Predictors of HIV-related risk perception and PrEP acceptability among young adult female family planning patients

Preference for and Efficacy of a PrEP Decision Aid for Women with Substance Use Disorders

BACKGROUND

Women with substance use disorders (SUDs) are a key population for HIV prevention with pre-exposure prophylaxis (PrEP), though uptake is limited by awareness of PrEP, misestimation of personal HIV risk, and minimally integrated HIV prevention and addiction treatment services. Patient-centered decision aids (DA) could address these barriers to PrEP, but no extant DA for PrEP has been published, including for women with SUDs.

METHODS

We developed a patient-centered PrEP DA for women in addiction treatment. In a pilot randomized preference trial, we compared the DA to enhanced standard of care (eSOC) providing standardized information. The primary outcome was opting to receive more information through the DA; we also assessed the impact of the DA on PrEP decisional preference and PrEP uptake over 12 months.

RESULTS

A total of 164 enrolled participants (DA: 83; eSOC: 81) were similar in terms of HIV risk and demographics, which are representative of women in addiction treatment programs nationally, and most (92%) had opioid use disorder. Half of participants were PrEP eligible, though 37% underestimated their personal HIV risk. Independent correlates of selecting the PrEP DA relative to eSOC included higher alcohol use severity (aOR 4.13, 95% CI 1.05-16.28, p=0.04) and perception of high risk for HIV (aOR 2.95, 95% CI 1.19-7.35, p=0.02). For those selecting the DA, interest in PrEP increased significantly from 25% to 89%. DA participants were also significantly more likely than eSOC participants to see a provider for PrEP during follow-up (15.7% vs 6.2%; p=0.05).

CONCLUSION

Half of the women selected to use the DA, and those who did significantly increased their engagement in the HIV prevention cascade through increased interest in and initiation of PrEP. Future iterations should accelerate the HIV prevention cascade for women with SUDs by integrating PrEP decision aids into existing addiction treatment services and actively linking women to PrEP.

The PEARL study: a prospective two-group pilot PrEP promotion intervention for cisgender female sex workers living in Baltimore, MD, U.S

HIV remains elevated among female sex workers (FSW) globally, with a number of structural (e.g., poverty, access to care) factors driving these persistently high rates. Pre-exposure prophylaxis (PrEP), a user-controlled prevention method, is a promising means of empowering vulnerable populations to protect themselves and enhance agency. Yet there is a dearth of PrEP research and interventions targeting cisgender women in the United States, and even fewer aimed to reach FSW. We developed and implemented a multifaceted PrEP pilot intervention, the Promoting Empowerment And Risk Reduction (PEARL) study, to meet this gap. This paper describes the development process and nature of a community-informed intervention for tenofovir/emticitrabine (TDF/FTC) pre-exposure prophylaxis engagement among street-based cisgender FSW in Baltimore, Maryland, U.S. In the course of the study's implementation, structural, programmatic, and medical barriers have already posed significant barriers to full engagement. PEARL implemented a number of strategies in an effort to counter barriers and facilitate increased success of PrEP uptake and maintenance. The study will provide critical insights into the nature of intervention components that could help FSW to initiate PrEP and reduce PrEP care cascade gaps.

PrEP Implementation Behaviors of Community-Based HIV Testing Staff: A Mixed-Methods Approach Using Latent Class Analysis

BACKGROUND

Pre-exposure Prophylaxis (PrEP) is an important option for HIV prevention, but the approach has reached a limited number of people at risk of HIV infection.

METHODS

A mixed-methods concurrent triangulation design was used to investigate unobserved subgroups of staff who provide community-based, publicly funded HIV testing in Florida (USA). PrEP implementation groups, or classes, were determined using latent class analysis. Generalized linear mixed models were used to estimate PrEP implementation as a function of staff characteristics. In-depth interviews based on the Consolidated Framework for Implementation Research were analyzed thematically.

RESULTS

Based on fit statistics and theoretical relevance, a 3-class latent class analysis was selected. Class 1 ("Universal") staff were highly likely to talk about PrEP with their clients, regardless of client eligibility. Class 2 ("Eligibility dependent") staff were most likely to discuss PrEP if they believed their client was eligible. Class 3 ("Limited") staff sometimes spoke to clients about PrEP, but not systematically. In multivariate analyses, only race and sexual orientation remained significant predictors of the PrEP implementation group. Staff who identified as a racial or sexual minority were less likely to be in the Limited group than their heterosexual or white counterparts. Age, gender, ever having taken PrEP, and HIV status did not impact the odds of being in a specific PrEP implementation group.

CONCLUSIONS

A subset of HIV testing staff differentially discuss PrEP based on perceived client eligibility; others inconsistently talk to clients about PrEP. Targeted training based on PrEP implementation groups may be beneficial.

HIV-Related Mistrust (or HIV Conspiracy Theories) and Willingness to Use PrEP Among Black Women in the United States

Uptake of pre-exposure prophylaxis (PrEP) among Black women living in the US is suboptimal. We sought to determine the association between HIV-related medical mistrust (or belief in HIV conspiracy theories) and willingness to use PrEP among Black women. We analyzed data from the 2016 National Survey on HIV in the Black Community (NSHBC), a nationally representative cross-sectional survey. Among NSHBC participants, 522 were women and 347 (69.0%) reported HIV risk factors. Only 14.1% were aware that PrEP exists; 30.8% reported willingness to use PrEP. HIV-related medical mistrust was reported by 60.4% of women. In multivariable analysis, controlling for income, education, marital status and health care engagement, belief in conspiracy theories was significantly associated with higher willingness to use PrEP. The HIV-Related Medical Mistrust Scale item: "there is a cure for HIV, but the government is withholding it from the poor" was independently associated with higher PrEP willingness. This finding speaks to the need for an improved understanding of the role of HIV-related medical mistrust among Black women to improve uptake of biomedical HIV prevention.

Associations Among HIV Risk Perception, Sexual Health Efficacy, and Intent to Use PrEP Among Women: An Application of the Risk Perception Attitude Framework

HIV risk perception is a known determinant of HIV prevention behaviors among vulnerable populations. Lesser known is the combined influence of risk perception and efficacy beliefs on PrEP use. We examined the associations between levels of risk perception and strength of efficacy beliefs on intent to use PrEP in a sample of adult Black and Latina women. Guided by the risk perception attitudes (RPA) framework, we used cluster analysis to identify four interpretable groups. We ran analysis of covariance models to determine the relationship between membership in the RPA framework groups and intention to use PrEP. Among the 908 women, the mean age was 29.9 years and participants were Latina (69.4%) and Black (25.6%). Results of the analysis show that women with low perception of HIV risk and strong efficacy beliefs had significantly less intent to use PrEP than women with high risk perception and weak efficacy beliefs.

Pre-Exposure Prophylaxis Integration Into Family Planning Services at Title X Clinics in the Southeastern United States: Protocol for a Mixed Methods Hybrid Type I Effectiveness Implementation Study (Phase 2 ATN 155)

Background

Adolescent and young adult women (AYAW), particularly racial and ethnic minorities, in the Southern United States are disproportionately affected by HIV. Pre-exposure prophylaxis (PrEP) is an effective, scalable, individual-controlled HIV prevention strategy that is grossly underutilized among women of all ages and requires innovative delivery approaches to optimize its benefit. Anchoring PrEP delivery to family planning (FP) services that AYAW already trust, access routinely, and deem useful for their sexual health may offer an ideal opportunity to reach women at risk for HIV and to enhance their PrEP uptake and adherence. However, PrEP has not been widely integrated into FP services, including Title X–funded FP clinics that provide safety net sources of care for AYAW. To overcome potential implementation challenges for AYAW, Title X clinics in the Southern United States are uniquely positioned to be focal sites for conceptually informed and thoroughly evaluated PrEP implementation science studies.

