Pre-exposure prophylaxis use among cisgender and transgender adult entertainment workers in Brazil

Adult entertainment work may be associated with increased vulnerability to sexually transmitted infections, particularly HIV. In Brazil, pre-exposure prophylaxis (PrEP) for HIV infection has been available through the Brazilian Unified Health System (SUS) since November 2017, representing a significant advancement in public sexual health policy. The objective of this study was to understand the individual and social determinants that promote PrEP use among adult entertainment workers. This was a cross-sectional, analytical, and quantitative study. A multivariate modeling approach was employed to identify factors independently associated with PrEP use. The study included 254 adult entertainment workers using oral PrEP through the SUS, predominantly young adults (141; 55.5%), SUS users (248; 97.6%), single (213; 83.9%), non-white (142; 55.9%), cisgender (148; 58.3%), and heterosexual (152; 59.8%). Factors independently associated with greater PrEP use included having adult entertainment as the main source of income (aPR: 2.69; 95% CI: 1.86–3.95), prior use of PEP (aPR: 2.49; 95% CI: 1.63–3.81), undergoing any type of health treatment (aPR: 1.56; 95% CI: 1.15–2.12), and having a history of STIs (aPR: 1.51; 95% CI: 1.10–2.08). Conclusion: PrEP use in this population was strongly influenced by structural and contextual factors, indicating that the availability of the technology alone does not ensure its effectiveness.
