Trends in HIV prevalence and risk behavior among men who have sex with men in New York City, 2004-2011

Motivations and Barriers to Routine HIV Testing Among Men Who Have Sex with Men in New York City

In-depth qualitative interviews explored the experiences and understandings of men 18-39 years old who have sex with men that could facilitate or prevent HIV testing and routine HIV testing. For many men who tested frequently, testing and routine testing were motivated by awareness of the benefit of prompt treatment; public health and provider encouragement to test periodically; responsibility towards sexual partners; and wanting to share a recent HIV-negative test result when seeking sex online. For some men, any testing was impeded by anxiety around possible HIV diagnosis that made testing a stressful occasion that required time and energy to prepare for. This anxiety was often compounded by stigma related to sex between men, having condomless sex, or having HIV. Routine testing could be further stigmatized as some men felt judged by testing providers or partners if they asked for a test or said they tested frequently. We describe efforts to promote testing and routine testing by countering fear and stigma associated with HIV and testing.

Combination HIV Prevention Strategies Among Montreal Gay, Bisexual, and Other Men Who Have Sex with Men in the PrEP Era: A Latent Class Analysis

Pre-exposure prophylaxis (PrEP) became publicly available in Quebec for gay, bisexual and other men who have sex with men (GBM) in 2013. We used baseline data from Engage, a cohort of GBM recruited by respondent-driven sampling, to examine patterns of combination HIV prevention use among Montreal GBM since PrEP became available. Latent class analysis, stratified by HIV status, was used to categorize GBM by self-reported use of biomedical and behavioural prevention strategies. Correlates of resulting classes were identified using multinomial logistic regression. Among HIV-negative/unknown GBM (n = 968), we identified four classes: low use of prevention (32%), condoms (40%), seroadaptive behaviour (21%), and biomedical (including PrEP; 7%). Those using prevention (condoms, seroadaptive behaviour, and biomedical) had a higher number of anal sex partners and were more likely to report a recent sexually transmitted infection diagnosis. GBM using biomedical prevention also had a higher level of formal education. Among GBM living with HIV (n = 200), we identified three classes: mainly antiretroviral treatment (ART) with viral suppression (53%), ART with viral suppression and condoms (19%), and ART with viral suppression and seroadaptive behaviour (18%). Again, the number of anal sex partners was higher among those using condoms and seroadaptive behaviours. Our findings show antiretroviral-based prevention, either alone or in combination with other strategies, is clearly a component of the HIV prevention landscape for GBM in Montreal. Nevertheless, PrEP uptake remains low, and there is a need to promote its availability more widely.

Reduction in Gaps in High CD4 Count and Viral Suppression Between Transgender and Cisgender Persons Living With HIV in New York City, 2007-2016

Objectives. To compare trends in HIV outcomes for cisgender and transgender persons living with HIV (PLWH) in New York City.Methods. We used HIV surveillance data for the analysis. We based CD4 count on the last measurement in a calendar year and defined viral suppression as the last viral load being less than or equal to 200 copies per milliliter in the calendar year.Results. The estimated number of PLWH increased from 73 415 in 2007 to 83 299 in 2016, including 606 transgender persons (0.8%) in 2007 and 1054 transgender persons (1.3%) in 2016. The proportion with CD4 count of 500 cells per cubic millimeter or more increased from 38% in 2007 to 61% in 2016 among cisgender persons versus 32% to 60% among transgender persons. The proportion with a suppressed viral load increased from 52% in 2007 to 80% in 2016 among cisgender persons versus 42% to 73% among transgender persons.Conclusions. Among PLWH in New York City, CD4 count and viral suppression improved during 2007 to 2016, with larger improvements among transgender persons, leading to narrower gaps. However, continuing efforts to improve HIV outcomes among transgender PLWH are needed to further eliminate disparities, particularly in viral suppression.

