RESUMEN

The purpose of this study was to demonstrate the effectiveness of HIV self-testing (HIVST) on promoting regular HIV testing, which defined as having uptake HIV testing every three to 6 months, among men who have sex with men (MSM) in Guangzhou, China. 491 ever-tested MSM were recruited from a community-based HIV clinic and randomly assigned into either intervention arm that provided text message plus HIVST service (n = 250) or standard of care arm (n = 241) being a text message promoting HIV testing every 3 months. Overall, 73.7% (330/448) of the participants had uptake HIV testing, and 27.7% (124/448) of them reported ever used of an HIV self-test during study period. HIVST significantly increased regularly HIV testing among participants in the intervention arm compared with standard of care arm (77.4% vs 69.5%). HIVST as a supplement to the existing facility-based testing services is promising in promoting regular HIV testing among MSM in China. Trial registration number: ChiCTR1800016811.

RESUMEN

BACKGROUND: Sexually transmitted infections (STIs) are important public health concerns among black men who have sex with men only (BMSMO), as well as those who have sex with both men and women (BMSMW). Sexually transmitted infections also increase risk of acquiring and HIV, which is also a critical concern. Compared with BMSMO, research shows that BMSMW experience elevated levels of HIV/STI vulnerability factors occurring at the intrapersonal, interpersonal, and social/structural levels. These factors may work independently, increasing one's risk of engaging in high-risk sexual behaviors, but often work in a synergistic and reinforcing manner. The synergism and reinforcement of any combination of these factors are known as a syndemic, which increases HIV/STI risk. METHODS: Data from the HIV Prevention Trials Network (HPTN) 061 study (n = 799) was used to conduct a latent profile analysis to identify unique combinations of risk factors that may form a syndemic and that may vary between BMSMO and BMSMW. We hypothesized that the convergence of syndemic factors would differ between groups and predict sexual risk and subsequent incident STI. RESULTS: For BMSMO who had a high sexual risk profile, the syndemic factors characterizing this group included perceived racism, incarceration, intimate partner violence, depression, and binge drinking. For BMSMW with a high sexual risk profile, the syndemic factors that characterized this group were incarceration, depression, and binge drinking. CONCLUSIONS: The current analysis highlights syndemic profiles that differentiated BMSMO and BMSMW from one another and supports the need for tailored interventions that address specific syndemic factors for both subpopulations of black men who have sex with men.

RESUMEN

We examined sociodemographic and psychosocial factors associated with HIV testing patterns in the past 2 years among 492 HIV-negative men who have sex men (MSM) at an HIV testing center in Guangzhou, China. MSM who tested for HIV frequently were more likely to be older, reside in Guangzhou, and have higher monthly income. Compared with MSM who tested frequently, MSM who never tested were less likely to report that their sexual partner(s) had ever received HIV tests or that their good friends had ever received HIV tests, and were less likely to report having an HIV-positive gay friend or ever discussing HIV with sexual partners; they were more likely to report perceiving barriers to HIV testing. Compared with MSM who tested frequently, those who tested irregularly were less likely to report having HIV-positive gay friends or to disclose their sexual orientation to non-gay friends; reported greater barriers to HIV testing; and higher internalized homophobia.

RESUMEN

Objectives: We sought to test whether discrimination salience and multifactorial discrimination were associated with prevalent experiences of internalized homophobia among middle-aged and older men who have sex with men (MSM).Methods: We analyzed data from 498 middle-aged and older MSM from the Multicenter AIDS Cohort Study (MACS) who reported any lifetime discrimination experience. We estimated the prevalence ratio of current internalized homophobia using multivariable Poisson regressions, accounting for discrimination salience, multifactorial discrimination, and covariates. We then assessed whether multifactorial discrimination moderated the association between discrimination salience and internalized homophobia.Results: Over half (56.4%) of our sample reported any current experience of internalized homophobia. More than two-thirds reported multifactorial discrimination (68.2%) and more than one-third (36.7%) reported moderate-to-high discrimination salience. Increases in discrimination salience (PR = 1.11; 95% CI: 1.03-1.20) were associated with any current internalized homophobia among middle-aged and older MSM. Multifactorial discrimination was not statistically associated with internalized homophobia and did not moderate the association between discrimination salience and internalized homophobia.Conclusions: Our study underscores internalized homophobia as a persisting concern among MSM in midlife and older adulthood. Our findings suggest that salience, as a characteristic of discrimination experiences, may have a greater impact on internalized homophobia compared with exposure. Future research efforts should assess facets of discrimination salience, such as severity, frequency, and chronicity, to better understand how discrimination shapes psychosocial well-being across the life course. Mental health advocates at policy, organizational, and community levels should aim to reduce intersectional stigma and address individual experiences of internalized homophobia.

