Perceived likelihood of using HIV pre-exposure prophylaxis medications among young men who have sex with men

Understanding the impact of women's correct risk perception on human immunodeficiency virus diagnosis: Insights from South Africa

BACKGROUND

South African women have the highest burden of HIV infections globally. We investigated the temporal trends and the impact of key factors associated with HIV diagnosis among a nationally representative cohort of South African women.

METHODS

Total of 24,657 women who participated in the National HIV, Behaviour and Health Surveys conducted from 2002-to-2017.

RESULTS

Despite decades-long prevention efforts, we observed a significant increase in HIV prevalence over time (22% in 2002 to 21% in 2005-2008 and 29% in 2012-2017). Overall, 46% of the women living with HIV were not aware of their risk of HIV with age-specific disparities. Our findings revealed compelling evidence between HIV seropositivity and high HIV risk-perception (adjusted Odds Ratio (aOR):1.47 to 3.29) which increased overtime and exceeded the other factors. At a population-level, 45% of the HIV diagnoses were exclusively associated with women who believed they were at risk of HIV in 2012-2017. Women who reported using condoms at last sexual act were also at increased risk of HIV infection, with a population attributable risk of 18% (2002) to 21% (2012-2017).

CONCLUSION

There is an urgent need for culturally, socially, and linguistically appropriate prevention and awareness campaigns with realistic, non-confrontational messages.

Correlates of Transactional Sex Among Black Men and Women Who Misuse Opioids

The rise in opioid misuse coincides with increased sexually transmitted infection (STI) and HIV incidence. Transactional sex is an under-researched phenomenon among Black Americans who misuse opioids, and may increase their risk of STI or HIV transmission. Given the disproportionate impact of the opioid epidemic on Black Americans and the risks associated with opioid misuse, the current study aims to investigate sociostructural factors, history of violence, and sexual risk factors associated with transactional sex among Black men and women. A sample of n = 375 Black adult Kentuckians reporting opioid misuse completed a survey including transactional sex, sociostructural, violence history, and sexual risk measures. Results of chi-squares and independent samples t-tests revealed that compared to men who did not report engaging in transactional sex, men who engaged in transactional sex were less educated, reported being sexually assaulted or having an unwanted sexual experience in their lifetime, and were more likely to use opioids or cocaine before or during sex in the last year. Women who engaged in transactional sex had a history of violence, more structural barriers, higher psychological distress, and engaged in more sexual risk behaviors compared to women who did not engage in transactional sex. Implications for future research and interventions with this population are discussed.

Factors Associated with the Awareness of and Willingness to Use HIV Pre-exposure Prophylaxis Among Gay, Bisexual, and Other Men Who Have Sex with Men, Baltimore, MD, 2017-2019

Pre-exposure prophylaxis (PrEP) is an effective tool in protecting persons from acquiring HIV infection through sex or injection drug use. However, awareness and willingness to use PrEP among Black gay, bisexual, and other men who have sex with men (BMSM) remain suboptimal compared to White MSM (WMSM) in the United States. Our aims were to (1) assess the factors associated with PrEP awareness and willingness to use PrEP among MSM and (2) compare the PrEP perceptions among BMSM versus non-Black MSM. Data were drawn from two cross-sectional behavioral surveys in Baltimore, MD: Behavioral Surveillance Research (BESURE) conducted in 2017, and Safe Spaces 4 Sexual Health (SS4SH), conducted in 2018 and 2019. Descriptive statistics were used to summarize the study population. We used Poisson regression models to identify variables associated with awareness of PrEP and willingness to use PrEP. PrEP perceptions were assessed via 13 items scored on a 5-point Likert scale. Finally, we conducted a post-hoc exploratory bivariate analysis of the relationship between PrEP perception and willingness to use PrEP, stratified by race/ethnicity. A total of 261 MSM participated in this study. Many of the participants were aware of PrEP (75.1%). Factors associated with greater PrEP awareness included having greater than a high school education (aRR 1.22, 95% CI 1.04, 1.43); and earning more than $25,000 annually (aRR 1.24, 95% CI 1.08, 1.42). Participants who had received money in exchange for sex one or more times were less likely to be aware of PrEP (aRR 0.59, 95% CI 0.36, 0.95). More than half of the participants were willing to use PrEP (55.3%). In bivariate and multivariable analyses, demographic or behavioral characteristics were not significantly associated with willingness to use PrEP. Higher agreement with the following statements was associated with lower willingness to use PrEP: "Having to take a pill every day is difficult" (RR 0.89, 95% CI 0.82-0.97) and, "I am concerned about the side effects of PrEP" (RR 0.89, 95% CI 0.82-0.96), and "PrEP is for people who have riskier sex lives than I do" (RR 0.86, 95% CI 0.78-0.95). Conversely, higher willingness to use PrEP was associated with comfortable having sex without a condom (RR 1.11, 95% CI 1.02-1.21), less anxious about sex (RR 1.12, 95% CI 1.02-1.24), and my friends think that I should take PrEP (RR 1.19, 95% CI 1.07-1.32). We found BMSM compared to non-Black MSM had higher mean scores related to taking a daily pill (p = 0.041), concerns about side effects (p = 0.012), concerns about people thinking they had HIV (p = 0.001), concerns about the financial costs of PrEP (p = 0.038) and caution when dealing with healthcare organizations/medical mistrust (p = 0.019). Perceptions with a statistically significant lower score among BMSM versus non-Black MSM included statements such as, comfortable having sex without a condom (p = 0.003) and less anxious about sex (p < 0.001). We conclude HIV prevention strategies, programs, and interventions should be cognizant of PrEP perceptions that facilitate or hinder PrEP uptake in Baltimore City, MD.

Substance use and variation in sexual partnership rates among young MSM and young transgender women: Disaggregating between and within-person associations

BACKGROUND

Substance use has been extensively linked to sexual behavior and HIV/STI risk among men who have sex with men (MSM) and transgender women (TW). However, the impact of specific substances and on specific partnership types is not well characterized. The current study seeks to estimate the association between specific substances and partnership rates while carefully disaggregating between and within-person associations to characterize the nature of these associations and inform prevention interventions.

METHODS

Using data from a longitudinal cohort (n = 1159) of young MSM (YMSM) and young TW (YTW), we utilized a series of hybrid mixed effect models to estimate the associations between substance use (i.e., heavy episodic drinking [HED], marijuana, cocaine, ecstasy, methamphetamine, poppers, prescription stimulant, prescription painkiller, and prescription depressants) and partnerships (i.e., one-time, casual, and main).

RESULTS

Results from multivariable models indicated people using substances had higher one-time (HED, poppers) and casual (HED, methamphetamine, poppers) partnership rates. In addition, participants reported higher rates of one-time (HED, ecstasy, methamphetamine, poppers) and casual partners (HED, marijuana, cocaine, methamphetamines, poppers) during periods of substance use.

CONCLUSION

These findings confirm that the highest rates of sexual activity occur among YMSM-YTW using substances during periods of substance use. Yet, these findings should caution researchers against simplistic generalizations as these associations differ across substance and partnership types. Efforts to promote the health of MSM-YTW who use substances should carefully consider this complexity as interventions accounting for the unique cultural context of substance use in these populations are most likely to be successful.

Knowledgeable, aware / interested: Young black women's perceptions of pre-exposure prophylaxis

Purpose

HIV in the United States disproportionately affects young Black women. Pre-exposure prophylaxis (PrEP) is an effective HIV prevention option that has the potential to reduce HIV incidence among HIV-vulnerable populations. However, data regarding women's awareness, interest in starting, and feelings of acceptability or stigma about PrEP remains limited, particularly among adolescent and young Black women.

Materials and methods

A cross-sectional survey was conducted with 100 sexually active young Black women ages 13–24 years attending women's health clinics in Chicago, IL. Descriptive statistics were used to characterize the sample and determine more about what the PrEP needs and barriers are in this community. Associations were modeled using logistic regression and 95% confidence intervals for both bivariate and multivariable models.

Results

In our survey (N = 100), half of study participants (50%) expressed interest in starting PrEP in the next three months and a majority (80%) of young women were confident they could obtain PrEP. Pregnant young women were significantly more interested in starting PrEP than non-pregnant women [OR 2.3 95% CI (1.0, 5.4)], p = 0.05), however, this association did not remain significant in adjusted models.

Conclusions

This study provides a more complete understanding of awareness, interest in, and acceptability of PrEP among adolescent and young Black women attending women's health clinics. Findings indicate sustained interest in starting PrEP, reduced stigma, and increased awareness of PrEP among young Black women. These findings suggest that integrating PrEP into women's health clinics is a promising strategy to increase awareness and utilization of PrEP and decrease HIV transmission among youth at highest risk.

