    ABSTRACT: The scaling up nutrition (SUN) policy framework requires extensive public-private partnership (PPP). Malnutrition is multi-dimensional and should engage multi-sectoral platforms. The SUN policy however did not fully embrace the dynamics of harnessing PPP. The objectives of the present paper are to highlight the reasons for the apprehension around PPP and illustrate how effective coordination of PPP in West Africa has contributed to implementing large-scale food fortification with micronutrients as a complementary nutrition intervention. The experience of Helen Keller International (HKI) in scaling up food fortification was emphasised with understanding of the factors contributing to indifference by the international community to private sector contribution to SUN. The roles of different stakeholders in a PPP are elucidated and the process linked to who, why and how to engage. The private sector provides direct nutrition services while the public sector creates the enabling environment for the private sector to thrive on social values. Through this approach fortified vegetable oil and wheat flour are now reaching over 70% of the population in West Africa. As a neutral broker HKI coordinated and facilitated dialogue among the different stakeholders. The core competencies of each stakeholder were harnessed and each partner was held accountable. It concludes that multi-sectoral relationship must be transparent, equitable and based on shared mutual interests. The rules and values of PPP offer opportunities for SUN.

    ABSTRACT: Zinc supplementation of young children in lower-income countries reduces morbidity from diarrhea and pneumonia and all-cause mortality, but the most cost-effective approach for distributing zinc supplements is unknown. To examine the potential impact of four possible strategies for delivering zinc supplements on disease prevention and deaths averted among children 6 to 59 months of age in sub-Saharan Africa. We analyzed different zinc supplementation strategies to assess their likely impact on morbidity and mortality of preschool children in sub-Saharan Africa and to estimate their possible costs. Preventive zinc supplementation reduces diarrhea incidence by 27% among children 12 to 59 months of age, pneumonia incidence by 21% among children 6 to 59 months of age, and all-cause mortality by 18% among children 12 to 59 months of age. The likely average total program costs of zinc supplementation programs were estimated from the outlays of existing service delivery platforms, such as child health days, community-based nutrition programs, and clinic-based treatment of diarrhea, assuming different levels of coverage and target age ranges of children. We found that the average total costs per life saved ranged from approximately US$462 to US$3,111, and the most cost-effective interventions were weekly or intermittent preventive zinc supplementation, because of the possibility of high coverage and fewer supplements required. Empirical data from zinc supplementation programs will be needed to confirm these estimates.

    ABSTRACT: Food fortification has been increasingly recognized as a promising approach to prevent micronutrient deficiencies. The Fortification Rapid Assessment Tool (FRAT) was developed to assist public health program managers to acquire the information needed to implement an effective mass food fortification program. Multiple countries have conducted FRAT surveys, but information on results and experiences with the FRAT tool has been available only at the national level. To summarize the findings of the FRAT surveys previously conducted in sub-Saharan Africa. Surveys from 12 sub-Saharan African countries (Burkina Faso, Cameroon, Congo, Guinea, Malawi, Mali, Mauritania, Mozambique, Niger, Rwanda, Senegal, Uganda) were identified. Information on consumption patterns for wheat flour, vegetable oil, sugar, and bouillon cubes was reviewed and summarized. Most surveys found that a moderate to high proportion of women reported consuming wheat flour (48% to 93%), vegetable oil (44% to 98%), sugar (55% to 99%), and bouillon cubes (79% to 99%) in the past 7 days, although consumption was more common and more frequent in urban areas than in rural areas. Similarly, the reported amounts consumed during the previous 24 hours were generally higher in urban settings. The FRAT instrument has been successfully used in multiple countries, and the results obtained have helped in planning national food fortification programs. However, the recommended sampling scheme may need to be reconsidered, and the guidelines should be revised to clarify important aspects of fieldworker training, implementation, data analysis and interpretation, and reporting of the results.

    ABSTRACT: Mali is endemic for all five targeted major neglected tropical diseases (NTDs). As one of the five 'fast-track' countries supported with the United States Agency for International Development (USAID) funds, Mali started to integrate the activities of existing disease-specific national control programs on these diseases in 2007. The ultimate objectives are to eliminate lymphatic filariasis, onchocerciasis and trachoma as public health problems and to reduce morbidity caused by schistosomiasis and soil-transmitted helminthiasis through regular treatment to eligible populations, and the specific objectives were to achieve 80% program coverage and 100% geographical coverage yearly. The paper reports on the implementation of the integrated mass drug administration and the lessons learned. The integrated control program was led by the Ministry of Health and coordinated by the national NTD Control Program. The drug packages were designed according to the disease endemicity in each district and delivered through various platforms to eligible populations involving the primary health care system. Treatment data were recorded and reported by the community drug distributors. After a pilot implementation of integrated drug delivery in three regions in 2007, the treatment for all five targeted NTDs was steadily scaled up to 100% geographical coverage by 2009, and program coverage has since been maintained at a high level: over 85% for lymphatic filariasis, over 90% for onchocerciasis and soil-transmitted helminthiasis, around 90% in school-age children for schistosomiasis, and 76-97% for trachoma. Around 10 million people have received one or more drug packages each year since 2009. No severe cases of adverse effects were reported. Mali has scaled up the drug treatment to national coverage through integrated drug delivery involving the primary health care system. The successes and lessons learned in Mali can be valuable assets to other countries starting up their own integrated national NTD control programs.

