RESUMEN

Social network strategy (SNS) testing uses network connections to refer individuals at high risk to HIV testing services (HTS). In Tanzania, SNS testing is offered in communities and health facilities. In communities, SNS testing targets key and vulnerable populations (KVP), while in health facilities it complements index testing by reaching unelicited index contacts. Routine data were used to assess performance and trends over time in PEPFAR-supported sites between October 2021 and March 2023. Key indicators included SNS social contacts tested, and new HIV-positives individuals identified. Descriptive and statistical analysis were conducted. Univariable and multivariable analysis were applied, and variables with P-values <0.2 at univariable analysis were considered for multivariable analysis. Overall, 121,739 SNS contacts were tested, and 7731 (6.4%) previously undiagnosed individuals living with HIV were identified. Tested contacts and identified HIV-positives were mostly aged ≥15 years (>99.7%) and females (80.6% of tests, 79.4% of HIV-positives). Most SNS contacts were tested (78,363; 64.7%) and diagnosed (6376; 82.5%) in communities. SNS tests and HIV-positives grew 11.5 and 6.1-fold respectively, from October-December 2021 to January-March 2023, with majority of clients reached in communities vs. facilities (78,763 vs. 42,976). These results indicate that SNS testing is a promising HIV case-finding approach in Tanzania.

RESUMEN

In Kenya, HIV prevalence estimates among female sex workers (FSWs) are almost five times higher than among women in the general population. However, only 68% of infected FSWs are aware of their HIV-positive status. We aimed to identify perceived benefits, opportunities, and barriers of HIV self-testing (HIVST) in improving testing coverage among FSWs. Twenty focus group discussions were conducted with 77 service providers, 42 peer educators (PEs) and outreach workers, and 37 FSWs attending drop-in centers (DiCEs) in four regions of Kenya. An additional 8 FSWs with HIV-negative or unknown status-completed in-depth interviews. Data were analyzed thematically. Acceptability of HIVST was high, with cited benefits including confidentiality, convenience, and ease of use. Barriers included absence of counseling, potential for inaccurate results, fear of partner reaction, possible misuse, and fear that HIVST could lead to further stigmatization. PEs and DiCEs were the preferred models for distributing HIVST kits. FSWs wanted kits made available free or at a nominal cost (100 Kenya Shillings or ∼USD 1). Linkage to confirmatory testing, the efficiency of distributing HIVST kits using peers and DiCEs, and the types and content of effective HIVST messaging require further research.

RESUMEN

Oral pre-exposure prophylaxis (PrEP) is recommended for persons at substantial risk for HIV, including female sex workers (FSW), men who have sex with men (MSM), people who inject drugs (PWID), and transgender women (TGW). We report on a PrEP demonstration project at seven clinics in the Democratic Republic of the Congo. Routinely collected data were abstracted to assess PrEP uptake, scheduled visit attendance, and self-reported adherence. Between February and May 2018, 469 eligible clients were offered daily oral PrEP; 75.1% accepted: 78.7% FSW, 20.5% MSM, and 0.9% TGW. Two percent also identified as PWID. Attendance was 64.5% at one-month visits; 82.1% at three-month visits; and among 47.7% of clients who initiated PrEP at least six months before data abstraction, 85.8% at six-month visits. Among 66.3% of clients with at least one adherence assessment, 39% self-reported low adherence. Results demonstrate the acceptability of PrEP delivered in healthcare settings serving FSW, MSM, PWID, and TGW.

