Who Can I Ask? Who Would I Tell? An Egocentric Network Analysis Among a Sample of Women At-Risk to Explore Anticipated Advice Seeking and Disclosure Around Pre-exposure Prophylaxis (PrEP)

The Impact of Providers as Health Discussants on Black Women's Interest in PrEP for HIV Prevention

This study sought to examine the role of providers as health discussants (HD) on interest in preexposure prophylaxis for HIV prevention in a national sample of adult Black cisgender women (N = 315). Health discussant networks, a type of social network, may be influential in HIV prevention efforts. These networks, often composed of individuals' families, have improved health utilization outcomes in other disciplines. However, health discussants in HIV prevention are understudied, especially when considering providers as network members. We conducted a cross-sectional online survey and collected socio-demographic information, sexual history, HIV concerns, PrEP attitudes, healthcare utilization, mistrust, social support, and HD information. We used descriptive statistics and logistic regression to analyze data. Associations between PrEP interest and variables were examined. We found that older, partnered, who had recent healthcare visits or health insurance were more likely to involve healthcare providers as discussants. Anticipated PrEP stigma decreased provider involvement. Among participants listing providers as discussants, there was a greater likelihood of interest in using PrEP. Our findings indicate that healthcare provider support and social factors are crucial in promoting PrEP engagement among Black women. Integrating social dynamics and positive provider-patient interactions is essential for successful PrEP implementation.

Characteristics of Individuals Seen as Sources of Social Support in Populations at Increased Risk for HIV

Access to social support from one's social network can serve as a protective factor against HIV infection; however, research exploring the availability of support in diverse populations that include high proportions of people at increased risk for HIV and the characteristics of network members associated with access to such support is limited. Multi-level dyadic analyses of social network data collected from women at risk for HIV and their network members reveal which individual and relationship characteristics of network members are associated with providing emotional, material, and/or health informational support. Results indicate that access to all three types of support was associated with a network member being a friend, a member of a participant's 'core' group, someone whose opinion matters to the respondent, and the respondent trusting them. These findings have implications for interventions designed to increase access to support among individuals at risk for HIV.

Testing the Differential Access Hypothesis That Black Kidney Transplant Candidates Perceive Social Network Access to Fewer Potential Living Donors Than White Candidates

INTRODUCTION

Many studies of Black-White disparities in living donor kidney transplantation hypothesize that they were partially due to Black-White differences in candidate social network access to healthy, willing donors. This differential access hypothesis has not been tested using directly measured social network data.

RESEARCH QUESTIONS

Do black kidney transplant candidates have perceived lower social network access to health and/or willing living donors than white candidates?

DESIGN

A cross-sectional survey that measured the social network members was collected in 2015. Black-White differences in patient counts of perceived healthy and/or willing potential donors in social networks, and individual network members' probability of being perceived healthy and/or willing, were compared using logistic and negative binomial regression models.

RESULTS

The survey included 66 kidney transplant candidates reporting on 1474 social network members at a large Southeastern US transplant center in 2015. Black and White patients had similar access to perceived healthy, likely potential donors (86% vs 87% had 1 or more, P = .92; 5.91 vs 4.13 mean counts, P = .20) and perceived healthy, agreed potential donors (56% vs 48%, P = .54; 1.77 vs 1.74, P = .97). Black patients' network members were individually more likely to be perceived healthy and likely potential donors (26% vs 21%, P = .04), and White patients' network members were more likely to have agreed (13% vs 9%, P = .03), but these differences were statistically insignificant in demographically adjusted models.

CONCLUSION

Black and White transplant candidates perceived access to similar numbers of potential donors in their social networks. This result does not support the differential access hypothesis.
