RESUMEN

Quality complementary feeding (CF) of infants and young children is key to their growth and development. But in Jordan, providing appropriate CF remains a challenge. This study assesses trends in infant and young child feeding (IYCF) practices, and consumption by infants and young children aged 6-23 months of breast milk substitutes (BMSs), sugar-sweetened beverages (SSBs), and micronutrient-rich foods in Jordan from 1990 to 2017. We combined dietary data on infants and young children from six Demographic and Health Surveys (DHS) (n = 14,880 children) to compute IYCF indicators. The latter included minimum dietary diversity (MDD), minimum meal frequency (MMF), and minimum acceptable diet (MAD), as well as intake of micronutrient-rich foods and food groups, specific SSBs, and infant formula. We conducted trend analyses using logistic regression models adjusted for child's age in month, child age squared, governorates, urban/rural residence, mother's educational attainment, and household wealth quintiles. We found that the proportion of consumption of micronutrient-rich food groups declined significantly between 1990 and 2017, with fewer infants and young children consuming eggs (OR = 0.39, p ≤ 0.001, 2002 reference), meat, poultry, and fish (OR = 0.25, p ≤ 0.001, 2002 reference), dairy (OR = 0.59, p ≤ 0.001, 2002 reference) and Vitamin A-rich fruits and vegetables (OR = 0.66, p ≤ 0.001, 2002 reference). Conversely, there was increased use of BMSs and sugar-sweetened juices that paralleled a decline in the share of infants and young children meeting appropriate CF practices and consuming micronutrient-rich foods and food groups. By 2017, children aged 6-23 months were significantly less likely to meet MDD, MMF, and subsequently MAD; the odds of consuming BMSs were almost three times the reference (OR = 3.8, p ≤ 0.001, 1990 reference), as were the odds of consuming sugar sweetened juices  (OR = 3.63, p ≤ 0.001, 1990 reference). Food insecurity and undernutrition are low in Jordan; however, overweight and obesity rates are increasing concurrently as are micronutrient deficiencies. This highlights the need for policymakers to address factors at individual and household levels (behaviours and practices) as well as environmental issues (increasing access to unhealthy and ultraprocessed foods).

RESUMEN

OBJECTIVE: To implement and measure the effects of a multi-level multi-sectoral social behavior change (SBC) intervention in Agago District of Northern Uganda and to determine the potential for scale-up. INTERVENTION: Compare the Nutrition Impact and Positive Practice (NIPP) approach to a NIPP+ approach. The NIPP approach involves nutrition education and SBC, whereas the NIPP+ adds agricultural inputs, training, and tools to support improved farm and water quality practices. The intervention effect will be measured through lower levels of aflatoxin in grain, lower water contamination, and improved knowledge on nutrition and health. DESIGN: This is a three-arm cluster-randomized controlled superiority trial (cRCT). The study arms include the following: group 1: NIPP; group 2: NIPP+, and group 3: control. Groups 1 and 2 will receive a 12-week intervention (NIPP or NIPP+) with active monitoring and longitudinal follow-up at 2, 6, and 12 months post-intervention. Additionally, an in-depth process and performance evaluation of each intervention arm will be undertaken using quantitative and qualitative methods. A total of 60 clusters from 5 subcounties of the Agago district will be randomly selected, and 15 households per cluster will be recruited using specific inclusion/exclusion criteria for a total of 900 households (300/arm). Respondents for the qualitative portion will be purposely selected. ANALYSIS: We will collect data from all participants at 3 time points: baseline, endline, and 12 months post-intervention. The analysis will utilize intent-to-treat (ITT) using the initial randomization of the treatment arms to determine the overall impact of having the NIPP vs. NIPP+ vs. control. Mixed effects models will be used to determine the role of time-variant and invariant individual household, and community characteristics, as well as measures of exposure and integration on key outcome indicators. A difference-in-difference analysis (baseline/endline, baseline/12 months post-intervention, endline/12 months post-intervention) will also be used to triangulate findings.

