[Analysis of survival and influencing factors of HIV/AIDS patients in Tianjin, 2004-2014].

Objective To understand the survival and influencing factors of HIV/AIDS patients in Tianjin. Methods The data of HIV/AIDS cases reported in Tianjin during 2004-2014, which were collected from National AIDS Prevention and Control Information System, were analyzed by using life table and Kaplan Meier method to calculate survival time and the survival rate, and univariate and multivariate Cox regression analysis was conducted to identify the influencing factors for survival time. Results For the 2 775 HIV/AIDS patients, 1 year, 3 years, 5 years, 10 years and 11 years cumulative survival rates were 91%, 88%, 86%, 79% and 79% respectively. The risk of death in AIDS patients was higher than that in people living with HIV (χ2=107.622, P<0.001); Factors affecting the survival of people living with HIV were the first time CD4 value and antiviral treatment, and the influencing factors for survival of AIDS patients were the infection route, detection ways, first time CD4 value and antiviral treatment. Conclusion Early detection and early treatment can obviously reduce the risk for death of people living with HIV/AIDS. To improve the survival of HIV/AIDS patients, it is necessary to strengthen the early detection and early treatment of HIV infection. Key words: HIV/AIDS; Survival time; Influencing factor
