BACKGROUND: Women have better patient outcomes in HIV care and treatment than men
in sub-Saharan Africa. We assessed--at the population level--whether and to what
extent mass HIV treatment is associated with changes in sex disparities in adult
life expectancy, a summary metric of survival capturing mortality across the full
cascade of HIV care. We also determined sex-specific trends in HIV mortality and
the distribution of HIV-related deaths in men and women prior to and at each
stage of the clinical cascade. METHODS AND FINDINGS: Data were collected on all
deaths occurring from 2001 to 2011 in a large population-based surveillance
cohort (52,964 women and 45,688 men, ages 15 y and older) in rural KwaZulu-Natal,
South Africa. Cause of death was ascertained by verbal autopsy (93% response
rate). Demographic data were linked at the individual level to clinical records
from the public sector HIV treatment and care program that serves the region.
Annual rates of HIV-related mortality were assessed for men and women separately,
and female-to-male rate ratios were estimated in exponential hazard models.
Sex-specific trends in adult life expectancy and HIV-cause-deleted adult life
expectancy were calculated. The proportions of HIV deaths that accrued to men and
women at different stages in the HIV cascade of care were estimated annually.
Following the beginning of HIV treatment scale-up in 2004, HIV mortality declined
among both men and women. Female adult life expectancy increased from 51.3 y (95%
CI 49.7, 52.8) in 2003 to 64.5 y (95% CI 62.7, 66.4) in 2011, a gain of 13.2 y.
Male adult life expectancy increased from 46.9 y (95% CI 45.6, 48.2) in 2003 to
55.9 y (95% CI 54.3, 57.5) in 2011, a gain of 9.0 y. The gap between female and
male adult life expectancy doubled, from 4.4 y in 2003 to 8.6 y in 2011, a
difference of 4.3 y (95% CI 0.9, 7.6). For women, HIV mortality declined from
1.60 deaths per 100 person-years (95% CI 1.46, 1.75) in 2003 to 0.56 per 100
person-years (95% CI 0.48, 0.65) in 2011. For men, HIV-related mortality declined
from 1.71 per 100 person-years (95% CI 1.55, 1.88) to 0.76 per 100 person-years
(95% CI 0.67, 0.87) in the same period. The female-to-male rate ratio for HIV
mortality declined from 0.93 (95% CI 0.82-1.07) in 2003 to 0.73 (95% CI
0.60-0.89) in 2011, a statistically significant decline (p = 0.046). In 2011, 57%
and 41% of HIV-related deaths occurred among men and women, respectively, who had
never sought care for HIV in spite of the widespread availability of free HIV
treatment. The results presented here come from a poor rural setting in southern
Africa with high HIV prevalence and high HIV treatment coverage; broader
generalizability is unknown. Additionally, factors other than HIV treatment
scale-up may have influenced population mortality trends. CONCLUSIONS: Mass HIV
treatment has been accompanied by faster declines in HIV mortality among women
than men and a growing female-male disparity in adult life expectancy at the
population level. In 2011, over half of male HIV deaths occurred in men who had
never sought clinical HIV care. Interventions to increase HIV testing and linkage
to care among men are urgently needed.
