RESUMEN

OBJECTIVE: This study investigates Japanese gay and bisexual men's experiences of seeking help for emotional support from others regarding their sexual orientation concerns. It examines the relationship between their help-seeking and presence of gay and bisexual peers, duration between questioning their sexual orientation and accepting it, and experience of coming out to family members by multiple logistic regression analysis. RESULTS: We conducted a cross-sectional survey using a self-reported paper questionnaire. There were 360 valid responses. Eighty-two respondents (22.8%) had experience of help-seeking for emotional support, and this was associated with age, occupation, presence of gay/bisexual friends, and experience of coming out to family members about their sexual orientation. Respondents sought the most help from their male friends (70.0%), followed by female friends (25.0%), mothers (17.5%), and the Internet (16.3%). Even after controlling for age and occupation, experience of help-seeking for emotional support was higher among participants who had gay/bisexual friends when they were aware of their sexual orientation, took < 1 year from questioning to realizing their sexual orientation, and had come out to their family about their sexual orientation.

RESUMEN

Suicide in young people is a challenge, but suicide rates in lesbian, gay, bisexual, transgender, queer or questioning (LGBTQ) youth are alarming. The current article explores the influence of several social determinates of health, specifically mental health care access and quality and education, on suicide among LGBTQ youth. Providers must recognize the mental health challenges and disparities in LGBTQ youth and address them to improve mental health and decrease suicide rates.

RESUMEN

The bond with healthcare services is a crucial dimension in facilitating the maternal journey of lesbian and bisexual women couples. This study aimed to analyze the culturally constructed meanings regarding the bond with healthcare services and professionals by lesbian and bisexual women who experienced dual motherhood. It is a qualitative investigation grounded in interpretative anthropology. The research corpus was built based on in-depth interviews with 10 lesbian and bisexual women, aged 30 to 39 years. The results indicate that access to parenthood, until its realization, involved a journey permeated by satisfactions and sufferings triggered by failed attempts and gestational losses. Challenges experienced in healthcare provision were also reported due to prejudices, lack of empathy, and unpreparedness of professionals in dealing with prenatal care for lesbian and bisexual women couples. Manifestations of discrimination were more pronounced concerning non-gestational mothers. The findings offer insights into implementing policies that prioritize humanization and planning programs and healthcare services based on culturally sensitive care for lesbian and bisexual women couples as they transition into dual motherhood.


O vínculo com os serviços de saúde é uma dimensão crucial para viabilizar o projeto materno de casais de mulheres lésbicas e bissexuais. Este estudo teve como objetivo analisar os significados culturalmente construídos sobre o vínculo com os serviços e profissionais de saúde por mulheres lésbicas e bissexuais que vivenciaram a dupla maternidade. Investigação qualitativa fundamentada na antropologia interpretativa. O corpus de pesquisa foi construído com base em entrevista em profundidade com 10 mulheres de 30 a 39 anos. Os resultados mostram que o acesso à parentalidade implicou um itinerário permeado por satisfações e sofrimentos devido a tentativas frustradas e perdas gestacionais. Também foram relatados percalços vivenciados na produção do cuidado em saúde devido a preconceitos, falta de empatia e despreparo de profissionais para lidarem com acompanhamento de pré-natal aos casais de mulheres lésbicas/bissexuais. As manifestações de discriminação foram mais contundentes em relação às mães não gestantes. Os resultados oferecem subsídios para implementação de políticas de humanização e planejamento de programas e serviços de saúde baseados em cuidados culturalmente sensíveis à diversidade para casais de mulheres lésbicas/bissexuais que vivenciam a transição para a maternidade.

RESUMEN

During the 2022 multicountry mpox outbreak, the United Kingdom identified cases beginning in May. UK cases increased in June, peaked in July, then rapidly declined after September 2022. Public health responses included community-supported messaging and targeted mpox vaccination among eligible gay, bisexual, and other men who have sex with men (GBMSM). Using data from an online survey of GBMSM during November-December 2022, we examined self-reported mpox diagnoses, behavioral risk modification, and mpox vaccination offer and uptake. Among 1,333 participants, only 35 (2.6%) ever tested mpox-positive, but 707 (53%) reported behavior modification to avoid mpox. Among vaccine-eligible GBMSM, uptake was 69% (95% CI 65%-72%; 601/875) and was 92% (95% CI 89%-94%; 601/655) among those offered vaccine. GBMSM self-identifying as bisexual, reporting lower educational qualifications, or identifying as unemployed were less likely to be vaccinated. Equitable offer and provision of mpox vaccine are needed to minimize the risk for future outbreaks and mpox-related health inequalities.

