RESUMEN

INTRODUCTION: 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 reliability of RDS in real world settings. METHODS: We 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. RESULTS: The 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. CONCLUSIONS: In 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.

RESUMEN

ABSTRACT: Key populations (KPs) experience suboptimal outcomes along the HIV care and prevention continua, but there is limited study of the challenges service providers encounter delivering HIV services to KPs, particularly in settings like Zambia, where provision of these services remains legally ambiguous. Seventy-seven providers completed in-depth interviews exploring constraints to HIV service delivery for KPs and recommendations for improving access and care quality. Thematic analysis identified salient challenges and opportunities to service delivery and quality of care for KPs, spanning interpersonal, institutional, and structural domains. Limited provider training in KP-specific needs was perceived to influence KP disclosure patterns in clinical settings, impeding service quality. The criminalization of KP sexual and drug use behaviors, coupled with perceived institutional and legal ambiguities to providing HIV services to KPs, cultivated unwelcoming service delivery environments for KPs. Findings elucidate opportunities for improving HIV service delivery/quality, from decentralized care to expanded legal protections for KPs and service providers.

RESUMEN

BACKGROUND: HIV pre-exposure prophylaxis (PrEP) persistence and adherence are critical to ending the HIV epidemic in the United States. SETTING: In 2017 National HIV Behavioral Surveillance, HIV-negative men who have sex with men (MSM) in 4 US cities completed a survey, HIV testing, and dried blood spots at recruitment. METHODS: We assessed 3 PrEP outcomes: persistence (self-reported PrEP use at any time in the past 12 months and had tenofovir, emtricitabine, or tenofovir diphosphate detected in dried blood spots), adherence at ≥4 doses/week (self-reported past-month PrEP use and tenofovir diphosphate concentration ≥700 fmol/punch), and adherence at 7 doses/week (self-reported past-month PrEP use and tenofovir diphosphate concentration ≥1250 fmol/punch). Associations with key characteristics were examined using log-linked Poisson regression models with generalized estimating equations. RESULTS: Among 391 MSM who took PrEP in the past year, persistence was 80% and was lower among MSM who were younger, had lower education, and had fewer sex partners. Of 302 MSM who took PrEP in the past month, adherence at ≥4 doses/week was 80% and adherence at 7 doses/week was 66%. Adherence was lower among MSM who were younger, were Black, and had fewer sex partners. CONCLUSIONS: Although persistence and adherence among MSM were high, 1 in 5 past-year PrEP users were not persistent and 1 in 5 past-month PrEP users were not adherent at levels that would effectively protect them from acquiring HIV (ie, ≥4 doses/week). Efforts to support PrEP persistence and adherence should include MSM who are young, are Black, and have less education.

RESUMEN

INTRODUCTION: In 2010, British Columbia (BC) implemented HIV Treatment as Prevention (TasP) as policy. We examined trends in virologic suppression and determinants of significant viremia among a prospective biobehavioural cohort of men who have sex with men (gbMSM) in Vancouver from 2012-2017. METHODS: Respondent-driven sampling was used to recruit sexually active gbMSM (≥16 years) who completed biannual study visits with a computer-assisted self-interview and clinical CD4 and viral load (VL) testing. We linked participant data with the BC HIV Drug Treatment Program to obtain antiretroviral dispensing and VL data. We conducted a trend analysis of VL suppression using univariable generalized estimating equation (GEE) multi-level modelling and multivariable GEE to identify factors associated with episodes of VL ≥200 copies/mL. RESULTS: Of 774 participants, 223 were living with HIV at baseline and 16 were diagnosed during follow-up (n = 239). We observed a significant trend towards reduced levels of unsuppressed VL (>200 copies/mL) from 22% (07/2012-12/2012) to 12% (07/2016-12/2016) (OR:0.87; 95%CI:0.83-0.91 for each 6-month period). Among those with at least one follow-up visit, (n = 178, median follow-up = 3.2 years, median age = 46.9 years), younger age (aOR:0.97; 95%CI:0.94-0.99, per year), ecstasy use (aOR:1.69; 95%CI:1.13-2.53), crystal methamphetamine use (aOR:1.71; 95%CI:1.18-2.48), seeking sex via websites (aOR:1.46; 95%CI:1.01-2.12), and lower HIV treatment optimism (aOR:0.94; 95%CI:0.90-0.97) were associated with episodes of elevated viremia. CONCLUSIONS: During a period when TasP policy was actively promoted, we observed a significant trend towards reduced levels of unsuppressed VL. Continued efforts should promote HIV treatment optimism and engagement, especially among younger gbMSM and those who use ecstasy and crystal methamphetamine.

