Abstract:

The aim of this study was to assess the association between age, depressive symptoms, and substance use among men who have sex with men (MSM) living with HIV. Baseline data were obtained from 337 MSM living with HIV. Linear and logistic regression models were used to determine the association between age and depressive symptoms and substance use. MSM aged 35–49 had higher depressive symptoms than MSM 50 and older (B = 3.53; 95% CI: 0.33, 6.72); MSM aged 25–34 and MSM 35–49 had higher substance use than MSM 50 and older (B = 2.66; 95% CI: 0.77, 4.54; and B = 1.68; 95% CI: 0.22, 3.14, respectively). MSM aged 35–49 were more likely to be at risk for clinical depression than MSM 50 and older (OR = 1.84; 95% CI: 1.06, 3.22); MSM aged 18–24 and MSM 35–49 were less likely and more likely to have substance abuse than MSM 50 and older (OR = 0.29; 95% CI: 0.09, 0.91; and OR = 1.83; 95% CI: 1.02, 3.29, respectively). Interventions addressing depressive symptoms and substance use tailored to individuals in different age groups should account for varying needs at different stages of life.

Abstract:

Sexual risk behaviors account for most HIV infections in men who have sex with men (MSM), and the risk of exposure from each sexual encounter increases with age. The focus of this study was to investigate which behaviors in midlife and older MSM influence their sexual risk/protection. Cross-sectional data were collected from a community-based sample of 802 MSM aged 40 years and older from community venues (e.g., bars) who completed an anonymous questionnaire. Data from a subset of 420 MSM who were HIV-negative (aged 40-81 years) were used to investigate which behaviors were associated with greater risk for unprotected anal sex. Regression analyses indicated that erection difficulties (odds ratio [OR] = 4.7; 95% confidence interval [CI] = 1.8-12.2), practicing safe sex with outside partners but not with one’s primary partner (OR = 0.54; 95% CI = 0.3-0.94), and recreational drug use (OR = 2.6; 95% CI = 1.3-5.1) were associated with higher risk for unprotected receptive anal intercourse. Younger age (OR = 0.96; 95% CI = 0.9- 0.9), not telling partners about HIV status (OR = 3.2; 95% CI = 1.5-6.5), finding partners in backrooms/sex clubs (OR = 2.8; 95% CI = 1.1- 6.8), and erection difficulties (OR = 10.3; 95% CI = 2.8-37.8) were associated with higher risk for unprotected insertive anal intercourse. These data indicate there may be certain factors specific to older MSM that influence their sexual risk taking behaviors. Programs may be more effective if they are tailored for older cohorts of MSM and address interpersonal communication, erection problems, and substance use to reduce health risks and promote healthier lifestyles.

Abstract:

Middle-aged and older men who have sex with men (MSM) are one of the most underestimated populations with regard to HIV/AIDS infection, despite the worldwide trend of increasing prevalence in recent years. This population also has low rates of testing, although rare studies are done exclusively with middle-aged and older MSM assessing the factors associated with this prevalence. Thus, based on data from an exclusive online survey with middle-aged and older MSM who use geolocation-based dating applications, the purpose of the study was to analyze factors associated with not taking the HIV test among middle-aged (50 years old) and older MSM in Brazil. Using a modification of time-location sampling adapted to virtual reality, 412 volunteers were approached in Grindr®, Hornet®, SCRUFF®, and Daddyhunt®. The multivariate logistic regression model was adopted to produce adjusted odds ratios (ORa), considering a significance level at .05. There were factors associated with not taking the test: being in a relationship (ORa: 0.24; 95% CI [0.10, 0.53]); knowing partner through the applications (ORa: 1.84; 95% CI [1.07, 3.15]); not knowing the serological status (ORa: 5.07; 95% CI [1.88, 13.67]); ejacul*ting outside of anal cavity (ORa: 1.79; 95% CI [1.04, 3.05]); practicing sex without penetration (ORa: 2.30; 95% CI [1.17, 4.50]); not taking the test as a form of prevention (ORa: 2.83; 95% CI [1.05, 7.68]); and rarely using Viagra in sexual intercourse (ORa: 1.91; 95% CI [1.20, 3.65]). There is a blind spot in the prevalence of HIV testing in older MSM because this population is not being covered by services, which compromises the overall response to HIV, the goals set for universal health coverage.

Abstract:

Abstract Social support is linked to a myriad of positive health outcomes, yet little is understood about its potential role on frailty development among older men who have sex with men (MSM). We evaluated data from 929 MSM aged 40-81 years enrolled in the MACS Health Aging sub-study. Social support (Social Provisions Scale[SPS-24]; range 24-96) was high, though slightly lower among the HIV-positive versus HIV-negative men (median: 80 vs. 82, p=0.12). Each SD increase in social support associated with a 21% decrease in incident frailty (Fried phenotype), independent of age, race, and education (aIRR=0.79, IQR[0.65, 0.97]), though attenuated after adjustment for depressive symptoms. This protective association was observed to be strongest among HIV-positive MSM. High social support is a strength among older MSM, which associates with positive frailty outcomes. Assessing and strengthening social support systems may have potential as a psychosocial component of frailty interventions.

Abstract:

Abstract Background Relationship status is an important factor associated with condomless anal intercourse (CAI) amongst men who have sex with men (MSM). Methods A multi-centre bio-behavioural survey with MSM was conducted in 13 European cities (n = 4901) exploring factors associated with CAI via bivariate and multivariate multilevel logistic regression analyses. Results Likelihood of CAI with casual partners was associated with being ‘out’ to a majority (AOR = 1.19;95% CI 1,1.42); knowing their HIV status (AOR = 1.86; 95% CI 1.25,2.76); using substances (1–2 AOR = 1.39; 95% CI 1.16,1.63, 2+ AOR = 1.81; 95% CI 1.35,2.42); being older (AOR = 0.98; 95% CI 0.97,0.99); successful sero-communication (AOR = 0.79; 95% CI 0.67,0.94); and, not having a recent HIV test (AOR = 0.78; 95% CI 0.66,0.92). CAI with steady partners was associated with successful sero-communication (AOR = 2.72; 95% CI 2.72,3.66); not having a recent HIV test (AOR = 1.26; 95% CI 1.09,1.46), and; being older (AOR = 0.99; 95% CI 0.98,0.99). Conclusions Understandings of partner type and/or relationship status in relation to CAI amongst MSM can potentially play an important role in the development of culturally appropriate HIV/STI prevention and risk-reduction efforts targeting at-risk MSM. Our results speak to the need to consider segmented and tailored public health and health promotion initiatives for MSM with differing CAI behaviours and relationship profiles.

Abstract:

HIV self-testing has emerged as a safe and effective approach to increase the access to and uptake of HIV testing and treatment, especially for key populations. Applying self-testing to hepatitis C virus (HCV) may also offer an additional way to address low coverage of HCV testing and to accelerate elimination efforts. To understand the potential for HCV self-testing (HCVST), an observational study was conducted to assess the acceptability and usability of the OraQuick® HCV Self-Test (prototype) among people who inject drugs (PWID) and men who have sex with men (MSM) in Thai Nguyen, a province in northern Vietnam. A total of 105 PWID and 104 MSM were eligible and agreed to participate in the study. Acceptability, defined as the proportion of participants among eligible subjects who agreed to participate in the study, was 92.9% in PWID and 98.6% in MSM. Compared to MSM, PWID were older (median age: 45 vs. 22 years; p < 0.0001) and had a lower education level (high school and college: 38.1% vs. 100%; p < 0.0001). HCVST usability was high among MSM with fewer observed mistakes, difficulties, or participants requiring assistance (33.7%, 28.8%, and 17.3%, respectively) compared to PWID (62.9%, 53.3%, and 66.7%, respectively; all p < 0.0001)). Inter-reader and inter-operator agreement were good in both groups (Kappa coefficient range: 0.61–0.99). However, the concordance between HCVST and study staff -read or performed HCV testing was lower among PWID than MSM (inter-reader concordance 88.6% vs. 99.0% and inter-operator concordance 81.9% vs. 99%). Overall, HCVST was highly acceptable with moderate to high usability among PWID and MSM in Thai Nguyen. Efforts to provide support and assistance may be needed to optimize performance, particularly for PWID populations and for those who are older and with lower literacy or education levels.