RESUMEN

BACKGROUND: This study is the first to analyze LGBT portrayals in a news media dataset over a decade (2010-2020). We selected Singapore as a country of interest, emblematic of a nation grappling with state-encouraged heteronormativity and a remnant colonial law against homosexuality (377A), fraught with calls for its repeal that was only enacted in 2022. Our study is interested in this period bookended by challenge and change, particularly in newspaper portrayals of LGBT narratives. Newspapers are an important source of current information and have the power to shape societal perceptions. We lay the groundwork and provide a framework to analyze news media narratives of other Commonwealth nations with colonial pasts and inherited laws criminalizing LGBT communities. OBJECTIVES: This study analyzes LGBT portrayals in a 400-million-word news media dataset over a decade (2010-2020). First, we aimed to track the volume of LGBT media coverage over time and elucidate differences in coverage of different identity markers. Second, we aimed to track sentiments on LGBT portrayals. Third, we aimed to track salient narratives circulated about LGBT stories. METHODS: The study leveraged a 400-million-word corpus from news media in Singapore, identifying the following target keywords: LGBT, Lesbian, Gay, Bisexual, Transgender, Pink Dot (a local Pride event), 377A. First, coverage volume was tracked using annual changes in keyword mentions per million, elucidating differences in coverage of different sub-groups. Second, sentiment analysis on a valence scale was conducted on LGBT collocates. Third, we distilled salient narratives about LGBT identities using thematic labelling of top-frequency collocates. RESULTS: First, overall coverage of LGBT steadily increased over the decade, though Gay identities evidenced asymmetrical coverage-outstripping 'Bisexual' keywords by seven times, 'Lesbian' by four, 'Transgender' by two. Second, sentiment scores for Pink Dot (a local pride event) were most positive; Lesbian, Gay, LGBT, Transgender were neutral; Bisexual and 377A dipped slightly negative. Third, topics differed across the four identities: uniquely, 'Lesbian' collocates related to sensationalized cinema; 'Gay' about hate crimes; 'Bisexual' about population surveys; 'Transgender' about challenges (transitioning, alienation, suicide). CONCLUSIONS: Practically, we presented a decade-long barometer of LGBT sentiments and themes on a national level, providing a framework to analyze media for more effective communication strategies-applicable to Commonwealth countries with similar inherited colonial laws. Salient repetition through media association may unwittingly frame certain issues negatively; caution is prudent in representing each sub-group adequately, rather than portraying the LGBT identity as monolithic.

RESUMEN

Background: Bisexual women, compared to heterosexual women, report greater amounts of alcohol use and heavy drinking. Alcohol expectancies (i.e., beliefs about alcohol outcomes) are a strong predictor of alcohol use, but few studies have examined the importance of alcohol expectancies in relation to alcohol use among bisexual women specifically or in comparison to heterosexual women. Objectives: The current study examined 262 heterosexual and 225 bisexual women using an online survey about alcohol use, sexual risk-taking, and alcohol expectancy subtypes (sexuality, tension reduction, and aggression). Results: Compared to heterosexual women, bisexual women reported greater sexuality and tension reduction expectancies after accounting for their level of drinking, but groups did not differ on aggression expectancies. Moreover, sexual identity status moderated the associations between sexuality and tension reduction expectancies and alcohol use, respectively. Specifically, our study findings suggested that sexuality and tension reduction alcohol expectancies were more strongly tied to alcohol use among bisexual women than heterosexual women. Conclusions: Taken together, in our study, bisexual women held stronger sexuality and tension reduction expectancies, as compared to heterosexual women. Interventions targeting alcohol expectancies may be considered when tailoring intervention content for this population.

RESUMEN

Older gay and bisexual men constitute diverse, sizable, and potentially vulnerable populations. They have and continue to face discrimination and stigma in multiple settings, including health care. Older gay and bisexual men report worse health, higher rates of alcohol and tobacco use, and higher HIV rates compared with their heterosexual counterparts. They have unique needs and experiences in multiple realms of health care including mental health, sexual health, and cancer screenings. Geriatric medicine physicians and providers can educate themselves on these unique needs and risks and take steps to provide inclusive, affirming care.

