Use of antiretroviral therapies among HIV-infected men who have sex with men: a household-based sample of 4 major American cities

A new approach to measuring the synergy in a syndemic: Revisiting the SAVA syndemic among urban MSM in the United States

ABSTRACTSyndemic theory hypothesises that observed clusters of diseases are the result of harmful social conditions. Critiques of syndemics present the theory as ambiguous and lacking empirical evidence. Syndemics are evidenced through qualitative assessments drawing on observations, epidemiology, and biomedical evidence to explain bio-bio and bio-social interactions. Quantitative syndemic studies commonly apply a summative approach, whereby the outcome is a result of the cumulative effect of the individual elements. More recently, quantitative studies apply analyses to assess mechanical interactions among conditions. This paper applies a synergy factor analysis to measure synergy - the enhancement of the effect of one element on the effect of the others. Data from the canonical quantitative syndemic analysis study was reanalysed to assess synergy among the elements of the SAVA syndemic (substance ab/use, violence, HIV/AIDS). Contrary to original study findings, which applied a summative approach, no synergy was measured. Synergistic interactions were confirmed among a subset of the study population; the effects of substance ab/use and violence on HIV were more than two times greater in White MSM than the predicted joint effect (SF = 2·32, 95%CI 1·02-5·11, p = 0·044), indicating synergy. Synergy factor analysis presents an accessible tool to measure syndemic interactions and facilitate timely global health responses.

HIV Stigma, Homophobia, Sexual and Gender Minority Community Connectedness and HIV Testing Among Gay, Bisexual, and Other Men and Transgender People Who Have Sex with Men in Kazakhstan

Although HIV incidence is rising among gay, bisexual, and other men (MSM) and transgender people who have sex with men (TSM) in Kazakhstan, whether stigmatizing attitudes and connectedness are associated with HIV testing in this region is not known. We analyzed data from one-time interviews with 304 adult MSM and TSM conducted 2018-2019 in three cities in Kazakhstan. Logistic regression determined whether HIV stigma, internalized homophobia, sexual and gender minority (SGM) connectedness predicted HIV testing (within the lifetime, past year, and past 6 months) before and after adjustment for sociodemographic characteristics. 80% of participants reported ever receiving an HIV test. Gay-identified participants reported less HIV stigma and internalized homophobia as well as greater connectedness relative to those with bisexual or other identities. In adjusted models, those who had ever tested reported lower HIV stigma (aOR 0.83, 95% CI 0.76-0.91, P < .001) and higher connectedness (aOR 1.17, 95% CI 1.06-1.29, P = .003) than those who had not; those who had ever tested reported lower internalized homophobia in the unadjusted model only (OR 0.95, 95% CI 0.91-0.99, P = .01). Similar differences and trends were found in models examining testing in the past year and past 6 months. Addressing stigmatizing attitudes and connectedness may improve uptake of HIV testing among MSM and TSM in Kazakhstan.

Prospective Effects of a Syndemic on HIV and STI Incidence and Risk Behaviors in a Cohort of Young Men Who Have Sex with Men

Young men who have sex with men continue to be highly affected by HIV. To improve understanding of the role that multiple co-occurring health issues (i.e., syndemics) play in HIV acquisition, sophisticated modeling methods are needed. The purpose of this study was to use structural equation modeling to understand the structure of the syndemic and to test its longitudinal association with condomless anal sex. Data are from a longitudinal study of 450 YMSM. A primary syndemic component comprised of substance use, violence, and internalizing mental health factors significantly predicted the number of condomless anal sex partners in the full sample. Analyses exploring associations by race/ethnicity found a significant association among White YMSM, but not among Black or Latino YMSM. Higher-order factor modeling suggests these psychosocial factors form a syndemic in all racial/ethnic groups, but the syndemic, as conceptualized here, may be less relevant to racial/ethnic minority YMSM.

