Global Micronutrient Deficiency Estimates
For decades, the number of people world wide experiencing micronutrient deficiencies has been estimated at 2 billion. The methods used to arrive at this estimate are unclear and the data are now outdated. USAID Advancing Nutrition, in collaboration with consortium partner GAIN, and an advisory panel of experts managed by the Micronutrient Forum, is working to revise this estimate of micronutrient deficiencies and provide a transparent methodology for updating the estimate as needed. The project will use existing biomarker data from nationally representative surveys to estimate the number of women ages 15–49 and children under five who experience deficiency of at least one micronutrient.
USAID Advancing Nutrition’s HEME working group has developed a protocol for understanding how, in a laboratory setting, the blood specimen (single drop vs. pooled capillary) and devices (various models of the HemoCue) affect hemoglobin measurement. Known as the HEmoglobin MEasurement (HEME) laboratory validation study, the project will award grants to conduct the study in different settings around the world. Once finalized, the project will synthesize the results for dissemination. With the assistance of the USAID Advancing Nutrition Anemia Task Force, we will add global context to the study findings.
Anemia Measurement, Assessment, and Interventions
The USAID Advancing Nutrition Anemia Task Force (ATF), a panel of anemia experts, is developing a comprehensive overview of anemia: what has been done, what we are uncovering now, and what we can do to reach the World Health Assembly goals for reducing anemia. The ATF will adopt an ecological approach that includes an appreciation of systems biology: understanding the biological mechanisms underpinning various causes of anemia, translation of knowledge of biology within sensitive and specific assessment methodologies and interventions, which ultimately improve clinical and public health outcomes.

Food Fortification and Supplementation
USAID Advancing Nutrition is building on evidence generated through USAID investments in Uganda’s fortification and supplementation programs by publishing findings that show that mandatory fortification of maize flour, most of which is produced by small-scale producers, is financially unsustainable. These findings are based on two notable investments in implementation research—one on micronutrient powder (MNP) supplementation, and the other on small-scale maize flour fortification—that are key to current policy discussions in Uganda. In the first investment, the USAID-funded SPRING project collaborated with the Ministry of Health in Uganda to pilot a district-wide distribution of MNP to all children ages 6 to 23 months in Namutumba District. The pilot provided MNP from February to November 2016 to health facilities and households through outreach programs. Although SPRING collected data on the costs of distributing through these two channels, the data have not been published. In the second instance, the SPRING project conducted a cost analysis of small-scale maize flour fortification in Uganda in partnership with the MOH and the Ministry of Trade Industry and Cooperatives.
