چکیده

A anemia é um problema muito comum entre as crianças brasileiras1. Assim, não surpreende que a incidência de deficiência de ferro e anemia por deficiência de ferro seja consideravelmente elevada em lactentes nascidos em um hospital no estado do Rio Grande do Sul entre os 12 e os 16 meses de idade. Dos 369 lactentes que tiveram seus níveis de hemoglobina sérica mensurados no relato de Bortolini & Vitolo publicado neste número da revista, 64% eram anêmicos (hemoglobina < 11 g/dL)2. Dos 289 lactentes que tiveram seus níveis de ferritina sérica mensurados, 90% apresentaram deficiência de ferro, definida como um valor de ferritina sérica < 15 μg/L (84% tinham um valor de ferritina sérica < 12 μg/L). No grupo dos 289 lactentes, 170 (58%) também eram anêmicos, e dessa forma, foram definidos como portadores de anemia por deficiência de ferro. Por esse motivo, os pesquisadores estavam muito esperançosos quando elaboraram um ensaio clinico de intervenção para causar um impacto sobre o problema da deficiência de ferro que existia naquele local. A intervenção consistiu em um programa intensivo de orientação dietética durante o primeiro ano de vida que promoveu o aleitamento materno exclusivo nos primeiros 6 meses e enfatizou a ingestão de alimentos complementares contendo ferro nos últimos 6 meses. Os lactentes receberam uma quantidade muito pequena de fórmula fortificada com ferro e não foram recomendados suplementos para aumentar a ingestão de ferro. Infelizmente, a intervenção não teve impacto nas reservas de ferro dos lactentes, embora tivesse aumentado a duração do aleitamento materno e melhorado a qualidade dos alimentos complementares, o que por si só já é resultado significativamente positivo.
