title: Early neonatal morbidities in late preterm infants.
abstract: OBJECTIVE
  To compare early neonatal morbidity (within first 7 days of life) in late preterm infants with term infants.
  
  
  METHODS
  Prospective cohort study.
  
  
  METHODS
  All live inborn late preterm infants (34 0/7 to 36 6/7 weeks) and term infants (37 0/7 to 41 6/7 weeks).
  
  
  RESULTS
  Any of the predefined medical conditions listed in the study, resulting in post- delivery inpatient hospital observation, admission, or readmission in first 7 days of life.
  
  
  RESULTS
  363 late preterm infants and 2707 term infants were included in study. Two hundred fifty seven (70.8 %) of late preterm and 788 (29.1%) of term infants had at least one of the predefined neonatal conditions. Late preterm infants were at significantly higher risk for overall morbidity due to any cause (P<0.001; adjusted Odds Ratio (OR): 5.5; 95% CI: 4.2-7.1), respiratory morbidity (P<0.001; adjusted OR: 7.5; 95% CI: 4.2-12.3), any ventilation (non invasive or invasive) (P=0.001; adjusted OR: 4.2; 95% CI: 2-8.9), jaundice (P<0.001; adjusted OR: 3.4; 95% CI: 2.7-4.4), hypoglycemia (P<0.001; adjusted OR: 4.5; 95% CI: 2.6-7.7), and probable sepsis (P<0.001; adjusted OR: 3.2; 95% CI: 1.6-6.5). The incidence of morbidities increased from 23% at 40 weeks to 30%, 39.7%, 67.5%, 89% and 87.9% at 38, 37, 36, 35 and 34 weeks, respectively (P<0.001).
  
  
  CONCLUSIONS
  Compared with term infants, late preterm infants are at high risk for respiratory morbidity, need of ventilation (non invasive or invasive), jaundice, hypoglycemia, sepsis, and probable sepsis. All gestations except 39 weeks were at significantly higher risk for morbidity with 40 weeks as reference term.