Abstract:

Background. HIV continues to be a major concern among MSM, yet Black MSM have not been enrolled in HIV research studies in proportionate numbers to White MSM. We developed an HIV prevention research brand strategy for MSM. Methods. Questionnaires and focus groups were conducted with 54 participants. Descriptive statistics and chi-square analyses were performed and qualitative data were transcribed and content analyzed to identify common themes. Results. Formative research results indicated that younger Black MSM (18–29 years) were less likely to think about joining prevention studies compared to older (≥30 years) Black MSM (x2=5.92, P=0.015). Qualitative and quantitative results indicate four prominent themes related to brand development: (1) communication sources (message deliverer), (2) message (impact of public health messaging on perceptions of HIV research), (3) intended audience (underlying issues that influence personal relevance of HIV research), and (4) communication channels (reaching intended audiences). Conclusion. The findings highlight the importance of behavioral communication translational research to effectively engage hard-to-reach populations. Despite reservations, MSM in our formative study expressed a need for active involvement and greater education to facilitate their engagement in HIV prevention research. Thus, the brand concept of “InvolveMENt” emerged.

Abstract:

Older adults with HIV are at increased risk of late diagnosis. We aimed to explore the association between age and HIV testing rates in sexual health clinics in England using Public Health England data for 2009–2014. We investigated associations between attendee age and likelihood of HIV test offer, acceptance, and coverage. For each year, increasing age was associated with reduced likelihood of test offer (Rs −0.797 to −0.958, p < 0·01). Offer rates were highest for men who have sex with men (MSM), and lowest for heterosexual females (HSFs). HSFs had the greatest decline in offer rates with age (from 86.2% for age 25–29 to 52.1% for age 70+ in 2014). Odds ratios for test offer in 2014 for attendees aged 15–49 compared with attendees aged 50+ were 1.94 (95%CI: 1.88, 2.00) for heterosexual males (HSMs), 1.86 (95%CI: 1.81, 1.91) for HSFs, and 1.54 (95%CI: 1.45, 1.64) for MSM. Overall, there was no significant association between age and test acceptance in any year (Rs −0.070 to −0.547; p > 0·05). The strongest determinant of acceptance was sexual orientation; for attendees aged 50+, compared with HSMs, acceptance was higher for MSM (OR: 1.10; 95%CI: 1.06, 1.13) and lower for HSFs (OR: 0.30; 95%CI: 0.30, 0.31).

Abstract:

ObjectivesMen who have sex with men (MSM) are a highly neglected population in the current recommendation of girls-only human papillomavirus (HPV) vaccination programmes in many countries. To better assess the cost effectiveness of HPV vaccination among men requires data on the prevalence of HPV infection in MSM using a community sample, which is still sparse in several regions. We examined the prevalence of and factors associated with anogenital HPV infection among MSM in Taiwan.MethodsMSM 20 years of age and older were recruited from the community and social media in Taiwan in 2015–2016 and screened for HPV infection to detect 37 genotypes. MSM were seen at baseline and were/will be seen at 6, 12, 24 and 36 months. Men completed a questionnaire regarding their sexual experiences. Multivariable regression analyses were conducted to identify associated behavioural risk factors using the baseline data.ResultsA total of 253 MSM were recruited; 87 % were below 35 years of age. Diagnosis of HIV was reported in 4% of men; just over 20% had three or more anal sex partners in the past year. The prevalence of any tested HPV type was 29.4% at the anal site and 11% at the penile site. One quarter of MSM were infected with any of the 9-valent vaccine HPV types. Anal HPV detection was associated with having three or more receptive anal sex partners in the past year (adjusted odds ratio (aOR)=2.92, 95% CI 1.29 to 6.61) and having older sex partners (aOR=2.51, 95% CI 1.07 to 5.90).ConclusionsOur data provide the base to calculate the reproductive rate for HPV transmission in a low-risk community sample and cost-effectiveness to include men in HPV vaccination policies. Adding evidence from a community sample adds comprehensiveness for future estimates of disease transmission and vaccine effectiveness.

Abstract:

ObjectiveIn 2017, there was an outbreak of invasive meningococcal disease (IMD) serogroup C among men who have sex with men (MSM) in Victoria, Australia. A government-funded free meningococcal (MenACWY) vaccination programme targeting all MSM living in Victoria was launched between December 2017 and December 2018. The aim of this study was to examine the vaccine uptake among MSM attending a sexual health clinic in Melbourne.MethodsThis was a retrospective clinical audit of MSM attending the Melbourne Sexual Health Centre (MSHC) during the vaccination programme. We calculated the proportion of MSM who received the meningococcal vaccine on their first visit and at any time during the programme. We performed univariable and multivariable logistic regression to identify the factors associated with the vaccine uptake on the first visit.ResultsOf the 10 370 MSM who attended MSHC, 55.5% received the vaccine on their first visit and 67.4% at any time during the programme. MSM had higher odds of receiving the vaccine on the first visit if they were aged 16–25 years (adjusted OR (aOR) 1.21; 95% CI 1.08 to 1.35) or 26–35 years (aOR 1.17; 95% CI 1.07 to 1.29) in comparison with MSM older than 35 years; were HIV-negative and not on pre-exposure prophylaxis (aOR 1.80; 95% CI 1.56 to 2.09); had more than four male partners in the last 12 months (aOR 1.16; 95% CI 1.06 to 1.27); had male partners only (aOR 2.24; 95% CI 1.96 to 2.55); or were born overseas (aOR 1.11; 95% CI 1.03 to 1.21).ConclusionsTwo-thirds of the MSM attending a sexual health clinic received at least one dose of meningococcal vaccine. The vaccination programme coincided temporally with a dramatic reduction in the incidence of IMD. Vaccination should be further promoted among MSM and men who have sex with both men and women.

Abstract:

Purpose The purpose of this paper is to examine patterns of drug use among a cohort of drug treatment-seeking drug-using gay men and other men who have sex with men (MSM), and whether these activities differ between, or predict, HIV status. Design/methodology/approach Cross-sectional study was conducted in a specialist club drug clinic in London covering 407 consecutive attendees who identified as MSM. Substance use, including injecting drug use (IDU), associated sexual activity and self-reported HIV status were measured by clinical interview and National Drug Treatment Monitoring System data tool. Findings Over a 45-month period, 407 MSM attended the clinic. In total, 62.1 per cent were HIV positive, 48.9 per cent had injected drugs, 14.9 per cent reported needle sharing and 73.3 per cent used drugs to facilitate sex. The most commonly reported problem drugs were GHB/GBL (54.3 per cent) methamphetamine (47.7 per cent) and mephedrone (37.8 per cent). HIV status was associated with methamphetamine, mephedrone, IDU, sharing equipment, using drugs to facilitate sex, older age and older age of drug initiation, as well as Hepatitis C virology (HCV) status. Use of methamphetamine, HCV infection, older age and IDU predicted HIV positive status in a logistic regression model. Practical implications The findings describe a constellation of risk factors including high levels of IDU, sharing of equipment and high-risk sexual activity in a population with high rates of HIV positive serology. They also provide further evidence for a link between HIV infection and use of methamphetamine. Social implications The authors suggest a need for greater awareness of HIV-related risk activities and promotion of HIV prevention strategies for MSM by both sexual health and drug treatment services. Originality/value This paper is amongst the very first studies of its nature.

