Changes in HIV prevalence and sexual behavior among men who have sex with men in a northern Chinese city: 2002–2006

HIV, Syphilis Infection, and Risky Sexual Behaviors among Male University Students Who Have Sex with Men in Beijing, China: A Cross-Sectional Study

“…Over 90% of our participants reported engaging in anal intercourse, and 66% of these participants reported UAI in the past 6 months. Our findings are consistent with other studies that have shown high proportions of MSM engaging in UAI in the past 6 months (49%-72%) (Choi et al, 2004;Ruan et al, 2008;Zhang et al, 2007a). Intensified Note.…”

Genetic Characterization and Transmitted Drug Resistance of the HIV Type 1 Epidemic in Men Who Have Sex with Men in Beijing, China

“…In previous studies in MSM in China, subtype B was found to be dominant. 19,20 Different from those reports, CRF01_AE strains were found to surpass subtype B strains in Beijing MSM. This finding is also supported in another study that reported that subtype CRF01_AE had displaced subtype B as the dominant subtype in samples collected between 2008 and 2009 in Beijing MSM.…”

“…25 Due to social discrimination and cultural stigma associated with homosexual behavior in China, 31.5% of HIV-positive MSM are estimated to engage in sex with both men and women within and out of marriage. 20 This behavior facilitates the transmission of HIV from high-risk populations to the general population, and may contribute to the growing number of HIV-positive women infected through unprotected sex. The distinct characteristics of HIV cases within the MSM population in China mean that it is important to understand how this can impact the spread of the virus.…”

Willingness of Chinese injection drug users to participate in HIV vaccine trials

“…First, though HIV prevalence rates vary among some Chinese high risk populations such as sex workers [5][6][7], men who have sex with men [8][9][10] and former plasma donors [11][12], incidence is low or lacking [13], only IDUs cohorts in southwestern and northwestern Chinese provinces such as Sichuan, Guangxi and Xinjiang have shown high HIV incidence rates from 3.1 to 8.8% and moderate 12-month retention rates from 70 to 93% [14][15][16]. Typically, a cohort with <2% HIV seroincidence and <90% 1-year retention is considered inappropriate for phase III vaccine trials, because in this situation the sample size required would be too large for an effect to be shown.…”
