| Popis: | Introduction: The preterm birth rate is on the rise, and late preterm deliveries account for 75% of preterm deliveries. Late preterm newborns were for many years considered full-term newborns; however, their particularities have been recognized in the last decade, particularly in terms of the higher rate of complications in the neonatal period. This study aimed to analyze the factors associated with greater morbidity in late preterm newborns. Methods: In this cross-sectional study we reviewed the medical records of mothers and their late preterm infants born at our hospital during a four-year period. Logistic binary regression analysis was used to identify predictors of morbidity and control the confounding variables. Results: The study included 576 newborns, of whom 28% (n = 164) had some morbidities, the most common of which included respiratory distress syndrome and hyperbilirubinemia. The morbidity rate varied inversely with gestational age. A lower gesta- tional age, being small for gestational age, and the incomplete use of antenatal corticosteroids were identified as risk factors for morbidities (p < 0.01). Antenatal corticosteroids were apparently more used on the newborns who later developed respiratory distress syndrome (p < 0.01). In contrast, type of delivery, medically assisted reproduction, and pregnancy morbidity did not influence neonatal morbidity. Discussion: Some well-known risk factors were confirmed for neonatal morbidity; however, there was no evidence to confirm the association between other determinants mentioned in previous studies and the increased risk of morbidity in our study samples, such as cesarean section, gemelarity, or fetal growth restriction. Introdução: A taxa de nascimento prematuro está a aumentar, e os recém-nascidos prematuros tardios correspondem a 75% de todos os partos prematuros. Os recém-nascidos prematuros tardios foram durante muitos anos considerados como recém-nascidos de termo, mas na última década as suas especificidades foram reconhecidas, principalmente no que se refere ao maior índice de complicações no período neonatal. O nosso objetivo é analisar quais os fatores associados a maior morbilidade neonatal nesta população. Métodos: Realizámos um estudo de coorte com revisão dos registos médicos dos prematuros tardios (e respetivas mães) nascidos no nosso hospital durante um período de 4 anos. A análise de regressão logística binária foi usada para identificar preditores de morbidade e controlar as variáveis confundidoras. Nível de significância considerado p |