RESUMEN

BACKGROUND: Moderate acute malnutrition (MAM) affects 33 million children annually. Investments in formulations of corn-soy blended flours and lipid-based nutrient supplements have effectively improved MAM recovery rates. Information costs and cost-effectiveness differences are still needed. OBJECTIVES: We assessed recovery and sustained recovery rates of MAM children receiving a supplementary food: ready-to-use supplementary food (RUSF), corn soy whey blend with fortified vegetable oil (CSWB w/oil), or Super Cereal Plus with amylase (SC + A) compared to Corn Soy Blend Plus with fortified vegetable oil (CSB+ w/oil). We also estimated differences in costs and cost effectiveness of each supplement. METHODS: In Sierra Leone, we randomly assigned 29 health centers to provide a supplement containing 550 kcal/d for ∼12 wk to 2691 children with MAM aged 6-59 mo. We calculated cost per enrollee, cost per child who recovered, and cost per child who sustained recovery each from 2 perspectives: program perspective and caregiver perspective, combined. RESULTS: Of 2653 MAM children (98.6%) with complete data, 1676 children (63%) recovered. There were no significant differences in the odds of recovery compared to CSB+ w/oil [0.83 (95% CI: 0.64-1.08) for CSWB w/oil, 1.01 (95% CI: 0.78-1.3) for SC + A, 1.05 (95% CI: 0.82-1.34) for RUSF]. The odds of sustaining recovery were significantly lower for RUSF (0.7; 95% CI 0.49-0.99) but not CSWB w/oil or SC + A [1.08 (95% CI: 0.73-1.6) and 0.96 (95% CI: 0.67-1.4), respectively] when compared to CSB+ w/oil. Costs per enrollee [US dollars (USD)/child] ranged from $105/child in RUSF to $112/child in SC + A and costs per recovered child (USD/child) ranged from $163/child in RUSF to $179/child in CSWB w/oil, with overlapping uncertainty ranges. Costs were highest per sustained recovery (USD/child), ranging from $214/child with the CSB+ w/oil to $226/child with the SC + A, with overlapping uncertainty ranges. CONCLUSIONS: The 4 supplements performed similarly across recovery (but not sustained recovery) and costed measures. Analyses of posttreatment outcomes are necessary to estimate the full cost of MAM treatment. This trial was registered at clinicaltrials.gov as NCT03146897.

RESUMEN

BACKGROUND: Measures that better describe "healthy" and sustainable recovery during nutritional treatment of children with moderate acute malnutrition (MAM) are needed. OBJECTIVES: We compared changes to body composition among children receiving 1 of 4 specialized nutritious food (SNFs) during treatment of MAM and by recovery and relapse outcomes. METHODS: The study was nested within a prospective, cluster-randomized, community-based, cost-effectiveness trial assessing 4 SNFs to treat children aged 6-59 mo with MAM [midupper arm circumference (MUAC) ≥11.5 cm and <12.5 cm without bipedal edema] in Sierra Leone. Biweekly SNF rations (1 of 3 fortified-blended foods or a lipid-based nutrient supplement) were given until children recovered (MUAC ≥12.5 cm), or up to 7 rations (∼12 wk). Deuterium dilution was used to estimate fat-free mass (FFM) and fat mass (FM) at enrollment and after 4 wk of treatment to ensure similar treatment exposure among the participants. Another MUAC measurement was performed among recovered children 4 wk after program exit to determine whether recovery was sustained. ANOVA, paired t tests, and linear regression models were used to determine significant differences in changes from baseline to 4 wk. RESULTS: Among 312 analyzed participants, mean baseline weight comprised ∼80% FFM; mean weight gained after 4 wk comprised ∼82% FFM. Changes in FM and FFM among 4 SNFs were similar. Children who recovered gained more weight (241%), FFM (179%), and weight-for-height z score (0.44 compared with 0) compared with those who did not recover; sustainers gained 150% more weight. FM gains were positive among recovered children and sustainers, as well as negative among those who did not recover or sustain recovery, but not significantly different. CONCLUSIONS: Four SNFs had similar effects on body composition in children after 4 wk of treatment for MAM, showing a healthy pattern of weight gain, the majority being FFM. Differential responses to treatment underscore a need for further research to provide targets for healthy, sustainable recovery. This trial was registered at clinicaltrials.gov as NCT03146897.

