High Risk For HIV Infection Research Articles

A community-based study of intention to use HIV self-testing among young people in urban areas of southern Ethiopia

In sub-Saharan Africa, young people are at high risk of HIV infection, representing nearly 4 out of 5 new infections. HIV self-testing (HIVST), a new and proactive testing scheme that involves self-collection of a specimen and interpretation of results, is deemed potentially helpful for increasing testing amongst population groups like young people who do not frequently use routine testing services. This study assessed young people’s intention to use HIVST in urban areas of southern Ethiopia drawing on the Theory of Planned Behaviour. A community-based cross-sectional study was conducted with 634 participants aged 15–24 years from six town administrations of two zones in January to February 2023. The participation rate was 634/636 yielding 99.7%. The OraQuick HIVST kit was demonstrated to young people recruited in a door-to-door survey with a face-to-face interview using an electronic questionnaire in a mobile phone-based application. Intention to use HIVST was measured from a 6-point Likert scale with scores of agreements ranging from 1 to 6. Descriptive statistics and ordinal logistic regression analysis were done using STATA version 18. Most of the participants agreed that they would use HIVST if it was available (86.3% agreeing or strongly agreeing). Interestingly, young people who perceived themselves at some to high risk were 0.51 times less likely to be in the higher order of intention to use when HIVST is available to them than those who perceived themselves at no to low risk. Intention to use HIVST increased by a factor of 1.29, 1.84 and 2.35 for every one-unit increase on the mean favourable attitude, perceived behavioural control, and acceptability scores, respectively. The majority of young people intended to use HIVST. Young people’s perceived behavioural control, and acceptability of HIVST affected their intention to use. Intention and subsequent use of HIVST can be enhanced through an understanding of the role of risk perception and positive attitude, confidence to perform and acceptance of the test. Implementation studies are required to examine the actual uptake of HIVST among young people.

Substance Use and Discrimination in a Sample of U.S.-Based Latinx Sexual Minority Men and Their Main Partners.

Substance use, including drug and alcohol misuse, is associated with myriad health conditions, including a higher risk for HIV infection. Although preliminary evidence suggests that higher levels of relationship functioning can buffer against the deleterious health consequences of discrimination on mental health broadly, such protective associations have been understudied with respect to alcohol and drug use. The topic is particularly understudied among Latino sexual minority men even though they are at greater risk for problematic substance use behaviors and are likely to experience multiple forms of discrimination (e.g., racism, homophobia). To address this gap in the literature, we sampled 95 predominantly Latino sexual minority male couples to assess their drinking and drug use behaviors, relationship functioning, and experiences of discrimination. We used Actor-Partner Interdependence models to test our hypotheses. We found that having a partner who experienced discrimination and higher partner reports of relationship functioning buffered against the negative relationship between own experiences of discrimination and drug use, but not problematic drinking. Our results suggest that higher relationship functioning serves as a buffer between the negative ramifications of discrimination on drug use, but not problematic drinking. We explicate implications for policy and practice to facilitate well-being among coupled Latino sexual minority men.

Low Level of Accurate Knowledge of Undetectable Equals Untransmittable (U = U) Among Men Who Have Sex with Men (MSM) Challenges U = U Achievement in Chengdu, Southwestern China.

The introduction of the undetectable equals untransmittable (U = U) statement significantly reduces HIV stigma and provides an empirical basis for achieving "zero transmission." U = U messaging has gained increasing support and is well-developed in several countries. However, the current status of accurate knowledge of U = U and its associated factors among men who have sex with men (MSM) in China remians unclear. We conducted a cross-sectional survey among MSM recruited in Chengdu, China, from March to May 2022 to investigate the percentage of those who knew U = U accurately and to explore associations between sexual risk behaviors, HIV testing, socio-behavioral measures, and accurate knowledge of U = U. Of 497 MSM included in our study, 23.4% (116/497) had accurate knowledge of U = U. More than half of the participants (63.2%, 314/497) reported multiple sexual partnerships, 15.7% (78/497) used substance during sex, 37.4% (186/497) reported inconsistent condom use, and 76.1% (378/497) took HIV testing in the past six months. Factors associated with accurate knowledge of U = U among MSM included substance use during sex (multivariate odds ratios ORm = 1.96; 95%CI: 1.13-3.41), HIV status tested in the last six months (ORm = 2.07; 95%CI: 1.14-3.77), HIV-related literacy (ORm = 1.41; 95%CI: 1.14-1.74) and perceived higher risk of HIV infection (ORm = 1.11; 95%CI: 1.02-1.21). The findings indicate that great challenges need to be conquered for U = U achievement among the MSM population in Chengdu, China. Intervention strategies should be prioritized in health education on high-risk behaviors such as group sex and substance use, information provision and counseling of U = U in HIV testing services, and encouraging U = U knowledge sharing among MSM with their partners in China.