Abstract:

Routine HIV surveillance cannot distinguish between recent and older infections: HIV-positive individuals reported soon or long after infection are both considered new diagnoses from a surveillance perspective, notwithstanding the time since infection. This lack of specificity makes it difficult to understand the jurisdiction-specific trends in HIV epidemiology needed for prevention planning. Previous efforts have been made to discern such timing of infection, but these methodologies are not easily applied in a public health setting. We wished to develop a simple protocol, using routinely collected information, to classify newly diagnosed infections as recent or older, and to enumerate and characterize recent versus older infections. Applying our methodology to a review of HIV cases reported between January 2011 and December 2014, we classified 62% of cases; one-third of these were recent infections. Although men who have sex with men (MSM) and persons from HIV-endemic countries (HEC) disproportionally accounted for new HIV diagnoses, the dynamics of HIV transmission within these groups differed dramatically: MSM accounted for the majority of recent infections, whereas persons from HEC accounted for the majority of older infections. Among older infections, one-quarter were previously unaware of their infection. Categorizing cases in this manner yielded greater, jurisdiction-specific understanding of HIV, and guides subpopulation-specific interventions.

Abstract:

Abstract Background and Objectives Conversion therapies to minimize same-sex attractions are classified as a dangerous practice by numerous scientific institutions in the United States. These practices may contribute to poor long-term psychosocial health, thereby interrupting processes of healthy aging. Few studies have examined psychosocial differences between persons with and without prior experiences of conversion therapy. We assessed associations between prior conversion therapy experiences and psychosocial health among midlife and older men who have sex with men (MSM; age 40+ years). Research Design and Methods Participants included a multicity sample of MSM (N = 1,156) enrolled in the Multicenter AIDS Cohort Study who completed health surveys (2016–2019) as part of their biannual study visits. Using multivariable regressions, we investigated the associations of prior conversion therapy with current depressive symptoms, internalized hom*ophobia, post-traumatic stress, and cumulative psychosocial conditions. Using a trait-level measure (e.g., life purpose and perseverance), we tested whether resilience moderated these associations. Results The full sample was predominantly non-Hispanic white with a mean age of 62.6 years. Fifteen percent of men (n = 171/1,156) reported prior conversion therapy. In multivariable models, men exposed to conversion therapy were more likely to have depressive symptoms and above-average internalized hom*ophobia. Men exposed to conversion therapy had 2–2.5 times the odds of reporting 1 and ≥2 psychosocial conditions, respectively, compared with those who reported 0 conditions. Resilience did not moderate these associations. Discussion and Implications Conversion therapies are nonaffirming social stressors for MSM and may compromise critical psychosocial aspects of healthy aging among MSM.

Abstract:

ObjectivesTo assess trends in sexual health outcomes among men who have sex with men (MSM) disaggregated by ethnicity.DesignRepeated cross-sectional.SettingBehavioural surveillance data from 2006, 2008, 2011 and 2014 were collected in-person and online across Aotearoa New Zealand.ParticipantsEligible participants were self-identified men aged 16 years or older who reported sex with another man in the past 5 years. We classified 10 525 participants’ ethnicities: Asian (n=1003, 9.8%), Māori (Indigenous people of Aotearoa New Zealand, n=1058, 10.3%), Pacific (n=424, 4.1%) and European (n=7867, 76.8%).Outcome measuresThe sexual health outcomes examined were >20 recent (past 6 months) male sexual partners, past-year sexually transmitted infection (STI) testing, past-year STI diagnosis, lifetime and past-year HIV testing, lifetime HIV-positive diagnosis and any recent (past 6 months) condomless anal intercourse with casual or regular partners.ResultsWhen disaggregated, Indigenous and ethnic minority groups reported sexual health trends that diverged from the European MSM and each other. For example, Asian MSM increased lifetime HIV testing (adjusted OR, AOR=1.31 per survey cycle, 95% CI 1.17 to 1.47) and recent HIV testing (AOR=1.14, 95% CI 1.02 to 1.28) with no changes among Māori MSM or Pacific MSM. Condomless anal intercourse with casual partners increased among Māori MSM (AOR=1.13, 95% CI 1.01 to 1.28) with no changes for Asian or Pacific MSM. Condomless anal intercourse with regular partners decreased among Pacific MSM (AOR=0.83, 95% CI 0.69 to 0.99) with no changes for Asian or Māori MSM.ConclusionsPopulation-level trends were driven by European MSM, masking important differences for Indigenous and ethnic minority sub-groups. Surveillance data disaggregated by ethnicity highlight inequities in sexual health service access and prevention uptake. Future research should collect, analyse and report disaggregated data by ethnicity to advance health equity.

Abstract:

Abstract In 1984, the Multicenter AIDS Cohort Study (MACS) was started to identify factors in the HIV epidemic related to disease risk and treatment progression among gay, bisexual, and other men who have sex with men (MSM) in four urban areas in the US: Baltimore, MD/Washington, D.C.; Chicago, IL; Pittsburgh, PA, and Los Angeles, CA. MACS participants complete biannual study visits involving HIV testing, biometric screenings, and psychosocial data collection. In 2015 a MACS sub-study, the Understanding Patterns of Healthy Aging among MSM Project (HAMSM), was started to better understand resiliencies promoting well-being among MSM age 40 and older, including those with HIV. HAMSM has helped us to understand aging trajectories among MSM, and provides a unique combination of physiological and psychosocial data that can inform efforts to support MSM in healthy aging. This symposium will present emerging findings from the HAMSM study. Our first paper examines the relationships between psychological connection to the gay community (PSOC) and developmental regulatory strategies associated with health behaviors and more positive self-appraisals. The second paper examines how PSOC is related to HIV risk reduction behaviors, and if there are differences in such behaviors based on HIV status. Our third paper considers how self-perceptions of aging (age discrepancy, aging satisfaction) are related to frailty and frailty transitions, and if these relationships differ by HIV status. The final paper examines the relationship of social support to frailty among MSM by HIV status. Implications of these findings for research, policy, and programs targeting MSM will be discussed.

Abstract:

Background Recent studies in Puerto Rico (PR) have reported an increasing incidence of anal cancer in Puerto Rican men. The objective of this study was to determine the prevalence, genotype distribution and risk factors associated with anal HPV infection among heterosexual men and men who have sex with men (MSM) attending an STI clinic in PR. Methods: We conducted a cross-sectional study of men 18 years and older. A comprehensive survey was administered that included a demographic and behavioural assessment. Logistic regression was performed to determine factors associated with any, high-risk (HR), low-risk (LR) and multiple anal HPV infection. Results: The mean age of the study sample was 38.0 ± 13.5 and 37.7 ± 13.0 years for MSM and heterosexual men, respectively. A third (29.8%) of the study sample reported being MSM. Significant differences were observed in the prevalence of any anal HPV infection for MSM (84.5%) as compared with heterosexual men (45.7%; P < 0.001). Although MSM showed a higher prevalence of both HR and LR HPV types, no significant differences were observed in the bivariate analysis. Overall, HR anal HPV infection was found in 58.5% of the participants. The most common HR types were 53, 58, 68, 51 and 31. Multiple HPV types in the anal canal were found in 50.0% of the sample. Multivariate logistic regression analysis showed that being a MSM was associated with any anal HPV infection (OR = 6.2; 95% CI 1.5, 25.7). Conclusions: Anal HPV is common among sexually active men attending this STI clinic, with a higher likelihood of any anal HPV infection among MSM.

