In West Africa, national, cross-sectional, household-based demographic health surveys were used to map the distribution of anemia risk in preschool-age children.The use of such maps has significant practical implications for targeted control of anemia in these countries, such as guiding the efficient allocation of nutrient supplements and fortified foods, and contributing to the planning and evaluation of resource requirements for geographical delivery of transfusion services for severe anaemia cases.
The authors say: "The development of maps indicating the geographical risk profile of anaemia controlling for malnutrition and major infections would allow assessment of the risk of anaemia due to different causes, which would in turn constitute an important evidence base to work out the best balance between interventions."
