Men who have sex with men (MSM) are a hidden but emerging population susceptible to HIV infection against a background of rapidly increasing HIV prevalence in China. Low HIV testing levels and multiple partnerships among MSM are two major contributing factors to HIV transmission.
We conducted a cross-sectional survey among 447 Chinese MSM in Changsha and Tianjin cities from November to December 2011 using an anonymous questionnaire. We aim to investigate (1) the trend of HIV testing rates among Chinese MSM during 2009 to 2011; and (2) the patterns of multiple sexual relationships with male, female and commercial partners.
The self-reported past-12-months HIV testing level among Chinese MSM increased from 16.6% in 2009 to 46.3% in 2010 and 58.6% in 2011 (χ(2) = 173.49, p < 0.001). Compared with men who have tested for HIV, the never-tested MSM were generally younger, never married, students, and more likely to have unprotected anal intercourse with non-commercial male partners. Furthermore, 21.3% (56/263) MSM reported having multiple regular male and female sexual partnerships and 6.2% (16/257) reported having commercial male partners in the past six months. However, individuals who were never-tested for HIV are consistently less likely to engage in multiple sexual relationships.
HIV testing rates have increased substantially among Chinese MSM in the period 2009-2011, although significant barriers to testing remain. Multiple sexual partnerships, and especially bisexual behaviours, are common among Chinese MSM.
在中国，男男性行为者（MSM）是一个隐匿但正在兴起的人群，在艾滋病病毒（HIV）患病率迅速上升的背景下，他们易感染HIV。MSM中HIV检测水平低以及存在多个性伴侣是导致HIV传播的两个主要因素。
2011年11月至12月，我们采用匿名问卷调查的方式，对长沙和天津两市的447名中国MSM进行了横断面调查。我们旨在调查：（1）2009年至2011年期间中国MSM中HIV检测率的变化趋势；（2）与男性、女性及商业性伙伴发生多段性关系的模式。
中国MSM中自我报告的过去12个月HIV检测水平从2009年的16.6%升至2010年的46.3%，并在2011年达到58.6%（χ(2) = 173.49，p < 0.001）。与进行过HIV检测的男性相比，从未检测过的MSM通常更年轻、未婚、是学生，并且更有可能与非商业性男性伙伴发生无保护肛交。此外，21.3%（56/263）的MSM报告在过去六个月中有多个固定的男性和女性性伴侣，6.