Objective

The objective of this study is two-fold: to evaluate multilevel factors associated with the level of PrEP adoption and implementation (eg, PrEP screening, counseling, and prescription) within and across 3 FP clinics and to evaluate PrEP uptake, persistence, and adherence among female patients in these clinics over a 6-month follow-up period.

Methods

Phase 2 of Planning4PrEP (Adolescent Medicine Trials Network for HIV/AIDS Interventions 155) is a mixed methods hybrid type 1 effectiveness implementation study to be conducted in three clinics in Metro Atlanta, Georgia, United States. Guided by the Exploration, Preparation, Implementation, and Sustainment framework, this study will prepare clinics for PrEP integration via clinic-wide trainings and technical assistance and will develop clinic-specific PrEP implementation plans. We will monitor and evaluate PrEP implementation as well as female patient PrEP uptake, persistence, and adherence over a 6-month follow-up period.

Results

Phase 2 of Planning4PrEP research activities began in February 2018 and are ongoing. Qualitative data analysis is scheduled to begin in Fall 2020.

Conclusions

This study seeks to evaluate factors associated with the level of PrEP adoption and implementation (eg, PrEP screening, counseling, and prescription) within and across 3 FP clinics following training and implementation planning and to evaluate PrEP uptake, persistence, and adherence among female patients over a 6-month follow-up period. This will guide future strategies to support PrEP integration in Title X–funded clinics across the Southern United States.

Pre-exposure Prophylaxis Use Among Men Who Have Sex with Men Experiencing Partner Violence

Intimate partner violence (IPV) significantly increases HIV risk among MSM. Pre-exposure prophylaxis (PrEP) may provide MSM experiencing IPV an option for self-protection from HIV without requiring condom negotiation or compromising safety. This study examined relationships among various forms of IPV (physical, emotional, monitoring, controlling, and forced sex) and PrEP use among 863 MSM participating in a cross-sectional, internet-based survey. Participants reported IPV rates during the prior 6 months that were consistent with prior research (physical violence, 23.3%; emotional violence, 36.3%; monitoring, 45.1%; controlling, 25.3%; forced sex, 20.0%). Forced sex and emotional IPV were negatively associated with PrEP use in our sample; in contrast, controlling was positively associated with PrEP use. We suggest clinical IPV screenings among MSM seeking PrEP, as well as PrEP-focused interventions that explicitly address IPV.

The Influence of Relationship Dynamics and Sexual Agreements on Perceived Partner Support and Benefit of PrEP Use Among Same-Sex Male Couples in the U.S

Use of Pre-exposure prophylaxis (PrEP) for HIV prevention by men who have sex with men (MSM) may be impacted by relationship dynamics. We assessed perceived partner support of PrEP use and benefit of PrEP by relationship characteristics among male couples. Baseline data from a randomized control trial of video-based HIV counseling and testing among male couples in the U.S. were used in adjusted multilevel regression models to assess individual and dyadic characteristics. Among 659 participants, 73.3% thought their partner would be supportive of their PrEP use; 26.7% reported their partner would not support PrEP use, which was significantly associated with intimate partner violence (IPV) (p = 0.008). Most (57.7%) did not believe PrEP would be beneficial to them or their partner. Couples with a sexual agreement allowing outside partners were significantly associated with higher perceived support of partners for PrEP (p < 0.001) and benefit of PrEP use (p < 0.001). Perceived partner support of PrEP was high but perceived benefit of PrEP was low, both shaped by relationship dynamics that highlight the need for tailored dyadic interventions. The association between perceived PrEP support and IPV points to the need to integrate relationship contexts in HIV prevention programs.

The Impact of HIV Pre-Exposure Prophylaxis (PrEP) Counseling on PrEP Knowledge and Attitudes Among Women Seeking Family Planning Care

Background: Adult women account for >19% of all new HIV diagnoses in the United States, but receive only 7%-8% of new prescriptions for HIV pre-exposure prophylaxis (PrEP), and report low awareness of PrEP even within communities with high risk of HIV transmission. Family planning (FP) programs are a promising, underutilized setting for the provision of PrEP counseling to women, especially the 40% of women FP clients who receive no other form of health care. This study tested the feasibility of integrating routine PrEP counseling in a high-volume FP clinic with no previous PrEP experience. Materials and Methods: Trained FP counselors at a FP clinic in Philadelphia surveyed women about knowledge and attitudes related to PrEP, then provided a brief PrEP counseling intervention. After counseling, knowledge and attitudes were reassessed. In response to counselor requests, we developed the Women's PrEP Counseling Checklist (WPCC) tool to structure and standardize each counseling session. We then compared baseline and postintervention data among participants overall and in two cohorts: those receiving unguided counseling (initial design) and those receiving WPCC-guided counseling (enhanced design). Results: Both cohorts displayed significant (p < 0.0001) gains in PrEP knowledge and acceptability after counseling. Participants receiving WPCC-guided counseling reported higher knowledge scores postintervention (p = 0.031) and greater gains in PrEP acceptability (p = 0.000) than their peers receiving unguided counseling. Conclusions: Introducing PrEP counseling into routine FP care is feasible, and effectively improves knowledge and attitudes about PrEP within a large population of women, broadening access to PrEP on individual and population levels. The WPCC tool both enhances the impact of counseling on patients and reduces the work burden on providers.

Integrating HIV Pre-Exposure Prophylaxis into Family Planning Care: A RE-AIM Framework Evaluation

We aimed to systematically evaluate the feasibility of integrating HIV prevention services, including pre-exposure prophylaxis (PrEP), into a family planning setting in a high-prevalence community. We used the RE-AIM Framework (Reach, Efficacy, Adoption, Implementation, Maintenance) to evaluate the integration of HIV prevention services into a family planning clinic over 6 months. Before the integration, PrEP was not offered. We implemented a staff training program on HIV PrEP. We determined the proportion of women presenting to the clinic who were screened, eligible for, and initiated PrEP through chart review. We assessed staff comfort with PrEP pre- and post-integration. We compared planned and actual implementation, interviewed staff to determine barriers and facilitators, and tracked systems adaptations. We assessed maintenance of PrEP after the study concluded. There were 640 clinical encounters for 515 patients; the rate of HIV counseling and PrEP screening was 50%. The rate was 10% in month 1 and peaked to 65% in month 3. Nearly all screened patients were eligible for PrEP (98.4%) and 15 patients (6%) initiated PrEP. Staff knowledge and comfort discussing PrEP improved after education. Facilitators included partnering with local experts, continuing education, clinical tools for providers, and patient education materials. Barriers included competing priorities during clinical encounters, limited woman-centered patient education materials, and insurance-related barriers. Embedding HIV prevention services in the family planning setting was feasible in this pilot. The proportion of women screened for PrEP rapidly increased. In this high HIV prevalence community, nearly all screened women were eligible and 6% initiated PrEP.

Health Care Provider Perspectives on Pre-exposure Prophylaxis: A Qualitative Study

Although pre-exposure prophylaxis (PrEP) requires a prescription from a health care provider, we lack unanimity in guidelines for the identification of the ideal provider type to prescribe PrEP. The purpose of our study was to understand clinician perspectives on provider categories to determine who is best suited to prescribe this medication to HIV-uninfected patients. We conducted 28 in-depth interviews between September 2017 and January 2018 with current prescribers of PrEP. Qualitative findings indicated that providers were split on recommended PrEP prescriber type. Five themes emerged that centered on the explicit identification of the issue of opportunity for providers to educate their patients on PrEP and offer this medication to at-risk populations. To effectively maximize presentation for care and subsequently amplify uptake of PrEP, growing the base of providers who offer PrEP to eligible patients can provide a meaningful public health impact on reducing HIV incidence.