Mental Health and Substance Use Disorder Comorbidity among Methamphetamine-Using Men Who have Sex with Men

Men who have sex with men (MSM) exhibit elevated rates of mental health and substance use disorder relative to their non-MSM male counterparts. Methamphetamine use in particular has been associated with both neuronal damage and mental health disorders among MSM, and this study reports on the prevalence and comorbidity of DSM-5 mental health and substance use disorders in a sample of methamphetamine-using MSM. From March 2014 through January 2015, 286 methamphetamine-using MSM enrolled in a study to reduce methamphetamine use and sexual risk behaviors. At baseline, participants demonstrated high rates of current major depressive episode (35.8%), antisocial personality disorder (23.9%), suicide risk (23.2%), obsessive-compulsive disorder (23.2%), and social phobia (20.4%), as well as methamphetamine use disorder (89.1%), marijuana use disorder (41.0%), alcohol use disorder (39.6%), cocaine use disorder (30.9%), and inhalants use disorder (15.4%). Analyses revealed significant (p < 0.05) associations between methamphetamine use disorder severity and all listed mental health disorders, as well as between alcohol use disorder and all listed mental health disorders. Mental health disorder prevalence and substance use disorder severity were both elevated, and both methamphetamine and alcohol use disorder severity were associated with increased likelihood of comorbid mental health disorder.

Trends in Sexual Behavior Among Men Who have Sex with Men (MSM) in High-Income Countries, 1990-2013: A Systematic Review

HIV diagnoses among men who have sex with men (MSM) have been increasing in several high-income countries. A better understanding of the sexual behavior trends among MSM can be useful for informing HIV prevention. We conducted a systematic review of studies that examined behavioral trends (1990-2013) in any condomless anal sex, condomless anal sex with an HIV-discordant partner, and number of partners. Studies included come from the United States, Europe, and Australia. We found increasing trends in condomless anal sex and condomless anal sex with an HIV-discordant partner, and a decreasing trend in number of partners. The increase in condomless anal sex may help to explain the increase in HIV infections. More explanatory research is needed to provide insight into factors that contribute to these behavior trends. Continuous monitoring of HIV, risk behaviors, and use of prevention and treatment is needed to evaluate prevention efforts and monitor HIV transmission risk.

Brief Report: HIV Prevalence and the Prevalence of Unsuppressed HIV in New York City, 2010-2014

BACKGROUND

The widespread use of antiretroviral treatment made HIV prevalence no longer a good measure of population-level transmission risk. The objective of this analysis was to use the prevalence of unsuppressed HIV to describe population-level HIV transmission risk.

METHODS

Using New York City (NYC) HIV surveillance data, we reported HIV prevalence and the prevalence of unsuppressed HIV, defined as the number of persons living with HIV with an unsuppressed viral load divided by population size.

RESULTS

The estimated number of persons living with HIV in NYC increased from 79,100 [95% confidence interval (CI): 78,200 to 80,000] in 2010 to 81,700 (95% CI: 80,500 to 82,900) in 2014. HIV prevalence (≥18 years old) remained unchanged at 1.22% (95% CI: 1.21% to 1.24%) in 2010 and 1.22% (95% CI: 1.20% to 1.24%) in 2014. The prevalence of unsuppressed HIV (≥18 years old) steadily decreased from 0.49% (95% CI: 0.48% to 0.51%) in 2010 to 0.34% (95% CI: 0.32% to 0.36%) in 2014. Men had both higher HIV prevalence (1.86% vs. 0.65% in 2014) and higher prevalence of unsuppressed HIV (0.51% vs. 0.18% in 2014) than women. In 2014, the black-white ratio of prevalence of unsuppressed HIV was 5.8 among men and 26.3 among women, and the Hispanic-white ratio was 2.7 among men and 10.0 among women.

CONCLUSIONS

The prevalence of unsuppressed HIV has been steadily decreasing in NYC. As antiretroviral treatment continues to expand, programs should consider using the prevalence of unsuppressed HIV to measure population-level transmission risk.

Original title: HIV infection and unawareness among men who have sex with men in Puerto Rico: data from The National HIV behavioral surveillance system 2011-2014

BACKGROUND

Unawareness of HIV infection is a public health challenge that needs to be addressed, particularly in the case of men who have sex with men (MSM), since recent data are reporting increasing rates of HIV in this population in Puerto Rico.

OBJECTIVES

We examined differences in the prevalence of HIV infection and unawareness among MSM in 2011 and 2014 using data from the National HIV Behavioral Surveillance System, 2011 and 2014.

METHODS

Bivariate analyses was used to compare demographical and behavioral characteristics in both cycles (2011 and 2014). Prevalence ratio (PR) was assessed with Poisson regression models to determine changes in HIV prevalence and unawareness across cycles, using the 2011 NHBS-MSM cycle as reference group.

