This study tests scalable interventions to improve 6-month retention in antiretroviral therapy (ART) programs for men living with HIV in sub-Saharan Africa who are not currently engaged in care.
Area of Science:
- Public Health
- HIV/AIDS Research
- Clinical Trials
Background:
- Men in sub-Saharan Africa exhibit lower initiation rates and higher disengagement from antiretroviral therapy (ART) programs compared to women.
- There is a critical need for scalable, male-specific interventions to improve engagement in HIV care for men.
Purpose of the Study:
- To evaluate the impact of different intervention intensities on 6-month retention in ART programs among men living with HIV who are disengaged from care.
- To assess the cost-effectiveness and safety of these interventions.
Main Methods:
- A programmatic, individually randomized, non-blinded, controlled trial involving men not currently engaged in ART care.
- Participants are randomized to low-intensity (one-time counseling), high-intensity (immediate outside-facility initiation), or stepped care arms.
- The primary outcome is 6-month retention in care, analyzed using intention-to-treat principles with binomial regression accounting for facility-level clustering.
Main Results:
- Primary outcome data on 6-month retention are pending analysis.
- Secondary outcomes including cost-effectiveness and adverse events will also be evaluated.
Conclusions:
- The findings are expected to provide crucial data for designing and implementing effective, scalable interventions to improve ART retention among men living with HIV in sub-Saharan Africa.
- Dissemination will occur through national/international forums and peer-reviewed publications to inform global health strategies.
