TLDR
HIV and syphilis prevalences among MSM in China are high and the 2 epidemics are largely separate geographically, but three segments of the Chinese MSM population each have different demographic and sexual risk "profiles" that suggest high potential for bridging infection across geographies, generations, and sexes.Abstract:
Background. Human immunodeficiency virus (HIV) has rapidly spread among men who have sex with men (MSM) in China in recent years; the magnitude of the epidemic is unclear. We sought to test 3 hypotheses: (1) The prevalence of both HIV and syphilis among MSM in China is high, (2) the 2 epidemics each have unique geographical distributions, and (3) demographic and sexual behavior characteristics are different among segments of the MSM population in China.
Methods. A total of 47 231 MSM from 61 cities in China participated in a cross-sectional survey conducted from February 2008 to September 2009. Demographic and behavioral data were collected and analyzed and blood samples tested for HIV and syphilis. Three subgroups among the broader MSM sample were described. Main outcome measures were HIV and syphilis prevalence.
Results. An overall prevalence of 4.9% (2314/47 231; 95% confidence interval [CI], 4.7%–5.1%) for HIV and 11.8% (5552/47 231; 95% CI, 11.5%–12.0%) for syphilis was found. Syphilis-positive MSM had the highest HIV prevalence, 12.5% (693/5552; 95% CI, 11.6%–13.4%). However, correlations between HIV and syphilis prevalence were found in only 3 of 6 geographical regions (Northwest: r = 0.82, P = .0253; East: r = 0.78, P = .0004; and South-central: r = 0.63, P = .0276). Three subgroups—nonlocal MSM, Internet-using MSM, and female-partnering MSM—were found to have different profiles of characteristics and behaviors.
Conclusions. HIV and syphilis prevalences among MSM in China are high and the 2 epidemics are largely separate geographically. Three segments of the Chinese MSM population each have different demographic and sexual risk “profiles” that suggest high potential for bridging infection across geographies, generations, and sexes.read more

TL;DR: Internet-user MSM were more likely to have been: younger, currently single, better educated, health-insured, with higher income, with Beijing residency (‘Hukou’), living longer in the city, HIV-positive, ever using drug and engaging in condomless receptive anal sex.

TL;DR: Socio-cultural barriers for HIV control and prevention found in this study call for serious and imperative consideration on integrated measures, including targeted efforts towards effective sex education and further inclusion of socio-cultural perspectives in HIV/AIDS interventions for gay men.

TL;DR: It is reinforced that each recruitment method may reach a sub-group of MSM with a specific risk profile, so multiple methods may be needed to obtain a representative sample of MSM.

Drug use and sexual behaviors among MSM in China.
TL;DR: Analysis of patterns of drug use and related correlates among a sample of men who have sex with men (MSM) and men who sell sex to other men (aka “money boys”) in China suggests that drugUse and sexual behaviors after drug use among Chinese MSM differ widely based upon selling sex and separate intervention strategies may be appropriate.
