摘　　要：目的 了解成都市男男性行为(men who have sex with men,MSM)特征,探讨MSM安全套使用知行分离的影响因素,为制定针对性的干预措施提供科学依据。方法 2023年8月在成都市开展调查。由同伴干预志愿者向符合调查要求的MSM同伴发出调查邀请,采用问卷星软件开展网络调查。问卷内容包括人口学特征、艾滋病知识知晓情况、性行为特征、暴露前后预防知晓程度及使用情况和接受HIV防治服务情况等,使用非条件logistic回归分析安全套使用知行分离的影响因素。结果 共调查306名MSM者,艾滋病知识知晓平均得分(7.22±0.98)分(满分为8分),知晓率达到95.10%。纳入知行分离分析的MSM者277名,知行分离发生率为38.99%。多因素logistic回归分析显示,姻状状况为在婚/同居(OR=8.163,95%CI:1.949~34.189)、使用过毒品(OR=2.693,95%CI:1.388~5.225)的MSM者发生知行分离的可能性更大;年龄为25~34岁(OR=0.286,95%CI:0.120~0.684)、性取向为双性恋(OR=0.162,95%CI:0.041~0.633)、比较了解Pr EP(OR=0.169,95%CI:0.031~0.913)的MSM者发生知行分离的可能性更小。结论 成都市MSM安全套使用知行分离情况较严重,应根据MSM者知行分离的特征,探索精准干预模式,减少艾滋病的传播和流行。Objective To understand the characteristics of MSM(men who have sex with men)in Chengdu and explore the fac-tors influencing the disconnect between knowledge and behavior regarding condom use,providing a scientific basis for targeted intervention measures.Methods A survey was conducted in Chengdu in August 2023.Peer intervention volunteers invited eli-gible MSM participants to participate in the survey,which was conducted online using Questionnaire Star software.The ques-tionnaire included demographic characteristics,awareness of HIV knowledge,sexual behavior characteristics,awareness and usage of pre-exposure and post-exposure prophylaxis,and access to HIV prevention and treatment services.Non-conditional logistic regression analysis was used to identify the factors influencing the disconnect between knowledge and behavior regard-ing condom use.Results A total of 306 MSM were surveyed,with an average score of 7.22±0.98 for HIV knowledge(out of a maximum of 8),resulting in an awareness rate of 95.10%.Among the MSM included in the analysis of knowledge-behavior dis-connect,277 individuals were assessed,with a disconnect rate of 38.99%.Multivariate logistic regression analysis indicated that MSM who were married or cohabitating(OR=8.163,95%CI:1.949-34.189)and those who had used drugs(OR=2.693,95%Cl:1.388-5.225)were more likely to experience a disconnect;conversely,MSM aged 25-34(OR=0.286,95%Cl:0.120-0.684),those identifying as bisexual(OR=0.162,95%CI:0.041-0.633),and those with a better understanding of PrEP(OR=0.169,95%CI:0.031-0.913)were less likely to experience this disconnect.Conclusion The disconnect between knowledge and behavior regarding condom use among MSM in Chengdu is significant.It is essential to explore precise intervention models based on the characteristics of this disconnect to reduce the transmission and prevalence of HIV.
