男男性行为者（MSM）在中国艾滋病流行中所占的比例可能越来越大，但由于高度的耻辱感，仍然很难进行流行病学研究。我们比较了在中国广州获得的两个MSM样本的组成。第一次调查于2004年进行，通过方便抽样招募MSM。2006年的第二次调查在受访者驱动的抽样背景下使用了长链推荐招聘。与方便抽样相比，长链转诊方法包括更高比例的被认为处于艾滋病毒感染高风险和更难以接触的男男性行为者亚群，包括国内移民和从事商业性行为的人。长链转诊也招募了更多25岁以下、失业、受教育程度较低的MSM。我们认为，长链转诊招募将比便利抽样更有效地跟踪中国MSM流行的前沿。
Men who have sex with men (MSM) may account for an increasing proportion of China's HIV epidemic, but remain difficult to access for epidemiological studies due to high stigma. We compare the composition of two samples of MSM obtained in Guangzhou, China. The first survey, conducted in 2004, recruited MSM through convenience sampling. The second survey in 2006 used long-chain referral recruitment in the context of respondent-driven sampling. Compared to convenience sampling, the long-chain referral method included higher proportions of subgroups of MSM thought to be at elevated risk for HIV infection and more difficult to reach, including internal migrants and those engaging in commercial sex. Long-chain referral also recruited more MSM who were under 25 years, unemployed, and had lower education. We conclude that long-chain referral recruitment will be more effective in tracking the leading edge of the epidemic among MSM in China than convenience sampling.