RESUMEN

Studies suggest that inflammation might be involved in the pathogenesis of depression. Individuals with human immunodeficiency virus (HIV) have a higher risk of depression and elevated inflammatory profiles. Despite this, research on the link between inflammation and depression among this high-risk population is limited. We examined a sample of men who have sex with men from the Multicenter AIDS Cohort Study in prospective analyses of the association between inflammation and clinically relevant depression symptoms, defined as scores >20 on Center for Epidemiological Studies Depression Scale. We included 1,727 participants who contributed 9,287 person-visits from 1984 to 2010 (8,218 with HIV (HIV+) and 1,069 without (HIV-)). Exploratory factor analysis (EFA) was used to characterize underlying inflammatory processes from 19 immune markers. Logistic regression with generalized estimating equations was used to evaluate associations between inflammatory processes and depressive symptoms stratified by HIV serostatus. Three EFA-identified inflammatory processes (EIPs) were identified. EIP-1 scores-described by soluble tumor necrosis factor receptor 2 (sTNF-R2), soluble interleukin-2 receptor α (sIL-2Rα), sCD27, B-cell activating factor, interferon γ-induced protein 10 (IP-10), soluble interleukin-6 receptor (sIL-6R), sCD14, and sGP130-were significantly associated with 9% higher odds of depressive symptoms in HIV+ participants (odds ratio = 1.09; 95% confidence interval: 1.03, 1.16) and 33% higher odds in HIV- participants (odds ratio = 1.33; 95% confidence interval: 1.09, 1.61). Findings suggest that immune activation might be involved in depression risk among both HIV+ and HIV- men who have sex with men.

RESUMEN

Men who have sex with men and women (MSMW), including those who are Black, experience HIV-related disparities compared to men who have sex with men only (MSMO). Few studies have assessed the prevalence and correlates of pre-exposure prophylaxis (PrEP) awareness and use among Black MSMW. We recruited MSM ≥ 18 attending Black Gay Pride events between 2014-2017. We conducted multivariable logistic regressions to assess differences in PrEP awareness and use among HIV-negative Black MSM (n = 2398) and within Black MSMW (n = 419). MSMW were less likely than MSMO to report PrEP awareness (p < 0.001). Among PrEP-aware MSM, MSMW were more likely than MSMO to report PrEP use (p < 0.05). MSMW receiving gay community support were more likely to be PrEP-aware (p < 0.01). MSMW reporting any past-year STI diagnoses were more likely to report PrEP use (p < 0.01). Findings suggest that PrEP awareness campaigns tailored for Black MSMW, concomitant with STI-to-PrEP interventions, will facilitate greater PrEP uptake in this population.

RESUMEN

Social science and public health literature has framed residential segregation as a potent structural determinant of the higher HIV burden among black heterosexuals, but empirical evidence has been limited. The purpose of this study is to test, for the first time, the association between racial segregation and newly diagnosed heterosexually acquired HIV cases among black adults and adolescents in 95 large US metropolitan statistical areas (MSAs) in 2008-2015. We operationalized racial segregation (the main exposure) using Massey and Denton's isolation index for black residents; the outcome was the rate of newly diagnosed HIV cases per 10,000 black adult heterosexuals. We tested the relationship of segregation to this outcome using multilevel multivariate models of longitudinal (2008-2015) MSA-level data, controlling for potential confounders and time. All covariates were lagged by 1 year and centered on baseline values. We preliminarily explored mediation of the focal relationship by inequalities in education, employment, and poverty rates. Segregation was positively associated with the outcome: a one standard deviation decrease in baseline isolation was associated with a 16.2% reduction in the rate of new HIV diagnoses; one standard deviation reduction in isolation over time was associated with 4.6% decrease in the outcome. Exploratory mediation analyses suggest that black/white socioeconomic inequality may mediate the relationship between segregation and HIV. Our study suggests that residential segregation may be a distal determinant of HIV among black heterosexuals. The findings further emphasize the need to address segregation as part of a comprehensive strategy to reduce racial inequities in HIV.

