Data were collected from October 2016 to September 2021 from all neonates with 35 weeks of gestational age or more with EOS and randomly collected from neonates with 35 weeks of gestational age or more without EOS. The associated factors of EOS were shown as an odds ratio by multivariate analysis of binary logistic regression.Results: In this study, 595 neonates were enrolled and divided into 2 groups – EOS group (193 neonates) and non-EOS group (402 neonates). The incidence rate of EOS was 21.23/1000 live births, comprising 2 culture-positive EOS neonates (0.22/1000 live births) and 191 culture-negative EOS neonates (21/1000 live births). The common clinical manifestations in the EOS group were respiratory distress (157 neonates, 81%), temperature instability (43 neonates, 22.3%) and poor feeding (39 neonates, 20.2%). Statistically significant relationship (p-value < 0.05) was found in prolonged rupture of membrane (OR 11.7, 95% CI: 2.54– 53.88), low birth weight (OR 2.3, 95% CI: 1.25– 4.4) and normal Apgar score at 5 minutes after birth (OR 0.5, 95% CI: 0.31– 0.71).Conclusion: Our study shows that the incidence rate of culture positive EOS in late preterm and term is very low. EOS was significantly associated with prolonged rupture of membrane and low birth weight whereas lower rate of EOS was significantly associated with normal Apgar score at 5 minutes after birth. Efforts to recognize these factors early and effectively resuscitate neonates may reduce and prevent neonatal morbidity and mortality.Keywords: prolonged rupture of membrane, low birth weight, term infant, preterm infant
