ABSTRACT
Objective@#To analyze the influence of the confidence to pre-exposure prophylaxis (PrEP) on the willingness to use PrEP in men who have sex with men (MSM) by using the path analysis model based on structural equation model approach.@*Methods@#A total of 550 MSM were recruited in Urumqi by snowball method and a questionnaire survey was conducted among them. According to the professional knowledge and analysis results of the confidence and willingness to use PrEP, structural equation model (SEM) analysis method was used to construct a path analysis model.@*Results@#A total of 513 MSM participated in the survey. The modified path equation model was well fitted, with the modified fitting index as: GFI=0.993, RMSEA<0.001, and AGFI=0.984. The confidence to PrEP had direct influence on the willingness; the degree of influence from sex partners, the attitude of sex partner to PrEP and the positive emotions not only had direct effects on willingness of PrEP use, but also had indirect effects on willingness of PrEP use by affecting the confidence to it; the role in sexual behavior, AIDS severity, HIV prevention behavior had direct effects on willingness of PrEP use. The proportion of HIV infection in the population had no direct effects on willingness of PrEP use, but had indirect effects on willingness of PrEP use by affecting the confidence to it.@*Conclusions@#The confidence to PrEP had influence on willingness of PrEP use in MSM, therefore targeted activities can be conducted to improve the confidence and willingness of MSM in taking the PrEP and reducing the risk of HIV infection in MSM. Compared with the traditional multiple regression analysis, the path analysis using the structural equation model could better reveal the mediating effect between the independent variables and dependent variables.
ABSTRACT
Objective To understand the human papilloma virus (HPV) infection status in men who have sex with men (MSM) recruited from gay bathhouses and HIV voluntary counseling and testing (VCT) clinics in Urumqi,Xinjiang Uygur autonomous region,and identify the associated risk factors.Methods A total of 200 MSM aged ≥≥ 18 years were recruited by using the "snowballing" sampling method from gay bathhouses and VCT clinics in Urumqi during March-May,2016.The MSM recruited completed questionnaires after filling in the informed consent form.The information about their demographic characteristics and sexual behaviors were collected,and anal swabs were collected from them for HPV genotyping.Results The overall HPV infection rate was 54.0％.The HPV infection rate was 66.7％(74/111) in MSM from gay bathhouses and 38.2％(34/89) in MSM from VCT clinics and the high risk type HPV infection rate was 39.6％ (44/111) in MSM from gay bathhouses and 14.6％(13/89) in MSM from VCT clinics,the differences were significant (x2=16.112,P＜0.05;x2=15.190,P＜0.05).Multiple logistic regression analysis indicated that the major risk factors for HPV infection included activity in gay bathhouse (OR=3.732,95％CI:1.950-7.141) and anal sexual behavior (OR=2.555,95％ CI:1.329-4.912).Conclusion The prevalence of HPV in MSM from gay bathhouses was higher than that in MSM from VCT clinics,indicating that close attention should be paid to the behavior intervention in MSM.

ABSTRACT
Objective Knowledge-motivation-psychological model was set up and tested through structural equation model to provide evidence on HIV prevention related strategy in Men who have Sex with Men (MSM).Methods Snowball sampling method was used to recruit a total of 550 MSM volunteers from two MSM Non-Governmental Organizations in Urumqi,Xinjiang province.HIV prevention related information on MSM was collected through a questionnaire survey.A total of 477 volunteers showed with complete information.HIV prevention related Knowledge-motivationpsychological model was built under related experience and literature.Relations between knowledge,motivation and psychological was studied,using a ‘structural equation model’ with data from the fitting questionnaires and modification of the model.Results Structural equation model presented good fitting results.After revising the fitting index:RMSEA was 0.035,NFI was 0.965 and RFI was 0.920.Thereafter the exogenous latent variables would include knowledge,motivation and psychological effects.The endogenous latent variable appeared as prevention related behaviors.The standardized total effects of motivation,knowledge,psychological on prevention behavior were 0.44,0.41 and 0.17 respectively.Correlation coefficient of motivation and psychological effects was 0.16.Correlation coefficient on knowledge and psychological effects was-0.17 (P＜0.05).Correlation coefficient of knowledge and motivation did not show statistical significance.Conclusion Knowledge of HIV and motivation of HIV prevention did not show any accordance in MSM population.It was necessary to increase the awareness and to improve the motivation of HIV prevention in MSM population.