    ABSTRACT: Schoolchildren in Nigeria are rarely targeted by micronutrient interventions. We completed a 6-mo, double-blind, placebo-controlled trial to determine the effects of a multi-micronutrient beverage on biochemical and anthropometric indicators of nutritional status among schoolchildren participating in a pilot school feeding program in Nasarawa State, Nigeria. Children received 1 of 2 interventions 5 d/wk during school hours: 1) 250 mL/d of a multi-micronutrient beverage that included vitamin A, iron, and zinc (micronutrient); or 2) an isoenergetic control beverage (control). At baseline, 566 children 5-13 y old were randomized to groups (micronutrient: n = 288; control: n = 278). Height, weight, hemoglobin, and serum concentrations of C-reactive protein, ferritin, retinol, and zinc were measured at baseline and at the end of the study. A total of 270 children in the micronutrient group and 264 children in the control group completed the study. Self-reports of vomiting increased in both groups at 6 mo; however, the prevalence tended to be greater in the micronutrient group (21%) compared to the control group (14%) (P = 0.06). Biochemical changes were greater in the micronutrient group compared to control for serum retinol (0.10 ± 0.02 μmol/L vs. 0.02 ± 0.02 μmol/L; P = 0.016) and zinc (1.0 ± 0.2 μmol/L vs. 0.6 ± 0.2 μmol/L; P = 0.031). The intervention did not significantly affect hemoglobin or serum ferritin concentrations. The cost effectiveness of the intervention needs to be further evaluated, as does the efficacy of the beverage on anemia and indicators of iron status.

    ABSTRACT: A three-day workshop was convened in Dakar, Senegal, to provide participants from West African and international academic and research institutions, public health agencies, and donor organisations an opportunity to review current public health nutrition research and training capabilities in West Africa, assess needs for strengthening the regional institutional and workforce capacities, and discuss appropriate steps required to advance this agenda. The workshop included presentations of background papers, experiences of regional and international training programmes and small group discussions. Participants concluded that there is an urgent need to: (1) increase the throughput of public health nutrition training programmes, including undergraduate education, pre-service and in-service professional training, and higher education in public health nutrition and related research skills; and (2) enhance applied research capacity, to provide the evidence base necessary for nutrition program planning and evaluation. A Task Team was appointed to inform the regional Assembly of Health Ministers of the workshop conclusions and to develop political and financial support for a regional nutrition initiative to: (1) conduct advocacy and nutrition stewardship; (2) survey existing training programmes and assist with curriculum development; and (3) develop a plan for a regional applied research institute in Public Health Nutrition.

    ABSTRACT: Zinc supplementation trials carried out among children have produced variable results, depending on the specific outcomes considered and the initial characteristics of the children who were enrolled. We completed a series of meta-analyses to examine the impact of preventive zinc supplementation on morbidity; mortality; physical growth; biochemical indicators of zinc, iron, and copper status; and indicators of behavioral development, along with possible modifying effects of the intervention results. Zinc supplementation reduced the incidence of diarrhea by approximately 20%, but the impact was limited to studies that enrolled children with a mean initial age greater than 12 months. Among the subset of studies that enrolled children with mean initial age greater than 12 months, the relative risk of diarrhea was reduced by 27%. Zinc supplementation reduced the incidence of acute lower respiratory tract infections by approximately 15%. Zinc supplementation yielded inconsistent impacts on malaria incidence, and too few trials are currently available to allow definitive conclusions to be drawn. Zinc supplementation had a marginal 6% impact on overall child mortality, but there was an 18% reduction in deaths among zinc-supplemented children older than 12 months of age. Zinc supplementation increased linear growth and weight gain by a small, but highly significant, amount. The interventions yielded a consistent, moderately large increase in mean serum zinc concentrations, and they had no significant adverse effects on indicators of iron and copper status. There were no significant effects on children's behavioral development, although the number of available studies is relatively small. The available evidence supports the need for intervention programs to enhance zinc status to reduce child morbidity and mortality and to enhance child growth. Possible strategies for delivering preventive zinc supplements are discussed.

    ABSTRACT: This paper summarizes the results of the foregoing reviews of the impact of different intervention strategies designed to enhance zinc nutrition, including supplementation, fortification, and dietary diversification or modification. Current evidence indicates a beneficial impact of such interventions on zinc status and zinc-related functional outcomes. Preventive zinc supplementation reduces the incidence of diarrhea and acute lower respiratory tract infection among young children, decreases mortality of children over 12 months of age, and increases growth velocity. Therapeutic zinc supplementation during episodes of diarrhea reduces the duration and severity of illness. Zinc fortification increases zinc intake and total absorbed zinc, and recent studies are beginning to confirm a positive impact of zinc fortification on indicators of population zinc status. To assist with the development of zinc intervention programs, more information is needed on the prevalence of zinc deficiency in different countries, and rigorous evaluations of the effectiveness of large-scale zinc intervention programs should be planned. Recommended steps for scaling up zinc intervention programs, with or without other micronutrients, are described. In summary, there is now clear evidence of the benefit of selected interventions to reduce the risk of zinc deficiency, and a global commitment is urgently needed to conduct systematic assessments of population zinc status and to develop interventions to control zinc deficiency in the context of existing public health and nutrition programs.