Abstract:

The majority of those infected and affected by HIV are younger adults. The ability of highly active antiretroviral therapies (HAART) to extend survival means that those infected when younger may reach older age, and future increases in numbers of older individuals living with HIV in England, Wales and Northern Ireland (E,W&NI) are expected. Evidence that older individuals engage in risky sexual behaviours suggests potential for HIV transmission. Data from national HIV/AIDS surveillance systems were reviewed (1997–2001). An older individual is defined as aged 45 years or over. Between 1997 and 2001, 2290 older individuals were diagnosed with HIV; 361 in 1997, rising to 648 in 2001. Heterosexual acquisition accounted for 1073 (47%) infections; 662 were male. Where reported, 666 (65%) older heterosexuals were probably infected in Africa, 144 (14%) in the United Kingdom and 113 (11%) in Asia. There were 1020 (45%) new diagnoses acquired hom*osexually; white (92%), infected in the United Kingdom (78%). Numbers of older individuals accessing HIV-related services more than doubled between 1997 (2488) and 2001 (5175). In 2001, 2270 (53%) were London residents. Between 1997 and 2001, among HIV-infected older individuals attending genitourinary medicine (GUM) clinics, the proportions previously undiagnosed were 60% and 82% in heterosexual males and females respectively, and for men who have sex with men (MSM), 42%. Numbers of older individuals newly diagnosed with HIV have increased in recent years. The increase in numbers of older individuals accessing HIV-related services were in excess of younger adults. A significant proportion of older HIV-infected female heterosexuals and MSM were undiagnosed. Awareness must be raised among clinicians, and an ‘aged response’ to HIV is required.

Abstract:

HIV prevention research among men who have sex with men (MSM) has traditionally focused on individual risk reduction strategies. Our study evaluated awareness, utilization, and preferences for 10 complementary HIV prevention strategies among 1,286 MSM recruited via Facebook and Instagram from June-August 2018. Ages ranged from 18-85 years, and the majority were non-Hispanic white (n = 1,019, 79.24%), college-educated (n = 819, 63.69%), gay-identifying (n = 1,074, 83.51%), and partnered (n = 808, 62.83%). Post-exposure prophylaxis was the least familiar option, and engaging in sexual activities other than anal sex was the most utilized option. Progressively older and bisexual-identifying MSM were less likely, but those with higher educational levels and easy access to local HIV resources were more likely to be aware of and to be utilizing a greater number of strategies. Additionally, Hispanic MSM were less likely to be aware of, and those in a “closed” relationship were less likely to be utilizing a greater number of strategies. In a subset of 775 multiple strategy users, pre-exposure prophylaxis, regularly testing for HIV, and limiting the number of sex partners emerged as the most preferred options. Combination intervention packages for MSM should be tailored to personal circ*mstances, including sexual orientation, relationship characteristics and access to local HIV resources.

Abstract:

Abstract Background Little is known about the impact of psychosocial factors and substance use on viral suppression among human immunodeficiency virus (HIV)–infected key populations in resource-limited settings. Accordingly, we examined the association and interactions between depression, alcohol use, and recreational drug use on viral suppression among men who have sex with men (MSM) and people who inject drugs (PWID) in India. Methods MSM and PWID were recruited across India using respondent-driven sampling (RDS). Correlates of viral suppression were determined using Poisson regression models incorporating RDS-II weights. Two-way multiplicative interactions were assessed with separate models of all combinations of the 3 variables of interest using interaction terms; 3-way interactions were evaluated by stratifying 2-way interactions by the third variable. Results Among 1454 treatment-eligible HIV-infected MSM and 1939 PWID, older age (adjusted prevalence ratio [aPR], 1.14 for MSM; 1.41 for PWID) and higher HIV treatment literacy (aPR, 1.58 for MSM; 3.04 for PWID) were positively associated with viral suppression. Among MSM, there was evidence of a synergistic negative association between severe depression and recreational drug use (aPR, 0.37 [95% confidence interval {CI}, .16–.84]), alcohol dependence and recreational drug use (aPR, 0.45 [95% CI, .20–.99]), and severe depression, alcohol dependence, and recreational drug use (aPR, 0.23 [95% CI, .09–.57]). Among PWID, daily injection (aPR, 0.51 [95% CI, .31–.82]) was the primary barrier to suppression. Conclusions Incorporating psychosocial and harm-reduction services into differentiated care models targeting MSM and PWID in low-resource settings is critical to achieving the 90-90-90 HIV/AIDS targets.

Abstract:

Abstract Men who have sex with men (MSM) report greater body dissatisfaction compared with heterosexual men, which increases with age. This may result from internalized gay community values regarding ideal physiques and youth. Using structural equation modeling, we examined these relationships among 1,118 MSM men age 40 and older from the Healthy Aging Study (M age=59.9 years/50.1% HIV+/69.8% non-Hispanic White). We hypothesized gay community attachment would be related to self-appraisals (body dissatisfaction/internalized ageism), and that this relationship would be mediated by developmental regulation strategies (physical activity/exercise intentions). The model fit the data well (RMSEA = .048, 90% CI 0.017-0.079). Contrary to our hypothesis, connection to the gay community was related to positive self-appraisals (-.40, p&lt;.001), with significant indirect effects via regulation strategies (-.12, p&lt;.002). Thus, gay community connections are related to positive self-appraisals in older GB men and enhance strategies supporting physical and psychological health. Implications for practice will be discussed.

Abstract:

Objective: The objective of our study was to assess meningococcal ACWY (MenACWY) vaccine uptake among men who have sex with men (MSM) during an ongoing, invasive meningococcal disease outbreak in Southern California. This research was important to inform future vaccination uptake interventions for this high-priority population. Methods: We conducted venue-based sampling to recruit and enroll MSM living in Los Angeles County, California, from December 2016 through February 2017. We conducted bivariate and multivariable analyses to evaluate associations between MenACWY vaccine uptake and other predetermined factors. Results: Of 368 participants, 138 (37.5%) reported receiving the MenACWY vaccine. In multivariable analyses, older age (adjusted odds ratio [aOR] = 2.57; 95% confidence interval [CI], 1.31-5.03), previous diagnosis of a sexually transmitted infection (aOR = 2.22; 95% CI, 1.14-4.30), belief that MenACWY vaccine is important (aOR = 3.49; 95% CI, 1.79-6.82), confidence in the MenACWY vaccine (aOR = 5.53; 95% CI, 3.11-9.83), and knowing someone who had been vaccinated (aOR = 5.82; 95% CI, 3.05-11.12) were significantly associated with MenACWY vaccine uptake. Conclusions: Our findings reflect low uptake of the recommended MenACWY vaccine among MSM after a local outbreak, despite public health efforts. In addition to ongoing, widespread campaigns to inform MSM about local outbreaks and vaccination recommendations, MSM may be responsive to direct outreach from peers who have been vaccinated.