RESUMEN

OBJECTIVE: To assess the effects of food supplementation on improving working memory and additional measures including cerebral blood flow in children at risk of undernutrition. DESIGN: Randomized controlled trial. SETTING: 10 villages in Guinea-Bissau. PARTICIPANTS: 1059 children aged 15 months to 7 years; children younger than 4 were the primary population. INTERVENTIONS: Supervised isocaloric servings (≈1300 kJ, five mornings each week, 23 weeks) of a new food supplement (NEWSUP, high in plant polyphenols and omega 3 fatty acids, within a wide variety and high fortification of micronutrients, and a high protein content), or a fortified blended food (FBF) used in nutrition programs, or a control meal (traditional rice breakfast). MAIN OUTCOME MEASUREMENTS: The primary outcome was working memory, a core executive function predicting long term academic achievement. Additional outcomes were hemoglobin concentration, growth, body composition, and index of cerebral blood flow (CBFi). In addition to an intention-to-treat analysis, a predefined per protocol analysis was conducted in children who consumed at least 75% of the supplement (820/925, 89%). The primary outcome was assessed by a multivariable Poisson model; other outcomes were assessed by multivariable linear mixed models. RESULTS: Among children younger than 4, randomization to NEWSUP increased working memory compared with the control meal (rate ratio 1.20, 95% confidence interval 1.02 to 1.41, P=0.03), with a larger effect in the per protocol population (1.25, 1.06 to 1.47, P=0.009). NEWSUP also increased hemoglobin concentration among children with anemia (adjusted mean difference 0.65 g/dL, 95% confidence interval 0.23 to 1.07, P=0.003) compared with the control meal, decreased body mass index z score gain (-0.23, -0.43 to -0.02, P=0.03), and increased lean tissue accretion (2.98 cm2, 0.04 to 5.92, P=0.046) with less fat (-5.82 cm2, -11.28 to -0.36, P=0.04) compared with FBF. Additionally, NEWSUP increased CBFi compared with the control meal and FBF in both age groups combined (1.14 mm2/s×10-8, 0.10 to 2.23, P=0.04 for both comparisons). Among children aged 4 and older, NEWSUP had no significant effect on working memory or anemia, but increased lean tissue compared with FBF (4.31 cm2, 0.34 to 8.28, P=0.03). CONCLUSIONS: Childhood undernutrition is associated with long term impairment in cognition. Contrary to current understanding, supplementary feeding for 23 weeks could improve executive function, brain health, and nutritional status in vulnerable young children living in low income countries. Further research is needed to optimize nutritional prescriptions for regenerative improvements in cognitive function, and to test effectiveness in other vulnerable groups. TRIAL REGISTRATION: ClinicalTrials.gov NCT03017209.

RESUMEN

BACKGROUND: Multiple specialized nutritious food options are programmed for supplementation in humanitarian and development settings. However, comparative cost-effectiveness evidence is lacking, let alone incorporation of perspectives from uncompensated stakeholders. A Burkina Faso trial evaluated the cost-effectiveness of Corn Soy Blend Plus w/ oil (CSB+ w/oil, reference arm), Corn Soy Whey Blend w/oil (CSWB w/oil), Super Cereal Plus (SC+), and Ready-to-Use Supplementary Food (RUSF) in reducing stunting and wasting among children 6-23 months old. This paper presents cost-effectiveness findings from multiple stakeholders' perspectives, including caregivers and program volunteers. METHODS: An activity-based costing with ingredients approach was used to summarize cost of the 18-month-long blanket supplementary feeding for each enrolled child (in 2018 USD). Time data were collected using self-reported and observational instruments. Cost-effectiveness relative to CSB+ w/oil assessed incremental cost per enrolled child against incremental outcomes: prevalence of stunting at 23 months of age and number of months of wasting. Two combined perspectives were compared: program (donor, implementer, and volunteer) versus program and caregiver (adding caregiver). RESULTS: A total of 6112 children were enrolled. While similar effectiveness was found in three arms (CSWB w/oil was less effective), costs differed. Product cost and caregiver time to prepare study foods were major drivers of cross-arm cost differences from the respective combined perspective. The two major drivers were used to construct uncertainty ranges of cost per enrolled child from program and caregiver perspective: $317 ($279- $355) in CSB+ w/oil, $350 ($327- $373) in CSWB w/oil, $387 ($371- $403) in RUSF, and $434 ($365- $503) in SC+. Cost from program and caregiver perspective was a substantial increase from program perspective. CSB+ w/oil was most cost-effective in reducing stunting and wasting, and this main finding was robust to changing perspectives and all corresponding sensitivity analyses when uncompensated time was valued at minimum wage ($0.36/h). The break-even point for uncompensated time valuation is >$0.84/h, where RUSF became the most cost-effective from the program and caregiver perspective. Relative cost-effectiveness rankings among the other three arms depended on choice of perspectives, and were sensitive to values assigned to product cost, international freight cost, opportunity cost of time, and outcomes of a hypothetical control. Volunteer opportunity cost did not affect arm comparisons, but lack of compensation resulted in negative financial consequences for caregivers. CONCLUSIONS: Evaluating cost-effectiveness by incorporating uncompensated stakeholders provided crucial implementation insights around nutrition products and programming.

