PrEP indicates preexposure prophylaxis.

In the United States, reducing new human immunodeficiency virus (HIV) infections will require a determined focus on primary HIV prevention among young black men who have sex with men (YBMSM), the only group in the United States where HIV incidence has increased over the past decade.1 Through 2011, effective clinic-based HIV prevention interventions that target YBMSM have been virtually nonexistent.2 In 2012, the US Food and Drug Administration approved a preexposure prophylaxis (PrEP) consisting of daily oral tenofovir disoproxil fumarate and emtricitabine. This PrEP has an estimated effectiveness of over 90%3 and, therefore, an HIV prevention effect potential for several domestic HIV epicenters.4
The south side of Chicago represents the largest contiguous black community in the United States. Despite the many assets of the south side, this community has a high HIV prevalence. uConnect is a population-based cohort study of YBMSM that examines how sociodemographic, health, behavioral, and social factors drive new methods of HIV prevention, including PrEP.
Using respondent driven sampling (RDS), 622 eligible YBMSM were recruited between June 2013 and July 2014. Study participants were eligible to be interviewed if they (1) self-identified as African American or black, (2) were born male, (3) were between 16 and 29 years of age, and (4) reported oral or anal sex with a male within the past 24 months. The sample was weighted using general probability estimates5 using the RDS package in R (R Foundation). We examined the relationship of a set of sociodemographic, health care engagement, behavioral, and social characteristics with PrEP awareness and uptake.
A final analytic sample of eligible participants (n = 622) was generated through RDS chains of up to 13 waves in length and with a median of 2 recruits per participant. The mean (SD) age of the sample was 22.7 (3.2) years. Approximately 39% of participants had high school– or general education development–level terminal education, and 79.3% reported an income of less than $20 000 per year. Nearly half (48%) of HIV-negative (PrEP-eligible) individuals reported having either some government or private health coverage.
At baseline, PrEP awareness among uConnect participants was 40.5%, and 12.1% knew others who had used PrEP. PrEP awareness remained relatively stable over the recruitment period (Figure). Approximately 72.1% of the sample was not infected with HIV, 3.6% of whom had used PrEP. Having a primary care provider, participating in an HIV prevention program or research study, having had an anorectal sexually transmitted infection test, and membership in the House and Ball community, a national network of socially organized “houses” largely comprised of YBMSM and transgender women that has existed in Chicago since the 1930s, were significantly associated with PrEP awareness (Table). Additionally, among PrEP-eligible participants, meeting with an HIV outreach worker within 12 months of being recruited to our uConnect cohort was significantly associated with PrEP awareness (adjusted odds ratio [aOR], 2.02; 95% CI, 1.29-3.16).
uConnect is the first study of diverse YBMSM-relevant characteristics and corresponding PrEP engagement from a population-based sample. Low PrEP awareness and uptake among YBMSM parallels earlier HIV treatment disparities. While PrEP is promising, this population-based cohort study illustrates that real-world PrEP use by those with the highest HIV incidence faces major implementation challenges that require purposeful and sustained engagement with black communities inclusive of their health care providers. We find that PrEP awareness is associated with a diverse range of clinical engagement activities among YBMSM. The Affordable Care Act (ACA) represents one potential opportunity to increase such clinical engagement. However, ACA benefits are not recognized in all regions of the United States, and in our cohort, only half of the participants had any type of health care coverage. Ongoing work should include scientific assessment of strategies to mobilize networks of YBMSM around PrEP as part of a comprehensive health care program. Concomitantly, efforts to mitigate the structural barriers that prevent PrEP uptake among YBMSM may greatly improve the public health effect potential of this promising HIV prevention intervention.
