Gay, bisexual, and other men who have sex with men (GBM) are disproportionately affected by the HIV epidemic. Despite the promise of pre-exposure prophylaxis (PrEP) in reducing HIV transmission risk, barriers for uptake and persistence exist. We sought to identify whether GBM in a nationwide cohort who have not yet initiated PrEP (n = 906) would prefer to get PrEP-related care from a primary care provider (PCP) compared to a specialist clinic or provider. We then sought to identify their level of interest and factors associated with preference for using home-based PrEP services (i.e., HB-PrEP), defined to participants as conducting HIV/STI self-testing from home with PrEP prescription mailing after an initial in-person clinic visit. We examined the associations of demographics, sexual HIV transmission risk, concern about frequent medical checkups associated with PrEP, health care access, and PrEP intentions with preferences for healthcare provider type and HB-PrEP. Concern about frequent medical checkups were associated with preferring a PCP for PrEP-related care, but men who perceived a barrier to bringing up the topic of PrEP with a doctor preferred a specialist clinic or provider more than a PCP. HB-PrEP was more appealing for younger men and those engaged in sexual HIV transmission risk, suggesting HB-PrEP could help reach GBM most vulnerable to HIV and in need of PrEP. HB-PrEP expansion has potential to increase PrEP uptake and persistence among GBM, particularly for men with barriers to clinic-based care and higher intentions to initiate PrEP. Clinical guidelines regarding HB-PrEP are needed to expand its use.

Intramuscular cabotegravir for long-acting injectable HIV pre-exposure prophylaxis (i.e., LAI-PrEP) was approved by the U.S. FDA in 2021. We sought to explore LAI-PrEP decision-making among a nationwide sample of young sexual minority men (YSMM) 17–24 years old. In 2020, HIV-negative/unknown YSMM (n = 41) who met CDC criteria for PrEP were recruited online to participate in synchronous online focus groups eliciting preferences and opinions about LAI-PrEP, as well as the impact of a potential self-administered option. Data were analyzed using inductive and deductive thematic analysis with constant comparison. Preferences and decision-making about LAI-PrEP varied widely among YSMM, with participants frequently comparing LAI-PrEP to oral PrEP regimens. We identified five key themes related to LAI-PrEP decision-making including concerns about adherence to PrEP dosing and clinic appointments, awareness and knowledge of PrEP safety and efficacy data, comfort with needles, minimizing PrEP stigma, and considerations of self-administration. YSMM acknowledged more PrEP options as beneficial to supporting uptake and persistence.

Introduction
Cervical cancer continues to pose a major public health challenge in low-income countries. Cervical cancer screening programs enable early detection and effectively reduce the incidence of cervical cancer as well as late-stage diagnosis and mortality. However, screening uptake remains suboptimal in Uganda. This study assessed correlates of intention to screen for cervical cancer among women in the Kyotera district of Central Uganda.
Methods
We analyzed cross-sectional data collected to determine the effectiveness of community audio towers (CATs) as a modality of health communication to support cervical cancer prevention. Women (
n
= 430) aged 21–60 years without a prior history of cervical cancer screening were surveyed about demographics, sources of health information and cervical cancer screening intentions in 2020. We used generalized linear modelling with modified Poisson regression and backwards variable elimination to identify adjusted prevalence ratios and 95% confidence intervals (CI) to determine factors associated with intention to screen for cervical cancer.
Results
Half (50.2%) of the participants had intentions to screen for cervical cancer within twelve months and 26.5% had moderate knowledge about cervical cancer. Nearly half (46.0%) considered themselves at risk of cervical cancer. Compared to residents who primarily received their health information from social media and radio, participants who received health information primarily from CATs (aPR:0.64, 95% CI:0.52–0.80,
p
< 0.001) and TV (aPR:0.52, 95% CI:0.34–0.82,
p
= 0.005) had a lower prevalence of intention to screen for cervical cancer. The prevalence of intentions to screen for cervical cancer in twelve months was higher among those resided in town councils (aPR:1.44, 95% CI:1.12–1.86,
p
= 0.004) compared to rural areas, and higher among those who considered themselves to be at risk of cervical cancer (aPR:1.74, 95% CI:1.28–2.36,
p
< 0.001) compared to those who did not.
Conclusions
We found suboptimal prevalence of intentions to screen for cervical cancer among women in central Uganda. Additional research and implementation projects are needed to increase cervical cancer screening. Targeting risk perceptions and behavioral approaches to increase intentions could be effective in future intervention work. Based on urban-rural differences, additional work is needed to support equitable sharing of information to support cancer prevention messaging; CATs and TV may best help reach those with lower intentions to screen based on our research.