RESUMEN

Travelers may adapt HIV risk-reduction practices based on perceived destination-specific norms. We examined the association between perceived condom norms and condomless anal sex (CAS) during international and domestic travel and in the home environment among men who have sex with men. Men who traveled internationally in the past 12 months were recruited by respondent-driven sampling (N = 501). Not knowing destination-specific condom norms was significantly associated with less CAS during international travel and in the home environment but not during domestic travel. Perceiving home environment condom norms to expect use of condoms was significantly associated with less CAS during domestic but not international travel. Men were less likely to engage in CAS during international travel when destination-specific condom norms were unknown. Unfamiliarity with the environment and culture may influence some men to refrain from higher-risk behaviors. During domestic travel, some men appeared to apply home environment condom norms, which may be erroneous in some situations and pose an HIV risk.

RESUMEN

Disparities in morbidity and mortality related to COVID-19 based on race and ethnicity have been documented in the USA. However, it is unclear if these disparities also exist at the exposure stage. To determine this, studies are needed to document the underlying burden of disease, potential disparities through serologic surveillance. Additionally, such studies can help identify where along the disease spectrum (e.g., exposure, infection, diagnosis, treatment, death) and with regard to the structural factors that necessitate public health and/or clinical interventions. Our objectives in this study were to estimate the true burden of SARS CoV-2 in the community of Essex County, NJ, an early and hard hit area, to determine the correlates of SARS CoV-2 prevalence and to determine if COVID-19 disparities seen by race/ethnicity were also reflected in SARS CoV-2 burden. We utilized venue-based-sampling (VBS) to sample members of the community in Essex County. Participants completed a short electronic survey and provided finger stick blood samples for testing. We sampled 924 residents of Essex County, New Jersey. Testing conducted in this study identified 83 (9.0%) participants as positive for SARS-CoV-2 antibodies. Importantly, our findings suggest that the true burden of SARS-Cov-2 and the pool of persons potentially spreading the virus are slightly more than six times than that suggested by PCR testing Notably, there were no significant differences in odds of testing positive for SARS CoV-2 antibodies in terms of race/ethnicity where we compared Black and Latinx participants to other race participants. Our study suggests that disparities in COVID-19 outcomes stem from potential upstream issues such as underlying conditions, access to testing, and access to care rather than disparities in exposure to the virus.

RESUMEN

This study assessed the HIV prevalence among MSM in the greater Newark New Jersey area including Essex, Hudson, Morris and Union Counties and examined correlates of HIV infection among those men. By analyzing National HIV Behavioral Surveillance data on MSM from four counties in New Jersey (N = 175), which were collected via a venue-based sampling method in 2017, this study shows that HIV prevalence among all races/ethnicities (12.5-31.9%) and all age groups (15.1-47.8%) were high. Casual sex and unprotected sex with male partners were prevalent among these men, regardless of HIV test results. MSM who were tested HIV positive were more likely to have diagnosed any sexual transmitted diseases in the last 12 months (AOR: 6.7; 95% CI 2.2, 21.3) and less likely to have had alcohol use in the past 12 months (AOR: 0.3; 95% CI 0.1, 0.8). Findings from behavioral surveillance strengthens the response to the HIV epidemic by providing policy makers and care/prevention providers with peer reviewed data to base their decisions on.

