The aim of this study was to assess the prevalence of iron deficiency anemia\u00a0and 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\u00a0gestation. Data was collected regarding demographic and pregnancy features and hemoglobin and serum ferritin concentrations were\u00a0determined. 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\u00a0iron deficiency and 22 (10.9%) revealed severe iron depletion. Maternal age was the only risk factor identified. The odds ratio (OR) was\u00a0equal 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\u00a0years of age.Discussion and Conclusion: The prevalence of maternal anemia in the first half of pregnancy was lower than in other studies.\u00a0However, more than one-third of the women exhibited iron deficiency. With the exception of maternal age, no other risk factors were\u00a0identified.<\/jats:p>","DOI":"10.20344\/amp.6808","type":"journal-article","created":{"date-parts":[[2016,10,3]],"date-time":"2016-10-03T23:38:22Z","timestamp":1475537902000},"page":"514-518","source":"Crossref","is-referenced-by-count":24,"title":["Prevalence and Risk Factors for Iron Deficiency Anemia and Iron Depletion During Pregnancy: A Prospective Study"],"prefix":"10.20344","volume":"29","author":[{"given":"Ana","family":"Gomes da Costa","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sara","family":"Vargas","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nuno","family":"Clode","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lu\u00eds","family":"M.
