The question whether some men have a bisexual orientation-that is, whether they are substantially sexually aroused and attracted to both sexes-has remained controversial among both scientists and laypersons. Skeptics believe that male sexual orientation can only be homosexual or heterosexual, and that bisexual identification reflects nonsexual concerns, such as a desire to deemphasize homosexuality. Although most bisexual-identified men report that they are attracted to both men and women, self- ...[more]

Project description:BackgroundAmong gay, bisexual, and other men who have sex with men (GBM), sexual orientation disclosure to social groups can act as a significant risk for depression. The primary goal of this research is to understand the association between disclosure and depression, the association of social support and intimate partner violence (IPV) experiences, depression, and disclosure.MethodsThis project uses a secondary dataset of Thailand from a larger cross-sectional study distributed in the Greater Mekong Sub-Region. This study utilized web-based answers from 1468 Thai GBM respondents between the ages of 15-24 years.ResultsPrevalence of depression was over 50%. Across the social groups of interest, those who disclosed to everyone had the lowest depression prevalence. This association was statistically significant for all groups (p<0.050) except for "Family members" (p = 0.052). There was a statistically significant association illustrated between full disclosure to social groups and increased social support. Most respondents (43.9%) had low social support, and additionally this group had the highest level of depression, compared to those with high social support. There was a statistically significant association for lowered depression outcomes and increased social support. IPV experiences that occurred within the last six months had a statistically significant relationship with depression (p = 0.002). There was a notable association between those with experiences of being a victim of IPV, alone and in conjunction with experience of being a perpetrator of IPV, which was associated with increased odds of depression. However, the type of IPV experiences an individual had did not differ based on disclosure status.DiscussionThis study provides strengthened evidence of the impact that differences in supportive networks can have on mental health outcomes. In addition, they provided a wider consideration for how people may have different IPV experiences, either as a perpetrator, victim, or both, and how those shapes health outcomes of depression. GBM communities still face adversity and challenges that affect their long-term health outcomes, even if they do live in what is considered an accepting country.

Project description:A newly emergent literature suggest that bisexual men and women face profound health disparities in comparison to both heterosexual and homosexual individuals. Additionally, bisexual individuals often experience prejudice, stigma, and discrimination from both gay/lesbian and straight communities, termed "biphobia." However, only limited research exists that empirically tests the extent and predictors of this double discrimination. The Bisexualities: Indiana Attitudes Survey (BIAS) was developed to test associations between biphobia and sexual identity.Using standard techniques, we developed and administered a scale to a purposive online sample of adults from a wide range of social networking websites. We conducted exploratory factor analysis to refine scales assessing attitudes toward bisexual men and bisexual women, respectively. Using generalized linear modeling, we assessed relationships between BIAS scores and sexual identity, adjusting for covariates.Two separately gendered scales were developed, administered, and refined: BIAS-m (n=645), focusing on attitudes toward bisexual men; and BIAS-f (n=631), focusing on attitudes toward bisexual women. Across scales, sexual identity significantly predicted response variance. Lesbian/gay respondents had lower levels of bi-negative attitudes than their heterosexual counterparts (all p-values <.05); bisexual respondents had lower levels of bi-negative attitudes than their straight counterparts (all p-values <.001); and bisexual respondents had lower levels of bi-negative attitudes than their lesbian/gay counterparts (all p-values <.05). Within racial/ethnic minority respondents, biracial/multiracial status was associated with lower bi-negativity scores (all p-values <.05).This study provides important quantitative support for theories related to biphobia and double discrimination. Our findings provide strong evidence for understanding how stereotypes and stigma may lead to dramatic disparities in depression, anxiety, stress, and other health outcomes among bisexual individuals in comparison to their heterosexual and homosexual counterparts. Our results yield valuable data for informing social awareness and intervention efforts that aim to decrease bi-negative attitudes within both straight and gay/lesbian communities, with the ultimate goal of alleviating health disparities among bisexual men and women.