RESUMEN

Digital, self-guided mental health programs are a promising avenue for mental health support for LGBTQIA+ (lesbian, gay, bisexual, trans, Queer, intersex, asexual plus additional sexuality, gender, and romantic identities) people - however, healthcare providers (HCPs) perspectives on programs are largely unknown. The aim of this study was to explore these perspectives. A cross-sectional online survey was distributed across Australia, with a final sample of 540 HCPs from a range of disciplines. Most respondents (419, 81.2 %), reported that digital, self-guided mental health programs would be useful, but 74.5 % (n = 380) also reported that they had concerns. Thematic analysis of open-text responses showed that HCPs believe programs may help overcome access barriers and could be useful as part of a wider care journey. Others were concerned about patient safety, and whether programs could be appropriately tailored to LGBTQIA+ experiences. Content analysis of open-text responses showed affirming language and imagery, content on LGBTQIA+ people's unique challenges, wider health information, and connections to community were important to include in programs. HCPs advocated for programs that offered broad and sub-population specific information. These findings show that HCPs are enthusiastic about digital, self-guided mental health programs, but care should be taken to address key concerns to facilitate future implementation.

RESUMEN

Partner preferences are an important differential in relationship formation and evolutionary fitness, and vary according to individual, ecological, and social factors. In this study, we evaluated the variation in preference for intelligence, kindness, physical attractiveness, health, and socioeconomic level among individuals of different sexes and sexual orientations in a Brazilian sample. We analyzed the preference scores of 778 heterosexual, bisexual, and homosexual men and women in three budgeted mate design tasks (low vs. medium vs. high budget) and their association with sociosexuality, attachment styles, homogamy, and willingness to engage in short- and long-term relationships. Results indicated a global trait preference order, with intelligence ranking first, followed by kindness, physical attractiveness, health, and lastly by socioeconomic status. Typical sex differences were observed mostly within the heterosexual group, and specific combinations of sex and sexual orientation were linked to variation in preference for physical attractiveness, kindness, and socioeconomic status. We also found unique associations of the other variables with partner preferences and with willingness to engage in short- or long-term relationships. By exploring the partner preferences of non-heterosexual individuals from a Latin American country, an underrepresented group in evolutionary psychology research, our results help understand the universal and specific factors that guide partner preferences and human sexual behavior.

RESUMEN

Lesbian, gay, bisexual, transgender, queer, or similarly identified (LGBTQ+) people experience substantial mental health disparities compared to heterosexuals. The "Let's Connect" intervention was designed to improve mental health outcomes for LGBTQ+ people. This impact evaluation aimed to assess effectiveness of this intervention during its pilot phase, using a single arm pilot trial. Respondents completed baseline surveys at intervention start, a post survey on the last day of the intervention (at 6 weeks), then a follow-up survey 6 weeks after the intervention ended (at 12 weeks). Pre-post differences in outcomes were analyzed using paired t-tests, chi-square tests, and generalized estimating equations to evaluate impact on mental health outcomes at 6 and 12 weeks, and identify characteristics associated with loss to follow-up. The average value of all three outcome measures decreased substantially between the baseline and post surveys; all of these differences were highly statistically significant, and further decreased between the end of the intervention at 6 weeks and the 12 week follow-up survey. Let's Connect participants did experience substantial improvements in mental health outcomes, on average, between the start and end of this intervention. Further study of this intervention using a randomized design and control group is warranted.

RESUMEN

OBJECTIVE: Structural forms of stigma and discrimination are associated with adverse health outcomes across numerous stigmatized groups, including lesbian, gay, and bisexual (LGB) individuals. However, the biological consequences of structural stigma among LGB populations are understudied. To begin to address this gap, we assessed associations between indicators of structural stigma (i.e., state-level policies) targeting LGB individuals and allostatic load (AL) indices representing physiological dysregulations. METHODS: Pooled data from the continuous 2001-2014 National Health and Nutritional Examination Survey were analyzed (LGB: n = 864; heterosexual: n = 20,310). Ten state-level LGB-related policies (e.g., employment nondiscrimination protections, same-sex marriage) were used to operationalize structural stigma. A sex-specific AL index representing 11 immune, metabolic, and cardiovascular biomarkers was estimated. Multilevel models were used to examine associations between structural stigma and AL, net of nine individual-level characteristics (e.g., education, race/ethnicity, age, and health behaviors). RESULTS: Sexual minority men living in states with low levels of structural stigma experienced significantly lower AL ( ß = -0.45, p = .02) compared with sexual minority men living in states with high structural stigma (i.e., fewer protective policies). There was no significant association between structural stigma and AL among sexual minority women. CONCLUSIONS: By demonstrating direct associations between structural stigma and indices of physiological dysregulation, our findings provide a mechanistic understanding of how the social environment can "get under the skin and skull" for sexual minority men in the United States. Future research should explore whether these mechanisms generalize to other marginalized groups exposed to structural stigma.

