Low engagement of key populations in HIV health services in Tanzania: analysis of community, legal and policy factors.

Introduction: key populations (KP) often face legal and social challenges that increase their vulnerability to HIV. These experiences include criminalization, higher levels of stigma and discrimination which negatively affect access to HIV services. This study aims to understand legal, community and policy factors affecting engagement of KP in HIV health interventions.

Methods: qualitative research key populations design involving a desk review and stakeholder's engagement. We reviewed program data from NACP on how KP access health services and then conducted three stakeholders' engagement meetings. Factors affecting access to health services by KP were documented. Data were organized using socio-ecological model (SEM).

Results: program data showed only 49% of the estimated KP accessed health services. Barriers to accessing health services at the interpersonal level included lack of social support and high-risk networks linked with risk behaviours. At the community, stigma and discrimination, limited engagement of influential leaders were noted. In health facilities, lack of trained staff to provide KP friendly services affected utilization of health services. At structural level, despite improvements, still various laws negated engagement of KP such criminalizing drug use, same sex, and sex work. Harassments and arrests further marginalize KP and makes access to health intervention harder.

Conclusion: engagement of key population into HIV health interventions was limited at multiple levels. The study recommends building capacity on KP friendly services for communities, law enforcement and health care providers, further engagement of communities including religious leaders on KP issues and implementing differentiated service delivery models for KP.