Project description:To assess the correlates for bisexual behaviors, HIV knowledge, and HIV/AIDS-related stigmatizing/discriminatory attitudes among men who have sex with men (MSM).A cross-sectional survey among MSM was conducted in 2011 to provide demographics, sexual behaviors, HIV knowledge, HIV/AIDS-related stigmatizing/discriminatory attitudes, and services in Jinan, Qingdao, and Yantai of Shandong Province of China.Of 1230 participants, 82.8% were single, 85.7% aged <35 years, and 47.2% received college or higher education. There were 28.6% MSM who reported to be married or cohabitating or ever had sex with woman in the past 6 months (P6M). 74.5% had ≥6 HIV-related knowledge score. The average total score of stigmatizing/discriminatory attitude was 37.4±4.4(standard deviation). Bisexual behavior was independently associated with higher levels of HIV/AIDS-related stigma/discrimination(AOR = 1.1, 95% CI:1.0-1.1), older age(AOR = 1.2, 95%CI:1.1-1.2), and lower HIV-related knowledge score(AOR = 1.6, 95%CI:1.2-2.2). HIV knowledge score ≥6 was independently associated with lower levels of HIV/AIDS-related stigma/discrimination(AOR = 1.3, 95%CI:1.2-1.3), less bisexual behaviors(AOR = 0.6, 95%CI:0.5-0.9), ever received a test for HIV in the past 12 months (P12M)(AOR = 3.2, 95%CI:2.3-4.5), college or higher level education(AOR = 1.9, 95%CI:1.4-2.6), consistent condom use with men in P6M(AOR=6.9, 95%CI:4.6-10.6), recruited from internet or HIV testing sites(AOR = 11.2, 95%CI:8.0-16.1) and bars, night clubs, or tea houses(AOR = 2.5, 95%CI:1.7-4.8). Expressing higher levels of HIV/AIDS-related stigmatizing/discriminatory attitudes was independently associated with bisexual behaviors(Aβ = 0.9, 95%CI:0.4-1.4), lower HIV-related knowledge score(Aβ = 3.6, 95%CI:3.0-4.1), the number of male sex partners in the past week ≥2(Aβ = 1.4, 95%CI:1.0-1.9), unprotected male anal sex in P6M(Aβ = 1.0, 95%CI:0.5-1.6), and inversely associated with ever received HIV test(Aβ = 1.4, 95%CI:0.8-2.0) and peer education in P12M(Aβ = 1.4, 95%CI:0.9-1.9).HIV/AIDS-related stigmatizing/discriminatory attitudes were associated with bisexual behaviors, low HIV testing rate, lower HIV-related knowledge and risk behaviors. This study called for innovative programs that would reduce HIV/AIDS-related stigmatizing/discriminatory attitudes and bisexual behaviors and improve the uptake of prevention service among MSM.

Project description:Initial research into seroadaptive strategies suggests that, individually, they are potentially effective behavioral methods to reduce risk of HIV transmission. Combining strategies, therefore, has the potential to increase risk reduction. The aim of this study was to determine how gay and bisexual men (GBM) combine strategies. To this end, a total of 774 sexually active GBM, aged ?16 years, in Metro Vancouver, Canada, were recruited. Grouped by self-reported HIV status, latent class analysis of self-reported condom use, strategic positioning, anal sex avoidance, serosorting, viral-load sorting, and withdrawal were conducted. Multinomial logistical regression identified explanatory variables of class membership (i.e., sensation seeking, treatment optimism, sexual altruism, relationship status, number of partners, anal sex preference). Four latent classes were identified: Condom Users, Multiple Prevention Users, Viral-Load Sorters, and Serosorters. The majority of HIV-negative/unknown men (72 %) and a large proportion of HIV-positive men (42 %) belonged to the Condom Users class. Class membership was associated with age, relationship status, treatment optimism, sexual altruism, sensation seeking, number of recent male anal sex partners, and recent condomless anal sex with a serodiscordant or unknown-status partner. Understanding these distinct patterns allows for tailored interventions addressing GBM's sexual health needs.

Project description:McKirnan's Cognitive Escape Theory (1996) is often characterized by the hypothesis that drugs are used during sex by gay, bisexual, and other men who have sex with men (gbMSM) to relieve internal cognitive conflict over safe-sex norms and sexual desire. We examined how McKirnan's Cognitive Escape Scale (CES) is related to other widely used constructs relevant to sexualized substance use with hopes of better situating the theory within the evolving landscape of HIV-prevention. Associations between CES and trait anxiety, depression, treatment optimism, sexual altruism, sexual sensation seeking, and self-perceived risk for HIV transmission/acquisition were tested. Mediation analyses tested whether associated psychological measures mediated the effect of CES on the proportion of events in which participants reported co-occurrent substance use and condomless anal sex. Results indicated that CES is associated with higher sexual sensation seeking, treatment optimism, trait anxiety, and perceived likelihood of HIV transmission/acquisition. Mediation analyses suggest that CES is related to but operates independently of treatment optimism, sensation seeking, and trait anxiety. Nevertheless, the intersection of HIV-related worries and substance use expectancies are clearly more nuanced than is widely reported is discussions on cognitive escape.

