Rates of Pre-exposure Prophylaxis Use and Discontinuation Among a Large U.S. National Sample of Sexual Minority Men and Adolescents

Pre-exposure prophylaxis (PrEP) is highly effective in the prevention of HIV acquisition and was recently approved for those under 18 years of age. The primary goal of the present study was to understand the prevalence of and factors associated with PrEP use among a large sample of young and adult sexual minority men (Y/SMM). Participants came from a larger national sample of SMM. Data collected included demographics, substance use, PrEP use, and sexual risk. Participants were recruited via sexual networking/dating applications and resided in the U.S. including Puerto Rico, were at least 13 years old, self-reported being HIV-negative, and identified as male. The sample was divided into two groups: YSMM (13-24 years of age) and adult SMM (25 years of age and up). Multinomial logistic regressions examining associations with never, current, and former PrEP use were run with all variables of interest simultaneously entered into the models. Age was positively associated with both former and current PrEP use among YSMM. Additionally, YSMM who identified as gay (vs. bisexual), lived in the Northeast, Midwest, and West (vs. South), had their own health insurance (vs. those on their parent's), had recently been diagnosed with an STI, and had recently used a drug all had higher odds of being a current PrEP user compared to those that had never used PrEP. Among adult SMM, those who were older did not have higher odds of current PrEP use compared to those that had never used PrEP. Those who identified as queer (vs. gay), single, had their own or were on their partner's insurance (vs. parent's), recent condomless anal sex, recent STI diagnosis, recent drug use, and recent substance use all had higher odds of being a current PrEP user compared to those that had never used PrEP. Research is needed to address the disparities in PrEP uptake among YSMM. Interventions for PrEP access among those on their parents' insurance may also be necessary.

The Impact of Pre-Exposure Prophylaxis (PrEP) Use on Sexual Anxiety, Satisfaction, and Esteem Among Gay and Bisexual Men

Gay and bisexual men (GBM) with heightened fears of human immunodeficiency virus (HIV) acquisition have reported high levels of sexual anxiety and low sexual self-esteem. Similarly, sexual satisfaction has been reported to be lower among some GBM who rely solely on condom use as HIV prevention. We sought to explore whether pre-exposure prophylaxis (PrEP) had an impact on the sexual satisfaction, anxiety, and esteem of GBM. As part of a longitudinal cohort study of 1,071 GBM, participants reported at three time points on PrEP use and completed the Multidimensional Sexual Self-Concept Questionnaire (MSSCQ). A total of 137 GBM began taking PrEP in the 24 months following baseline. Comparing their responses during times before initiating PrEP and after, within adjusted multilevel models, there was a significant decrease in sexual anxiety (B = -0.27, p = 0.03) but no significant changes in sexual esteem or satisfaction. Our findings indicate important psychological improvements resulting from PrEP initiation. Further research should explore the potential for other psychological benefits of PrEP use among GBM.

Preferences for Sexual Health Smartphone App Features Among Gay and Bisexual Men

Given the popularity of geosocial networking applications ("apps") among gay, bisexual, and other men who have sex with men (GBMSM), this study sought to examine GBMSM's willingness to use sexual health and behavior tracking features if integrated within apps they are already using to meet sexual partners. Most GBMSM (91%) recruited on a popular app reported interest in one or more sexual health app features, including features to find LGBT-friendly providers (83%), receive lab results (68%), schedule appointment reminders (67%), chat with a healthcare provider (59%), and receive medication reminder alerts (42%). Fewer GBMSM were interested in tracking and receiving feedback on their sexual behavior (35%) and substance use (24%). Our data suggest that integrating sexual health and behavior tracking features for GBMSM who use apps could be promising in engaging them in HIV prevention interventions. Further research is needed on GBMSM's perspectives about potential barriers in using such features.

