Abstract in Portuguese
A anemia ferropriva é a deficiência nutricional com maior prevalência em todo o mundo, principalmente nos países em desenvolvimento, constituindo um sério problema de saúde pública no nosso país. Um dos grupos vulneráveis a essa deficiência, são as crianças, devido às necessidades elevadas de ferro impostas pelo crescimento que não são supridas em razão da alimentação pobre no mineral e de baixa biodisponibilidade marcial. Dentre as conseqüências da deficiência do mineral, destaca-se a diminuição da capacidade cognitiva, que constitui importante fator de exclusão social. Urna estratégia para corrigir e/ou prevenir a deficiência nutricional, é a fortificação de alimentos básicos na dieta habitual. Assim, o objetivo deste estudo foi o de avaliar o efeito de um desses produtos, o arroz, acrescido de ferro, no controle da anemia ferropriva. O estudo de intervenção foi desenvolvido entre crianças em idade pré-escolar que freqüentavam duas creches assistenciais de São Paulo. A ocorrência de anemia foi avaliada pela concentração de hemoglobina medida através do colorímetro de leitura direta HemoCue, antes e após 3 meses da utilização do arroz enriquecido com ferro bisglicina quelato na quantidade de 2,1 mg de ferro/l00g de arroz cozido. A quantidade média per capita consumida de 60g de arroz veiculou 1,3mg de ferro adicional, valor que corresponde a 11,8% e 18,6% da IDR - Ingestão Diária Recomendada, para lactentes e crianças· de 12 a 36 meses de idade, respectivamente e foram atendidos 22% da necessidade diária do mineral ao pré-escolar. Concluiu-se que houve urna evolução estatisticamente significante na concentração de hemoglobina da população estudada de 0,5g/dL e de 1,0g/dL, entre os anêmicos. A proporção de anêmicos, considerando Hb= 11,0g/dL como valor crítico, declinou de 40,6% para 25,0%.

Abstract in English
Iron-deficiency anemia 1s the nutritional disorder with the greatest prevalence worldwide. This is especially the case in developing countries, and is a serious public health problem in Brazil Children are one of the groups most susceptible to this deficiency, due to the high levels of iron required by the growth process. These needs are often not met by the children's diets, which lack mineral and martial bioavailability. Among the consequences of such deficiency, the one most worthy of note is the reduction of cognitive ability, an important factor for social exclusion. A strategy aimed at the correction and/or prevention of nutritional deficiency is the fortification of staple foods. Thus, the objective of the present study is to evaluate the effect of one of these foods, iron-fortified rice, on the control of iron-deficiency anemia. The study of this intervention was carried out among preschool children, who attended two welfare daycare centers in São Paulo, Brazil. The presence of anemia was evaluated based on measured hemoglobin concentration, using HemoCue direct reading colorimeters, prior to, and three months after, the use of iron-bisglycine chelate fortified rice at 2,1mg iron/l00g cooked rice. The 60g mean per capita rice intake provided an additional 1,3mg iron, a value corresponding to 11,8% and 18,6% of the DRI - Dietary Recommended Intakes - for infants and children between 12 and 36 months, respectively, and to 22% of the daily requirement for preschool children. The study pointed towards a statistically significant evolution in hemoglobin concentration among the population studied (0,5g/dL and 1,0g/dL among anemic children). The proportion of anemic children, assuming a critical value of Hb=11,0g/dL, declined from 40,6% to 25,0%.
