Women in labour were screened for antibodies against HIV-1/2, T. pallidum and HCV. Antigen detection was used to diagnose HBV infections. Sociodemographic data were also collected. The seropositivity rate and respective CIs were estimated at a level of 95%. Multivariable logistic regression models were performed to explore the association between the studied infections and sociodemographic factors.Results In 11.8% of the parturients (95% CI 9.3 to 14.9), at least one infection was detected. HBV infection was the most common (8.6%), followed by HIV infection (3.0%) and syphilis (1.0%). Coinfection with HBV and HIV was observed in two parturients (0.4%) and HBV, HIV and T. pallidum were all detected in one parturient (0.2%). No HCV infection was detected. For each additional year of formal education, pregnant women had a 10.0% lower chance of being infected with HBV (adjusted OR=0.900, 95% CI 0.816 to 0.992).Conclusions This study is one of the few reports contributing for the knowledge of some sexually transmitted infections epidemiology in Angola. The seropositivity rate of the studied infections is of concern, especially the high endemicity of HBV. There is a need for a stronger commitment and further research to design cost-effective public health and clinical interventions to improve the situation.