RESUMEN

Improving maternal and child nutrition in resource-poor settings requires effective use of limited resources, but priority-setting is constrained by limited information about program costs and impacts, especially for interventions designed to improve diet quality. This study utilized a mixed methods approach to identify, describe and estimate the potential costs and impacts on child dietary intake of 12 nutrition-sensitive programs in Ethiopia, Nigeria and India. These potential interventions included conditional livestock and cash transfers, media and education, complementary food processing and sales, household production and food pricing programs. Components and costs of each program were identified through a novel participatory process of expert regional consultation followed by validation and calibration from literature searches and comparison with actual budgets. Impacts on child diets were determined by estimating of the magnitude of economic mechanisms for dietary change, comprehensive reviews of evaluations and effectiveness for similar programs, and demographic data on each country. Across the 12 programs, total cost per child reached (net present value, purchasing power parity adjusted) ranged very widely: from 0.58 to 2650 USD/year among five programs in Ethiopia; 2.62 to 1919 USD/year among four programs in Nigeria; and 27 to 586 USD/year among three programs in India. When impacts were assessed, the largest dietary improvements were for iron and zinc intakes from a complementary food production program in Ethiopia (increases of 17.7 mg iron/child/day and 7.4 mg zinc/child/day), vitamin A intake from a household animal and horticulture production program in Nigeria (335 RAE/child/day), and animal protein intake from a complementary food processing program in Nigeria (20.0 g/child/day). These results add substantial value to the limited literature on the costs and dietary impacts of nutrition-sensitive interventions targeting children in resource-limited settings, informing policy discussions and serving as critical inputs to future cost-effectiveness analyses focusing on disease outcomes.

RESUMEN

BACKGROUND: Existing health and nutrition services present potential platforms for scaling up delivery of early childhood development (ECD) interventions within sensitive windows across the life course, especially in the first 1000 days from conception to age 2 years. However, there is insufficient knowledge on how to optimize implementation for such strategies in an integrated manner. In light of this knowledge gap, we aimed to systematically identify a set of integrated implementation research priorities for health, nutrition and early child development within the 2015 to 2030 timeframe of the Sustainable Development Goals (SDGs). METHODS: We applied the Child Health and Nutrition Research Initiative method, and consulted a diverse group of global health experts to develop and score 57 research questions against five criteria: answerability, effectiveness, deliverability, impact, and effect on equity. These questions were ranked using a research priority score, and the average expert agreement score was calculated for each question. FINDINGS: The research priority scores ranged from 61.01 to 93.52, with a median of 82.87. The average expert agreement scores ranged from 0.50 to 0.90, with a median of 0.75. The top-ranked research question were: i) "How can interventions and packages to reduce neonatal mortality be expanded to include ECD and stimulation interventions?"; ii) "How does the integration of ECD and MNCAH&N interventions affect human resource requirements and capacity development in resource-poor settings?"; and iii) "How can integrated interventions be tailored to vulnerable refugee and migrant populations to protect against poor ECD and MNCAH&N outcomes?". Most highly-ranked research priorities varied across the life course and highlighted key aspects of scaling up coverage of integrated interventions in resource-limited settings, including: workforce and capacity development, cost-effectiveness and strategies to reduce financial barriers, and quality assessment of programs. CONCLUSIONS: Investing in ECD is critical to achieving several of the SDGs, including SDG 2 on ending all forms of malnutrition, SDG 3 on ensuring health and well-being for all, and SDG 4 on ensuring inclusive and equitable quality education and promotion of life-long learning opportunities for all. The generated research agenda is expected to drive action and investment on priority approaches to integrating ECD interventions within existing health and nutrition services.

