          Abstract

          OBJETIVO: determinar a prevalência e fatores de risco associados à anemia em gestantes da região semi-árida de Alagoas. MÉTODOS: estudo de caráter transversal envolvendo amostra (n=150) obtida, considerando a prevalência estimada pela Organização Mundial da Saúde de 52%, com erro de 8% e intervalo de confiança de 95%. O processo de amostragem foi realizado em três estágios: 15 dentre os 38 municípios da região, quatro setores censitários por município e 24 domicílios por setor. Nestes, eram elegíveis todas as gestantes residentes, das quais se coletaram dados socioeconômicos, demográficos, antropométricos e de saúde. A anemia foi identificada por um nível de hemoglobina <11 g/dL e sua associação com os fatores de risco foi testada por meio de análise de regressão linear múltipla. RESULTADOS: a prevalência de anemia foi de 50%. Setenta e oito por cento das gestantes estavam sob acompanhamento pré-natal. Destas, 79,3% se encontravam no segundo ou terceiro trimestre de gestação. Contudo, apenas 21,2% faziam uso de suplemento de ferro. As variáveis associadas (p<0,05) de forma independente à anemia (gestantes anêmicas versus não anêmicas) foram: maior número de membros na família (4,5±2,3 versus 4,3±2,3; p=0,02), menor faixa etária da gestante (23,9±6,3 versus 24,7±6,7; p=0,04), bem como de seu companheiro (34,5±15,8 versus 36±17,5; p=0,03), não possuir vaso sanitário em casa (30,7 versus 24%; p<0,001), história de perda de filho por abortamento e/ou mortalidade (32,4 versus 16,4%; p<0,001), residência em zona rural (60 versus 46,7%; p=0,03), renda per capita <US$1,00/dia (60,3 versus 52,1%; p=0,02), peso pré-gestacional <50 kg (33,3 versus 24,6%; p=0,03) e início do pré-natal após o primeiro trimestre de gestação (45,3 versus 18%; p=0,002). CONCLUSÕES: a prevalência de anemia em gestantes da região semi-árida de Alagoas se constitui num problema de elevada magnitude, justificando atenção prioritária por parte dos gestores das políticas públicas.

          PURPOSE: to determine the prevalence and risk factors associated to anemia in pregnant women from the semiarid region of Alagoas, Brazil. METHODS: transversal study comprising a sample (n=150) obtained taking into consideration the prevalence estimated by World Health Organization of 52%, an error of 8% and a confidence interval of 95%. Sampling has been done in three stages: 15 towns among the 38 in the region, four census sectors by town and 24 residences by sector. All the resident pregnant women were eligible, and their socio-economic, demographic, anthropometric and health data have been collected. Anemia was identified at the <11 g/dL hemoglobin level (Hemocue®), and its association with risk factors, tested by multiple linear regression analysis. RESULTS: anemia prevalence was 50%. Seventy eight per cent of the pregnant women were under pre-natal care. From those, 79.3% were in the second or third trimester of gestation. Nevertheless, only 21.2% of them were taking iron supplementation. Variables (p<0.05) independently associated with anemia (anemic versus not-anemic pregnant women) were: larger number of family members (4.5±2.3 versus 4,3±2.3; p=0.02), lower age group of the pregnant woman (23.9±6.3 versus 24.7±6.7; p=0.04), or of her partner (34.5±15.8 versus 36±17.5; p=0.03), no toilet in the house (30.7 versus 24%; p<0.001), history of child abortion and/or death (32.4 versus 16.4%; p<0.001), living in the country (60 versus 46.7%; p=0.03), average per capita income <US$1.00/day (60.3 versus 52.1%; p=0.02), pre-gestational weight <50 kg (33.3 versus 24.6%; p=0.03), pre-natal care onset after the first trimester of gestation (45.3 versus 18%; p=0.002). CONCLUSIONS: anemia prevalence in pregnant women from the semiarid region of Alagoas constitutes a major health problem, deserving special attention by the people in charge of public policy.

          Anemia and iron deficiency: effects on pregnancy outcome.

          This article reviews current knowledge of the effects of maternal anemia and iron deficiency on pregnancy outcome. A considerable amount of information remains to be learned about the benefits of maternal iron supplementation on the health and iron status of the mother and her child during pregnancy and postpartum. Current knowledge indicates that iron deficiency anemia in pregnancy is a risk factor for preterm delivery and subsequent low birth weight, and possibly for inferior neonatal health. Data are inadequate to determine the extent to which maternal anemia might contribute to maternal mortality. Even for women who enter pregnancy with reasonable iron stores, iron supplements improve iron status during pregnancy and for a considerable length of time postpartum, thus providing some protection against iron deficiency in the subsequent pregnancy. Mounting evidence indicates that maternal iron deficiency in pregnancy reduces fetal iron stores, perhaps well into the first year of life. This deserves further exploration because of the tendency of infants to develop iron deficiency anemia and because of the documented adverse consequences of this condition on infant development. The weight of evidence supports the advisability of routine iron supplementation during pregnancy.

              Iron requirements in pregnancy and strategies to meet them.

              T BOTHWELL (2000)
              Iron requirements are greater in pregnancy than in the nonpregnant state. Although iron requirements are reduced in the first trimester because of the absence of menstruation, they rise steadily thereafter; the total requirement of a 55-kg woman is approximately 1000 mg. Translated into daily needs, the requirement is approximately 0.8 mg Fe in the first trimester, between 4 and 5 mg in the second trimester, and >6 mg in the third trimester. Absorptive behavior changes accordingly: a reduction in iron absorption in the first trimester is followed by a progressive rise in absorption throughout the remainder of pregnancy. The amounts that can be absorbed from even an optimal diet, however, are less than the iron requirements in later pregnancy and a woman must enter pregnancy with iron stores of >/=300 mg if she is to meet her requirements fully. This is more than most women possess, especially in developing countries. Results of controlled studies indicate that the deficit can be met by supplementation, but inadequacies in health care delivery systems have limited the effectiveness of larger-scale interventions. Attempts to improve compliance include the use of a supplement of ferrous sulfate in a hydrocolloid matrix (gastric delivery system, or GDS) and the use of intermittent supplementation. Another approach is intermittent, preventive supplementation aimed at improving the iron status of all women of childbearing age. Like all supplementation strategies, however, this approach has the drawback of depending on delivery systems and good compliance. On a long-term basis, iron fortification offers the most cost-effective option for the future.
