目的 了解成都市男男性行为（MSM）人群HIV检测情况,分析MSM HIV检测意愿的影响因素,为成都市MSM 人群HIV传播控制提供依据。方法 于2018年5月—2020年5月,采用互联网招募MSM人群,以某某男男同性恋交友软件为研究对象,开展网络问卷调查,最终130例MSM接受调查。采用自行设计问卷调查MSM的艾滋病知晓率情况和基本特征、最近6个月口交/肛交性行为、近1年HIV检测以及HIV检测意愿等情况。结果 最终收集有效问卷125份,MSM人群HIV总知晓率为95.20%（119/125）。最近1年HIV检测比例为48.80%（61/125）,HIV抗体阳性检出率为12.00%（15/125）,其中1年未做过HIV检测者HIV抗体阳性检出率 18.75%（12/64）高于1年中做过检测者4.92%（3/61）（P<0.05）,65.60%（82/125）具有明确的检测意愿;多因素分析发现,初次性行为年龄≥30岁、知晓HIV、通过线上寻找伴侣、近6个月发生同性肛交、近1年接受艾滋病预防服务、未向家人表露同性恋身份、过去12个月内有性病检测史为MSM HIV定期检测意愿的促进因素（P<0.05）,自认为所生活的区域MSM人群感染HIV风险低、近6个月性交时使用安全套频率低为MSM定期检测意愿的阻碍因素（P<0.05）。结论 成都市MSM人群 HIV认知及定期检测率和检测意愿偏低,建议针对影响因素,重点加强行为干预,动员MSM参加HIV定期检测,扩大HIV检测覆盖面。

Influencing factors of HIV cognition and testing willingness of men who have sex with men in Chengdu

Objective To study HIV testing willingness of men who have sex with men (MSM) in Chengdu , and their influencing factors, we provide the basis for the control of MSM HIV transmission in Chengdu. Methods MSM were recruited through the Internet between May 2018 and May 2020, and a total of 130 cases of MSM from an online gay dating software were enrolled in the network questionnaire survey. The AIDS awareness questionnaire was used to assess HIV cognition, and self-designed questionnaires were used to investigate basic characteristics of this group, self-reported oral/anal sex behaviors in the last 6 months, HIV testing in the last year, testing willingness, etc. Results Totally 125 valid questionnaires were collected. The overall HIV awareness rate in the MSM population was 95.20% (119/125). It was found that the HIV detection rate in the last year was 48.80% (61/125), and the positive detection rate of HIV antibody was 12.00% (15/125). Besides, the positive detection rate of HIV antibody in men who had not been tested for HIV in the last year was 18.75% (12/64), higher than 4.92%(3/61) in those who had been tested (P<0.05), and 65.60% (82/125) had clear willingness to receive test. Multi-factor analysis found that having first sexual behaviour at a young age≥30 years old, knowledge of HIV, searching for a partner online, same-sex anal sex in the past 6 months, receiving AIDS prevention services in the past 1 year, hiding homosexuality from family members, and history of STD testing in the past 12 months were motivators for the willingness of MSM to receive regular test for HIV (P<0.05). Believing in the low risk of HIV infection among MSM people in the area where they live, and the low frequency of using condoms during sexual behavior in the past 6 months were obstructive factors for regular testing willingness (P<0.05). Conclusion MSM people in Chengdu have low HIV awareness, low regular testing rate, and low willingness to test. It is recommended to focus on strengthening behavioral interventions based on these influencing factors, and mobilize MSM to participate in regular HIV testing, thereby expanding the scope of HIV testing.