Perspectives on Social Support and Stigma in PrEP-related Care among Gay and Bisexual Men: A Qualitative Investigation

Despite its effectiveness at preventing HIV, uptake of PrEP has been slow. PrEP-related stigma is a potential barrier to uptake. Social support has been found to buffer against some PrEP stigma. Unfortunately, little research has investigated the relationship between social support and PrEP-related care. In 2018, we conducted 20 semistructured interviews with MSM who use PrEP (ages 22-70). Interview questions explored social support and PrEP-related stigma, and how these and other psychosocial factors affected PrEP use and continuation. Data were analyzed using grounded theory. Social support was important in PrEP-related care and promoted adaptive behavioral responses, such as adherence to PrEP-related medical care and enhancing resilience to stress. Participants described psychosocial benefits of PrEP, such as reduced HIV-related anxiety, but some also reported that PrEP-related stigma was an additional stressor. Findings suggest that social support has significant impacts within PrEP-related care and may help buffer against stigma.

Underlying factors related to HIV/AIDS prevention: investigating the willingness to take pre-exposure prophylaxis among men-who-have-sex-with-men in Germany

BACKGROUND

This study investigates the willingness of men-who-have-sex-with-men (MSM) to use HIV pre-exposure prophylaxis (PrEP). Research in the HIV/AIDS field typically relies on clinical and epidemiological studies, thereby often excluding social dimensions of the illness as well as factors explaining its prevention. The current study analyzes HIV-prevention through an interdisciplinary theoretical approach. It aims to comprehensively understand the mechanisms associated with the willingness to take PrEP among MSM in terms of psychological, social, behavioral, cultural, and demographic factors.

METHODS

We analyze data from the survey "Gay Men and AIDS" conducted in Germany in 2013 prior to market approval for PrEP. Analyses were performed using the statistical software SPSS 25.0, while results were visualized using the R programming language.

RESULTS

We find that perceived risk of infection, social norms (anticipated HIV-stigma), practices (e.g. regular condomless sex), and socio-demographic factors (young age, being single) all have a positive effect on the willingness to take PrEP, while education reveals a negative, and income no effect.

CONCLUSIONS

Results indicate that beyond well-established socio-psychological mechanisms of health behavior, social factors play a crucial role in understanding the willingness of PrEP uptake. This study enriches existing health behavior theories with sociological concepts such as social norms and social practices.

Temporal Variation in One-Time Partnership Rates Among Young Men Who Have Sex With Men and Transgender Women

BACKGROUND

Volatility in sexual contact rates has been recognized as an important factor influencing HIV transmission dynamics. One-time partnerships may be particularly important given the potential to quickly accumulate large number of contacts. Yet, empirical data documenting individual variation in contact rates remain rare. This study provides much needed data on temporal variation in one-time partners to better understand behavioral dynamics and improve the accuracy of transmission models.

METHODS

Data for this study were obtained from a longitudinal cohort study of young men who have sex with men and transgender women in Chicago. Participants provided sexual network data every 6 months for 2 years. A series of random effects models examined variation in one-time partnership rates and disaggregated within and between associations of exposure variables. Exposure variables included prior number of one-time partners, number of casual partners, and having a main partner.

RESULTS

Results indicated substantial between-person and within-person variation in one-time partners. Casual partnerships were positively associated and main partnerships negatively associated with one-time partnership rates. There remained a small positive association between prior one-time partnerships and the current number of one-time partnerships.

CONCLUSIONS

Despite the preponderance of a low number of one-time partners, substantial variation in one-time partnership rates exists among young men who have sex with men and transgender women. Accordingly, focusing on high contact rate individuals alone may be insufficient to identify periods of highest risk. Future studies should use these estimates to more accurately model how volatility impacts HIV transmission and better understand how this variation influences intervention effectiveness.

Pre-Exposure Prophylaxis Care Continuum, Barriers, and Facilitators among Black Men Who Have Sex with Men in the United States: A Systematic Review and Meta-Analysis

Pre-exposure prophylaxis (PrEP) represents a viable HIV prevention tool for black men who have sex with men (BMSM). However, aggregated evidence regarding the presentations and determinants of the PrEP continuum (e.g., awareness, willingness, intention, uptake and adherence) remains absent to empirically inform future intervention efforts. We meta-analytically summarized the prevalence and qualitatively synthesized key barriers/facilitators of the stages of the PrEP continuum among a pooled sample of 42,870 BMSM aggregated from 56 published studies. Our random-effect models indicated a pooled prevalence of PrEP awareness (50.8%, 95% CI: 43.6-58.0%, willingness/intention (58.2%, 95% CI: 52.0-68.1%) and uptake (15.5%, 95% CI: 12.8-18.2%). Qualitative summary revealed that perception of HIV risk, intersectional/PrEP-related stigma and medical mistrust were among the most quoted factors that influence PrEP use. BMSM remain underrepresented in key stages of the PrEP continuum. Futures interventions are continuously needed to target multilevel barriers/facilitators to enhance the PrEP continuum among BMSM.

Decrease in prevalence but increase in frequency of non-marijuana drug use following the onset of the COVID-19 pandemic in a large cohort of young men who have sex with men and young transgender women

BACKGROUND

Substantial concern exists regarding the impact of the COVID-19 pandemic on substance use behaviors. This is especially true for subpopulations like young men who have sex with men and young transgender women (YMSM-YTW) who report higher rates of substance use. This study examines changes in prevalence and frequency of marijuana and non-marijuana drug use among YMSM-YTW following the onset of the pandemic.

METHOD

Data for this analysis (n = 458 participants, 1356 observations) come from an ongoing longitudinal cohort study of YMSM-YTW. A series of Bayesian multilevel models were used to examine change in prevalence and frequency of use for marijuana and non-marijuana drugs.

RESULTS

Results indicated no systematic change in prevalence or frequency of marijuana use. However, a decrease in non-marijuana drug use was observed (OR = 0.60, 95 % CrI: [0.37, 0.94]) following the onset of the pandemic. Furthermore, a small increase in the frequency of non-marijuana drug use was observed (OR = 1.79, 95 % CrI: [1.02, 3.21]) among individuals who used these substances.

CONCLUSIONS

These findings concur with a small number of studies identifying a decrease in drug use prevalence but increase in frequency among those who continue to use drugs. Despite the protective effect of lower drug use prevalence, higher frequency of use may lead to additional negative health outcomes of drug use, particularly among groups facing multiple health challenges such as YMSM-YTW. However, the pandemic likely has a unique impact on substance use behaviors across subpopulations.

Estimated proportion of an urban academic emergency department patient population eligible for HIV preexposure prophylaxis

OBJECTIVE

Pre-exposure prophylaxis (PrEP) is a highly effective but underutilized method of HIV prevention. Emergency departments (EDs) have access to at-risk populations meeting CDC eligibility criteria for PrEP. Characterizing this population could help motivate, develop, and implement ED interventions to promote PrEP uptake.

METHODS

This cross-sectional study explored the proportion of patients from an urban, academic ED who met CDC 2017 PrEP eligibility criteria using three existing datasets that mimic patient selection strategies for HIV screening: 1) study of consecutively approached ED patients from 2008 to 2009 (analogous to non-targeted screening), 2) patients of the ED's HIV screening program in 2017 (analogous to risk-targeted screening), and 3) electronic health record (EHR) diagnostic codes in 2017 (analogous to EHR selected screening). The primary outcome was the proportion eligible for PrEP referral. Secondary outcomes included proportion by risk group: men who have sex with men (MSM), heterosexual men and women (HMW), and persons who inject drugs (PWID).

RESULTS

The proportion eligible for PrEP was: 568/1970 (28.8%, 95% CI: 26.9-30.9) for consecutively approached patients, 552/3884 (14%, 95% CI: 13-15) for risk-targeted patients, and 605/66287 (0.9%, 95% CI: 0.8-1.0) for EHR diagnoses of all patients. For the two datasets with behavioral risk information, the proportion eligible was: MSM 1-2%, HMW 12-28%, and PWID 1-4%.

CONCLUSIONS

A large subgroup of this ED population was eligible for PrEP referral. EDs are a compelling setting for development and implementation of HIV prevention interventions to assist in national efforts to expand PrEP.

Sexual Agreements Among Young Sexual and Gender Minorities Assigned Male at Birth: Associations with Relationship Quality and Break-Up

Previous studies have shown that sexual non-monogamy is not associated with lower relationship satisfaction among adult male same-sex couples and may therefore be a viable alternative to monogamy. However, sexual minority men with non-monogamous agreements have reported lower commitment and trust in their relationships than those with monogamous agreements-potentially raising their risk of break-up. In this study, we investigated whether sexual agreements (monogamous, non-monogamous, or no sexual agreement) were associated with relationship quality and rates of break-up over 1 year in a sample of 338 young sexual and gender minorities assigned male at birth (SGM-AMAB). Participants reported their sexual agreement and indices of relationship quality (satisfaction, trust, and commitment) at baseline, as well as their relationship status (intact or broken up) at 6- and 12-month follow-up. Results showed no significant differences by sexual agreement in concurrent trust, but participants with monogamous agreements reported higher satisfaction and commitment than those with non-monogamous agreements or no sexual agreement. Despite these significant differences in relationship quality, there were no significant differences in rates of break-up at 6- or 12-month follow-up across the sexual agreement types. However, having a monogamous agreement was indirectly associated with lower rates of break-up through relationship commitment. Although results were mixed, findings provide some preliminary support that young SGM-AMAB in relationships with monogamous agreements may have higher satisfaction and commitment at early relationship stages, and that monogamous agreements may be a protective factor against break-up over 1 year through the mechanism of relationship commitment.

