Resumo: | Introduction: Anemia and iron deficiency during pregnancy are a worldwide concern and are more frequent among women of reproductive age, pregnant women, and young children. The aim of this study was to assess the prevalence of iron deficiency anemia and the risk factors for iron depletion during the first half of pregnancy, in a Portuguese population.Material and Methods: A prospective study was conducted at a tertiary hospital and included pregnant women, until the 20th week of gestation. Data was collected regarding demographic and pregnancy features and hemoglobin and serum ferritin concentrations were determined. A multivariate logistic regression was performed to identify potential risk factors for iron deficiency.Results: Two hundred and one women were included, from which five (2.49%) presented anemia. Additionally, 77 (38.3%) exhibited iron deficiency and 22 (10.9%) revealed severe iron depletion. Maternal age was the only risk factor identified. The odds ratio (OR) was equal to 12.99 (95% CI 2.41 - 70.0) for women under twenty years of age and 2.09 (95% CI 1.05 - 4.14) for women older than thirty years of age.Discussion and Conclusion: The prevalence of maternal anemia in the first half of pregnancy was lower than in other studies. However, more than one-third of the women exhibited iron deficiency. With the exception of maternal age, no other risk factors were identified. |

O objetivo deste trabalho consistiu na avaliação da prevalência de anemia ferropénica e dos fatores de riscoassociados à ferropénia, na primeira metade da gravidez, numa amostra da população portuguesa.Material e Métodos: Estudo prospetivo, conduzido num hospital terciário, que incluiu grávidas até à 20ª semana de gestação. Foramcoletados dados demográficos, relativos à gravidez e foram determinados os níveis séricos de hemoglobina e de ferritina no sangue materno. Recorreu-se à análise de regressão logística de variáveis múltiplas para identificar potenciais fatores de risco para ferropénia.Resultados: Foram incluídas 201 grávidas, das quais cinco (2,49%) tinham anemia. Para além disso, 77 grávidas (38,3%) tinham carência de ferro e 22 (10,9%) apresentaram ferropénia grave. A idade materna foi o único fator de risco identificado. O odds ratio foi de 12,99 (95% IC 2,41 - 70,0) para grávidas com idade inferior a 20 anos e de 2,09 (95% IC 1,05 - 4,14), para grávidas com idade superior a 30 anos.Discussão e Conclusão: Na nossa amostra, a prevalência de anemia na primeira metade da gravidez foi inferior à reportada noutros estudos. No entanto, mais de 30% das grávidas apresentaram carência de ferro. A idade materna foi o único fator de risco identificado.Ordem dos Médicos2016-09-30info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfapplication/mswordapplication/mswordapplication/mswordapplication/mswordapplication/pdfhttps://www.actamedicaportuguesa.com/revista/index.php/amp/article/view/6808oai:ojs.www.actamedicaportuguesa.com:article/6808Acta Médica Portuguesa; Vol. 29 No. 9 (2016): September; 514-518Acta Médica Portuguesa; Vol. 29 N.º 9 (2016): Setembro; 514-5181646-07580870-399Xreponame:Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos)instname:Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãoinstacron:RCAAPenghttps://www.actamedicaportuguesa.com/revista/index.php/amp/article/view/6808https://www.actamedicaportuguesa.com/revista/index.php/amp/article/view/6808/4760https://www.actamedicaportuguesa.com/revista/index.php/amp/article/view/6808/7994https://www.actamedicaportuguesa.com/revista/index.php/amp/article/view/6808/7995https://www.actamedicaportuguesa.com/revista/index.php/amp/article/view/6808/7996https://www.actamedicaportuguesa.com/revista/index.php/amp/article/view/6808/7997https://www.actamedicaportuguesa.com/revista/index.php/amp/article/view/6808/8725Direitos de Autor (c) 2016 Acta Médica Portuguesainfo:eu-repo/semantics/openAccessGomes da Costa, AnaVargas, SaraClode, NunoM.
