“…These findings add to the burgeoning literature on social networks and PrEP, which has primarily focused on men. [13][14][15]22,23 These findings also have important implications for the development and implementation of social network-based approaches to HIV prevention for women, particularly women experiencing IPV.…”

Background: In the U.S., women represent less than 5% of all pre-exposure prophylaxis (PrEP) users. Social networks may promote and/or inhibit women's PrEP awareness, which could influence PrEP intentions. Further, women experiencing intimate partner violence (IPV) may have smaller, less supportive networks, which could deter or have no impact on PrEP care engagement. This study examined associations between network characteristics and women's PrEP awareness, interest, uptake, and perceived candidacy; and analyzed IPV as an effect modifier.Setting/Methods: From 2017 to 2018, data were collected from a prospective cohort study of 218 PrEP-eligible women with (n=94) and without (n=124) IPV experiences in Connecticut. Women completed surveys on demographics, IPV, social networks, and PrEP care continuum outcomes.Results: Adjusted analyses showed that PrEP awareness related to having more PrEP-aware alters. PrEP intentions related to having more alters with favorable opinions of women's potential PrEP use and a smaller network size. Viewing oneself as an appropriate PrEP candidate related to having more PrEP-aware alters and more alters with favorable opinions of women's potential PrEP use. IPV modified associations between network characteristics and PrEP care. Having members who were aware of and/or used PrEP was positively associated with PrEP care engagement for *

“…In addition to adding new types of social ties and interactions to FOAF, we ascribe to each entity new features or attributes. These attributes were extracted from the ADD (Adolescent to Adult) Health project survey forms [14] and from YMAP (Young Men's Affiliation Project of HIV Risk and Prevention Venue) [15], a project that examines the social networks of minority Young Men Who Have Sex with Men (YMSM). These two projects are large-scale public health research projects that include a wide range of health-related variables in order to understand disease transmission and social behavior.…”

Background Dyadic-based social networks analyses have been effective in a variety of behavioral- and health-related research areas. We introduce an ontology-driven approach towards social network analysis through encoding social data and inferring new information from the data. Methods The Friend of a Friend (FOAF) ontology is a lightweight social network ontology. We enriched FOAF by deriving social interaction data and relationships from social data to extend its domain scope. Results Our effort produced Friend of a Friend with Benefits (FOAF+) ontology that aims to support the spectrum of human interaction. A preliminary semiotic evaluation revealed a semantically rich and comprehensive knowledge base to represent complex social network relationships. With Semantic Web Rules Language, we demonstrated FOAF+ potential to infer social network ties between individual data. Conclusion Using logical rules, we defined interpersonal dyadic social connections, which can create inferred linked dyadic social representations of individuals, represent complex behavioral information, help machines interpret some of the concepts and relationships involving human interaction, query network data, and contribute methods for analytical and disease surveillance.

“…Both venue-level and individual-level data were collected annually through staff-administered interviews. For more details, see elsewhere (Fujimoto, Cao, Kuhns, Li, & Schneider, 2018; Fujimoto et al, 2017) and the online supplement. The study protocol was approved by institutional review boards at each site.…”

Many younger Black men who have sex with men (YBMSM) are exposed to homonegativity, societal stigma, and racial discrimination in their social environment. This study uses a social network modeling methodology to identify aspects of the social environment that are not often described, that is, the places and spaces or “venues” where YBMSM socialize or where they receive HIV prevention services. In particular, we identify the structural features of avoidance of these venues as an indicator of negative experiences, using bipartite exponential random graph models. Our study theorizes that YBMSM avoid certain venues en masse through information diffusion among social network members. We specify two social mechanisms of collective venue avoidance—(1) homophily (i.e., ego–alter similarity in venue avoidance) and (2) popular opinion leaders (as early adopters)—and test the corresponding hypotheses that (Hypothesis 1) socially connected individuals avoid venues together and that (Hypothesis 2) popular individuals would be more likely to avoid venues. Based on data collected from YBMSM aged 16 to 29 years between 2014 and 2016 in Houston, Texas ( N = 227) and Chicago, Illinois ( N = 241), results indicate that Hypothesis 1 was supported in both cities but that Hypothesis 2 was supported only in Chicago. The findings suggest that the structural patterns of venue avoidance are different between cities and may inform dissemination of prevention messages and delivery of venue- and social influence–based HIV interventions.