HIV among Black men who have sex with men (MSM) in the United States: a review of the literature

In 2006, Millett published a seminal literature review that examined 12 hypotheses to explain the high rates of HIV among black MSM. This paper augments Millett's article by reviewing the recent literature on behavioral, biomedical, structural, social contextual, psychosocial, and social network factors that affect HIV rates among black MSM. We searched three databases: PubMed, Scopus, and Google Scholar. First we searched all articles that included black or African American and MSM and HIV. We then searched the following terms for each area: behavioral (drug use during sex, crack cocaine use, and serosorting); biomedical (circumcision, STDs, and STIs); structural (access to care, HIV care, ART, HAART, patient-provider communication, HIV quality of care); social contextual (stigma, discrimination, internalized homophobia, internalized heterosexism, medical mistrust, social isolation, and incarceration); psychosocial (peer support and mental health); and social network (sexual mixing, partner characteristics, and social networks) factors. We identified 39 articles to include in this review. We found inconclusive evidence that incarceration, stigma, discrimination, social isolation, mental health disparities, or social networks explain the elevated rates of HIV among black MSM. We found evidence that the differences in rates of HIV between black and white MSM may be explained by differences in STIs, undiagnosed seropositivity, access to care and treatment services, and use of HAART. There is an overwhelming need for HIV testing, linkage to care, retention in care, and adherence programs for black MSM.

Levels and predictors of HIV risk behavior among Black men who have sex with men

Black men who have sex with men (MSM) contract HIV at disproportionately high rates, and National HIV/AIDS Strategy goals to reduce HIV incidence cannot be successful without improved HIV prevention among racial minority MSM. A total of 210 Black MSM from three cities (Cleveland, Miami, and Milwaukee) completed measures assessing their sexual behavior and demographic characteristics, as well as AIDS-specific psychosocial scales, broader contextual domains, and substance use. Nearly 50% of men reported recent unprotected anal intercourse (UAI), often with non-main partners, with partners not known to be HIV seroconcordant, or with multiple partners. Thirty-seven percent of men reported being HIV positive. In multiple regression analyses, higher levels of unprotected behavior were predicted by weaker perceived peer norms for condom use, weaker risk reduction behavioral intentions, being HIV negative, and recent use of marijuana, cocaine/crack, and poppers. Greater number of UAI partners was associated with weaker perceived peer condom use norms, lower risk reduction intentions, illicit use of prescribed opiates, and fewer AIDS conspiracy beliefs. These findings suggest important factors that should be targeted in HIV prevention programs for Black MSM.

Measuring community connectedness among diverse sexual minority populations

Theory and research agree that connectedness to the lesbian, gay, bisexual, and transgender (LGBT) community is an important construct to account for in understanding issues related to health and well-being among gay and bisexual men. However, the measurement of this construct among lesbian and bisexual women or racial and ethnic minority individuals has not yet been adequately investigated. This study examined the reliability and validity of an existing measure of connectedness to the LGBT Community among a diverse group of sexual minority individuals in New York City, and whether differences in connectedness existed across gender and race or ethnicity. Scores on the measure demonstrated both internal consistency and construct stability across subgroups defined by gender and race or ethnicity. The subgroups did not differ in their mean levels of connectedness, and scores on the measure demonstrated factorial, convergent, and discriminant validity, both generally and within each of the subgroups. Inconsistencies were observed with regard to which scores on the measure demonstrated predictive validity in their associations with indicators of mental health and well-being. The scale is a useful tool for researchers and practitioners interested in understanding the role of community connectedness in the lives of diverse populations of sexual minority individuals.

Conspiracy beliefs about HIV are related to antiretroviral treatment nonadherence among african american men with HIV

BACKGROUND

Medical mistrust is prevalent among African Americans and may influence health care behaviors such as treatment adherence. We examined whether a specific form of medical mistrust-HIV conspiracy beliefs (eg, HIV is genocide against African Americans)-was associated with antiretroviral treatment nonadherence among African American men with HIV.

METHODS

On baseline surveys, 214 African American men with HIV reported their agreement with 9 conspiracy beliefs, sociodemographic characteristics, depression symptoms, substance use, disease characteristics, medical mistrust, and health care barriers. Antiretroviral medication adherence was monitored electronically for one month postbaseline among 177 men in the baseline sample.

RESULTS

Confirmatory factor analysis revealed 2 distinct conspiracy belief subscales: genocidal beliefs (eg, HIV is manmade) and treatment-related beliefs (eg, people who take antiretroviral treatments are human guinea pigs for the government). Both subscales were related to nonadherence in bivariate tests. In a multivariate logistic regression, only treatment-related conspiracies were associated with a lower likelihood of optimal adherence at one-month follow-up (odds ratio = 0.60, 95% confidence interval = 0.37 to 0.96, P < 0.05).

