Abstract:
Objective To analyze the positive conversion rate of negative spouse and the survival analysis on HIV sero－discordant couples． Methods Data were collected from the case report database of the integrated AIDS prevention and control data and information system． HIV sero－discordant couples diagnosed between September 1，1997 and September 1，2018 were recruited into the cohort． The participants were divided into three groups as untreated subgroup，routine treatment subgroup and early treatment subgroup according to the situation when they started HIV treatment． The positive conversion rate of negative spouse and the survival were compared among the three subgroups． Ｒesults 598 HIV sero－discordant couples were recruited and the overall survival time of the three subgroups were 258. 92，4 987．17 and 862．25 person－year． The rate of positive conversion were 6. 18/100，0. 48/100 and 0. 23/100 person－year． Multivariate Cox regression model showed that the hazard ratio of routine treatment subgroup ( HＲ = 0. 052，95% CI: 0. 037－0. 074) and early treatment subgroup ( HＲ=0. 011，95% CI: 0. 003－0. 035) were lower than untreated subgroup． The risk of death of women was lower than that of men( HＲ=0. 667，95% CI: 0. 472－0. 944) ; the older the age，the higher the risk of death ( HＲ=1. 041，95% CI: 1. 026－1. 056) ; and the risk of death of the unemployed is higher than that of farmers ( HＲ=1. 571，95% CI: 1. 037－2. 381) ． Conclusion Targeted interventions methods and early antiviral therapy should be taken urgently for sero－discordant couples．
