THE PREVALENCE AND RISK FACTORS FOR HYPERBILIRUBINEMIA IN NEONATES

Background: Jaundice is very common in the neonatal period of life especially hyperbilirubinemia>12 mg/dl. Although it is not a major cause of mortality, it is an important cause of morbidity. So, assessment of the prevalence and risk factors of neonatal jaundice is very important.

Objectives: The objectives of the study were to estimate the prevalence,to identify the risk factors and to findout the association between hyperbilirubinemia with selected neonatal,maternal,environmental and socio demographic variablesand to identify the risk factors.

Methodology: This descriptive cross sectional survey study was conducted among 200 neonates of 37 completed weeks of gestation. Subjects were selected by using total enumerative sampling.Transcutaneous bilirubin was measured by bilirubinometer,clinical and demographic variables collected by using semi structured questionnaire and the risk factors were assessed by interview schedule.

Results:Research showed that most of neonates (81.5%) had Transcutaneous bilirubin level more than 12mg/dl, out of that (15% )subjects had elevated level of bilirubin 15- 20mg/dl. It is concluded that there is high prevalence of hyperbilirubinemia among neonates . It is evident that neonates developed hyperbilirubinemia by 48 to 72 hours. It is inferred that prevalence of hyperbilirubinemia was high at 72 hours (56.5%) after birth compared to 48 hours of birth (38%). There was a significant association between level of hyperbilirubinemia and family history of genetic diseases (P=0.003),parity (p=0.03, χ2=4.37),mode of conception(p=0.012, χ2=6.37), and gestational age(P=0.04),gender of the neonate (p=0.004, χ2=8.1)and duration of second stage of labour (p=0.026, χ2=7.27). The study revealed that the family history of genetic diseases (p=0.004),(OR=0.09) at level of significance 0.05,is a risk factor leads to hyperbilirubinemia.

Conclusion: Neonatal jaundice is a leading cause of hospitalisation in the first few weeks of life throughout the world.Though major complications may arise like kernicterus,encephalopathy and neural sequlae.Hence there is an exigent need for assessing the bilirubin value in the routine neonatal assessment.