Racial and ethnic differences in women's HIV risk and attitudes towards pre-exposure prophylaxis (PrEP) in the context of the substance use, violence, and depression syndemic

Women with syndemic conditions, i.e., two or more co-occurring epidemics, are at elevated risk for HIV acquisition and are therefore prime candidates for pre-exposure prophylaxis (PrEP). However, PrEP uptake remains low among women, especially among Black and Hispanic women. This study examined associations of syndemic conditions with PrEP attitudes and HIV risk among women, and the moderating effect of race and ethnicity. In 2017, 271 non-Hispanic Black, non-Hispanic White, and Hispanic, PrEP-eligible women engaged in care at Planned Parenthood in the northeastern region of the U.S. completed an online survey. Participants reported syndemic conditions (i.e., intimate partner violence, depression, substance use), PrEP attitudes (e.g., PrEP interest), HIV sexual risk (e.g., multiple male sexual partners), and sociodemographics. Structural equation modeling was used to examine the effects of syndemic conditions on PrEP attitudes and HIV risk, and the moderating effect of race and ethnicity. Women with more syndemic conditions had a higher odds of reporting multiple male sexual partners. Syndemic conditions were positively associated with PrEP attitudes for Hispanic women than non-Hispanic Black and White women. Women with syndemic conditions, particularly Hispanic women, may be receptive to interventions promoting PrEP.

Intimate Partner Violence and Pre-exposure Prophylaxis (PrEP): A Rapid Review of Current Evidence for Women's HIV Prevention

Pre-exposure prophylaxis (PrEP) is a valued component of HIV prevention and increasing attention is focusing on women's PrEP use. Common HIV prevention options (e.g., condoms) remain underused and fail to consider the context of intimate partner violence (IPV). PrEP presents an opportunity to expand viable options for women. A systematic rapid review using key word searches of PubMed and proceedings from six national and international conferences related to HIV, women's health, or interpersonal violence identified nine studies which met set inclusion criteria. Studies were coded using a structured abstraction form and summarized according to relevant themes. IPV was found to have implications on women's interest and willingness to use PrEP, partner interference or interruptions in PrEP use, and adherence. Findings indicate a dearth of research on women's PrEP use and IPV and highlight the urgency for research, public heath practice, and policy attention around the HIV risk context and needs of women who experience IPV.

The PrEP Care Continuum Among Cisgender Women Who Sell Sex and/or Use Drugs Globally: A Systematic Review

HIV prevalence among cisgender female sex workers (FSW) and/or women who use drugs (WWUD) is substantially higher compared to similarly aged women. Consistent with PRISMA guidelines, we conducted the first systematic review on the pre-exposure prophylaxis (PrEP) continuum among FSW and/or WWUD, searching PubMed, Embase, CINAHL, PsycInfo, and Sociological Abstracts. Eligibility criteria included: reporting a PrEP related result among FSW and/or WWUD aged 18 + ; peer-reviewed; and published in English between 2012 and 2018. Our search identified 1365 studies; 26 met eligibility requirements, across the following groups: FSW (n = 14), WWUD (n = 9) and FSW-WWUD (n = 3). Studies report on at least one PrEP outcome: awareness (n = 12), acceptability (n = 16), uptake (n = 4), and adherence (n = 8). Specific barriers span individual and structural levels and include challenges to daily adherence, cost, and stigma. Combining health services and long-acting PrEP formulas may facilitate better PrEP uptake and adherence. The limited number of studies indicates a need for more research.

Interest in HIV pre-exposure prophylaxis (PrEP) among adolescents and their caregivers in Malawi

Over a third of new HIV infections occur in adolescents aged 10-19 globally. Pre-exposure prophylaxis (PrEP) could be a powerful tool for prevention. Understanding more about the drivers of PrEP interest could inform implementation strategies among this age group. Moreover, family dynamics may play a uniquely critical role for this younger age group, thus it is important to gauge whether caregivers would support their children's use of PrEP. We surveyed 2,089 adolescents (aged 10-16) and their caregivers in Malawi during 2017-2018. Data were collected on PrEP interest, factors that may facilitate PrEP use, and preferences for PrEP modality. We used multivariate logistic regression to estimate the association between the above characteristics and PrEP interest. We find that young adolescents are engaging in behaviors that would put them at substantial risk of acquiring HIV, would likely benefit from PrEP, are largely (82%) interested in using such, would prefer to get an injection over taking a daily pill, and are considerably discouraged by the prospect of side effects. Endorsement by caregivers was even greater (87%). Our findings demonstrate initial support for adolescent PrEP, and suggest parents may be a surprising advocate.

Contraception as a Potential Gateway to Pre-Exposure Prophylaxis: US Women's Pre-Exposure Prophylaxis Modality Preferences Align with Their Birth Control Practices

Addressing women's low uptake of HIV pre-exposure prophylaxis (PrEP) requires improved understanding of their product preferences. Such preferences should be contextualized according to other aspects of their reproductive health, including their contraception practices. We investigated women's preferences across 10 PrEP modalities currently available or under study and examined associations between PrEP modality preferences and contraception practices. Heterosexually active women recently engaged in care at Connecticut Planned Parenthood centers (n = 563) completed an online survey. Participants were presented with images and descriptions of 10 PrEP modalities and asked to indicate their preference and specify their reasoning in an open-response format. Participants also reported prior and current use of 16 contraception modalities along with relationship, sexual health, and sociodemographic characteristics. The sample included women ages 18-45 (45.3% 25 or younger) who were predominantly non-Hispanic black (35.7%) or white (33.7%). All PrEP modalities presented were preferred by at least some women, with daily pills (24.9%), injections (24.3%), and invisible implants (14.9%) preferred most commonly. Across all modalities, associated reasoning often centered around ease of use and comfort. Coincidence with contraception modality was the third-most common reason underlying women's preferences. Women currently using the analogous contraception modality versus never having used it had higher odds of preferring PrEP daily pills [adjusted odds ratio (AOR) = 2.03], injections (AOR = 8.45), invisible implants (AOR = 11.63), and vaginal rings (AOR = 8.66). Diversification of available PrEP modalities and prioritization of those coinciding with popular contraception practices-especially daily pills, injections, and implants-could optimize PrEP acceptability, encourage PrEP uptake, and ultimately reduce HIV incidence among women.

Brief Report: Impact of PrEP Training for Family Planning Providers on HIV Prevention Counseling and Patient Interest in PrEP in Atlanta, Georgia

BACKGROUND

Safety net family planning (FP) clinics provide vital care for women in high HIV-burden areas and may be ideal pre-exposure prophylaxis (PrEP) delivery sites. Yet, many FP providers lack knowledge about PrEP.

SETTING

Four safety net FP clinics in Atlanta, Georgia.

METHODS

We provided a 1.5-hour PrEP informational training for 28 providers working in these sites. To assess the training's impact on PrEP counseling, we enrolled 500 female patients after training (47% ≤ 28 years; 69% black; 12% Hispanic) and determined their PrEP indication based on CDC guidelines. We conducted a postvisit survey to assess provider counseling and patients' interest in PrEP and acceptance of off-site PrEP referral.