CONCLUSIONS

HIV conspiracy beliefs, especially those related to treatment mistrust, can contribute to health disparities by discouraging appropriate treatment behavior. Adherence-promoting interventions targeting African Americans should openly address such beliefs.

Measuring sexual risk for HIV: a Rasch scaling approach

In this study, we developed an HIV transmission risk scale and examined its psychometric properties using data on sexual behavior obtained from a probability sample of adult men who have sex with men living in Chicago. We used Messick's (Am Psychol 50:741-749, 1995) conceptualization of unified validity theory to organize the psychometric properties of data. Evidence related to scale content was investigated via Rasch item fit statistics, point-measure correlations, and expert evaluation. The substantive aspect of validity was addressed by interpreting the meaningfulness of the item difficulty hierarchy (continuum of risky behaviors) and assessment of person fit. The structural aspect of validity was assessed using Rasch item fit statistics, principal component analysis of standardized residuals, and other residual analyses. The generalizability aspect of validity was investigated via internal consistency reliability estimates for both items and persons, and aspects of external validity were addressed by examining between-group differences with respect to levels of risky behavior. Applications and suggested future studies are discussed.

The effect of intrinsic stochasticity on transmitted HIV drug resistance patterns

Estimates of transmitted HIV drug-resistance prevalence vary widely among and within epidemiological surveys. Interpretation of trends from available survey data is therefore difficult. Because the emergence of drug-resistance involves small populations of infected drug-resistant individuals, the role of stochasticity (chance events) is likely to be important. The question addressed here is: how much variability in transmitted HIV drug-resistance prevalence patterns arises due to intrinsic stochasticity alone, i.e., if all starting conditions in the different epidemics surveyed were identical? This 'thought experiment' gives insight into the minimum expected variabilities within and among epidemics. A simple stochastic mathematical model was implemented. Our results show that stochasticity alone can generate a significant degree of variability and that this depends on the size and variation of the pool of new infections when drug treatment is first introduced. The variability in transmitted drug-resistance prevalence within an epidemic (i.e., the temporal variability) is large when the annual pool of all new infections is small (fewer than 200, typical of the HIV epidemics in Central European and Scandinavian countries) but diminishes rapidly as that pool grows. Epidemiological surveys involving hundreds of new infections annually are therefore needed to allow meaningful interpretation of temporal trends in transmitted drug-resistance prevalence within individual epidemics. The stochastic variability among epidemics shows a similar dependence on the pool of new infections if treatment is introduced after endemic equilibrium is established, but can persist even when there are more than 10,000 new infections annually if drug therapy is introduced earlier. Stochastic models may therefore have an important role to play in interpreting differences in transmitted drug-resistance prevalence trends among epidemiological surveys.

HIV prevention for black men who have sex with men in the United States

The HIV/AIDS epidemic has exacted a devastating toll upon Black men who have sex with men (MSM) in the United States, and there is a tremendous need to escalate HIV-prevention efforts for this population. The social context in which Black MSM experience the impact of racism and heterosexism strongly affects their risk for HIV infection; thus, HIV-prevention research focused on Black MSM should focus on contextual and structural factors. There is a pronounced lack of community-level HIV-intervention research for Black MSM, but effective preliminary strategies involve adapting existing effective models and tailoring them to the needs of Black MSM. Future research should develop new, innovative approaches, especially structural interventions, that are specifically targeted toward HIV prevention among Black MSM.

Greater risk for HIV infection of black men who have sex with men: a critical literature review

HIV rates are disproportionately higher for Black men who have sex with men (MSM) than for other MSM. We reviewed the literature to examine 12 hypotheses that might explain this disparity. We found that high rates of HIV infection for Black MSM were partly attributable to a high prevalence of sexually transmitted diseases that facilitate HIV transmission and to undetected or late diagnosis of HIV infection; they were not attributable to a higher frequency of risky sexual behavior, nongay identity, or sexual nondisclosure, or to reported use of alcohol or illicit substances. Evidence was insufficient to evaluate the remaining hypotheses.Future studies must address these hypotheses to provide additional explanations for the greater prevalence of HIV infection among Black MSM.

