We applied and adapted methods from the Institute of Medicine (IOM) and the European Food Safety Authority (EFSA) to estimate the NRV. Body iron losses, iron needs for growth and dietary iron bioavailability were estimated using both local and external data.<\/jats:p>\n <\/jats:sec>\n \n Setting:<\/jats:title>\n Rio de Janeiro, Brazil.<\/jats:p>\n <\/jats:sec>\n \n Participants:<\/jats:title>\n Data on dietary intake from a probabilistic sample of children aged 7\u201323 months in the city of Rio de Janeiro, Brazil, were used to estimate iron consumption and bioavailability.<\/jats:p>\n <\/jats:sec>\n \n Results:<\/jats:title>\n The mean physiological iron requirements were 0\u00b778 mg\/d (7\u201311 months, male), 0\u00b753 mg\/d (7\u201311 months, female), 0\u00b779 mg\/d (12\u201323 months, male) and 0\u00b754 mg\/d (12\u201323 months, female). Mean dietary iron bioavailability was 7\u00b75 % across all age and sex groups. AR and PRI were 10 mg\/d and 19 mg\/d for children aged 7\u201311 months, and 7 mg\/d and 13 mg\/d for those aged 12\u201323 months. NRV did not differ by sex.<\/jats:p>\n <\/jats:sec>\n \n Conclusion:<\/jats:title>\n The AR for children aged 7\u201311 and 12\u201323 months were 11 mg\/d and 8 mg\/d, respectively. The corresponding PRI were 20 mg\/d and 14 mg\/d. The estimated Brazilian NRV were higher than those of the IOM and EFSA. Iron bioavailability was the most influential factor explaining the differences from other NRV.<\/jats:p>\n <\/jats:sec>","DOI":"10.1017\/s1368980025101018","type":"journal-article","created":{"date-parts":[[2025,10,28]],"date-time":"2025-10-28T09:20:06Z","timestamp":1761643206000},"update-policy":"https:\/\/doi.org\/10.1017\/policypage","source":"Crossref","is-referenced-by-count":1,"title":["Iron reference intake values for 7- to 23-month-old Brazilian children"],"prefix":"10.1017","volume":"28","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9382-4724","authenticated-orcid":false,"given":"Alessandra da Silva","family":"Pereira","sequence":"first","affiliation":[{"id":[{"id":"https:\/\/ror.org\/04tec8z30","id-type":"ROR","asserted-by":"publisher"}],"name":"Universidade Federal do Estado do Rio de Janeiro"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"In\u00eas Rugani Ribeiro de","family":"Castro","sequence":"additional","affiliation":[{"name":"Universidade do Estado do Rio de Janeiro"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1101-8746","authenticated-orcid":false,"given":"Eliseu","family":"Verly-Junior","sequence":"additional","affiliation":[{"name":"Universidade do Estado do Rio de Janeiro"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"56","published-online":{"date-parts":[[2025,10,28]]},"container-title":["Public Health Nutrition"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.cambridge.org\/core\/services\/aop-cambridge-core\/content\/view\/S1368980025101018","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,11,13]],"date-time":"2025-11-13T07:39:47Z","timestamp":1763019587000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.cambridge.org\/core\/product\/identifier\/S1368980025101018\/type\/journal_article"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2025]]},"references-count":0,"journal-issue":{"issue":"1","published-online":{"date-parts":[[2025]]}},"alternative-id":["S1368980025101018"],"URL":"https:\/\/doi.org\/10.1017\/s1368980025101018","relation":{},"ISSN":["1368-9800","1475-2727"],"issn-type":[{"value":"1368-9800","type":"print"},{"value":"1475-2727","type":"electronic"}],"subject":[],"published":{"date-parts":[[2025]]},"assertion":[{"value":"\u00a9 The Author(s), 2025.