RESULTS

From pre-training to post-training, provider PrEP knowledge and confidence to identify women who may benefit from PrEP significantly increased. Only 19% of women knew about PrEP before the visit. Among 376 sexually active women, 29% had risk consistent with PrEP indication. Among PrEP-indicated women, 66% reported the provider discussed PrEP, 29% were interested in taking PrEP, but only 18% accepted off-site PrEP referral. Most (76%) were more willing to take PrEP if provided by the FP clinic.

CONCLUSIONS

After a brief PrEP training, most women with HIV-risk indicators received PrEP counseling during their visits. Once counseled, women expressed interest if it were offered at the FP clinic rather than through off-site referral. Findings highlight the potential impact that PrEP capacity building within safety net FP clinics in high HIV-burden areas may have on PrEP scale-up for women.

Persistence on HIV preexposure prophylaxis medication over a 2-year period among a national sample of 7148 PrEP users, United States, 2015 to 2017

Introduction

Persistence on preexposure prophylaxis for HIV prevention (PrEP) medication has rarely been reported for periods greater than one year, or in real‐world settings. This study used pharmacy fill records for PrEP users from a national chain pharmacy to describe persistence on PrEP medication over a two‐year period, and to explore correlates with PrEP medication persistence in a real‐world setting.

Methods

We analysed de‐identified pharmacy fill records of 7148 eligible individuals who initiated PrEP in 2015 at a national chain pharmacy. A standard algorithm was employed to identify TDF‐FTC use for PrEP indication. We considered three time periods for persistence, defined as maintaining refills in PrEP care: year 1 (zero to twelve months), year 2 (thirteen to twenty‐four months) and initiation to year 2 (zero to twenty‐four months). Individuals with 16 or more days of TDF‐FTC PrEP dispensed in a 1‐month period for at least three‐quarters of a given time period (e.g. nine of twelve months or eighteen of twenty‐four months) were classified as persistent on PrEP medication for the period.

Results

Persistence was 56% in year 1, 63% in year 2 and 41% from initiation to year 2. Individuals aged 18 to 24 had the lowest persistence, with 29% from initiation to year 2. Men had higher persistence than women, with 42% compared to 20% persistent from initiation to year 2. Individuals with commercial insurance and individuals who utilized a community‐based specialty pharmacy from the national chain also had higher persistence. Male gender, age >18 to 24 years, average monthly copay of $20 or less, commercial insurance, and utilization of a community‐based specialty pharmacy were positively associated in adjusted models with persistence in year 1 and from initiation to year 2; the same correlates, with the exception of utilization of a community‐based specialty pharmacy, were associated with higher persistence in year 2.

Conclusions

We found substantial non‐persistence on PrEP medication in both year 1 and year 2. Across the entire 2‐year period, only two out of every five users persisted on PrEP. Demographic, financial and pharmacy factors were associated with persistence. Further research is needed to explore how social, structural or individual factors may undermine or enhance persistence on PrEP, and to develop interventions to assist persistence on PrEP.

Intimate Partner Violence Influences Women's Engagement in the Early Stages of the HIV Pre-exposure Prophylaxis (PrEP) Care Continuum: Using Doubly Robust Estimation

Intimate partner violence (IPV) is associated with pre-exposure prophylaxis (PrEP) acceptability among US women, but whether IPV influences other steps along the PrEP care continuum remains unclear. This study estimated the causal effects of IPV on the early stages of the PrEP care continuum using doubly robust (DR) estimation (statistical method allowing causal inference in non-randomized studies). Data were collected (2017-2018) from a cohort study of 124 US women without and 94 women with IPV experiences in the past 6 months (N = 218). Of the 218 women, 12.4% were worried about getting HIV, 22.9% knew of PrEP, 32.1% intended to use PrEP, and 40.4% preferred an "invisible" PrEP modality. IPV predicts HIV-related worry (DR estimate = 0.139, SE = 0.049, p = 0.004). IPV causes women to be more concerned about contracting HIV. Women experiencing IPV are worried about HIV, but this population may need trauma-informed approaches to help facilitate their PrEP interest and intentions.

Key barriers and enablers associated with uptake and continuation of oral pre-exposure prophylaxis (PrEP) in the public sector in Zimbabwe: Qualitative perspectives of general population clients at high risk for HIV

Background

Understanding the perspectives and preferences of clients eligible for pre-exposure prophylaxis (PrEP) is essential to designing programs that meet clients’ needs. To date, most PrEP programs in limited-resource settings have been implemented by partner organizations for specific target populations, but the government of Zimbabwe aims to make PrEP available to the broader population at substantial risk in public sector clinics. However, there is limited information on general population perspectives about PrEP in Zimbabwe.

Methods

A qualitative study was conducted to explore clients’ motivation to take or decline PrEP and continue or discontinue PrEP. Through a PrEP pilot in one urban family planning clinic and one rural youth center in Zimbabwe, 150 HIV-negative clients screened as being at high risk of HIV and were offered PrEP between January and June 2018. Sixty semi-structured interviews were conducted with clients who agreed to follow-up (including 5 decliners, all from the rural youth center, and 55 accepters, with 42 from the rural youth center and 13 from the urban family planning clinic). Interviews were conducted after either the first or second PrEP follow-up appointment or after the client declined PrEP. Interviews were audio recorded, de-identified, transcribed, and coded thematically.

Results

PrEP uptake was driven by risk perception for HIV, and in many cases, that risk was introduced by the unsafe behavior or HIV-positive status of a partner. Among sero-discordant couples (SDCs), the desire to safely conceive a child was also cited as a factor in taking PrEP. Clients who opted for PrEP preferred it to other forms of HIV prevention. SDCs reported decreased condom use after PrEP initiation and in some cases were using PrEP while trying to conceive a child. After initiating PrEP, clients had more confidence in their sexual relationships and less stress associated with negotiating condom use. Family and partner support was critical to starting and continuing PrEP, but some clients stopped PrEP or missed appointments due to side effects or logistical challenges such as transportation.

Conclusions

Results of this study can be used to provide operational guidance for national public sector roll-out of PrEP as part of combination HIV prevention in Zimbabwe. Based on feedback and experiences of clients, the training materials for health workers can be refined to ensure that health workers are prepared to counsel clients on the decision to start and/or continue PrEP and answer common client questions. Program advertisements should also be targeted with key messages that speak to client experiences.

Brief Report: PrEP Eligibility Among At-Risk Women in the Southern United States: Associated Factors, Awareness, and Acceptability

BACKGROUND

Among women in the United States, non-Latina black women in the South have disproportionately high rates of new HIV infections but low use of pre-exposure prophylaxis (PrEP). Effective strategies to identify factors associated with PrEP eligibility could facilitate improved screening, offering, and uptake of PrEP among US women at risk of HIV.

SETTING AND METHODS

We applied 2014 CDC criteria for PrEP use to at-risk HIV-negative women enrolled in the Southern US sites (Atlanta, Chapel Hill, Birmingham/Jackson, Miami) of the Women's Interagency HIV Study from 2014 to 2015 to estimate PrEP eligibility and assess PrEP knowledge and acceptability. Factors associated with PrEP eligibility were assessed using multivariable models.

RESULTS

Among 225 women, 72 (32%) were PrEP-eligible; the most common PrEP indicator was condomless sex. The majority of PrEP-eligible women (88%) reported willingness to consider PrEP. Only 24 (11%) PrEP-eligible women had previously heard of PrEP, and only 1 reported previous use. Education level less than high school [adjusted odds ratio (aOR) 2.56; 95% confidence interval (CI): 1.22 to 5.37], history of sexual violence (aOR 4.52; 95% CI: 1.52 to 17.76), and medium to high self-perception of HIV risk (aOR 6.76; 95% CI: 3.26 to 14.05) were significantly associated with PrEP eligibility in adjusted models.

