The purpose of this research was to assess the patterns of morbidity and mortality in late preterm neonates—that is, neonates born before 37 weeks of gestation. Preterm births are a major contributing factor to many deaths in children under five, with a larger percentage of deaths occurring during the neonatal era. The study was a prospective observational cohort study carried out at DDU Hospital in New Delhi in the neonatal intensive care unit of the pediatrics department. While term neonates had a mean gestation distribution of 38.64 weeks, late preterm newborns had a mean distribution of 35.39 weeks. The distribution of mean birth weight was 2.35 (±0.48) and 3.04 (±0.43) kg. Males were seen often in both research groups. The distribution of hypoglycemia among the study groups showed a significant difference, with late preterm infants having a higher incidence of the condition. The rate of post-resuscitation care varied significantly as well, with late preterm infants needing greater attention. A statistically significant increase was observed in the incidence of respiratory distress in late preterm newborns. Compared to the other group, late preterm infants had a higher prevalence of jaundice and sepsis. The study finds that compared to term newborns, late preterm infants had a higher risk of morbidity. To have a better understanding of these children's neonatal outcomes, more research is required.
