BackgroundTranswomen (also known as transgender women) are disproportionately affected by all forms of gender-based violence (GBV). The high prevalence of physical, sexual and emotional violence not only predisposes transwomen to HIV infection but also limits the uptake/access to HIV prevention, care, and treatment services. Despite the high prevalence of HIV infection and GBV among transwomen, there is limited evidence on how GBV affects the uptake and utilisation of HIV prevention, care, and treatment services. Therefore, this qualitative study explored how GBV affects uptake and utilisation of HIV prevention, treatment, and care services among transwomen in the Greater Kampala Metropolitan Area (GKMA), Uganda.MethodsThis participatory qualitative study was conducted among transwomen in the GKMA. A total of 20 in-depth interviews, 6 focus group discussions, and 10 key informant interviews were conducted to explore how GBV affects the uptake and utilisation of HIV prevention, treatment, and care services among transwomen. Data were analysed using a thematic content analysis framework. Data were transcribed verbatim, and NVivo version 12 was used for coding.ResultsAt the individual level, emotional violence suffered by transwomen led to fear of disclosing their HIV status and other health conditions to intimate partners and healthcare providers respectively; inability to negotiate condom use; and non-adherence to antiretroviral therapy (ART). Sexual violence compromised the ability of transwomen to negotiate condom use with intimate partners, clients, and employers. Physical and emotional violence at the community level led to fear among transwomen traveling to healthcare facilities. Emotional violence suffered by transwomen in healthcare settings led to the limited use of pre-exposure prophylaxis and HIV testing services, denial of healthcare services, and delays in receiving appropriate care. The fear of emotional violence also made it difficult for transwomen to approach healthcare providers. Fear of physical violence such as being beaten while in healthcare settings made transwomen shun healthcare facilities.ConclusionThe effects of GBV on the uptake and utilisation of HIV prevention, care, and treatment services were observed in individual, community, and healthcare settings. Across all levels, physical, emotional, and sexual violence suffered by transwomen led to the shunning of healthcare facilities, denial of healthcare services, delays in receiving appropriate care, and the low utilisation of post-exposure prophylaxis, and HIV testing services. Given its effects on HIV transmission, there is a need to develop and implement strategies/ interventions targeting a reduction in GBV. Interventions should include strategies to sensitize communities to accept transwomen. Healthcare settings should provide an enabling environment for transwomen to approach any healthcare provider of their choice without fear of experiencing GBV.
