However, only a few studies have examined the impact of race\/ethnicity on the outcomes of premature infants. &lt;b&gt;&lt;i&gt;Objective:&lt;\/i&gt;&lt;\/b&gt; To report the rates of mortality and severe neonatal morbidity among multiple gestational age (GA) groups stratified by race\/ethnicity. &lt;b&gt;&lt;i&gt;Methods:&lt;\/i&gt;&lt;\/b&gt; A retrospective cohort study utilizing linked birth certificate, hospital discharge, readmission, and death records up to 1 year of life. Live-born infants \u226436 weeks born in the period 2007-2012 were included. Maternal self-identified race\/ethnicity, as recorded on the birth certificate, was used. ICD-9 diagnostic and procedure codes captured neonatal morbidities (intraventricular hemorrhage, retinopathy of prematurity, periventricular leukomalacia, bronchopulmonary dysplasia, and necrotizing enterocolitis). Multiple logistic regression was performed to evaluate the impact of race\/ethnicity on mortality and morbidity, adjusting for GA, birth weight, sex, and multiple gestation. &lt;b&gt;&lt;i&gt;Results:&lt;\/i&gt;&lt;\/b&gt; Our cohort totaled 245,242 preterm infants; 26% were white, 46% Hispanic, 8% black, and 12% Asian. At 22-25 weeks, black infants were less likely to die than white infants (odds ratio [OR] 0.76; 95% confidence interval [CI] 0.62-0.94). However, black infants born at 32-34 weeks (OR 1.64; 95% CI 1.15-2.32) or 35-36 weeks (OR 1.57; 95% CI 1.00-2.24) were more likely to die. Hispanic infants born at 35-36 weeks were less likely to die than white infants (OR 0.66; 95% CI 0.50-0.87). Racial disparities at different GAs were also detected for severe morbidities. &lt;b&gt;&lt;i&gt;Conclusions:&lt;\/i&gt;&lt;\/b&gt; The impact of race\/ethnicity on mortality and severe morbidity varied across GA categories in preterm infants. Disparities persisted even after adjusting for important potential confounders.<\/jats:p>","DOI":"10.1159\/000480536","type":"journal-article","created":{"date-parts":[[2017,10,26]],"date-time":"2017-10-26T21:01:57Z","timestamp":1509051717000},"page":"44-54","source":"Crossref","is-referenced-by-count":74,"title":["Racial and Ethnic Disparities in Preterm Infant Mortality and Severe Morbidity: A Population-Based Study"],"prefix":"10.1159","volume":"113","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3847-4602","authenticated-orcid":false,"given":"James G.","family":"Anderson","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Elizabeth E.","family":"Rogers","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rebecca J.","family":"Baer","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Scott P.","family":"Oltman","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Randi","family":"Paynter","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"J.
