ABSTRACT

Introduction: Cesarean section has been associated with neonatal complications such as prematurity, respiratory distress syndrome, persistent pulmonary hypertension and thermal dysfunction. Objective: To determine the association between delivery mode and frequency of late preterm births in a regional hospital of central Mexico. Methods: We performed a retrospective cohort study. We reviewed the records of births between January 2006 and September 2010 at the Regional Hospital of Salamanca Pemex. We recorded maternal variables such as age, disease, number of pregnancies and prenatal care. The newborn variables were weight, sex, gestational age, Apgar, Silverman, delivery mode. Descriptive statistics were calculated and the risk for late-preterm birth in relation to delivery mode. Results: We reviewed the records of 879 births, 380 (43.2%) were vaginal delivery and 499 (56.8%) cesarean sections. Most cesarean sections (91%) were considered as electives and 9% as urgent. The gestational age of those born by cesarean section was reduced gradually from 2006 to 2010. The incidence rate of late-preterm infants in the cesarean was 16.6% and 5.5% in those born by vaginal delivery (RR = 3.0, 95% CI: 1.9 to 4.7). Eighty-three percent of late preterm infants were admitted to the Neonatal Intensive Care Unit. Conclusions: The cesarean section is associated with increased incidence of late preterm births. In our series, cesarean section represented three times more likely to get a late preterm infant.