RESUMEN

The U.S. President's Emergency Plan for AIDS Relief (PEPFAR), the largest bilateral funder of human immunodeficiency virus (HIV) prevention and control programs worldwide, currently supports implementation of preexposure prophylaxis (PrEP) to reduce HIV incidence among persons at substantial risk for infection, including female sex workers, men who have sex with men (MSM), and transgender women (hereafter referred to as key populations). Recent estimates suggest that 54% of all global new HIV infections in 2018 occurred among key populations and their sexual partners (1). In 2016, PEPFAR began tracking initiation of PrEP by key populations and other groups at high risk (2). The implementation and scale-up of PrEP programs across 35 PEPFAR-supported country or regional programs* was assessed by determining the number of programs reporting any new PrEP clients during each quarter from October 2016 to September 2018. As of September 2018, only 15 (43%) PEPFAR-supported country or regional programs had implemented PrEP programs; however, client volume increased by 3,351% over the assessment period in 15 country or regional programs. Scale-up of PrEP among general population clients (5,255%) was nearly three times that of key population clients (1,880%). Among key populations, the largest increase (3,518%) occurred among MSM. Factors that helped drive the success of these PrEP early adopter programs included initiation of national, regional, and multilateral stakeholder meetings; engagement of ministries of health and community advocates; revision of HIV treatment guidelines to include PrEP; training for HIV service providers; and establishment of drug procurement policies. These best practices can help facilitate PrEP implementation, particularly among key populations, in other country or regional programs to reduce global incidence of HIV infection.

RESUMEN

Between October 2015 and March 2018, we conducted the Modified Antiretroviral Treatment Access Study (MARTAS), a nurse-delivered case management intervention to improve linkage-to-care for persons recently tested HIV positive. Adult participants from nine urban clinics in three regions of Ukraine were randomized to either MARTAS or standard of care (SOC) using individual, parallel, two-arm design. The main study outcome was linkage-to-care (defined as registration at an HIV clinic) within a 3-month period from enrollment in the study. Intention-to-treat analysis of MARTAS (n = 135) versus SOC (n = 139) showed intervention efficacy in linkage to HIV care (84.4% vs. 33.8%; adjusted RR 2.45; 95% CI 1.72, 3.47; p < 0.001). MARTAS is recommended for implementation in Ukraine and may be helpful in other countries with similar gaps in linkage-to-care. Clinicaltrials.gov registration number: NCT02338024.

RESUMEN

As countries strive to eliminate mother-to-child transmission of HIV, female sex workers (FSW) and their children still face barriers to accessing these essential services. Data on FSW uptake of HIV and reproductive health services before, during, and after pregnancy reveal inadequate service utilization. Stigma encountered by FSW in healthcare settings may contribute to low uptake of HIV testing, antiretroviral therapy (ART), and other prevention of mother-to-child HIV transmission (PMTCT) services. Coordination between community-based FSW and facility-based PMTCT programs can facilitate successful linkage of pregnant FSW to antenatal services to support PMTCT efforts. We offer a way forward to reach 90-90-90 targets for FSW and their families and eliminate mother-to-child transmission of HIV.

RESUMEN

BACKGROUND: Approximately 30% of people living with HIV worldwide are estimated to be unaware of their infection. HIV self-testing (HIVST) is a strategy recommended by the World Health Organization to increase access to and uptake of testing among key populations who are at high risk for HIV infection. OBJECTIVE: This study aimed to describe the development and feasibility of a free, anonymous, internet-based HIVST strategy designed for men who have sex with men in Curitiba, Brazil (electronic testing [e-testing]). METHODS: The project was developed under the scope of the "A Hora é Agora" (The Time is Now) program. Individuals aiming to request an HIVST package (two tests each) answered an anonymous 5-minute questionnaire regarding inclusion criteria and sexual risk behavior. Eligible individuals could receive one package every 6 months for free. Website analytics, response to online questionnaires, package distribution, and return of test results were monitored via a platform-integrated system. RESULTS: Between February 2015 and January 2016, the website documented 17,786 unique visitors and 3218 completed online questionnaires. Most individuals self-reported being white (77.0%), young (median age: 25 years, interquartile range: 22-31 years), educated (87.3% completed secondary education or more), and previously tested for HIV (62.5%). Overall, 2526 HIVST packages were delivered; of those, 542 (21.4%) reported a result online or by mail (23 reactive and 11 invalid). During the study period, 37 individuals who reported using e-testing visited the prespecified health facility for confirmatory testing (30 positive, 7 negative). CONCLUSIONS: E-testing proved highly feasible and acceptable in this study, thus supporting scale-up to additional centers for men who have sex with men in Brazil.

