Maternal smoking was associated with prolonged mechanical ventilation and respiratory support during the neonatal intensive care unit admission. Preexisting hypertension was associated with a twofold (P\u2009=\u20090.04) increase in odds for BPD. Lower gestational age and birth weight z-scores were associated with BPD. Preterm infants who were exposed to maternal smoking had higher rates of late respiratory disease during childhood. Twenty-two percent of infants diagnosed with BPD and 34% of preterm infants without BPD had no clinical signs of late respiratory disease during early childhood.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>We conclude that maternal smoking and hypertension increase the odds for developing BPD after preterm birth, and that maternal smoking is strongly associated with increased odds for late respiratory morbidities during early childhood. These findings suggest that in addition to the BPD diagnosis at 36 weeks, other factors modulate late respiratory outcomes during childhood. We speculate that measures to reduce maternal smoking not only will lower the risk for preterm birth but also will improve late respiratory morbidities after preterm birth.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1164\/rccm.201612-2414oc","type":"journal-article","created":{"date-parts":[[2017,3,1]],"date-time":"2017-03-01T17:12:49Z","timestamp":1488388369000},"page":"364-374","source":"Crossref","is-referenced-by-count":176,"title":["Antenatal Determinants of Bronchopulmonary Dysplasia and Late Respiratory Disease in Preterm Infants"],"prefix":"10.1093","volume":"196","author":[{"given":"Lindsey A.","family":"Morrow","sequence":"first","affiliation":[{"name":"Pediatric Heart Lung Center, Department of Pediatrics, Children\u2019s Hospital Colorado"},{"name":"Department of Biostatistics and Informatics"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Brandie D.","family":"Wagner","sequence":"additional","affiliation":[{"name":"Pediatric Heart Lung Center, Department of Pediatrics, Children\u2019s Hospital Colorado"},{"name":"Department of Biostatistics and Informatics"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"David A.","family":"Ingram","sequence":"additional","affiliation":[{"name":"Section of Neonatal-Perinatal Medicine, Department of Pediatrics, Indiana University School of Medicine, Indianapolis, Indiana"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Brenda B.","family":"Poindexter","sequence":"additional","affiliation":[{"name":"Section of Neonatal-Perinatal Medicine, Department of Pediatrics, Indiana University School of Medicine, Indianapolis, Indiana"},{"name":"Perinatal Institute, Cincinnati Children\u2019s Hospital Medical Center, Cincinnati, Ohio"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kurt","family":"Schibler","sequence":"additional","affiliation":[{"name":"Perinatal Institute, Cincinnati Children\u2019s Hospital Medical Center, Cincinnati, Ohio"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"C.