Assessing Consistency of Respondent-driven Sampling Estimators by Using Repeated Surveys among People Who Inject Drugs (PWID) in New Jersey.

Respondent-driven sampling (RDS) is widely used to sample populations with higher risk of HIV infection for whom no sampling frames exist. However, few studies have been done to assess the consistency of RDS estimators in real world settings. We conducted an assessment study on the consistency of RDS estimators using data from the National HIV Behavioral Surveillance - People Who Inject Drugs surveys in Newark, New Jersey from 2005 to 2018. Population parameter estimates based on RDS-I, RDS-II, Gile's SS, and HCG were compared longitudinally and cross-sectionally. Population homophily statistics and differential recruitment statistics were estimated and compared. Convergence plots were used for RDS diagnosis. Sensitivity analyses were conducted on population size estimates and seeds biases. By comparing time-insensitive population parameters and population homophily statistics estimated by four RDS estimators, the study found that RDS-II and Gile's SS could provide longitudinally and cross-sectionally consistent estimates and population homophily statistics on gender and sexual orientation. Cross-sectional comparison of time-sensitive population parameter estimates also supported the consistency of RDS-II and Gile's SS. However, RDS-I and HCG did not perform well in those comparisons. In conclusion, RDS estimators may not address all inconsistencies, but RDS-II and Gile's SS are recommended to weight RDS samples given enough consistency was observed in them.

Adherence and Compliance with Oral Pre-Exposure Prophylaxis (PrEP) for HIV Prevention

Introduction: Men who have sex with men (MSM), transgender people, sex workers, people who inject drugs, individuals in prisons and other closed settings have been considered key populations because they are at high risk of contracting HIV. The World Health Organization (WHO) has recommended Oral Pre-Exposure Prophylaxis (PrEP) because of its protective effect against HIV in this population. This study aims to analyze the factors that influence adherence and compliance with oral PrEP for HIV prevention. Methods: This systematic review was conducted the databases used were the PubMed, CINAHL Complete, and EMBASE. For search keywords, MeSH, CINAHL Subjects, and Emtree terms were combined with AND and OR Boolean operators. Studies selected encompassed quantitative, qualitative, mixed, and multimethod designs, between from 2015 to 2022, in English, Spanish, and Portuguese language. All references were imported and exported through EndNote for data collection. Methodological quality was evaluated using the MMAT checklist. We used deductive thematic analysis based on Taylor there are six categories that influence adherence and compliance to oral PrEP. Results: Out of 526 articles retrieved, 314 duplicates were eliminated and 26 were incorporated. Various factors affect adherence and compliance with oral PrEP. Conclusions: Based on the findings, PrEP's effectiveness and the perceived high risk of HIV infection served as motivators for PrEP utilization, while negative sentiments regarding PrEP, side effects, and stigma acted as hurdles to its use. Readiness facilitated PrEP adoption. Healthcare team support was viewed as an effective attribute for those administering oral PrEP.

Epidemiology of Chlamydia trachomatis and Repeat Positivity Following Detection in New York State.

In New York State, excluding New York City, chlamydia remains a persistent health concern. Our aim was to characterize chlamydia epidemiology and identify groups at higher risk of repeat positivity to inform targeted public health interventions. We analyzed demographic and clinical data of laboratory-confirmed chlamydia cases in New York State from 2015 to 2019. Repeat positivity was defined as a second positive chlamydia test within 31 to 365days of the initial positive test. We compared characteristics of individuals with single and repeat positivity and evaluated associations with repeat positivity using multivariable logistic regression models. During the study period, 176273 individuals were diagnosed with chlamydia, with 17253 experiencing repeat positivity. Repeat positivity was more common among individuals assigned female at birth. Key predictors of repeat positivity among females included non-Hispanic Black (adjusted odds ratio [aOR]: 1.33; 95% confidence interval [CI], 1.27-1.40) race/ethnicity, ages 13 to 19 (aOR: 1.62; 95% CI, 1.55-1.69), prior sexually transmitted infection (STI) diagnosis (aOR: 1.24; 95% CI, 1.18-1.31), symptomatic examination (aOR: 1.07; 95% CI, 1.02-1.13), and county/community (aOR: 1.10; 95% CI, 1.05-1.15) or private/public (aOR: 1.18; 95% CI, 1.11-1.25) provider. Among males, predictors included non-Hispanic Black (aOR: 1.57; 95% CI, 1.45-1.70) race/ethnicity, ages 13 to 19 (aOR: 1.27; 95% CI, 1.17-1.38), HIV coinfection (aOR: 1.30; 95% CI, 1.10-1.54), prior STI diagnosis (aOR: 1.31; 95% CI, 1.20-1.43), extragenital infection site (aOR: 2.59; 95% CI, 2.27-2.95), symptomatic examination (aOR: 1.21; 95% CI, 1.12-1.31), and county/community health (aOR: 1.09; 95% CI, 1.02-1.17) provider. Our findings provide valuable insights for sexual health interventions to prevent chlamydia transmission and recurrence. Prioritizing resources for prevention interventions and tailored sexual health promotion among non-Hispanic Black individuals is crucial. Additionally, targeted STI prevention efforts are needed for males who have sex with men and those initially diagnosed with extragenital infection. Research is warranted on STI prevention among people living with HIV or at high risk of HIV infection. Strengthening prevention strategies through Expedited Partner Therapy and sexual health education for individuals at risk of repeat positivity could enhance prevention efforts.