RESUMEN

Compared with Black gay men, Black bisexual men experience psychosocial health disparities, including depression, polydrug use, physical assault, and intimate partner violence (IPV). Black bisexual men are also less likely to disclose their sexuality, which may result in them receiving less sexual minority community support, exacerbating psychosocial health disparities. We assessed relationships between bisexual behavior, bisexual identity, sexuality nondisclosure, gay community support, and psychosocial morbidities among Black men who have sex with men (MSM). Between 2014 and 2017, survey data were collected from Black MSM ≥ 18 years old (n = 4430) at Black Pride events in six U.S. cities. We differentiated between bisexual-identified men reporting past-year sex with men and women (bisexual MSMW, 8.4%); gay-identified men reporting sex with men only (gay MSMO, 73.1%); gay MSMW (8.0%); and bisexual MSMO (8.4%). Multivariable regressions contrasted these groups by psychosocial morbidities, sexuality nondisclosure, and gay community support. Structural equation models assessed total, direct, and indirect effects. Compared with gay MSMO, bisexual MSMW and gay MSMW were significantly more likely to report polydrug use, depression symptoms, IPV, physical assault, sexuality nondisclosure, and lack of gay community support. Lack of gay community support had significant indirect effects on the relationships between bisexual behavior and psychosocial morbidity (p < .001) and between bisexual identity and psychosocial morbidity (p < .001). Sexuality nondisclosure had significant indirect effects on relationships between bisexual behavior (p < .001), bisexual identity (p < .001), and lack of gay community support. Psychosocial health disparities experienced by Black bisexual men are associated with both bisexual behavior and bisexual identity. Interventions decreasing biphobia will facilitate opportunities for protective sexuality disclosure and access to sexual minority community support.

RESUMEN

OBJECTIVES: Center of Epidemiologic Studies-Depression Scale (CES-D) provides a snapshot of symptom severity at a single point in time. However, the best way of using CES-D to classify long-term depression is unclear. METHOD: To identify long-term depression among HIV-infected and HIV-uninfected 50+ year-old men who have sex with men (MSM) with at least 5 years of follow-up, we compared sensitivities and specificities of CES-D-based metrics (baseline CES-D; four consecutive CES-Ds; group-based trajectory models) thresholded at 16 and 20 to a clinician's evaluation of depression phenotype based on all available data including CES-D history, depression treatment history, drug use history, HIV disease factors, and demographic characteristics. RESULTS: A positive depressive phenotype prevalence was common among HIV-infected (prevalence = 33.1%) and HIV-uninfected MSM (prevalence = 23.2%). Compared to the depressive phenotype, trajectory models of CES-D≥20 provided highest specificities among HIV-infected (specificity = 99.9%, 95% Confidence Interval [CI]:99.4%-100.0%) and HIV-uninfected MSM (specificity = 99.0%, 95% CI:97.4%-99.7%). Highest sensitivities resulted from classifying baseline CES-D ≥ 16 among HIV-infected MSM (sensitivity = 75.0%, 95% CI:67.3%-81.7%) and four consecutive CES-Ds ≥ 16 among HIV-uninfected MSM (sensitivity = 81.0%, 95% CI:73.7%-87.0%). CONCLUSION: Choice of method should vary, depending on importance of false positive or negative rate for long-term depression in HIV-infected and HIV-uninfected MSM.

