The \u201cBirth in Brazil\u201d study interviewed 23\u00a0894 puerperal women between 2011 and 2012, in all regions of Brazil. The current analysis included 17\u00a0994 adult mothers and their newborns (15\u00a0448 aged between 20\u201334\u00a0years, and 2536\u00a0\u2265\u00a035\u00a0years). A propensity score was used to assess the likelihood of AMA women giving birth to premature or early\u2010term infants (spontaneous or provider\u2010initiated) compared to women aged 20\u201334\u00a0years. To balance the groups, we used maternal, prenatal, and childbirth characteristics.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The general prematurity rate was 10.24%, of which the majority of births were spontaneous (55.73%). Conversely, early\u2010term births were more often provider\u2010initiated (54.81%). AMA did not increase the chance of premature births, whether spontaneous or provider\u2010initiated. However, AMA was associated with a higher rate of provider\u2010initiated early\u2010term birth (OR\u00a0=\u00a01.48; 95% CI: 1.23\u20131.77).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>AMA alone does not contribute to premature birth; AMA\u2019s independent association with provider\u2010initiated early\u2010term birth may not be based solely on clinical indications.<\/jats:p><\/jats:sec>","DOI":"10.1002\/ijgo.14057","type":"journal-article","created":{"date-parts":[[2021,12,3]],"date-time":"2021-12-03T16:21:12Z","timestamp":1638548472000},"page":"173-181","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["A population\u2010based study of the relationship between advanced maternal age and premature\/early\u2010term birth in Brazil"],"prefix":"10.1002","volume":"159","author":[{"given":"Silvana Granado","family":"Nogueira da Gama","sequence":"first","affiliation":[{"name":"Sergio Arouca National School of Public Health Oswaldo Cruz Foundation  Rio de Janeiro Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0894-3241","authenticated-orcid":false,"given":"Katrini Guidolini","family":"Martinelli","sequence":"additional","affiliation":[{"name":"Federal University of Espirito Santo (UFES) Postgraduate Program in Public Health  Vitoria Esp\u00edrito Santo Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Barbara\u00a0Almeida","family":"Soares Dias","sequence":"additional","affiliation":[{"name":"Sergio Arouca National School of Public Health Oswaldo Cruz Foundation  Rio de Janeiro Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ana Paula","family":"Pereira\u2010Esteves","sequence":"additional","affiliation":[{"name":"Sergio Arouca National School of Public Health Oswaldo Cruz Foundation  Rio de Janeiro Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Maria","family":"do Carmo Leal","sequence":"additional","affiliation":[{"name":"Sergio Arouca National School of Public Health Oswaldo Cruz Foundation  Rio de Janeiro Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Edson Theodoro","family":"dos Santos\u2010Neto","sequence":"additional","affiliation":[{"name":"Federal University of Espirito Santo (UFES) Postgraduate Program in Public Health  Vitoria Esp\u00edrito Santo Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2021,12,20]]},"reference":[{"key":"e_1_2_9_2_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1728-4457.2016.00105.x"},{"key":"e_1_2_9_3_1","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0164462"},{"key":"e_1_2_9_4_1","unstructured":"Brazil.