RESUMEN

BACKGROUND: Although vitamin A supplementation reduces child mortality, it remains unclear whether dosing frequency, total dose, or duration modifies effectiveness. OBJECTIVE: Determine whether mortality effects of vitamin A vary by dosing frequency, total dose, or duration. METHODS: Meta-analysis of randomized controlled trials, identified by systematic review and expert opinion, utilizing relatively standard World Health Organization doses in children <5 years. Meta-regression evaluated whether mortality effects varied by dosing frequency, total dose, or supplementation duration. RESULTS: Identified 17 trials, including 1,180,718 children, mean (standard deviation [SD]) age 31.5 (15.4) months at baseline. Supplementation frequency ranged every 3 months-every 2 years, supplementation duration 4-60 months (mean = 15.4; SD = 12.8), and total dose 134,361-2,200,000 IU (mean = 667,132 IU; SD = 540,795). Compared with control, vitamin A reduced mortality 22% (95% confidence interval [CI] = 10-32; P = 0.002). This protective effect was not modified by increasing supplementation frequency (dose/year: relative risk [RR] = 1.02; 95% CI = 0.98-1.06; P = .22), total dose (per 200,000 IU: RR = 1.02; 95% CI = 0.97-1.06; P = .31), nor supplementation duration (per year: RR = 1.06; 95% CI = 0.97-1.15; P = 0.14). Multivariate meta-regression showed similar results. Sensitivity analyses excluding 1 controversial trial (Aswathi 2013) did not alter findings. CONCLUSION: Results confirm benefits of vitamin A supplementation in children <5 years in nations with vitamin A deficiency, without influence of frequency, total dose, or dosing duration within ranges evaluated. These findings inform design and efficiency of vitamin A supplementation policies.

RESUMEN

Corn Soy Blend (CSB) porridge is commonly prepared with oil for treatment of moderate acute malnutrition (MAM). A recent review recommended that 30 g of oil be used with 100 g of CSB to increase energy density and micronutrient absorption. This study assessed the effectiveness and cost-effectiveness of program changes aimed at achieving that target oil:CSB ratio in prepared porridge. Caregivers of children in MAM supplementary feeding programs were assigned to three groups: a control group received monthly rations of 1 L oil, 8 kg CSB in bulk, and social and behavior change communication (SBCC); intervention groups received 2.6 L oil, 8 kg CSB provided either in bulk (Group 1) or four 2-kg packages with printed messages (Group 2), and enhanced SBCC emphasizing the target oil:CSB ratio. Compared to the control, both intervention groups had higher mean added oil per 100 g CSB (18 g, p < 0.01, and 13 g, p= 0.04, higher in groups 1 and 2, respectively), and greater odds of meeting or exceeding the target ratio (28.4, p< 0.01, and 12.7, p= 0.02, in groups 1 and 2, respectively). Cost per caregiver reaching the target ratio was most favorable in Group 1 ($391 in Group 1, $527 in Group 2, and $1,666 in the control). Enhanced SBCC combined with increased oil ration resulted in increased use of oil in CSB porridge in a supplementary feeding program. Modified packaging did not improve effectiveness. However, both interventions were more cost-effective than standard programming.