RESULTS

A stable rate in HIV prevalence was observed in 2011 and 2014. There was a higher prevalence in 2014 than in 2011 in multiple behavioral characteristics such as age at sexual initiation, the number of sexual partners in the 12 months prior to being interviewed, HIV testing in the year prior to being interview, and the disclosure of sexual orientation to a healthcare provider. A significant decrease in HIV unawareness was reported (76.67%, 2011; 46.51%, 2014). Age-adjusted regression models showed a marginal reduction of 55% in HIV unawareness for men who disclosed their sexual orientation to their healthcare providers.

CONCLUSION

Behavioral surveillance systems in groups such as MSM in on the island will aid to monitor prospectively the effectiveness of HIV testing outreach and engagement, as well as capacity capacity-building strategies targeted towards health care providers, aimed to increase HIV testing and awareness among this group.

HIV prevalence among men who have sex with men in Istanbul

OBJECTIVES

The re-emergence of the HIV epidemic among men who have sex with men (MSM) represents a serious health issue. This study aimed to assess the HIV prevalence among MSM in a very low prevalence population of a large city.

METHODS

A public campaign to raise awareness of HIV infection and to provide access to anonymous testing was conducted in places frequented by MSM and through a mobile phone application. No identity information was requested from individuals contacting the call centre, and anonymous and free HIV testing was offered proactively. Those who agreed to have a test were provided a code number, which was used in blood sampling procedures.

RESULTS

Of 1200 subjects who contacted the call centre, 197 consented to undergo HIV testing and visited the laboratory to give a blood sample. Twenty-five subjects were found to have a reactive ELISA result on two different occasions plus a positive Western blot test result. Thus, the HIV prevalence in this group of MSM was 12.7%.

CONCLUSIONS

MSM remain a high risk group for HIV infection in a low prevalence setting, and thus represent a key target population for diagnostic and therapeutic interventions.

How Different are Men Who Do Not Know Their HIV Status from Those Who Do? Results from an U.S. Online Study of Gay and Bisexual Men

We compared self-described HIV-positive (31.6 %, n = 445), HIV-negative (56.8 %, n = 801), and HIV-unknown (11.6 %, n = 164) gay and bisexual men on sociodemographic and behavioral characteristics. Participants from across the U.S. were enrolled via a popular sexual networking website to complete an online survey. In total, 44.8 % of HIV-negative and HIV-unknown men said they had not been tested for HIV in the CDC-recommended last 6 months. HIV-unknown men significantly differed from HIV-negative and HIV-positive men in sexual behavior and HIV status disclosure patterns. HIV-unknown men were more willing than HIV-negative men to take PrEP; however, HIV-unknown men were significantly less likely than others to have health insurance or a primary care provider. Given the observed differences, researchers should consider analyzing men who are HIV-unknown distinctly from HIV-negative and HIV-positive men.

Changes in HIV demographic patterns in a low prevalence population: no evidence of a shift towards men who have sex with men

OBJECTIVES

This study aimed to examine the changes in HIV demographics over time in an exceptionally low prevalence population, with particular emphasis on men who have sex with men (MSM).

METHODS

A total of 1292 newly diagnosed HIV-positive patients registered in the ACTHIV-IST Study Group database between 2000 and 2014 were included. The changes occurring over time in the characteristics of patients at the time of initial admission were examined retrospectively.

RESULTS

A gradual increase in the total number of newly diagnosed patients was evident during the study period; however, it was not possible to show an increase in the proportion of MSM within the study population (p=0.63). There was a male predominance throughout the study (85% vs. 15%), with further increases in the proportion of males in recent years. The mean age was lower at the end of the study (p<0.05) and there was an increase in the number of unmarried patients (p<0.05).

CONCLUSIONS

Sexual preference patterns of HIV patients in extremely low prevalence populations may be different, possibly due to an early phase of the epidemic. Nevertheless, MSM still represent a target subgroup for interventions, since they account for a substantial proportion of cases and a resurgent epidemic may be expected among this group in later phases of the epidemic.

Persistent Racial Disparities in HIV Infection in the USA: HIV Prevalence Matters

OBJECTIVES

Despite increased funding and efforts to prevent and control HIV infections in the black and Hispanic communities, racial disparities persist in the USA. We used a mathematical model to explain the phenomena.

METHODS

A mathematical model was constructed to project HIV prevalence ratio (PR), incidence rate ratio (IRR), and HIV-specific mortality rate ratio (MRR) among blacks and Hispanics vs. whites in two scenarios: (1) an annual reduction in HIV incidence rate at the 2007-2010 level and (2) an annual reduction in HIV incidence rate at the 2007-2010 level among whites (4.2 %) and twice that of whites among blacks and Hispanics (8.4 %).