Abstract:

This pilot study examined the feasibility and acceptability of the HIV/AIDS self-management education program-Thai (HASMEP-T) for HIV-positive Thai men who have sex with men (MSM). HASMEP-T is a group-based adaptation of the evidence-based intervention, HASMEP. Participants were 40 Thai MSM living with HIV aged 18 years or older, recruited from an HIV clinic housed in a hospital in Thailand. Results support the feasibility of recruitment, screening, eligibility, and retention methods. The majority of the participants reported that the intervention was acceptable and met their initial expectations. Furthermore, all recruited participants in the intervention group (n = 20) completed HASMEP-T. Overall, intervention group participants demonstrated significant increases in all aspects of HIV self-management (p < .05), as well as improvement in quality of life in the psychological domain (p < .05). Our findings provide preliminary support for the large-scale, randomized-controlled trial of the efficacy of HASMEPT to promote self-management behaviors among HIV-positive Thai MSM.

Abstract:

Abstract Background Pre-Exposure Prophylaxis (PrEP) effectively prevents HIV acquisition in men who have sex with men (MSM), if taken appropriately. Effective PrEP requires persistence in PrEP care. We defined the PrEP care continuum in a Deep South PrEP clinic and examined factors related to persistence in care among MSM. Methods We reviewed data for MSM at a university-affiliated PrEP clinic in Birmingham, AL from 2014–2018 to define the PrEP continuum at five major steps: screening, initial visit, follow-up visit, current persistence, and self-reported adherence. We defined persistence as attending a PrEP clinic visit in the last 6 months and nonpersistence as prior attendance without a visit in the last 6 months. We compared demographics, insurance status, and patient-reported behaviors from initial and most recent visits between those who persisted (“persisters”) and did not (“non-persisters”) using Wilcoxon rank sum, chi-square, or Fisher’s exact test. Results 226 (100%) MSM were screened, 141 (62%) MSM attended an initial visit, 116 (51%) MSM attended follow-up, 43 (19.0%) persisted in PrEP care, and 29 (13%) MSM self-reported good adherence (figure). Among 139 MSM (46 persisters, 93 nonpersisters), persisters were older than nonpersisters (33 vs. 32 yr, P = 0.03), and were less likely to report inconsistent condom use at their initial visit (48% vs. 73%; P = 0.01) as compared with their last visit (69% vs. 63%, P = 0.13). 23% of persisters and 29% of nonpersisters were black (P = 0.39), and 98% of persisters and 90% of nonpersisters were insured (P = 0.50). 60% of persisters and 74% of nonpersisters had multiple sex partners at initial visit (P = 0.19) as compared with 56% and 60% at their last visit, respectively (P = 0.83). Conclusion At a Deep South PrEP clinic, persistence overall was poor for MSM. More nonpersisters had inconsistent condom use, indicating higher risk despite nonpersistence. Although not statistically significant, nonpersisters were more likely to be black, uninsured, and have multiple sexual partners when compared with persisters. Disparities seen nationally in new HIV diagnoses are reflected in nonpersisters. Nonpersisters may not realize the extent of their risk of HIV acquisition and warrant intensive engagement interventions. Disclosures All authors: No reported disclosures.

Abstract:

Background With society ageing, sexually transmissible infections (STIs) in the older population are of interest from an economic, health-related and social burden perspective. Few studies on STIs in men older than 60 years of age exist. Methods: A retrospective study was performed looking at characteristics of, and STIs in, 29 106 men (of which 689 were older than 60 years of age), at first presentation, visiting the only South Australian public sexually transmitted diseases (STD) clinic over a 13-year period. Results: Older men [men who have sex with men (MSM) and men who have sex with women (MSW)] were less likely than younger men to have been tested for HIV. Conclusion: There is a need for increased HIV testing in older men.

Abstract:

Men who have sex with men (MSM) and purchase sex (MPS) are a sub-group potentially at high risk for acquiring and transmitting sexually transmitted infections (STIs). This is a hard-to-reach population resulting in a scarcity of studies covering the issue. This cross-sectional study aimed to assess the association between purchasing sex and high-risk behaviors related to HIV/STI transmission and appraise the STI prevalence among MSM. All MSM who attended the STI clinic in Tel Aviv between 2003 and 2010 were included. Demographics, behavioral, clinical, and laboratory data were compared between MPS and non-MPS to identify high-risk sexual behaviors and STI prevalence associated with purchasing sex. Of the first visits of 2694 MSM who attended the STI clinic during the study period, 151 (5.6%) paid for sex. MPS were more commonly older and married than non-MPS. MPS were more likely to engage in behaviors associated with high risk for HIV/STI transmission, including infrequent condom use during anal sex, substance use during sex, and selling sex themselves. MPS had a higher STI prevalence than non-MPS, although this was not statistically significant ( p = 0.05). These findings highlight the need to establish culturally tailored interventions for MPS addressing the potential risks associated with purchasing sex.

Abstract:

ObjectivesDespite a recent fall in the incidence of HIV within the UK, men who have sex with men (MSM) continue to be disproportionately affected. As biomedical prevention technologies including pre-exposure prophylaxis are increasingly taken up to reduce transmission, the role of HIV testing has become central to the management of risk. Against a background of lower testing rates among older MSM, this study aimed to identify age-related factors influencing recent (≤12 months) HIV testing.MethodsCross-sectional subpopulation data from an online survey of sexually active MSM in the Celtic nations—Scotland, Wales, Northern Ireland and Ireland (n=2436)—were analysed to compare demographic, behavioural and sociocultural factors influencing HIV testing between MSM aged 16–25 (n=447), 26–45 (n=1092) and ≥46 (n=897).ResultsMultivariate logistic regression demonstrated that for men aged ≥46, not identifying as gay (OR 0.62, CI 0.41 to 0.95), location (Wales) (OR 0.49, CI 0.32 to 0.76) and scoring higher on the personalised Stigma Scale (OR 0.97, CI 0.94 to 1.00) significantly reduced the odds for HIV testing in the preceding year. Men aged 26–45 who did not identify as gay (OR 0.61, CI 0.41 to 0.92) were also significantly less likely to have recently tested for HIV. For men aged 16–25, not having a degree (OR 0.48, CI 0.29 to 0.79), location (Republic of Ireland) (OR 0.55, CI 0.30 to 1.00) and scoring higher on emotional competence (OR 0.57, CI 0.42 to 0.77) were also significantly associated with not having recently tested for HIV.ConclusionKey differences in age-related factors influencing HIV testing suggest health improvement interventions should accommodate the wide diversities among MSM populations across the life course. Future research should seek to identify barriers and enablers to HIV testing among the oldest and youngest MSM, with specific focus on education and stigma.

Abstract:

Background: Men who have sex with men (MSM) remain the group most affected by the HIV epidemic in the United States. At least one-quarter of MSM report engagement in group sex events (GSEs), which can pose a risk for HIV transmission and acquisition. In this study, identification of event-level correlates of sexual and drug use behaviours at GSEs was sought to better inform prevention activities. Methods: For this study, participants were recruited via banner and pop-up advertisem*nts placed on a geosocial networking mobile phone application that MSM use to meet men. Results: Of the 1997 individuals who completed the study screener, 36.0% reported participating in at least one GSE in the prior year. In multivariable logistic regression analysis, attendance at a GSE in the past year was significantly associated with older age, full/part time employment and being HIV positive. Of the men who attended a GSE, more than half reported condomless anal sex (CAS) with at least one of their partners (insertive: 57.7%; receptive: 56.3%). MSM who indicated drug use had significantly higher odds of having insertive CAS [odds ratio (OR) = 2.45; 95% confidence interval (CI): 1.37–4.39] and receptive CAS (OR = 3.60; 95% CI: 1.96–6.63) at their last GSE. Conclusions: The high prevalence of HIV-positive MSM engaging in group sex, coupled with their greater odds of CAS, poses a significant risk for HIV/STI transmission within the group sex setting. More research is needed to determine patterns of condom use at these events and whether seroadaptive behaviours are driving CAS.