RESUMEN

BACKGROUND: Moderate acute malnutrition (MAM) and severe acute malnutrition (SAM) continue to exist at unacceptably high levels. There is a renewed momentum to dramatically improve nutritional status and decrease rates of malnutrition of all kinds. Although much focus is on the first 1,000 days, the period from conception to age 2 years, in relation to growth retardation (or stunting), it is just as important to pay adequate attention to wasting as a major contributor to both morbidity and mortality. OBJECTIVE: This paper reviews what is known about effective approaches for treatment and prevention of MAM and SAM, highlights nutrition blind spots in our strategies, and identifies programmatic and research gaps that, if addressed, will enhance our understanding of the menu of cost-effective approaches to alleviate acute forms of malnutrition. METHODS: The paper synthesizes presentations from the opening session of a May 2014 International Atomic Energy Agency symposium on Moderate Acute Malnutrition held in Vienna, Austria. RESULTS: Although understanding of efficacious approaches to the treatment and prevention of MAM and SAM has recently improved, the evidence base for informed policies and programs remains limited. CONCLUSIONS: If priority evidence gaps can be urgently addressed, our understanding of the menu of cost-effective interventions to alleviate acute forms of malnutrition will be considerably enhanced and the potential for impact at global scale significantly increased.

RESUMEN

A need for improved empirical evidence for the effectiveness of interventions used in the management of child wasting (moderate and/or severe acute malnutrition) has recently been highlighted. There is no lack of published studies in this field, but when examined through the lens of systematic review protocols, few of these studies stand up to rigorous methodological critique. This paper summarizes the current state of knowledge, as supported by high-quality research included in multiple systematic reviews. It also elaborates on the criteria and standards used in such reviews. The paper highlights the weaknesses of many studies that could, with more care during study design and reporting, result in a larger body of evidence being available to policy makers and program implementers dealing with child wasting.

RESUMEN

Maternal undernutrition contributes to 800,000 neonatal deaths annually through small for gestational age births; stunting, wasting, and micronutrient deficiencies are estimated to underlie nearly 3·1 million child deaths annually. Progress has been made with many interventions implemented at scale and the evidence for effectiveness of nutrition interventions and delivery strategies has grown since The Lancet Series on Maternal and Child Undernutrition in 2008. We did a comprehensive update of interventions to address undernutrition and micronutrient deficiencies in women and children and used standard methods to assess emerging new evidence for delivery platforms. We modelled the effect on lives saved and cost of these interventions in the 34 countries that have 90% of the world's children with stunted growth. We also examined the effect of various delivery platforms and delivery options using community health workers to engage poor populations and promote behaviour change, access and uptake of interventions. Our analysis suggests the current total of deaths in children younger than 5 years can be reduced by 15% if populations can access ten evidence-based nutrition interventions at 90% coverage. Additionally, access to and uptake of iodised salt can alleviate iodine deficiency and improve health outcomes. Accelerated gains are possible and about a fifth of the existing burden of stunting can be averted using these approaches, if access is improved in this way. The estimated total additional annual cost involved for scaling up access to these ten direct nutrition interventions in the 34 focus countries is Int$9·6 billion per year. Continued investments in nutrition-specific interventions to avert maternal and child undernutrition and micronutrient deficiencies through community engagement and delivery strategies that can reach poor segments of the population at greatest risk can make a great difference. If this improved access is linked to nutrition-sensitive approaches--ie, women's empowerment, agriculture, food systems, education, employment, social protection, and safety nets--they can greatly accelerate progress in countries with the highest burden of maternal and child undernutrition and mortality.

RESUMEN

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.

RESUMEN

The global economic crisis, commodity price hikes, and climate change have worsened the position of the poorest and most vulnerable people. These crises are compromising the diet and health of up to 80% of the population in most developing countries and threaten the development of almost an entire generation of children ( approximately 250 million), because the period from conception until 24 mo of age irreversibly shapes people's health and intellectual ability. High food prices reduce diversity and nutritional quality of the diet and for many also reduce food quantity. Poor households are hit hardest, because they already spend 50-80% of expenditures on food, little on medicines, education, transport, or cooking fuel, and cannot afford to pay more. Reduced public spending, declining incomes, increased food and fuel prices, and reduced remittance thus impede and reverse progress made toward Millenium Development Goals 1, 4, and 5. Investments in nutrition are among the most cost-effective development interventions because of very high benefit:cost ratios, for individuals and for sustainable growth of countries, because they protect health, prevent disability, boost economic productivity, and save lives. To bridge the gap between nutrient requirements, particularly for groups with high needs, and the realistic dietary intake under the prevailing circumstances, the use of complementary food supplements to increase a meal's nutrient content is recommended. This can be in the form of, e.g., micronutrient powder or low-dose lipid-based nutrient supplements, which can be provided for free, in return for vouchers, at subsidized, or at commercial prices.

