Respectively, 387 and 316 men who have ever had anal or oral sex with men (MSM) in Kunming, China, were interviewed in 2005 and 2006. In both surveys, over 85% reported having had anal sex with noncommercial male sex partners; around 60% had ever had female sex partners; and about 16% engaged in commercial anal sex in the last 6 months. The prevalence of unprotected anal sex decreased over time (last episode of anal sex with noncommercial MSM partner: 37.7% (2005) versus 21.9% (2006) (Adjusted odds ratio [OR] = 0.43); last episode of anal sex with commercial MSM partner, 20.8% (2005) versus 10.8% (2006) (Adjusted OR = 0.50). Some behavioral changes may have occurred. Multivariate analyses showed that study year (OR = 2.24), age (OR = 1.64), marital status (OR = 2.07), and perceived infectivity related to unprotected sex with people living with HIV/AIDS (OR = 0.3) were associated with condom use in the last episode of anal sex with noncommercial MSM partners.
2005年和2006年，分别对中国昆明387名和316名曾与男性发生肛交或口交的男性进行了访谈。在这两项调查中，超过85%的人报告与非商业性男性性伴侣发生过肛交；约60%的人曾有过女性性伴侣；约16%的人在过去6个月内从事过商业性肛交。无保护肛交的比例随时间下降（与非商业性男性性伴侣的最后一次肛交：2005年为37.7%，2006年为21.9%（调整优势比[OR]=0.43）；与商业性男性性伴侣的最后一次肛交，2005年为20.8%，2006年为10.8%（调整OR=0.50）。可能发生了一些行为变化。多变量分析显示，研究年份（OR=2.24）、年龄（OR=1.64）、婚姻状况（OR=2.07）以及与与艾滋病毒/艾滋病感染者进行无保护性行为相关的感染感知（OR=0.3）与与非商业性男性性伴侣的最后一次肛交中使用避孕套有关。