Epidemiological trends in the United States have shown an increase in HIV cases among young sexual minoritized men. Using mobile health (mHealth), which refers to health services and information delivered or enhanced through the internet and related technologies, is a crucial strategy to address HIV disparities. However, despite its potential, the practical implementation of mHealth remains limited. Additionally, it is important to consider that young individuals may become accustomed to, distracted from, or lose interest in these apps, highlighting the need for regular updates and monitoring of relevant content.
In this study, we sought to highlight the voices of young sexual minoritized men aged 17-24 years and explored preferred mHealth intervention characteristics and willingness to adopt these technologies among a diverse, nationwide sample of young sexual minoritized men.
From April to September 2020, we recruited participants through web-based platforms such as social media and geosocial networking apps for men. These individuals were invited to participate in synchronous web-based focus group discussions centered around topics pertaining to HIV testing and prevention and their preferences for mHealth technologies.
A total of 41 young sexual minoritized men, aged between 17 and 24 years, participated in 9 focus group discussions spanning April to September 2020, with 3-7 participants in each group. The findings shed light on three key insights regarding young sexual minoritized men's preferences: (1) the need for personalized and representative content, (2) a preference for mobile and web-based simulation of prevention scenarios, and (3) a preference for digital software with individually tailored content. As expected, preference for mHealth apps was high, which supports the potential and need to develop or adapt interventions that use smartphones as a platform for engaging young sexual minoritized men in HIV prevention. This study expands on previous research in multiple meaningful ways, delving into the use and perceptions of mHealth information amid the COVID-19 pandemic. This study also highlighted the importance of streamlined access to health care providers, especially in light of the barriers faced by young people during the COVID-19 pandemic. In terms of presentation and navigation, participants favored a user-friendly design that was easy to use and appropriate for their age, which was effectively addressed through the implementation of web-based simulations.
Ultimately, this study provides valuable insight into the preferences of young sexual minoritized men when it comes to mHealth interventions and highlights the need for further research in order to develop effective and tailored HIV prevention tools. A future direction for researchers is to evaluate how best to address participants' desire for personalized content within mHealth apps. Additionally, as technology rapidly evolves, there is a need to re-assess the effectiveness of web-based simulations, particularly those that are used in HIV prevention.

Patient-delivered partner therapy (PDPT) is an evidence-based method of partner treatment, but further research was needed to understand theoretical underpinnings of potential PDPT use.
We sought to develop and test a theoretical framework to understand PDPT intentions.
A Midwestern sample of sexually transmitted infection clinic patients were recruited to participate in a three-phase study incorporating semi-structured interviews (n = 20, total), cognitive interviews (n = 5), and surveys (n = 197; Mage = 31.3, 61% male, 91% Black or African-American). Thematic analysis was conducted to identify major themes, which guided development and testing of a theoretical framework on PDPT intentions using structural equation modeling.
We identified themes of information (knowledge); motivation (individual and partner protection beliefs, partner and provider motivation-to-comply); social support (sexual health and general); and behavioral skills (partner notification, medication delivery, and communication skills self-efficacy) in thematic analysis. The developed Interpersonal-Behavior model demonstrated good model fit in structural equation modeling [χ2(36) = 95.56, p<0.01; RMSEA = 0.09 (0.07-0.11, 90%C.I.); CFI = 0.94; SRMR = 0.05]. Information was associated with motivation (β = 0.37, p<0.001) and social support (β = 0.23, p = 0.002). Motivation was associated with social support (β = 0.64, p<0.001) and behavioral skills (β = 0.40, p<0.001), and social support was associated with behavioral skills (β = 0.23, p = 0.025). Behavioral skills were associated with higher PDPT intentions (β = 0.31, p<0.001), partially mediated the association of motivation with intentions (βdirect = 0.53, p<0.001; βindirect = 0.12, 95%CI: 0.03-0.30), and fully mediated the association of social support with intentions (βindirect = 0.07, 95%CI: 0.00-0.21).
The Interpersonal-Behavior model seems appropriate for PDPT intentions but should be tested longitudinally with PDPT outcomes and other interpersonal health behaviors.