Project description:BackgroundGay, bisexual, and other cisgender men who have sex with men (GBMSM) are disproportionately affected by the HIV pandemic. Traditionally, GBMSM have been deemed less relevant in HIV epidemics in low- and middle-income settings where HIV epidemics are more generalized. This is due (in part) to how important population size estimates regarding the number of individuals who identify as GBMSM are to informing the development and monitoring of HIV prevention, treatment, and care programs and coverage. However, pervasive stigma and criminalization of same-sex practices and relationships provide a challenging environment for population enumeration, and these factors have been associated with implausibly low or absent size estimates of GBMSM, thereby limiting knowledge about the dynamics of HIV transmission and the implementation of programs addressing GBMSM.ObjectiveThis study leverages estimates of the number of members of a social app geared towards gay men (Hornet) and members of Facebook using self-reported relationship interests in men, men and women, and those with at least one reported same-sex interest. Results were categorized by country of residence to validate official size estimates of GBMSM in 13 countries across five continents.MethodsData were collected through the Hornet Gay Social Network and by using an a priori determined framework to estimate the numbers of Facebook members with interests associated with GBMSM in South Africa, Ghana, Nigeria, Senegal, Côte d'Ivoire, Mauritania, The Gambia, Lebanon, Thailand, Malaysia, Brazil, Ukraine, and the United States. These estimates were compared with the most recent Joint United Nations Programme on HIV/AIDS (UNAIDS) and national estimates across 143 countries.ResultsThe estimates that leveraged social media apps for the number of GBMSM across countries are consistently far higher than official UNAIDS estimates. Using Facebook, it is also feasible to assess the numbers of GBMSM aged 13-17 years, which demonstrate similar proportions to those of older men. There is greater consistency in Facebook estimates of GBMSM compared to UNAIDS-reported estimates across countries.ConclusionsThe ability to use social media for epidemiologic and HIV prevention, treatment, and care needs continues to improve. Here, a method leveraging different categories of same-sex interests on Facebook, combined with a specific gay-oriented app (Hornet), demonstrated significantly higher estimates than those officially reported. While there are biases in this approach, these data reinforce the need for multiple methods to be used to count the number of GBMSM (especially in more stigmatizing settings) to better inform mathematical models and the scale of HIV program coverage. Moreover, these estimates can inform programs for those aged 13-17 years; a group for which HIV incidence is the highest and HIV prevention program coverage, including the availability of pre-exposure prophylaxis (PrEP), is lowest. Taken together, these results highlight the potential for social media to provide comparable estimates of the number of GBMSM across a large range of countries, including some with no reported estimates.

Project description:BackgroundGay, bisexual and queer (GBQ) men are frequently subjected to minority stressors that have negative impacts on their health. Milestones that include the acceptance and disclosure of sexual identity amongst GBQ men are hence key instruments in understanding the prevalence of internalised homophobia and predicting health outcomes. As such, this work takes a novel approach to deduce the correlates of delayed acceptance of sexual orientation in young GBQ men as a measure of internalised homophobia through retrospective self-reporting and age-based analysis.MethodsParticipants were recruited as part of a cohort study exploring the syndemic risks associated with HIV acquisition among young GBQ men in Singapore. We examined their levels of internalised, perceived, experienced homophobia, as well as their health behaviours and suicidal tendencies. Two separate variables were also self-reported by the participants - the age of questioning of sexual orientation and the age of acceptance of sexual orientation. We subsequently recoded a new variable, delayed acceptance of sexual orientation, by taking the difference between these two variables, regressing it as an independent and dependent variable to deduce its psychosocial correlates, as well as its association with other measured instruments of health.ResultsAs a dependent variable, delayed acceptance of sexual orientation is positively associated with an increase of age and internalised homophobia, while being negatively associated with reporting as being gay, compared to being bisexual or queer. As an independent variable, delayed acceptance of sexual orientation was associated with a delayed age of coming out to siblings and parents, suicide ideation, historical use of substances including smoking tobacco cigarettes and consuming marijuana, as well as reporting higher levels of experienced, internalised and perceived homophobia.ConclusionGreater levels of early intervention and efforts are required to reduce the heightened experience of minority stress resulting from communal and institutional hostilities. Areas of improvement may include community-based counselling and psychological support for GBQ men, while not forsaking greater education of the social and healthcare sectors. Most importantly, disrupting the stigma narrative of a GBQ 'lifestyle' is paramount in establishing an accepting social environment that reduces the health disparity faced by GBQ men.

