Syphilis Testing Among Female Prisoners in Brazil: Results of a National Cross-sectional Survey.

Brazil has the third largest prison population in the world and is also experiencing a high and rising rate of syphilis infection. To establish the gaps in syphilis testing, we examined data from a nationally representative sample of incarcerated women in Brazil. Data originated from a cross-sectional survey designed to represent all regions of Brazil (N = 1,327). Data were collected by Audio Computer-Assisted Self-Interview, including variables in several blocks or domains. 49.2% had a lifetime history of being tested for syphilis. Increased likelihood of syphilis testing was significantly associated with completed elementary education (odds ratio ajustado [AOR] 1.75, 95% confidence interval [CI] 1.28-2.40), completed high school or more (AOR 2.04, 95% CI 1.36-3.06), income below minimum wage (AOR 1.46, 95% CI 1.10-1.94), homelessness (AOR 1.83, 95% CI 1.21-2.76), having heard of the female condom (AOR 1.92, 95% CI 1.25-2.95), received a condom in prison (AOR 1.56, 95% CI 1.11-2.21) or in public health services (AOR 1.50, 95% CI 1.13-1.98), lifetime history of pregnancy (AOR 2.55, 95% CI 1.67-3.89), had a gynecological examination (AOR 1.73, 95% CI 1.05-2.83), and perceived they had some chance (AOR 1.61, 95% CI 1.17-2.20) or a big chance (AOR 1.89, 95% CI 1.31-2.73) that they were likely to have been infected with HIV before entering prison.
