【摘要】目的：越来越多的证据表明，男同性恋和双性恋男性在性行为、安全套使用和HIV预防服务利用（例如HIV检测、PrEP[暴露前预防] 使用）方面可能存在差异，但这仍然没有得到充分探索，尤其是在中国的男同性恋和双性恋男性。方法：我们在中国的一个地理社交网络应用程序上对4,142名男同性恋和双性恋男性进行了调查。结果：在调整后的模型中，双性恋男性在其一生中接受HIV检测 (AOR=.62, 95% CI [.53, .72]) 或最近接受过HIV检测 (AOR=.78, 95% CI [.68, .90]）。相反，在过去6个月内发生过肛交的人中，双性恋男性比男同性恋者更有可能持续使用安全套（OR =1.38, 95% CI [1.17, 1.62]）。与男同性恋相比，双性恋男性明显不太可能意识到PrEP（AOR=.62, 95% CI [.52, .74]），并且显着不太愿意使用PrEP（AOR=.58, 95% CI [ .46, .73]）。结论：在中国独特的社会文化影响性行为的背景下，需要量身定制的HIV预防干预措施来解决双性恋男性的需求。

[Abstract] Objectives: Accumulating evidence suggests that there may be differences in sexual behaviors, condom use, and HIV prevention service utilization (e.g., HIV testing, PrEP use)between gay and bisexual men, but this remains under-explored, especially among gay and bisexual men in China. Methods: We surveyed 4,142 gay and bisexual men on a geosocial networking app in China. Results: In adjusted model, bisexual men were less likely to have received HIV testing in their lifetime (AOR=.62, 95% CI [.53, .72]) or to have received a recent HIV test (AOR=.78, 95% CI [.68, .90]). Conversely, among those who reported having had anal sex in the past six months, bisexual men were more likely to report consistent condom use than gay men (OR = 1.38, 95%CI [1.17, 1.62]). Compared with gay men, bisexual men were significantly less likely to be aware of PrEP (AOR=.62, 95% CI [.52, .74]) and significantly less willing to use PrEP (AOR=.58, 95% CI [.46, .73]). Conclusions: Tailored HIV prevention interventions are needed to address bisexual men’s needs in the context of the unique sociocultural influences on sexual behavior in China.