CONCLUSIONS

Extremely low PrEP awareness and use despite a high proportion of eligibility and acceptability signify a critical need to enhance PrEP education and delivery for women in this region. Supplementing CDC eligibility criteria with questions about history of sexual violence and HIV risk self-assessment may enhance PrEP screening and uptake among US women.

Awareness and Intent to Use Pre-exposure Prophylaxis (PrEP) Among African American Women in a Family Planning Clinic

Due to the gap between cisgender women eligible for and those accessing pre-exposure prophylaxis (PrEP) for HIV prevention, it is critical to understand knowledge of and attitudes toward PrEP among HIV-vulnerable women. PrEP utilization is particularly low among African American women in the USA. Family planning clinics provide key access points to reach HIV-vulnerable African American women as well as to translate research findings into clinical practice. Our study aimed to (1) describe the awareness of and interest in PrEP among African American cisgender women attending a family planning clinic and (2) document the barriers and facilitators to PrEP uptake among these women. A cross-sectional survey was conducted with sexually active African American women of reproductive age attending a family planning clinic. Descriptive statistics were used to characterize the sample, and bivariate analysis was used to detect difference between categorical and outcome variables. In our survey (N = 109), over 80% of participants listed not knowing PrEP was available as the primary reason for not currently taking PrEP. Seventy percent reported they would probably or definitely like to take PrEP - demonstrating that barriers to uptake might stem from knowledge deficits rather than attitudes toward prevention. Study findings have the potential to inform strategies to increase awareness of PrEP as an HIV prevention option as well as to equip women with greater self-efficacy to access PrEP in family planning settings.

Intimate Partner Violence Experiences Among Men Living with HIV in Rural Appalachia

There has been limited study of the syndemic link between HIV and intimate partner violence (IPV) among rural populations in the United States. We utilized the Revised Conflict Tactics Scale-2 to examine the past year prevalence, type (psychological aggression, physical assault, and sexual assault), and the impact of IPV on HIV clinical outcomes among men living with HIV in rural Appalachia. Approximately 39% of participants experienced some type of IPV in the preceding year, with 67% of those individuals experiencing more than 1 type of IPV. Approximately 77% of participants endorsing IPV exposure experienced psychological aggression. Most participants exposed to psychological aggression (70%) and/or physical assault (57%) were both victims and perpetrators, and those experiencing sexual assault reported being exclusively victims (65%). There were no significant differences in clinical outcomes including viral load and CD4 count, which may be secondary to small sample size derived from a clinic population with a high rate of virologic suppression (94%). This study demonstrates the need to assess IPV exposure in men living with HIV and further highlights the intricacies of relationship violence in these individuals.

HIV Pre-Exposure Prophylaxis Stigma as a Multidimensional Barrier to Uptake Among Women Who Attend Planned Parenthood

BACKGROUND

Pre-exposure prophylaxis (PrEP) uptake has lagged among US women. PrEP stigma is a recognized barrier to uptake among men who have sex with men but remains largely unexplored among women. This study examined the pervasiveness of PrEP stigma among US women and its implications for uptake.

SETTING/METHODS

In a 2017 online survey of Planned Parenthood patients drawn from the 3 cities with the highest numbers of new HIV infections in Connecticut, 597 heterosexually active, HIV-negative, PrEP-inexperienced women reported background characteristics, 2 dimensions of anticipated PrEP stigma (PrEP-user stereotypes and PrEP disapproval by others), and 3 indicators of potential PrEP uptake (interest in learning more about PrEP, intention to use PrEP, and comfort discussing PrEP with a provider).

RESULTS

Participants commonly perceived PrEP-user stereotypes, with many believing that others would regard them as promiscuous (37%), HIV-positive (32%), bad (14%), or gay (11%) if they used PrEP. Thirty percent would feel ashamed to disclose PrEP use. Many participants expected disapproval by family (36%), sex partners (34%), and friends (25%). In adjusted analyses, perception of PrEP-user stereotypes was uniquely associated with less comfort discussing PrEP with a provider. Expected PrEP disapproval by others was uniquely associated with less PrEP interest, less intention to use PrEP, and less comfort discussing PrEP with a provider. Exploratory moderation analyses suggested that intention to use PrEP was greatest when participants anticipated low levels of both PrEP-user stereotypes and PrEP disapproval by others.

CONCLUSIONS

Findings highlight the need for positive messaging targeting potential PrEP users and their social networks to increase PrEP acceptance and uptake.

Psychometric properties of the European Portuguese version of the Perceived Risk of HIV Scale in the general population and HIV-uninfected partners from sero-different couples

Background

Perceived risk of HIV plays an important role in the adoption of protective behaviours and HIV testing. However, few studies have used multiple-item measures to assess this construct. The Perceived Risk of HIV Scale (PRHS) is an 8-item measure that assesses how people think and feel about their risk of HIV infection. This cross-sectional study aimed to assess the psychometric properties (reliability and validity) of the European Portuguese version of the PRHS, including the ability of this scale to discriminate between individuals from the general population and HIV-uninfected partners from sero-different couples on their perceived risk of HIV infection (known-groups validity).

Methods

This study included 917 individuals from the general population (sample 1) to assess the psychometric properties of the PRHS. To assess the known-groups validity, the sample comprised 445 participants from the general population who were in an intimate relationship (sub-set of sample 1) and 42 HIV-uninfected partners from sero-different couples (sample 2). All participants filled out a set of questionnaires, which included a self-reported questionnaire on sociodemographic information, sexual behaviours, HIV testing and the PRHS. Sample 1 also completed the HIV Knowledge Questionnaire – 18-item version.

Results

The original unidimensional structure was reproduced both in exploratory and confirmatory factor analyses, and the PRHS demonstrated good reliability (α = .78; composite reliability = .82). The differential item functioning analyses indicated that the items of the PRHS, in general, did not function differently for men and women or according to HIV testing. Significant associations with sexual risk behaviours and HIV testing provided evidence for criterion validity. The known-groups validity was supported.

Conclusions

The PRHS is a suitable scale in the evaluation of the perceived risk of HIV, and its psychometric characteristics validate its use in the Portuguese population. Furthermore, the present study suggests that interventions improving individuals’ HIV risk perceptions may be important since they were associated with different sexual behaviours and the likelihood of HIV testing.

Acceptability of a long-acting injectable HIV prevention product among US and African women: findings from a phase 2 clinical Trial (HPTN 076)

INTRODUCTION

High HIV incidence and low adherence to daily oral PrEP among women underscore the need for more acceptable and easier to use HIV prevention products. Global demand for injectable contraception suggests that new, long-acting, injectable formulations could meet this need. We examine acceptability of a long-acting injectable PrEP among HIV-uninfected women in Zimbabwe, South Africa and two United States phase 2 trial sites.

METHODS

Quantitative surveys were administered at the first, fourth and sixth injection visits. Focus group discussions (FGD) were conducted after the sixth injection visit. We compared the acceptability of injectable product attributes, prevention preferences and future interest in injectable PrEP by site and arm and ran longitudinal ordinal logistic regression models to identify determinants of future interest in injectable PrEP.

RESULTS

Between April 2015 and February 2017, the trial enrolled 136 (100 African, 36 US) women with a median age of 31 years. Most participants (>75%) rated injectable attributes as very acceptable. While few reported rash or other side effects, 56% to 67% reported injection pain, with nonsignificant differences over time and between arms. During FGDs, participants described initial fear of the injectable and variable experiences with pain. Most US and African participants preferred injectable PrEP to daily oral pills (56% to 96% vs. 4% to 25%). Future interest in using injectable PrEP was associated with acceptability of product attributes and was higher in African than US sites. In FGDs, participants described multiple reasons for trial participation, including a combination of monetary, health-related and altruistic motivations. While associated with future interest in use in univariate models, neither altruistic nor personal motivations remained significant in the multivariate model.

