Estimating the Health and Economic Benefits of Universal Salt Iodization Programs to Correct Iodine Deficiency Disorders.

Background: There has been tremendous progress over the past 25 years to control iodine deficiency disorders (IDDs) through universal salt iodization (USI). In 2019, using the median urinary iodine concentration (MUIC), only 19 countries in the world are classified as iodine deficient; in contrast in 1993, using the total goiter rate (TGR), 113 countries were classified as iodine deficient. However, few analyses have tried to quantify the global health and economic benefits of USI programs, and the shift from TGR to MUIC as the main indicator of IDDs complicates assessment of progress. Methods: We used a novel approach to estimate the impact of USI on IDDs, applying a regression model derived from observational data on the relationship between the TGR and the MUIC from 24 countries. The model was used to generate hypothetical national TGR values for 2019 based on current MUIC data. TGR in 1993 and modeled TGR in 2019 were then compared for 139 countries, and using consequence modeling, the potential health and economic benefits realized between 1993 and 2019 were estimated. Results: Based on this approach, the global prevalence of clinical IDDs (as assessed by the TGR) fell from 13.1% to 3.2%, and 720 million cases of clinical IDDs have been prevented by USI (a reduction of 75.9%). USI has significantly reduced the number of newborns affected by IDDs, with 20.5 million cases prevented annually. The resulting improvement in cognitive development and future earnings suggest a potential global economic benefit of nearly $33 billion. However, 4.8 million newborns will be affected by IDDs in 2019, who will experience life-long productivity losses totaling a net present value of $12.5 billion. Conclusions: The global improvements in iodine status over the past 25 years have resulted in major health and economic benefits, mainly in low- and middle-income countries. Efforts should now focus on sustaining this achievement and expanding USI to reach the continuing large number of infants who remain unprotected from IDDs.

The Economic Burden of Malnutrition in Pregnant Women and Children under 5 Years of Age in Cambodia.

Malnutrition is locked in a vicious cycle of increased mortality, poor health, impaired cognitive development, slow physical growth, reduced learning capacity, inferior performance, and ultimately lower adult work performance and productivity. The consensus of global scientific evidence indicates that lowering the rates of malnutrition will be an indispensable component of any successful program to raise the quality of human capital and resources. This study used a "consequence model" to apply the coefficient risk-deficit on economic losses, established in the global scientific literature, to Cambodian health, demographic, and economic data to develop a national estimate of the value of economic losses due to malnutrition. The impact of the indicators of malnutrition analyzed represent a burden to the national economy of Cambodia estimated at 266 million USD annually (1.7% of GDP). Stunting is reducing the Cambodian economic output by more than 120 million USD, and iodine deficiency disorders alone by 57 million USD. This economic burden is too high in view of Cambodia's efforts to drive economic development. The government should rapidly expand a range of low-cost effective nutrition interventions to break the current cycle of increased mortality, poor health and ultimately lower work performance, productivity, and earnings.

The economic consequences of malnutrition in Cambodia, more than 400 million US dollar lost annually.

BACKGROUND: Cambodia is among the 28 worst countries globally with the highest rates of childhood malnutrition. The aim of the assessment was to apply published evidence associating malnutrition and a variety of functional consequences to project economic implications of this high rate of childhood malnutrition. Such information is vital to advocate for appropriate programs and action plan to reduce malnutrition (from severe stunting to micronutrient deficiencies). METHODS: This exercise used a "consequence model" to apply these "coefficients of loss" established in the global scientific literature to Cambodia health, demographic and economic data to develop a national estimation of the economic losses link to malnutrition. RESULTS: The impact of the indicators of malnutrition analysed represent a burden to the national economy of Cambodia estimated at more than $400 million annually -2.5% of GDP. Micronutrient deficiencies suggest deficits in the quality of the diet - representing a national burden of more than $200 million annually while breastfeeding behaviours account for 6% of the burden. 57% of the losses emerge from indicators measured in children, while 43% of losses are from indicators independent of childhood measurements - indicators of maternal behaviour along with maternal and adult nutrition. CONCLUSIONS: Given the low cost of interventions and the high baseline losses, investment in nutrition programs in Cambodia is likely to offer high returns and attractive benefit cost ratios. Since nearly half the losses are determined prior to the birth of the child, this has implications for targeting and timing of programs.

Rice fortification: an emerging opportunity to contribute to the elimination of vitamin and mineral deficiency worldwide.

Vitamin and mineral deficiencies are ranked among the top causes of poor health and disability in the world. These deficiencies damage developing brains, impair learning ability, increase susceptibility to infections, and reduce the work productivity of nations. Food fortification is a sustainable, cost-effective approach to reducing vitamin and mineral deficiency. As the staple food for an estimated 3 billion people, rice has the potential to fill an obvious gap in current fortification programs. In recent years, new technologies have produced fortified rice kernels that are efficacious in reducing vitamin and mineral deficiency. There are opportunities to fortify a significant share of rice that comes from large mills supplying centralized markets and national welfare programs in major rice-growing countries. The rice export markets, which handle 30 million MT of rice annually, also present a key fortification opportunity. The cost of fortifying rice is only 1.5% to 3% of the current retail price of rice. Countries that mandate rice fortification have the strongest evidence for achieving wide coverage and impact. The Rice Fortification Resource Group (RiFoRG), a global network of public and private partners that offers technical and advocacy support for rice fortification, has a vision of promoting rice fortification worldwide. It has a targeted approach, engaging multisector partners in key countries where the opportunities are greatest and there is receptivity to early adoption of large-scale rice fortification. The challenges are real, the imperative to address them is powerful, and the opportunities to deliver the promise of rice fortification are clear.