RESUMEN

BACKGROUND: Engagement with HIV medical care is critical to successful HIV treatment and prevention efforts. However, in Ukraine, delays in the timely initiation of HIV treatment hamper viral suppression. By January 01, 2016, only 126,604 (57.5%) of the estimated 220,000 people living with HIV (PLWH) had registered for HIV care, and most (55.1%) of those who registered for HIV care in 2015 did that at a late stage of infection. In the US, Anti-Retroviral Treatment and Access to Services (ARTAS) intervention successfully linked newly diagnosed PLWH to HIV services using strengths-based case management with a linkage coordinator. To tailor the ARTAS intervention for Ukraine, we conducted a qualitative study with patients and providers to understand barriers and facilitators that influence linkage to HIV care. METHODS: During September-October 2014, we conducted 20 in-depth interviews with HIV-positive patients and two focus groups with physicians in infectious disease, sexually transmitted infection (STI), and addiction clinics in Dnipropetrovsk Region of Ukraine. Interviews and focus groups were audio-recorded and transcribed verbatim. We translated illustrative quotes into English. We used thematic analysis for the data analysis. RESULTS: Participants (20 patients and 14 physicians) identified multiple, mostly individual-level factors influencing HIV care initiation. Key barriers included lack of HIV knowledge, non-acceptance of HIV diagnosis, fear of HIV disclosure, lack of psychological support from health providers, and HIV stigma in community. Responsibility for one's health, health deterioration, and supportive provider communication were reported as facilitators to linkage to care. Expected benefits from the case management intervention included psychological support, HIV education, and help with navigating the segmented health system. CONCLUSIONS: The findings from the study will be used to optimize the ARTAS for the Ukrainian context. Our findings can also support future linkage-to-care strategies in other countries of Eastern Europe and Central Asia.

RESUMEN

PURPOSE: Respondent-driven sampling (RDS) was used to recruit four samples of Black and Latino men who have sex with men (MSM) in three metropolitan areas to measure HIV prevalence and sexual and drug use behaviors. We compared demographic and behavioral risk characteristics of participants across sites, assessed the extent to which the RDS statistical adjustment procedure provides estimates that differ from the crude results, and summarized our experiences using RDS. METHODS: From June 2005 to March 2006 a total of 2,235 MSM were recruited and interviewed: 614 Black MSM and 516 Latino MSM in New York City, 540 Black MSM in Philadelphia, and 565 Latino MSM in Los Angeles County. Crude point estimates for demographic characteristics, behavioral risk factors and HIV prevalence were calculated for each of the four samples. RDS Analysis Tool was used to obtain population-based estimates of each sampled population's characteristics. RESULTS: RDS adjusted estimates were similar to the crude estimates for each study sample on demographic characteristics such as age, income, education and employment status. Adjusted estimates of the prevalence of risk behaviors were lower than the crude estimates, and for three of the study samples, the adjusted HIV prevalence estimates were lower than the crude estimates. However, even the adjusted HIV prevalence estimates were higher than what has been previously estimated for these groups of MSM in these cities. Each site faced unique circumstances in implementing RDS. CONCLUSIONS: Our experience in using RDS among Black and Latino MSM resulted in diverse recruitment patterns and uncertainties in the estimated HIV prevalence and risk behaviors by study site.

RESUMEN

Men who have sex with men (MSM) bear a disproportionate burden of hepatitis B virus (HBV) infections. We used serologic data from the National HIV Behavioral Surveillance (NHBS) system to determine the prevalence and correlates of HBV infection, immunization, and susceptibility in a sample of Los Angeles County MSM. Approximately 19 % (95 % CI 15-24 %) had serologic evidence of current or past infection, while 35 % (95 % CI 30-40 %) were susceptible. Compared with the youngest age group, MSM ages 40-49 years had a lower prevalence of immunization (aPR 0.28, 95 % CI 0.17-0.45) and a higher prevalence of infection (aPR 8.53, 95 % CI 3.95-18.4) and susceptibility (aPR 2.02, 95 % CI 1.13-3.63). We also observed poor concordance between self-reported and serologic measures of vaccination. Our results indicate the possibility of missed opportunities to vaccinate MSM. Gaps in implementing existing vaccination strategies must be addressed to increase hepatitis B vaccination coverage for MSM, especially in older age groups.

