Improving HIV Prevention for Key Populations in Nigeria: Insights on Access, Barriers, Stigma, and Service Utilization

Background and Objective Human immunodeficiency virus and acquired immunodeficiency syndrome (HIV/AIDS) remains a significant public health challenge globally, with key populations (KPs) such as female sex workers (FSWs), men who have sex with men (MSM), and people who inject drugs (PWIDs) being disproportionately affected. Despite the availability of various HIV prevention services, including pre-exposure prophylaxis (PrEP) and community-based antiretroviral therapy (ART), the willingness of KPs to access these services remains a critical concern. This study aims to assess the prevalence of HIV and the willingness to access HIV preventive services among KPs in three selected local government areas (LGAs) in Nigeria. Methods A cross-sectional study was conducted in 2023 across three LGAs, Gwale, Fagge, and Tarauni, in Kano State, Nigeria, using a snowball sampling technique. A total of 1,320 participants, recruited from brothels and nightclubs, were tested for HIV using self-test kits. Willingness to access HIV services was assessed using a structured questionnaire. Data were analyzed using descriptive statistics and binary logistic regression. Results The overall HIV prevalence among KPs was 10.8%. MSM and PWIDs exhibited higher HIV prevalence rates compared to FSWs. Willingness to access HIV preventive services was recorded at 57.7%, with significant influences from geographical location and sexual practices. Participants from Tarauni were more willing to access services, and those engaging in vaginal sex were more likely to seek preventive services. HIV self-testing had a high uptake of 95.9%, while PrEP uptake was 68.0%. Major barriers included stigma, lack of comprehensive services, and limited knowledge of service providers. Conclusion and Global Health Implications This study highlights the critical need for targeted interventions addressing the specific barriers faced by KPs in these regions. Enhancing service accessibility and addressing stigma is essential for reducing HIV transmission and achieving epidemic control in Nigeria by 2030.
