Correlation between gestational age and incidence of hyperbilirubinemia in neonates

The incidence of hyperbilirubinemia in neonates is a significant concern worldwide, with potential implications for morbidity and mortality. This study aims to investigate the correlation between gestational age and the occurrence of hyperbilirubinemia in neonates. Secondary data were collected from the Neonatal Intensive Care Unit of Buleleng Regional Hospital from October 2022 to March 2024. The study employed an observational-analytical design with a cross-sectional approach. Pearson correlation analysis examined the relationship between bilirubin levels and gestational age. The results revealed a negative linear correlation between neonatal bilirubin levels and gestational age, indicating a higher risk of elevated bilirubin levels in preterm neonates. The majority of neonates included in the study were preterm (72.3%), with 98.3% experiencing hyperbilirubinemia. This study contributes valuable insights into the relationship between gestational age and hyperbilirubinemia in neonates, particularly in resource-limited settings. Early identification of at-risk neonates and appropriate interventions are crucial for preventing complications associated with hyperbilirubinemia.