Predicting the individualized risk of human immunodeficiency virus infection among sexually active women in Ethiopia using a nomogram: prediction model development and validation.

Women are more vulnerable to HIV infection due to biological and socioeconomic reasons. Developing a predictive model for these vulnerable populations to estimate individualized risk for HIV infection is relevant for targeted preventive interventions. The objective of the study was to develop and validate a risk prediction model that allows easy estimations of HIV infection risk among sexually active women in Ethiopia. Data from the 2016 Ethiopian Demographic and Health Survey, which comprised 10,253 representative sexually active women, were used for model development. Variables were selected using the least absolute shrinkage and selection operator (LASSO). Variables selected by LASSO were incorporated into the multivariable mixed-effect logistic regression model. Based on the multivariable model, an easy-to-use nomogram was developed to facilitate its applicability. The performance of the nomogram was evaluated using discrimination and calibration abilities, Brier score, sensitivity, and specificity. Internal validation was carried out using the bootstrapping method. The model selected seven predictors of HIV infection, namely, age, education, marital status, sex of the household head, age at first sex, multiple sexual partners during their lifetime, and residence. The nomogram had a discriminatory power of 89.7% (95% CI: 88.0, 91.5) and a calibration p-value of 0.536. In addition, the sensitivity and specificity of the nomogram were 74.1% (95% CI: 68.4, 79.2) and 80.9% (95% CI: 80.2, 81.7), respectively. The internally validated model had a discriminatory ability of 89.4% (95% CI: 87.7, 91.1) and a calibration p-value of 0.195. Sensitivity and specificity after validation were 72.9% (95% CI: 67.2, 78.2) and 80.1% (95% CI: 79.3, 80.9), respectively. A new prediction model that quantifies the individualized risk of HIV infection has been developed in the form of a nomogram and internally validated. It has very good discriminatory power and good calibration ability. This model can facilitate the identification of sexually active women at high risk of HIV infection for targeted preventive measures.

Identifying patterns of sexual behaviors and PrEP uptake characteristics among MSM who were eligible for PrEP: A national cross-section study

Men who have sex with men (MSM) are at a high risk of HIV infection and should be offered effective preventive measures, such as pre-exposure prophylaxis (PrEP). However, PrEP uptake among eligible MSM was not as high as desired. Diverse research findings on how risky sexual behaviors affect PrEP uptake highlight the necessity for a comprehensive investigation. Understanding the interconnectedness of different sexual behaviors is crucial for evaluating their impact on PrEP uptake among eligible MSM.Using a proportional sampling method, we recruited 5877 MSM aged 16 years and above in mainland China according to PrEP eligibility criteria. Through latent class analysis (LCA), three distinct sexual behavior patterns were identified among eligible MSM. Demographic variances and PrEP uptake among the three distinct sexual behavior patterns were examined using chi-squared tests and multinomial logistic regression.LCA revealed three patterns: low-risk (4,815 MSM), medium-risk (516 MSM), and high-risk (546 MSM). MSM aged 25 years or older with a monthly income of ≥¥8,000 were more likely to be in the medium-risk group. Those from areas with high HIV prevalence and engaging as "top" in anal sex were more likely to be in the medium- and high-risk groups. The medium- and high-risk groups had a higher willingness, uptake, and adherence rates for PrEP than the low-risk group.LCA is effective in identifying diverse sexual behavior patterns among MSM, aiding targeted interventions to enhance PrEP uptake. Addressing demographic variations and tailoring interventions for specific risk groups are crucial for promoting PrEP dissemination and reducing HIV infection risk in eligible MSM.

