Introduction:

prematurity is the first cause of neonatal and infant morbidity and mortality and shows complications, both in early term and late preterm neonates.

Objective:

to characterize the behavior of late preterm and early term neonates assisted at the Neonatology Service of the Mariana Grajales University Hospital of Gynecology and Obstetrics during the period from January to December 2019.

Methods:

an observational, descriptive and cross-sectional research was carried out from January to December 2019; the population consisted of 519 neonates.

Results:

maternal ages between 18 and 34 years of age predominated in both groups and the extreme ages in the early term group with respect to the late preterm group stood out. The most frequent neonatal morbidity in both groups was jaundice, physiological icterus aggravated by prematurity in the late preterm group and metabolic disorders in the early term group.

Conclusions:

the early term group predominated over the late preterm group. Male gender and low birth weight were more frequent in the late preterm group and female gender and normal weight in the early term group and almost all the newborns were alive at medical discharge.
