The Influence of Housing Status and Food Insecurity on a Behavioral HIV/STI Prevention Intervention for Black Women under Community Supervision in New York City: A Moderation Analysis.

Black women in community supervision programs (CSPs) are disproportionately affected by HIV and other sexually transmitted infections (STIs). A randomized controlled trial of a group intervention titled Empowering African-American Women on the Road to Health (E-WORTH) demonstrated effectiveness in reducing sexual risk behaviors and STI incidence among Black women in CSPs. This secondary analysis aimed to assess the moderating effects of housing status and food security on E-WORTH effectiveness in reducing sexual risk behaviors and cumulative incidence of STIs over a 12-month period which were found significant in the original trial among a sample of 351 Black women in CSPs in New York City who use drugs and/or engage in binge drinking who reported engaging in HIV risk behaviors or testing positive for HIV. We examined the moderating effects of housing stability, housing independence, and food insecurity on reducing cumulative STI incidence and number of unprotected sex acts using mixed-effects negative binomial regression and logistic regression models that controlled for age, high school education, employment status, and marital status. Findings indicate that the intervention effect was moderated by housing stability, but not housing independence or food security. Compared to the control group, E-WORTH participants who were housing insecure had 63% fewer acts of condomless sex. Our findings highlight the importance of interventions designed for women in CSPs that account for upstream determinants of health and include service linkages to basic needs provisions. Further research is needed to unpack the cumulative impacts of multiple experiences of poverty faced by this population.

Perceptions about doxycycline post-exposure prophylaxis (Doxy-PEP) as an STI-prevention strategy among gay and bisexual men (GBM) in the United States: Results from a qualitative study.

OBJECTIVE: To leverage qualitative data to explore gay and bisexual men's (GBM) perceptions about doxycycline post-exposure prophylaxis (Doxy-PEP). Doxy-PEP is a novel biomedical STI-prevention strategy that helps reduce the risk of acquiring bacterial STIs. Little is known about Doxy-PEP's acceptability in the U.S., nor how best to engage those most vulnerable to STIs in taking up this nascent prevention strategy. METHOD: Between July and September of 2023, 24 GBM from across the U.S. completed qualitative interviews about their perceptions regarding Doxy-PEP. Interviews were analyzed using a codebook approach to thematic analysis. RESULTS: Participants were generally interested in using Doxy-PEP, but were concerned about the potential for antibiotic resistance, side-effects, medication interactions to occur, along with stigmatizing discourse around its use. Meanwhile, participants were motivated by the simplicity of Doxy-PEP and the protection it could confer on both an individual and community-level- as well as its potential to reduce STI-related anxiety. Finally, participants desired additional information on Doxy-PEP to address their concerns. CONCLUSIONS: There is a need for clear guidelines and expanded public health messaging on Doxy-PEP in the U.S.

Preventive and Sexual Health in LGBTQ+ Older Adults.

Sexual health is an important but often overlooked health concern of LGBTQ + older adults. Multiple factors influence sexual health including intersecting identities; adverse life events; coping mechanisms; and psychological, social, and physical health domains. Thus, the use of a culturally competent and comprehensive person-centered approach to sexual health is warranted. In this review, we discuss approaches to engaging LGBTQ + older adults to ensure they are able to achieve their sexual health priorities and prevent new human immunodeficiency virus infections. We also discuss doxycycline postexposure prophylaxis to prevent other sexually transmitted infections and the impact of chemsex.

Impact of a College Sexual Violence Prevention Program on Condom Use: A Mediation Analysis.

College-age students are disproportionately impacted by sexually transmitted infections. Campus programs that reduce sexual violence have received recent investment, are increasingly common, and may offer a platform to increase condom use, but this has not yet been investigated. We explore this novel question through a secondary analysis of a randomized control trial of RealConsent, a web-based, sexual assault program for college women, on three college campuses. By estimating single and multiple-mediator models we examine the relationships between study assignment, the hypothesized mediators: self-efficacy to discuss safer sex, and clarity and assertiveness in sexual communication, and consistent condom use at follow-up. In the single mediator models, self-efficacy for safer sex communication (aOR: 1.11, 95% CI: 1.03-1.19, p = .004), assertiveness in sexual communication (aOR: 1.06, 95% CI: 1.02-1.11, p =.004), and clarity in sexual communication (aOR: 1.03, 95% CI: 1.00-1.05, p = .026) demonstrated significant direct effects on condom use. No statistically significant relationships between RealConsent and the mediators, nor indirect effects were found. In the multimediator model, there were no statistically significant associations identified. Self-efficacy, assertiveness, and clarity in communication about sex may have a positive impact on condom use but we did not find evidence that RealConsent impacted these mediators and thus no mediated effect was identified. Additional research is needed to develop and assess college-based sexual violence prevention programs that include an additional focus on skills specifically related to condom negotiation and use to understand if these widespread programs offer an efficient and effective platform to reduce the impact of sexually transmitted infections (STIs) among this high-risk population.