RESUMEN

INTRODUCTION: The first exposure to high-risk sexual and drug use behaviors often occurs during the period of youth (15-24 years old). These behaviors increase the risk of HIV infection, especially among young key populations (KP)-men how have sex with men (MSM), female sex workers (FSW), and people who inject drugs (PWID). We describe the characteristics of young KP participants in the first Biobehavioral Surveillance (BBS) surveys conducted in Mozambique and examine their risk behaviors compared to adult KP. METHODS: Respondent-driven sampling (RDS) methodology was used to recruit KP in three major urban areas in Mozambique. RDS-weighted pooled estimates were calculated to estimate the proportion of young KP residing in each survey city. Unweighted pooled estimates of risk behaviors were calculated for each key population group and chi-square analysis assessed differences in proportions between youth (aged less than 24 years old) and older adult KP for each population group. RESULTS: The majority of MSM and FSW participants were young 80.7% (95% CI: 71.5-89.9%) and 71.9% (95% CI: 71.9-79.5%), respectively, although not among PWID (18.2%, 95% CI: 13.2-23.2%). Young KP were single or never married, had a secondary education level or higher, and low employment rates. They reported lower perception of HIV risk (MSM: 72.3% vs 56.7%, p<0.001, FSW: 45.3% vs 24.4%, p<0.001), lower HIV testing uptake (MSM: 67.5% vs 72.3%, p<0.001; FSW: 63.2% vs 80.6%; p<0.001, PWID: 53.3% vs 31.2%; p = 0.001), greater underage sexual debut (MSM: 9.6% vs 4.8%, p<0.001; FSW: 35.2% vs 22.9%, p<0.001), and greater underage initiation of injection drug use (PWID: 31.9% vs 7.0%, p<0.001). Young KP also had lower HIV prevalence compared to older KP: MSM: 3.3% vs 27.0%, p<0.001; FSW: 17.2% vs 53.7%, p<0.001; and PWID: 6.0% vs 55.0%, p<0.001. There was no significant difference in condom use across the populations. CONCLUSION: There is an immediate need for a targeted HIV response for young KP in Mozambique so that they are not left behind. Youth must be engaged in the design and implementation of interventions to ensure that low risk behaviors are sustained as they get older to prevent HIV infection.

RESUMEN

Monitoring the burden and spread of infection with the new coronavirus SARS-CoV-2, whether within small communities or in large geographical settings, is of paramount importance for public health purposes. Serology, which detects the host antibody response to the infection, is the most appropriate tool for this task, since virus-derived markers are most reliably detected during the acute phase of infection. Here we show that our ELISA protocol, which is based on antibody binding to the Receptor Binding Domain (RBD) of the S1 subunit of the viral Spike protein expressed as a novel fusion protein, detects antibody responses to SARS-CoV-2 infection and vaccination. We also show that our ELISA is accurate and versatile. It compares favorably with commercial assays widely used in clinical practice to determine exposure to SARS-CoV-2. Moreover, our protocol accommodates use of various blood- and non-blood-derived biospecimens, such as breast milk, as well as dried blood obtained with microsampling cartridges that are appropriate for remote collection. As a result, our RBD-based ELISA protocols are well suited for seroepidemiology and other large-scale studies requiring parsimonious sample collection outside of healthcare settings.

