Abstract Objectives: to determine the incidence of peri-intraventricular hemorrhage (PIVH) and the risk factors in newborns weighing <1,500 g and/or gestational age <33 weeks. Methods: a prospective cohort type study on premature newborns admitted to the type II neonatal intensive care unit at the Sistema Único de Saúde (SUS) (Public Health System) from January/2019 to December/2022. The dependent variable was PIVH, with determination of its incidence and associated risk factors. The project was approved by the Research Ethics Committee. Results: a total of 503 neonates participated and the incidence of PIVH was 32.4%. The risk factors were: immediate clamping of the umbilical cord (p=0.017; RR= 1.089; 95%CI=1.015-1.167), vaginal delivery (p=0.001, RR= 1.110; 95%CI= 1.041-1.183) and surfactant use (p<0.001; RR= 1.163; 95%CI= 1.092-1.239). Conclusion: the incidence of PIVH was high and was associated with immediate clamping of the umbilical cord, vaginal delivery and surfactant use, risk factors that can be modified by good perinatal care practices.
