OBJECTIVE: to identify factors related to infant mortality in Foz do Iguagu, State of Paraná, Brazil. METHODOLOGY: a case-control study was conducted using secondary data obtainedfrom Brazil's Live Birth Information System and Mortality Information System; the study cases were children who died in 2007 before reaching one year; for each case, the authors defined as controls two children born of the same sex, in the same hospital, and still alive; multivariate analysis was performed with logistic regression. RESULTS: there were 69 cases and 138 controls; gestational age less than 37 weeks, low birth weight, children with congenital anomalies and Apgar score less than 7 at five minutes were considered risk factors, with odds ratios of 5.96 (CI_95%: 1.35-26.4), 4.32 (CI_95%: 1.14-16.4), 7.87 (CI_95%: 2.0-30.9) e 4.44 (CI_95%: 1.21-16.2), respectively. CONCLUSION: excluding congenital anomalies, the risk factorsfor infant mortality identified in Foz do Iguagu are related to the supply and quality of health services, especially in its neonatal component.

Keywords : infant mortality; risk factors; perinatal mortality; case-control studies; prematurity; congenital anomalies.
