Abstract Background Female sex workers (FSWs) have been identified as a core group in the transmission of HIV and other sexually transmitted infections (STIs). Young FSWs are particularly more vulnerable to HIV due to the combination of vulnerabilities associated with their youth and the sex work they engage in. This study aims to give more insight into HIV prevalence and sexual risk behaviour of young FSWs in Nigeria, by focusing on the differences between BB and NBB young FSWs. Methods Data was obtained from the Nigeria Integrated Biological and Behavioural Surveillance Survey (IBBSS) for high-risk groups conducted in 2010. IBBSS is a quantitative survey conducted amongst identified high-risk sub populations within Nigeria. HIV prevalence and risk behaviour data for young BB and NBB FSWs aged 15–24 years for nine states was extracted and analysed. Results A total of 1796 FSWs aged 15–24 years were interviewed during the survey, 746 (41.5%) were BB while 1050 (58.5%) were NBB. The HIV prevalence was higher among BB FSWs compared to the NBB FSWs (21.0% vs. 15.5%). BB FSWs reported less condom use with boyfriends and casual partners than NBB FSWs (26.3% vs. 45.5%) and (55.1% vs. 61.1%) respectively while risk of HIV infection due to injecting drug use was higher in NBB compared to BB FSWs (6.6% vs. 1.2%). Conclusion Existing and future interventions on HIV prevention should focus on empowering young FSWs with innovative and sustainable approaches aimed at improving their health and wellbeing.

There is growing support of male involvement in reproductive health and the integration of voluntary vasectomy services into national family planning programs in lower resource contexts; yet, the prevalence of women of reproductive age who rely on vasectomy in African countries such as Nigeria, is less than 1 percent. This review was conducted to gain a broader understanding of current sociocultural and health systems' conditions that need to be addressed to expand the integration and acceptability of vasectomy as an option for family planning in Nigeria. To explore this, a scoping of existing literature on vasectomy in Nigeria between 2009 to 2021 was conducted. The review focused on qualitative studies and grey literatures. The findings reveal that there is a strong awareness of vasectomy among men in Nigeria. Yet, several factors such as fear and religious and cultural beliefs prevent men from having the same confidence in vasectomy as they have in female biomedical methods. These findings have implications for future family planning policies, strategies and programmes in the country.

Background: The HIV prevalence among female populations involved in sex work in Nigeria has heightened interest in HIV prevention programming for this sub-population with brothel-based female sex workers (BB FSWs) having a prevalence of 27.4%, six times higher than the prevalence in the general population., Methods/design: The clusters in the randomized pilot trial will be brothels and female sex workers (FSWs) residing in the brothels will be the participants of the study. The participants will receive free condom distribution as well as HIV prevention messages on condom use and negotiation skills to increase self-efficacy in handling social and gender power plays within their environment. Twelve brothels will be randomized into experimental and control conditions with a minimum total sample size of 200 participants. Recruitment of participants will be carried out from within the brothels. The control condition will receive a standard intervention consisting of a minimum of six interactive sessions with peer educators (PE) engaging their peers through group discussions and one on one interaction using pre-designed HIV prevention messages. The experimental condition will receive the standard intervention as well as interactive sessions with the brothel leadership (chairladies and brothel managers) to facilitate consistent condom use and appropriate condom use policies, conditions, and messaging. Both interventions will be delivered over a maximum period of 16 weeks, and male and female condoms will be distributed during the intervention. Quantitative assessments will be carried out at baseline and at 16 weeks follow-up, and the pilot findings will inform feasibility of and sample size estimation for a phase III trial. The primary outcomes measured are recruitment rate attrition rate and adherence to the intervention. Consistent condom use outcomes by FSWs within the brothel with all partner types and enhanced self-efficacy for condom negotiation with all partner types will be the primary outcomes for the main study, and the feasibility of their measurement will be determined in this pilot trial., Discussion: The manuscript describes the protocol for a pilot study to determine the feasibility of a behavioral intervention to improve consistent condom use among BB FSWs. The results of this pilot will inform a larger intervention for HIV prevention for this target group in Nigeria., Trial Registration: The Institutional Review Board (IRB) of the Institute of Human Virology, Nigeria; Protocol Number NHREC/10/15/2014a-026.