Abstract:

Hypertension affects nearly a third of U.S. adult males and is a leading risk factor for cardiovascular disease, but there is a paucity of hypertension research among men who have sex with men (MSM). Andersen’s model of health service use was adapted to examine factors associated with hypertension among MSM. In 2008, 7,454 U.S. MSM completed an online survey. Overall, 16.5% of the sample reported a lifetime diagnosis of hypertension. In hierarchical logistic regression, Black MSM had increased odds of reporting hypertension (adjusted odds ratio [AOR] = 1.79, 95% confidence interval [CI] [1.24, 2.60]) compared with White MSM, as did men aged 30 years and older (age 30-39: AOR = 2.46, 95% CI [1.84, 3.29]; age 40-49: AOR = 3.76, 95% CI [2.85, 4.97]; age 50+: AOR = 6.40, 95% CI [4.78, 8.58]; Reference: 18-29 years). Health conditions associated with hypertension included diabetes (AOR = 3.62, 95% CI [2.81, 4.68]), heart disease (AOR = 5.19, 95% CI [3.99, 6.75]), depression (AOR = 1.38, 95% CI [1.17, 1.63]), anxiety (AOR = 1.30, 95% CI [1.09, 1.57]), and being overweight (AOR = 2.23, 95% CI [1.91, 2.59]). Having a primary care provider (AOR = 2.19, 95% CI [1.64, 2.93]) and residing in South Atlantic (AOR = 1.39, 95% CI [1.12, 1.74]) or South Central (AOR = 1.59, 95% CI [1.27, 2.00]) regions was also associated with reporting hypertension. Study findings are consistent with those in the literature for the general population. To address health care inequities, the Internet could serve as a potential access point for health screening and referral for care.

Abstract:

Background HIV prevalence has been rapidly increasing among men who have sex with men (MSM) attending university in China, but HIV testing rates remain suboptimal. The factors associated with past HIV testing in this population in Beijing, China, were investigated. Methods: This study used data from the baseline survey of an HIV intervention clinical trial among MSM who did not have a history of a positive HIV diagnosis. This analysis focused on the HIV testing experience in a subgroup of university student MSM participants. Log-binomial models were used to evaluate factors associated with past HIV testing. Results: Of 375 university student MSM, the median age was 22 years; 89.3% were Han ethnic. Approximately half (50.4%, n = 189) had ever taken an HIV test before the survey. In a multivariable log-binomial model, older age (adjusted prevalence ratio (APR), 1.04; 95% confidence interval (CI), 1.02–1.06), had first sexual intercourse at age &lt;18 years (APR, 1.35; 95% CI, 1.08–1.45) and knew someone living with HIV (APR, 1.33; 95% CI, 1.07–1.61) were associated with a higher likelihood of past testing. Self-reported barriers to taking a test included perceived low HIV risk, fear of a positive diagnosis, did not know where to get tested and fear of discrimination. Facilitators included anonymity in taking a test, confidentiality of testing results and availability of home-based and rapid testing. Conclusions: The HIV testing rate among university student MSM was low. Interventions should be implemented to address structural, institutional and individual barriers to HIV testing in this vulnerable population.

Abstract:

Gay dating applications (apps) are popular among men who have sex with men (MSM) in China. This study examined the relationship between gay dating app use frequency and condomless anal intercourse (CAI) in a sample of MSM in Beijing. In October 2017, a web-based, cross-sectional survey was conducted among MSM from Beijing, China. Demographics, frequency of app use, and sexual behaviors were collected and analyzed. Multivariable logistic regression and restricted cubic splines were used to evaluate the association between app use frequency and CAI. Of the 9280 participants, the proportion of CAI within one month prior to the survey was 43.3%, and 43.7% logged onto the app ≥11 times per week. In adjusted logistic regression analysis, logging onto the app 6–10 times per week and ≥11 times per week were inversely associated with CAI (adjusted odds ratio [AOR] =0.88 [95%CI, 0.78–0.99]; AOR = 0.88 [95%CI, 0.82–0.97], respectively). Among those 40 years of age or older, logging onto the app ≥11 times per week was associated with lower rates of CAI (AOR = 0.57 [95%CI, 0.40–0.81]). Results indicate that frequent app use was associated with lower odds of CAI among MSM in Beijing, China. Innovative interventions, which take advantage of this popular media platform, should be developed as such apps have been found to reduce the odds of CAI in Beijing.

Abstract:

Background and purpose: Transmission of HIV and other sexually transmitted infections (STIs) among men who have sex with men (MSM) in Bali Province is increasing. This increased transmission is due to their sexual networks and behaviours. This study aims to examine sexual behaviours and sexual networks among MSM population in Bali Province. Methods: A descriptive cross-sectional study was conducted in Denpasar City and Badung District. A total of 130 MSM were recruited from Denpasar II Public Health Centre and Bali Medica Clinic – Badung District. Data were collected through interviews among MSM who visited both providers for STIs services from August to October 2015. Variables of this study included sociodemographic, sexual network (pattern and density), sexual activities in the last month, sexual role, condom/lubricant use, and history of previous STIs. Data were descriptively analysed. Results: As many as 53.1% respondents were aged <25 years, 90.8% were senior high school or higher degree graduates, 6.2% were married, 91.5% were employed, and 59.2% were having a regular partner. In the last month, as many as 70.8% respondents reported to have sex with first sexual partner, 52.3% with second sexual partners, and 45.6% with third sexual partners. Younger respondents tended to seek for younger sexual partners. The majority of respondents had had insertive sex, as many as 40.0% with their first partner, 44.6% with their second partner, and 43.2% with their third partner. About 20% of respondents were having high density sexual network and 71.5% of respondents were having concurrent sexual partnership. The consistent condom use within six months was 67.6% with the first partner, 72.8% with the second and the third partners. As many as 23% of respondents were diagnosed to have STIs. Conclusion: MSM population in Bali Province seem to have high risk sexual behaviours with great sexual network density, high concurrent sexual partnership, and selective mixing between older and younger MSM population.

Abstract:

BackgroundOutbreaks of hepatitis A are being reported more commonly among men who have sex with men (MSM) globally. Australia has also reported a sharp increase in the number of cases of hepatitis A in 2017. This study aimed to determine the level of immunity to hepatitis A among MSM attending a large urban sexual health clinic in Victoria in the lead up to recent outbreak.MethodsThis was a retrospective audit of serological testing data from first-time MSM attendees at Melbourne Sexual Health Centre (MSHC) in Australia from 1 January 2012 to 31 December 2018. We determined the proportion of MSM who were tested and who had serological detection of hepatitis A IgG, stratified by age and calendar year. We used univariable and multivariable logistic regression to investigate factors associated with testing for and detection of hepatitis A IgG.ResultsThere were 16 609 first-time MSM attendees at MSHC over the 7-year period, of which 9718 (59%, 95% CI 58% to 60%) were tested for hepatitis A IgG. There was a 2% annual increase in the proportion of men tested (from 60% in 2012 to 69% in 2018; OR=1.02, 95% CI 1.00 to 1.03, p=0.025). Men born outside of Australia/New Zealand, and younger men <30 years had higher odds of being tested. Of those tested, 44% (n=4304, 95% CI 43% to 45%) had hepatitis A IgG detected at their first visit, with no change over time (OR=1.01, 95% CI 0.99 to 1.03, p=0.210). Detection of hepatitis A IgG was associated with being aged 30 years or older (adjusted OR=2.06, 95% CI 1.89 to 2.24, p<0.001) or being born overseas versus Australia/New Zealand (AOR=1.21, 95% CI 1.11 to 1.31, p<0.001).ConclusionHepatitis A immunity among MSM remains below the estimated 70% required to prevent outbreaks. Measures including increased testing and higher vaccination coverage are needed to prevent outbreaks and to limit the number of cases and deaths.

