A major determinant of adult mortality in sub-Saharan Africa is HIV infection, yet knowledge of the way mortality changes by duration of HIV infection in Africa is based on only a few hundred individuals. We present a retrospective cohort study of 1949 South African gold-miners, with known dates of seroconversion to HIV, and follow-up of >10 years, compared to 6222 HIV-negative men. While employed, 259 HIV-positive and 249 HIV-negative miners died, giving all-cause mortality rates of 30/1000 in the HIV-positive and 6/1000 in the HIV-negative. Mortality rates were stable in the HIV-negatives over time, but increased quickly with time since seroconversion in the HIV-positives: 6/1000 at <1 year, 18/1000 at 1-2 years, 54/1000 at 4-5 years - similar rates to those in the West before antiretrovirals . Full results, including home follow-up, will be presented. The proportion of deaths in South Africa attributable to HIV over time will be estimated.