RESUMEN

HIV testing remains a critical point of entry to HIV treatment services and now biomedical prevention as well. Yet despite the high HIV prevalence among Black men who have sex with men (MSM), insufficient attention has been given to factors associated with those Black MSM in the United States who have never received an HIV test in their lifetime. Promoting Our Worth, Equality, & Resilience (POWER) is a cross-sectional observational study that recruited Black MSM at Black Pride events across six cities in the United States from 2014 to 2017. Participants completed an anonymous questionnaire and were offered free, confidential HIV testing. Of the 4174 Black MSM without a prior HIV diagnosis, 404 (9.68%) had never tested for HIV (mean age = 31.03 years). Lower education and greater internalized homophobia were associated with never having tested for HIV. Higher age (AOR = 1.05, 95%, 1.02-1.07) and assumption of HIV-positivity (AOR = 3.24, 95% CI 1.53-6.84) were both associated with increased odds of an HIV-positive test result (n = 119; 36%). To compare, HIV prevalence among Black MSM who had received at least one HIV test before study participation was 23%. While a minority of Black MSM had never received an HIV test, this group had a significantly higher likelihood of HIV infection. Alternative HIV testing strategies are needed to facilitate HIV testing initiation among Black MSM for whom conventional HIV testing modalities are insufficient.

RESUMEN

OBJECTIVES: We sought to calculate HIV incidence in a retrospective cohort of young (13-29 years old) black men who have sex with men (YBMSM) accessing repeated HIV-antibody testing in a mid-size city in the USA. METHODS: We aggregated site-specific HIV-antibody testing results from the project's inception among YBMSM who received an initial negative result and accessed at least one additional HIV-antibody test. From these data, we assessed number of seroconversions and person-years and calculated HIV incidence using a mid-P exact test to estimate 95% CIs. RESULTS: Five seroconversions were documented over 42.3 person-years (the mean age at first onsite test: 19.7 years), resulting in an HIV incidence rate of 11.8% (95% CI 4.3% to 26.2%). The mean age at seroconversion was 20.4 (±3.0) years. CONCLUSIONS: Even in mid-size cities with low HIV prevalence rates in the general population, HIV incidence among YBMSM may be high. Community-based HIV-antibody testing organisations serving YBMSM should be encouraged and trained to track repeated HIV testing and calculate HIV incidence rates. Increased resources should be deployed to develop and encourage regular HIV testing in community health sites serving YBMSM.

RESUMEN

The deleterious effects of HIV stigma on HIV+ Black MSM care continuum outcomes have been well-documented. How HIV stigma shapes HIV prevention for HIV- persons in this community is poorly understood. We sought to test the relationship of HIV stigma with HIV- Black MSM on HIV testing, pre-exposure prophylaxis (PrEP) awareness, and PrEP use. We recruited 772 participants at Black Pride events across five US cities in 2016. Multivariable logistic regression models assessed the association of external HIV stigma on prevention outcomes adjusting for sociodemographic variables. Stigma was positively associated with PrEP awareness (AOR = 1.34; 95% CI = 1.09, 1.66; p value = 0.005), and not associated with PrEP use or HIV testing in our sample. These findings highlight the complex nature of HIV stigma among BMSM and include results for PrEP, which can affect uptake other prevention methods. We support anti-HIV stigma efforts and advise further exploration on HIV stigma among BMSM and prevention outcomes.

RESUMEN

Older HIV-infected men are at higher risk for both depression and cognitive impairments, compared to HIV-uninfected men. We evaluated the association between longitudinal patterns of depressive symptoms and attention/executive function in HIV-infected and HIV-uninfected men aged 50+ years to understand whether HIV infection influenced the long-term effect of depression on attention/executive function. Responses to the Center for Epidemiologic Studies-Depression scale and attention/executive function tests (Trail Making Test Part B and Symbol Digit Modalities Test) were collected semiannually from May 1986 to April 2015 in 1611 men. Group-based trajectory models, stratified by HIV status, were used to identify latent patterns of depressive symptoms and attention/executive function across 12 years of follow-up. We identified three depression patterns for HIV-infected and HIV-uninfected men (rare/never 50.0 vs. 60.6%, periodically depressed 29.6 vs. 24.5%, chronic high 20.5 vs.15.0%, respectively) and three patterns of attention/executive function for HIV-infected and HIV-uninfected men (worst-performing 47.4 vs. 45.1%; average 41.9 vs. 47.0%; best-performing 10.7 vs. 8.0%, respectively). Multivariable logistic regression models were used to assess associations between depression patterns and worst-performing attention/executive function. Among HIV-uninfected men, those in the periodically depressed and chronic high depressed groups had higher odds of membership in the worst-performing attention/executive function group (adjusted odds ratio [AOR] = 1.45, 95% CI 1.04, 2.03; AOR = 2.25, 95% CI 1.49, 3.39, respectively). Among HIV-infected men, patterns of depression symptoms were not associated with patterns of attention/executive function. Results suggest that HIV-uninfected, but not HIV-infected, men with chronic high depression are more likely to experience a long-term pattern of attention/executive dysfunction.