Efficacy of behavioral interventions to increase engagement in sexual health services among LatinX youth in the United States: A meta-analysis for post-pandemic implications.

INTRODUCTION: LatinX youth in the U.S. are disproportionately affected by HIV and STIs, commonly attributed to a lack of diagnostic testing and regular physician consultations to address sexual health. These disparities have been exacerbated by the COVID-19 pandemic. This meta-analysis seeks to assess the efficacy of behavioral interventions among LatinX youth in the U.S. that aim to increase engagement in sexual health services (i.e., STI/HIV testing, physician consultations). CONTENT: Following PRISMA guidelines, seven electronic databases were searched. We systematically extracted data with a coding form, and effect sizes were obtained from each study on HIV/STI testing outcomes and physician consultation. Moderator analyses were run for demographic and intervention characteristics. SUMMARY AND OUTLOOK: Of nine included studies, the interventions created a small-to-moderate effect on increased engagement of sexual health services (d +=0.204, 95 % CI=0.079, 0.329). Moderator analyses showed that interventions including the following characteristics were most efficacious at facilitating care services: community-based or online setting, access to diagnostic testing, social media/remote components, parental involvement, and longer session duration. This meta-analysis provides informative results regarding behavioral interventions that have proven efficacious in facilitating engagement in sexual health services among LatinX youth. Most prominently, interventions that are remote or through social media, community-based, and incorporated parents had large positive effects. These findings prove useful for the ongoing COVID-19 pandemic situation and provide guidance for targeting LatinX youth to engage them in sexual health services as primary and secondary STI and HIV prevention.

On The Horizon: Novel Approaches to Sexually Transmitted Infection Prevention.

Rates of sexually transmitted infections (STIs), especially cases of infectious and congenital syphilis, are increasing in the United States. Novel strategies for STI prevention are being explored and include doxycycline post-exposure prophylaxis and the potential utility of vaccines against gonorrhea. Self-collection of samples and point of care testing for STI are increasingly being employed in a variety of settings. Both can improve uptake of screening and lead to earlier detection and treatment of incident STI in target populations. Overcoming existing regulatory issues and optimizing implementation of current evidence-based strategies will be key to maximizing future STI prevention efforts. Here we provide an update for primary care providers on selected new strategies for STI prevention either currently available or under development for possible future use.

Implementing High-Intensity, Trauma-Informed Sexual Risk Reduction in Women Involved in the Criminal Legal System.

Although research supports using brief or extended behavioral interventions to increase prevention of sexually transmitted infections (STIs), there is a shortage of current information about the specific effects on women in a short-stay carceral environment. This evidence-based practice implementation project aimed to employ the Safer Sex Efficacy (SSE) Workshop in a jail setting. A repeated measures design was used to compare STI knowledge acquisition and reports of condom use self-efficacy in a group of incarcerated women before, immediately after, and 3 weeks after participation in a high-intensity behavioral counseling intervention. Twenty-one females between the ages of 20 and 45 years participated in the program. STI knowledge acquisition and reports of condom use self-efficacy were measured using the Sexually Transmitted Disease Knowledge Questionnaire and the Condom Use Self-Efficacy Scale. Findings support the feasibility of implementing evidence-based sexual health education programming incorporating information about sexual risk behaviors, STI knowledge, and behavioral skills practice in a short-stay correctional setting and further investigation with a larger sample.

Doxycycline post-exposure prophylaxis for sexually transmitted infections in South Africa.

