ABSTRACT Background: The World Health Organization (WHO) estimates the prevalence of preterm birth to be between 5% and 18% across 184 countries. Of the estimated 3 million neonatal deaths occurring globally each year, about 1 million are directly related to prematurity. Uganda has one of the highest preterm birth rates in the world estimated at 13.6 per 1000 live births and little was known about prevalence of preterm birth in Kiryandongo hospital. In order to realize a reduction in pre-term births, interventions that target the risk factors are paramount. Hence, this study was to explore the prevalence and risk factors of preterm birth in Kiryandongo general hospital. Methods: All mothers who had live births at Kiryandongo Hospital and their newborns were included in the study. Mothers were interviewed using a standard pretested questionnaire to identify factors associated with preterm birth. Data was analyzed using excel analysis package version 2016 and a pvalue < 0.05 was considered significant. Results: A total of 154 mother-baby pairs were enrolled into the study. The mean maternal age was 26±5 years while most mothers (83%) were married and had attained primary level of education or below (85%). The prevalence of preterm birth in this study was found to be 18.3% (95% CI of 14.1- 22.5). Parity ≥ 4, previous preterm birth, multiple gestation, pregnancy induced hypertension (PIH), antepartum hemorrhage (APH), prolonged preterm prelabor rupture of membranes (PPROM) and urinary tract infection (UTI) in pregnancy were all significantly associated with preterm birth (p=