RESUMEN

Attacks on peoples' dignity help to produce and maintain stigmatization and interpersonal hostility. As part of an effort to develop innovative measures of possible pathways between structural interventions or socially-disruptive Big Events and HIV outbreaks, we developed items to measure dignity denial. These measures were administered to 300 people who inject drugs (PWID), 260 high-risk heterosexuals who do not inject drugs, and 191 men who have sex with men who do not inject drugs (MSM). All of the PWID and many of the high risk heterosexuals and MSM were referred to our study in 2012-2015 by a large New York city study that used respondent-driven sampling; the others were recruited by chain-referral. Members of all three key populations experienced attacks on their dignity fairly often and also reported frequently seeing others' dignity being attacked. Relatives are major sources of dignity attacks. MSM were significantly more likely to report having their dignity attacked by police officers than were the other groups. 40 % or more of each key population reported that dignity attacks are followed "sometimes" or more often both by using more drugs and also by using more alcohol. Dignity attacks and their health effects require more research and creative interventions, some of which might take untraditional forms like social movements.

RESUMEN

Though functional social support has been shown to serve as a protective factor for HIV viral load suppression in other populations, scant research has examined this relationship among men who have sex with men (MSM) in the United States. We assessed characteristics of social support, effects of social support on HIV viral load, and moderation by social support of the relationship between psychosocial indicators of a synergistic epidemic (syndemic) and HIV viral load. We analyzed longitudinal data from HIV-positive MSM using antiretroviral therapy who were enrolled in the Multicenter AIDS Cohort Study between 2002 and 2009 (n = 712). First, we conducted reliability assessments of a one-item social support measure. Then, we conducted a series of generalized longitudinal mixed models to assess our research questions. Moderation was assessed using an interaction term. A three-level (low/medium/high) social support variable demonstrated high reliability (intraclass correlation coefficients = 0.72; 95% CI: 0.70, 0.75). Black and Hispanic MSM reported lower social support than their White counterparts (p < .0001). Recent sero-conversion was associated with higher social support (p < .05). Higher numbers of concomitant syndemic indicators (depression, polysubstance use, and condomless anal sex) were associated with lower social support (p < .0001). Medium and high social support levels were associated with greater viral load suppression and lower viral load means (p < .0001). Social support moderated the relationships between syndemic and HIV viral load (p < .05). HIV-positive MSM, particularly those of color, may benefit greatly from interventions that can successfully boost functional social support. Creating strengths-based interventions may also have particularly high impact among HIV-positive MSM with the highest psychosocial burdens.

RESUMEN

Bisexual men experience significant health disparities likely related to biphobia. Biphobia presents via several preconceptions, including that bisexuality is transitory, and that bisexual men act as viral bridges between men who have sex with men and heterosexual populations. We analyzed data from a prospective cohort of gay and bisexual men, the Multicenter AIDS Cohort Study, to test these preconceptions. Men reporting both male and female sexual partners (MSMW) between 2002 and 2009 (n = 111) were classified as behaviorally bisexual. We assessed five hypotheses over two domains (transience of bisexual behavior and viral bridging). No evidence was found supporting the transitory nature of bisexuality. Trajectories of bisexual behavior were not transient over time. We found little evidence to support substantial viral bridging behavior. Notably, HIV-positive MSMW reported lower proportions of female partners than HIV-negative MSMW. Our results provide no empirical support for bisexual transience and scant support for viral bridging hypotheses. Our results provide key data showing that male bisexual behavior may be stable over long time periods and that behaviorally bisexual men's risk to female sexual partners may be lower than expected.