South Africa has a large burden of bacterial sexually transmitted infections (STIs) with high rates among men who have sex with men (MSM). Randomised controlled trials have recently demonstrated high effectiveness of doxycycline post-exposure prophylaxis (PEP) for prevention of bacterial STIs in MSM, with 70% - 85% reductions in Chlamydia trachomatis infection and syphilis, and approximately 50% reduction in Neisseria gonorrhoeae infection. Doxycycline PEP was not demonstrated to be effective in reducing C. trachomatis and N. gonorrhoeae infection among Kenyan cisgender women. Although no worrisome trends in antimicrobial resistance (AMR) were observed in the trials, important concerns remain about doxycycline PEP and AMR development in STIs, other pathogens, commensals, and the microbiome. Tetracycline resistance in N. gonorrhoeae is already widespread in South Africa, but emergence of AMR in other STIs would be concerning. Larger sample sizes of doxycycline PEP users with longer follow-up time are needed to understand the impact that doxycycline PEP may have on AMR at individual and population level. In this opinion article, we weigh the benefits of doxycycline PEP for prevention of bacterial STIs against the existing AMR concerns and data gaps in the South African context. Based on the current evidence, we conclude that it would be reasonable to offer doxycycline PEP to high-risk MSM on a case-by-case basis, provided that it is offered by experienced sexual health clinicians in settings that have access to diagnostic STI testing and ongoing AMR surveillance.

Potential impact of doxycycline post-exposure prophylaxis prescribing strategies on incidence of bacterial sexually transmitted infections.

BACKGROUND: Doxycycline post-exposure prophylaxis (doxyPEP) reduces bacterial sexually transmitted infection (STI) incidence in people with HIV (PWH) or using HIV preexposure prophylaxis (PrEP). Given concerns about widespread antibiotic use, we identified doxyPEP prescribing strategies to minimize use while maximizing impact on STIs. METHODS: We used electronic health records of gay and bisexual men (GBM), transgender women, and non-binary people assigned male sex at birth with ≥2 STI tests (chlamydia, gonorrhea, syphilis) at an LGBTQ-focused health center during 2015-2020. We defined 10 hypothetical doxyPEP prescribing strategies based on PrEP use, HIV status, or STI history. We estimated doxyPEP use and STI diagnoses averted in counterfactual scenarios in which people meeting prescribing criteria received doxyPEP, assuming STI rates during use would have been reduced by clinical trial efficacy estimates. RESULTS: Among 10,546 individuals (94% GBM), rate of any STI was 35.9/100 person-years. Prescribing doxyPEP to all individuals would have averted 71% of STI diagnoses (number needed to treat for one year to avert one STI diagnosis, NNT = 3.9); prescribing to PrEP users/PWH (52%/12% of individuals) would have averted 60% of STI diagnoses (NNT = 2.9). Prescribing doxyPEP for 12 months after STI diagnosis would have reduced the proportion using doxyPEP to 38% and averted 39% of STI diagnoses (NNT = 2.4). Prescribing after concurrent or repeated STIs would have maximized efficiency (lowest NNTs) but prevented fewer STIs. CONCLUSIONS: Prescribing doxyPEP to individuals with STIs, particularly concurrent or repeated STIs, could avert a substantial proportion of all STI diagnoses. The most efficient prescribing strategies are based on STI history rather than HIV status or PrEP use.

Integration of sexually transmitted infection and HIV pre-exposure prophylaxis services in sub-Saharan Africa: a scoping review.

Background: Persons living in sub-Saharan Africa (SSA) face disproportionate risk from overlapping epidemics of HIV and bacterial sexually transmitted infections (STIs). Pre-exposure prophylaxis (PrEP) for prevention is gradually being scaled up globally including in several settings in SSA, which represents a key opportunity to integrate STI services with HIV pre-exposure prophylaxis (PrEP). However, there is limited literature on how to successfully integrate these services, particularly in the SSA context. Prior studies and reviews on STI and PrEP services have largely focused on high income countries. Methods: We conducted a scoping review of prior studies of integration of STI and PrEP services in SSA. We searched PubMed, EMBASE, Cochrane, and CINAHL, in addition to grey literature to identify studies that were published between January 2012 and December 2022, and which provided STI and PrEP services in SSA, with or without outcomes reported. Citations and abstracts were reviewed by two reviewers for inclusion. Full texts were then retrieved and reviewed in full by two reviewers. Results: Our search strategy yielded 1951 records, of which 250 were retrieved in full. Our final review included 61 reports of 45 studies. Most studies were conducted in Southern (49.2%) and Eastern (24.6%) Africa. Service settings included public health clinics (26.2%), study clinics (23.0%), sexual and reproductive care settings (23.0%), maternal and child health settings (8.2%), community based services (11.5%), and mobile clinics (3.3%). A minority (11.4%) of the studies described only syndromic STI management while most (88.6%) included some form of etiological laboratory STI diagnosis. STI testing frequency ranged from baseline testing only to monthly screening. Types of STI tested for was also variable. Few studies reported outcomes related to implementation of STI services. There were high rates of curable STIs detected by laboratory testing (baseline genitourinary STI rates ranged from 5.6-30.8% for CT, 0.0-11.2% for GC, and 0.4-8.0% for TV). Discussion: Existing studies have implemented a varied range of STI services along with PrEP. This range reflects the lack of specific guidance regarding STI services within PrEP programs. However, there was limited evidence regarding implementation strategies for integration of STI and PrEP services in real world settings.