Viewing Sexually Explicit Media and Its Association with Mental Health Among Gay and Bisexual Men Across the U.S

Gay and bisexual men (GBM) have reported viewing significantly more sexually explicit media (SEM) than heterosexual men. There is evidence that viewing greater amounts of SEM may result in more negative body attitude and negative affect. However, no studies have examined these variables within the same model. A national sample of 1071 HIV-negative GBM in the U.S. participating in a larger study completed an online survey, which included measures of SEM consumption, male body attitudes, anxiety, and depression. Participants reported viewing 3 h of SEM per week, on average, and 96% of participants reported recently viewing at least some SEM. Greater consumption of SEM was directly related to more negative body attitude and both depressive and anxious symptomology. There was also a significant indirect effect of SEM consumption on depressive and anxious symptomology through body attitude. These findings highlight the relevance of both SEM on body image and negative affect along with the role body image plays in anxiety and depression outcomes for GBM. They also indicate a potential role for body image in explaining the co-occurrence of SEM consumption and negative affect. For interventions looking to alleviate negative affect for GBM, it may be important to address SEM consumption and body image as they are shown to be associated with both anxious and depressive symptomology.

Sexually Explicit Media and Condomless Anal Sex Among Gay and Bisexual Men

Gay and bisexual men (GBM) have reported viewing significantly more sexually explicit media (SEM) than heterosexual men. There is some evidence that SEM depicting bareback anal sex may be linked to engagement in condomless anal sex (CAS) and thus HIV/STI transmission among GBM. A nationwide sample of HIV-negative GBM in the U.S. completed an online survey that included measures on SEM consumption (both overall frequency and percentage viewed depicting bareback sex) and reported on CAS in the past 3 months. Data showed that there was no main effect for the frequency of SEM watched in association on either the number of CAS acts with casual partners or the probability of engaging in CAS during a casual sex event. However, there was an interaction between amount of SEM consumed and percentage of bareback SEM consumed on both outcomes, such that men who reported both a high frequency of SEM consumption and a high percentage of their SEM being bareback reported the highest levels of risk behavior. These findings highlight the role that barebacking depicted in SEM may play in the normalization of sexual risk behaviors for GBM. Interventions looking to target the role SEM may play in the lives of GBM should examine what variables may help to mediate associations between viewing SEM and engaging in risk behavior.

Familiarity with and Preferences for Oral and Long-Acting Injectable HIV Pre-exposure Prophylaxis (PrEP) in a National Sample of Gay and Bisexual Men in the U.S

We sought to determine preferences for oral versus long-acting injectable (LAI) PrEP among gay and bisexual men (GBM). We surveyed a national U.S. sample of 1071 GBM about forms of PrEP. LAI PrEP was found to be acceptable among 43.2 % of men when injected monthly compared with 53.6 % of men when injected every 3 months. When asked to choose between forms of PrEP, 46.0 % preferred LAI, 14.3 % oral, 21.7 % whichever was most effective, 10.1 % had no preference, and 7.8 % would not take PrEP. There were no differences in PrEP preferences by race/ethnicity, income, region of residence, or relationship status. Those unwilling to take PrEP were significantly older than those who preferred LAI PrEP and those who would take either. Those who preferred the most effective form were younger, had less education, and reported more recent club drug use. Those who reported condomless anal sex and those who thought they were good PrEP candidates were more willing to take PrEP. Long-term health and side effects were of the greatest concern for both LAI and oral PrEP. The availability of LAI PrEP has the potential to increase uptake among GBM. The results of ongoing clinical trials of LAI PrEP will need to demonstrate similar or greater efficacy as daily Truvada for uptake to be maximized.

Changes in Familiarity with and Willingness to Take Preexposure Prophylaxis in a Longitudinal Study of Highly Sexually Active Gay and Bisexual Men

PURPOSE

For gay and bisexual men (GBM), research suggests that familiarity with preexposure prophylaxis (PrEP) has been increasing since being approved by the United States Food and Drug Administration in 2012. However, it is less clear how willingness to start using PrEP has changed over time. Likewise, some have expressed concerns regarding the potential for risk compensation (i.e., reduced condom use) were one to start PrEP; however, again, it is unclear how risk compensation may have changed over time.

METHODS

We conducted baseline and 12-month assessments with 158 highly sexually active HIV-negative GBM in New York City who were assessed between 2011 and 2014. We examined change over time both between participants (based on when they entered the study), as well as within each participant (over the 12 months of his involvement).

