Resumo: Iron deficiency anemia afflicts an estimated two billion people and iron deficiency approximately 4 billion people in developed countries and is even more common in developing countries. In Brazil, depending on the region and age, studies point to high prevalences of iron-deficiency anemia in children. The high growth speed, which requires a greater amount of iron, connected with an inadequate iron diet and early weaning contribute to the high prevalence, mainly within the first 2 years of life. Other risk factors, such as prematurity, low birth weight, early umbilical cord clamping and weaning from exclusive breastfeeding may contribute. The impact of iron deficiency on growth is controversial as several other variables contribute to improve or worsen the nutritional status. Alterations in the psychomotor and neural-cognitive development of infants with iron deficiency have been reported in various studies with the catch-up growth rate after treatment being controversial. Additionally, some studies have demonstrated a decrease in the intellectual development and cognitive acquisition in school age children and adolescents that is reverted after iron therapy. The best preventive measure is nutritional education, however due to the high prevalence of iron deficiency anemia, other measures should also be used as iron supplementation and food fortification with iron.

No Brasil, estudos apontam elevada prevalência de anemia ferropriva em crianças dependendo da região e da faixa etária. A velocidade de crescimento aumentada, determinando maior necessidade de ferro, aliada a dieta inadequada em ferro e ao desmame precoce, contribuem para a elevada prevalência de anemia, principalmente nos dois primeiros anos de vida. Outros fatores de risco são apontados, como a prematuridade, o baixo peso ao nascer, a ligadura precoce do cordão umbilical e o abandono do aleitamento materno exclusivo. O impacto da deficiência de ferro no crescimento permanece controverso, uma vez que inúmeras outras variáveis poderiam contribuir para melhora ou piora do estado nutricional. Alterações no desenvolvimento psicomotor e neurocognitivo, nos lactentes deficientes com ferro, têm sido relatadas em diversos estudos, sendo controversa a recuperação após o tratamento. Há trabalhos que demonstram queda no rendimento intelectual e nas aquisições cognitivas também no período escolar e adolescência, com reversão após a terapia marcial. Entre as medidas preventivas, a educação nutricional é a forma ideal; entretanto, frente à elevada prevalência, outras formas de prevenção devem ser também utilizadas, como a suplementação com ferro e a fortificação de alimentos com ferro.Universidade Federal de São Paulo (UNIFESP) EPM Departamento de PediatriaUniversidade Federal de São Paulo (UNIFESP) EPM Depto. de PediatraUNIFESP, EPM, Depto. de PediatriaUNIFESP, EPM, Depto. de PediatraSciELOAssociação Brasileira de Hematologia e Hemoterapia e Terapia CelularUniversidade Federal de São Paulo (UNIFESP)Braga, Josefina Aparecida Pellegrini [UNIFESP]Vitalle, Maria Sylvia de Souza [UNIFESP]2015-06-14T13:41:41Z2015-06-14T13:41:41Z2010-06-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersion38-44application/pdfhttp://dx.doi.org/10.1590/S1516-84842010005000054Revista Brasileira de Hematologia e Hemoterapia.
