Influencing factors of molecular network transmission clusters of HIV/AIDS in Huzhou / 预防医学

ABSTRACT

Objective @#To analyze the influencing factors for the molecular network transmission clusters of HIV/AIDS, and to provide scientific evidence for the precise prevention and control of AIDS. @*Methods@#A case-control study was conducted. The HIV/AIDS cases reported from January 2017 to June 2019 in Huzhou with strong clustering of HIV molecular transmission were recruited as the case group, and the residents with same gender, similar age ( ±three years ) and HIV negative in the same community and period were matched ( 1∶4 ) as the control group. Demographic characteristics, AIDS related knowledge and sexual behaviors were collected by a questionnaire survey. The Cox regression model was used to analyze the influencing factors for HIV/AIDS molecular network transmission cluster.@*Results @#There was 100 people in the case group and 400 people in the control group, the differences between them in age, sex, marital status, place of residence and educational level were not statistically significant ( P>0.05 ) . The results of multivariate Cox regression analysis showed that awareness of AIDS related knowledge ( HR=0.145, 95%CI 0.059-0.352 ) was a protective factor for molecular network transmission clusters of HIV/AIDS; men who have sex wth men ( MSM, HR=9.614, 95%CI 4.645-19.901) , seeking homosexual partners through the internet (HR=16.321, 95%CI 7.016-32.968) and having syphilis ( HR=3.314, 95%CI 1.073-10.232 ) were risk factors for molecular network transmission clusters of HIV/AIDS.@*Conclusions@#The awareness of AIDS related knowledge, MSM, seeking homosexual partners through the internet and suffering from syphilis are the influencing factors for molecular network transmission clusters of HIV/AIDS.
