After becoming pregnant they were evaluated every 4 weeks starting in the 8th week of pregnancy until 1 month post-partum. Every evaluation included determination of hemoglobin, ferritin and erythrocyte folate. &lt;i&gt;Results:&lt;\/i&gt; When the women started gestation with an insufficient iron store (&lt;20 \u00b5g\/l), the trend was to present anemia at significantly earlier gestational ages, in such a way that at week 20 of gestation almost 60% of the women with an inadequate store had anemia and only 25% of the women with an adequate store had this condition. On the other hand, the pregestational erythrocyte folate did not predict anemia incidence. &lt;i&gt;Conclusions:&lt;\/i&gt; Pregestational ferritin concentration predicts value of incidence of anemia throughout pregnancy.<\/jats:p>","DOI":"10.1159\/000069276","type":"journal-article","created":{"date-parts":[[2003,4,15]],"date-time":"2003-04-15T12:11:24Z","timestamp":1050408684000},"page":"60-63","source":"Crossref","is-referenced-by-count":27,"title":["Iron and Folate Status before Pregnancy and Anemia during Pregnancy"],"prefix":"10.1159","volume":"47","author":[{"given":"Esther","family":"Casanueva","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Frania","family":"Pfeffer","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alejandra","family":"Drijanski","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ana Cecilia","family":"Fern\u00e1ndez-Gaxiola","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ver\u00f3nica","family":"Guti\u00e9rrez-Valenzuela","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Stephen J.","family":"Rothenberg","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"127","published-online":{"date-parts":[[2003,3,27]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","DOI":"10.1016\/0271-5317(96)00136-4"}],"container-title":["Annals of Nutrition and Metabolism"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/69276","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/69276","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,4,24]],"date-time":"2025-04-24T03:43:22Z","timestamp":1745466202000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000069276"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2003]]},"references-count":1,"journal-issue":{"issue":"2","published-online":{"date-parts":[[2003,4,1]]}},"URL":"https:\/\/doi.org\/10.1159\/000069276","archive":["Portico"],"relation":{},"ISSN":["0250-6807","1421-9697"],"issn-type":[{"value":"0250-6807","type":"print"},{"value":"1421-9697","type":"electronic"}],"subject":[],"published":{"date-parts":[[2003]]}}}
