History of previous infant death [OR 13.02 (95% CI 1.24-131.2)], premature rupture of membranes [OR 3.46 (95% CI 1.28-10.36)], Low birth weight [OR 3.12 (95% CI 1.42-8.48)], Prematurity [OR 2.78 (95% CI 1.09-7.12)] and domestic violence during pregnancy [OR 11.37 (95% CI 1.32-137.11)] were identified as significant risk factors for neonatal mortality in the current study.
