Short-term morbidities in moderate and late preterm infants

Area of Science:

• Neonatology
• Perinatology
• Public Health

Background:

• Preterm birth, particularly moderate and late preterm infants (32-36 weeks), presents significant neonatal health challenges.
• Understanding the factors influencing neonatal outcomes in this population is crucial for improving care.

Purpose of the Study:

• To investigate the relationship between gestational age and neonatal morbidity in preterm infants.
• To identify maternal medical conditions and pregnancy/birth complications impacting neonatal outcomes.

Main Methods:

• A retrospective cohort study analyzed 870 preterm infants born between 32 and 36 weeks gestation.
• Stepwise regression analysis identified significant associations between gestational age, morbidities, and complications.

Main Results:

• Neonatal morbidity incidence rose sharply with decreasing gestational age, from 24% at 36 weeks to 93% at 32 weeks.
• Infants born at 32 weeks had a 4-fold increased risk of morbidity and 16-fold increased risk of NICU admission compared to 36-week infants.
• Hyperbilirubinemia and respiratory issues were most common; intrauterine growth restriction, preeclampsia, and male gender were significant risk factors.

Conclusions:

• Nearly half of all moderate and late preterm infants experienced neonatal morbidity.
• Several maternal and perinatal factors significantly predict NICU admission and hospitalization duration, highlighting areas for targeted intervention.
