[Investigation of mortality among HIV-infected intravenous drug users in Ruili region of Yunnan province].
The investigation of death condition of HIV infected intravenous drug users (IVDU) was conducted with a retrospective cohort study in Ruili city of Yunnan province from 1989-Oct to 1993-Oct, the deaths among 395 HIV+ IVDUs add up to 61 and the mortality is 15.4%, which has significant difference compared to the death level of control cohort composed by 192 HIV- IVDUs (add up to 18). The relative risk of death is 1.6 (95% confidence interval 1.0-2.5). After classified by the cause of death, it was found that both maintain high accidence mortality caused mainly by narcotism, violence and suicide. But in death group caused by diseases, the mortality of HIV+ IVDU (8.4%) is much higher than HIV- IVDU (3.1%) (95% confidence interval 1.2-6.1). We also compared non-AIDS mortality between HIV+ and HIV- IVDU according to data of HIV/AIDS surveillance which showed 2 patients died of AIDS in HIV+ IVDU. The difference is also significant (13.8% in HIV+, but 7.9% in HIV- IVDU) and the relative risk is 1.7 (95% confidence interval 1.0-2.8). The results indicated that the lever of reported AIDS cases were probably lower than that of actual AIDS cases existing.
