Identifying Motivators, Facilitators, and Barriers to Engagement and Retention in Anal Cancer Screening Among Men and Women with HIV in One Ryan White HIV/AIDS Clinic
Geba MC, Kalluri D, Mitchell EM, Flickinger T, Cardenas B, Dillingham R and Thomas TA
Anal squamous cell carcinoma disproportionally affects people with HIV (PWH); however, engagement in anal cancer screening is low in many settings. This study was conducted to assess knowledge and perceptions of anal cancer screening to identify factors in the engagement and retention in prevention services among PWH. Semistructured interviews were conducted among adult PWH eligible for anal cancer screening in our Ryan White HIV/AIDS Program clinic. Descriptive statistics were tabulated; thematic analyses were performed to identify emerging motivators, facilitators, and barriers. Among 26 PWH, 9 had not been screened, 8 had undergone Papanicolaou (Pap) testing alone, and 9 had undergone anoscopy. The median age of the cohort was 55.2 years; 54% identified as men who have sex with men, and 54% identified as Black. In the unscreened cohort, participants were motivated by investing in their health and positive attitudes toward cancer prevention however were deterred by a lack of referral and low awareness about screening. Among those who had Pap testing, trust in healthcare providers and abnormal testing results were motivators to engagement, whereas lack of perceived risk of anal cancer and worry about pain of an anoscopy were prominent barriers. Among those who had anoscopy, perceived risk, positive experience with the procedure, and use of anxiolytics prior to anoscopy were motivators, whereas anxiety around a new cancer diagnosis and negative experience with anoscopy were barriers. Clinics seeking to build or strengthen their anal cancer screening programs can address the barriers described in this study to promote access to anal cancer screening among PWH.

This study evaluates the impact of an expanded HIV testing initiative, launched in June 2018 in Luzhou, Sichuan, China, on antiretroviral therapy (ART) initiation rates among people living with HIV (PLWH). Using an uncontrolled interrupted time-series design, we analyzed data from 11,040 PLWH between June 2016 and December 2022, extracted from 108 health facilities via the Center for Disease Control and Prevention's ART database. The primary outcome measures were ART initiation rates within 7 and 30 days of HIV diagnosis. Results showed a significant improvement in the 30-day ART initiation rate following expanded testing, increasing from 46.1% to 90.9% by the study's end. The 7-day initiation rate also improved but remained below 30%. The study found that expanded testing enhanced the role of primary health care institutions in ART initiation. However, the COVID-19 pandemic, beginning January 2020, negatively impacted ART initiation rates, with a slight effect on 30-day rates but a persistent negative impact on 7-day rates. Despite these challenges and an increased HIV burden, Luzhou's ART initiation rates surpassed the national average. This study emphasizes the effectiveness of expanded HIV testing in ensuring timely ART access, crucial for HIV epidemic control, and improved patient outcomes. It also reveals challenges in maintaining HIV services during public health crises, offering insights into health care system resilience. Future research should focus on evaluating long-term treatment outcomes and strategies to support ending the AIDS epidemic.
Pre-Exposure Prophylaxis for the Prevention of HIV-1: An Assessment of Oral Pre-Exposure Prophylaxis Usage Patterns, First Evidence of HIV-1, and HIV-1 Risk Factors in the United States
Oglesby A, Germain G, Metzner AA, Laliberté F, MacKnight SD, Hilts A, Swygard H and Duh MS
In clinical trials, once-daily oral tenofovir-based pre-exposure prophylaxis (PrEP) significantly reduced HIV-1 acquisition risk; however, this was highly dependent on medication adherence and persistence. We report clinical characteristics, PrEP usage patterns, first evidence of HIV-1, and associated risk factors among adults with commercial insurance using oral PrEP in the United States using health plan claims from the IQVIA PharMetrics® Plus database between January 1, 2015, and March 31, 2020, from individuals who newly initiated emtricitabine/tenofovir disoproxil fumarate (FTC/TDF) or FTC/tenofovir alafenamide (TAF) for daily PrEP. Overall, 25,419 individuals were included (FTC/TDF, = 24,232; FTC/TAF, = 1187), with generally similar characteristics reported during the 6-month baseline period across cohorts. Mean follow-up length was 504 and 77 days for FTC/TDF and FTC/TAF, respectively, corresponding with the 2019 approval of FTC/TAF for PrEP. Similarly, mean PrEP use duration was 354 and 68 days for FTC/TDF and FTC/TAF, respectively. PrEP breaks (>90-day gap) were observed in 11.1% of individuals using FTC/TDF, with a mean break duration of 249 days; 20.0% of individuals using FTC/TDF and 7.3% using FTC/TAF had ≥1 sexually transmitted infection diagnosis during follow-up. From 6 to 12 months of follow-up, mean FTC/TDF proportion of days covered (PDC; 0.74 vs. 0.67) and persistence (70.2% vs. 57.4%) decreased; real-world PDC and persistence were lower than reported in globally conducted clinical trials. First evidence of HIV-1 was infrequent among individuals using FTC/TDF (0.6%), though 60.3% had PrEP on hand when HIV-1 definition was met; high-risk sexual behavior, syphilis, and gonorrhea were the most important risk factors.
