ABSTRACT
Objective:To explore the demographic characteristics and sexual behavior of men who have sex with men （MSM） in Tianjin， and to compare these aspects between recreational drug users and non-users. Methods:This research was conducted by Tianjin Centers for Disease Control and Prevention. From July to September 2015， various methods such as simple random sampling and snowball sampling were used to recruit MSM. Information was collected through on-site questionnaire surveys， and laboratory tests were conducted to detect human immunodeficiency virus （HIV） infection status in the research subjects. Statistical description and frequency distribution tests on demographic information and behavioral variables were performed. Results:A total of 410 qualified participants， ranged from 17 to 70 years old， were included. A total of 297 （72.4%） MSM were unmarried， 194 （47.3%） had monthly income over 3 000 yuan， 182 （44.4%） MSM had high school education， and 366 （89.3%） were working full-time. Among all 410 participants， 208 MSM self-reported using recreational drugs. Among them， 140 MSM had used Rush Popper. Influencing factors of unprotected anal intercourse （UAI） among Rush Popper users include： more than 30 years old， average monthly income less than 5 000 yuan， and sex with temporary partners （all P<0.05）. Conclusion:Among MSM in Tianjin， the use of recreational drugs is quite common， and Rush Popper is the most commonly used recreational drug. Therefore， it is necessary to establish and strengthen the relevant laws and regulations for the reduction of Rush Popper circulation among the MSM population.
ABSTRACT
Objective To evaluate the association between sexual sensation seeking (SSS) and sexual risk behaviors among men who have sex with men (MSM) in Guangzhou. Methods MSM aged 18 and over were recruited in Zhitong Charity from June 2017 to April 2018. Data on socio-demographic characteristics, sexual behaviors and SSS were collected using an electronic questionnaire. Logistic regression analyses were performed to evaluate the association between SSS and sexual risk behaviors. Results A total of 500 MSM were included in the current study. The mean age of the participants was (27.77±5.96) years old. The multiple logistic regression analyses showed that MSM with high SSS scores were more likely to engage in multiple sexual partners (OR=2.05, 95% CI: 1.40-2.30,P<0.001), one-night stand (OR=2.11, 95% CI: 1.44-3.09,P<0.001), and unprotected anal intercourse (OR=1.70, 95% CI: 1.16-2.50,P=0.007) than those with low SSS scores. Conclusions High SSS is associated with an increased risk of sexual risk behavior among MSM in Guangzhou. The behavior intervention strategy should be tailored for MSM with high SSS to improve the effectiveness to reduce sexual risk behaviors.
ABSTRACT
Objective To identify related factors associated with unprotected anal intercourse (UAI) among HIV-positive men who have sex with men (MSM) in the context of knowing their HIV infection status.Methods HIV positive MSM who known that they had been infected with HIV for more than 6 months and accepted follow up services were recruited by convenience sampling method in Chengdu 2015.Semi-structured questionnaire was used to collect their information,such as demographic characteristics,antiviral therapy and sexual behavior characteristics etc.Logistic regression model was used for univariate and multivariate analyses.Results A total of 330 HIV-positive MSM were recruited,201 eligible MSM were interviewed.The prevalence of UAI in recent six months was 18.41％ (37/201).The results of multivariate logistic regression analysis revealed that the number of anal intercourse with male ≥3 in last month (OR=6.22,95％CI:1.88-20.56),low education level (OR=7.29,95％CI:1.36-39.16),married,divorced or widowed status (OR=4.65,95％CI:1.13-19.17),homosexual cohabitation (OR=3.32,95％CI:1.01-10.95) were the risk factors related with UAI among the HIV-positive MSM.Conclusion Frequent homosexual anal intercourse,low education level,married,divorced or widowed status and homosexual cohabitation might be the risk factors related with UAI in HIV-positive MSM in Chengdu.

ABSTRACT
The disproportionately high prevalence of HIV among men who have sex with men (MSM) is associated with the prevalence of unprotected anal intercourse (UAI), which has been the predominant high-risk behavior of HIV acquisition and transmission. MSM have become a target population for HIV prevention. The aspects affecting the high-risk sexual behaviors of MSM mainly include personal factors, environmental factors, and social psychological factors. Currently widely applied models of acquired immunodeficiency syndrome (AIDS) behavioral intervention include KABP (knowledge, attitude, belief, and practice) model, health belief model, theory of reasoned action, social network theory, and so on. These theories provide a reference for studying various influential factors and elaborating the occurrence of high-risk sexual behaviors of MSM. Exploring and building the comprehensive model and integrating the influencing factors of high-risk sexual behaviors of MSM can help us to predict their ultimate actions in the future. Similarly, it will also provide ideas for the further preventions and interventions in MSM.
ABSTRACT
The prevalence of HIV infections continues to rise among Chinese MSM. This population is prone to has high-risk behaviors including having multiple sexual partners, unprotected anal intercourse (UAI), etc. This paper summarizes the situation of UAI and related influencing factors, including age, educational level, number of sexual partners, recreational drug abusing and related status of discrimination, etc. The purpose of this article is to provide reference for targeted intervention and prevention of HIV among MSM population.

ABSTRACT
Objective To understand the prevalence of and factors associated with unprotected anal intercourse(UAI)among men who have sex with men(MSM)in Beijing.Methods Five hundred MSM were recruited for a survey using Respondent Driven Sampling (RDS)method, from September to October in 2009. A computer-assisted, interviewer-administered questionnaire was used to gather information including demographics, sexual behaviors and condom use social norms(a scaled number). Variables were evaluated by using RDSAT and SAS software.Results Mean age of the participants was 30.6 years, with 96.0% of them as Han ethnicity and68.5% having had at least high school or higher education level. 72.8% of them were unmarried, with 61.7% of them identified themselves as homosexual, 61.2% had ＞ 1 male partners in the past six months, and the prevalence of UAI was 42.0%. Significant bivariate predictors of UAI would include condom use social norms score, role for anal sex with male sex partner, number of male sexual partners in the past 6 months and amount of alcohol consumed. In multivariable analysis, UAI was associated with a higher condom use social norms score(AOR= 1.2, 95%CI: 1.1-1.3), receptive anal intercourse(AOR=2.0, 95%CI: 1.3-3.2)and drinking alcohol more than 3 times per month in the past 12 months(AOR=1.6, 95%CI: 1.1-2.5). Conclusion The prevalence of UAI was high in the MSM community in Beijing, suggesting that efforts should be targeting on how to make the condom use a social norm and being promoted.