CONCLUSIONS

This study found that long-acting injectable PrEP is acceptable among African and US women experiencing product use. Acceptability of product attributes better predicted future interest in injectable use than experience of pain. This is reassuring as a single-dose regimen of a different product has advanced to phase 3 trials. Finally, the study suggests that future demand for an injectable PrEP by women may be greater in African than US settings, where the risk of HIV is highest.

Expanding Knowledge About Implementation of Pre-exposure Prophylaxis (PrEP): A Methodological Review

Methodological limitations in PrEP implementation studies may explain why PrEP implementation is lagging. This methodological review provides a description and critique of the methods used to identify barriers to PrEP implementation in the United States (2007-18). For each selected article, we provide: (1) research questions; (2) measures; (3) design; (4) sample (size and type); and (5) theoretical orientation. Among 79 articles which identified knowledge, attitudes, and behavioral and social/structural barriers to PrEP implementation, 51 (65%) were quantitative; 25 (32%) qualitative; and 3 (4%) were mixed-methods; overall, just one-half described a conceptual approach. About two-thirds of articles were conducted with patients and one-third with healthcare providers. Our review reveals a paucity of longitudinal, mixed-methods, and ethnographic/observational research and guiding theoretical frameworks; thus, the applicability of results are limited. We recommend that interventions aimed at PrEP implementation address barriers situated at multiple ecological domains, and thus improve PrEP access, uptake, and adherence.

"You Never Know What Could Happen": Women's Perspectives of Pre-Exposure Prophylaxis in the Context of Recent Intimate Partner Violence

BACKGROUND

Vulnerability to human immunodeficiency virus (HIV) infection is a significant public health issue for women experiencing intimate partner violence (IPV). Despite the increased risk of human immunodeficiency virus infection, women only represent 4.6% of pre-exposure prophylaxis (PrEP) users in the United States. IPV may present additional difficulties to PrEP access. In this qualitative study, we examined how IPV and the relational context shaped women's decisions, attitudes, and engagement in the PrEP care continuum.

METHODS

We conducted semistructured interviews with 19 women residing in Connecticut who participated in a prospective cohort study. We purposively recruited our sample to include women who reported physical and/or sexual IPV in the past 6 months, and used a grounded theory approach to analyze the qualitative data.

RESULTS

Our findings suggest multiple ways that the relational context can affect women's decisions, attitudes, and engagement in the PrEP care continuum. We identified five aspects of women's relationships that can shape women's interest, intentions, and access to PrEP: 1) relationship power struggles, 2) infidelity, 3) trust and monogamy, 4) male partner's reactions, and 5) "season of risk" (i.e., PrEP use only during times of perceived human immunodeficiency virus risk). Collectively, these findings suggest that women experiencing IPV might face additional relational challenges that need to be adequately addressed in settings administering PrEP.

CONCLUSIONS

Communication on sexual risk reduction strategies should address relational factors and promote women's autonomy. Future research on long-acting and invisible forms of PrEP may help to circumvent some of the relational barriers women experiencing IPV may face when considering PrEP care.

Differences in Medical Mistrust Between Black and White Women: Implications for Patient-Provider Communication About PrEP

Pre-exposure prophylaxis (PrEP) is an effective biomedical HIV prevention method. PrEP uptake has been persistently low among US women, particularly Black women, who account for 61% of new HIV diagnoses among women. Further understanding of barriers to Black women accessing PrEP is needed. This 2017 cross-sectional survey study explored race-based differences in PrEP interest and intention among women and the indirect association between race and comfort discussing PrEP with a healthcare provider through medical mistrust. The sample consisted of 501 adult women (241 Black; 260 White) who were HIV-negative, PrEP-inexperienced, and heterosexually active. Black women reported greater PrEP interest and intention than White women. However, Black women expressed higher levels of medical mistrust, which, in turn, was associated with lower comfort discussing PrEP with a provider. Medical mistrust may operate as a unique barrier to PrEP access among Black women who are interested in and could benefit from PrEP.

Awareness and Interest in HIV Pre-Exposure Prophylaxis Among Street-Based Female Sex Workers: Results from a US Context

Pre-exposure prophylaxis (PrEP) has the potential to be an empowering HIV prevention tool among female sex workers (FSW), yet little is known about PrEP awareness and interest in this population. Sex workers and Police Promoting Health in Risky Environments (SAPPHIRE) is a prospective cohort study of street-based FSW in Baltimore, MD. A cross-sectional analysis explored awareness and interest in PrEP among HIV-negative FSW. Multivariable Poisson regressions modeled associations between individual, interpersonal, and structural variables and PrEP awareness and interest. Of n = 232 FSW, 66% were white, half were less than 35 years old, 59% injected drugs daily, and 66% sold sex daily. Only 21% of FSW were aware of PrEP, though 74% were interested. PrEP awareness was associated with experiencing client condom coercion [adjusted incidence rate ratio (aIRR) = 0.50, 95% CI: 0.28-0.90] and condomless sex with an intimate partner (aIRR = 0.54, 95% CI: 0.30-0.98). PrEP interest was associated with perceiving PrEP as "very easy" to take (aIRR = 1.91, 95% CI: 1.49-2.45) and moving to an unfamiliar geographic area to sell sex (aIRR = 1.20, 95% CI: 1.04-1.39). Women who had a current gonorrhea or chlamydia infection were less likely to be interested in PrEP (aIRR = 0.75, 95% CI: 0.59-0.95). Though PrEP awareness among FSW is low, there are FSW who are significantly more likely to express interest in PrEP and outreach efforts should target these women. Results suggest that women-controlled HIV prevention methods may be important for reducing incidence among FSW.

Patient recommendations for PrEP information dissemination at family planning clinics in Atlanta, Georgia

OBJECTIVE

Family planning (FP) clinics are an ideal setting to disseminate information about pre-exposure prophylaxis (PrEP), but little is known about women's preferences for learning about PrEP in this setting.

STUDY DESIGN

We surveyed 500 women seeking care at 4 FP clinics in Atlanta. Before their provider visit, participants completed an HIV-risk screener. After, we asked participants about the HIV prevention counseling they received and how clinics could share information about PrEP. We performed descriptive analyses on demographics, HIV risk, and PrEP awareness/interest, and conducted thematic analysis on open-ended responses.

RESULTS

Only 18% knew about PrEP before the study; 28% of 376 sexually-active women had≥1 risk indicator consistent with PrEP eligibility. Three hundred forty seven women (69%) shared suggestions about how clinics should share PrEP information. We categorized suggestions into 4 themes - Advertising, Conversations, Awareness and Access. Participants (n=150) suggested clinics should advertise PrEP via brochures, posters, texts, or emails; 134 wanted providers to talk to patients about PrEP. Several (n=71) suggested sharing PrEP information broadly in the community and with other clinics/providers; others (n=11) wanted improved access to PrEP services.

CONCLUSIONS

Our results demonstrate overwhelming patient interest in learning more about PrEP through educational materials and directly from FP providers. Women were vocal about increasing PrEP awareness in the community, particularly among populations especially at risk for HIV (e.g., teens). These suggestions can be translated into actionable steps FP clinics can take to increase PrEP awareness and expand their reach to benefit women at risk for HIV.