Willingness to initiate pre-exposure prophylaxis (PrEP) and its use among opioid-dependent individuals in drug treatment

BACKGROUND

People who use drugs (PWUD) continue to experience a disproportionate HIV burden due to drug- and sex-related risk behaviors. Pre-exposure prophylaxis (PrEP) is highly effective at preventing HIV infection, but very little is known about PrEP use among PWUD and their willingness to initiate PrEP.

METHODS

We conducted a cross-sectional survey among 234 HIV-negative, opioid-dependent individuals recruited from an urban methadone clinic. Participants were assessed using an audio-computer assisted self-interview technique. Bivariate and multiple logistic regressions were used to explore independent correlates of actual PrEP use and willingness to initiate PrEP.

RESULTS

One-fourth (25.6 %) of participants had previously used PrEP. Over two-thirds (67.1 %) of participants had previously heard of PrEP, and 65.0 % were willing to take it. In multivariable logistic regression analyses, the number of times participants engaged in HIV testing (aOR = 1.66, p < 0.01) and whether they visited a healthcare provider (aOR=20.81, p = 0.02) were associated with a higher likelihood of PrEP use, while perceived HIV risk (aOR=2.71, p < 0.01) and previous use of PrEP (aOR=3.57, p < 0.01) were significantly associated with willingness to initiate PrEP.

CONCLUSION

PrEP use was low among PWUD, but their willingness to initiate PrEP was moderate, which indicated a significant discrepancy between actual PrEP use and willingness to use it. Our findings highlight the importance of healthcare providers engaging opioid-dependent individuals in discussions about PrEP and the need for innovative strategies to increase their awareness of PrEP and modify their perceptions of HIV risk.

Geospatial perspectives on health: The PrEP4Love campaign and the role of local context in health promotion messaging

Pre-exposure prophylaxis (PrEP) remains one of the most effective biomedical interventions for the prevention of HIV transmission. However, uptake among populations most impacted by the HIV epidemic remains low. La rge-scale awareness and mobilization campaigns have sought to address gaps in knowledge and motivation in order to improve PrEP diffusion. Such campaigns must be cognizant of the historical, physical, and structural contexts in which they exist. In urban contexts, neighborhood segregation has the potential to impact health outcomes and amplify disparities. Therefore, we present novel geospatial approaches to the evaluation of a Chicago-based PrEP messaging campaign (PrEP4Love) in a 2018 cohort of men who have sex with men and transgender women, contextualizing results within the localized infrastructure and public health landscape, and examining associations between geographic location and campaign efficacy. Results revealed notable variance in rates of PrEP uptake associated with campaign exposure by Chicago planning area, which are likely explained by the historical and contemporary impacts of racist structures on physical environment and city infrastructure. Findings have important implications for the evaluation and implementation of future messaging campaigns, which should take the unique historical, structural, and geospatial factors of their particular settings into account in order to achieve maximum impact.

PrEP4Love: The Role of Messaging and Prevention Advocacy in PrEP Attitudes, Perceptions, and Uptake Among YMSM and Transgender Women

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.

Role of Social and Sexual Network Factors in PrEP Utilization Among YMSM and Transgender Women in Chicago

Despite demonstrated efficacy, uptake of HIV pre-exposure prophylaxis (PrEP) remains low, particularly among high-risk demographics such as transgender women, Black men who have sex with men (BMSM), and young MSM (YMSM). Research thus far has largely focused on individual factors that may impede PrEP uptake in these demographics, leaving social network factors relatively unexplored. The present study used data collected from participants within RADAR, a longitudinal cohort study in Chicago focused on understanding the individual, dyadic, network, social, and biologic factors associated with HIV infection within YMSM. Of the 906 study participants who did not report an HIV diagnosis at baseline, 7.0% reported using PrEP in the prior 6 months. Recent PrEP use was associated with both individual-level (age and gender) and network-level factors (mean relationship strength, sexual network degree, etc.). These findings highlight the need to expand beyond focusing on individual-level drivers of PrEP uptake, as well as changing our understanding of who is most important within a network (centrality vs. strength of weak ties). Future work is needed to determine whether variables associated with PrEP uptake are similarly connected to PrEP adherence.

An Exploration of Pre-exposure Prophylaxis (PrEP) Initiation Among Women Who Inject Drugs

Pre-exposure prophylaxis (PrEP) is an effective but understudied tool for preventing HIV among women who inject drugs (WWID). This article is the first to explore WWID's rationale for PrEP initiation (or refusal) in a real-world setting. Purposive sampling was used to recruit 25 WWID, participating in a PrEP demonstration project operating within a syringe services program, based on whether they initiated or declined PrEP care. Content analysis of qualitative interviews was used to explore decisions to initiate PrEP (or not). We found that WWID view HIV as severe, perceive themselves to be susceptible to HIV, and believe PrEP is beneficial for HIV prevention. For some, however, real and perceived barriers outweighed benefits, leading to decisions not to initiate PrEP. Barriers included HIV stigma, fear of side effects, and needing assurance that PrEP care will be available long-term. Despite viewing PrEP as an important HIV prevention tool, not all WWID who were offered PrEP initiated it. For these women, supports to buffer perceived barriers to initiation and access to post-exposure prophylaxis may be warranted. For women who initiate, it is possible that adherence will wane if perceived risk does not remain high. Research to understand PrEP persistence is needed.

A Web-Based Intervention to Reduce Decision Conflict Regarding HIV Pre-Exposure Prophylaxis: Protocol for a Clinical Trial

Background

HIV pre-exposure prophylaxis (PrEP) is recommended for populations at high ongoing risk for infection. There are noted racial disparities in the incidence of HIV and other sexually transmitted infections (STIs) for African, Caribbean, and Canadian Black (ACB, black) populations in Ontario, Canada. Although blacks represent only 4.7% of the Ontario population, they account for 30% of HIV prevalence and 25% of new infections in the province. The existing clinical public health practice toolkit has not been sufficient to optimize PrEP uptake, despite the overwhelming evidence of PrEP’s efficacy for reducing HIV transmission risk. Since its establishment as an effective HIV prevention tool, the major focus in behavioral research on PrEP has been on understanding and improving adherence. To date, there is no known formalized intervention in place designed to support ACB men and women at high risk of making high-quality decisions regarding the adoption of PrEP as an HIV prevention practice.

Objective

We propose 2 aims to address these gaps in HIV prevention and implementation science. First, the Ottawa Decision Support Framework (ODSF) for use in the PrEP decisional needs of black patients was adapted. Second, the decision support intervention to estimate effect size compared with control conditions in reducing decision conflict and predicting adherence over 60 days was pilot tested.

Methods

In aim 1, we propose a cross-sectional qualitative descriptive study using data collected from key informant interviews with eligible PrEP patients (n=30) and surveys with health professionals (n=20) involved in HIV PrEP management. Data obtained from aim 1 will be used to develop a decision support intervention based on the ODSF. In aim 2, the adopted decision support intervention using a block-randomized design to estimate effect size compared with control conditions in reducing decision conflict and predicting adherence over 60 days was pilot tested. Hypothesis testing will be de-emphasized in favor of generating effect size estimates.

Results

A research award was funded on March 25, 2017 (Multimedia Appendix 1). Ethical approval was received on March 25, 2019 (with supplemental approval received on May 10, 2019). Data collection started on April 9, 2019. As of September 30, 2019, we enrolled 29 patients and 24 health care providers for aim 1. We are currently analysing the data collected for aim 1. Aim 2 is scheduled to start in May 2020.

Conclusions

This study will provide evidence-based information on the decisional needs of black patients who are at risk of HIV and have been offered PrEP. The study will also test the effect of decision support intervention in reducing decision conflict, adoption of PrEP, and adherence to PrEP.

Adherence to PrEP Among Young Men Who Have Sex With Men Participating in a Sexual Health Services Demonstration Project in Alameda County, California

BACKGROUND

Young men of color who have sex with men face a continual increase in rates of HIV infection. Pre-exposure prophylaxis (PrEP) is an important prevention method for these young men.

SETTING

The Connecting Resources for Urban Sexual Health (CRUSH) demonstration project provided sexual health services, including PrEP, to young men who have sex with men aged 18-29 years. We report on adherence and factors influencing it.

METHODS

Participants were offered HIV and sexually transmitted infection testing, prevention counseling, PrEP, and when appropriate, sexually transmitted infection treatment and postexposure prophylaxis. Participants taking PrEP had erythrocyte tenofovir diphosphate and emtricitabine levels measured through dried blood spot testing at 4, 12, and 24 weeks to estimate medication adherence. Participants also completed surveys to assess demographic and psychosocial measures.