A Pilot Randomized Control Trial of the Motivational Interviewing to Increase PrEP Uptake Intervention Among Black Women in the United States
Dale SK, Petrulla V and Wright IA
Despite the disproportional impact of HIV, Black individuals are benefiting the least from pre-exposure prophylaxis (PrEP). Motivational interviewing (MI) for PrEP uptake (MI-PrEP) is a two-session culturally tailored intervention incorporating MI strategies to improve PrEP motivation and uptake among cisgender Black women. A pilot randomized control trial was conducted in the Southeastern United States, and 41 women were randomized to MI-PrEP (session 1 with PrEP psychoeducation and MI and session 2 with MI and light case management) or enhanced treatment as usual (ETAU; two sessions of PrEP psychoeducation [videos explaining PrEP]). Women completed one follow-up assessment (1 month after visit 2). Measures captured primary (motivation [via contemplation and readiness ruler] and PrEP uptake via medical records) and secondary outcomes (e.g., PrEP knowledge, barriers to PrEP, and speaking to a provider about PrEP). Difference-in-differences analyses comparing MI-PrEP with ETAU as well as -tests for within-group changes over time were conducted. Women who completed MI-PrEP (90.5% retained) compared with ETAU (100% retained) had a significantly higher likelihood of speaking to a provider about PrEP (OR = 4.42e7, CI [8.55e6, 2.29e8], DiD = 17.60, se = 0.84, < 0.001). Within the MI-PrEP group, women had significant increases in PrEP prescription, knowledge, and motivation/contemplation, and significant decreases in financial resources as a PrEP barrier and medical mistrust (MMT). ETAU had within-group increases in PrEP prescription and speaking to a provider, no changes in motivation and MMT, and increases in specific barriers to care (e.g., transportation). MI-PrEP shows promise, and a large-scale study may be beneficial to further assess efficacy and examine implementation.

Mbuntcha Bogni F, Kentish S, Tran BN, Araia ES, Krahn T, Bayliss G, Flanigan TP and Gillani FS
Antiretroviral therapy (ART) has significantly improved mortality rates for individuals living with HIV, but kidney disease remains prevalent, especially among older adults. Our study analyzed the burden of kidney disease in individuals aged 65 and older at The Miriam Hospital Immunology Center in Rhode Island. We calculated estimated glomerular filtration rates using the last creatinine values from 2019 and identified chronic kidney disease (CKD) stages. Results showed a 19% prevalence of moderate or severe CKD among adults living with HIV, rising to 39% for those aged 75 and older. Particularly striking was the increased prevalence among African American adults aged 65+, at 30.4%, rising to 50% for those over 75. In comparison, the National Institute of Diabetes and Digestive and Kidney Diseases reports that CKD stage 3 affects 20.1% of adults aged 65+, compared with just 1.2% in those younger than 65. Gender and racial disparities are evident; CKD stage 3 is more prevalent in females (5.8%) than males (4.4%). Our findings indicate that 32% of HIV-positive females have moderate-to-severe kidney disease, compared with 14% of males. Importantly, we did not account for hypertension, diabetes, and hepatitis C virus infection, which may influence renal outcomes. Our study shows that ART has reduced mortality, as more people with HIV now live longer, while also revealing the disproportionate burden of kidney disease among older adults and racial minorities, as well as a concerning trend among women; therefore, emphasizing the need for targeted health care strategies for high-risk groups.

