Abstract
BACKGROUND: The recent increase in early term birth rates represents a growing challenge to public health given the association between early term birth and neonatal morbidities. We compared the risk of respiratory morbidity between early term and full-term infants. METHODS: This retrospective cohort population study included infants born at 37-41 weeks' gestation in a single tertiary care university hospital between 2014 and 2016. Newborns were categorized as early term (37-38 weeks) and full term (39-41 weeks). The primary outcome was respiratory morbidity. RESULTS: Of the 4,894 babies born at 37-41 weeks gestational age, 31% (n = 1,521) were early term births. The rate of cesarean deliveries, which were often elective, was higher for early term than for full-term newborns (P = 0.001). Compared with full-term newborns, early term newborns, had significantly higher risks of respiratory morbidity (13.2 % vs 6.3 %; odds ratio [OR], 2.28, P = 0.001), respiratory distress syndrome (0.5 % vs 0 %, P = 0.001), transient tachypnea of the newborn (11.2 % vs 4.6 %; OR, 2.72, P = 0.001), continuous positive airway pressure use (9.7 % vs 3.7 %; OR, 2.82, P = 0.001), and ventilation support (1.4% vs 0.4%; OR, 4.11, P = 0.001). CONCLUSIONS: The elevated frequency of respiratory morbidity in early term infants emphasizes the importance of early term birth interventions. More than half of the early term births were elective cesarean sections; interventions should therefore focus on reducing elective cesarean procedures at the time of first birth.