Background
HIV self-testing (HIVST) has shown the potential for reaching people with heightened vulnerability to HIV, including young sexual minority men (YSMM), yet implementation of HIVST among YSMM aged 17–24 is scarce as a prevention method. Moreover, despite the consistent finding that offering HIVST increases HIV testing rates, barriers remain that need to be reduced in order to maximize the potential of this biomedical technology. Such information is necessary to direct implementation efforts to increase HIVST among YSMM, including HIV counseling and linkage to care. The current study was therefore intended to investigate perspectives for HIVST among YSMM and how HIVST can be marketed to increase implementation.
Methods
Between March and September 2020, we enrolled 41 YSMM to participate in one of nine online synchronous focus group discussions about their general experience with HIV preventive services. Guided by the Consolidated Framework (CFIR) for Implementation Research, we explored YSMM perspectives on facilitators and barriers to HIVST implementation. Data were analyzed using a deductive thematic content analysis approach.
Results
Many participants had never used HIVST before their participation in this study (n = 30; 73.2%). Qualitative results exhibited a variety of implementation determinants across the five CFIR 2.0 domains. Barriers included concerns about the format in which the testing materials would be provided (i.e., nature of packaging) and about the method in which the sample would need to be collected, particularly for those who had the testing kit mailed to their home address. These reservations were nested in the fear of unwanted disclosure of their sexual behavior, namely among the respondents who had to cohabitate with family due to the COVID-19 pandemic. Participants also discussed the limited local resources for HIVST. Many participants suggested programs that could be implemented to support HIVST, such as collaborations with trusted community agencies.
Conclusions
Understanding YSMM’ perspectives of HIVST may help identify implementation deficiencies within the delivery system and aid the development of implementation strategies to promote reach of HIVST.

Introduction:
A large percentage of people who inject drugs (PWID) are living with HIV. Yet, rates of HIV pre-exposure prophylaxis (PrEP) use among PWID remain low. Stigma surrounding substance use and PWID have been identified as potential barriers to PrEP. This study examined healthcare providers’ concerns regarding PWID and willingness to prescribe PrEP to PWID.
Methods:
An online, cross-sectional survey of a diverse group of healthcare providers in the 10 U.S. cities with the greatest HIV prevalence was conducted between July 2014 and May 2015. Participants responded to a patient vignette of a PWID and asked to indicate whether the patient would be a candidate for PrEP and why via free-response text. Descriptive statistics are reported using frequency measures. Bivariate analyses were conducted using chi-squared comparisons and logistical regression.
Results:
Survey data from 480 providers were included in analyses. Of the 480 responses, 85.5% were classified as PrEP aware, while 14.2% were PrEP unaware. Additionally, 82.6% indicated the patient would be a good candidate for PrEP, 4.4% believed the patient was not a good candidate for PrEP, and 13% were unsure. Among those who were unsure or would not prescribe PrEP (n = 84), open-ended responses indicated lack of knowledge (42.9%), concern about adherence (27.4%), concern about cost (4.8%), and bias (7.1%) as the primary reasons.
Conclusions:
Although the majority of providers in this study did not demonstrate bias against PWID, our study found that limited PrEP knowledge and bias are barriers to PrEP prescription among PWID for some providers. Interventions are needed that increase PrEP awareness of CDC guidelines and reduce implicit bias among providers.

HIV disproportionately affects sexual minority men (SMM) in the United States.
We sought to determine past HIV postexposure prophylaxis (PEP) use and current and prior pre-exposure prophylaxis (PrEP) use among a web-based sample of cisgender and transgender men who have sex with men.
In 2019, HIV-negative and unknown status SMM (n=63,015) were recruited via geosocial networking apps, social media, and other web-based venues to participate in a brief eligibility screening survey. Individuals were asked about past PEP use and current and prior PrEP use. We examined associations of demographics, socioeconomic indicators, and recent club drug use with PEP and PrEP use, as well as the association between past PEP use and current and prior PrEP use using generalized linear models and multinomial logistic regression. Statistical significance was considered at P<.001, given the large sample size; 99.9% CIs are reported.
Prior PEP use was reported by 11.28% (7108/63,015) of the participants, with current or prior PrEP use reported by 21.95% (13,832/63,015) and 8.12% (5118/63,015), respectively. Nearly half (3268/7108, 46%) of the past PEP users were current PrEP users, and another 39.9% (2836/7108) of the participants who reported past PEP use also reported prior PrEP use. In multivariable analysis, past PEP use was associated with current (relative risk ratio [RRR] 23.53, 99.9% CI 14.03-39.46) and prior PrEP use (RRR 52.14, 99.9% CI 29.39-92.50). Compared with White men, Black men had higher prevalence of past PEP use and current PrEP use, Latino men had higher prevalence of PEP use but no significant difference in PrEP use, and those identifying as another race or ethnicity reported higher prevalence of past PEP use and lower current PrEP use. Past PEP use and current PrEP use were highest in the Northeast, with participants in the Midwest and South reporting significantly lower PEP and PrEP use. A significant interaction of Black race by past PEP use with current PrEP use was found (RRR 0.57, 99.9% CI 0.37-0.87), indicating that Black men who previously used PEP were less likely to report current PrEP use. Participants who reported recent club drug use were significantly more likely to report past PEP use and current or prior PrEP use than those without recent club drug use.
PrEP use continues to be the predominant HIV prevention strategy for SMM compared with PEP use. Higher rates of past PEP use and current PrEP use among Black SMM are noteworthy, given the disproportionate burden of HIV. Nonetheless, understanding why Black men who previously used PEP are less likely to report current PrEP use is an important avenue for future research.
