Groups studied: \u2018Term-weeks\u2019 and \u2018Term-days\u2019 (term newborns with gestational age in weeks and days, respectively),\u00a0\u2018Preterm-weeks\u2019 and \u2018Preterm-days\u2019 (preterm newborns with gestational age in weeks and days, respectively).Results: A total of 14 056 newborns were included, 6% preterm. Using the Intergrowth 21st growth charts, the groups \u2018Term-weeks\u2019\u00a0(n = 12 081), \u2018Term-days\u2019 (n = 1118), \u2018Preterm-weeks\u2019 (n = 617) and \u2018Preterm-days\u2019 (n = 240), classified as small for gestational age\u00a0according to the Fenton &amp; Kim 2013 growth charts were adequate for gestational age in 52.8%, 57.8%, 37.7% and 9.3% respectively;\u00a0and 9.2%, 9.2%, 5.9% and 0.6% of adequate for gestational age newborns were large for gestational age, respectively. In the \u2018Pretermdays\u2019\u00a0group, 7.9% of adequate for gestational age newborns were small for gestational age and 22.2% of large for gestational age\u00a0newborns were adequate for gestational age, all with gestational age below 231 days.Discussion: The use of the Intergrowth 21st growth charts in this sample resulted in a lower number of newborns being classified as\u00a0small for gestational age, except in very preterm newborns.Conclusion: Considering the results obtained, we suggest that Portuguese maternity hospitals use the Intergrowth 21st instead of the\u00a0Fenton &amp; Kim 2013 growth charts. However, more studies are needed to confirm these results.<\/jats:p>","DOI":"10.20344\/amp.10990","type":"journal-article","created":{"date-parts":[[2019,11,18]],"date-time":"2019-11-18T21:46:43Z","timestamp":1574113603000},"page":"15-21","source":"Crossref","is-referenced-by-count":7,"title":["Performance of Intergrowth 21st Growth Charts in the Diagnosis of Small and Large for Gestational Age in Term and Preterm Newborns"],"prefix":"10.20344","volume":"33","author":[{"given":"B\u00e1rbara","family":"Marques","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rosa","family":"Martins","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Teresa","family":"Rodrigues","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gra\u00e7a","family":"Oliveira","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Margarida","family":"Abrantes","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"8464","published-online":{"date-parts":[[2020,1,3]]},"container-title":["Acta M\u00e9dica Portuguesa"],"original-title":[],"link":[{"URL":"https:\/\/www.actamedicaportuguesa.com\/revista\/index.php\/amp\/article\/download\/10990\/5802","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.actamedicaportuguesa.com\/revista\/index.php\/amp\/article\/download\/10990\/5802","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2022,10,24]],"date-time":"2022-10-24T20:51:12Z","timestamp":1666644672000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.actamedicaportuguesa.com\/revista\/index.php\/amp\/article\/view\/10990"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2020,1,3]]},"references-count":0,"journal-issue":{"issue":"1","published-online":{"date-parts":[[2020,1,3]]}},"URL":"https:\/\/doi.org\/10.20344\/amp.10990","relation":{},"ISSN":["1646-0758","0870-399X"],"issn-type":[{"value":"1646-0758","type":"electronic"},{"value":"0870-399X","type":"print"}],"subject":[],"published":{"date-parts":[[2020,1,3]]}}}
