Viral Load Suppression After Intensive Adherence Counselling Among Previously Non-Suppressed Adolescents and Young...

Viral load suppression remains suboptimal among adolescents and young people living with HIV in Uganda (AYPLHIV). Although Intensive Adherence Counselling is recommended for individuals who remain virally non-suppressed while on antiretroviral therapy, its contribution to suppression among AYPLHIV is not well understood. This study aimed to determine the level of viral load suppression achieved following intensive adherence counselling among previously non-suppressed AYPLHIV in east central Uganda.

We conducted a sequential explanatory mixed methods study among 580 participants aged 10-24 years receiving care at 32 health facilities. Quantitative data were abstracted covering a five-year period from 2019-2024. Suppression levels and subgroup differences were assessed using chi-square tests. A qualitative study was conducted with 12 purposively selected participants and thematic analysis were guided by the Capability, Opportunity, Motivation and Behavior framework.

Participants had a median age of 16.4 years and a median ART duration of 4 years. Overall, out of the 580 participants, 313 (53.9%) achieved viral load suppression after counselling. Participants living more than 5 km compared to less than 5km from a health facility (p=0.003) and those counselled by counsellors rather than nurses (p<0.001) had significantly higher suppression level. Lower suppression level was observed among participants who had not disclosed their HIV status versus those who disclosed (p=0.011) and those reporting fear or stigma compared to those not reporting (p=0.010). Qualitative findings indicated that understanding the purpose and benefits of intensive adherence counselling (Capability), financial barriers and provider interactions (Opportunity), and non-disclosure (Motivation) influenced suppression outcomes among AYPLHIV.

IAC resulted in modest improvements in VL suppression among AYPLHIV. Low retention and contextual barriers, including distance, stigma and non-disclosure, limited its effectiveness. Tailored IAC strategies addressing subgroup-specific barriers are needed to improve VL suppression.