RESULTS

Familiarity with PrEP increased over time (both between and within participants); however, willingness to take PrEP did not change (neither between nor within participants). Few men believed taking PrEP would cause their condomless anal sex (CAS) to increase and this did not change over time. However, a majority believed PrEP would increase temptation for CAS, and this did not change over time within participants. Sexual compulsivity symptomology was associated with higher willingness to take PrEP and perceiving that PrEP would increase one's temptations for CAS. Furthermore, recent CAS was associated with greater willingness to take PrEP, a perception that PrEP would increase one's likelihood to engage in CAS, and a perception that being on PrEP would increase one's temptation for CAS.

CONCLUSIONS

Participants became more familiar with PrEP over time; however, willingness to start PrEP did not change, and this may serve as an opportunity for providers to discuss PrEP with their patients. Men who engaged in CAS were interested in PrEP and preexisting patterns of sexual behavior may be the primary determinant of CAS while on PrEP.

Recruiting a U.S. national sample of HIV-negative gay and bisexual men to complete at-home self-administered HIV/STI testing and surveys: Challenges and Opportunities

We describe enrollment for the One Thousand Strong panel, present characteristics of the panel relative to other large U.S. national studies of gay and bisexual men (GBM), and examine demographic and behavioral characteristics that were associated with passing enrollment milestones. A U.S. national sample of HIV-negative men were enrolled via an established online panel of over 22,000 GBM. Participants (n = 1071) passed three milestones to join our panel. Milestone 1 was screening eligible and providing informed consent. Milestone 2 involved completing an hour-long at-home computer-assisted self-interview (CASI) survey. Milestone 3 involved completing at-home self-administered rapid HIV testing and collecting/returning urine and rectal samples for gonorrhea and chlamydia testing. Compared to those who completed milestones: those not passing milestone 1 were more likely to be non-White and older; those not passing milestone 2 were less likely to have insurance or a primary care physician; and those not passing milestone 3 were less educated, more likely to be bisexual as opposed to gay, more likely to live in the Midwest, had fewer male partners in the past year, and less likely to have tested for HIV in the past year. Effect sizes for significant findings were small. We successfully enrolled a national sample of HIV-negative GBM who completed at-home CASI assessments and at-home self-administered HIV and urine and rectal STI testing. This indicates high feasibility and acceptability of incorporating self-administered biological assays into otherwise fully online studies. Differences in completion of study milestones indicate a need for further investigation into the reasons for lower engagement by certain groups.

Willingness to Take PrEP and Potential for Risk Compensation Among Highly Sexually Active Gay and Bisexual Men

Once-daily Truvada (Emtricitabine/Tenofovir) as a method of pre-exposure prophylaxis (PrEP) is one of the most promising biomedical interventions to eliminate new HIV infections; however, uptake among gay, bisexual, and other men who have sex with men has been slow amidst growing concern in popular/social media that PrEP use will result in reduced condom use (i.e., risk compensation). We investigated demographic, behavioral, and psychosocial differences in willingness to use PrEP as well as the perceived impact of PrEP on participants' condom use in a sample of 206 highly sexually active HIV-negative gay and bisexual men. Nearly half (46.1 %) said they would be willing to take PrEP if it were provided at no cost. Although men willing to take PrEP (vs. others) reported similar numbers of recent casual male partners (<6 weeks), they had higher odds of recent receptive condomless anal sex (CAS)-i.e., those already at high risk of contracting HIV were more willing to take PrEP. Neither age, race/ethnicity, nor income were associated with willingness to take PrEP, suggesting equal acceptability among subpopulations that are experiencing disparities in HIV incidence. There was limited evidence to suggest men would risk compensate. Only 10 % of men who had not engaged in recent CAS felt that PrEP would result in them starting to have CAS. Men who had not tested for HIV recently were also significantly more likely than others to indicate willingness to take PrEP. Offering PrEP to men who test infrequently may serve to engage them more in routine HIV/STI testing and create a continued dialogue around sexual health between patient and provider in order to prevent HIV infection.