RESULTS

From February 2014 to November 2015, CRUSH enrolled 257 participants. Ninety-three percent started PrEP, 81% of whom initiated it at their first visit. Twelve percent required postexposure prophylaxis before starting PrEP. Adherence at protective levels was initially high with 87% demonstrating levels consistent with at least 4 doses per week at week 4, compared with 77% at the 48-week follow-up. African American race, exposure to violence, and having survival needs were associated with significantly lower levels of adherence [odds ratio (OR): 0.33; confidence interval (CI): 0.11 to 0.97, P < 0.04; OR: 0.79; CI: 0.59 to 1.04, P < 0.10; OR: 0.51; CI: 0.24 to 1.05, P < 0.07].

CONCLUSIONS

Most young men who initiate PrEP adhere at levels that confer protection against HIV infection. Interventions should account for differences in life experiences, particularly addressing the structural challenges facing young African American men.

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.

How heterogeneous are MSM from Brazilian cities? An analysis of sexual behavior and perceived risk and a description of trends in awareness and willingness to use pre-exposure prophylaxis

Background

Brazil has the largest population of individuals living with HIV/AIDS in Latin America, with a disproportional prevalence of infection among gays, bisexuals and other men who have sex with men (MSM). Of relevance to prevention and treatment efforts, Brazilian MSM from different regions may differ in behaviors and risk perception related to HIV.

Methods

We report on MSM living in 29 different cities: 26 Brazilian state capitals, the Federal District and two large cities in São Paulo state assessed in three web-based surveys (2016–2018) advertised on Grindr, Hornet and Facebook. Using logistic regression models, we assessed the association of risk behavior with HIV perceived risk as well as factors associated with high-risk behavior.

Results

A total of 16,667 MSM completed the survey. Overall, MSM from the North and Northeast were younger, more black/mixed-black, of lower income and lower education compared to MSM from the South, Southeast and Central-west. Though 17% had never tested for HIV (with higher percentages in the North and Northeast), condomless receptive anal sex (previous 6 months) and high-risk behavior as per HIV Incidence Risk scale for MSM were observed for 41 and 64%, respectively. Sexual behavior and HIV perceived risk had low variability by city and high-risk behavior was strongly associated with high HIV perceived risk. Younger age, being gay/homosexual, having a steady partner, binge drinking, report of sexually transmitted infection (STI) and ever testing for HIV were associated with increased odds of high-risk behavior. Awareness and willingness to use PrEP increased from 2016 to 2018 in most cities.

Conclusions

Overall, MSM socio-demographic characteristics were heterogeneous among Brazilian cities, but similarities were noted among the cities from the same administrative region with a marked exception of the Federal District not following the patterns for the Central-West. Combination HIV prevention is most needed among young men who self-identify as gay/homosexual, report binge drinking or prior STI.

The PrEP Care Continuum and Black Men Who Have Sex with Men: A Scoping Review of Published Data on Awareness, Uptake, Adherence, and Retention in PrEP Care

Pre-exposure prophylaxis (PrEP) has demonstrated high efficacy to reduce HIV infections, however, racial/ethnic HIV disparities continue among black MSM. The purpose of this review was to assess available data to inform interventions to increase PrEP awareness, uptake, and adherence among black MSM. Of the 3024 studies retrieved, 36 met final inclusion criteria and were categorized into the PrEP care continuum: (1) awareness (n = 16), (2) uptake (n = 9), and (3) adherence (n = 12). Only 26 of the studies presented analytical findings by race/ethnicity. Key barrier themes included cost, HIV-related stigma, and fear of potential side effects. A key facilitator theme identified by black MSM included gaining PrEP awareness from social and sexual networks. There are significant gaps in research on black MSM and PrEP utilization, especially regarding PrEP uptake and adherence. These data are needed to inform interventions to address current inequities in PrEP services, to help improve care outcomes for black MSM.

Factors Associated with PrEP Support and Disclosure Among YMSM and Transgender Individuals Assigned Male at Birth in Chicago

Pre-exposure prophylaxis (PrEP) is one of the best biomedical HIV prevention tools available. However, uptake, particularly in communities of men who have sex with men (MSM) and transgender individuals assigned male at birth (AMAB), remains low. Further, the role of an individual's social support structure on PrEP uptake and adherence remains largely understudied. Understanding MSM and AMAB transgender individuals' perceptions of PrEP use as well as support and patterns of disclosure of (or intent to disclose) their PrEP status may offer key insights into how best to improve uptake in vulnerable communities. Further, the influence of one's social connections on other factors, such as perceptions of and conversations about PrEP deserves attention as well, as these factors may be key to improved knowledge and uptake. Therefore, we assessed perceptions of PrEP use, disclosure of or intent to disclose PrEP status, and social support and associated factors among a cohort of MSM and AMAB transgender individuals in a large Midwestern city. Results demonstrated that, among those not taking PrEP, bisexual participants and those unsure of their sexual identity were less likely to be comfortable with the idea of disclosing PrEP use were they ever to start taking it. Encouragingly however, we found that individuals who reported disclosing their PrEP status had high rates of support among friends and relatives. We also observed that knowing someone else who was on PrEP was associated with increased likelihood of discussing PrEP with one's medical provider, as was increased age. Other findings and implications for research, policy, and practice are discussed within.

Acceptability and Barriers to HIV Pre-Exposure Prophylaxis in Atlanta's Adolescents and Their Parents

Adolescents aged 13-24 years account for 23% of new HIV infections in Atlanta, indicating need for better HIV prevention strategies in this population. Pre-exposure prophylaxis (PrEP) is now approved for adolescent use. This study aims to understand the acceptability of and barriers to PrEP in adolescents and parents. We administered PrEP acceptability and barrier measures to HIV(-) 13-17 year olds and their parents from January to April 2016 in an adolescent clinic and emergency department in Atlanta, GA, stratifying by adolescent sexual activity. Acceptability scores (AS) and barrier scores (BS) were calculated by averaging survey answers 1-3. For AS, 1 was very unlikely to accept PrEP; concomitantly, BS near 3 indicated fewer barriers. Two-sample hypothesis testing, Pearson correlations, and linear regression were used. Of the 102 adolescent/parent dyads, 67% of adolescents were female, 94% black, with a mean age of 15.7 ± 1.5 years, and 31% were sexually active. Parents were 94% female, 96% black, with a mean age of 42.4 ± 8.9 years. AS averaged between somewhat to very likely to accept PrEP (2.4 ± 0.5 and 2.2 ± 0.6) in adolescents and parents, respectively. BS averaged between unlikely and somewhat likely to perceive barriers to PrEP (2.0 ± 0.4 and 1.9 ± 0.5) in adolescents and parents, respectively. The adolescent/parent dyad is likely to accept PrEP, regardless of sexual activity. Limitations include that nearly 70% of adolescents were not sexually active, and the study was conducted before PrEP approval by the Food and Drug Administration for those who are younger than 18 years. These results support future parent and adolescent education on PrEP.

Acceptability and Feasibility of Self-Collecting Biological Specimens for HIV, Sexually Transmitted Infection, and Adherence Testing Among High-Risk Populations (Project Caboodle!): Protocol for an Exploratory Mixed-Methods Study

BACKGROUND

Men who have sex with men (MSM) in the United States experience a disproportionate burden of HIV and bacterial sexually transmitted infections (STIs), such as gonorrhea and chlamydia. Screening levels among MSM remain inadequate owing to barriers to testing such as stigma, privacy and confidentiality concerns, transportation issues, insufficient clinic time, and limited access to health care. Self-collection of specimens at home and their return by mail for HIV and bacterial STI testing, as well as pre-exposure prophylaxis (PrEP) adherence monitoring, could be a resource-efficient option that might mitigate some of these barriers.

OBJECTIVE

Project Caboodle! is a mixed-methods study that explores the acceptability and feasibility of self-collecting and returning a bundle of 5 different specimens for HIV and bacterial STI testing, as well as PrEP adherence monitoring, among sexually active HIV-negative or unknown status MSM in the United States aged 18 to 34 years.

METHODS

Participants will be recruited using age, race, and ethnicity varied advertising on social networking websites and mobile gay dating apps. In Phase 1, we will send 100 participants a box containing materials for self-collecting and potentially returning a finger-stick blood sample (for HIV testing), pharyngeal swab, rectal swab, and urine specimen (for gonorrhea and chlamydia testing), and hair sample (to assess adequacy for potential PrEP adherence monitoring). Specimen return will not be incentivized, and participants can choose to mail back all, some, or none of the specimens. Test results will be delivered back to participants by trained counselors over the phone. In Phase 2, we will conduct individual in-depth interviews using a video-based teleconferencing software (VSee) with 32 participants from Phase 1 (half who returned all specimens and half who returned some or no specimens) to examine attitudes toward and barriers to completing various study activities.

RESULTS

Project Caboodle! was funded in May 2018, and participant recruitment began in March 2019. The processes of designing a study logo, creating advertisements, programming Web-based surveys, and finalizing step-by-step written instructions accompanied by color images for specimen self-collection have been completed. The boxes containing 5 self-collection kits affixed with unique identification stickers are being assembled, and shipping procedures (for mailing out boxes to participants and for specimen return by participants using prepaid shipping envelopes) and payment procedures for completing the surveys and in-depth interviews are being finalized.

