摘要：The objective of this study was to evaluate the importance of prenatal care in the prophylaxis of mother-to-child transmission of HIV (MTCT). This is a retrospective cohort study at the Perinatal Center of the State University of Rio de Janeiro. The study population consisted of 323 HIV-positive pregnant women and their babies, who were born at the maternity hospital from 2007 to 2018. The pregnant women were separated according to the moment of diagnosis of HIV infection: Group 1: diagnosis during pregnancy and, Group 2: diagnosis prior to pregnancy. Data was collected from hospital records of pregnant women and newborns. The variables used were data on pregnancy, delivery, puerperium, and NB follow-up. There was no significant difference regarding marital status, color, and age of the pregnant women. The beginning of prenatal care after the first trimester of pregnancy occurred in 64.1% of group 1 and in 43.8% of group 2. Of the pregnant women who discovered the diagnosis during pregnancy, 82.4% used ART for more than 4 weeks. In the cases of contaminated newborns (1.2%), the number of prenatal visits was < 6 in three of the four cases, only one of the four mothers used ART for the necessary time, and the viral load in the third trimester was higher than 1,000 copies/mL, in three cases and, unknown in one case. Prenatal care has been a significant time for HIV diagnosis and early initiation of MTCT, with good perinatal outcomes.
