Abstract
Background South Africa (SA) has the greatest HIV prevalence in the world, with rates as high as 40% among pregnant women. Depression is a robust predictor of nonadherence to antiretroviral therapy (ART) and engagement in HIV care; perinatal depression may affect upwards of 47% of women in SA. Evidence-based, scalable approaches for depression treatment and ART adherence in this setting are lacking.
Method Twenty-three pregnant women with HIV (WWH), ages 18-45 and receiving ART, were randomized to a psychosocial depression and adherence intervention or treatment as usual (TAU) to evaluate intervention feasibility, acceptability, and preliminary effect on depressive symptoms and ART adherence. Assessments were conducted pre-, immediately post-, and 3 months post-treatment, and included a qualitative exit interview.
Results Most (67.6%) eligible individuals enrolled; 71% completed at least 75% of sessions. Compared to TAU, intervention participants had significantly greater improvements in depressive symptoms at post-treatment, beta = - 11.1, t(24) = - 3.1, p < 0.005, 95% CI [- 18.41, - 3.83], and 3 months, beta = - 13.8, t(24) = - 3.3, p < 0.005, 95% CI [- 22.50, - 5.17]. No significant differences in ART adherence, social support, or stigma were found. Qualitatively, perceived improvements in social support, self-esteem, and problem-solving adherence barriers emerged as key benefits of the intervention; additional sessions were desired.
Conclusion A combined depression and ART adherence intervention appears feasible and acceptable, and demonstrated preliminary evidence of efficacy in a high-need population. Additional research is needed to confirm efficacy and identify dissemination strategies to optimize the health of WWH and their children.
