Abstract
Objective: To analyze the influence of sociodemographic characteristics on the number of prenatal consultations and how they influence maternal and neonatal outcomes. Methods: This is a cross-sectional and analytical study on the factors that influence and are influenced by the number of prenatal consultations that took place in 2017 in the municipalities of Bragança, Capanema and Viseu. The data were extracted from the basis of the Live Birth Information System (SINASC), in which descriptive and analytical statistics were performed. Results: A total of 4,279 live births were recorded in the municipalities of the study, 49% in Bragança, 26.7 % in Viseu and 24.3% in Capanema. They were associated with a statistically significant number of consultations: marital status in Viseu and Capanema; age 10 to 17 years in Capanema; schooling in all municipalities. They demonstrated an association (p <0.05) of the type of delivery in Bragança and Capanema; the length of pregnancy in all municipalities; the weight in Bragança and Viseu; and apgar in Capanema. Conclusion: A quality prenatal care can help in the early identification of pregnancy complications, contributing to the reduction of risks, both for the pregnant woman and for the fetus, making it essential for the promotion of maternal and neonatal health.
