Introduction: The World Health Organization (WHO) defines low birth weight (LBW) as arnnewborn weighing is less than 2,500 grams. The UNICEF (united nations international childrenâ€™srnemergency fund) and WHO estimates indicate that one in seven live births globally sufferedrnfrom low birth weight in 2015. The prevalence of low birth weight varied widely across regionsrnfrom 7.2 per cent in more developed regions to 17.3 per cent in Asia, in Ethiopia neonatalrnmortality accounts 30 per 1000 live births from 55 per 1000 live birth children deaths, LBWrnneonates were responsible for most deaths. rnObjective: To assess survival status and to identify predictors of mortality of low birth weightrnneonates admitted in selected governmental hospitals of Addis Ababa, Ethiopia. rnMethods: A retrospective cohort study will employed among 404 neonates with LBW admittedrnto neonatal intensive care unit (NICU) of selected four governmental hospitals in Addis Ababa,rnbetween January 2018 and January 2021. The data will be collected from randomly selectedrnrecords from each year. Data will be entered to Epi-Data version 7.2.2.6 and exported to SPSSrnVersion 24 for analysis. The Kaplan Meier survival curve will used to estimate the cumulativernsurvival time. Log rank tests will used to compare probability of hazard among variables. Bivaraiternrnand multivariate Cox proportional hazards models will used to identify predictorrnvariables and variables having p value < 0.05 will considered as statistically significant. rnBudget: This study will require a total budget of 32,640 birr with 10% contingency added.
