We estimated IMR for the period 2014\u20132016 using vital registration for 286 cities above 100\u00a0000 people in eight countries. Using national censuses, we calculated population size, growth and three socioeconomic scores reflecting living conditions, service provision and population educational attainment. We included mass transit availability of bus rapid transit and subway. Using Poisson multilevel regression, we estimated the per cent difference in IMR for a one SD (1SD) difference in city-level predictors.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec id=\"s3\">\n                  <jats:title>Results<\/jats:title>\n                  <jats:p>Of the 286 cities, 130 had &lt;250\u00a0000 inhabitants and 5 had &gt;5 million. Overall IMR was 11.2 deaths\/1000 live births. 57% of the total IMR variability across cities was within countries. Higher population growth, better living conditions, better service provision and mass transit availability were associated with 6.0% (95% CI \u22128.3 to 3.7%), 14.1% (95% CI \u221218.6 to \u22129.2), 11.4% (95% CI \u221216.1 to \u22126.4) and 6.6% (95% CI \u22129.2 to \u22123.9) lower IMR, respectively. Greater population size was associated with higher IMR. No association was observed for population-level educational attainment in the overall sample.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec id=\"s4\">\n                  <jats:title>Conclusion<\/jats:title>\n                  <jats:p>Improving living conditions, service provision and public transportation in cities may have a positive impact on reducing IMR in LA cities.<\/jats:p>\n               <\/jats:sec>","DOI":"10.1136\/jech-2020-215137","type":"journal-article","created":{"date-parts":[[2020,10,15]],"date-time":"2020-10-15T17:20:25Z","timestamp":1602782425000},"page":"264-270","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":46,"title":["Characterising variability and predictors of infant mortality in urban settings: findings from 286 Latin American cities"],"prefix":"10.1136","volume":"75","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8100-422X","authenticated-orcid":false,"given":"Ana F","family":"Ortigoza","sequence":"first","affiliation":[{"name":"Urban Health Collaborative, Drexel University, Philadelphia, Pennsylvania, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4101-1024","authenticated-orcid":false,"given":"Jos\u00e9 A","family":"Tapia Granados","sequence":"additional","affiliation":[{"name":"History and Political Science, Drexel University, Philadelphia, Pennsylvania, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4738-5468","authenticated-orcid":false,"given":"J Jaime","family":"Miranda","sequence":"additional","affiliation":[{"name":"CRONICAS Centre of Excellence in Chronic Diseases, Universidad Peruana Cayetano Heredia, Lima, Peru"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marcio","family":"Alazraqui","sequence":"additional","affiliation":[{"name":"Instituto de Salud Colectiva, Universidad Nacional de Lanus, Lanus, Argentina"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Diana","family":"Higuera","sequence":"additional","affiliation":[{"name":"Escuela de Medicina, Universidad de Los Andes, Bogota, Colombia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Georgina","family":"Villamonte","sequence":"additional","affiliation":[{"name":"CRONICAS Centre of Excellence in Chronic Diseases, Universidad Peruana Cayetano Heredia, Lima, Peru"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Am\u00e9lia Augusta de Lima","family":"Friche","sequence":"additional","affiliation":[{"name":"School of Medicine, Universidade Federal de Minas Gerais Faculdade de Medicina, Belo Horizonte, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tonatiuh","family":"Barrientos Gutierrez","sequence":"additional","affiliation":[{"name":"Instituto Nacional de Salud Publica, Mexico DF, Mexico"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ana V","family":"Diez Roux","sequence":"additional","affiliation":[{"name":"Urban Health Collaborative, Drexel University, Philadelphia, Pennsylvania, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"239","published-online":{"date-parts":[[2020,10,15]]},"reference":[{"key":"2025100303570136000_75.3.264.1","unstructured":"PAHO .