Preference for novel biomedical HIV pre-exposure prophylaxis methods among adolescent girls and young women in Kampala, Uganda: a mixed methods study

BackgroundNovel HIV pre-exposure prophylaxis (PrEP) methods including a potential future HIV vaccine, will increase prevention options for adolescent girls and young women (AGYW) at high risk of HIV infection in Eastern and Southern Africa, yet data on AGYW’s preferences for various PrEP methods is limited. We investigated preferences for five biomedical PrEP methods (oral, injectable, vaginal ring, implant, HIV vaccine) among 14–24-years-old AGYW in Kampala, Uganda.MethodsFrom January to December 2019, we conducted a mixed methods study including 265 high-risk AGYW. After receiving two education sessions on the five PrEP methods, participants were asked about their “most preferred PrEP method.” Multinomial logistic regression (oral PrEP as reference category) was used to determine participant characteristics associated with method preference. Results are presented as adjusted relative risk ratios (aRRR) with 95% confidence intervals (CI). In-depth interviews were conducted with 20 selected participants to examine reasons influencing PrEP preferences and suggestions for method improvements. Transcripts were analyzed thematically.ResultsParticipants preferred methods were: HIV vaccine (34.7%), oral PrEP (25.7%), injectable PrEP (24.9%), PrEP implant (13.6%), and vaginal ring (1.1%). Preference for injectable PrEP increased with every year of age (aRRR 1.22; 95% CI 1.04–1.44) and among participants with chlamydia or gonorrhoea (aRRR 2.53; 95% CI 1.08–5.90), while it was lower among participants having sexual partner(s) living with HIV or of unknown HIV status (aRRR 0.30; 95% CI 0.10–0.91). Preference for PrEP implants also increased with age (aRRR 1.42; 95% CI 1.14–1.77) and was strong among participants having ≥10 sexual partners in the past 3 months (aRRR 3.14; 95% CI 1.16–8.55), while it was lower among those with sexual partner(s) living with HIV or of unknown HIV status (aRRR 0.25; 95% CI 0.07–0.92). PrEP method preference was influenced by product attributes and prior experiences with similar product forms commonly used in health care.ConclusionAGYW have varied preferences for biomedical PrEP method and those with higher sexual behavioral risk prefer long-acting methods. As we anticipate more available PrEP options, oral PrEP use should be supported among AGYW, especially for those with sexual partners living with HIV or of unknown HIV status.

Assessing reliability of naïve respondent-driven sampling samples by using repeated surveys among people who inject drugs (PWID) in New Jersey

IntroductionRespondent-driven sampling (RDS) is widely used to sample populations with higher risk of HIV infection for whom no sampling frames exist. However, few studies have been done to assess the reliability of RDS in real world settings. MethodsWe assessed the reliability of naïve RDS samples using five rounds of the National HIV Behavioral Surveillance – People Who Inject Drugs surveys in Newark, New Jersey from 2005 to 2018. Specifically, we compared the distributions of time-insensitive demographic characteristics in temporally adjacent RDS samples with Monte Carlo Two-Sample Kolmogorov-Smirnov Test with 100,000 replicates. The distributions of time-sensitive demographic characteristics were also compared as sensitivity analyses. ResultsThe study showed that repeated RDS samples among people who inject drugs in the greater Newark area, New Jersey were reliable in most of time-insensitive demographics and recruitment homophily statistics. Sensitivity analyses of time-sensitive demographics also presented consistencies in most of temporally adjacent samples. ConclusionsIn conclusion, RDS has the potential to provide reliable samples, but demographic characteristics of RDS samples may be easily biased by homophily. Future studies using RDS may need to pay more attention to potential homophily bias and consider necessary diagnostic procedures and sample adjustments.

Main Partner Relationships and the HIV Care Cascade: Examining the Predictive Utility of Sexual Agreements, Partner Concordance, and Drug Use Among Sexual Minority Men Living With HIV in the USA.

