Abstract
BACKGROUND: Increasing evidence is demonstrating that infants born early on during the term period are at increased risk of morbidity compared with infants born closer to a complete 40 week gestational pregnancy. The purpose of this study was to compare early term [gestation age (GA): 37-37 6/7 weeks] neonatal outcomes with those of other full term neonatal intensive care unit (NICU) admissions. METHODS: Retrospective chart review of all term infants admitted to the NICU at New York University Langone Medical Center over a 17 month period. Subjects were grouped and analyzed according to their GA at birth: 1) early term infants (GA between 37 0/7 to 37 6/7 weeks) and 2) other term infants (38 0/7 weeks and older). RESULTS: Early term infants were more likely to require NICU care than other term infants [relative risk: 1.42, 95% confidence interval (CI)=1.07-1.88), P=0.01]. In the NICU, they are more likely to manifest respiratory distress syndrome [odds ratio (OR)=5.7, 95% CI=1.6-19.8, P<0.01] and hypoglycemia (OR=4.6, 95% CI=2.0-10.4, P<0.001). In addition, early term neonates were more likely to be born via elective cesarean section than other term neonates (OR=4.1, 95% CI=2.0-8.5, P<0.001). CONCLUSIONS: Being born at early term is associated with increased risk of respiratory disease and hypoglycemia requiring neonatal intensive care. Further efforts directed at decreasing early term deliveries may be warranted.
