摘要： 男男性行为者（ men have sex with men，MSM）因其易发生高危性行为，特别是无保护性肛交（ unprotected anal intercourse， UAI）等，成为艾滋病干预的重点人群。 MSM高危性行为的影响因素主要包括个人因素、环境因素、社会心理因素等。目前广泛应用的艾滋病行为干预理论模型主要包括知信行模型、健康信念模式、合理行为理论、社会网络理论等，这些经典模型为研究各类影响因素以及阐述 MSM高危性行为的发生提供了参考意义。未来可以整合 MSM人群高危性行为的各类影响因素，探索并构建更综合的模型，以便预测其最终行为的发生，为未来有效预防与干预该人群的高危性行为提供新思路。

Abstract:
The disproportionately high prevalence of HIV among men who have sex with men (MSM) is associated with the prevalence of unprotected anal intercourse (UAI), which has been the predominant high-risk behavior of HIV acquisition and transmission. MSM have become a target population for HIV prevention. The aspects affecting the high-risk sexual behaviors of MSM mainly include personal factors, environmental factors, and social psychological factors. Currently widely applied models of acquired immunodeficiency syndrome (AIDS) behavioral intervention include KABP (knowledge, attitude, belief, and practice) model, health belief model, theory of reasoned action, social network theory, and so on. These theories provide a reference for studying various influential factors and elaborating the occurrence of high-risk sexual behaviors of MSM. Exploring and building the comprehensive model and integrating the influencing factors of high-risk sexual behaviors of MSM can help us to predict their ultimate actions in the future. Similarly, it will also provide ideas for the further preventions and interventions in MSM.
Key words: men who have sex with men (MSM), high-risk sexual behavior, unprotected anal intercourse (UAI), theoretical model
