This study presented structural characteristics of a multiplex HIV transmission risk network of drug-using male sex workers (MSWs) and associates. The network comprised social, sexual, and drug-using relationships as well as affiliations with social venues. Using a sample of 387 drug-using MSWs and their male and female associates, we estimated an exponential random graph model to examine the venue-mediated relationships between individuals, the structural characteristics of relationships not linked to social venues, and homophily. Individuals affiliated with the same social venues, bars, or street intersections were more likely to have one-directional ties (weak ties) with others. Sex workers, as compared to other associates, were less likely to have reciprocated ties (strong ties) to other sex workers with the same venues. Individuals tended to have reciprocated ties not linked to venues. Partner choice tended to be based on homophily. Social venues may provide a milieu for forming weak ties in HIV transmission risk networks centered on MSWs, which may foster the efficient diffusion of prevention messages as diverse information is obtained and information redundancy is avoided.
