Therefore, maternal and neonatal outcomes may not be the same. This paper aimed to analyze the association between pregestational BMI (pBMI) and gestational weight gain (GWG) with maternal and neonatal outcomes in adolescent and adult pregnant women. The authors performed an observational study that included 1112 women, where 52.6% (n = 585) were adolescents. Sociodemographic information, pBMI, GWG, neonatal anthropometric measures, and maternal and neonatal outcomes were obtained. Adolescent women had a mean lower (21.4 vs. 26.2, p \u2264 0.001) pBMI than adults and a higher gestational weight gain (12.3 vs. 10.7 kg, p \u2264 0.001). According to Poisson regression models, gestational diabetes is positively associated with insufficient GWG and with pregestational obesity. Furthermore, the probability of developing pregnancy-induced hypertension increased with pBMI of obesity compared to normal weight. Preeclampsia, anemia, and preterm birth were not associated with GWG. Insufficient GWG was a risk factor, and being overweight was a protective factor for low birth weight and small for gestational age. We conclude that pBMI, GWG, and age group were associated only with gestational diabetes and low birth weight.<\/jats:p>","DOI":"10.3390\/ijerph19010280","type":"journal-article","created":{"date-parts":[[2021,12,28]],"date-time":"2021-12-28T01:18:15Z","timestamp":1640654295000},"page":"280","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":12,"title":["Association of Pregestational BMI and Gestational Weight Gain with Maternal and Neonatal Outcomes in Adolescents and Adults from Mexico City"],"prefix":"10.3390","volume":"19","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5490-1363","authenticated-orcid":false,"given":"Reyna","family":"S\u00e1mano","sequence":"first","affiliation":[{"name":"Coordinaci\u00f3n de Nutrici\u00f3n y Bioprogramaci\u00f3n, Instituto Nacional de Perinatolog\u00eda, Secretar\u00eda de Salud, Mexico City 11000, Mexico"},{"name":"Programa de Posgrado Doctorado en Ciencias Biol\u00f3gicas y de la Salud, Divisi\u00f3n de Ciencias Biol\u00f3gicas y de la Salud, Universidad Aut\u00f3noma Metropolitana, Mexico City 04960, Mexico"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5741-0241","authenticated-orcid":false,"given":"Gabriela","family":"Chico-Barba","sequence":"additional","affiliation":[{"name":"Coordinaci\u00f3n de Nutrici\u00f3n y Bioprogramaci\u00f3n, Instituto Nacional de Perinatolog\u00eda, Secretar\u00eda de Salud, Mexico City 11000, Mexico"},{"name":"Escuela de Enfermer\u00eda, Facultad de Ciencias de la Salud, Universidad Panamericana, Mexico City 03920, Mexico"},{"name":"Programa de Maestr\u00eda y Doctorado en Ciencias M\u00e9dicas, Odontol\u00f3gicas y de la Salud, Universidad Nacional Aut\u00f3noma de M\u00e9xico, Mexico City 04510, Mexico"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8808-6739","authenticated-orcid":false,"given":"Mar\u00eda Eugenia","family":"Flores-Quijano","sequence":"additional","affiliation":[{"name":"Coordinaci\u00f3n de Nutrici\u00f3n y Bioprogramaci\u00f3n, Instituto Nacional de Perinatolog\u00eda, Secretar\u00eda de Salud, Mexico City 11000, Mexico"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8940-1729","authenticated-orcid":false,"given":"Estela","family":"God\u00ednez-Mart\u00ednez","sequence":"additional","affiliation":[{"name":"Coordinaci\u00f3n de Nutrici\u00f3n y Bioprogramaci\u00f3n, Instituto Nacional de Perinatolog\u00eda, Secretar\u00eda de Salud, Mexico City 11000, Mexico"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5301-9878","authenticated-orcid":false,"given":"Hugo","family":"Mart\u00ednez-Rojano","sequence":"additional","affiliation":[{"name":"Secci\u00f3n de Posgrado e Investigaci\u00f3n de la Escuela Superior de Medicina del Instituto Polit\u00e9cnico Nacional, Mexico City 11340, Mexico"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5870-1729","authenticated-orcid":false,"given":"Luis","family":"Ortiz-Hernandez","sequence":"additional","affiliation":[{"name":"Programa de Posgrado Doctorado en Ciencias Biol\u00f3gicas y de la Salud, Divisi\u00f3n de Ciencias Biol\u00f3gicas y de la Salud, Universidad Aut\u00f3noma Metropolitana, Mexico City 04960, Mexico"},{"name":"Departamento de Atenci\u00f3n a la Salud, Universidad Aut\u00f3noma Metropolitana Xochimilco, Mexico City 04960, Mexico"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Oralia","family":"N\u00e1jera-Medina","sequence":"additional","affiliation":[{"name":"Programa de Posgrado Doctorado en Ciencias Biol\u00f3gicas y de la Salud, Divisi\u00f3n de Ciencias Biol\u00f3gicas y de la Salud, Universidad Aut\u00f3noma Metropolitana, Mexico City 04960, Mexico"},{"name":"Departamento de Atenci\u00f3n a la Salud, Universidad Aut\u00f3noma Metropolitana Xochimilco, Mexico City 04960, Mexico"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mar\u00eda","family":"Hern\u00e1ndez-Trejo","sequence":"additional","affiliation":[{"name":"Departamento de Neurobiolog\u00eda del Desarrollo, Instituto Nacional de Perinatolog\u00eda, Secretar\u00eda de Salud, Mexico City 11000, Mexico"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Cristopher","family":"Hurtado-Solache","sequence":"additional","affiliation":[{"name":"Escuela de Ciencias de la Salud, Universidad del Valle de M\u00e9xico-Chapultepec, Mexico City 11810, Mexico"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2021,12,28]]},"reference":[{"key":"ref_1","unstructured":"Rasmussen, K.M., and Yaktine, A.L.
