Objective: To evaluate the factors associated to perinatal mortality. Methods: A case-control study, in the period from 01/01/11 to 12/31/15 in a public maternity hospital in the South of Brazil. The group of cases includeds all deaths recorded from the 22nd week of gestation until the 6th full day of life of the newborn. The control group includes live births randomly collected, with a number equal to twice the total number of deaths, in the same period. The factors evaluated were maternal characteristics (age, ethnicity and schooling) and the characteristics of gestation (gestation type, gestational age, and type of delivery). Logistic regression models were used to calculate odds ratios to examine perinatal mortality, with a 95% confidence interval and significant values when p <0.05. Results: A total of 334 cases and 668 controls were selected. An increased risk of perinatal death was found in maternal age> 35 years, with odds ratio of 2.64 (95% CI: 1.05-6.62; p = 0.03); in mothers with schooling < 8 years of study with odds ratio of 2,12 (95% CI: 1.08 - 4.13, p = 0.03), and in those with multiple gestation in which the odds ratio was 7.41 (95% CI 1.37 40.03, p = 0.02). In the other items evaluated, no relation was observed with the increased risk of perinatal death. Conclusion: The factors associated with the an increased risk of perinatal mortality are maternal age greater than 35 years, schooling less than 8 years of study and multiple gestation.
