Abstract
This qualitative rapid ethnographic study identifies, describes and classifies the impact of sociostructural domains and their factors on men who have sex with men (MSM) HIV transmission risk. Included are the perceptions of HIV risk by four MSM subgroups: HIV positive, Latino, black, and young (aged 18 to 24). Results classify participant-perceived MSM transmission factors into sociostructural domains (e.g., social, health, economic, political, and mental health). Included in the article is a discussion of domain factors perceived as suitable for systemic intervention including addressing social stigma and discrimination, promoting MSM health and sexual health, and preventing and treating substance use. A review of study limitations and recommendations for future research conclude this article.
