评估互联网男男性行为者（MSMUI）的艾滋病毒和梅毒感染及其危险行为。2007年，通过互联网在中国北京和乌鲁木齐招募了429名MSMUI。进行了问卷调查，并收集了血液标本，进行了艾滋病毒和梅毒检测。参与者的中位年龄为25岁。终生性伴侣的中位数为10。90.7%的人曾与网友发生过性关系。最近一次口交、插入和接受肛交时安全套使用率分别为9.1%、66.3%和60.4%。HIV感染率为4.8%，梅毒感染率为11.4%，HIV/梅毒混合感染率为1.7%。HIV感染的相关因素为≤24岁（OR=2.85，95%CI：1.05-7.75），梅毒阳性（OR=4.78，95%CI：1.68-13.58），使用非水基液体作为润滑剂（OR=8.03，95% CI：1.03-62.52）和无安全套口交时牙龈出血或口腔溃疡（OR=3.17，95% CI：1.13-8.88）。MSMUI从事高危性行为，艾滋病毒和梅毒感染率高。互联网是大多数MSMUI寻找性伴侣的主要场所。针对这一群体实施有效的干预方案是当务之急。
To assess HIV and syphilis infections among men who have sex with men who use the Internet (MSMUI) and their risk behaviors. In 2007, 429 MSMUI were recruited via the Internet in Beijing and Urumqi, China. A questionnaire was administered, and a blood specimen collected and tested for HIV and syphilis. Median age of participants was 25 years. Median number of lifetime sexual partners was 10. Ninety point seven percent ever had sex with a cyber-friend. Rates of condom use in the last oral, insertive and receptive anal sex were 9.1%, 66.3% and 60.4% respectively. Infection rates of HIV, syphilis and HIV/syphilis co-infection were 4.8%, 11.4%, and 1.7% respectively. Factors associated with HIV infection were being ≤24 years (OR=2.85, 95% CI: 1.05–7.75), syphilis positive (OR=4.78, 95% CI: 1.68–13.58), used non-water-based liquid as lubricant (OR=8.03, 95% CI: 1.03–62.52) and having bleeding gums or oral ulcers during condom-free oral sex (OR=3.17, 95% CI: 1.13–8.88). MSMUI engage in high-risk sexual behaviors and have a high prevalence of HIV and syphilis infections. The internet is the predominant venue for the majority of MSMUI to find sexual partners. It is urgent to implement effective intervention programs targeting this group.