The past 15 years have seen increasing attention to relationship factors among sexual minority male (SMM) couples at high risk for HIV infection. Research has largely focused on HIV prevention outcomes. Outcomes relevant to SMM living with HIV have received relatively less attention. This study evaluated associations between relational covariates (relationship status, sexual agreements, and seroconcordance) and HIV care cascade outcomes (having a current antiretroviral therapy [ART] prescription, ART adherence, viral load (VL) testing, and VL detectability) above and beyond cannabis and stimulant drug use. Adult SMM (n = 36,874) living with HIV in the USA were recruited between November 1, 2017 and March 15, 2020 through social networking applications. They completed a cross-sectional survey online. Nonmonogamous SMM with serodiscordant partners were most likely to have an ART prescription. Those with seroconcordant partners (regardless of sexual agreements) were least likely to be adherent. While relational covariates were not associated with VL testing, SMM in nonmonogamous relationships with serodiscordant partners were significantly more likely to have an undetectable VL. Those in monogamous relationships with seroconcordant partners were significantly less likely to have an undetectable VL. SMM with seroconcordant partners and monogamous sexual agreements may experience diminished interpersonal motivation for HIV care engagement. HIV care cascade retention messages that emphasize the prevention of onward transmission may have limited relevance for these SMM. Novel intervention strategies are needed to enhance HIV care outcomes in this population, ideally ones that incorporate attention to drug use.

Feasibility of a Mobile Health Intervention for Providing a Continuum of HIV Services for MSM: Pilot Study of the WeTest Program in 3 Cities in China.

Men who have sex with men (MSM) in China have a high risk for HIV infection but experience suboptimal rates of HIV testing and service engagement due to various social and structural barriers. We developed a mobile health (mHealth) intervention entitled "WeTest-Plus" (WeTest+) as a user-centered "one-stop service" approach for delivering access to comprehensive information about HIV risk, HIV self-testing, behavioral and biomedical prevention, confirmatory testing, treatment, and care. The goal of the current study was to investigate the feasibility of WeTest+ to provide continuous HIV services to high-risk MSM. Participants completed a 3-week pilot test of WeTest+ to examine acceptability, feasibility, and recommendations for improvement. Participants completed a structured online questionnaire and qualitative exit interviews facilitated by project staff. "Click-through" rates were assessed to examine engagement with online content. 28 participants were included, and the average age was 27.6 years (standard deviation = 6.8). Almost all participants (96.4%) remained engaged with the WeTest+ program over a 3-week observational period. The majority (92.9%) self-administered the HIV self-test and submitted their test results through the online platform. Overall click-through rates were high (average 67.9%). Participants provided favorable comments about the quality and relevance of the WeTest+ information content, the engaging style of information presentation, and the user-centered features. This pilot assessment of WeTest+ supports the promise of this program for promoting HIV self-testing and linkage to in-person services for MSM in China. Findings underscore the utility of a user-centered approach to mHealth program design.

Factors associated with HIV pre-exposure prophylaxis use among Asian men who have sex with men in Sydney and Melbourne, Australia: a cross-sectional study

Asian-born MSM are a priority population as Australia aims to end HIV transmission, but they reported additional barriers to access PrEP and other HIV prevention methods. This study investigates factors associated with PrEP use among Asian MSM in Sydney and Melbourne, Australia, to inform strategies to improve PrEP uptake in this population. This was a sub-analysis of a community-based cross-sectional survey conducted from March to June 2021. We recruited participants online in Sydney and Melbourne, Australia. Univariable and multivariable logistic regression analyses were performed to identify the factors associated with PrEP use in the last six months and lifetime. Latent class analyses were used to identify subgroups of Asian MSM sharing similar characteristics related to their risk practices for HIV. Overall, 870 Asian MSM were included: 288 Oceanian-born Asian MSM and 582 Asian-born MSM. Three latent classes were identified: 1) Asian-born MSM who recently arrived in Australia with limited English, were less likely to use PrEP and at higher risk of HIV infection (e.g., had condomless anal sex with a casual sex partner in the last six months) (4.6%); 2) Asian MSM who were at lower risk of HIV infection and less likely to use PrEP (69.3%) and; 3) Asian MSM who were at substantial risk of HIV infection and more likely to use PrEP (26.1%). Compared to Oceanian-born Asian MSM, those who were born in Southeast Asia (adjusted odds ratio (aOR)=0.5, 95% confidence interval (CI) 0.3-0.7) and South Asia (aOR=0.4, 95% CI 0.2-0.8) were less likely to ever use PrEP. Compared to Oceanian-born Asian MSM, those who were born in Southeast Asia (aOR=0.4, 95% CI 0.3-0.7), Northeast Asia (aOR=0.5, 95% CI 0.3-0.8) and South Asia (aOR=0.4, 95% CI 0.2-0.7) were less likely to use PrEP in the last six months. To end HIV transmission in Australia, it will be necessary to develop strategies to improve PrEP access for the significant minority of Asian-born MSM who are at substantial risk of HIV infection.