CONCLUSIONS

Self-collection of biological specimens at home and their return by mail for HIV and bacterial STI testing, as well as PrEP adherence monitoring, might offer a practical and convenient solution to improve comprehensive prevention efforts for high-risk MSM. The potentially reduced time, expense, and travel associated with this approach could facilitate a wider implementation of screening algorithms and remote monitoring strategies.

Structural Barriers to Pre-exposure Prophylaxis Use Among Young Sexual Minority Men: The P18 Cohort Study

BACKGROUND

Despite decreasing rates of HIV among many populations, HIV-related health disparities among gay, bisexual and other men who have sex with men persist, with disproportional percentages of new HIV diagnoses among racial and ethnic minority men. Despite increasing awareness of HIV pre-exposure prophylaxis (PrEP), PrEP use remains low. In addition to exploring individual-level factors for this slow uptake, structural drivers of PrEP use must also be identified in order to maximize the effectiveness of biomedical HIV prevention strategies.

METHOD

Using cross-sectional data from an ongoing cohort study of young sexual minority men (N=492), we examine the extent to which structural-level barriers, including access to health care, medication logistics, counseling support, and stigma are related to PrEP use.

RESULTS

While almost all participants indicated awareness of PrEP, only 14% had ever used PrEP. PrEP use was associated with lower concerns about health care access, particularly paying for PrEP. Those with greater concerns talking with their provider about their sexual behaviors were less likely to use PrEP.

CONCLUSION

Paying for PrEP and talking to one's provider about sexual behaviors are concerns for young sexual minority men. In particular, stigma from healthcare providers poses a significant barrier to PrEP use in this population. Providers need not only to increase their own awareness of and advocacy for PrEP as an effective risk-management strategy for HIV prevention, but also must work to create open and non-judgmental spaces in which patients can discuss sexual behaviors without the fear of stigma.

Sexual Networks of Racially Diverse Young MSM Differ in Racial Homophily But Not Concurrency

BACKGROUND

Substantial racial disparities exist in HIV infection among young men who have sex with men (YMSM). However, evidence suggests black YMSM do not engage in greater levels of risk behavior. Sexual networks may help explain this paradox. This study used egocentric exponential random graph models to examine variation in concurrency (ie, 2 or more simultaneous partners) and homophily (ie, same race/ethnicity partners) across race/ethnicity groups in a diverse sample of YMSM.

METHODS

Data for this study come from a longitudinal cohort study of YMSM. Participants (n = 1012) provided data regarding their sexual contacts during the 6 months before their first study visit. A series of egocentric exponential random graph models examined how providing separate estimates for homophily and concurrency parameters across race/ethnicity improved the fit of these models. Networks were simulated using these parameters to examine how local network characteristics impact risk at the whole network level.

RESULTS

Results indicated that homophily, but not concurrency, varied across race/ethnicity. Black participants witnessed significantly higher race/ethnicity homophily compared with white and Latino peers. Extrapolating from these models, black individuals were more likely to be in a connected component with an HIV-positive individual and closer to HIV-positive individuals. However, white individuals were more likely to be in large connected components.

CONCLUSIONS

These findings suggest that high racial homophily combined with existing disparities in HIV help perpetuate the spread of HIV among black YMSM. Nonetheless, additional work is required to understand these disparities given that homophily alone cannot sustain them indefinitely.

Perceived Versus Calculated HIV Risk: Implications for Pre-exposure Prophylaxis Uptake in a Randomized Trial of Men Who Have Sex With Men

BACKGROUND

Inaccurate HIV risk perception by men who have sex with men is a barrier to HIV prevention. Providing information about objective HIV risk could improve pre-exposure prophylaxis (PrEP) uptake.

METHODS

PrEP Accessibility Research & Evaluation 2 (PrEPARE2) was a randomized controlled trial of men who have sex with men to determine whether an objective risk score affects future PrEP uptake. Participants completed a baseline survey to assess demographics, risk behaviors, and HIV self-perceived risk (SPR). The survey generated a calculated HIV risk (CalcR) score, estimating HIV risk based on reported condomless anal intercourse and sexually transmitted infections, and was provided to individuals in the intervention arm. Participants were contacted 8 weeks later to determine whether they initiated PrEP.

RESULTS

Of 171 participants (median age 32 years; 37% Hispanic or non-Hispanic Black; median 5 sexual partners in the past 6 months), 81% had heard of PrEP, and 57% believed they were good PrEP candidates. SPR had poor agreement with CalcR (kappa = 0.176) with 38% underestimating their HIV risk. At week 8, only 14 of 135 participants had initiated PrEP with no difference between arms (CalcR 11%, control 10%, P > 0.99). The most common reason for not starting PrEP was low HIV risk perception. There was a relative decrease in SPR over time (P = 0.06) but no difference between arms (P = 0.29).

CONCLUSION

Providing an objective HIV risk score alone did not increase PrEP uptake. HIV testing performed at testing sites may be a crucial time to correct misperceptions about risk and initiate same-day PrEP, given enthusiasm for PrEP on the testing day to facilitate greater uptake.

Associations between perceived barriers and benefits of using HIV pre-exposure prophylaxis and medication adherence among men who have sex with men in Western China

BACKGROUND

To investigate the associations between the perceived barriers and benefits of using HIV pre-exposure prophylaxis medication, including worries about the side effects, disliking taking drugs, perceived burden of taking medication, positive expectations as to the efficacy of the drugs, favourable doctor-patient relationships, and medication adherence among men who have sex with men (MSM) to provide a target for improving medication adherence and reducing HIV infection among MSM.

METHODS

MSM were recruited in western China from April 2013 to October 2014, administered oral tenofovir (TDF) daily and followed up every 12 weeks for 2 years. At each follow-up, the medication rate was calculated based on the self-reported number of missed doses over 2 weeks, and then, the medication adherence was evaluated. The barriers and benefits perceived during medication were obtained by a self-administered questionnaire, and their effects on medication adherence were analysed by linear mixed models.

RESULTS

A total of 411 participants were enrolled in this study, and 1561 follow-up observation points were obtained. The average medication rate was 0.62 ± 0.37, and the medication rate increased with longer follow-up (P < 0.05). The medication rate was higher among MSM who were divorced (compared to those who were unmarried, P < 0.0001). MSM with more positive expectations as to the efficacy of the drugs showed higher rates of medication (P < 0.0001), while those who were more worried about side effects had a lower medication rate (P = 0.0208). In contrast, the dislike of taking the drugs and the burden perceived during medication had no effects on the actual medication rate of taking TDF (P > 0.05).

CONCLUSION

How to obtain and maintain high medication adherence among MSM is the key to the PrEP intervention strategy for effective reduction of HIV infection. For MSM in China, we should deepen their understanding of the effectiveness and safety of PrEP and increase their confidence in PrEP, thereby improving their medication adherence.

Why I Quit Pre-Exposure Prophylaxis (PrEP)? A Mixed-Method Study Exploring Reasons for PrEP Discontinuation and Potential Re-initiation Among Gay and Bisexual Men

Literature concerning pre-exposure prophylaxis (PrEP) among gay and bisexual identifying men (GBM) has explored facilitators and barriers to uptake and adherence. Far less reported are the reasons why GBM discontinue PrEP use. A national sample of 1071 GBM completed surveys about PrEP use and discontinuation. Participants who were still taking PrEP the 24-month follow up were compared to those that had stopped. Eighteen percent (n = 31) of GBM who reported ever using PrEP discontinued use. Younger (AOR = 0.96; 95% CI 0.92-1.00), and unemployed (AOR = 4.58; 95% CI 1.43-14.70) GBM were more likely to discontinue PrEP than their counterparts. Those that discontinued provided details on why via a free response question. The most common reasons for discontinuation were lower perceived HIV risk (50%) and cost/insurance (30%). Reasons for potential re-initiation included higher-risk sexual activities and changes to structural related barriers. More research is needed to inform interventions on how GBM can continue taking PrEP during changes to employment that effect insurance coverage and cost.

Acceptability of Antiretroviral Pre-exposure Prophylaxis from a Cohort of Sexually Experienced Young Transgender Women in Two U.S. Cities

Emtricitabine/tenofovir disoproxil fumarate as pre-exposure prophylaxis (PrEP) can prevent HIV infection among at-risk individuals, including young transgender women (YTW). We used baseline data from 230 HIV-uninfected YTW (ages 16-29 years) who were enrolled in Project LifeSkills during 2012-2015. We examined factors associated with perceived acceptability of PrEP use (mean score = 23.4, range 10.0-30.0). Participants were largely transgender women of color (67%) and had a mean age of 23 years (SD = 3.5). In an adjusted multiple linear regression model, PrEP interest (β = 3.7, 95% CI 2.2-5.2) and having a medical provider who meets their health needs (β = 2.9, 95% CI 1.3-4.4) was associated with higher PrEP acceptability scores, whereas younger age (21-25 vs 26-29 years) (β = -2.0, 95% CI - 3.6 to - 0.4) and reporting transactional sex in the past 4 months (β = - 1.5, 95% CI - 3.0 to - 0.1) was associated with lower PrEP acceptability scores (all p values < 0.05). Enhancing PrEP-related interventions by addressing the unique barriers to uptake among YTW of younger age or those with history of transactional sex could bolster PrEP acceptability for this population.

