Analysis On Influencing Factors Of AIDS Risk Assessment Among Male Homosexuality With Structural Equation Model

Objective To investigate the situation of AIDS perception and risk sex behaviors among men who have sex with men(MSM)in Tianjin;Use structural equation model to:Explain the relation between AIDS perception,sex behaviors and AIDS risk assessment;Explore the relation between AIDS risk assessment,voluntary HIV test and finding sex partner through Internet and their interactive effects for preventing AIDS among MSM.Method Investigator spread recruit information at a gay website in Tianjin.The responders completed questionnaires at our survey website and got a test number and can get a free test of HIV and syphilis.Data analyze:At first,we made descriptive statistics of AIDS risk assessment and risk sex behaviors.Then we built the measurement model with factor analysis and explained the influencing factors of AIDS risk assessment with structural equation model.Result Our responders were relative young.Percent of MSM aged from 18 to 35 was 86.4%.72.6%of them were graduate education and self identified gay was 66.7%. Most of them had multi-sex partners with low condom using.Under structural equation modeling,the risk factors of AIDS risk assessment were:sex partner number, social status,high risk sex behaviors,and low risk sex behaviors.Their effect indexes of these factors were:0.271,0.126,0.119,and 0.063 respectively.The protective factors were knowledge of AIDS transmitted way with the effect index -0.104 and -0.025.Meanwhile these factors affected voluntary HIV test.The strongest factor of them was social status with the effect index 0.328.Finding sex partner through Internet was affected by number of sex partners and high risk sex behavior.There was no relation between finding sex partner through Internet and AIDS risk assessment, voluntary HIV test.98 persons got free test.The positive rate of HIV and syphilis were 2.0%(2/98)and 11.8%(11/98)respectively.Conclusion Most of MSM in Tianjin were young with high level of education and knowledge of AIDS transmitted way but the risk sex behaviors were common.Our research show that AIDS risk assessment was affected by AIDS knowledge perception directly and AIDS knowledge perception affected AIDS risk assessment through number of sex partners and sex behaviors at the same time.It meant that the knowledge level of AIDS prevention among MSM affected their sex behavior and assessment of infecting AIDS risk.Then AIDS risk assessment affected voluntary HIV test.Finding sex partners online was affected by the number of sex partners and high risk sex behavior.In the future intervention we should spread knowledge of AIDS and improve the ability of risk assessment of MSM to make them evaluate the risk level of their behaviors precisely and take protective method behavior such as HIV test.