RESUMEN

In light of recent advances in HIV prevention and treatment, we reviewed the literature to understand how different types of stigma impact HIV risk; access to HIV prevention, care, and treatment services; and related health outcomes among men who have sex with men (MSM) in the US. We conducted a scoping literature review of observational and qualitative studies that examined stigma and HIV-related outcomes among MSM. Our search identified 5794 studies, of which 47 met the eligibility criteria and were included in the final analysis. The review suggests that stigma remains a formidable barrier to engaging in HIV prevention and treatment among both HIV-negative and HIV-positive MSM. Among the studies of HIV-positive MSM, internalized stigma was related to lower levels of treatment engagement. HIV-positive MSM in the Southern part of the US were also more likely to engage in risky sexual behavior. Perceived health care discrimination was negatively associated with PrEP awareness, particularly among HIV-negative Black MSM. Among young MSM of color, intersectional stigma compounded the social structural barriers to PrEP adherence. Findings indicate that stigma reduction interventions should be implemented in diverse MSM communities to address the disproportionate burden of HIV along with critical gap in the care continuum. Further research should examine how individual types of stigma, including intersectional stigma, affect viral suppression and PrEP uptake and adherence, especially among MSM of color.

RESUMEN

INTRODUCTION: A study was conducted in three districts in Hai Phong province, Vietnam to estimate the population size of the Female Sex Workers (FSW) in June-July 2019. METHODS: The procedures included selection of three districts, compilation of a list of accessible venues where FSW congregate, distribution of first unique objects (first capture) and second unique objects (second capture) to FSW in randomly selected venues and implementation of a Mini-Respondent Driven Sampling (mRDS) Survey (third capture). Population size of the FSW was calculated based on the number of FSW in each round, number of FSW 'recaptured' during the second and the third captures. Additionally, personal network size data captured in the mRDS was used to measure the population of FSW within the three districts using Successive Sampling Population Size Estimates (SS-PSE). RESULTS: The total estimated FSWs in the three selected districts, using Three Source Capture-Recapture (3S-CRC) was 958, which is slightly lower than that estimated using SS-PSE - 1192. The 3S-CRC method yielded a provincial estimate of 1911 while the SS-PSE method resulted in a total of 2379 FSW for the province. CONCLUSION: Two techniques produced different PSE at both the district and the province levels and resulted in estimates lower than ones produced using programmatic data. For planning HIV prevention and care service needs among all FSWs, additional studies are needed to estimate the number of sex workers who are not venue-based and use social media platforms to sell services.

RESUMEN

BACKGROUND: People who inject drugs (PWID) lag behind other key populations in HIV care continuum outcomes. The impacts of criminal justice reform and increasing drug treatment access on HIV have been underexplored. METHODS: We developed agent-based models (ABM) of sexual partnerships among PWID and non-PWID, and injection equipment-sharing partnerships among PWID in five US cities (Baltimore, Boston, Miami, New York City, San Francisco) over 3 years. The first set of ABM projected changes in partnership discordance among PWID as a function of decreasing ZIP code-level incarceration rates. The second set projected discordance as a function of increasing ZIP code-level drug treatment access. ABM were parameterized and validated overall, and by city and PWID race/ethnicity (Black, Latino, White) using National HIV Behavioral Surveillance data, administrative ZIP code-level data, surveillance reports and prior literature. Informed by research on prisoner release and community-level HIV prevalence, reductions in incarceration rates were fixed at 5% and 30% and respectively projected to increase ZIP code-level HIV prevalence by 2% and 12%. Increases in drug treatment access were fixed at 30% and 58%. RESULTS: In each city, a 30% reduction in ZIP code-level incarceration rates and 12% increase in ZIP code-level HIV prevalence significantly increased sero-discordance among at least one racial/ethnic group of PWID by 1-3 percentage points. A 5% reduction in incarceration rates, and 30% and 58% increases in drug treatment access, led to isolated significant changes in sero-discordance among Black and White PWID that were less than 1 percentage point. CONCLUSION: Reductions in incarceration rates may lead to short-term increases in sero-discordant partnerships among some PWID by increasing community-level HIV prevalence. Efforts to increase HIV testing, engagement in care and community reintegration post release, should be strengthened in the wake of incarceration reform. Additional research should confirm these findings and explore the lack of widespread impacts of drug treatment in this study.

