To describe the iron status profile and to propose hemoglobin adjustment factors for altitude for children aged 6 to 8 months in Lima, Arequipa, Cusco and Puno. Materials and methods. Cross-sectional study in children aged 6 to 8 months from four cities. We measured hemoglobin and other iron biomarkers, C-reactive protein (CRP), among others. To estimate the adjustment equation, we applied an exponential regression. We excluded children with iron deficiency (ID) and\/or inflammation. Results. The proportions of ID were higher in Puno and Arequipa, while inflammation did not exceed 19% in any of the cities. Hemoglobin showed an exponential increase at higher altitude. The adjustment equation was: 10.34249 x (1.00007 ^ Alt). Conclusions. Children residing in Arequipa and Puno showed higher rates of ID and lower iron reserves; furthermore, the increase in hemoglobin by altitude was exponential, showing the need to adjust hemoglobin at altitude.<\/jats:p>","DOI":"10.17843\/rpmesp.2023.404.12573","type":"journal-article","created":{"date-parts":[[2023,12,23]],"date-time":"2023-12-23T04:54:24Z","timestamp":1703307264000},"page":"395","source":"Crossref","is-referenced-by-count":6,"title":["Estado de hierro y propuesta de ajuste de hemoglobina por altitud en ni\u00f1os de 6 a 8 meses residentes en Lima, Arequipa, Cusco y Puno","Iron status and a proposal for hemoglobin adjustment by altitude in children 6 to 8 months old living in Lima, Arequipa, Cusco and Puno"],"prefix":"10.17843","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9159-7997","authenticated-orcid":false,"given":"Juan Pablo","family":"Aparco","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7690-0676","authenticated-orcid":false,"given":"Gabriela","family":"Santos-Antonio","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1815-8952","authenticated-orcid":false,"given":"William","family":"Bautista-Olortegui","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3863-3770","authenticated-orcid":false,"given":"Katherine","family":"Alvis-Chirinos","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6981-6150","authenticated-orcid":false,"given":"Patricia","family":"Velarde-Delgado","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1592-4586","authenticated-orcid":false,"given":"Paul","family":"Hinojosa-Mamani","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7084-088X","authenticated-orcid":false,"given":"Gilmer","family":"Solis-Sanchez","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3352-2123","authenticated-orcid":false,"given":"Flor Eliana","family":"Santa Cruz","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6929-5834","authenticated-orcid":false,"given":"Nelly","family":"Zavaleta","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"7920","published-online":{"date-parts":[[2023,12,18]]},"container-title":["Revista Peruana de Medicina Experimental y Salud P\u00fablica"],"original-title":[],"link":[{"URL":"https:\/\/rpmesp.ins.gob.pe\/index.php\/rpmesp\/article\/download\/12573\/5488","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/rpmesp.ins.gob.pe\/index.php\/rpmesp\/article\/download\/12573\/5488","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,12,23]],"date-time":"2023-12-23T04:54:48Z","timestamp":1703307288000},"score":1,"resource":{"primary":{"URL":"https:\/\/rpmesp.ins.gob.pe\/index.php\/rpmesp\/article\/view\/12573"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2023,12,18]]},"references-count":0,"URL":"https:\/\/doi.org\/10.17843\/rpmesp.2023.404.12573","relation":{},"ISSN":["1726-4642","1726-4634"],"issn-type":[{"value":"1726-4642","type":"electronic"},{"value":"1726-4634","type":"print"}],"subject":[],"published":{"date-parts":[[2023,12,18]]}}}
