 Anemia continues to be a public health problem of global proportions. Severe anemia hemoglobin, Hb 70 gL is of special concern as it poses a significant health and mortality risk. Pregnant women and young children 6-24 months of age are the two groups at highest risk. Severe anemia in pregnant women is associated with an elevated risk of maternal and perinatal mortality as well as case fatality. Pakistan, the country in which this study is ongoing, may harbor the highest prevalence of severe anemia in South Asia, with as high as 15 being reported among pregnant women. Comparable rates 11-12 are also seen among 6-24 month old children. Iron deficiency is one of the major causes of anemia in young children and pregnant women in South Asia. In addition to iron, deficiency of vitamins such as folic acid, vitamin A, vitamin C, riboflavin and vitamin E can also inhibit erythropoiesis. Apart from these nutritional causes, two other infectious causes of severe anemia are malaria and geohelminths. The current international recommendation for treatment of anemia includes iron and folic acid but not other vitamins.
