An update on anemia in less developed countries

Abstract

The highest prevalence of anemia exists in the developing world where its causes are multi-factorial. Anemia is responsible for significant morbidity and mortality, particularly in less developed countries (LDCs). Understanding causes of anemia and potential mechanisms are crucial to our ability to intervene to reduce this burden. In the past decade, our understanding of the etiology and mechanisms of anemia in LDCs has advanced significantly. This review will focus on recent advances in our understanding of the burden of anemia in specific sub-groups, the causes and mechanisms of anemia, and consequences of anemia for the human host.
