Objectives: To explore the Impact of community subculture of men who have sex with men (MSM) on the occurrence of high-risk sexual behavior based on the health belief model.
Methods: A qualitative research method was used to conduct in-depth interviews with 17 MSM by one-to-one and half-structured way, and thematic analysis was used to analyze the data.
Results: There were several factors for high-risk sexual behavior in MSM subculture, such as trust, subjective assessment for partner or personal health status, the role in inserting, awareness of HIV infection among partners, perception of HIV and homosexual discrimination, difficulty in maintaining a fixed partner, family responsibility,and so on. Self-efficacy also affected MSM's high-risk sexual behavior.
Conclusions: High-risk sexual behavior in MSM population is influenced by individual, group, and intra-circle subculture. Cognitive bias for HIV infection in MSMs can be intervened by constructing a preventive intervention model for high-risk sexual behavior.
目的: 基于健康信念模型探讨男男性行为者(men who have sex with men，MSM)社群亚文化对其高危性行为发生的影响。方法: 采用质性研究方法对17名MSM进行一对一的半结构式访谈，并采用主题分析法对访谈资料进行分析。结果: 在MSM社群亚文化中存在很多引起MSM高危性行为的因素，包括信任、对性伴侣或个人健康状况的主观评估、主动充当插入角色、知晓性伴侣是否感染HIV、对HIV感染严重性的感知和同性恋相关歧视、很难固定一个性伴侣及家庭责任感等；且自我效能感也影响MSM的高危性行为。结论: MSM人群中高危性行为受到社群亚文化的影响，对于预防HIV存在认知偏差，可针对相应的社群亚文化因素构建MSM高危性行为预防干预模式。.