RESUMEN

We assessed factors associated with HIV care among HIV-infected men who have sex with men (MSM). We used 2008 data on MSM from the National HIV Behavioral Surveillance System (NHBS). Venue-based, time-space sampling was used to recruit and interview men in 21 U.S. cities with high AIDS prevalence. Among self-reported HIV-positive MSM, we used generalized estimating equations (clustered on city of interview) to evaluate factors associated with delayed linkage to care (care entry >3 months after diagnosis), not currently receiving care (no visit for HIV care during the 6 months before the study interview), and not being on antiretroviral therapy (ART). Among 8,153 MSM, 882 (11 %) were self-reported HIV-positive. 25 % had delayed linkage, 12 % were not currently receiving care and among those with at least one heath care visit 30 % were not on ART. In multivariate analysis, lower income and testing positive at their first HIV test were associated with delayed linkage. Age 18-29 years, and not having health insurance were associated with not currently receiving care. Among those with at least one health care visit, being age 18-39 years, having private or no health insurance, and stimulant use were associated with not being on ART. These findings can inform efforts to improve engagement in care.

RESUMEN

OBJECTIVES: We investigated whether high gender role conflict (GRC; internal conflict with traditional gender-role stereotypes and an individual's perceived need to comply with these roles) is associated with psychological distress and HIV-related risk behaviors in a sample of African American men who have sex with men and women (MSMW). METHODS: We analyzed baseline data collected from questionnaires completed by 400 MSMW participating in the Men of African American Legacy Empowering Self project in Los Angeles, California, in 2007 to 2010 for associations between participants' GRC and experiences of poor mental health and HIV risk outcomes. RESULTS: MSMW who reported higher levels of GRC than other participants also reported more psychological distress, lower self-esteem, greater internalized homophobia, less HIV knowledge, lower risk reduction skills, less disclosure of same-sex behaviors to others, and more unprotected vaginal or anal intercourse with female partners. CONCLUSIONS: Future research should consider how high GRC affects African American MSMW's lives and identify specific approaches to help alleviate the psychological distress and other negative behavioral outcomes associated with internal conflict caused by rigid gender role socialization.

RESUMEN

We analyzed HIV surveillance data on white, black, and Latino males diagnosed with HIV between 2000 and 2004 in Los Angeles County (LAC) to identify associations between individual- and community-level factors and late HIV detection by race/ethnicity. We defined late HIV detection as an AIDS diagnosis within 6 months of HIV diagnosis. We conducted multilevel analysis to determine individual- and community-level risk factors associated with late HIV detection stratified by race/ethnicity. We mapped HIV-positive males with late HIV detection by race/ethnicity at the zip code level within LAC to determine high burden areas. Overall, 38% of all males met the definition of late HIV detection. By race/ethnicity, 44% of Latinos, 38% of blacks, and 30% of whites were detected late in their course of HIV infection. Latinos and whites had multiple individual-level risk factors associated with late HIV detection. Among black males, only older age at HIV diagnosis was associated with late HIV detection. The only community-level risk factor associated with late HIV detection was among Latinos living in communities with less than 6% of men who have sex with men (proxy for stigma). Mapping the distribution of late HIV detection showed late detection areas generalized across LAC for Latino males in comparison with white and black males whose maps showed clustered areas of late HIV detection. Analysis and mapping of individual- and community-level risk factors associated with late HIV detection provides an important tool for targeting prevention resources to areas and populations with the highest burden of disease.

