The Health Impact of a Decade of Free ART Access in South Africa

Background: Since 2004 the South African government has rolled out free antiretroviral therapy (ART) at public health care facilities nationwide. No prior studies have estimated the impact of the ART rollout on health and survival based on a longitudinal household survey with national coverage.
Methods: We match household member deaths and self-assessed health from a large national longitudinal survey to community-level ART enrollment indicators to estimate the reduction in mortality and morbidity attributable to ART access. We focus our analysis on black Africans aged 25-49 because this demographic group represents more than two-thirds of all South African HIV cases.
Findings: We find that access to ART has reduced annual mortality by 0∙5 percentage points (95% CI - 0∙80 – -0∙11) and has decreased the likelihood of reporting poor health by 1∙8 percentage points (95% CI -3∙00 – -0∙66) for black Africans aged 25-49. In relative terms, these estimates amount to annual reductions of 30∙7% in annual mortality and a reduction of 46.6% in the proportion of individuals reporting poor health in this demographic category.
Interpretation: Our findings confirm that access to ART treatment had a dramatic impact on health, both in terms of prolonged survival, and in terms of improved health-related quality of life, with most of these gains concentrated among the high HIV prevalence group of black Africans aged 25-49.
