China has a significant population of MSM (men who have sex with men) and they have been becoming very much alive in many ways since 1990s due to recent social changes. Some surveys indicate that great many of MSM are engaged in high-risk behaviors. In addition, majority of MSM have also experienced sexual encounters with women sometimes in their lives, which possibly con- tribute to spread of HIV to women. Some reports documented that HIV is becoming rampant among MSM since more than 1% of them are now infected. Political, cultural and custom elements could hinder intervention activities against HIV spread among MSM. Fortunately, many cities in China have seen that MSM were in cooperation with responsible institutions carrying out certain intervention measures. The general situation is promising. The authors forecast that the fast HIV spread among MSM of China could possibly be halted within several years when the authorities become more sensible to this issue, health service institutions offer unswerving efforts toward the MSM community and those who involve in MSM undertakes necessary responsibilities.展开更多

Women who have sex with women have also been known to avoid routine physical examinations and conceal their same-sex history from physicians, which can affect their ability to receive an accurate diagnosis and treatment. No previous research has targeted women who have sex with women in China. We sought to describe women who have sex with women in China and explore risk factors for their reproductive tract infections (RTI)/sexually transmitted infections (STI). Methods Participants were recruited through outreach in venues and online for a cross-sectional study. Data were collected using interviews and laboratory tests. Results We recruited 224 women who have sex with women. In the year preceding their participation in the study, 92% (206/224) of women reported sexual relations with women. The RTI rates were: gonorrhea (15.8%), chlamydia (3.5%), syphilis (0.5%), bacterial vaginosis (14.4%), hepatitis B virus (HBV) (0.9%), hepatitis C virus (HCV) (0.5%), and candidiasis (6.9%). No HIV or herpes simplex virus (HSV) positive cases were detected. Factors associated with gonorrhea infection were non-Beijing local residency (odds ratio (OR)=2.1, 95% confidence interval (C/): 1.2-3.8) and genital-genital contact (OR=3.1, 95% CI: 1.3-7.2); factors associated with curable STI (excluding bacterial vaginosis, candidiasis, HBV and HCV) were non-Beijing local residency (OR=1.9; 95% CI: 1.2-3.0) and bleeding during or after sex (OR=18.1; 95% CI: 5.2-62.6); and the factor associated with RTI (including all the infections tested) was bleeding during or after sex (OR=37.8, 95% CI: 11.2-127.4).