The epidemiological impact of antiretroviral use predicted by mathematical models: a review

This review summarises theoretical studies attempting to assess the population impact of antiretroviral therapy (ART) use on mortality and HIV incidence. We describe the key parameters that determine the impact of therapy, and argue that mathematical models of disease transmission are the natural framework within which to explore the interaction between antiviral use and the dynamics of an HIV epidemic. Our review focuses on the potential effects of ART in resource-poor settings. We discuss choice of model type and structure, the potential for risk behaviour change following widespread introduction of ART, the importance of the stage of HIV infection at which treatment is initiated, and the potential for spread of drug resistance. These issues are illustrated with results from models of HIV transmission. We demonstrate that HIV transmission models predicting the impact of ART use should incorporate a realistic progression through stages of HIV infection in order to capture the effect of the timing of treatment initiation on disease spread. The realism of existing models falls short of properly reproducing patterns of diagnosis timing, incorporating heterogeneity in sexual behaviour, and describing the evolution and transmission of drug resistance. The uncertainty surrounding certain effects of ART, such as changes in sexual behaviour and transmission of ART-resistant HIV strains, demands exploration of best and worst case scenarios in modelling, but this must be complemented by surveillance and behavioural surveys to quantify such effects in settings where ART is implemented.

Risk factors for early syphilis among gay and bisexual men seen in an STD clinic: San Francisco, 2002-2003

BACKGROUND

Substantial increases in syphilis among gay and bisexual men have been reported in San Francisco.

GOAL

To identify risk factors for early syphilis infection among gay and bisexual men attending the San Francisco municipal STD clinic (City Clinic).

STUDY

Cross-sectional, self-administered, behavioral survey of gay and bisexual men attending City Clinic between November 2002 and March 2003 linked with electronic medical record data.

RESULTS

Among 1318 gay and bisexual men surveyed, 53 (4.0%) were diagnosed with early syphilis. The final multivariate model included nonwhite race (OR = 2.1 [1.1-4.4]), HIV-infection (OR = 3.9 [2.0-7.7]), using both methamphetamine and sildenafil (Viagra(R)) (OR = 6.2 [2.6-14.9]), using methamphetamine without sildenafil (OR = 3.2 [1.3-7.6]), using sildenafil without methamphetamines (OR = 0.9 [0.3-2.9]), stronger gay community affiliation (OR = 2.3 [1.2-4.6]), and having recent Internet partners (OR = 2.1 [1.0-4.3]).

CONCLUSIONS

Syphilis prevention efforts should address methamphetamine and sildenafil use among gay and bisexual men and require strong and substantive involvement with the gay community to address syphilis in San Francisco.

Insurance coverage, usual source of care, and receipt of clinically indicated care for comorbid conditions among adults living with human immunodeficiency virus

BACKGROUND AND OBJECTIVES

Associations of insurance coverage and source of care with use of human immunodeficiency virus (HIV)-related health, mental health, and substance abuse services are examined in a large, diverse, highly active antiretroviral therapy-era cohort.

METHODS

Adults who were infected with HIV (n = 3818) were interviewed in clinics and community agencies in Los Angeles, Milwaukee, New York, and San Francisco regarding drug use behaviors, health status, and health care utilization.

RESULTS

Most participants were insured by Medicaid. During the previous 3 months, 90% of privately insured, 87% of publicly insured, and 78% of uninsured participants had visited any provider. Publicly and privately insured participants were similar in receipt of antiretrovirals, prophylaxis against Pneumocystis carinii pneumonia, substance abuse services, and antidepressants. Uninsured participants were less likely to receive antiretrovirals but were more likely to use substance abuse services. Participants with no usual source of care were less likely to receive PCP prophylaxis.

CONCLUSIONS

A lack of insurance is associated with barriers to care, but the advantage of private over public coverage appears smaller than in previous studies. PCP prophylaxis, substance abuse treatment, and antidepressants remain markedly underutilized. Educational initiatives about these treatments targeting providers and patients are indicated.

Decline in HIV infectivity following the introduction of highly active antiretroviral therapy

OBJECTIVE

Little is known about the degree to which widespread use of antiretroviral therapy in a community reduces uninfected individuals' risk of acquiring HIV. We estimated the degree to which the probability of HIV infection from an infected partner (the infectivity) declined following the introduction of highly active antiretroviral therapy (HAART) in San Francisco.