A Multilevel Tailored Web App-Based Intervention for Linking Young Men Who Have Sex With Men to Quality Care (Get Connected): Protocol for a Randomized Controlled Trial

Background

HIV epidemic among young men who have sex with men (YMSM) is characterized by strong racial disparities and concerns about the availability and access to culturally appropriate HIV prevention and care service delivery. Get Connected, a Web-based intervention that employs individual- and system-level tailoring technology to reduce barriers to HIV prevention care (eg, HIV or sexually transmitted infection [STI] testing, pre-exposure prophylaxis [PrEP]), was developed for YMSM (age 15-24 years). This protocol details the design and procedures of a 2-phase project that includes mystery shopping and a randomized controlled trial (RCT) to test the efficacy of Get Connected among YMSM in Philadelphia, Atlanta, and Houston.

Objective

The objective of mystery shopping is to examine the quality of HIV test counseling and PrEP-related referrals for YMSM within local HIV or STI testing sites. The objective of the RCT is to test the efficacy of Get Connected for increasing HIV-negative or HIV-unknown YMSM’s successful uptake of HIV prevention services (eg, routine HIV or STI testing), PrEP awareness, and likelihood to start PrEP (PrEP willingness), compared with those in the control condition, over a 12-month period.

Methods

For Phase 1, we will create a master list of HIV and STI testing sites in each city. We will enroll and train 10-15 mystery shoppers per city; each testing site will be separately visited and assessed by 2 mystery shoppers. After each site visit, the mystery shoppers will complete a site evaluation to record their perceptions of various measures including lesbian, gay, bisexual, transgender, queer visibility and inclusivity, privacy and confidentiality, provider-patient interactions, and clinic environment. For Phase 2, we will enroll 480 YMSM for 12 months across the 3 iTech cities into a 2-arm prospective RCT. Participants randomized to the control condition are directed to the AIDSVu.org testing site locator. Participants randomized to the intervention condition will be granted access to a Web app with content tailored to their specific demographic characteristics (eg, age, race or ethnicity, location, and relationship status), HIV and STI risk behaviors (eg, HIV and STI testing history, substance use, communication with partners regarding status) and sociocultural context (eg, homelessness, incarceration). Study assessments will occur at enrollment and at 1, 3, 6, 9, and 12 months postenrollment.

Results

Get Connected research activities began in September 2016 and are ongoing. To date, institutional review board (IRB) submission is complete and IRB authorization agreements are pending at several other universities.

Conclusions

The deployment of Get Connected through a mobile-optimized Web app seeks to optimize the intervention’s acceptability, accessibility, availability, and long-term affordability among YMSM.

Exploring the Use of Pre-exposure Prophylaxis (PrEP) for HIV Prevention Among High-Risk People Who Use Drugs in Treatment

Introduction: Despite unequivocal evidence supporting the use of pre-exposure prophylaxis (PrEP), its scale-up has been gradual overall, and nearly absent among people who use drugs (PWUD). In the present study, we implemented the use of PrEP, as a part of an integrated HIV prevention approach, and explored the experiences and attitudes related to PrEP use among PWUD.

Methods: Between September 2016 and July 2017, we recruited 40 HIV-uninfected, methadone-maintained people, who reported HIV-risk behaviors, and were currently taking PrEP. We conducted both quantitative and in-depth semi-structured qualitative interviews that primarily focused on experiences, attitudes, acceptability, disclosure status, risk compensation-related attitudes, and barriers related to PrEP adherence.

Results: Results showed that participants were highly satisfied and perceived PrEP as valuable and acceptable for HIV prevention. Participants reported high adherence to PrEP. The most highly endorsed facilitators to PrEP adherence were use of memory aids, no out-of-pocket cost, perceived benefit, and support from social network. The barriers to adherence included side-effects, stigmatization, requirement of daily dosing, and accessibility of PrEP services. Additionally, participants expressed disagreement with the overall risk compensation-related attitudes (i.e., decreased personal concern about engaging in HIV risk behavior due to their perception that PrEP is now fully protecting them from contracting HIV) and indicated no increased engagement in risk behaviors while on PrEP.

Conclusions: The results from the current study provide preliminary evidence supporting the successful integration of PrEP within the substance abuse treatment setting, where high risk PWUD are concentrated.

Measuring Acceptability and Preferences for Implementation of Pre-Exposure Prophylaxis (PrEP) Using Conjoint Analysis: An Application to Primary HIV Prevention Among High Risk Drug Users

Although people who use drugs (PWUD) are one of the key risk populations who could benefit from the use of pre-exposure prophylaxis (PrEP), to date, little attention has been given to incorporating PrEP into HIV prevention approaches targeting this underserved group. This study investigated the acceptability of PrEP based on a number of known PrEP attributes among high-risk PWUD in a drug treatment setting. A total of 400 HIV-negative PWUD, who reported drug- and/or sex-related risk behaviors were recruited from a methadone clinic to complete a stated preference (full-profile conjoint) survey. Participants ranked the eight hypothetical PrEP program scenarios with varied combinations of six attributes related to PrEP (cost, dosing, efficacy, side-effects, treatment setting, and frequency of HIV testing). SPSS conjoint procedure was used to estimate the relative importance of each attribute and preferences across eight possible PrEP delivery programs. PrEP acceptability ranged from 30.6 to 86.3% with a mean acceptability of 56.2% across the eight hypothetical PrEP program scenarios. The PrEP program scenario with the highest acceptability had the following attribute levels: insurance covered, daily dosing, 95% effective, no side-effects, treatment at HIV clinic, and HIV testing needed every 6 months. The cost associated with PrEP was the most important attribute (relative importance score: RIS = 38.8), followed by efficacy (RIS = 20.5) and side effects (RIS = 11.9); other attributes had no significant effect. Our findings reported a high acceptability of PrEP in response to different PrEP program scenarios with different attribute profiles. As the result of having this information, researchers and policymakers will be better equipped for evidence informed targeting and dissemination efforts to optimize PrEP uptake among this underserved population.

The Use of Online Posts to Identify Barriers to and Facilitators of HIV Pre-exposure Prophylaxis (PrEP) Among Men Who Have Sex with Men: A Comparison to a Systematic Review of the Peer-Reviewed Literature

Pre-exposure prophylaxis (PrEP) remains an under-utilized HIV prevention tool among men who have sex with men (MSM). To more comprehensively elucidate barriers and facilitators to PrEP use among US MSM, we conducted a systematic review of peer-reviewed published articles and content analysis of online posts about PrEP. We searched peer-reviewed databases (Medline, Web of Science, Google Scholar) using MESH headings and keywords about PrEP and/or HIV prevention from 2005 to 2015. We included original studies among MSM in the US that reported on barriers, facilitators, or other factors related to PrEP use. We also searched online posts and associated comments (news articles, opinion pieces, blogs and other social media posts) in diverse venues (Facebook, Slate Outward, Huffington Post Gay Voices, Queerty, and My PrEP Experience blog) to identify posts about PrEP. We used content analysis to identify themes and compare potential differences between the peer-reviewed literature and online posts. We identified 25 peer-reviewed articles and 28 online posts meeting inclusion criteria. We identified 48 unique barriers and 46 facilitators to using PrEP. These 94 themes fit into six overarching categories: (1) access (n = 14), (2) attitudes/beliefs (n = 24), (3) attributes of PrEP (n = 13), (4) behaviors (n = 11), (5) sociodemographic characteristics (n = 8), and (6) social network (n = 6). In all categories, analysis of online posts resulted in identification of a greater number of unique themes. Thirty-eight themes were identified in the online posts that were not identified in the peer-reviewed literature. We identified barriers and facilitators to PrEP in online posts that were not identified in a systematic review of the peer-reviewed literature. By incorporating data both from a systematic review of peer-reviewed articles and from online posts, we have identified salient and novel information about barriers to and facilitators of PrEP use. Traditional research approaches may not comprehensively capture current factors important for designing and implementing PrEP related interventions.

Meningitis Vaccination, Knowledge, and Awareness Among YMSM in Chicago

Serogroup C invasive meningococcal disease (IMD) outbreaks in men who have sex with men (MSM) have been occurring with greater frequency in urban areas across the United States. An effective vaccine for IMD is available and is recommended for MSM in outbreak settings. Particular subgroups of MSM have been disproportionately represented in outbreaks, specifically young, Black, and HIV-positive MSM. As little is known about the knowledge, awareness, and vaccination status of young MSM, we sought to describe this and explore racial/ethnic differences. Data were collected from an established cohort study-RADAR-of 16- to 29-year-old MSM recruited through previous cohort studies and/or by being a partner or peer of a current study member. A total of 486 young MSM (YMSM) responded to 13 IMD-related questions. Approximately half of the sample correctly identified how IMD is spread and 58.6% accurately responded that vaccination was the best prevention method; however, more than 60% of participants felt they were at no risk of getting meningitis and only 49% self-reported vaccination. Additionally, White YMSM were significantly more likely to be vaccinated and to have accurate knowledge and risk perception of IMD compared with Black YMSM. Findings have important implications for disease control, outbreak management, and intervention development.