IMPLICATIONS

High HIV rates among women in the South make it imperative to increase awareness of PrEP among women. Atlanta women seeking care in FP clinics valued learning about PrEP and recommended feasible strategies for disseminating information about PrEP in community settings, the clinic or during patient-provider discussion.

Beliefs About the End of AIDS, Concerns About PrEP Functionality, and Perceptions of HIV Risk as Drivers of PrEP Use in Urban Sexual Minority Men: The P18 Cohort Study

Using cross-sectional data from an ongoing cohort study of young gay, bisexual, and other men who have sex with men (N = 492), we examined the extent to which cognitive factors such as beliefs about the end of AIDS, concerns about the manner in which PrEP works, and perceptions about risk of contracting HIV, are related to PrEP uptake and use. While almost all participants indicted awareness of PrEP, a mere 14% had ever used PrEP. Those with lower concerns about the side effects of PrEP and greater belief that treatment and PrEP would eliminate AIDS were also more likely to have ever used PrEP. Our findings support the ongoing challenges of PrEP uptake as means of curtailing HIV in young sexual minority men, and suggest that beyond the structural factors, consideration must be given to further educating the population as a means of adjusting potentially faulty beliefs, concerns, and perceptions which may influence PrEP utilization.

PrEParing Women to Prevent HIV: An Integrated Theoretical Framework to PrEP Black Women in the United States

Preexposure prophylaxis (PrEP) with optimal adherence has demonstrated efficacy in reducing HIV incidence in women. Black women are disproportionately burdened by the HIV epidemic, accounting for more than half of all new HIV cases in women, thereby making PrEP an ideal prevention strategy for this group. However, to date, PrEP uptake by women in the United States has been slow. Further domestic research is needed to understand the multilevel factors related to PrEP awareness, uptake, and implementation in Black women. Our purpose was to review the current status of HIV prevention in Black women. We summarize clinical trials germane to federal approval of PrEP; discuss important PrEP studies focused on women, including non-oral options; and review multilevel barriers to PrEP uptake. Lastly, we discuss the use of an integrated theoretical framework to organize multilevel factors related to PrEP uptake by Black women in order to guide intervention development.

Exploring Gender Differences in PrEP Interest Among Individuals Testing HIV Negative in an Urban Emergency Department

PrEP is greater than 90% effective at preventing HIV infection, but many people who are vulnerable to HIV choose not to take PrEP. Among women, men who have sex with women (MSW) and men who have sex with men (MSM) who tested HIV negative in our emergency department, we assessed behavioral risk factors, self-perception of HIV risk, and interest in PrEP linkage. Women had lower odds of perceiving any HIV risk versus no risk than MSM, while Whites had greater odds of perceiving themselves as high risk than Blacks. Age and self-perception of risk were not associated with PrEP interest, but patients who were objectively classified as "at risk" had greater odds of interest in PrEP than those not at risk (p < .01). Discordance between HIV risk self-perception and objective risk demonstrates the limitation of relying on patient self-referral for PrEP based on their own subjective risk perception.

Oral Pre-Exposure Prophylaxis (PrEP) for HIV Prevention in Adolescents and Young Adults

Purpose of review

To review the literature about oral pre-exposure prophylaxis (PrEP) for HIV prevention, with specific focus on adolescents.

Recent findings

Use of PrEP reduces new HIV infections among men who have sex with men, heterosexuals, and people who inject drugs. One combination antiretroviral medication is approved for PrEP in the U.S. for adults. Limited data suggest that PrEP is safe for use in youth, although declines in adherence to PrEP over time suggest the need for adherence interventions specifically targeting youth. Safety concerns related to PrEP include potential negative impacts on bone density and renal function, as well as potential increases in riskier sexual behaviors. The U.S. Public Health Service has published guidelines for PrEP use in adults.

Summary

Current data suggest that PrEP use is safe in adolescents; however, further research is needed on the potential impact of long-term PrEP use on bone density and kidney function.

Examining the Impact of Intimate Partner Violence Type and Timing on Pre-exposure Prophylaxis Awareness, Interest, and Coercion

Previous research suggests that intimate partner violence (IPV) is associated with acceptability of and adherence to pre-exposure prophylaxis (PrEP). However, very few studies have examined whether the type (i.e., physical, sexual, and psychological IPV) and timing (i.e., lifetime, past-year) of IPV experiences differentially relate to PrEP awareness, interest, and perceived PrEP coercion. Therefore, the objective of this study is to examine associations between lifetime and past-year physical, sexual, and psychological IPV experiences on PrEP awareness, interest, and perceived PrEP coercion. Data were collected from an online survey administered to 210 women and men. Past-year physical IPV experiences (AOR 4.53, 95% CI 1.85, 11.11) were significantly associated with being interested in using PrEP. Lifetime sexual (AOR 3.69, 95% CI 1.62, 8.40), psychological IPV (AOR 4.70, 95% CI 1.01, 21.89), and past-year sexual IPV experiences (AOR 3.01, 95% CI 1.10, 8.27) were also significantly associated with believing a recent partner would attempt to control the participant's use of PrEP, if she or he were currently using it. Understanding that engaging in PrEP care is influenced differently by the type and timing of IPV has potential implications for PrEP candidacy guidelines and interventions.

HIV Risk perception and eligibility for pre-exposure prophylaxis in women involved in the criminal justice system

Women involved in the criminal justice system (WICJ) are at high risk of acquiring HIV and would benefit from HIV pre-exposure prophylaxis (PrEP) but there are no studies in this population to inform PrEP implementation programs. We conducted a cross-sectional survey of HIV-uninfected, cis-gender women on probation, parole and/or recently released from prison/jail to assess PrEP awareness, eligibility, potential barriers to uptake, and the PrEP care continuum. The 125 WICJ surveyed reported high rates of HIV risk behaviors including recent transactional sex (22.4%) and unsafe injection practices (14.4%). Despite 33% (n = 42) meeting eligibility criteria for PrEP, only 25% were aware of PrEP and one person was currently using it. Just 16.7% of those who were PrEP eligible perceived they were at risk for HIV. Following a brief explanation of PrEP, 90% said they would try it if recommended by their physician. Compared to those not PrEP eligible (n = 83), PrEP eligible women were less likely to be stably housed or have a primary care provider, and were more likely to be violence-exposed, charged with drug possession, have lifetime substance use, or living with Hepatitis C infection. WICJ frequently engage in HIV risk behaviors that make them eligible for PrEP. Uptake may be limited by lack of PrEP awareness or underestimation of personal HIV risk. WICJ report receptiveness to PrEP and represent an important population for targeted PrEP implementation programs.

Predictors of HIV, HIV Risk Perception, and HIV Worry Among Adolescent Girls and Young Women in Lilongwe, Malawi

BACKGROUND

Adolescent girls and young women (AGYW) in sub-Saharan Africa have high HIV prevalence and incidence. We sought to understand which HIV risk factors individually and in combination contribute to risk, and whether these factors are associated with HIV worry and risk perception.

SETTING

This study is ongoing at 4 public health centers in Lilongwe, Malawi (2016-2017).

METHODS

AGYW of 15-24 years old were recruited to participate in a study assessing 4 models of service delivery. At each health center, participants completed a baseline survey assessing socioeconomic, behavioral, biomedical, and partnership characteristics; self-reported HIV status; and, if HIV-uninfected, HIV risk perception (high versus low or none) and HIV worry (any versus none). We analyzed associations between baseline characteristics and HIV prevalence, risk perception, and worry.

