Resumo: | OBJECTIVE: Iron fortification of flour has been sanctioned by the Brazilian government since 2004. The objective of the study was to assess the impact of flour fortification on hemoglobin level in children under six. METHODS: A time-series study was carried out in Pelotas, southern Brazil, consisting of three assessments at a 12-month interval. In May 2004, before flour fortification, hemoglobin measurements were obtained in a probabilistic sample of 453 children. Twelve and 24 months later, samples of 923 and 863 children were studied, respectively. RESULTS: The three groups studied were comparable in terms of demographic and socioeconomic characteristics. At baseline, mean hemoglobin was 11.3±2.8 g/dL. In the post-fortification period, means were 11.2±2.8 (at 12 months) and 11.3±2.5 g/dL (at 24 months), with no statistically significant difference among the three time periods studied (p=0.16). CONCLUSIONS: Fortification had no effect on hemoglobin levels of the children studied. This finding could be partially due to inadequate flour intake and/or low bioavailability of dietary iron. |

OBJETIVO: A fortificação de farinhas com ferro foi estabelecida por lei no Brasil, em 2004. O objetivo do estudo foi avaliar o impacto da fortificação sobre nível de hemoglobina em crianças menores de seis anos. MÉTODOS: O estudo foi realizado em Pelotas, RS, sendo uma série temporal com três avaliações a cada 12 meses. Em maio de 2004, antes da fortificação das farinhas, foram medidos níveis de hemoglobina em amostra probabilística de 453 crianças. Após 12 e 24 meses, foram estudadas amostras de 923 e 863 crianças, respectivamente. RESULTADOS: Os três grupos estudados foram comparáveis em relação a características demográficas e socioeconômicas. No estudo de linha de base, as médias de hemoglobina foram 11,3±2,8 g/dL. Após a fortificação esses valores foram 11,2±2,8 (12 meses) e 11,3±2,5 g/dL (24 meses), não havendo diferença estatisticamente significativa entre os três momentos estudados (p=0,16). CONCLUSÕES: Nenhum efeito da fortificação foi observado nos níveis de hemoglobina das crianças estudadas, o que pode ser parcialmente explicado pelo consumo insuficiente de farinhas e/ou pela baixa biodisponibilidade do ferro adicionado.
