Blood donation is not without risk to the donor. It results in a substantial loss of iron and decreased hemoglobin. In our country, no predonation assessment is carried out and the selection of blood donors is only clinical. Objectives. To determine the prevalence of iron deficiency, anemia, and iron deficiency anemia and to identify the factors associated with anemia and iron status in a blood donor population at the National Center for Blood Transfusion (NCBT). Methodology. A prospective study is carried out that consists of 120 blood donors in three NCBT branches in the capital from June to November 2021. The donors were divided into 3 groups: first time donors (FTDs), occasional donors (ODs) who have already made between 1 and 3 previous donations, and regular donors (RDs) with at least 4 previous donations. Iron deficiency was defined by a serum ferritin value of less than 30\u2009ng\/mL in men and 20\u2009ng\/mL in women. Anemia was defined by Hb levels below 13\u2009g\/dL in men and 12\u2009g\/dL in women. Iron deficiency anemia was defined by association of anemia and iron deficiency. The chi-square test was used for the comparison of the proportions. The odds ratio with the 95% confidence interval was calculated to assess the association between two variables. The <jats:inline-formula>\n                     <a:math xmlns:a=\"http:\/\/www.w3.org\/1998\/Math\/MathML\" id=\"M1\">\n                        <a:mi>p<\/a:mi>\n                     <\/a:math>\n                  <\/jats:inline-formula> value of the probability was considered significant for a value\u2009&lt;\u20090.05. Results. Mean serum ferritin and hemoglobin values were lower in RD in both sexes. The prevalence of iron deficiency, anemia, and iron deficiency anemia were 16.66%, 31.66%, and 10.83%, respectively. The factors associated with the three abnormalities were female sex, donor type, including RD, and number of previous donations. Conclusion. Iron deficiency, anemia, and iron deficiency anemia are common among blood donors in Brazzaville. Anemia affects almost a third of blood donors and is not always linked to iron deficiency. Safety of donors should be improved by systematic measurement of ferritinemia and hemoglobin levels before allowing donations for appropriate management in the event of abnormalities.<\/jats:p>","DOI":"10.1155\/2023\/8827984","type":"journal-article","created":{"date-parts":[[2023,12,13]],"date-time":"2023-12-13T22:20:07Z","timestamp":1702506007000},"page":"1-6","source":"Crossref","is-referenced-by-count":5,"title":["Prevalence of Iron Deficiency, Anemia, and Associated Factors in a Blood Donor Population in Brazzaville, Congo"],"prefix":"10.1155","volume":"2023","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4444-7547","authenticated-orcid":true,"given":"Firmine Olivia","family":"Galiba Atipo-Tsiba","sequence":"first","affiliation":[{"name":"Hematology Department, Teaching Hospital of Brazzaville, Brazzaville, Congo"},{"name":"Faculty of Health Sciences, Marien Ngouabi University, Brazzaville, Congo"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0008-1819-3652","authenticated-orcid":true,"given":"Earl Quincy","family":"Gayaba Mouyabi","sequence":"additional","affiliation":[{"name":"National Center for Blood Transfusion, Brazzaville, Congo"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0556-9197","authenticated-orcid":true,"given":"Brunel Monic","family":"Angounda","sequence":"additional","affiliation":[{"name":"Faculty of Health Sciences, Marien Ngouabi University, Brazzaville, Congo"},{"name":"National Center for Blood Transfusion, Brazzaville, Congo"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0001-7507-3656","authenticated-orcid":true,"given":"Serge Oscar","family":"Mokono","sequence":"additional","affiliation":[{"name":"Faculty of Health Sciences, Marien Ngouabi University, Brazzaville, Congo"},{"name":"National Center for Blood Transfusion, Brazzaville, Congo"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9006-5980","authenticated-orcid":true,"given":"Lethso Thibaut","family":"Ocko Gokaba","sequence":"additional","affiliation":[{"name":"Faculty of Health Sciences, Marien Ngouabi University, Brazzaville, Congo"},{"name":"Laboratory of Hematology, Teaching Hospital of Brazzaville, Congo"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2819-6872","authenticated-orcid":true,"given":"Alexis","family":"Elira Dokekias","sequence":"additional","affiliation":[{"name":"Hematology Department, Teaching Hospital of Brazzaville, Brazzaville, Congo"},{"name":"Faculty of Health Sciences, Marien Ngouabi University, Brazzaville, Congo"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","reference":[{"key":"1","article-title":"Dons du sang et s\u00e9curit\u00e9 des transfusions","author":"World Health Organization (WHO)","year":"2023"},{"key":"2","doi-asserted-by":"publisher","DOI":"10.2147\/jbm.s375945"},{"key":"3","doi-asserted-by":"publisher","DOI":"10.2450\/2010.0040-10"},{"key":"4","doi-asserted-by":"publisher","DOI":"10.2450\/2016.0101-16"},{"key":"5","doi-asserted-by":"publisher","DOI":"10.1016\/j.tracli.2017.06.336"},{"key":"6","doi-asserted-by":"publisher","DOI":"10.1016\/j.tracli.2019.06.296"},{"key":"7","doi-asserted-by":"publisher","DOI":"10.1016\/j.tracli.2015.06.173"},{"key":"8","doi-asserted-by":"publisher","DOI":"10.11604\/pamj.2016.23.174.7662"},{"key":"9","doi-asserted-by":"publisher","DOI":"10.1016\/j.tracli.2019.06.017"},{"key":"10","doi-asserted-by":"publisher","DOI":"10.4103\/ajts.ajts_112_18"},{"issue":"51","key":"11","first-page":"18","article-title":"An\u00e9mie chez les donneurs de sang volontaires apr\u00e8s v\u00e9rification de l'h\u00e9moglobine pr\u00e9-don au Centre de Transfusion Sanguine de Libreville\/Anemia in voluntary blood donors after verification of pre-donation hemoglobin at the Libreville Blood Transfusion Center","volume":"20","author":"M.