Drug behaviors, sexually transmitted infection prevention, and sexual consent during chemsex: insights generated in the Budd app after each chemsex session.

Chemsex refers to the intentional use of drugs before or during sex in a specific context, typically involving prolonged sex sessions with multiple partners. Engaging in chemsex is associated with a wide range of health risks and related risk behaviors. We developed a mobile phone application ('Budd-app') to support and inform chemsex participants, reduce potential negative impacts associated with chemsex (e.g., physical, psychological and social health harms), and encourage more reasoned participation. During Budd's development process, 11 participants completed a survey after each chemsex session they attended. This data collection approach provided precise experiences on drug related behavior, prevention measures for sexually transmitted infection and sexual consent on 63 chemsex sessions. The mean duration of chemsex sessions was 17.5 h. Polydrug use was reported during 95% of chemsex sessions with an average of 3.5 agents per session. Unsafe dosing occurred at 49% of chemsex sessions, and 9/11 participants dosed unsafely at least once. Seven participants did not consistently take measures to prevent STI transmission. Nine had experienced peer pressure, both regarding drug use and sexual health. The same number reported sex without consent, not respecting others' boundaries as well as their own boundaries not being respected. Many participants experienced negative impact of their chemsex behavior during (7/9) and after (8/9) chemsex. Through participants' behavior assessment during multiple chemsex sessions, 'within-person' variability can be clarified. This clarification provides valuable insights in personal, emotional and contextual vulnerabilities. These insights can direct an individualized care and support trajectory aimed at addressing those vulnerabilities.

Prevention and health promotion regarding sexually transmitted infections (STI) among university students in Germany.

Aim: University students are sexually active, and the sexual risk behavior of this group is higher than that of the general population. The prevention of sexually transmitted infections (STIs) emphasizes the need for comprehensive knowledge about behaviors for STI protection and the actual realization of these behaviors. Subject and methods: First, an online questionnaire was developed to record the knowledge and realization of STI-protective behaviors among students at Hamburg University of Applied Sciences (HUAS) to conduct quantitative cross-sectional interviews. The sample included 1532 students. Specific aspects of the interview are based on lower response rates. The correlations were then tested by Spearman's rank correlation coefficient and Pearson's chi-squared test. Results: Significant positive correlations were identified between the self-efficacy (SE) and the use of condoms, STI vaccinations, STI tests, and HIV pre-exposure prophylaxis (PrEP). Significant negative correlations were suggested between substance use and the use of condoms and the use of PrEP and the intake of antiretroviral therapy (ART). Significant positive correlations were identified between the knowledge about STI-protective behaviors and the usage of STI-protective vaccinations, STI tests, and ART. Significant positive correlations were identified between the experiences in terms of STIs and the knowledge about STI-protective vaccinations, use of PrEP, and use of ART. Conclusion: Moreover, the results indicate that students with a divergent sexual identity have a higher level of knowledge about STI-protective behaviors. The sexual health of university students should be improved by preventive measures to improve the sexual health of individual students and their social environments.

Exploring What Influences Heterosexual College Men and the Practice of Safe Sex: The Power of Stigma and Community.

