Objectives. Describe the epidemiological characteristics of neonatal deaths in Peru. Materials and methods. Descriptive study based on notifications to the Perinatal and Neonatal National Epidemiological Surveillance Subsystem (PNNESS) made in 2011-2012. The capture-recapture method was used to calculate the registration of the notification and estimate the neonatal mortality rate (NMR) nationally and by regions. Responses were made to the questions: where, when, who and why the newborns died. Results. 6,748 neonatal deaths were reported to PNNESS, underreport 52.9%. A national NMR of 12.8 deaths/1,000 live births was estimated. 16% of deaths occurred at home and 74.2% of these were in the highlands region, predominantly in rural areas and poor districts. 30% died in the first 24 hours and 42% between 1 and 7 days of life. 60.6% were preterm infants and 39.4% were term infants. 37% had normal weight, 29.4% low weight, and 33.6% very low weight. Preventable neonatal mortality was 33%, being higher in urban and highland areas. 25.1% died of causes related with prematurity-immaturity; 23.5% by infections; 14.1% by asphyxiation and causes related to care during childbirth and 11% by lethal congenital malformation. Conclusions. Neonatal mortality in Peru is differentiated by setting; harms related to prematurity-immaturity dominated on the coast, while the highlands and jungle recorded more preventable neonatal mortality with a predominance of asphyxia and infections.
