Iron deficiency explain most of the anemia prevalence in this
population and other populations [1,7,11,28e32], so to reduce the
prevalence of anemia in childhood iron should be given [33]. Our
findings do not argue for widespread folic acid and vitamin B12
supplementation to combat anemia. Folic acid is often given with
iron to treat or prevent anemia in young children. However, the
role of these nutrients in anemia, particularly optimal dose and duration of iron supplementation should be a prioritized research
question
