Women with inherited bleeding disorders are at increased risk, with scarce data on rates of IDA screening and correction during pregnancy. The impact of correction on outcomes is unclear. To assess the frequency of IDA screening, the frequency of IDA in pregnancies with and without bleeding disorders and the impact of correction on outcomes. This retrospective population\u2010based cohort study includes all hospitalized pregnancies using the Alberta Pregnancy Birth Cohort. IDA was defined as haemoglobin &lt;110\u2009g\/L in first\/third trimester, &lt;105\u2009g\/L in second trimester and ferritin &lt;30\u2009\u03bcg\/L. Logistic regression was performed to assess the association between IDA, corrected IDA and pregnancy outcomes. 36\u2009500\/207\u2009355 (18%) pregnancies and 14\/58 (24%) pregnancies in the bleeding disorder subgroup had anaemia. Only one of three pregnancies with anaemia had a concurrent ferritin test, and over 80% demonstrated IDA. Ferritin screening was performed in 60% of the overall cohort and 79% in bleeding disorders. Young maternal age, multiparity, lower socioeconomic status and mothers from African and Asian countries significantly predict IDA. Despite the increased risk for adverse outcomes, only 43 (8%) first\u2010trimester and 96 (9%) third\u2010trimester IDA were corrected. IDA screening and correction remained suboptimal among pregnant women. Updated screening guidelines may promote better identification and outcomes.<\/jats:p>","DOI":"10.1111\/bjh.70348","type":"journal-article","created":{"date-parts":[[2026,1,27]],"date-time":"2026-01-27T12:04:32Z","timestamp":1769515472000},"page":"1389-1397","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Suboptimal screening and correction of maternal iron deficiency anaemia in the general population and in inherited bleeding disorders: A population\u2010based cohort study"],"prefix":"10.1111","volume":"208","author":[{"given":"Arafat Ul","family":"Alam","sequence":"first","affiliation":[{"name":"Cancer Epidemiology and Prevention Research Alberta Health Services  Calgary Alberta Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Padma","family":"Kaul","sequence":"additional","affiliation":[{"name":"Department of Gynecology and Obstetrics University of Alberta  Edmonton Alberta Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Venu","family":"Jain","sequence":"additional","affiliation":[{"name":"Division of Hematology, Department of Medicine University of Alberta  Edmonton Alberta Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Cynthia","family":"Wu","sequence":"additional","affiliation":[{"name":"Department of Medicine University of Alberta  Edmonton Alberta Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Haowei (Linda)","family":"Sun","sequence":"additional","affiliation":[{"name":"Department of Medicine University of Alberta  Edmonton Alberta Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2026,1,27]]},"reference":[{"key":"e_1_2_10_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/S2214-109X(22)00084-5"},{"key":"e_1_2_10_3_1","doi-asserted-by":"publisher","DOI":"10.3390\/nu8110693"},{"key":"e_1_2_10_4_1","doi-asserted-by":"publisher","DOI":"10.1007\/978-3-031-92033-2_21"},{"key":"e_1_2_10_5_1","doi-asserted-by":"publisher","DOI":"10.1111\/trf.13252"},{"key":"e_1_2_10_6_1","doi-asserted-by":"publisher","DOI":"10.1001\/jamapsychiatry.2019.2309"},{"key":"e_1_2_10_7_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jpeds.2016.05.011"},{"key":"e_1_2_10_8_1","doi-asserted-by":"publisher","DOI":"10.1097\/AOG.0000000000003557"},{"key":"e_1_2_10_9_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1538-7836.2007.02563.x"},{"key":"e_1_2_10_10_1","doi-asserted-by":"publisher","DOI":"10.1111\/hae.14594"},{"key":"e_1_2_10_11_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ajog.2009.04.024"},{"key":"e_1_2_10_12_1","doi-asserted-by":"publisher","DOI":"10.1111\/hae.13292"},{"key":"e_1_2_10_13_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.rpth.2024.102567"},{"key":"e_1_2_10_14_1","doi-asserted-by":"publisher","DOI":"10.1182\/bloodadvances.2021004352"},{"key":"e_1_2_10_15_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jogc.2016.01.001"},{"key":"e_1_2_10_16_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jpeds.2015.06.007"},{"key":"e_1_2_10_17_1","doi-asserted-by":"publisher","DOI":"10.1007\/s41669-017-0061-0"},{"key":"e_1_2_10_18_1","doi-asserted-by":"publisher","DOI":"10.24095\/hpcdp.29.4.05"},{"key":"e_1_2_10_19_1","doi-asserted-by":"publisher","DOI":"10.1186\/s12889-015-1992-y"},{"key":"e_1_2_10_20_1","doi-asserted-by":"publisher","DOI":"10.1111\/hae.14922"},{"key":"e_1_2_10_21_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.thromres.2021.05.013"},{"key":"e_1_2_10_22_1","unstructured":"World Health Organization.WHO recommendations on antenatal care for a positive pregnancy experience.2016."},{"key":"e_1_2_10_23_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1365-2141.2011.09012.x"},{"key":"e_1_2_10_24_1","unstructured":"World Health Organization.Maternal deaths [Internet].2022World Health Organization.
