Predictors of Willingness to Diffuse PrEP Information within Ego-Centric Networks of Women Who Inject Drugs.

Journal Article (Journal Article)

Little is known about how social networks among women who inject drugs (WWID) can be leveraged to increase awareness about pre-exposure prophylaxis (PrEP). We tested the hypothesis that interpersonal characteristics influence willingness of WWID to communicate PrEP information with peers. Forty WWID ≥ 18 years completed social network surveys. Participants named on average 9.3 (SD = 3.3) network members, resulting in 375 unique relationships. WWID were willing to share PrEP information with 83% of network members. Participants had higher odds of willingness to share information within relationships when the network member was female, homeless and perceived to be at risk for HIV. Among relationships with family members and transactional sex clients, stronger emotional closeness was associated with higher odds of willingness to share information. Peer interventions where WWID share PrEP information with peers may be an efficient approach to increase PrEP awareness among this vulnerable population.
