Abstract

Abstract Background Pre-exposure prophylaxis (PrEP) is a crucial HIV prevention strategy for high-risk populations like female sex workers (FSWs). Understanding factors influencing PrEP acceptability and willingness to use is vital for effective implementation. This study assessed PrEP acceptability and willingness to use among FSWs in Lagos State, Nigeria. Methods We conducted a cross-sectional mixed-methods study among 310 FSWs in Lagos from June to August 2023. Quantitative data, collected using pre-tested, semi-structured questionnaires, were analysed with descriptive and inferential statistics. For the qualitative component, seven in-depth interviews (IDIs) were conducted, and data were thematically analysed. Results The mean age of respondents was 26.8 ± 4.31 years. PrEP acceptability and willingness to use were 68% and 80%, respectively. Acceptability was significantly associated with religion (p = 0.014), ethnicity (p = 0.002), age at sex work initiation (p = 0.003), number of clients per month (p = 0.007), and PrEP knowledge (p < 0.001). Specifically, lower acceptability was linked to Islamic religion, minority ethnicities (non-Igbo/Yoruba), early or late sex work initiation, and poor knowledge of PrEP. Willingness to use PrEP was also significantly associated with religion, ethnicity, and knowledge of PrEP. Poor knowledge (AOR = 0.40, CI: 0.22–0.73) and traditional religion (AOR = 0.06, CI: 0.00–0.56) significantly reduced willingness. Qualitative findings from IDIs revealed a preference for injectable PrEP, openness to accessing PrEP through health centres, and concerns about side effects. Conclusions PrEP is generally acceptable among FSWs in Lagos State, with high willingness to use. However, sociocultural and knowledge-related factors profoundly shape the uptake. Tailored, culturally sensitive education and service delivery strategies are essential to increase PrEP use among Nigeria's most vulnerable populations.

Understanding PrEP acceptability and willingness to use is critical to scaling prevention in this population. This study examined factors associated with PrEP acceptability and willingness to use among PrEP-naïve FSWs in Lagos State, Nigeria. Methods A cross-sectional study was conducted between June and August 2022 among 310 FSWs recruited from 24 hotspots across four local government areas in Lagos State using a multistage sampling design. Data were collected with a semi-structured quantitative questionnaire. Analyses were restricted to 223 participants who had never used PrEP. Bivariate analyses (Wilcoxon and Kruskal–Wallis tests) identified potential predictors, which were entered into separate multivariable linear regression models for PrEP acceptability and willingness scores. Non-standardised coefficients ( b ) are reported. Results Participants had a mean age of 26.19±4.11, and most (90%) had completed secondary education. In the final multivariable model for PrEP acceptability (adjusted R² = 0.264, p < 0.001), higher PrEP knowledge (b = 0.10, p = 0.006), Islamic religion (b = 1.94, p = 0.002), non-majority ethnic group (Others: b = 1.87, p = 0.003), and higher education (b = 2.46, p = 0.009) was independently associated with greater acceptability. For willingness to use PrEP (adjusted R² = 0.228, p < 0.001), higher PrEP knowledge (b = 0.12, p = 0.019) was associated with increased willingness, while later entry into sex work (b = -0.45, p < 0.001) was associated with reduced willingness. There was a marginal trend toward reduced willingness with increasing age (b = −0.19, p = 0.055). Conclusion Among PrEP-naïve FSWs in Lagos, PrEP knowledge emerged as a key correlate of both acceptability and willingness, while education, religion, and ethnicity were primarily associated with cognitive acceptability, and age-related factors influenced willingness. Interventions that improve PrEP knowledge and incorporate age-, literacy-, and sex-work–entry considerations may strengthen both acceptability and willingness among FSWs.