Knowledge, Attitudes, and Perspectives of Women Who Have Migrated from Sub-Saharan Africa to France Toward HIV Pre-Exposure Prophylaxis in a Family Planning Center
Liegeon G, Devlin SA, Manda V, Castaneda J, Marsh C, Ridgway JP and Johnson AK
Women who have migrated from sub-Saharan Africa (SSA) are underrepresented among HIV pre-exposure prophylaxis (PrEP) users in France (∼2%), yet they account for around 20% of new HIV infections annually. We conducted focus groups to explore the knowledge, attitudes, and perspectives of these women toward PrEP in a French family planning center (FPC). Focus groups occurred from November 2023 to February 2024 within the Lariboisière Hospital FPC in Paris. The social ecological model informed the discussion guide, which explored women's PrEP experiences and determinants for uptake on various levels. Five focus groups were conducted ( = 19). The median age of participants was 29 [interquartile range (IQR) 28-37]. Eight African countries were represented. The average time in France since migration was 3 (IQR 1-6) years. The majority of women had never heard of PrEP but expressed strong interest in learning more about it. Women underscored the difficulty of negotiating HIV prevention tools with their partners, risks from transactional sex, and barriers to PrEP use such as adherence challenges to daily pills and misconceptions about HIV transmission. There was strong interest in long-acting injectable PrEP. Women reported high trust in FPC providers and viewed the FPC as an ideal location to access PrEP. Conspiracy theories, cultural beliefs, and anticipated stigma were also identified as barriers to PrEP uptake. Most women advocated for disseminating PrEP information to their peers using diverse community outreach strategies. Despite a strong interest, increasing PrEP uptake in women from SSA will remain challenging without multi-faceted and adapted implementation strategies.

Co-Creation of Patient-Centered Metrics for Long-Term Well-Being Involving People with HIV and HIV Care Providers
White TM, Gresle AS, Roqueta J, Pine C and Lazarus JV
Achieving viral suppression alone does not fully resolve the multifaceted health challenges faced by people with HIV (PWH), such as early aging, multimorbidity, and low health-related quality of life. This co-creation pilot study to investigate patient-centered metrics for long-term well-being involved the development of a knowledge, attitudes, and practices survey through focus groups and its implementation among HIV care providers in Barcelona, Spain, in 2024. A collaborative approach of involving PWH from the community was essential in ensuring the relevance of the identified issues. The results underscored the importance of monitoring comorbidities such as mental health issues, cardiovascular diseases, and neurological disorders, alongside the use of patient-reported outcome measures (PROMs) and patient-reported experience measures (PREMs). The findings highlighted several barriers to implementing PROMs, including time constraints, patient health literacy, and technical issues. Overall, the study emphasizes the need for health systems in Barcelona, Spain, to integrate PROMs and PREMs into routine HIV care to enhance patient-centered care and address the comprehensive well-being of PWH.
Acceptability and Feasibility of Implementing a Home-Based HIV Pre-Exposure Prophylaxis Program in an Urban Clinic
Yuh T, Lalley-Chareczko L, Zanders D, Shaw H, Spencer T, Serafin D, Koenig H and Momplaisir F
Personal and structural barriers to HIV pre-exposure prophylaxis (PrEP) care result in its underutilization and premature discontinuation. A home-based PrEP program comprised of telemedicine visits and/or self-administered lab testing may address some of these barriers. Our objective was to assess the acceptability and feasibility of a home-based PrEP program among stakeholders at an urban HIV and primary care clinic. We used the consolidated framework for implementation research to evaluate determinants of successful implementation of the program. We surveyed and interviewed PrEP patients and their health care team. In a baseline survey of PrEP users ( = 112) administered between May 2021 and August 2022, 65% expressed interest in switching to the home-based PrEP program. Seventeen patients over the course of follow-up through December 2023 started home-based PrEP, including 12 patients who completed both a telemedicine visit and a self-administered lab kit, and 5 patients who completed only a telemedicine visit. Of these, over 80% had positive feedback on the telemedicine visits. Survey results demonstrated excellent acceptability and feasibility of the lab kits. Patients indicated in interviews that the home-based PrEP program provided the strong advantage of convenience. Despite mixed feelings from PrEP providers on telemedicine visits ( = 5), most felt that the program made PrEP care delivery easier for patients and would encourage their patients to use the program if it were a good fit. Barriers to program success included shipping delays and staff turnover during program implementation. In conclusion, uptake of the home-based program was low but program participants expressed high acceptability.

