Abstract
Background
Complex systems theory recognizes the intricacy of health issues and inequities, which permits the study of interrelationships across multiple levels of the socioecological model. We interrogated the research to identify upstream and downstream factors, their intersections, and recursive processes to develop a visualization of HIV risk among sexual minority men.
Methods
Using global HIV literature drawn from diverse disciplines and geographies, we elucidated HIV risk factors through a complex systems theory approach. We used thematic analysis to categorize HIV risk factors into different levels of the socioecological model, such as policies, community risk factors, individual behaviors, etc. We also identified the relationships between these risk factors to assess how they shaped HIV risk. The analyses were used to inform the connections between the various factors that lead to HIV risk in order to develop a visualization of the complex system, for which Stella Architecture was used.
Results
The thematic analysis of the literature and complex systems visualization portrays that HIV risk arises from a complex interplay of recursive and reinforcing factors ranging from policies, community factors, healthcare systems, and interpersonal relationships leading to manipulations in individual-level behaviors that put sexual minority men at risk for HIV. This visual representation indicates that HIV risk cannot simply be thought of as an individual-level factor nor simply related to sexual behaviors. Rather, HIV risk arises from upstream societal forces such as stigma, poor mental health, and health systems that relate to a multitude of downstream factors that socially pattern sexual minority men’s HIV risk.
Conclusions
The risk of HIV among sexual minority men stems from numerous intersecting factors across multiple levels of the socioecological model indicating the need to improve structural- and community-oriented approaches to address HIV.
Key messages
HIV risk arises from multiple social determinants. HIV preventions need to encompass multi-level interventions to fully address HIV risk.
