Achieving equity in HIV treatment outcomes: can social protection improve adolescent ART adherence in South Africa?
ABSTRACT Low ART adherence amongst adolescents is associated with morbidity, mortality and onward HIV transmission. Reviews find no effective adolescent adherence promoting interventions. Social protection has demonstrated benefits for adolescents, and could potentially improve ART adherence. This study examines associations of 10 social protection provisions with adherence in a large community based sample of HIV positive adolescents. All 10 19 year olds ever ART initiated in 53 government healthcare facilities in a health district of South Africa's Eastern Cape were traced and interviewed in 2014 2015 (n 1175 eligible) About 90% of the eligible sample was included (n 1059) Social protection provisions were "cash/cash in kind" government cash transfers, food security, school fees/materials, school feeding, clothing; and "care" HIV support group, sports groups, choir/art groups, positive parenting and parental supervision/monitoring. Analyses used multivariate regression, interaction and marginal effects models in SPSS and STATA, controlling for socio demographic, HIV and healthcare related covariates. Findings showed 36% self reported past week ART non adherence <95% Non adherence was associated with increased opportunistic infections (p .005, B .269, SD .09) and increased likelihood of detectable viral load at last test >75 copies/ml) (aOR 1.98, CI 1.1 3.45) Independent of covariates, three social protection provisions were associated with reduced non adherence: food provision (aOR .57, CI .42 .76, p .001) HIV support group attendance (aOR .60, CI .40 .91, p .02) and high parental/caregiver supervision (aOR .56, CI .43 .73, p .001) Combination social protection showed additive benefits. With no social protection, non adherence was 54% with any one protection 39 41% with any two social protections, 27 28% and with all three social protections, 18% These results demonstrate that social protection provisions, particularly combinations of "cash plus care" may improve adolescent adherence. Through this they have potential to improve survival and wellbeing, to prevent HIV transmission, and to advance treatment equity for HIV positive adolescents.