Perceived Versus Actual Costs of HIV Pre-Exposure Prophylaxis Among Gay, Bisexual, and Other Men Who Have Sex with Men in the United States
Dawit R, Predmore Z, Raifman J, Chan PA and Dean LT
Gay, bisexual, and other men who have sex with men (GBMSM) account for the highest proportion of HIV diagnoses in the United States, with daily pre-exposure prophylaxis (PrEP) significantly reducing transmission risk. Since 2021, the Affordable Care Act rules have required PrEP and accompanying care visits to be free for most Americans; nevertheless, insurers have found ways to circumvent no-cost PrEP and some employers are receiving exemptions from including it in their formularies. Despite this, perceived costs and indirect expenses still hinder PrEP adoption. This study examines the differences between perceived and actual costs among GBMSM who have and have not used PrEP. We conducted a one-time online survey with 692 adults from six New England states between May 2020 and October 2021. Participants who had never used PrEP estimated its cost, while those with prior PrEP experience reported their actual expenses. Bivariate analysis and multi-variable logistic regression were used to assess the data. Results showed a 60% difference between perceived ($48) and actual ($30) median monthly costs. Higher perceived costs among nonusers were linked to race and income, while high actual costs for prior users were associated with insurance type, income, wealth, race, and self-rated consumer credit. This significant disparity in PrEP cost perceptions highlights the need for targeted outreach and messaging to improve PrEP uptake among at-risk populations who have not yet accessed it.
Sexual Health of Young Adults Living with Perinatally Acquired HIV in Paris, France: A Qualitative Study
Ibrahim N, Viard JP, Ludot-Grégoire M, Lachal J, Dumas A, Brazille P, Lechat D, Bridou S, Molinari D, Hassler C and Rouquette A
We aimed to explore the sexual health of young adults with perinatally acquired human immunodeficiency virus (PHIV). Eighteen to 25 years old PHIV participants were recruited in two tertiary care units in Paris. Sexually transmitted HIV was an exclusion criterion. Individual interviews were conducted. Transcripts were analyzed using a semio-pragmatic phenomenological method. Twenty-five participants were interviewed from March 2022 to September 2022. Some of them renounced being in any romantic relationship. Those who disclosed their HIV status to their romantic partner reported that dating was more complex and those who did not disclose reported that keeping HIV a secret was a significant mental burden. Young men tended to disclose their HIV status to their romantic partner whereas young women did not consider doing so before marriage. Many participants had to educate themselves about sexuality, through school or websites. Identified interlocutors for sexuality varied across participants. All participants were aware of U = U (Undetectable = Untransmittable) slogan. Despite that, participants remained worried about transmitting HIV to their sexual partners. That hindered their sexual satisfaction. In addition, they neglected the risk of unwanted pregnancies or sexually transmitted diseases (STDs). In our study, knowing the U = U slogan did not provide reassurance to PHIV participants regarding the risk of onward HIV transmission. Further, they showed very little concern for protecting themselves from their partner's STD.

A Systematic Review of Factors Associated with COVID-19 Vaccine Uptake, Hesitancy, and Acceptability Among Adults with HIV: Implications for Integrating COVID-19 Immunization into HIV Care
Gray A, Alemohammad SY, Ramírez-Ortiz D and Trepka MJ
The COVID-19 virus, once a public health emergency, is now endemic. Immunization remains an important measure for mitigating high levels of disease, morbidity, and mortality related to COVID-19 infection. People with HIV (PWH), in particular, benefit from COVID-19 vaccination because of increased risk for severe COVID-19 infection. However, previous data suggest vaccine hesitancy among this population. Given this context and the evolving epidemiology of COVID-19, this review examines factors associated with COVID-19 vaccine hesitancy, acceptability, and uptake among adults with HIV. Through a systematic search of electronic databases, we identified 56 peer-reviewed articles published between the years 2020 and 2023 that matched the objectives of our review out of a total of 797 screened citations. Among our final sample of articles, nearly all global regions were represented, and 61% of studies recruited only PWH. We identified eight categories of factors associated with COVID-19 vaccination outcomes, including HIV-specific factors (e.g., CD4 count), vaccine attitudes (e.g., vaccine confidence), factors related to the COVID-19 virus (e.g., concern about infection), factors specific to the COVID-19 vaccine (e.g., accessibility), social norms and peer factors (e.g., subjective norms), mental health (e.g., anxiety/depression) and other psychological factors (e.g., substance use), demographic characteristics (e.g., age), and health factors (e.g., vaccination history). Reflecting on these factors, we discuss populations in need of vaccine promotion, modifiable targets for intervention, and integrating immunization into HIV care. Public health efforts to promote COVID-19 immunization among PWH must include educational/informational, peer, and structural interventions and must now consider uptake of COVID-19 booster doses.