DESIGN

Homosexual men from the San Francisco Young Men's Health Study, who were initially uninfected with HIV, were asked about sexual practices, and tested for HIV antibodies at each of four follow-up visits during a 6-year period spanning the advent of widespread use of HAART (1994-1999).

METHODS

We estimated the infectivity of HIV (per-partnership probability of transmission from an infected partner) using a probabilistic risk model based on observed incident infections and self-reported sexual risk behavior, and tested the hypothesis that infectivity was the same before and after HAART was introduced.

RESULTS

A total of 534 homosexual men were evaluated. Decreasing trends in HIV seroincidence were observed despite increases in reported number of unprotected receptive anal intercourse partners. Conservatively assuming a constant prevalence of HIV infection between 1994 and 1999, HIV infectivity decreased from 0.120 prior to widespread use of HAART, to 0.048 after the widespread use of HAART- a decline of 60% (P=0.028).

CONCLUSIONS

Use of HAART by infected persons in a community appears to reduce their infectiousness and therefore may provide an important HIV prevention tool.

"Informed altruism" and "partner restriction" in the reduction of HIV infection in injecting drug users entering detoxification treatment in New York City, 1990-2001

OBJECTIVE

To assess recent developments in the HIV epidemic in injecting drug users (IDUs) in New York City. With >50,000 cases of AIDS in IDUs, New York has experienced the largest HIV/AIDS epidemic in IDUs of any city in the world.

METHODS

Serial cross-sectional surveys conducted continuously from 1990 to 2001 of IDUs entering the Beth Israel Medical Center (BIMC) drug detoxification program in New York City. HIV serostatus, use of prevention services, and risk behaviors were measured. Individuals were permitted to participate multiple times in the surveys but not more than once in any year.

RESULTS

Two thousand eight hundred eighty-seven individuals contributed 3100 observations from 1990 to 2001. There was a substantial and consistent decline in the prevalence of HIV infection among IDUs entering the BIMC detoxification program, from 54% (165/304) in 1991 to 13% (39/303) in 2001 (P < 0.0001). The decline was highly linear, with r2 = 0.92 and a slope of -3.7% in seroprevalence per year. The decline occurred for both males and females, both short and long-term IDUs, and the three largest racial/ethnic subgroups (all P < 0.001 by Cochran-Armitage testing). Use of HIV prevention services increased substantially, particularly syringe exchange and voluntary HIV counseling and testing. General reductions in injection risk behaviors occurred, but substantial numbers of IDUs continued to engage in both receptive and distributive syringe sharing. Two conditional types of risk reduction not currently recommended by health authorities were reported: "informed altruism," in which persons who knew that they were HIV seropositive reduced transmission behavior, and "partner restriction," in which persons who shared needles and syringes primarily confined this sharing within small social networks.

CONCLUSIONS

HIV infection continues to decline in this population of IDUs in New York City, suggesting the possibility of bringing very high prevalence epidemics under control. Risk elimination may not be required; rather, multiple forms of risk reduction may be effective in reducing HIV transmission within a local population of IDUs.

Changes in the transmission dynamics of the HIV epidemic after the wide-scale use of antiretroviral therapy could explain increases in sexually transmitted infections: results from mathematical models

BACKGROUND

Recent increases in bacterial sexually transmitted infections (STI) and risk behavior have coincided with the introduction of antiretroviral therapy (ART) in homosexual communities of industrialized countries. The reasons for these increases are not fully understood.

GOAL

The goal of this study was to understand the various effects of ART on risk behaviors and STI.

OBJECTIVE

The objective of this study was to assess the independent impact of the change in the transmission dynamics of HIV/AIDS as a result of the wide-scale use of ART on a bacterial STI.

STUDY DESIGN

We developed a mathematical model of bacterial STI and treated/untreated HIV/AIDS infection for an open homosexual population. At the individual level, we assume that susceptible and healthy HIV-positive individuals do not increase their risk behavior as a result of ART over time. However, individuals with AIDS, who are successfully treated with ART, can resume sexual activity. The impact of the wide-scale use of ART on risky behavior, STI, and HIV/AIDS was evaluated over a wide range of assumptions on treatment use, ART efficacy, and population characteristics.

