We analyzed data for neonates who died within 28 days of birth, focusing on mortality before 24\u2009h (early death). Multilevel multivariate logistic regression was used to calculate crude and adjusted odds ratios (aORs) for early death based on 5\u2010min Apgar scores and other neonatal factors. The random effects variable in this model was altitude at which neonates were attended; this component of the model allows the intercept estimates to vary randomly among the groups of altitude, suggesting that there are differences between these groups that could influence the study results at which the neonates were attended.\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:bold>Results:<\/jats:bold>\n                    Of 2144 neonates analyzed, 53.2% were male, with an average gestational age of 30.8 weeks and a mean birth weight of 1525.2\u2009g. More than half (56.0%) were delivered by caesarean section. Common comorbidities included prematurity (39.4%), asphyxia (31.2%), and infections (24.7%). Also, 17.4% had Apgar scores of \u2264\u20093. After adjustment, Apgar scores of \u2264\u20093 were linked to significantly increased odds of death before 24\u2009h, with an aOR of 20.65 (95% CI: 5.99\u201371.28,\n                    <jats:italic>p<\/jats:italic>\n                    &lt; 0.001).\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:bold>Conclusions:<\/jats:bold>\n                    This study demonstrated that the Apgar score, among other determinants, was significantly associated with early neonatal mortality (before the first 24\u2009h). This association was independent of type of delivery, comorbidities, disorders related to asphyxia, prematurity, infections, and other medical disorders, as well as varying levels of care from primary to tertiary. These findings underscore the importance of Apgar evaluation in neonates and suggest a predictive value of the score for early neonatal mortality.\n                  <\/jats:p>","DOI":"10.1155\/ijpe\/4225987","type":"journal-article","created":{"date-parts":[[2025,5,19]],"date-time":"2025-05-19T05:04:13Z","timestamp":1747631053000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Early Neonatal Mortality (&lt;\u200924\u2009h) in Ecuador: A Population\u2010Based Study on the Impact of Apgar Score, Gestational Age, Birth Weight, Delivery Type, and Healthcare Level"],"prefix":"10.1155","volume":"2025","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6639-727X","authenticated-orcid":false,"given":"Iv\u00e1n","family":"Due\u00f1as-Esp\u00edn","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mar\u00eda Alejandra","family":"Montaluisa","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andrea","family":"Aguilar-Molina","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fernando","family":"Aguinaga","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Luciana","family":"Armijos-Acurio","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5016-3834","authenticated-orcid":false,"given":"Ruth","family":"Jimbo-Sotomayor","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"\u00c1ngela Le\u00f3n","family":"C\u00e1ceres","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mar\u00eda F.","family":"Rivadeneira","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Silvana","family":"Rivera-Guerra","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8258-8746","authenticated-orcid":false,"given":"Xavier","family":"S\u00e1nchez","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Betzab\u00e9","family":"Tello","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2025,5,19]]},"reference":[{"key":"e_1_2_11_1_2","first-page":"260","article-title":"A Proposal for a New Method of Evaluation of the Newborn Infant","volume":"32","author":"Apgar V.","year":"1953","journal-title":"Current Researches in Anesthesia & Analgesia"},{"key":"e_1_2_11_2_2","doi-asserted-by":"publisher","DOI":"10.1542\/peds.2015-2651"},{"key":"e_1_2_11_3_2","doi-asserted-by":"publisher","DOI":"10.1001\/archpedi.1962.02080030421015"},{"key":"e_1_2_11_4_2","doi-asserted-by":"publisher","DOI":"10.1097\/01.AOG.0000445580.65983.d2"},{"key":"e_1_2_11_5_2","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0069072"},{"key":"e_1_2_11_6_2","doi-asserted-by":"publisher","DOI":"10.1056\/NEJMoa1915075"},{"key":"e_1_2_11_7_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0140-6736(14)61135-1"},{"key":"e_1_2_11_8_2","doi-asserted-by":"publisher","DOI":"10.1001\/archpedi.154.3.294"},{"key":"e_1_2_11_9_2","doi-asserted-by":"publisher","DOI":"10.1136\/archdischild-2015-308458"},{"key":"e_1_2_11_10_2","unstructured":"INEC Estad\u00edsticas Vitales Registro Estad\u00edstico de Defunciones Generales de 2022 Regist.