RESUMEN

This paper examines how nutrition has been used to raise humanitarian relief resources through the United Nations appeals process, from 1992 to early 2009. Recent calls for "nutrition safety nets" as a response to the world food price crisis reflect a growing recognition of nutrition as a key element in crisis management, not simply as a metric of how bad things have become. The evolution in thinking about the role of nutrition in emergency programming is reflected in changes in how nutrition has been conceptualized and presented in the consolidated appeals process. Based on a desk review, supported by key informant interviews, the paper highlights important changes that include an increasing distinction that separates nutrition from food, water, and health; the importance of synergies across sectors; increased emphasis on "essential packages" of inputs and services versus stand-alone activities; the importance of technical rigor in food and nutrition assessment and surveys; the need for technical competency and capacity in the design and management of nutrition interventions; and the importance of planning for long-term change even in delivering a short-term response. There has also been growing emphasis on specificity in objectives--a trend linked to demand for more accountability across the humanitarian system. Enhanced emergency preparedness will require further capacity building and improved systems for surveillance and data management. Without more systematic, targeted attention to pre-crisis malnutrition, the resources needed to tackle nutrition problems during emergencies will continue to grow.

RESUMEN

Indonesia's economic crisis of late 1990s lowered consumption of micronutrient-rich foods, which increased the prevalence of micronutrient deficiencies, including anemia. As a postcrisis response, 5 nongovernmental organizations (NGOs) implemented Food for Work (FFW) programs to protect food consumption levels and nutritional status by providing rice, sometimes combined with oil and/or pinto beans. An independent evaluation assessed the effect of the FFW programs on nutrition outcomes, particularly anemia. A quasi-experimental design was used in which 1500 beneficiary and 1500 control households were randomly selected and followed in each of 3 urban and 2 rural sites. Baseline data were collected before program implementation and subsequently at approximately 6-mo intervals for 2.5 y. The poor were found to be appropriately targeted, and program participation ranged from 4 to 18 mo. The proportion of households with debts ranged from 32 to 70%; although it was higher among beneficiaries than controls, it increased among controls, but not beneficiaries. However, only among urban poor mothers in Surabaya were the odds of anemia at endline lower when participating in the FFW program (0.60, 95%CI [0.40-0.89]). Other risk factors for anemia in mothers and children included nutritional status (anemia at baseline, low BMI, receipt of vitamin A capsule, child age) and socioeconomic status (maternal education, having official residency in the area, income level). Thus, postcrisis FFW programs had limited effect on anemia, the main identified nutritional problem. Closer attention is required to the potential for affecting nutritional outcomes through FFW, including food aid quality and quantity and complementary nonfood interventions. Micronutrient deficiencies should be addressed directly via supplements and fortified foods.

RESUMEN

Vitamin and mineral deficiencies adversely affect a third of the world's people. Consequently, a series of global goals and a serious amount of donor and national resources have been directed at such micronutrient deficiencies. Drawing on the extensive experience of the authors in a variety of institutional settings, the article used a computer search of the published scientific literature of the topic, supplemented by reports and published and unpublished work from the various agencies. In examining the effect of sex on the economic and social costs of micronutrient deficiencies, the paper found that: (1) micronutrient deficiencies affect global health outcomes; (2) micronutrient deficiencies incur substantial economic costs; (3) health and nutrition outcomes are affected by sex; (4) micronutrient deficiencies are affected by sex, but this is often culturally specific; and finally, (5) the social and economic costs of micronutrient deficiencies, with particular reference to women and female adolescents and children, are likely to be considerable but are not well quantified. Given the potential impact on reducing infant and child mortality, reducing maternal mortality, and enhancing neuro-intellectual development and growth, the right of women and children to adequate food and nutrition should more explicitly reflect their special requirements in terms of micronutrients. The positive impact of alleviating micronutrient malnutrition on physical activity, education and productivity, and hence on national economies suggests that there is also an urgent need for increased effort to demonstrate the cost of these deficiencies, as well as the benefits of addressing them, especially compared with other health and nutrition interventions.
