The purpose of this study is to provide a race- and gender-specific model for predicting 1-year survival rates for extremely low birth weight (ELBW) infants by using population-based data.<\/jats:p><jats:p>METHODS. Birth and death certificates were analyzed for all children (N = 5076) with birth weights between 300 g and 1000 g who were born in Florida between 1996 and 2000. Semiparametric, multivariate, logistic regression analysis was used to model 1-year survival probabilities as a function of birth weight, gestational age, mother's race, and infant's gender. Estimated survival rates among different race\/gender groups were compared by using odds ratios (ORs).<\/jats:p><jats:p>RESULTS. One-year survival rates for 5076 ELBW infants born between 1996 and 2000 did not change during the 5-year period (60\u201362%). The survival rate at \u2264500 g was \u226414% (n = 716). Survival rates at 501 to 600 g and 601 to 700 g were 36% and 62%, respectively. The survival rate reached &amp;gt;85% for infants of &amp;gt;800 g. Modeling indicated a survival advantage for female infants, compared with male infants (OR: 1.7; 95% confidence interval: 1.5\u20131.9), and for black infants, compared with white infants (OR: 1.3; 95% confidence interval: 1.1\u20131.5). Black female infants had 2.1 greater odds of survival than did white male infants.<\/jats:p><jats:p>CONCLUSIONS. This population-based study highlights the significant race and gender differences in 1-year survival rates for ELBW infants, as well as the interactions of these 2 factors. These findings can assist obstetricians and neonatologists not only in the care of ELBW infants but also in frank discussions with families.<\/jats:p>","DOI":"10.1542\/peds.2005-1286","type":"journal-article","created":{"date-parts":[[2006,1,5]],"date-time":"2006-01-05T02:28:34Z","timestamp":1136428114000},"page":"e106-e112","source":"Crossref","is-referenced-by-count":52,"title":["Racial and Gender Differences in the Viability of Extremely Low Birth Weight Infants: A Population-Based Study"],"prefix":"10.1542","volume":"117","author":[{"given":"Steven B.","family":"Morse","sequence":"first","affiliation":[{"name":"Departments of Pediatrics"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Samuel S.","family":"Wu","sequence":"additional","affiliation":[{"name":"Statistics"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Changxing","family":"Ma","sequence":"additional","affiliation":[{"name":"Statistics"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mario","family":"Ariet","sequence":"additional","affiliation":[{"name":"Medicine, College of Medicine, University of Florida, Gainesville, Florida"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michael","family":"Resnick","sequence":"additional","affiliation":[{"name":"Departments of Pediatrics"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jeffrey","family":"Roth","sequence":"additional","affiliation":[{"name":"Departments of Pediatrics"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"417","published-online":{"date-parts":[[2006,1,1]]},"reference":[{"key":"2021120819440611300_R1","doi-asserted-by":"crossref","unstructured":"Martin JA, Kochanek KD, Strobino DM, Guyer B, MacDorman MF.
