ABSTRACT
Female sex workers (FSWs) are among the key populations (KP) prioritized for comprehensive HIV programming in Kenya. Retention in the program is critical for prevention of HIV acquisition and transmission among FSWs and their sexual partners. We conducted a retrospective cohort analysis of data collected from FSWs enrolled between October 2016 and September 2017 at seven drop-in centers (DICs) in Nairobi, Kenya, to assess factors associated with retention in HIV prevention and treatment services. We found a 3- and 12- month retention of 24% and 17%, respectively. FSWs aged 20-34 years old were less likely to be retained compared to those 50 years or older. FSWs enrolled in a DIC located in their sub-county of residence or reporting ever using HIV pre- or post-exposure prophylaxis were more likely to be retained. Engaging young FSWs to identify strategies to enhance retention should be prioritized. Strengthening the referral system across DICs may provide opportunities to enhance retention in facilities closer to their residence. Implementation research is needed to gain an additional understanding of the health services needs and preferences among FSWs to optimize retention for this population.