RESUMEN

Key populations (KP) in the Democratic Republic of the Congo (DRC), including female sex workers (SW), are disproportionally affected by HIV. Quantitative feedback surveys were conducted at seven health facilities in DRC with 70 KP clients enrolled in pre-exposure prophylaxis (PrEP) services to measure benefits and concerns. The surveys also assessed satisfaction with PrEP services and experiences of stigma at the health facilities. Thirty healthcare workers (HCW) were surveyed to measure attitudes, beliefs, and acceptability of providing services to KP. KP client survey participants were primarily female SW. KP clients reported that the primary concern about taking PrEP was fear of side effects (67%) although few KP reported having experienced side effect (14%). HCW concurred with clients that experienced and anticipated side effects were a primary PrEP uptake concern, along with costs of clinic visits.

RESUMEN

BACKGROUND: During 2003-2005, the National HIV Behavioral Surveillance System (NHBS) enrolled men who have sex with men (MSM) from 12 different venue types in 15 metropolitan areas in the United States. Our goal was to examine whether limiting NHBS enrollment venues to gay bars and dance clubs could increase efficiency without changing the overall results and conclusions. METHODS: We used logistic regression analysis to compare the demographic characteristics and reported HIV risk behaviors among MSM enrolled in gay bars and dance clubs with those enrolled in sex venues and those enrolled in other venues. RESULTS: Of the 11,471 eligible men included in the analysis, 6419 (56%) were enrolled at bars and clubs, 481 (4%) at sex venues, and 4571 (40%) at other venues. Compared with men enrolled at bars and clubs, men enrolled at sex venues were more likely to be older, of nonwhite race/ethnicity, bisexual, infrequent gay venue attendees, and to have 10 or more male sex partners in the past 12 months. Men enrolled at other venues were more likely to be older and less likely to use noninjecting drugs in the past 12 months. The absolute differences in these characteristics between men enrolled in bars and clubs and those enrolled in comparison venue categories were small in most instances. CONCLUSIONS: Although the differences in characteristics by venue category were not large in magnitude, there was evidence that restricting NHBS enrollment to bars and clubs would affect national estimates of behavioral risk factors among MSM.

RESUMEN

OBJECTIVES: We examined the impact of social discrimination and financial hardship on unprotected anal intercourse with a male sex partner of serodiscordant or unknown HIV status in the past 3 months among 1081 Latino and 1154 Black men who have sex with men (MSM; n = 2235) residing in Los Angeles County, California; New York, New York; and Philadelphia, Pennsylvania. METHODS: We administered HIV testing and a questionnaire assessing 6 explanatory variables. We combined traditional mediation analysis with the results of a path analysis to simultaneously examine the direct, indirect, and total effects of these variables on the outcome variable. RESULTS: Bivariate analysis showed that homophobia, racism, financial hardship, and lack of social support were associated with unprotected anal intercourse with a serodiscordant or sero-unknown partner. Path analysis determined that these relations were mediated by participation in risky sexual situations and lack of social support. However, paths between the explanatory variable and 2 mediating variables varied by participants' serostatus. CONCLUSIONS: Future prevention research and program designs should specifically address the differential impact of social discrimination and financial hardship on lack of social support and risky sexual situations among Latino and Black MSM.

RESUMEN

Using cross-sectional data collected from 1081 Latino men who have sex with men (MSM) recruited with respondent-driven sampling (RDS) techniques from Los Angeles and New York, we examined the extent to which Latino MSM reported exposure to social discrimination (i.e., experienced both homophobia and racism, homophobia only, racism only, or neither homophobia nor racism). More than 40% of respondents experienced both homophobia and racism in the past 12 months. Los Angeles participants, those with lower income, and those who reported being HIV-positive were more likely to report experiencing both types of social discrimination. Adjusting for potential confounders, men exposed to both homophobia and racism were more likely than men exposed to neither form of discrimination to report unprotected receptive anal intercourse with a casual sex partner (AOR = 1.92, 95% CI, 1.18-3.24) and binge drinking (AOR = 1.42, 95% CI, 1.02-1.98). Our findings suggest the presence of a syndemic of adverse social experiences and call for more intervention research to address both homophobia and racism experienced among Latino MSM in the United States.