RESUMEN

BACKGROUND: Beliefs regarding responsibility for preventing HIV transmission may differ between individuals and their sexual partners. We assessed HIV prevention responsibility beliefs among men who have sex with men (MSM) participating in the 2017 National HIV Behavioral Surveillance survey. METHODS: MSM were recruited using time-location sampling at clubs, bars, and street locations in San Francisco. HIV prevention responsibility beliefs were assessed on a four-point scale (1 = strongly disagree to 4 = strongly agree). Associations were assessed using generalizing estimating equations to adjust for behaviors within multiple partnerships. RESULTS: A total of 316 HIV-negative men and 76 HIV-positive men reported on 1336 partnerships. HIV-negative compared with HIV-positive men had higher endorsement of mutual responsibility (mean 3.7 vs. 3.5; P < 0.01). Both groups had similar levels of endorsing responsibility on the HIV-negative or HIV-positive partner. HIV-positive men endorsing equal responsibility were more likely to know their partner's HIV status (P < 0.01) and less likely to have serodiscordant condomless anal intercourse (CAI) (P < 0.01) than men who did not endorse equal responsibility. HIV-negative men in partnerships with pre-exposure prophylaxis (PrEP) use were more likely to know their partner's HIV status (P = 0.02) and have serodiscordant CAI (P = 0.04) than men not in partnerships with PrEP use. CONCLUSIONS: HIV-negative and HIV-positive men accept responsibility for preventing HIV. The finding that HIV-negative men in partnerships with PrEP use who engage in serodiscordant CAI is concerning because they are still at risk for other sexually transmitted infections, which are presently at elevated levels in San Francisco and other US cities.

RESUMEN

BACKGROUND: Mozambique has a generalized HIV epidemic of 13.5% among the general population. Early modeling exercises in Mozambique estimate that key populations (KP), defined as men who have sex with men (MSM), female sex workers (FSW), and people who inject drugs (PWID), along with their partners account for about one third of all new infections. There is limited data describing the engagement of KP living with HIV in testing, care and treatment services. METHODS: We conducted a secondary data analysis of HIV-positive participants in the first Bio-behavioral Surveillance (BBS) surveys in Mozambique conducted 2011-2014 in order to assess service uptake and progress though the HIV treatment cascade among MSM, FSW, and PWID. Unweighted pooled estimates were calculated for each key population group. RESULTS: Among HIV-positive MSM, 63.2% of participants had ever received an HIV test, 8.8% were aware of their status, 6.1% reported having been linked to care, while 3.5% initiated ART and were currently on treatment. Of the HIV-infected FSW participants, 76.5% reported a previous HIV test and 22.4% were previously aware of their status. Linkage to care was reported by 20.1%, while 12.7% reported having initiated ART and 11.8% reported being on treatment at the time of the survey. Among HIV-infected PWID participants, 79.9% had previously received an HIV test, 63.2% were aware of their HIV status, and 49.0% reported being linked to care for their HIV infection. ART initiation was reported by 42.7% of participants, while 29.4% were on ART at the time of the survey. CONCLUSION: Among the three high risk populations in Mozambique, losses occurred throughout critical areas of service uptake with the most alarming breakpoint occurring at knowledge of HIV status. Special attention should be given to increasing HIV testing and linkage to ART treatment. Future surveys will provide the opportunity to monitor improvements across the cascade in line with global targets and should include viral load testing to guarantee a more complete picture of the treatment cascade.

