ROMERO-MALDONADO, Silvia; CARRERA-MUINOS, Sandra  and  RODRIGUEZ-LOPEZ, Orlando. Late premature newborn, morbidity in the first month of life compared with term infants. Perinatol. Reprod. Hum. [online]. 2013, vol.27, n.3, pp.161-165. ISSN 2524-1710.

Introduction: In recent years there has been an increase in the number of births of infants near term; this late prematurity is associated with increased neonatal morbidity and mortality, so it is important to know the differences in morbidity in this group of patients compared with term newborns, during the first month of life. Objective: To evaluate the early morbidity and during the first month of life of late preterm compared with term infants. Material and methods: We performed a comparative study of two cohorts of infants. Cohort 1: Late preterm infants from 34 to 36.6 weeks of gestation and Cohort 2; term infants. The morbidity was recorded during the first month of life, 15 variables were measure. We used descriptive statistic, for comparison between groups Student's t and to compare morbidity between groups the relative risk with 95% confidence interval. Results: We included 59 late preterm and 69 term infants. Of the maternal factors studied no statistically significant difference was found; respect to neonatal morbidity, we identified a great risk in the late preterm risk for hyperbilirubinemia (OR 1.7, CI 95% 1.1-2.65), gastroesophageal reflux (OR 1.8, CI 95% 1.1-289) and feeding difficulties (OR: 1.66, CI 95% 1.14-2.42). Conclusions: The risk of morbidity in late preterm found are those related to their own prematurity. In this study, there was no pathology associated with maternal morbidity in late preterm.
