We examined the characteristics of young Internet-using men who have sex with men (MSM) and risks associated with seeking sex online, offline, or through both strategies.
Data were obtained from MSM aged 18 to 24 years who completed a 45-minute online survey regarding sex and Internet use in the preceding 3 months.
Significantly more Internet-using MSM who had met sexual partners both online and offline (43%) reported unprotected anal intercourse than did those who had met sexual partners exclusively online (29%) or offline (34%). MSM who met sexual partners exclusively offline reported the fewest partners but the greatest proportion of partnerships involving unprotected anal intercourse (49%). Meeting sexual partners both online and offline (odds ratio [OR]=3.38-58.42) and being drunk (OR=1.57) or high (OR=2.24) increased the odds of having more sexual partners. The same factors increased the odds of having unprotected anal intercourse (online and offline sexual partners, OR=1.60; being drunk, OR=1.43; being high, OR=1.61).
Risky sexual behavior was prevalent among all of the study subgroups. Our findings suggest that online sex seeking is associated with greater numbers of sexual partners but neither promotes nor discourages unprotected anal intercourse. Regardless of where sexual partners met, being drunk and high were significant risks for unprotected anal intercourse.
我们研究了与男性发生性行为的年轻上网男性(男男性行为者)的特征,以及通过线上、线下或两种方式寻找性伴侣所带来的风险。
数据来自年龄在18至24岁的男男性行为者,他们完成了一项关于前三个月性行为和互联网使用情况的45分钟在线调查。
与仅通过线上(29%)或线下(34%)结识性伴侣的男男性行为者相比,通过线上和线下两种方式结识性伴侣的上网男男性行为者(43%)报告的无保护肛交比例显著更高。仅通过线下结识性伴侣的男男性行为者报告的性伴侣最少,但涉及无保护肛交的性伴侣比例最高(49%)。通过线上和线下两种方式结识性伴侣(优势比[OR]=3.38 - 58.42)、醉酒(OR=1.57)或吸毒(OR=2.24)会增加拥有更多性伴侣的几率。相同因素也会增加无保护肛交的几率(线上和线下性伴侣,OR=1.60;醉酒,OR=1.43;吸毒,OR=1.61)。
危险的性行为在所有研究亚组中都很普遍。我们的研究结果表明,通过网络寻找性伴侣与更多的性伴侣数量相关,但既不促进也不抑制无保护肛交。无论性伴侣是在哪里结识的,醉酒和吸毒都是无保护肛交的重大风险因素。