RESULTS

Among 1000 AGYW, median age was 19 years (IQR: 17-21). Thirty-three participants reported being HIV-infected. Fifteen characteristics were associated with HIV infection. Having more risk factors was associated with higher HIV prevalence (≤4 factors, 0.5%; 5-8 factors, 6%; >8 factors, 21%). Having more risk factors was also associated with higher risk perception (P < 0.001) and higher worry (P < 0.001). However, among those with ≥8 risk factors, 52% did not consider themselves to be at high risk and 21% did not report any HIV worry.

CONCLUSIONS

Most AGYW perceive little risk of HIV acquisition, even those at highest risk. As a critical gap in the HIV prevention cascade, accurate risk perception is needed to tailor effective and sustained combination prevention strategies for this vulnerable population.

HIV Care Providers' Intentions to Prescribe and Actual Prescription of Pre-Exposure Prophylaxis to At-Risk Adolescents and Adults

Pre-exposure prophylaxis (PrEP) is indicated for use in US adults, and little is known about clinician intentions to prescribe and actual prescription of PrEP to adolescents younger than 18. Fifty-six clinicians who care for HIV-infected and at-risk youth completed an anonymous online survey in 2014. Primary outcomes were (1) intentions to prescribe PrEP to adolescents and adults in four risk categories [men who have sex with men (MSM), transgender women, heterosexuals with multiple partners of unknown HIV status, heterosexuals with HIV-infected partners]; and (2) actual prescription of PrEP to adolescents and adults in these risk groups. Independent variables included clinician characteristics, experience prescribing nonoccupational postexposure prophylaxis, familiarity with and knowledge of PrEP and PrEP guidance, attitudes toward PrEP, and facilitating factors for prescribing PrEP and incorporation of PrEP guidance into practice. Variables associated with intention to prescribe ("very likely to prescribe" vs. other responses) and actual prescription of PrEP stratified by age and risk category were identified in logistic regression models. Mean age was 45.9 years (standard deviation 10.7); 64% were physicians. More clinicians reported high intention to prescribe PrEP to adult versus adolescent MSM (p = 0.02) and transgender women (p = 0.001). Variables associated with intention to prescribe and prescription of PrEP differed by age and risk category. In adolescents, those variables included positive beliefs, higher number of facilitating factors, and fewer barriers to PrEP prescription. Designing strategies based on these findings that address both facilitating factors and barriers to PrEP prescription may improve PrEP uptake by at-risk youth.

A brief, trauma-informed intervention increases safety behavior and reduces HIV risk for drug-involved women who trade sex

BACKGROUND

Female sex workers (FSWs) are an important population for HIV acquisition and transmission. Their risks are shaped by behavioral, sexual network, and structural level factors. Violence is pervasive and associated with HIV risk behavior and infection, yet interventions to address the dual epidemics of violence and HIV among FSWs are limited.

METHODS

We used participatory methods to develop a brief, trauma-informed intervention, INSPIRE (Integrating Safety Promotion with HIV Risk Reduction), to improve safety and reduce HIV risk for FSWs. A quasi-experimental, single group pretest-posttest study evaluated intervention feasibility, acceptability and efficacy among FSWs in Baltimore, MD, most of whom were drug-involved (baseline n = 60; follow-up n = 39 [65%]; non-differential by demographics or outcomes). Qualitative data collected at follow-up contextualizes findings.

RESULTS

Based on community partnership and FSW input, emergent goals included violence-related support, connection with services, and buffering against structural forces that blame FSWs for violence. Qualitative and quantitative results demonstrate feasibility and acceptability. At follow-up, improvements were seen in avoidance of client condom negotiation (p = 0.04), and frequency of sex trade under the influence of drugs or alcohol (p = 0.04). Women's safety behavior increased (p < 0.001). Participants improved knowledge and use of sexual violence support (p < 0.01) and use of intimate partner violence support (p < 0.01). By follow-up, most respondents (68.4%) knew at least one program to obtain assistance reporting violence to police. Over the short follow-up period, client violence increased. In reflecting on intervention acceptability, participants emphasized the value of a safe and supportive space to discuss violence.

DISCUSSION

This brief, trauma-informed intervention was feasible and highly acceptable to FSWs. It prompted safety behavior, mitigated sex trade under the influence, and bolstered confidence in condom negotiation. INSPIRE influenced endpoints deemed valuable by community partners, specifically improving connection to support services and building confidence in the face of myths that falsely blame sex workers for violence. Violence persisted; prevention also requires targeting perpetrators, and longer follow-up durations as women acquire safety skills. This pilot study informs scalable interventions that address trauma and its impact on HIV acquisition and care trajectories for FSWs.

CONCLUSION

Addressing violence in the context of HIV prevention is feasible, acceptable to FSWs, and can improve safety and reduce HIV risk, thus supporting FSW health and human rights.

Pre-exposure prophylaxis for HIV prevention in women: current perspectives

There are ~900,000 new HIV infections among women every year, representing nearly half of all new HIV infections globally. In the US, nearly one-fifth of all new HIV infections occur among women, and women from racial and ethnic minority communities experience disproportionately high rates of new HIV infections. Thus, there is a need to develop and implement effective HIV prevention strategies for women in the US and internationally, with a specific need to advance strategies in minority communities. Previous studies have demonstrated that oral HIV pre-exposure prophylaxis (PrEP), the use of antiretroviral medications by HIV-uninfected persons to prevent HIV acquisition, can reduce HIV incidence among women who are adherent to PrEP. However, to date, awareness and uptake of PrEP among women have been very limited, suggesting a need for innovative strategies to increase the knowledge of and access to PrEP among women in diverse settings. This narrative review summarizes the efficacy and safety data of PrEP in women, discusses considerations related to medication adherence for women who use PrEP, and highlights behavioral, social, and structural barriers to maximize the effectiveness of PrEP in women. It also reviews novel modalities for PrEP in women which are being developed and tested, including topical formulations and long-acting injectable agents that may offer advantages as compared to oral PrEP and proposes a community-oriented, social networking framework to increase awareness of PrEP among women. If women are provided with access to PrEP and support to overcome social and structural barriers to adhere to PrEP, this prevention strategy holds great promise to impact the HIV epidemic among women in the US and globally.

Pre-exposure prophylaxis prescribing and retention in care among heterosexual women at a community-based comprehensive sexual health clinic

In the United States, heterosexual women account for 20% of new HIV infections. As a user-controlled HIV prevention method, pre-exposure prophylaxis (PrEP) has substantial potential to reduce new infections among women. However, among women, PrEP is vastly underutilized. To guide efforts to increase women-at-risk's PrEP use, we sought to describe the characteristics of women prescribed PrEP as well as their retention in PrEP care. We conducted a chart review of women who received care at a comprehensive sexual health clinic within a large urban health care system. Referral sources included the health care system's clinics and HIV testing program, as well as local community-based organizations. From 1 December 2014 to 5 August 2016, 554 women received care at the clinic. During this period, 21 heterosexual women (3.8%) received at least one prescription for daily oral PrEP. For women prescribed PrEP, median age was 35 years old (range: 20-52). The majority (66.7%) were either Latina or non-Latina Black and most (81.2%) had public health insurance. The most common PrEP indication was being in a known sero-discordant partnership (85.7%). Of women in such partnerships, 83.3% reported their male partner was currently taking antiretroviral medications (ARVs) and 16.7% reported trying to conceive with their partner (not mutually exclusive). Of women with ARV-using partners, 66.7% reported that their partners were virally suppressed. Retention in PrEP care at three months was 61.1% and, at six months, 37.5%. Further study is necessary to expand PrEP to women whose risk factors extend beyond being in a known sero-discordant partnership, and to understand the reasons for the observed drop-off in PrEP care visits in real-world settings.
