Abstract A case-control study was carried out to estimate risk factors for perinatal mortality in a referral hospital for high-risk pregnancies in Curitiba-PR. Sociodemographic, maternal, pregnancy and concept characteristics data were obtained from the hospital records of 316 cases and 316 controls from 2013 to 2017. A hierarchical multiple logistic regression analysis was performed, remaining in the final model variables with p < 0.05. The results show an increased risk of perinatal death in mothers with blood type B (OR = 2.82; 95%CI: 1.07-7.43), who did not undergo prenatal care (OR = 30.78; 95%CI: 4.23-224.29), fetuses with congenital malformations (OR = 63.90; 95%CI: 27.32-149.48), born under 28 (OR = 24.21; 95%CI: 1, 10-531.81) and between 28-31 weeks of gestation (OR = 6.03; 95%CI: 1.34-27.17) and birth weight below 1,000g (OR = 51.94; 95%CI: 4.31-626.46), between 1,000-1,499g (OR = 11.17; 95%CI: 2.29-54.41) and between 1,500-2,499g (OR = 2.75; 25-6.06). Concepts of pregnancies with premature outcome, low birth weight and the presence of congenital malformations are the main risk factors for perinatal death. On the other hand, adequate prenatal care is an important protective factor. casecontrol case control highrisk high CuritibaPR. CuritibaPR Curitiba PR.

Resumo Estudo caso-controle com o objetivo de estimar os fatores de risco da mortalidade perinatal em um hospital de referência para gestações de alto risco em Curitiba-PR. Os dados de características sociodemográficas, maternas, da gestação e do concepto foram obtidos dos prontuários hospitalares de 316 casos e 316 controles do período de 2013 a 2017. Foi realizada análise de regressão logística múltipla hierarquizada, permanecendo no modelo final variáveis com p < 0,05. Os resultados mostram aumento do risco de óbito perinatal em mães com tipo sanguíneo B (OR = 2,82; IC95%: 1,07-7,43), que não realizaram pré-natal (OR = 30,78; IC95%: 4,23-224,29), conceptos com malformações congênitas (OR = 63,90; IC95%: 27,32-149,48), nascidos com menos de 28 (OR = 24,21; IC95%: 1,10-531,81) e entre 28-31 semanas de gestação (OR = 6,03; IC95%: 1,34-27,17) e peso ao nascer abaixo de 1.000g (OR = 51,94; IC95%: 4,31-626,46), entre 1.000-1.499g (OR = 11,17; IC95%: 2,29-54,41) e entre 1.500-2.499g (OR = 2,75; IC95%: 1,25-6,06). Conceptos de gestações com desfecho prematuro, baixo peso ao nascer e presença de malformações congênitas são os principais fatores de risco para o óbito perinatal. Em contrapartida, a assistência pré-natal adequada é importante fator de proteção. casocontrole caso controle CuritibaPR. CuritibaPR Curitiba PR.