Management practices in facilities providing HIV services to key populations in Kenya and Malawi: A descriptive analysis of management in community-based organizations.

HIV services for key populations (KP) at higher risk of HIV infection are often delivered by community-based organizations. To achieve HIV epidemic control, countries need to scale up HIV services for KP. Little is known about the management practices of community-based organizations delivering health services. We explored the management practices and facility characteristics of community-based health facilities providing HIV services to key populations as part of the LINKAGES program in Kenya and Malawi. We collected information on management practices from 45 facilities called drop-in centers (DICs) during US Government FY 2019, adapting the World Management Survey to the HIV community-based health service delivery context. We constructed management domain scores for each facility. We then analyzed the statistical correlations between management domains (performance monitoring, people management, financial management, and community engagement) and facility characteristics (e.g., number of staff, organization maturity, service scale) using ordinary least square models. The lowest mean management domain scores were found for people management in Kenya (38.3) and financial management in Malawi (25.7). The highest mean scores in both countries were for performance monitoring (80.9 in Kenya and 82.2 in Malawi). Within each management domain, there was significant variation across DICs, with the widest ranges in scores (0 to 100) observed for financial management and community involvement. The DIC characteristics we considered explained only a small proportion of the variation in management domain scores across DICs. Community-based health facilities providing HIV services to KP can achieve high levels of management in a context where they receive adequate levels of above-facility support and oversight-even if they deliver complex services, rely heavily on temporary workers and community volunteers, and face significant financial constraints. The variation in scores suggests that some facilities may require more above-facility support and oversight than others.

Assessing high-risk sexual practices associated with human immunodeficiency virus infection among young female sex workers in Lubumbashi, Democratic Republic of the Congo: a cross-sectional study

IntroductionYoung female sex workers (YFSWs) face a higher risk of HIV infection compared to older workers, but there is a lack of comprehensive data on their sexual practices and HIV infection risks, which may present unique challenges and vulnerabilities. The study aimed to identify high-risk sexual practices associated with HIV infection among YFSWs in Lubumbashi.MethodsWe conducted an analytical cross-sectional study and used a comprehensive sample of all YFSWs who presented to the HIV/Sexually Transmitted Infections Screening and Treatment Center in Lubumbashi between April 2016 and December 2017. We collected data on socio-demographic characteristics and behavioral risk factors of female sex workers were collected using a structured questionnaire. Using STATA version 16, multivariate logistic regression was fitted and the results were presented as adjusted odds ratios (aORs) with their 95% confidence intervals (95% CIs).ResultsA total of 572 YFSWs were included in the study, 19 of whom were HIV-positive (3.3%; 95% CI: 2.1–5.1%). Participants who were forced to have sex (aOR = 12.2; 95% CI: 3.2–46.4; p < 0.0001), those who did not use condoms systematically (aOR = 4.1; 95% CI: 1.3–13.0; p = 0.018), and those who had anal sex (aOR = 23.8; 95% CI: 6.9–82.4; p < 0.0001) were more likely to be HIV-positive.ConclusionThe study reveals a concerning trend of higher hospital HIV prevalence among YFSWs compared to the general Congolese population. It also highlights a significant link between high-risk sexual practices and HIV infection, highlighting the need for urgent interventions.

Comparing Repeated (Annual) Couples HIV Testing and Counseling to Individual HIV Testing and Counseling Among Male Couples at High Risk of HIV Infection: Protocol for a Randomized Control Trial.