We examined the hypothesis that black and Latino men who have sex with men (MSM) who have supportive social relationships with other people are less likely to have unrecognized HIV infection compared with MSM of color who report lower levels of social support. We interviewed 1286 black and Latino MSM without known HIV infection in three metropolitan areas who were recruited using respondent driven sampling. Participants completed a computer-administered questionnaire and were tested for HIV. Unrecognized HIV infection was found in 118 men (9.2%). MSM who scored higher on the supportive relationship index had significantly lower odds of testing HIV-positive in the study. The mediation analysis identified two possible behavioral pathways that may partially explain this association: men who had strong supportive relationships were more likely to have had a test for HIV infection in the past 2 years and less likely to have recently engaged in high-risk sexual behavior. The findings illuminate the protective role of social relationships among MSM of color in our sample.

RESUMEN

OBJECTIVES: The authors examine whether young black and Latino men who have sex with men (MSM) who have older sex partners are more likely than those who do not have older sex partners to have unrecognised HIV infection. The authors examine whether the association stems from (1) increased sexual risk behaviour with male partners of any age, (2) heightened risk of being exposed to HIV infection by older partners or (3) a combination of these two factors. METHODS: The analytical sample consisted of 723 black and Latino MSM, aged 18-35 years, who were HIV negative or of unknown serostatus at study entry. Participants completed a self-administered questionnaire and were tested for HIV infection. Men who reported having a male sex partner who was at least 4 years older than themselves were compared with those who did not. Outcomes included unprotected receptive anal intercourse (URAI) with male partners of any age (past 3 months) and having unrecognised HIV infection. RESULTS: Men with older partners reported a higher prevalence of URAI (AOR = 1.50, 95% CI 1.02 to 2.21). A second model found that men with older partners had increased odds of having unrecognised HIV infection (AOR = 2.51, 95% CI 1.18 to 5.34) after controlling for the number of URAI partners of any age, which remained an independent predictor. CONCLUSIONS: Young black and Latino MSM who had older male sex partners were at increased risk of having unrecognised HIV infection. This heightened risk was associated with sexual risk behaviour with partners of any age as well as possible increased exposure to HIV infection from older partners.

RESUMEN

BACKGROUND: Among men who have sex with men (MSM) in the United States, the influence of HIV/AIDS complacency and beliefs about the efficacy of highly active antiretroviral therapy (HAART) on HIV-infection risk is unknown. METHODS: We analyzed data from a 1998-2000 cross-sectional 6-city survey of 1575 MSM aged 23 to 29 years who had never tested for HIV or had last tested HIV-negative to assess these plausible influences overall and by race/ethnicity. FINDINGS: Measured as strong endorsement for reduced HIV/AIDS concern due to HAART, HIV/AIDS complacency was associated with reporting ≥10 male sex partners (odds ratio [OR], 2.94; 95% confidence interval [CI], 2.12-4.07), unprotected anal intercourse with an HIV-positive or HIV-unknown-status male partner (OR, 2.06; 95% CI, 1.51-2.81), and testing HIV-positive (adjusted OR [AOR], 2.35; 95% CI, 1.38-3.98). Strong endorsement of the belief that HAART mitigates HIV/AIDS severity was more prevalent among black (21.8%) and Hispanic (21.3%) than white (9.6%) MSM (P < 0.001), and was more strongly associated with testing HIV-positive among black (AOR, 4.65; 95% CI, 1.97-10.99) and Hispanic (AOR, 4.12; 95% CI, 1.58-10.70) than white (AOR, 1.62; 95% CI, 0.64-4.11) MSM. CONCLUSIONS: Young MSM who are complacent about HIV/AIDS because of HAART may be more likely to engage in risk behavior and acquire HIV. Programs that target HIV/AIDS complacency as a means to reduce HIV incidence among young MSM should consider that both the prevalence of strong HAART-efficacy beliefs and the effects of these beliefs on HIV-infection risk might differ considerably by race/ethnicity.