RESUMEN

BACKGROUND: People who use drugs (PWUD) which includes both people who inject drugs (PWID) and non-injection drug users (NIDU) are marginalized, experience high levels of stigma and discrimination, and are likely to have challenges with accessing health services. Mozambique implemented the first drop-in center (DIC) for PWUD in Maputo City in 2018. This analysis aims to assess the prevalence of HIV, viral hepatitis B (HBV) and C (HCV) and tuberculosis (TB) among PWUD, and assess their linkage to care and associated correlates. METHODS: We conducted a cross-sectional retrospective analysis of routine screening data collected from the first visit at the drop-in center (DIC) during the period of May 2018 to November 2019 (18 months). Descriptive and multivariable logistic regression analysis were conducted to estimate adjusted odds ratios (aOR) and 95% confidence intervals (CI) of HIV, HBV, HCV and TB infections among PWID and NIDU. Cox proportional hazards models of determinants were used to estimate time from HIV diagnosis to linkage to care for PWUD. RESULTS: A total of 1,818 PWUD were screened at the DIC, of whom 92.6% were male. The median age was 27 years (range:14-63). Heroin was the most consumed drug (93.8%), and among people who used it, 15.5% injected it. Prevalence of HIV (43.9%), HCV (22.6%) and HBV (5.9%) was higher among PWID (p<0.001). Linkage to HIV care was observed in 40.5% of newly diagnosed PWID. Factors associated with shorter time to linkage to care included drug injection (aHR=1.6) and confirmed TB infection (aHR=2.9). CONCLUSION: This was the first analysis conducted on the implementation of the DIC in Mozambique and highlights the importance of targeted services for this high-risk population. Our analysis confirmed a high prevalence of HIV, HBV and HCV, and highlight the challenges with linkage to care among PWID. The expansion of DIC locations to other high-risk localities to enhance HIV testing, treatment services and linkage to care to reduce ongoing transmission of HIV, HBV, HCV and TB and improve health outcomes.

RESUMEN

High quality, representative data from HIV surveillance systems that have country ownership and commitment are critical for guiding national HIV responses, especially among key and priority populations given their disproportionate role in the transmission of the virus. Between 2011 to 2013, the Mozambique Ministry of Health has conducted five Biobehavioral Surveillance Surveys among key populations (female sex workers, men who has sex with men and people who inject drugs) and priority populations (long distance truck drives and miners) as part of the national HIV surveillance system. We describe the experience of strengthening the HIV surveillance system among those populations through the implementation of these surveys in Mozambique. We document the lessons learned through the impact on coordination and collaboration; workforce development and institutional capacity building; data use and dissemination; advocacy and policy impact; financial sustainability and community impact. Key lessons learned include the importance of multisectoral collaboration, vital role of data to support key populations visibility and advocacy efforts, and institutional capacity building of government agencies and key populations organizations. Given that traditional surveillance methodologies from routine data often do not capture these hidden populations, it will be important to ensure that Biobehavioral Surveillance Surveys are an integral part of ongoing HIV surveillance activities in Mozambique.

RESUMEN

Psychological processes may mediate the relationship between minority stress and mental health though limited data exist showing this pathway among trans women. Trans women's degree of satisfaction with their body is associated with mental health outcomes. This study used a model of minority stress to explore for indirect effects on the association between transphobia-based victimization and anxiety and depression through one's degree of body satisfaction. Analysis also explored for racial differences. Transgender women (N = 233) were recruited in 2013 using respondent-driven sampling. Sociodemographics, transphobia-based victimization experiences such as having been physically abused, body satisfaction, and mental health were measured. Analyses assessed for direct and indirect associations while controlling for gender confirmation therapies (i.e., cross-sex hormone therapy and gender confirmation surgeries) and racial identity; 57% reported depression and 42.1% reported anxiety diagnoses. Participants averaged nearly three of six assessed violence experiences. More than 20% reported low body satisfaction. Contrary to authors' expectations, those reporting African American and Other racial identity experienced less transphobia-based violence than whites. Transphobia-based violence was significantly associated with anxiety, depression, and body satisfaction. Body satisfaction was associated with mental health diagnoses. Bootstrapping revealed significant indirect and total effects. Body satisfaction mediated the relationship between transphobia-based violence and mental health. Clinical intervention that promotes body satisfaction including access to gender confirmation therapies, especially hormone therapy, may prevent negative mental health outcomes among trans women. Individual intervention, however, is not a panacea for structural discrimination. Attention to structural interventions that reduce gender minority stressors including transphobia-based violence is necessary.