Couples HIV testing and counseling (CHTC) is now a standard of care prevention strategy recommended by the Centers for Disease Control and Prevention for sexual minority men (SMM) in relationships. Despite standard recommendations that couples complete CHTC every 6-12 months, no study has empirically evaluated the effects associated with CHTC retesting. This study aims to understand the benefits associated with continued dyadic engagement in the HIV prevention continuum through routine CHTC retesting, which is of particular importance for emerging-adult SMM in relationships who use drugs. Eligible couples for this CHTC retesting trial must already be enrolled in the 4Us trial, where they completed a CHTC session after their baseline survey. The purpose of the original 4Us trial was to test the efficacy of 2 intervention components for CHTC: a communication skills training video and a substance use module. Couples were eligible for the original 4Us trial if they identified as cisgender male, were in a relationship for 3 months or longer, were aged 17 years or older, and communicated in English. At least 1 partner had to be aged 17-29 years, report HIV negative or unknown serostatus, report use of at least 1 drug (cannabis, cocaine or crack, crystal methamphetamine, ketamine, gamma-hydroxybuterate [GHB], psychedelics, ecstasy, prescription medication misuse, opiates, and nitrates) use, and engage in condomless anal sex (CAS) acts with a casual partner or have a main partner who is nonmonogamous or serodiscordant. Those who complete the 4Us 12-month follow-up and remain in a relationship with the partner they participated in 4Us with are offered the opportunity to participate in this CHTC retesting trial. Those consenting are randomized to either CHTC retesting or individual HIV testing. Follow-up assessments are conducted 3 and 6 months after randomization to evaluate the effects of repeat CHTC on 2 primary outcomes: (1) CAS with a casual partner in the absence of preexposure prophylaxis (PrEP), and (2) CAS with a serodiscordant main partner who is not virally suppressed or concurrent CAS between main and casual partners in the absence of PrEP. The CHTC retesting trial launched in January 2023, and enrollment is ongoing. As of February 2024, the study had enrolled 106 eligible participants (n=53 couples). Findings from this CHTC retesting study will contribute to knowledge about the benefits associated with regular (repeated) CHTC testing versus routine individual HIV testing for SMM in relationships. The results of this trial will inform CHTC retesting guidance. ClinicalTrials.gov NCT05833074; htps://www.clinicaltrials.gov/study/NCT05833074. DERR1-10.2196/53023.

Study protocol of a randomized controlled trial to assess the efficacy of the “PrEPare for Work” intervention to enhance PrEP uptake and optimize adherence for HIV prevention among male sex workers in the U.S.

BackgroundMale sex workers (MSWs), specifically cisgender men who exchange sex for money, goods, drugs, or other items of value with other cisgender men, are at high risk for HIV infection. Compared to men not engaged in sex work, MSWs are more likely to engage in frequent condomless sex with paying and non-paying sexual partners. While MSWs are often included as a subgroup of gay and bisexual men, data show that a large proportion identify as heterosexual; additionally, most MSWs do not identify as “sex workers.” This places MSWs in a unique position where they may not engage with traditional HIV prevention programs, and when they do, they may not feel comfortable, leading to poor retention. Thus, HIV prevention interventions that address MSWs’ unique life circumstances and provide support in exploring their sexual health options are needed.MethodsIn this protocol paper, we describe the design and procedures for a National Institute of Health-funded, randomized controlled trial testing the efficacy of “PrEPare for Work,”— a theory-based, manualized PrEP uptake and adherence intervention for MSW — using a 2-stage randomization design. Stage 1: MSWs are equally randomized to receive either the “PrEPare for Work Stage 1 intervention” (strength-based case management and facilitated PrEP linkage) or Standard of Care (SOC) to evaluate successful PrEP uptake (prescription filled) within two months post-randomization. Stage 2: Those who initiate PrEP are then equally re-randomized to receive either the “PrEPare for Work Stage 2 intervention” (1-on-1 skills training, problem-solving, and motivational interviewing adherence counseling and personalized, daily text message reminders) or SOC to assess adherence (Tenofovir concentrations in hair) over 12 months of follow up. Planned analyses will examine intervention efficacy, specific conceptual mediators, and hypothesized moderators.DiscussionBased on our extensive preliminary research, multi-component, theory-informed interventions targeting this subpopulation of MSWs’ unique life circumstances are urgently needed. In this study, we are evaluating whether “PrEPare for Work” can improve PrEP uptake and adherence among MSWs. If this intervention is efficacious, it would be readily disseminated to diverse community organizations that serve MSWs and possibly other community or clinic-based settings.Trial registrationClinicalTrials.gov number NCT05736614, registered February 8, 2023.

Resilience and associated factors in orphaned and separated adolescents in Kenya: Understanding the relationship with care environment and HIV risks

ABSTRACT Orphans are at higher risk of HIV infection and several important HIV risk factors than non-orphans; however, this may be due to a combination of related social, psychological, and economic factors, as well as care environment, rather than orphan status alone. Understanding these complex relationships may aid policy makers in supporting evidence-based, cost-effective programming for this vulnerable population. This longitudinal study uses a causal effect model to examine, through decomposition, the relationship between care environment and HIV risk factors in orphaned and separated adolescents and youths (OSAY) in Uasin Gishu County, Kenya; considering resilience, social, peer, or family support, volunteering, or having one's material needs met as potential mediators. We analysed survey responses from 1105 OSAY age 10–26 living in Charitable Children's Institutions (CCI) (orphanages) and family-based care settings (FBS). Follow-up time was 7–36 months. Care in CCIs (vs. FBS) was associated with a decreased likelihood of engaging in forced, exchange, and consensual sex. Excess relative risks (ERR) attributable to the indirect pathway, mediation, or interaction were not significant in any model. Care environment was not statistically associated with differences in substance use. Our findings support the direct, unmediated, association between institutional care and HIV risk factors.