RESULTS

In scenario no. 1, the PR, IRR, and MRR among blacks would decrease from 7.6 to 5.8, 7.9 to 5.9, and 11.3 to 5.3 and among Hispanics from 2.8 to 1.8, 3.1 to 1.9, and 2.3 to 1.0, respectively. In scenario no. 2, the PR, IRR, and MRR among blacks would decrease from 7.6 to 5.1, 7.9 to 2.5, and 11.3 to 4.7 and among Hispanics from 2.8 to 1.6, 3.1 to 0.8, and 2.3 to 0.9, respectively.

CONCLUSIONS

Much of the persistent racial disparities in HIV infection in the USA, as measured by PR, IRR, and MRR, can be explained by higher HIV prevalence among blacks and Hispanics. The public health community should continue its efforts to reduce racial disparities, but also need to set realistic goals and measure progress with sensitive indicators.

Hepatitis B and C Co-Infections in Some HIV-Positive Populations in Cameroon, West Central Africa: Analysis of Samples Collected Over More Than a Decade

As people infected with the human immunodeficiency virus (HIV) in Sub-Saharan Africa live longer due to availability of antiretroviral treatment (ART), so is the rise of associated infections with their burdens on patients. But reliable data on the prevalence of co-infection with hepatitis B (HBV) or C (HCV) still remains sparse and many individuals with HIV do not know their co-infection status. This study attempted to estimate the seroprevalence and identify risk factors associated with hepatitis B and/or C co-infections in HIV-infected individuals from five Regions of Cameroon by screening 531 HIV infected subjects for the presence of HBV surface antigen (HBsAg) and antibodies to HCV (HCV-Ab). A Screening and a confirmatory Enzyme linked immunosorbent assay were used to detect presence of markers of infection. CD4 count levels were also examined. The results indicate that of the 531 participants, 68% were females and 32% males. Mean CD4 count was ~400 cells/μl. Seroprevalence rates for HBsAg and HCV-Ab were 23.7%, and 7.2%, respectively. Associations assessed using logistic regression revealed that HBsAg but not HCV-Ab positivity was linked to age, lower CD4 count and residing in an urban rather than in a rural setting. This high prevalence of co-infection with HBV raises the urgent need to systematically screen all newly diagnosed HIV cases for co-infection in Cameroon and other regions of sub-Saharan Africa where HIV accounts for the majority of the global infection, so as to improve management strategies for HBV infection and ART implementation.

Sexual behaviours of homosexual and bisexual men in France: a generational approach

Objective

In high-income countries, the social and epidemiological contexts surrounding homosexuality and AIDS have changed profoundly in recent decades. This work sought to examine key indicators of the long-term sexual trajectories of successive generations of men who have sex with men (MSM) in France.

Methods

We performed a longitudinal analysis of the French Gay Press surveys, which were self-administered socio-behavioural questionnaires, repeated from 1985 to 2011 in the gay press, and on the internet in 2004 and 2011. An age-cohort analysis using graphical representations and multivariate logistic regressions was conducted among participants aged 18-59 (N=38 821).

Results

First sexual intercourse occurred more often with a male partner in younger generations than in older ones: 76.0% in MSM who turned 18 in 1956-1959, 75.6% in 1980-1983, 83.7% in 2008-2011, p_overall=0.0002). Every generation showed the same pattern of sexual trajectory between 1985 and 2011: globally, the frequency of masturbation increased from the 1985 survey to the early 1990s and then decreased from the late 1990s to the end of the study period. Inversely, the frequency of oral and anal sex decreased in the mid-1980s and increased from 1990 to 2011. The frequency of both oral sex and anal intercourse is currently quite high, regardless of generation (>95% and around 80%, respectively). Compared to their predecessors, recent generations of young MSM reported more frequent oral and anal sex, but fewer male partners in the previous 12 months.

Discussion

While the increased frequency of first intercourse with a man over successive generations since the 1970s may be related to reduced social pressure for heterosexuality, there is evidence that sexual norms among MSM are widespread, with practices spreading across age groups and generations. Although AIDS profoundly affected sexual practices in the 1980s, further AIDS-related events (discovery of HIV antiretroviral drugs and their use in prevention) do not appear to have accentuated ongoing trends in sexual practices.