The Impact of Stigma on Self-Management Behavior Among People with HIV in China: The Role of Social Support and Self-Esteem
Huang H, Zhang L, Tu L, Zhang X, Zhong H, Liu Q, Liu Y and Chen H
Understanding the psychosocial factors influencing self-management behaviors among people with HIV (PWH) is crucial for effective medical interventions and improving their quality of life. However, there has been limited research exploring the psychosocial mechanisms influencing self-management behaviors among PWH in China. Our study examined the relationship between stigma, social support, self-esteem, and self-management behaviors among PWH, as well as whether social support and self-esteem mediate these relationships. Cross-sectional data were collected from 282 PWH in Sichuan Province, China. Data were collected using four validated self-report measures (HIV Stigma Scale, HIV/AIDS Patient Self-Management Scale, Social Support Rating Scale, and Self-Esteem Scale). Structural equation modeling was used to examine the different pathways influencing self-management behaviors. All the impacts on self-management behavior outcomes were found to be significant. The final mediation model indicated that social support and self-esteem significantly mediated the relationship between stigma and self-management behaviors. These findings underscore the importance of addressing stigma and enhancing social support and self-esteem in interventions aimed at promoting self-management behaviors among PWH.
Reported Side Effects and Adherence of Daily HIV Pre-Exposure Prophylaxis Users in Ontario, Canada: An Analysis of the Ontario Pre-Exposure Prophylaxis Cohort Study
Rudd M, McGarrity M, Lisk R, MacPherson P, Knox D, Woodward K, Reinhart J, MacLeod J, Bogoch II, Clatworthy D, Biondi MJ, Sullivan S, Li A, Durrant G, Schonbe A, Ongoiba F, Burchell AN and Tan DHS
Side effects are a common concern of current and potential HIV pre-exposure prophylaxis (PrEP) users, potentially leading to missed doses. We examined the relationship between reported side effects and adherence in the Ontario PrEP Cohort Study (ON-PrEP). In total, 600 predominantly gay (87.3%), White (65.8%), and male (95.0%) participants completed questionnaires assessing the presence and severity of five side effect categories (nausea, diarrhea, headache, abdominal pain, and "other") as well as their adherence to daily PrEP (any missed doses in the previous 4 days). In total, 175 participants (29%) ever reported experiencing side effects: most commonly diarrhea (7.5% of study visits), and most were of mild severity. Lower incomes ( = 0.01), identifying as bisexual ( = 0.04), and baseline concern about side effects ( < 0.001) were associated with ever reporting side effects. The odds of reporting any side effects decreased by a factor of 0.44 (95% confidence interval 0.25-0.80) with each additional year of PrEP use, however 1 in 10 participants still reported side effects after 1 year of use. The odds of reporting optimal adherence were 0.48 (0.28-0.83) times lower for participants reporting any side effects, 0.67 (0.51-0.89) times lower per additional side effect category reported, and 0.78 (0.65-0.97) times lower per incremental increase in side effect severity ratings. We found some evidence of interaction between side effect measures and duration of PrEP use, suggesting that these relationships were stronger for participants taking PrEP for longer. Clinicians should make efforts to ascertain patients' experience of side effects and consider risk counseling and alternative PrEP regimens to promote adherence.
