| Rocha et al., 2025 Brazil Cross-sectional study |
To analyze indicators related to prenatal care using information from the 2013 and 2019 editions of the National Health Survey. |
Between 2013 and 2019, prenatal care coverage remained high and stable (>95.0%), HIV testing increased by about 20.0%, reaching almost 100% (99.3%), while early initiation of prenatal care, the minimum number of consultations, and referral for delivery showed little progress, despite the high coverage of these indicators (>80.0%). |
| Lima et al., 2025 Brazil Retrospective cohort |

| Miranda et al., 2023 Brazil Descriptive study |
To assess trends in vertical transmission in Brazil over the last decade (2011-2021). |
Between 2011 and 2021, 85,470 pregnant women and 3,781 children were diagnosed with HIV. The incidence rate among pregnant women was 2.5 per 1,000 live births.

To describe the subnational certification process for elimination of vertical transmission of HIV and/or syphilis, identifying challenges, barriers and opportunities. |
By 2022, 43 municipalities with more than 100,000 inhabitants had been subnationally certified for HIV, syphilis and/or hepatitis B, totaling 24.6 million people, especially in the Southeast and South regions. Despite integration between surveillance and care, shortcomings were revealed in the implementation of electronic medical records and in the recording of prenatal testing. |
| Aguiar et al., 2023 Rio Branco, Acre Retrospective cohort |

| Leal et al., 2020 Brazil Hospital-based national study |
To examine regional inequalities in access to and quality of prenatal and childbirth care in public health services in Brazil and their association with perinatal health. |
Childbirths were concentrated in adolescents with low levels of education and lower economic status, especially in the North and Northeast regions (p-value<0.001). Prenatal care coverage was 98.5%, but only 56.5% of pregnant women started prenatal care in the first trimester in the North (46.0%) and Northeast (52.2%). 72.1% of the women had six or more prenatal visits. HIV testing occurred in 52.1% of visits. |
| Freitas et al., 2019 Brazil Descriptive study |
To assess the social determinants of access to HIV and VDRL testing during pregnancy in Brazil – National Program for Improving Access and Quality of Primary Care. |
Fewer than six prenatal visits were associated with low human development indices (HDI) (≤0.694), low schooling levels (<8 years), and being income transfer programs beneficiaries. Absence of HIV/syphilis testing was related to low HDIs and greater social inequality (Gini≥0.521). |
| Freitas et al., 2019 Brazil Descriptive study |
To evaluate the factors associated with HIV and syphilis testing not being performed during pregnancy in primary health care in Brazil. |
Absence of testing was more frequent among White women aged 15-19 years, with low education and social program beneficiaries (PR 1.43; 95%CI 1.19; 1.72). Fewer than six prenatal visits were associated with low education (<8 years) (PR 1.31; 95%CI 1.19; 1.45; p-value<0.001) and receiving social benefits (PR 0.80; 95%CI 0.72; 0.88; p-value<0.001). |
| Hofer et al., 2019 Rio de Janeiro Retrospective cohort |
To assess association between geographic distance, prenatal care coverage and vertical transmission of HIV in Rio de Janeiro. |
Living more than 9.5 km from the place of birth significantly reduced the likelihood of receiving prenatal care (OR 0.35; 95%CI 0.18; 0.68). Absence of prenatal care was more prevalent among infected babies (38.1%) compared to uninfected babies (27.3%). |