The college student population is among the highest risk group for contracting sexually transmitted infections (STIs) such as gonorrhea, chlamydia, and HIV. Safe sex practices, which are intended to mitigate risks associated with sexually transmitted infections, are often negated in the population of heterosexual college students. Historically, research on safe sex practices has shown that the burden of behavior change and the focus on educational efforts historically fall onto the female population. There is little published on how safe sex education for males impacts attitudes and behaviors towards safe sex practices. This community-based participatory research (CBPR) project explored heterosexual college male attitudes and behaviors about safe sex responsibilities with the goal of creating effective health promotion messages to increase safer sex. The research team comprised almost entirely of undergraduate male students, which strengthened the design and translation of results to practice. A mixed methods design was employed utilizing both focus groups and surveys as data collection (n=121). Results showed that young men are still prioritizing pregnancy prevention over disease contraction and/or testing, and relying on female partners to initiate safe sex. Implications for health promotion practice efforts on college campuses include: male-led peer education programming and support and messaging around screening and prevention of STIs.

Mapping LGBTQ+ Youth Resource Density Across Four High HIV Prevalence Corridors in the US.

Introduction: Studies using geospatial data to understand LGBTQ+-friendly sexual health and wellness resource availability have often focused on services catered to adults. While HIV rates have increased in adolescents in recent years, few studies have explored disparities in resource access for adolescent gay and bisexual men (AGBMSM). Methods: We used geospatial data of resources (collected and verified 2017-2018) from the iReach app to understand disparities in resource access for AGBMSM within and between 4 high HIV prevalence corridors in the US. Results: AGBMSM in non-metro areas had access to fewer resources and some rural counties had no LGBTQ+ -friendly resources. Corridors comprising states with legacies of punitive laws targeting sexual and gender minorities demonstrate stark geographic disparities across the US. Conclusions: Policy-makers must understand the granularity of disparities within regions. Online resources may be able to surmount LGBTQ+ resource deserts. However, physical access to LGBTQ+ -friendly services must be improved as a fundamental strategy for reducing HIV among AGBMSM.

The relevance of communal altruism for sexual minority men in contemporary contexts.

There are many reasons why individuals engage in prosocial behavior; communal sexual altruism is based on the notion that some practice safer sex in the interest of promoting the well-being of their community/in-group. Given that definitions of what constitutes "safer sex" have changed with advances in human immunodeficiency virus (HIV) prevention, we investigated the importance of communal sexual altruism (herein "altruism") among urban gay, bisexual, and other sexual minority men (GBM) in the contemporary context. Using a sample of 2449 GBM we examined the association of both safer-sex-related attitudes (e.g., HIV treatment optimism-skepticism) and behaviors (e.g., condomless anal sex [CAS]) with altruism scores. Higher altruism scores were associated with a lower likelihood of CAS and a greater frequency of discussing HIV status with new partners. These findings demonstrate that many GBM are motivated to engage in several kinds of behaviors that improve the well-being of their in-group (i.e., the GBM community).

The Incidence Rate of Sexual Behaviors Among Cisgender Men Who Have Sex with Men Attending a Sexual Health Clinic.

Although nuanced parameterization of sexual behavior may improve estimates from mathematical models of human immunodeficiency virus and sexually transmitted infection transmission, prospective estimates of the incidence of specific sexual behaviors among men who have sex with men (MSM) are limited. From December 2014 to July 2018, MSM with and without nongonococcal urethritis (NGU) completed weekly diaries over 3-12 weeks. Incidence rates of any sex, receptive anal sex, insertive anal sex, insertive oral sex, receptive rimming, and receptive hand-penile contact were 1.19, 0.28, 0.66, 0.90, 0.24, and 0.85 episodes per person-week, respectively, among 104 MSM with NGU at baseline, and 1.33, 0.54, 0.32, 0.95, 0.44, and 0.88 episodes per person-week, respectively, among 25 MSM without NGU at baseline. Most receptive anal sex (NGU + 83%, NGU - 86%) and insertive anal sex (NGU + 85%, NGU - 76%) episodes were condomless. MSM engaged in sex just over once per week, and condom use was infrequent. Insertive oral sex and receptive hand-penile contact were the most common behaviors.

Sexual and Gender Minority Individuals' Interest in Sexual Health Services at Collective Sex Venues in New York City.