Knowledge and Attitudes About HIV Pre-Exposure Prophylaxis Among Sexually Active Black and Latina Cisgender Women: Findings from the 2017 and 2018 New York City Sexual Health Survey
Price DM, Garretson M, Cai X, Miah F, Scanlin K, Blackstock O and Edelstein Z
Pre-exposure prophylaxis (PrEP) is a highly effective tool to prevent HIV, yet it is underutilized among women. The current study aims to evaluate the awareness, attitudes, and perceptions of PrEP among a large survey sample of Black and Latina women in New York City (NYC). Interviewer-administered surveys were conducted in high HIV incidence neighborhoods in NYC among Black, Latina, and Afro-Latina women who reported recent sex with a man in 2017 ( = 398) and 2018 ( = 405). About 40% of participants were aware of PrEP, whereas 30.4% indicated interest in using it. The top reason for not utilizing it was low HIV risk perception. However, most participants supported the idea that using PrEP meant asserting control over their health (94.1%). Primary care providers and obstetricians/gynecologists were participants' preferred sources for PrEP (91.6%). Across survey cycles, compared to non-Black Latina participants, Black participants had significantly higher PrEP awareness (44.4% vs. 29.1%). PrEP awareness was also significantly higher among survey participants in 2018 (45.2%) than in 2017 (34.3%). Less than half of the participants were aware of PrEP, but those who were aware expressed largely positive attitudes toward the medication. Our findings may inform future PrEP implementation strategies to optimize awareness and access to PrEP among women disproportionately affected by HIV, like focusing on personal empowerment instead of risk-based messaging and training women's sexual health care providers in PrEP provision.
Interventions for Improving HIV Care Continuum Outcomes Among LGBTQ+ Youth in the United States: A Narrative Review
Dorfman M, Goldhammer H, Krebs D, Chavis NS, Psihopaidas D, Moore MP, Downes A, Rebchook G, Cahill S, Mayer KH and Keuroghlian AS
Lesbian, gay, bisexual, transgender, queer, and all sexually and gender diverse (LGBTQ+) youth with HIV face multiple barriers to progression along the HIV care continuum. We searched PubMed, PsycInfo, clinicaltrials.gov, and the Adolescent Medicine Trials Network for HIV/AIDS Interventions for interventions focused on improving linkage to care, retention in care, adherence to antiretroviral therapy, or viral suppression (VS) among LGBTQ+ youth with HIV in the United States. Included studies were published in English between January 1, 2017 and December 31, 2022, took place in the United States, and had samples with a minimum age of 12 years, a median or mean age of 24 years or less, and with ≥50% reporting an LGBTQ+ identity. Our search identified 11 interventions that met our criteria, of which only three were designed and tailored exclusively for LGBTQ+ populations. Interventions used a variety of modalities, including remote electronic delivery, in-person delivery, or both. Interventions most commonly aimed to enhance self-efficacy, HIV health knowledge, and medication self-management to facilitate improvements in HIV care continuum outcomes. Only two interventions showed statistically significant improvements in VS. More interventions tailored for LGBTQ+ youth are needed to end the HIV epidemic in the United States.

Peer Influence on Motivation to Use Pre-Exposure Prophylaxis Among Latino Sexual Minority Men in Miami, Florida: A Network Autocorrelation Model
Shrader CH, Craker L, Johnson AL, Rodriguez E, Skvoretz J, Self KJ and Kanamori M
Despite the availability of pre-exposure prophylaxis (PrEP), Latino sexual minority men (LSMM) continue to experience disparities in PrEP uptake and subsequently, HIV vulnerability. Social network norms are an underutilized solution to increase PrEP uptake. We used a peer influence model (network autocorrelation model) to examine the role of social network descriptive norms (i.e., actual behaviors) surrounding PrEP use. A total of 11 sociocentric networks of 13 friends ( = 143 LSMM) were recruited into our study from 2018 to 2019 in South Florida. Most participants were in PrEP pre-contemplation ( = 44), and almost one-third of our sample were using PrEP ( = 38). Three network autocorrelation models were estimated using an empirically informed Bayesian analysis. We found a positive association between participants' Motivational PrEP Cascade (MPC) position and their network members' (friends') cascade position based on three different measures of connection even when accounting for PrEP knowledge: friendship ( = 0.22; 95% CI = 0.01-0.42), emotional closeness ( = 0.24; 95% CI = 0.03-0.44), and frequency of interaction ( = 0.22; CI = 0.03-0.42). Our findings highlight that an individual's progress in the MPC may be influenced by their network members' progress in the MPC, suggesting that LSMM using PrEP may serve as role models to their peers for PrEP use due to descriptive norms. Our findings further suggest that PrEP interventions for LSMM along the MPC can be implemented at the social network level.
