Abstract:
Background: Pre-exposure prophylaxis (PrEP) is a highly effective preventive measures against HIV infection but its success is strongly based on adherence, which in turn depends on willingness to use. This study is aimed at assessing the level of awareness and willingness to use PrEP to prevent HIV infection among female sex workers (FSWs) in Anambra State, Nigeria, and to identify factors that influence willingness to use PrEP.
Methodology: The study was a cross-sectional survey involving 265 brothel-based FSWs recruited through snowballing technique. A structured questionnaire was used to collect relevant information on demographic characteristics, awareness of HIV/AIDS and transmission route, attitudes/behavior related to HIV/AIDS, and awareness of and willingness to use PrEP. Univariate and bivariate analyses with Chi square test (with Odds ratio and 95% confidence interval) was used to determine association of socio-demographic and predictive factors with willingness to use PrEP. Statistical significance was considered when p value was less than 0.05.
Results: Of 265 FSW respondents, only 81 (31.2%) have heard of PrEP, 10 (3.9%) indicated they have previously used PrEP while 91.0% indicated willingness to use PrEP. Univariate analysis showed that FSWs in Onitsha had a significantly higher odds (OR=28.6, 95% CI=1.718-476.82, p=0.0006) while those from Awka had a significantly lower odds (OR=0.184, 95% CI=0.0704-0.1812, p=0.0004) of willingness to use PrEP. Also, FSWs with monthly income less than 18,000 Naira had a lower odd of willingness to use PrEP (OR=0.3980, 95% CI=0.1593-0.9945, p=0.08). Bivariate analysis shows that FSWs who wish to have more knowledge of HIV/AIDS had higher odd of willingness to use PrEP than those who did not wish to have more knowledge (OR=4.235, 95% CI=1.577–11.374, p=0.0066). Similarly, FSWs who are worried of being discriminated against have a lower odd of willingness to use PrEP than those who are not worried of being discriminated against (OR=0.3921, 95% CI=0.1582-0.9718, p=0.0439).
Conclusion: Our study showed low awareness but high willingness to use PrEP among FSWs in Anambra State, Nigeria. Cost, HIV/AIDS knowledge and fear of discrimination are significant predicting factors of willingness to use HIV PrEP and should be considered when formulating PrEP policy. Adequate enlightenment on PrEP should be emphasized among FSWs.