Factors associated with viral load testing and viral suppression among HIV-positive female sex workers in Nigeria.

Female sex workers (FSWs) are at high risk for HIV infection and face unique barriers to receiving and adhering to testing and treatment. Early viral suppression and consistent viral load testing are critical to optimizing health and reducing transmission in this population. However, the factors associated with testing and successful viral suppression among FSWs are poorly understood, especially in Sub-Saharan Africa. Our study aimed to examine factors, including social, demographic, and clinical characteristics, associated with viral load testing and suppression among female sex workers initiating antiretroviral therapy in Nigeria. In this retrospective study, we analyzed routine programmatic data from FSWs enrolled in the National HIV Key Populations (KP) program in Nigeria. We included FSWs who were newly diagnosed with HIV and registered between January 2016 and January 2022. Primary outcomes of interest were a), receiving a viral load test at any point after treatment initiation and b), viral suppression (<1000 copies/ml) at the test closest to 6 months after treatment initiation. To identify factors associated with the outcomes of interest, we used univariable and multivariable logistic regression, with random intercepts for care facilities, and multiple imputation for missing values. Out of 34,976 FSWs, 97.1% (n = 33,945) received at least one viral load test, with 94.5% (n = 32,092) indicating viral suppression. The odds of receiving at least one viral load test were higher for those who entered treatment in more recent years, those with formal education and those with advanced HIV stages at baseline (adjusted odds ratios [aOR]: 1.17 [1.14-1.19] for those who entered treatment in 2020 vs. 2016; 1.02 [1.01-1.03] for post-secondary vs. no education; and 1.05 [1.01-1.10] for WHO clinical stage 3/4 vs. stage 1 respectively). The odds of successful viral suppression were higher for those who entered treatment in more recent years, but lower for those with advanced HIV stages at baseline (aOR: 1.13 [1.09-1.18] for 2022 vs. 2016; and 0.92 [0.87-0.98] for WHO clinical stage 3/4 vs. stage 1 respectively). The study underscored the relevance of timely diagnosis and ART initiation for optimal outcomes among HIV-positive FSWs in Nigeria. We also observed significant improvements in the likelihood of early viral load testing and suppression over the study period, reflecting advancements in the KP program. Further research should clarify factors driving these trends to further strengthen the HIV care pipeline for female sex workers.

HIV self-testing: A highly acceptable and feasible strategy for reconnecting street adolescents with HIV screening and prevention services in Togo (The STADOS study).

HIV self-testing is a complementary screening strategy that could facilitate access to HIV care services for street adolescents. The objectives of this study were to assess the acceptability and feasibility of HIV self-testing and their associated factors, to estimate HIV prevalence among street adolescents in Togo, and to describe the sexual behavior of this population. A cross-sectional study was conducted between July 2021 and May 2022 in Lomé and Kara (Togolese cities with the highest number of street adolescents). Street adolescents aged 13-19 years were included. An oral HIV self-test (OraQuick®) was used. Acceptability was defined as the proportion of adolescents who completed the test, and feasibility was defined as the proportion of adolescents who reported a test with a valid result. An HIV serological test was performed for all participants. A weighted logistic regression model was used to identify the factors associated with the acceptability and feasibility of HIV self-testing. A total of 432 street adolescents (12.3% female) with a median age of 15 years, interquartile range (IQR) [14-17], were included in this study. Of the 231 sexually active adolescents, only 30.3% (n = 70) reported having used a condom during their last sexual intercourse. HIV self-test was offered to a sub-sample of 294 street adolescents. Acceptability was 96.6% (284/294), (95%CI = [93.8-98.3]) and feasibility 98.9% (281/284), (95%CI = [97.0-100.0]). Being 16 years of age or older (aOR = 28.84; p<0.001) was associated with HIV self-test acceptability. Reporting drug abuse (aOR = 0.47; p = 0.020) was negatively associated to acceptability. Having an educational level at least equivalent to secondary school was associated to HIV self-testing feasibility (aOR = 3.92; p = 0.040). Self-test results were correctly interpreted by 98.6% of street adolescents. HIV prevalence was estimated at 0.9% (95%CI [0.4-2.4]). HIV self-testing is acceptable and feasible among street adolescents, a population at high risk of HIV infection in Togo. The provision of HIV self-testing kits, coupled with condom distribution, represents an opportunity to improve access to HIV care services.
