In developed countries, about 20% of the gestantes they present anemia during the pregnancy. Already in the developing countries, this index increases significantly, varying around 35% 75% (WHO, 2005). More specifically, the anemia in the gestatrio cycle, especially for iron lack, can be associated the increase of mortality materna, perinatal mortality, prematurity, low weight to the rising and morbidade of the infant. Forty percent of all the perinatais deaths maternas are on to anemia (SCHOLL; REILLY, 2000; WHO, 2001; RASMUSSEN, 2001). Parallel, a favorable outcome of the pregnancy occurs 30 less 40% in anmicas, and its conceptos have less of the half of the normal reserve of iron, being able to present greater frequency of anemia in the first year of life (WHO; 2001). Therefore, the anmicas gestantes must be dealt with immediately through the modification the alimentary habits, food blockhouse and medicamentosa suplementao with you leave iron (UNICEF, 1998; WHO, 2001; BEINNER; LAMOUNIER; TOMAZ, 2005). 4.
CAUSES OF the ANEMIA In accordance with Oliveira (2007), the anemias can occur for diverse etiolgicos factors. However, the anemias lacks (deficiency of iron, B12 vitamin and folatos) if detach as most common, after the anemias for sanguineous loss. Del Giglio (2007), affirms that the cause of ferropriva anemia still occurs for loss of chronic blood due to spoliation of the iron of the mother in the period of the pregnancy/lactation and also due to me the poor absorption and diets in iron. 5. PREVALNCIA the necessary and accurate information on cases of anemia in Brazil still are few, exist studies carried through in some regions that take in them to infer a prevalence of ferropriva anemia enter 22% 45% (PAHO/WHO, 1994). 6. ALTERATIONS HEMATOLGICAS IN the PREGNANCY Increase of the plasmtico volume in 45 50%. Eritrocitrio increase in 25 35% Reduction of the srico Faith Capacity of setting of Iron it is increased in 15% of gestantes 7.