Sexual Partner Typologies and the Association Between Drug Use and Sexual Risk Behavior Among Young Men Who Have Sex With Men

Numerous partner and relationship characteristics are associated with sexual risk behavior among young men who have sex with men (YMSM), including being in a serious relationship and having older partners. However, most research in this area is limited by its reliance on variable-centered approaches. Using multilevel latent class analysis, this study identified subgroups of sexual partner types with a particular emphasis on examining whether partner type moderated the association between drug use and condomless anal sex (CAS). Data were utilized from an ongoing cohort study of YMSM (ages 16-29) recruited from previous studies as well as peers and serious partners of existing cohort members. A total of 469 participants reported on 1596 sexual partners in the past 6 months. We identified four distinct sexual partner typologies, which we refer to as: casual, older-online, much older, and serious. Results indicated that rates of CAS were highest for older-online and serious partners. Additionally, there was a positive association between drug use and CAS among a predominantly marijuana using sample, but only for serious partners. While previous research has found that CAS is highest in serious relationships, findings suggest that there may be another type of partnership in which CAS is likely to occur (older partners met online). If confirmed, these results suggest interventions focused on the intersection of marijuana use and CAS may be particularly important among YMSM with serious partners.

Evaluating HIV Knowledge Questionnaires Among Men Who Have Sex with Men: A Multi-Study Item Response Theory Analysis

Knowledge about the transmission, prevention, and treatment of HIV remains a critical element in psychosocial models of HIV risk behavior and is commonly used as an outcome in HIV prevention interventions. However, most HIV knowledge questions have not undergone rigorous psychometric testing such as using item response theory. The current study used data from six studies of men who have sex with men (MSM; n = 3565) to (1) examine the item properties of HIV knowledge questions, (2) test for differential item functioning on commonly studied characteristics (i.e., age, race/ethnicity, and HIV risk behavior), (3) select items with the optimal item characteristics, and (4) leverage this combined dataset to examine the potential moderating effect of age on the relationship between condomless anal sex (CAS) and HIV knowledge. Findings indicated that existing questions tend to poorly differentiate those with higher levels of HIV knowledge, but items were relatively robust across diverse individuals. Furthermore, age moderated the relationship between CAS and HIV knowledge with older MSM having the strongest association. These findings suggest that additional items are required in order to capture a more nuanced understanding of HIV knowledge and that the association between CAS and HIV knowledge may vary by age.

Facilitators and Barriers to Pre-Exposure Prophylaxis Willingness Among Young Men Who Have Sex with Men Who Use Geosocial Networking Applications in California

While correlates of pre-exposure prophylaxis (PrEP) uptake have been explored among older men who have sex with men (MSM), less is known about the facilitators and barriers that encourage uptake among younger MSM (YMSM). This study explores the association between willingness to take PrEP and demographic characteristics, sexual risk, and substance use, and attitudinal factors among YMSM in California who use geosocial networking applications (GSN apps). Based on survey data from YMSM recruited through GSN apps (n = 687), PrEP willingness was positively associated with Hispanic ethnicity [adjusted odds ratio (aOR): 1.73; confidence interval (CI): 1.01-2.98; p = 0.046], concerns about drug effects (aOR: 0.46; CI: 0.33-0.65; p < 0.001), medical mistrust (aOR: 0.71; CI: 0.53-0.96; p < 0.001), and concerns about adherence (aOR: 0.65; CI: 0.49-0.89; p = 0.005). PrEP willingness was positively associated with medium (aOR: 1.87; CI: 1.14-3.07; p = 0.014) and high concern (aOR: 1.84; CI: 1.13-3.01; p < 0.001) about contracting HIV and perceived benefits of taking PrEP (aOR: 2.59; CI: 1.78-3.78; p < 0.001). In addition to emphasizing the benefits of using PrEP, campaigns that address concerns regarding adherence and side effects may increase interest in and demand for PrEP among YMSM. More opportunities are needed to educate YMSM about PrEP, including addressing their concerns about this new prevention strategy. Providers should speak openly and honestly to YMSM considering PrEP about what to do if side effects occur and how to handle missed doses. Outreach using GSN apps for PrEP education and screening may be an effective way to reach YMSM.

Adolescent pre-exposure prophylaxis for HIV prevention: current perspectives

Adolescents are a critical population that is disproportionately impacted by the HIV epidemic. More than 2 million adolescents between the age group of 10 and 19 years are living with HIV, and millions are at risk of infection. HIV risks are considerably higher among girls, especially in high-prevalence settings such as eastern and southern Africa. In addition to girls, there are other vulnerable adolescent subgroups, such as teenagers, who use intravenous (IV) drugs, gay and bisexual boys, transgender youth, male sex workers, and people who fall into more than one of these categories. Pre-exposure prophylaxis (PrEP) is a new intervention for people at high risk for acquiring HIV, with an estimated HIV incidence of >3%. Recent data from trials show evidence of the efficacy of PrEP as a powerful HIV prevention tool in high-risk populations, including men who have sex with men, HIV-1-serodiscordant heterosexual couples, and IV drug users. The reported efficacy in those trials of the daily use of oral tenofovir, alone or in combination with emtricitabine, to prevent HIV infection ranged from 44% to 75% and was heavily dependent on adherence. Despite the proven efficacy of PrEP in adult trials, concerns remain about its feasibility in real-life scenarios due to stigma, cost, and limited clinician experience with PrEP delivery. Recent studies are attempting to expand the inquiry into the efficacy of such HIV prophylaxis approaches in adolescent populations, but there are still many gaps in knowledge, and no country has yet approved it for use with adolescents. The aim of this review was to identify and summarize the evidence from studies on PrEP for adolescents. We have compiled and reviewed published studies focusing on safety, feasibility, adherence to therapeutics, self-perception, and legal issues related to PrEP in people aged between 10 and 24 years.

Potential Healthcare Insurance and Provider Barriers to Pre-Exposure Prophylaxis Utilization Among Young Men Who Have Sex with Men

Young adult men-who-have-sex-with-men (YMSM) continue to have among the highest incidence of HIV infection in the United States. Pre-exposure prophylaxis (PrEP) is an effective and safe method of preventing HIV infection; however, despite US Food and Drug Administration approval, utilization remains low, in part, due to structural barriers, particularly access to healthcare. In this study, we used social media to recruit black, Hispanic, and white HIV-uninfected 18- to 24-year-old YMSM. Participants completed an online survey about their sexual behavior, healthcare access, and previous use of PrEP. Of the 2297 YMSM surveyed, only 3.4% had used PrEP. PrEP use was associated with higher levels of education, living alone, older age, higher levels of sexual activity, and greater healthcare access, specifically having healthcare insurance and a clinic or primary care provider (PCP) from whom they received care. Among PrEP nonusers, 65% met at least one of the US Centers for Disease Control and Prevention recommended indications for PrEP use, and of these, 59% had healthcare insurance and received care in a clinic and/or had a PCP. Multi-variable multi-nomial logistic regression modeling identified disparities in access to healthcare by age, race/ethnicity, education, and region. Specifically, older YMSM, blacks and Hispanics, those with fewer years of formal education, and residents of the southern and the western United States were more likely to lack healthcare access. These results demonstrate both potential opportunities and barriers to the scale-up of PrEP among YMSM.

Resilience to Discrimination and Rejection Among Young Sexual Minority Males and Transgender Females: A Qualitative Study on Coping With Minority Stress

Sexual minority and transgender status is associated with mental health disparities, which have been empirically and theoretically linked to stressors related to social stigma. Despite exposure to these unique stressors, many sexual minority and transgender individuals will not experience mental health disorders in their lifetime. Little is known about the specific processes that sexual minority and transgender youth use to maintain their wellbeing in the presence of discrimination and rejection. Semistructured interviews were conducted with 10 sexual minority males and transgender females aged 18-22 years, who currently met criteria for an operationalized definition of resilience to depression and anxiety. Data were analyzed qualitatively, yielding information related to a wide variety of problem-solving, support-seeking, and accommodative coping strategies employed by youth in the face of social stigma. Results are discussed in light of their clinical implications.

A novel Online-to-Offline (O2O) model for pre-exposure prophylaxis and HIV testing scale up

Introduction: PrEP awareness and uptake among men who have sex with men (MSM) and transgender women (TG) in Thailand remains low. Finding ways to increase HIV testing and PrEP uptake among high-risk groups is a critical priority. This study evaluates the effect of a novel Adam’s Love Online-to-Offline (O2O) model on PrEP and HIV testing uptake among Thai MSM and TG and identifies factors associated with PrEP uptake.

Methods: The O2O model was piloted by Adam’s Love (www.adamslove.org) HIV educational and counselling website. MSM and TG reached online by PrEP promotions and interested in free PrEP and/or HIV testing services contacted Adam’s Love online staff, received real-time PrEP eCounseling, and completed online bookings for receiving services at one of the four sites in Bangkok based on their preference. Auto-generated site- and service-specific e-tickets and Quick Response (QR) codes were sent to their mobile devices enabling monitoring and check-in by offline site staff. Service uptake and participant’s socio-demographic and risk behaviour characteristics were analyzed. Factors associated with PrEP uptake were assessed using multiple logistic regression.

