RESUMO
OBJECTIVE: To verify the behavior of hemoglobin levels and anemia prevalence in full term infants, aged 3 to 6 months and on exclusive breastfeeding. METHODS: A cross-sectional study of 242 infants aged 3 to 6 months with birth weights of more than 2,500 g, on exclusive breastfeeding and monitored by the Program for the Promotion of Infant Growth and Development, part of the Paraisópolis Einstein Community Program. Hemoglobin was assayed by finger prick between the third and sixth months of life. Anemia was defined as Hb < 10.3 g/dL (Saarinen) or Hb < 10 g/dL (Brault-Dubuc) for infants aged 3 to 5 months and as Hb < 11.0 g/dL (WHO) for infants aged 6 months. RESULTS: Mean hemoglobin concentration was 11.3 and 11.4 g/dL at 3 and 4 months and 11.2 and 11.1 g/dL at 5 and 6 months, respectively. The percentage of anemic infants varied depending on age and the cutoff adopted, being 11.8, 10.2 and 8.3% at 3, 4 and 5 months, respectively, according to the Brault-Dubuc criteria, and 20.6, 14.8 and 10.4% by the Saarinen criteria. Anemia prevalence at 6 months was 37.5%. CONCLUSIONS: Anemia prevalence rates observed among infants aged between 3 and 6 months varied from 8.3 to 37.5%, justifying increased attention on the part of pediatricians to the hemoglobin levels of infants who are on exclusive breastfeeding, come from low-income families and present risk factors for iron deficiency.

OBJETIVO:Verificar o comportamento dos valores da hemoglobina e a prevalência de anemia entre lactentes de termo de 3 a 6 meses de idade em aleitamento materno exclusivo. MÉTODOS: Estudo transversal em 242 lactentes de 3 a 6 meses de idade com peso de nascimento superior a 2.500 g, em aleitamento materno exclusivo e em acompanhamento no Programa de Promoção do Crescimento e Desenvolvimento do Lactente do Programa Einstein na Comunidade de Paraisópolis. A dosagem de hemoglobina foi realizada por meio de punção digital entre o terceiro e o sexto meses de vida. Adotaram-se os valores de Hb < 10,3 g/dL (Saarinen) e Hb < 10 g/dL (Brault-Dubuc) como critério de anemia nas idades de 3 a 5 meses e Hb < 11,0 g/dL (OMS) para os lactentes de 6 meses. RESULTADOS: A media da hemoglobina foi de 11,3 e 11,4 g/dL aos 3 e 4 meses, 11,2 e 11,1 g/dL aos 5 e 6 meses, respectivamente. A porcentagem de anêmicos variou conforme a idade e o padrão adotado, sendo de 11,8, 10,2 e 8,3 por cento aos 3, 4 e 5 meses, segundo o critério adotado por Brault-Dubuc, e de 20,6, 14,8 e 10,4 por cento, respectivamente, para o critério de Saarinen. Aos 6 meses, a prevalência de anemia foi de 37,5 por cento. CONCLUSÕES: Observaram-se prevalências de anemia variando entre 8,3 e 37,5 por cento nos lactentes do terceiro ao sexto mês de vida, que justificam maior atenção do pediatra em relação aos níveis de hemoglobina em lactentes em aleitamento materno exclusivo, que pertençam a famílias de baixa renda e que apresentem fatores de risco para deficiência de ferro.
