Method: To determine if the new CCs, built excluding mothers with an abnormal weight, are better than standard CCs at identifying SGA. A total of 16,122 neonates were identified as SGA, LGA, or AGA, using the two models. Logistic regression and analysis of covariance were used to calculate the OR and CI for adverse outcomes by group. Gestational age was considered as a covariable. Results: The SGA rates by the new CCs and by the standard CCs were 11.8% and 9.7%, respectively. The SGA rate only by the new CCs was 18% and the SGA rate only by the standard CCs was 0.01%. Compared to AGA by both models, SGA by the new CCs had increased rates of cesarean section, (OR 1.53 (95% CI 1.19, 1.96)), prematurity (OR 2.84 (95% CI 2.09, 3.85)), NICU admission (OR 5.41 (95% CI 3.47, 8.43), and adverse outcomes (OR 1.76 (95% CI 1.06, 2.60). The strength of these associations decreased with gestational age. Conclusion: The use of the new CCs allowed for a more accurate identification of SGA at risk of adverse perinatal outcomes as compared to the standard CCs.<\/jats:p>","DOI":"10.3390\/nu15030587","type":"journal-article","created":{"date-parts":[[2023,1,23]],"date-time":"2023-01-23T04:19:22Z","timestamp":1674447562000},"page":"587","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Abnormal Maternal Body Mass Index and Customized Fetal Weight Charts: Improving the Identification of Small for Gestational Age Fetuses and Newborns"],"prefix":"10.3390","volume":"15","author":[{"given":"Nieves Luisa","family":"Gonz\u00e1lez Gonz\u00e1lez","sequence":"first","affiliation":[{"name":"Department of Obstetrics and Gynecology, University of La Laguna, Hospital Universitario de Canarias, 38200 Tenerife, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0781-9161","authenticated-orcid":false,"given":"Enrique","family":"Gonz\u00e1lez D\u00e1vila","sequence":"additional","affiliation":[{"name":"Department of Mathematics, Statistics and Operations Research, IMAULL, University of La Laguna, 38200 Tenerife, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Agustina","family":"Gonz\u00e1lez Mart\u00edn","sequence":"additional","affiliation":[{"name":"Department of Obstetrics and Gynecology, Hospital Universitario Ntra Sra de Candenlaria, 38200 Tenerife, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Marina","family":"Armas","sequence":"additional","affiliation":[{"name":"Department of Pediatrics, Evangelisches Krakenhaus K\u00f6nig Elisabeth Herzberge, 10365 Berlin, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Laura","family":"Tasc\u00f3n","sequence":"additional","affiliation":[{"name":"Department of Obstetrics and Gynecology, University of La Laguna, Hospital Universitario de Canarias, 38200 Tenerife, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2100-7693","authenticated-orcid":false,"given":"Alba","family":"Farras","sequence":"additional","affiliation":[{"name":"Maternal-Fetal Medicine Unit, Department of Obstetrics, Hospital Universitari Vall d\u2019Hebron, Universitat Aut\u00f3noma de Barcelona, Pg. de la Vall d'Hebron, 119, 08035 Barcelona, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Teresa","family":"Higueras","sequence":"additional","affiliation":[{"name":"Maternal-Fetal Medicine Unit, Department of Obstetrics, Hospital Universitari Vall d\u2019Hebron, Universitat Aut\u00f3noma de Barcelona, Pg. de la Vall d'Hebron, 119, 08035 Barcelona, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3030-3833","authenticated-orcid":false,"given":"Manel","family":"Mendoza","sequence":"additional","affiliation":[{"name":"Maternal-Fetal Medicine Unit, Department of Obstetrics, Hospital Universitari Vall d\u2019Hebron, Universitat Aut\u00f3noma de Barcelona, Pg. de la Vall d'Hebron, 119, 08035 Barcelona, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Elena","family":"Carreras","sequence":"additional","affiliation":[{"name":"Maternal-Fetal Medicine Unit, Department of Obstetrics, Hospital Universitari Vall d\u2019Hebron, Universitat Aut\u00f3noma de Barcelona, Pg. de la Vall d'Hebron, 119, 08035 Barcelona, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mar\u00eda","family":"Goya","sequence":"additional","affiliation":[{"name":"Maternal-Fetal Medicine Unit, Department of Obstetrics, Hospital Universitari Vall d\u2019Hebron, Universitat Aut\u00f3noma de Barcelona, Pg. de la Vall d'Hebron, 119, 08035 Barcelona, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2023,1,22]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"33","DOI":"10.1053\/j.semperi.2003.12.002","article-title":"Customized fetal growth standards: Rationale and clinical application","volume":"28","author":"Gardosi","year":"2004","journal-title":"Semin.