Abstract:

ObjectivesOver the last 15 years, the prevalence of HIV in Haiti has stabilised to around 2.0%. However, key populations remain at higher risk of contracting HIV and other sexually transmitted infections (STIs). The prevalence of HIV is 12.9% among men having sex with men (MSM). There is limited information about the prevalence of other STI in the Haitian population in general and even less among key populations. We assessed the burden ofChlamydia trachomatis(CT) andNeisseria gonorrhoeae(NG) and risk factors for infections among MSM in Haiti.MethodsA cross-sectional study was conducted. MSM were recruited from seven health facilities in Port-au-Prince. All samples were tested by nucleic acid amplification test, using GeneXpert. A survey was administered to the participants to collect socio-demographic, clinical and risk behaviour data.ResultsA total of 216 MSM were recruited in the study. The prevalence rates of CT and NG were 11.1% and 16.2%, respectively. CT NG co-infections were found in 10/216 (4.6%) of the participants. There were 39 MSM with rectal STI compared with 17 with genital infections. Participants between 18–24 and 30–34 years old were significantly more likely to be infected with NG than those aged 35 years or older (OR: 22.96, 95% CI: 2.79 to 188.5; OR: 15.1, 95% CI: 1.68 to 135.4, respectively). Participants who never attended school or had some primary education were significantly more likely to be infected with NG than those with secondary education or higher (OR: 3.38, 95% CI: 1.26 to 9.07). People tested negative for HIV were significantly more likely to be infected with CT than people living with HIV/AIDS (OR: 3.91, 95% CI: 1.37 to 11.2).ConclusionsPeriodic risk assessment and testing for STI should be offered in Haiti as part of a comprehensive strategy to improve the sexual health of key populations.

Abstract:

Background: Stigma and discrimination are major challenges faced by people living with HIV (PLWH), and stigma continues to be prevalent among PLWH. We conducted a cross-sectional study of 584 men who have sex with men (MSM) living with HIV between July 2018 and December 2020, designed to better understand which demographic and behavioral characteristics of MSM living with HIV in San Francisco, California are associated with experience of stigma, so that programs and initiatives can be tailored appropriately to minimize HIV stigma’s impacts. Methods: This analysis was conducted with data from San Francisco AIDS Foundation (SFAF) encompassing services from multiple different locations in San Francisco. Data about the level of HIV-related stigma experienced were collected through a single question incorporated into programmatic data collection forms at SFAF as part of the client record stored in SFAF’s electronic health record. We performed linear regression to determine the associations between self-reported experiences of HIV stigma and other characteristics among MSM living with HIV. Results: HIV stigma was low overall among MSM living with HIV who are actively engaged in HIV care in San Francisco; however, it was significantly higher for the age groups of 13–29 years (adjusted risk difference (ARD): 0.251, 95% CI: 0.012, 0.489) and 30–49 years (ARD: 0.205, 95% CI: 0.042, 0.367) when compared to the age group of 50 years and older, as well as people who were homeless (ARD: 0.844, 95% CI: 0.120, 1.568), unstably housed (ARD: 0.326, 95% CI: 0.109, 0.543) and/or having mental health concerns (ARD: 0.309, 95% CI: 0.075, 0.544), controlling for race, injection history, and viral load. Conclusions: These findings highlight an opportunity to develop culturally, socially, and racially appropriate interventions to reduce HIV stigma among MSM living with HIV, particularly for younger men and those struggling with housing stability and/or mental health.

Abstract:

Scholars have noted that men who have sex with men (MSM) place value upon hegemonic masculinity, both in reference to the self as well as potential partners. The current study examined masculinity language, body language, and sports/working out language in MSM-specific mobile dating app profiles. Using selective self-presentation and self-categorization theory as a background, the current work uncovered a clear privileging of masculinity and a focus on the male body in participants’ profile language directed at the self and others. Men who used body language in their profiles were more likely to be older, single, and North American, while men who used sports/working out language were more likely to be college graduates from North America. Finally, the results indicated a connection between language regarding masculinity, the body, and sports/working out.

Abstract:

We analyzed men who have sex with men (MSM) from Denmark, Germany, Greece, Portugal and Spain to identify who would choose HIV self-testing as their preferred testing method and assessed their preferred setting to acquire a self-testing kit and to confirm a reactive result. In 2016, we recruited an online sample of 3725 HIV-negative MSM. We used Poisson regression to identify factors associated with choosing self-testing as the preferred testing option. For those choosing it as their preferred option, we assessed the preferred settings to acquire a self-testing kit and to confirm a reactive result. Not being open about one’s sexual behaviors with men was associated with choosing self-testing as the preferred option, except in Greece; older age in Greece and Spain; reporting condomless anal intercourses (CAI) in Germany and Portugal; reporting one previous test in Greece; between 2 and 5 in Spain and with having been tested ≥ 12 months ago in Germany, Portugal and Spain. The internet (32.8%) was the preferred place to acquire a self-testing kit and primary care (34.0%) for confirmation purposes. Self-testing was highly valued, especially among individuals who were not open about their sexual behaviors with men. In certain countries, it was also associated with older age, CAI and being undertested.

Abstract:

Abstract Background In the United States, human papillomavirus (HPV) vaccination has been recommended for young adult men who have sex with men (MSM) since 2011. Methods The Vaccine Impact in Men study surveyed MSM and transgender women aged 18–26 years in 3 US cities during 2016–2018. Self-collected anal swab and oral rinse specimens were assessed for 37 types of HPV. We compared HPV prevalence among vaccinated and unvaccinated participants and determined adjusted prevalence ratios (aPR) and 95% confidence intervals (CI). Results Among 1767 participants, 704 (39.8%) self-reported receiving HPV vaccine. Median age at vaccination (18.7 years) was older than age at first sex (15.7 years). Quadrivalent vaccine-type HPV was detected in anal or oral specimens from 475 (26.9%) participants. Vaccine-type HPV prevalence was lower among vaccinated (22.9%) compared with unvaccinated (31.6%) participants; aPR for those who initiated vaccination at age ≤18 years was 0.41 (CI, 0.24–0.57) and at age &gt;18 years was 0.82 (CI, 0.67–0.98). Vaccine effectiveness of at least 1 HPV vaccine dose at age ≤18 years or &gt;18 years was 59% and 18%, respectively. Conclusions Findings suggest real-world effectiveness of HPV vaccination among young adult MSM. This effect was stronger with younger age at vaccination.

