A Cluster-Randomized Controlled Trial of an Economic Strengthening Intervention to Enhance Antiretroviral Therapy Adherence among Adolescents Living with HIV

Abstract

We examined the impact of an economic empowerment intervention on ART adherence among ALHIV. We used data from 455 ALHIV, randomized into intervention, n = 111, and control n = 344. ALHIV were aged 12-16 and recruited from 39 clinics in Uganda between January 2013 and December 2015. The intervention comprised a long-term child development account (CDA), micro-enterprise workshops, and educational sessions. Adherence was measured using unannounced pill counts. We used mixed-effects logistic regression analysis to examine the effect of the intervention on ART adherence. The mean age was 12.6 years. Despite observing non-significant group main effects, we found significant group-by-time interaction effects χ²(5) = 45.41, p < 0.001. Pairwise comparisons showed that compared to the control group, participants who received the intervention had significantly higher adherence at visit four, OR = 1.52 (95% CI: 1.07-2.18), p = 0.020; visit five, OR = 1.59 (95% CI: 1.06-2.38), p = 0.026; and visit six, OR = 1.94 (95% CI: 1.24-3.04), p = 0.004. Efforts to support ALHIV to live longer and healthier lives should incorporate components addressing poverty. However, declining adherence raises concerns over ALHIV's long-term well-being. The trial was registered at ClinicalTrials.gov, registration number NCT01790373, with a primary outcome of adherence to HIV treatment.