Results: Between January 10th and April 11th, 2016, Adam’s Love reached 272,568 people online via the PrEP O2O promotions. 425 MSM and TG received eCounseling and e-tickets. There were 325 (76.5%) MSM and TG who checked-in at clinics and received HIV testing. Nine (2.8%) were diagnosed with HIV infection. Median (IQR) time between receiving the e-ticket and checking-in was 3 (0–7) days. Of 316 HIV-negative MSM and TG, 168 (53.2%) started PrEP. In a multivariate model, higher education (OR 2.30, 95%CI 1.14–4.66; p = 0.02), seeking sex partners online (OR 2.05, 95%CI 1.19–3.54; p = 0.009), being aware of sexual partners’ HIV status (OR 2.37, 95%CI 1.29–4.35; p = 0.008), ever previously using post-exposure prophylaxis (PEP) (OR 2.46, 95%CI 1.19–5.09; p = 0.01), and enrolment at Adam’s Love clinic compared to the other three sites (OR 3.79, 95%CI 2.06–6.95; p < 0.001) were independently associated with PrEP uptake.

Conclusions: Adam’s Love O2O model is highly effective in linking online at-risk MSM and TG to PrEP and HIV testing services, and has high potential to be replicated and scaled up in other settings with high Internet penetration among key populations.

Willingness to use pre-exposure prophylaxis for HIV prevention among men who have sex with men in Malaysia: Findings from an online survey

Objective

We examined willingness to use pre-exposure prophylaxis (PrEP) for HIV prevention among men who have sex with men (MSM) in Malaysia.

Methods

An online survey of 990 MSM was conducted between March and April 2016. Eligibility criteria included being biological male, Malaysian citizen, 18 years of age or above, identifying as MSM, and being HIV negative or unknown status. Participants’ demographics, sexual and drug use behaviors, attitudes towards PrEP, and preferences regarding future access to PrEP were collected. Bivariate analysis and logistic regression were performed to determine factors associated with willingness to use PrEP.

Results

Fewer than half of participants (44%) knew about PrEP before completing the survey. Overall, 39% of the sample were willing to take PrEP. Multivariate logistic regression indicated that Malay men (AOR: 1.73, 95% CI:1.12, 2.70), having 2 or more male anal sex partners in the past 6 months (AOR: 1.98, 95% CI: 1.29, 3.05), previous knowledge of PrEP (AOR: 1.40, 95%CI: 1.06, 1.86), lack of confidence in practising safer sex (AOR: 1.36, 95% CI: 1.02, 1.81), and having ever paid for sex with a male partner (AOR: 1.39, 95% CI: 1.01, 1.91) were independently associated with greater willingness to use PrEP, while men who identified as heterosexual were less willing to use PrEP (AOR, 0.36, 95% CI: 0.13, 0.97). Majority of participants preferred to access PrEP at affordable cost below 100 Malaysian Ringgit (USD25) per month from community based organisations followed by private or government hospitals.

Conclusions

Overall, MSM in Malaysia reported a relatively low level of willingness to use PrEP, although willingness was higher among those previously aware of PrEP. There is a need to provide PrEP at affordable cost, increase demand and awareness of PrEP, and to provide access to this preventative medication via diverse, integrated and tailored sexual health services.

Barriers to Access and Adoption of Pre-Exposure Prophylaxis for the Prevention of HIV Among Men Who Have Sex With Men (MSM) in a Relatively Rural State

Biomedical intervention approaches, including antiretroviral pre-exposure prophylaxis (PrEP), have been demonstrated to reduce HIV incidence among several at-risk populations and to be cost effective. However, there is limited understanding of PrEP access and uptake among men who have sex with men (MSM) residing in relatively rural states. Twenty semistructured interviews were conducted (August-November 2016) to assess opinions of and perceived barriers to accessing and adopting PrEP among MSM residing in Oklahoma. Participants perceived substantial barriers to accessing PrEP including a stigmatizing environment and less access to quality, LGBT-sensitive medical care. Overall, geographic isolation limits access to health providers and resources that support sexual health for Oklahoma MSM. Addressing stigma situated across ecological levels in an effort to increase adoption of PrEP by MSM residing in rural states remains necessary. Without this, social determinants may continue to negatively influence PrEP adoption and sexual health outcomes.

HIV Prevention Fatigue and HIV Treatment Optimism Among Young Men Who Have Sex With Men

HIV prevention fatigue (the sense that prevention messages are tiresome) and being overly optimistic about HIV treatments are hypothesized to increase HIV risk behavior. Little research has examined these constructs and their correlates among young men who have sex with men (YMSM), who are at high risk for HIV. YMSM (N = 352; M_age = 20; 50% Black) completed measures of prevention fatigue, treatment optimism, HIV risk behaviors, and HIV-related knowledge and attitudes during a longitudinal study. Overall, YMSM reported low levels of HIV prevention fatigue and treatment optimism. Path analysis (n = 307) indicated that greater prevention fatigue and treatment optimism predicted higher rates of condomless sex, but condomless sex did not predict later increases in prevention fatigue or treatment optimism. Results are inconsistent with the hypothesis of high prevention fatigue and treatment optimism among YMSM and point to potential causal relationships among these variables and condomless sex.

Preferences for Long-Acting Pre-exposure Prophylaxis (PrEP), Daily Oral PrEP, or Condoms for HIV Prevention Among U.S. Men Who Have Sex with Men

HIV prevention method preferences were evaluated among 512 U.S. men who have sex with men (MSM; median age: 22 years). Approximately 90 % consistently preferred one option across pairwise comparisons of condoms, daily oral pre-exposure prophylaxis (PrEP), and long-acting PrEP delivered via either an injectable or one of two types of PrEP implants differing in visibility. Condoms were most frequently preferred (33.8 %), followed by non-visible implants (21.5 %), and oral PrEP (17.0 %); HIV risk was reported by more choosing implants. In a follow-up question comparing the four PrEP options only, daily oral pills and non-visible implants were most frequently preferred (35.5 and 34.3 %, respectively), followed by injections (25.2 %) and visible implants (4.3 %). An inductive, open-coding approach determined that convenience, duration of protection, and privacy were the most commonly cited reasons for a PrEP method choice, and associated with self-report of HIV risk. Tailoring PrEP product development to privacy and other concerns important to those at highest HIV risk may improve HIV prevention.

Exploring Patterns of Awareness and Use of HIV Pre-Exposure Prophylaxis Among Young Men Who Have Sex with Men

Pre-exposure prophylaxis (PrEP) has shown promise as a safe and effective HIV prevention strategy, but there is limited research on awareness and use among young men who have sex with men (YMSM). Using baseline data from the "Keep It Up! 2.0" randomized control trial, we examined differences in PrEP awareness and use among racially diverse YMSM (N = 759; mean age = 24.2 years). Participants were recruited from study sites in Atlanta, Chicago, and New York City, as well as through national advertising on social media applications. While 67.5 % of participants reported awareness of PrEP, 8.7 % indicated using the medication. Awareness, but not use, varied by demographic variables. PrEP-users had twice as many condomless anal sex partners (ERR = 2.05) and more condomless anal sex acts (ERR = 1.60) than non-users. Future research should aim to improve PrEP awareness and uptake among YMSM and address condom use.

Prospective Effects of a Syndemic on HIV and STI Incidence and Risk Behaviors in a Cohort of Young Men Who Have Sex with Men

Young men who have sex with men continue to be highly affected by HIV. To improve understanding of the role that multiple co-occurring health issues (i.e., syndemics) play in HIV acquisition, sophisticated modeling methods are needed. The purpose of this study was to use structural equation modeling to understand the structure of the syndemic and to test its longitudinal association with condomless anal sex. Data are from a longitudinal study of 450 YMSM. A primary syndemic component comprised of substance use, violence, and internalizing mental health factors significantly predicted the number of condomless anal sex partners in the full sample. Analyses exploring associations by race/ethnicity found a significant association among White YMSM, but not among Black or Latino YMSM. Higher-order factor modeling suggests these psychosocial factors form a syndemic in all racial/ethnic groups, but the syndemic, as conceptualized here, may be less relevant to racial/ethnic minority YMSM.

Management of a Concealable Stigmatized Identity: A Qualitative Study of Concealment, Disclosure, and Role Flexing Among Young, Resilient Sexual and Gender Minority Individuals

Disclosure of a sexual or gender minority status has been associated with both positive and negative effects on wellbeing. Few studies have explored the disclosure and concealment process in young people. Interviews were conducted with 10 sexual and/or gender minority individuals, aged 18-22 years, of male birth sex. Data were analyzed qualitatively, yielding determinants and effects of disclosure and concealment. Determinants of disclosure included holding positive attitudes about one's identity and an implicit devaluation of acceptance by society. Coming out was shown to have both positive and negative effects on communication and social support and was associated with both increases and decreases in experiences of stigma. Determinants of concealment included lack of comfort with one's identity and various motivations to avoid discrimination. Concealment was also related to hypervigilance and unique strategies of accessing social support. Results are discussed in light of their clinical implications.