Sexual and gender minority individuals who attend collective sex venues (CSVs; establishments where people can have sex in groups or the presence of others) are at elevated risk for HIV and STIs. On-site sexual health interventions have been attempted at CSVs, but attendees' interest in receiving such services is under-investigated. This paper presents results from a 2020 online cross-sectional survey completed by 342 sexual and gender minority individuals who attended CSVs in New York City. Interest in services such as on-site testing for STIs, testing vans near CSVs, and informational referrals was overall high, particularly among younger participants. Among participants who reported being HIV negative, those of younger age and those who were not using PrEP reported being more likely to take an HIV test if it would be offered at CSVs. In open-text survey responses, participants expressed interest in CSVs providing free prevention services such as HIV/STI testing, PEP, PrEP, and STI medications or vaccination, as well as in ways to improve norms surrounding condom use and consent at these venues. Some participants expressed barriers to on-site services such as privacy concerns, preexisting access to health services, an emphasis on personal responsibility, and negative reactions to the presence of service providers. However, some participants also felt that these services could be delivered in a positive, acceptable, and non-judgmental way, especially by involving CSV organizers and attendees in their implementation. Findings from this study can inform future initiatives to develop sexual health interventions at CSVs.

Pre-Exposure Prophylaxis Users' Attitudes About Sexually Transmitted Infections and Its Influence on Condom Use: A Mixed-Method Study in Belgium.

Incidence rates of sexually transmitted infections (STIs) are rising among men who have sex with men (MSM). Since the rollout of HIV pre-exposure prophylaxis (PrEP), promoting condom use to prevent the spread of STIs has become more challenging. Using a mixed-method design, we explored MSM PrEP users' attitudes toward STIs, condoms, and condom use with nonsteady partners to prevent STIs. We triangulated data from 22 in-depth interviews conducted at a large HIV/STI clinic between August 2021 and January 2022 and an online survey among 326 PrEP users between September 2020 and January 2022. Interviews were analyzed iteratively using a thematic analysis approach. We used bivariate and multi-variate ordered logistic regression to analyze the online survey data. Themes identified in the qualitative data influencing condom use decisions to prevent STIs were as follows: (1) awareness (i.e., perceived severity of and susceptibility to STIs, condom counseling), (2) motivation (i.e., concerns about STIs, sexual pleasure and protection of own health), and (3) perceived social norms and practices (e.g., reduced condom use at community level). Overall, 10.7% of survey respondents consistently used condoms with nonsteady partners. Survey respondents who reported high or moderate levels of willingness to use condoms to prevent acquiring STIs were significantly more likely to use condoms for anal sex with nonsteady partners; those who initiated PrEP 6-12 months ago were less likely to use condoms. We found a wide variation in attitudes toward condom use for the prevention of STIs among MSM using PrEP. We recommend client-centered approaches, taking into account PrEP users' values and priorities toward STI prevention to help reduce the spread of STIs.

A savings intervention to reduce men's engagement in HIV risk behaviors: study protocol for a randomized controlled trial.

BACKGROUND: In much of eastern and southern Africa, the incidence of HIV and other sexually transmitted infections (STIs) remains high despite the scale-up of promising biomedical and behavioral interventions. Studies have documented the crucial role of transactional sex-the exchange of money, material support, or goods, in sexual relationships-and heavy alcohol use in contributing to men's and women's health outcomes. Existing policy responses to this challenge have largely focused on women, through the provision of pre-exposure prophylaxis (PrEP) or structural interventions such as education subsidies and cash transfers. However, the effectiveness of these interventions has been hindered by the relative lack of interventions and programs targeting men's behavior. We describe the protocol for a study that will test an economic intervention designed to reduce men's engagement in HIV/STI-related risk behaviors in Kenya. METHODS: We will conduct a randomized controlled trial among income-earning men in Kenya who are aged 18-39 years and self-report alcohol use and engagement in transactional sex. The study will enroll 1500 participants and randomize them to a control group or savings group. The savings group will receive access to a savings account that includes lottery-based incentives to save money regularly, opportunities to develop savings goals/strategies, and text message reminders about their savings goals. The control group will receive basic health education. Over a period of 24 months, we will collect qualitative and quantitative data from participants and a subset of their female partners. Participants will also be tested for HIV and other STIs at baseline, 12, and 24 months. DISCUSSION: The findings from this study have the potential to address a missing element of HIV/STI prevention efforts in sub-Saharan Africa by promoting upstream and forward-looking behavior and reducing the risk of acquiring HIV/STIs in a high HIV/STI burden setting. If this study is effective, it is an innovative approach that could be scaled up and could have great potential for scientific and public health impact in Kenya.