Nutritional enhancement of US Title II food aid products.

BACKGROUND: Food aid provided by the United States has saved the lives of the vulnerable for many years. Recognizing the need for a thorough review of product formulations and specifications, the US Agency for International Development (USAID) commissioned a 2-year assessment of quality issues relating to Title II food aid products. This article presents findings and recommendations of that review relating to product enhancements. OBJECTIVE: The core question addressed was: Are current commodity specifications for enriched FBFs appropriate in light of evolving nutritional science and food fortification technology, or do they need to be updated? METHODS: Empirical data were derived from a number of sources, including a survey of Title II implementing partners focusing on procurement and logistics, and uses of FBFs and other foods. Input of implementing partners, civil society, and donor organizations was obtained through individual consultations, international and small group meetings. More than 400 individuals accessed the project's website. The project convened a panel of experts in food technology and science, food policy, law, industry, medicine, development and humanitarian work, and the maritime industry, and held regular joint meetings with USDA and USAID. The draft report was widely disseminated and posted on the website. RESULTS AND CONCLUSIONS: The findings of this research led to the following broad areas of improvement in US Title II food aid products: 1) Improve the formulation of existing FBF products used in Title II programming. This includes the addition of a dairy source of protein to products targeted to children 6 to 24 months of age, pregnant and lactating women, wasted children, and wasted individuals undergoing HIV/AIDS treatment. 2) Upgrade the vitamin and mineral mixes used and diversify approaches to addressing micronutrient needs. Enhance the composition of premixes used to fortify blended foods as well as milled grains and vegetable oil; facilitate shipping offortificant premix with bulk cereals for in-country fortification; and develop micronutrient powders (sachets) and other point-of-use fortification options. 3) Develop or adopt non-cereal-based (e.g., lipid-based) products for the management of nutritional deficiencies. This is an argument for more choice among appropriate tools, not for discarding products that have already shown their value over many years. It also does not reduce the need to maintain a focus on supplying high volumes of quality grains as the main staple in food aid baskets.

Selection and use of US Title II food aid products in programming contexts.

BACKGROUND: Food aid provided by the United States has saved lives for almost two centuries. Delivering the right products is important, but of equal concern are the ways in which products are delivered and to whom. OBJECTIVE: The study addresses how food products are currently used, whether interventions are appropriate to achieve nutrition objectives, and whether nutrition targets could be met more cost-effectively with a different mix of products or programs. METHODS: The team conducted consultations with a broad range of stakeholders. A survey of Title II implementing partners was conducted, focusing on procurement and logistics, and uses of FBFs and other foods. Input of implementing partners, civil society, and donor organizations was obtained through individual consultations, international and small group meetings. More than 400 individuals accessed the project's website. The project convened a panel of experts in food technology and science, food policy, law, industry, medicine, development and humanitarian work, and the maritime industry, and held regular joint meetings with USDA and USAID. The draft report was widely disseminated and posted on the website. RESULTS AND CONCLUSIONS: There is wide variation in the quantities of fortified blended foods provided to target populations. Most of these foods are used in health/nutrition programs, but they are also used in general family rations or as an incentive or pay. Clearer programming guidance and improved decision tools are needed to match products to nutrition goals, and programs should consider delivering nutrients across a basket of commodities, not single products. The evidence base for the effectiveness and cost-effectiveness of specific foods and programs needs to be strengthened and should be supported by FFP Research is needed to provide guidance on nutrition support for HIV/AIDS. Additional investments are needed in effective behavior change communication.

Enhancing processes for introduction, production, quality assurance, and delivery of US Title II food aid products.

BACKGROUND: Enacted in 1950, Public Law 480 (PL480) dramatically increased the volume of U.S.food aid and the scope of interventions it supports. Billions of dollars have been invested, both to enhance the diets of chronically undernourished people in development settings, and to support nutritional needs during conflicts and natural disasters. OBJECTIVE: Review the institutional processes-from procurement to delivery-that support this programming. METHODS: We examined the systems that govern and oversee the many components of food aid programming and the extent to which they support a whole-of-government, multi-agency food aid agenda. We conducted consultations with US government employees and contractors, academics, industry representatives, donor agency staff United Nations personnel, and field-level food aid programming technical staff from many countries. A survey of USAID implementing partners conducted among 64 responding offices in 40 countries provided data on the use and effectiveness of enriched, fortified, or blended Title II commodities, the use of new commodities, and related procurement or logistics aspects. Expert panels provided input and feedback throughout the process. RESULTS: We identified potential improvements to overall delivery and cost-effectiveness of USAID programming to better meet the nutrition needs of beneficiaries. Options include changes in product formulation, the range of products provided, and/or the modes of product approval, processing, procurement, and distribution. This research points to several improvements in processes related to food aid: 1) Establish an interagency committee to oversee all government interests in the food aid agenda through an ongoing review process. 2) Enhance processes and quality assurance along the product value chain including the importance of effective interaction with the private sector to incorporate industry best practices and create public-private partnerships to promote product innovations. 3) Strengthen the evidence base for innovations in products, programming approaches, and institutional processes. CONCLUSION: Successful programming requires knowledge and understanding of the unit cost of impact, not simply tonnage and "numbers of hungry people fed". Empirical rigor is essential; any significant program changes, including those recommended here, should be tested and monitored.
