrient with an important role in the carnitine shuttle for the metabolism of fatty acids and energy production, and 4) γ-glutamyl amino acids, which represent an altered γ-glutamyl cycle of glutathione metabolism. A low HAZ was associated with significantly higher serum concentrations of 5 biomarkers related to cigarette smoke exposure.Conclusions: This metabolomics study shows a cross-sectional association between stunting and low serum ω-3 and ω-6 long-chain PUFAs, which are essential for growth and development; low sulfated neurosteroids, which play a role in brain development; low carnitine, which is essential for β-oxidation of fatty acids; alterations in glutathione metabolism; and increased serum metabolites that are associated with secondhand tobacco smoke exposure. This trial was registered at www.controlled-trials.com as ISRCTN14597012.

The effect of oral iron with or without multiple micronutrients on hemoglobin concentration and hemoglobin response among nonpregnant Cambodian women of reproductive age: a 2 x 2 factorial, double-blind, randomized controlled supplementation trial

Background: Despite a high prevalence of anemia among nonpregnant Cambodian women, current reports suggest that iron deficiency (ID) prevalence is low. If true, iron supplementation will not be an effective anemia reduction strategy.Objective: We measured the effect of daily oral iron with or without multiple micronutrients (MMNs) on hemoglobin concentration in nonpregnant Cambodian women screened as anemic.Design: In this 2 × 2 factorial, double-blind, randomized trial, nonpregnant women (aged 18-45 y) with hemoglobin concentrations ≤117 g/L (capillary blood) were recruited from 26 villages in Kampong Chhnang province and randomly assigned to receive 12 wk of iron (60 mg; Fe group), MMNs (14 other micronutrients; MMN group), iron plus MMNs (Fe+MMN group), or placebo capsules. A 2 × 2 factorial intention-to-treat analysis with the use of a generalized mixed-effects model was used to assess the effects of iron and MMNs and the interaction between these factors. Results: In July 2015, 809 women were recruited and 760 (94%) completed the trial. Baseline anemia prevalence was 58% (venous blood). Mean (95% CI) hemoglobin concentrations at 12 wk in the Fe, MMN, Fe+MMN, and placebo groups were 121 (120, 121), 116 (116, 117), 123 (122, 123), and 116 (116, 117) g/L, with no iron × MMN interaction (P = 0.66). Mean (95% CI) increases in hemoglobin were 5.6 g/L (3.8, 7.4 g/L) (P < 0.001) among women who received iron (n = 407) and 1.2 g/L (-0.6, 3.0 g/L) (P = 0.18) among women who received MMNs (n = 407). The predicted proportions (95% CIs) of women with a hemoglobin response (≥10 g/L at 12 wk) were 19% (14%, 24%), 9% (5%, 12%), 30% (24%, 35%), and 5% (2%, 9%) in the Fe, MMN, Fe+MMN, and placebo groups, respectively.Conclusions: Daily iron supplementation for 12 wk increased hemoglobin in nonpregnant Cambodian women; however, MMNs did not confer additional significant benefit. Overall, ∼24% of women who received iron responded after 12 wk; even fewer would be likely to respond in the wider population. This trial was registered at clinicaltrials.gov as NCT02481375.

Environmental Enteric Dysfunction is Associated with Carnitine Deficiency and Altered Fatty Acid Oxidation

BACKGROUND

Environmental enteric dysfunction (EED), a condition characterized by small intestine inflammation and abnormal gut permeability, is widespread in children in developing countries and a major cause of growth failure. The pathophysiology of EED remains poorly understood.

METHODS

We measured serum metabolites using liquid chromatography-tandem mass spectrometry in 400 children, aged 12-59months, from rural Malawi. Gut permeability was assessed by the dual-sugar absorption test.

FINDINGS

80.7% of children had EED. Of 677 serum metabolites measured, 21 were negatively associated and 56 were positively associated with gut permeability, using a false discovery rate approach (q<0.05, p<0.0095). Increased gut permeability was associated with elevated acylcarnitines, deoxycarnitine, fatty acid β-oxidation intermediates, fatty acid ω-oxidation products, odd-chain fatty acids, trimethylamine-N-oxide, cystathionine, and homocitrulline, and with lower citrulline, ornithine, polyphenol metabolites, hippurate, tryptophan, and indolelactate.

INTERPRETATION

EED is a syndrome characterized by secondary carnitine deficiency, abnormal fatty acid oxidation, alterations in polyphenol and amino acid metabolites, and metabolic dysregulation of sulfur amino acids, tryptophan, and the urea cycle. Future studies are needed to corroborate the presence of secondary carnitine deficiency among children with EED and to understand how these metabolic derangements may negatively affect the growth and development of young children.