Project description:ObjectiveThe purpose of this study was to assess knowledge of human papillomavirus (HPV) as a cause of anal cancer among at-risk gay, bisexual, and other men who have sex with men (GBM).Materials and methodsSecondary analysis was conducted of cross-sectional data from 3 cycles of the Health Information National Trends Survey (2017, 2018, 2019). Results were reported for the subset of adults who identified as GBM (N = 212). Knowledge that HPV can cause anal cancer was the main outcome. Differences in knowledge were evaluated (using χ2 and multiple logistic regression) by demographic, health information factors, and access to care.ResultsSixty-eight percent of GBM were aware of HPV. Knowledge that HPV causes anal cancer was low (<20%) in the overall sample and sample of GBM (17.9%; 95% CI = 11.0-24.7). Gay, bisexual, and other men who have sex with men were no more knowledgeable that HPV causes anal cancer than heterosexual men (14.8%; 95% CI = 12.9-16.9; p = .376). College-educated GBM had higher odds (adjusted odds ratio = 3.50; 95% CI = 1.02-11.97) of knowing HPV causes anal cancer than GBM with no college degree. No other factors were associated with knowledge.ConclusionsGay, bisexual, and other men who have sex with men are largely unaware that HPV can cause anal cancer, despite high awareness of HPV itself. This is concerning given that GBM are at increased risk of HPV-associated anal cancer than the general population. Our findings suggest that information about anal cancer and health information about the benefits of HPV vaccination for anal cancer prevention are only reaching a small subset of college-educated GBM. Targeted anal cancer education programs are needed.

Project description:BackgroundThe purpose of this study was to evaluate the relationship between cognitive performance, risk factors for cardiovascular and cerebrovascular disease (CVD), and HIV infection in the era of highly active antiretroviral therapy.MethodsWe evaluated the cognitive functions of men enrolled in the cardiovascular disease substudy of the Multicenter AIDS Cohort Study who were aged > or =40 years, with no self-reported history of heart disease or cerebrovascular disease. Results from comprehensive neuropsychological evaluations were used to construct composite scores of psychomotor speed and memory performance. Subclinical CVD was assessed by measuring coronary artery calcium and carotid artery intima-media thickness (IMT), as well as laboratory measures, including total cholesterol, fasting glucose, glycosylated hemoglobin, glomerular filtration rate (estimated), and standardized blood pressure and heart rate measures.ResultsAfter accounting for education, depression, and race, carotid IMT and glomerular filtration rate were significantly associated with psychomotor speed, whereas IMT was associated with memory test performance. HIV serostatus was not significantly associated with poorer cognitive test performance. However, among the HIV-infected individuals, the presence of detectable HIV RNA in plasma was linked to lower memory performance.ConclusionsThese findings suggest that HIV infection may not be the most important predictor of cognitive performance among older gay and bisexual men in the post-highly active antiretroviral therapy era, at least among those with access to medical care and to appropriate medications. Medical factors associated with normal aging are significantly associated with performance on neuropsychological tests, and good clinical management of these factors both in HIV-infected individuals and those at risk for infection may have beneficial effects in the short term and could reduce the risk of subsequent cognitive decline.

Project description:BackgroundGay and bisexual men are disproportionately affected by HIV and other sexually transmissible infections (STIs), yet opportunities for sexual health testing of this population are often missed or incomplete in general practice settings. Strategies are needed for improving the uptake and completeness of sexual health testing in this setting.ObjectivesThe goal of the research was to evaluate the impact of an intervention centered around integrated decision support software and routine data feedback on the collection of sexual orientation data and sexual health testing among gay and bisexual men attending general practice.MethodsA study using before/after and intervention/comparison methods was undertaken to assess the intervention's impact in 7 purposively sampled Australian general practice clinics located near the urban centers of Sydney and Melbourne. The software was introduced at staggered points between April and August 2012; it used patient records to prompt clinicians to record sexual orientation and accessed pathology testing history to generate prompts when sexual health testing was overdue or incomplete. The software also had a function for querying patient management system databases in order to generate de-identified data extracts, which were used to report regularly to participating clinicians. We calculated summary rate ratios (SRRs) based on quarterly trends and used Poisson regression analyses to assess differences between the 12-month preintervention and 24-month intervention periods as well as between the intervention sites and 4 similar comparison sites that did not receive the intervention.ResultsAmong 32,276 male patients attending intervention clinics, sexual orientation recording increased 19% (from 3213/6909 [46.50%] to 5136/9110 [56.38%]) during the intervention period (SRR 1.10, 95% CI 1.04-1.11, P<.001) while comprehensive sexual health testing increased by 89% (305/1159 [26.32%] to 690/1413 [48.83%]; SRR 1.38, 95% CI 1.28-1.46, P<.001). Comprehensive testing increased slightly among the 7290 gay and bisexual men attending comparison sites, but the increase was comparatively greater in clinics that received the intervention (SRR 1.12, 95% CI 1.10-1.14, P<.001). In clinics that received the intervention, there was also an increase in detection of chlamydia and gonorrhea that was not observed in the comparison sites.ConclusionsIntegrated decision support software and data feedback were associated with modest increases in sexual orientation recording, comprehensive testing among gay and bisexual men, and the detection of STIs. Tests for and detection of chlamydia and gonorrhea were the most dramatically impacted. Decision support software can be used to enhance the delivery of sexual health care in general practice.
