Objective. To determine the incidence, risk factors and survival of newborn with extremely low weight in the Hipolito Unanue Hospital, in Tacna. Patients and Method. A retrospective, analytical, casecontrol study. All live births of singleton pregnancy with birth weight less than 1,000 g, born during the years 20002014 in the Hipolito Unanue Hospital in Tacna, Peru, were analyzed. The incidence and survival per 100 live births was evaluated and risk factors were analyzed. The cases were all infants less than 1000 g, and controls, all newborns weighing between 2500 and 3999 g. The odds ratio (OR)was calculated with a confidence interval of 95%. The information was obtained from the database of Perinatal Information System. Results. 49979, 191 live births were born with less than 1000 grams of weight, the incidence of infants of extremely low birth weight was 0,38 x 100 live births and survival 19,7%, with upward trends. The associated risk factors were significantly: single mother (OR = 1,9), no or inadequate prenatal care (OR = 11,6), presence of maternal pathologies (OR = 2,5) and preterm delivery (OR = 24,9), premature rupture of membranes (OR = 8,1), abnormal amniotic fluid (OR = 7,5), third trimester bleeding (OR = 5,3) and hypertensive disease of pregnancy (OR = 4,2). Conclusion. The newly born extremely low birth weight Hipolito Unanue Hospital in Tacna has low incidence and survival, and its risk factors lack or inadequate prenatal and maternal pathologies.
