Increasing the uptake of pre-exposure prophylaxis (PrEP) to prevent HIV acquisition among at-risk populations, such as young men who have sex with men (YMSM), is of vital importance to slowing the HIV epidemic. Stigma and negative injunctive norms, such as the so called "Truvada Whore" phenomenon, hamper this effort. We examined the prevalence and types of PrEP stigma and injunctive norm beliefs among YMSM and transgender women and associated individual and geospatial factors. A newly created measure of PrEP Stigma and Positive Attitudes was administered to 620 participants in an ongoing longitudinal cohort study. Results indicated lower stigma among White, compared to Black and Latino participants, and among participants not identifying as male. Prior knowledge about PrEP was associated with lower stigma and higher positive attitudes. PrEP stigma had significant geospatial clustering and hotspots were identified in neighborhoods with high HIV incidence and concentration of racial minorities, whereas coldspots were identified in areas with high HIV incidence and low LGBT stigma. These results provide important information about PrEP attitudes and how PrEP stigma differs between individuals and across communities.

Background: Despite high efficacy, use of pre-exposure prophylaxis (PrEP) remains low among young men who have sex with men (MSM) and transgender women (TW), primarily because of barriers such as stigma and resource awareness. We evaluated a social marketing campaign known as PrEP4Love that works to eliminate PrEP stigma; and awareness gaps through targeted advertising. Setting: Chicago, Illinois. Methods: Participants were enrolled within a cohort study of young MSM and TW (RADAR). Data were collected between June 2017 and April 2018 from HIV-negative individuals attending a follow-up visit. Surveys assessed demographics, PrEP attitudes and perceptions, and PrEP4Love campaign awareness. Associations between PrEP4Love awareness and PrEP perceptions, uptake, and behaviors were assessed using multiple logistic regression controlling for age, race/ethnicity, gender, sexual identity, and ever having used PrEP. Results: Of 700 participants, the majority (75.9%) indicated seeing PrEP4Love ads in Chicago. Those who had seen ads were more likely to be out to their providers (odds ratio = 1.95; 95% confidence interval: 1.17 to 3.23) than those who had not, and those who had conversations were significantly more likely to have initiated the conversation themselves. Individuals who had seen ads were more likely to have taken PrEP in the last 6 months (odds ratio = 1.87; 95% confidence interval: 1.15 to 3.16) and more likely to believe their friends and the general public approved of and used PrEP. Conclusion: Social marketing campaigns are promising interventions that have the potential to alleviate barriers to HIV prevention, particularly among MSM and TW. Future research should evaluate the impact of these initiatives at multiple time points.

BackgroundIn 1988, 1 of 3 women (W) and heterosexual men living with human immunodeficiency virus (HIV) reported wanting children, but little is known about parenting desires of men who have sex with men (MSM) living with HIV. We examined parenting desires among persons initiating antiretroviral therapy (ART).MethodsOf 1809 participants in the AIDS Clinical Trials Group (ACTG) Study 5257, 1425 W aged ≤45 years or men completed questionnaires about parenting desires at baseline and 96 weeks after initiating ART. Self-reported desires for children in the future (yes/unsure vs no) and associations between baseline sociodemographics and parenting desires at 96 weeks were examined using multivariable logistic regression, overall and within subgroups.ResultsThe 1425 participants were as follows: 36% white, 39% black, 22% Hispanic; median age 36 (interquartile range, 28–44); 70% MSM, 13% men reported sex only with W (MSW), 17% W. At baseline, 42% may want children in the future (42% MSM, 37% MSW, 43% W); at 96 weeks, 41% may want children (41% MSM, 37% MSW, 43% W). At follow-up, approximately 10% of responses changed in each direction. In multivariable analyses, education greater than high school, <30 years, and having no children were significantly associated with future parenting desires among all subgroups. Among MSM, being black was associated with desiring children.ConclusionsApproximately 40% of MSM, W, and MSW with HIV may want children, both at baseline and 96 weeks after ART initiation. These results highlight the need to regularly assess parenting goals, provide access to comprehensive reproductive services, and address prevention of vertical and heterosexual HIV transmission.

Background: HIV intervention activities directed toward both those most likely to transmit and their HIV-negative partners have the potential to substantially disrupt HIV transmission. Using HIV sequence data to construct molecular transmission clusters can reveal individuals whose viruses are connected. The utility of various cluster prioritization schemes measuring cluster growth have been demonstrated using surveillance data in New York City and across the United States, by the Centers for Disease Control and Prevention (CDC). Methods:We examined clustering and cluster growth prioritization schemes using Illinois HIV sequence data that include cases from Chicago, a large urban center with high HIV prevalence, to compare their ability to predict future cluster growth. Results:We found that past cluster growth was a far better predictor of future cluster growth than cluster membership alone but found no substantive difference between the schemes used by CDC and the relative cluster growth scheme previously used in New York City (NYC). Focusing on individuals selected simultaneously by both the CDC and the NYC schemes did not provide additional improvements. Conclusion:Growth-based prioritization schemes can easily be automated in HIV surveillance tools and can be used by health departments to identify and respond to clusters where HIV transmission may be actively occurring.
