Internet group had a higher rate of bleeding (36.4%) when having sexual intercourse in the previous year and a lower proportion of 8.7% exchanged sex for money, and 14.9% and 13.3% in both bar and bath pond groups respectively. Bar group had significant lower rates of condom use with 79.6% while having sex with men and 45.3% with women, but higher rates (28.9%) ever participated in group sex in the last year and 4.2% with HIV infection.

探讨在不同场所曾有过寻找性伴经历的男男性行为者（MSM）中艾滋病相关高危行为的情况。
采用目标抽样（“滚雪球”）进行横断面研究，并采用有效的匿名问卷调查来比较艾滋病相关高危行为的差异。对通过互联网、酒吧或浴池寻找性伴的9个城市的1834名MSM进行了研究。
与其他相应组相比，浴池组的MSM总性伴数、与同性进行肛交和口交的次数以及前6个月肛交次数中位数分别显著更多，分别为40次、16次、20次和4次。互联网组在前一年性交时有出血的比例较高（36.4%），以性换钱的比例较低（8.7%），酒吧组和浴池组分别为14.9%和13.3%。酒吧组在与男性发生性行为时使用避孕套的比例显著较低，为79.6%，与女性发生性行为时为45.3%，但去年曾参与群交的比例较高（28.9%），感染HIV的比例为4.2%。
MSM在寻找性伴时在不同场所均出现了与艾滋病相关的高危行为。应根据不同亚人群的特点采取干预策略，尤其是针对浴池组。