RESUMEN

The HIV epidemic among Black men and transgender women who have sex with men (BMTW) demands an urgent public health response. HIV point prevalence among this population ranges from 25 to 43%-a rate far exceeding any other group. Pre-exposure prophylaxis (PrEP) for HIV prevention is a very promising prevention tool; however, its full potential to slow the epidemic has yet to be realized. For the current study, random time-location sampling at Black Gay Pride Events was used to collect data from N = 1274 BMTW, from five US cities, reporting HIV-negative/unknown status. In-field HIV testing was also provided to participants. Participants were assessed on awareness and use of PrEP, health care factors, HIV testing history, psychosocial variables, and sex behaviors. About one third of participants were aware of PrEP (39%), and a small percentage of participants were users of PrEP (4.6%). In multivariable analyses, being in a relationship, testing for HIV in the past 6 months, and others being aware of one's sexuality were positively associated with PrEP awareness. Higher levels of internalized homophobia and greater numbers of female sex partners were positively associated with PrEP use, while education and condom use were negatively associated. Based on study findings, messaging and uptake of PrEP needs greater expansion and requires novel approaches for scale-up. Improving linkage to HIV testing services is likely critical for engaging BMTW with PrEP. The potential for PrEP to slow the HIV epidemic is high; however, we must strengthen efforts to ensure universal availability and uptake.

RESUMEN

OBJECTIVES: To examine sexual-orientation differences in positive youth development, and how bullying victimization mediated these differences in a sample of adolescents. METHODS: In 2007 to 2008, positive youth development was measured in 1870 adolescents from US schools and after-school programs in 45 states by using the validated Five Cs model of competence, confidence, connection, character, and caring/compassion. Sexual-minority youths (6.8%) reported having same- or both-gender sexual attractions. Nonattracted youths (4.2%) reported having no sexual attractions. RESULTS: Compared with sexual-minority youths, heterosexual and nonattracted youths had lower odds of being a victim of bullying. Heterosexual and nonattracted youths also had higher average scores in competence, confidence, and connection, but these associations between sexual orientation and positive youth development scores were partly attributable to lack of bullying victimization. CONCLUSIONS: Designing, implementing, and evaluating interventions that reduce bullying can give sexual-minority youths access to several building blocks of health and well-being.

RESUMEN

OBJECTIVES: We sought to determine whether contextual factors shape injection drug use among Black adolescents and adults. METHODS: For this longitudinal study of 95 US metropolitan statistical areas (MSAs), we drew annual MSA-specific estimates of the prevalence of injection drug use (IDU) among Black adolescents and adults in 1993 through 2007 from 3 surveillance databases. We used existing administrative data to measure MSA-level socioeconomic status; criminal justice activities; expenditures on social welfare, health, and policing; and histories of Black uprisings (1960-1969) and urban renewal funding (1949-1974). We regressed Black IDU prevalence on these predictors by using hierarchical linear models. RESULTS: Black IDU prevalence was lower in MSAs with declining Black high-school dropout rates, a history of Black uprisings, higher percentages of Black residents, and, in MSAs where 1992 White income was high, higher 1992 Black income. Incarceration rates were unrelated. CONCLUSIONS: Contextual factors shape patterns of drug use among Black individuals. Structural interventions, especially those that improve Black socioeconomic security and political strength, may help reduce IDU among Black adolescents and adults.

RESUMEN

MSM refugees have to deal with personal challenges and social/structural adversaries based on their refugee status on top of their sexual identity. To better customize interventions beside this population, we explored psycho-social and structural correlates of condom use and HIV testing in Lebanon by surveying and testing 150 participants. 67 % self-identified as gay. 84.6 % reported any unprotected anal intercourse (UAI) with men in the prior 3 months. Those who engaged in UAI, were lest comfortable with a doctor, didn't know where to get free HIV testing, experienced discrimination based on their refugee status and spent more time with their refugee peers, were less inclined to have seen a doctor in the past 12 month or knew where to get free HIV testing. Ever having been HIV tested was associated with being comfortable with medical doctors, knowing where to get HIV testing and spending time with other peer refugees. HIV prevention and testing promotion efforts targeting MSM refugees need to account for structural barriers, while fighting discrimination is crucial for a healthy sexual identity development.