RESULTS

Over 10 years, 0% to 55% new bacterial STI could be attributed to the wide-scale use of ART as a result of more modest increases (0-25%) in risky sex occurring at the population level rather than at the individual level. These increases have a negative impact on HIV if coverage is too low. Increasing treatment coverage helps to prevent more HIV infections despite larger increases in risky sex and STI that is predicted to ensue.

CONCLUSION

Taking the differential impact of wide-scale use of ART into account helps to interpret recent behavioral and STI trends. Our results have implications for prevention strategies and for the formulation of public health policies. A better understanding of the differential impact of ART on sexual network over time is required.

CONCLUSIONS

Use of HAART by infected persons in a community appears to reduce their infectiousness and therefore may provide an important HIV prevention tool.

Association of co-occurring psychosocial health problems and increased vulnerability to HIV/AIDS among urban men who have sex with men

OBJECTIVES

We measured the extent to which a set of psychosocial health problems have an additive effect on increasing HIV risk among men who have sex with men (MSM).

METHODS

We conducted a cross-sectional household probability telephone sample of MSM in Chicago, Los Angeles, New York, and San Francisco.

RESULTS

Psychosocial health problems are highly intercorrelated among urban MSM. Greater numbers of health problems are significantly and positively associated with high-risk sexual behavior and HIV infection.

CONCLUSIONS

AIDS prevention among MSM has overwhelmingly focused on sexual risk alone. Other health problems among MSM not only are important in their own right, but also may interact to increase HIV risk. HIV prevention might become more effective by addressing the broader health concerns of MSM while also focusing on sexual risks.

Public policy regulating private and public space in gay bathhouses

Public policies prohibiting either public or private space in gay bathhouses vary across cities. New York, San Francisco, Los Angeles, and Chicago all have different policies. The objective of this study was to assess reported risk behavior as an indicator of success of one policy over another. Data are from a telephone survey of a probability sample of men living in the four cities who reported having sex with men. Analyses focused on city differences in behavior of adult men who, in the past year, were sexually active with a male and visited a bathhouse ( n= 827). Respondents reported numbers of sex partners, one-night stands, visits to bathhouses in the past year, and casual sex partners with whom they had engaged in unprotected anal intercourse (UAI) as well as whether they had UAI in a public setting. Among men who visit bathhouses, no significant city differences were observed except that there were city differences in where UAI occurred-i.e., San Francisco men were significantly less likely to report UAI in a public place than were men in other cities. The data suggest that different city policies may affect where, but not whether, UAI occurs.

Sexually transmitted diseases surveillance among incarcerated men who have sex with men--an opportunity for HIV prevention

There is an urgent need for behavioral surveillance and prevention strategies specifically designed for men who have sex with men (MSM) who exhibit high-risk behavior. This report describes a sentinel screening program designed to identify sexually transmitted infections among incarcerated MSM. Approximately 2,200 inmates were screened for HIV, syphilis, gonorrhea, and chlamydia from a segregated unit of men who have sex with men in Los Angeles County Men's Central Jail. A convenience sample of 217 participants was offered a survey to assess risk behaviors. Screening activities yielded a 12.4% HIV, 3.1% chlamydia, 1.5% gonorrhea, and 0.3% early syphilis prevalence. The high HIV prevalence found in this population indicates the opportunity for HIV prevention within sexually transmitted disease (STD) screening of incarcerated MSM. Bridging HIV prevention into STD screening will require the integration of primary and secondary prevention services within the jail including case management, early treatment, and referral services.

Differential HIV risk in bathhouses and public cruising areas

OBJECTIVES

This report investigates differences in risk behaviors among men who have sex with men (MSM) who went to gay bathhouses, public cruising areas, or both.

METHODS

We used a probability sample of MSM residing in 4 US cities (n = 2,881).

RESULTS

Men who used party drugs and had unprotected anal intercourse with nonprimary partners were more likely to go to sex venues than men who did not. Among attendees, MSM who went to public cruising areas only were least likely, and those who went to both public cruising areas and bathhouses were most likely to report risky sex in public settings.

CONCLUSIONS

Distinguishing between sex venues previously treated as a single construct revealed a significant association between pattern of venue use and sexual risk. Targeting HIV prevention in the bathhouses would reach the segment of men at greatest risk for HIV transmission.