Abstract:

Background: Long life expectancy in people living with human immunodeficiency virus (PLWH) caused an increase in comorbidities and co-medications. We aimed to analyse co-medications and drug-drug interactions (DDIs) in antiretroviral therapy (ART)-naive PLWH in the era of integrase inhibitors. Methods: A retrospective observational study was conducted between January 2016-August 2019. Patients’ characteristics and chronic co-medications were recorded. The university of Liverpool HIV drug interaction database was used for DDIs. Results: Among 745 patients, the chronic co-medication rate was 30.9%. Older age (p<0.001, OR:6.66, 95% CI: 3.86- 11.49) and female gender (p=002, OR:2.25, 95%:1.14-4.44) were independently associated with co-medication. Cardiovascular system (CVS) and central nervous system (CNS) drugs were most common co-medications. Older age (p<0.001, OR:12.04, 95% CI:4.63-36.71), having heterosexual (HS) contact (p=0.003, OR:3.8, 95% CI:1.57-9.22) were independently associated with CVS drugs use, while being men who have sex with men (MSM) (p=0.03, OR:2.59, 95% CI:1.11-6.03) was associated with CNS drugs use. DDIs were seen in 37.4% of patients with co-medications. Antidiabetics (23.3%), CNS (22.1%) and CVS drugs (19.8%) most commonly had DDIs. Contraindication was most commonly seen between inhaled corticosteroids and elvitegravir/cobicistat. A number of non-ART drugs, elvitegravir/cobicistat, antidiabetics, vitamins were independently associated with the presence of DDIs. Conclusion: Results suggested the need for attention about co-medication in PLWH regardless of whether they are young or older. CNS drugs should be questioned more detailed in MSM, as well as CVS drugs in older HS patients. Elvitegravir/cobicistat is significantly associated with DDIs and switching to an unboosted INSTI should be considered in patients with multiple comorbidities.

Abstract:

Background: Regular HIV testing means early detection of the virus and prompt access to treatment. However, factors affecting retesting following receipt of a non-reactive test result are not yet well understood. This study aims to determine the predictors of time to repeat HIV testing among men who have sex with men (MSM) from Metro Manila, Philippines within six months following receipt of a non-reactive test result. Methods: A prospective study was implemented at a community-based HIV testing and counseling center. A total of 250 non-reactive MSM from Metro Manila and with a recent risk of acquiring HIV were the respondents. At baseline, data on socio-demographic factors were gathered; while at follow-up, repeat test status of each participant within six months after baseline was collected. Results: Two retests per 1,000 person-weeks were recorded. Mean survival time was 23.93 weeks, 95% CI: [23.18 - 24.68]. Cox proportional hazards regression demonstrated that statistically significant factors of time to retest were age (HR = 0.90, 95% CI [0.85, 0.96]) and number of tests in lifetime (HR = 1.12, 95%CI [1.06, 1.18]). Conclusion: Although the average time to return is within the recommended period of three to six months, the low return rate suggests the call for encouraging repeat HIV testing among MSM with non-reactive results and recent risk of acquiring HIV. Repeat testing has been shown to be facilitated by age and previous testing history. HIV/AIDS counselors and program administrators can aim for MSM who are older and with relatively low testing history to help meet the global target of ending the HIV/AIDS global epidemic.

Abstract:

Since 2010, the Thailand Ministry of Public Health has recommended that men who have sex with men (MSM) have an HIV test at least two times a year. We calculated the proportion of, and factors associated with, testing adherence among the HIV-uninfected MSM clients attending Silom Community Clinic @TropMed. We defined testing adherence as repeating at least one HIV test within six months of an initial HIV-negative test, and used log-binomial regression to test for associated factors. We included 1927 clients during 2011–2014; 362 (19%) were adherent with an increased trend ( p < 0.01), from 16% to 24%. Clients aged 18–24 years and those having a history of HIV testing were more likely to adhere (aRR: 1.3, 95% CI: 1.1–1.6; and aRR: 1.3, 95% CI: 1.0–1.5, respectively). One-fifth adhered to the recommendation; older clients or naïve testees were less likely to adhere. We need to impress on clients the importance of repeat HIV testing.

Abstract:

In Jamaica, where hom*osexuality is criminalized, scant research has examined associations between sexual stigma and HIV infection. The study objective was to examine correlates of HIV infection among men who have sex with men (MSM) in Jamaica. We conducted a cross-sectional tablet-based survey with MSM in Jamaica using chain referral sampling. We assessed socio-demographic, individual, social, and structural factors associated with HIV infection. A logit-link model, fit using backwards-stepwise regression, was used to estimate a final multivariable model. Among 498 participants (median age: 24, interquartile range: 22–28), 67 (13.5%) were HIV-positive. In the multivariable model, HIV infection was associated with increased odds of socio-demographic (older age, odds ratio [OR]: 1.05, 95% confidence interval [CI]: 1.00–1.10]; residing in Kingston versus Ocho Rios [OR: 6.99, 95% CI 2.54–19.26]), individual (poor/fair versus excellent/good self-rated health [OR: 4.55, 95% CI: 1.81–11.42], sexually transmitted infection [STI] history [OR: 3.67, 95% CI: 1.61–8.38]), and structural (enacted sexual stigma [OR: 1.08, 95% CI: 1.01–1.15], having a health care provider [OR: 2.23, 95% CI: 1.06–4.66]) factors. This is among the first studies to demonstrate associations between sexual stigma and HIV infection in Jamaica. Findings underscore the need to integrate STI testing in the HIV care continuum and to address stigma and regional differences among MSM in Jamaica.

Abstract:

Introduction Despite a range of interventions, annual numbers of new diagnoses of HIV infection among men who have sex with men (MSM) in Australia have not declined in recent years. Peer-based sexual health clinics targeting MSM, such as the M Clinic in Perth (WA, Australia), have been put in place to provide safe sex counselling and to increase testing rates among MSM and who are at high risk of HIV infection. The aim of this study was to assess the incidence of HIV, chlamydia and gonorrhoea among men attending the M Clinic. Methods: This was a historical cohort study of repeated M Clinic clients from January 2011 to June 2015 inclusive. Testing and risk factor data from M Clinic client software were used to estimate the incidence of HIV, chlamydia and gonorrhoea and associated factors. Results: The incidence of HIV, chlamydia and gonorrhoea was 1.87, 13.58 and 6.48 per 100 person-years respectively. Older men had a higher incidence of HIV infection but a lower incidence of chlamydia and gonorrhoea than younger men. Conclusions: The HIV incidence was higher than found in similar studies in other Australian sexual health clinics, but the incidence of chlamydia and gonorrhoea was similar. The high HIV incidence among clients of the M Clinic points to the importance of making pre-exposure HIV prophylaxis available to clients of the M Clinic and similar services.

Abstract:

While studies on human immunodeficiency virus self-testing (HIVST) continue to accumulate after the World Health Organization’s recommendation of HIVST as an additional approach to HIV testing services in 2016, few studies have focused on men who have sex with men (MSM) in Chinese cities. A cross-sectional study was conducted to describe the HIVST status of MSM in Chongqing, China. MSM participants were recruited by random sampling, and qualified interviewers collected data, using confidential self-administered questionnaires. Blood specimens were collected for HIV antibody detection. The survey evaluated the uptake and accuracy of HIVST kits and identified factors that may be associated with HIVST. The proportion of HIVST uptake was 15.6%. The sensitivity and specificity of HIVST were 74.2% (95% confidence interval [CI] 66.6%–80.7%) and 99.0% (95% CI 96.9%–99.7%), respectively. The consistency between the HIVST kit and antibody detection results was 90.5% (95% CI 87.5%–93.0%), and the Kappa value was 0.777 (p < 0.001). The positive predictive value of self-testing kits is 80.9% and the negative predictive value is 17.7%. Having been tested ≥2 times in the last year, higher educational levels, and higher scores of basic HIV/AIDS knowledge facilitated higher uptake of HIVST. Self-reported existing barriers for HIVST uptake included older age, marital status, and having resided in Chongqing for more than two years.
