Review of high-risk sexual behaviors in men who have sex with men: influencing factors and theoretical models / 上海交通大学学报（医学版）

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.
