This study aimed to investigate the impact of sexual partners' HIV serostatus awareness on the HIV acquisition among men who have sex with men (MSM) in Guangzhou, China. A nested case-control study was conducted based on a prospective cohort of MSM in Guangzhou. Within the cohort, individuals who underwent HIV seroconversion were identified as the case group, and each case was matched with four controls from the non-seroconverted participants. Information regarding the awareness of sexual partners' HIV serostatus over the preceding 6 months was gathered. Of the 161 participants, 36.0% were aware of the HIV serostatus of all their sexual partners. The practice of engaging in condomless anal sex with partners of unknown HIV serostatus and being aware of the HIV serostatus of only some casual partners were positively correlated with an elevated risk of acquiring HIV. Conversely, being fully aware of the HIV serostatus of all sexual partners, including regular ones, was associated with a diminished risk of HIV incidence. Regular communication with sexual partners regarding HIV testing outcomes, honest disclosure of one's own HIV serostatus, and refusal of sexual contact with partners of unknown HIV serostatus can potentially mitigate the risk of acquiring HIV among MSM.
本研究旨在探讨性伴侣 HIV 感染状况知晓情况对中国广州男男性行为人群（MSM）中 HIV 感染的影响。本研究基于广州 MSM 的前瞻性队列，采用巢式病例对照研究方法。在队列中，HIV 血清转换者被确定为病例组，每个病例与非血清转换参与者中的 4 名对照相匹配。收集了过去 6 个月内性伴侣 HIV 感染状况知晓情况的信息。在 161 名参与者中，36.0%的人知晓所有性伴侣的 HIV 感染状况。与 HIV 血清学状况未知的性伴侣发生无保护肛交行为以及仅知晓一些偶然伴侣的 HIV 血清学状况与 HIV 感染风险增加相关。相反，完全知晓所有性伴侣（包括固定性伴侣）的 HIV 感染状况与 HIV 感染发生率降低相关。与性伴侣定期就 HIV 检测结果进行沟通、诚实披露自身 HIV 感染状况以及拒绝与 HIV 血清学状况未知的性伴侣发生性接触可能会降低 MSM 感染 HIV 的风险。
