title: [Study on the mortality and risk factors among HIV-infected individuals during 1989 - 2011 in Dehong prefecture, Yunnan province].
abstract: OBJECTIVE
  To examine the mortality and risk factors among HIV-infected patients during 1989 - 2011 in Dehong prefecture, Yunnan province.
  
  
  METHODS
  All HIV-infected patients reported during 1989 - 2011 in Dehong prefecture who held local residency were included in the study. Mortality rates and cumulative survival rates were calculated. Multiple regression analysis under Cox proportional hazard model was conducted to examine the risk factors for deaths.
  
  
  RESULTS
  A total of 13 006 HIV-infected patients were included in this study including 73.2% males, 79.1% peasants and 48.7% married at the time of reporting. 64.5% of the patients were ethnic minorities, and 68.7% were illiterate or having received only primary school education. All the patients were followed-up for a total of 55 962.30 person-years with 4648 patients died, with overall mortality rate as 8.31/100 person-years. The mortality rate had been increasing from 1990 to 2004 but decreasing since 2005. The average survival time since the identification of HIV infection was 9.48 years overall, and was 16.65 years for those having received antiretroviral treatment (ART) and 7.67 years for those without ART. Data from multiple regression analysis indicated that ART and socio-demographic characteristics such as age, gender, ethnicity, occupation, marital status, education background etc. were significantly associated with death among HIV-infected patients.
  
  
  CONCLUSIONS
  The comprehensive AIDS campaigns including ART had significantly reduced the deaths among HIV-infected patients in Dehong prefecture. More efforts on the scaling up program of ART as well as the enhanced management and follow-up program tailored for HIV-infected patients with different socio-demographic characteristics were needed to further reduce the deaths in the area.
