Abstract / Summary
Background Viral load suppression (VLS) remains suboptimal among adolescents and youth living with HIV (AYLWH) in Malawi. Depressive symptoms may affect treatment adherence and HIV outcomes, but evidence is limited. We assessed the association between depressive symptoms and VLS among AYLWH using Malawi Population-based HIV Impact Assessment (MPHIA) 2020-2021 data. Methods We conducted a cross-sectional secondary analysis of AYLWH aged 15-24 years. VLS was defined as HIV RNA less than 200 copies/mL and depressive symptoms as a Patient Health Questionnaire-2 score of 3 or higher. Survey-weighted logistic regression assessed associations with VLS, adjusting for sex, education, residence, household wealth, alcohol use, Teen Club participation, and awareness of HIV-positive status. Findings Among 201 participants, viral-load results were available for 200; 137 (68.5%) achieved VLS. Six (3.0%) participants had depressive symptoms. Depressive symptoms were not associated with VLS in univariable analysis (OR 0.8, 95% CI 0.1-4.6; p=0.80) or multivariable analysis (aOR 0.3, 95% CI 0.1-2.4; p=0.28). Urban residence (aOR 0.2, 95% CI 0.1-0.5; p=0.0020) and unawareness of HIV-positive status (aOR 0.1, 95% CI 0.02-0.1; p<0.001) were associated with lower odds of VLS. Interpretation Depressive symptoms were not significantly associated with VLS, although their low prevalence and PHQ-2 limitations reduced precision. The findings highlight the importance of strengthening HIV-status awareness and addressing context-specific barriers to care among AYLWH. Funding This secondary analysis received no specific funding.