RESUMEN

We introduce internalized heterosexist racism (IHR), or the internalization of damaging stereotypes, harmful beliefs, and negative attitudes about being a sexual minority person of color. We also present the initial development and validation of the Brief Internalized Heterosexist Racism Scale for gay and bisexual Black men (IHR-GBBM), a unidimensional, 10-item measure of IHR. Exploratory factor analyses on an internet-obtained sample of gay and bisexual Black men (N = 312; Mean age = 30.36 years) show that the IHR-GBBM had evidence of good internal consistency, and good convergent, discriminant, concurrent, and incremental validity. The IHR-GBBM was positively correlated with internalized racism, internalized heterosexism, and discrimination (racist, heterosexist). IHR was also negatively correlated with race stigma consciousness, weakly positively correlated with sexual identity stigma consciousness, but not correlated with either race identity, sexual identity, or social desirability. Hierarchical regressions showed that the IHR-GBBM explained an additional variance of 2.8% and 3.1% in anxiety symptoms and substance use coping, respectively, after accounting for (1) sociodemographics, (2) internalized racism and internalized heterosexism, and (3) an interaction of internalized racism and internalized heterosexism. Older participants and those who were "out" about their sexual identity reported lower IHR. Those who did not know/want to report their HIV status reported greater IHR. Results revealed no sexual identity, sexual position, relationship status, income, education, or employment status differences in IHR. We hope the development of the IHR-GBBM spurs future research on predictors and consequences of IHR. We discuss limitations and implications for the future study of internalized heterosexist racism.

RESUMEN

Monkeypox virus belongs to the genus Orthopoxvirus There was a worldwide mpox outbreak in 2022, with many cases reported in Europe in gay, bisexual and other men who have sex with men. Here, we report a case of mpox diagnosed in a heterosexual woman in her twenties without any known history of exposure. This is a very rare event. Despite lesions remaining for more than 1 month, she recovered fully with no sequelae. We highlight the diagnosis of mpox in a heterosexual woman without a known or suspected history of exposure or any risk factor for acquiring the infection.

RESUMEN

Sexual problems are common among gay, bisexual, and other men who have sex with men (GBM) after diagnosis with HIV. However, these are often overlooked in care and research, where sexual risk reduction and biomedical aspects of sexual health tend to dominate. We conducted a rapid scoping review to investigate which sexual problems of GBM living with HIV are addressed by interventions, and the barriers and facilitators to their implementation. Literature from high-income countries published in English since 2010 was reviewed. Medline, Embase, PsycInfo, and Scopus databases were searched on July 4, 2022. Targeted sexual problems were categorized according to the ten dimensions of Robinson's Sexual Health Model, and barriers and facilitators, according to the five domains of the Consolidated Framework for Implementation Research (CFIR). Interventions focused solely on the dimension of Sexual Health Care/Safer Sex were excluded. Relevant information was extracted from the qualifying documents with NVivo 12 software for content analysis. Fifty-two documents were included, referring to 37 interventions which mainly took place in the United States (n = 29/37; 78%), were group-based (n = 16; 41%), and used counselling techniques (n = 23; 62%; e.g., motivational interviewing, cognitive-behavioral therapy). Their settings were mostly primary care (n = 15; 40%) or community-based (n = 16; 43%). On average, interventions addressed three sexual health dimensions (SD = 2; range: 1-10). The most targeted dimension was Sexual Health Care/Safer Sex (n = 26; 70%), which concerned sexual risk reduction. Next, Challenges (n = 23; 62%), included substance use (n = 7; 19%), sexual compulsivity (n = 6; 16%), sexual abuse (n = 6; 16%), and intimate partner violence (n = 4; 11%). Third was Talking About Sex (n = 22; 59%) which mostly concerned HIV disclosure. About a third of interventions addressed Culture/Sexual identity (n = 14; 38%), Intimacy/Relationships (n = 12; 33%), and Positive sexuality (n = 11; 30%). Finally, few targeted Body Image (n = 4; 11%), Spirituality (n = 3; 8%), Sexual Anatomy Functioning (n = 2; 5%) or Masturbation/Fantasy (n = 1; 3%). Forty-one documents (79%) mentioned implementation barriers or facilitators, particularly about the characteristics of the interventions (41% and 78%, respectively; e.g., cost, excessive duration, acceptability, feasibility) and of the individuals involved (37% and 46%; e.g., perceived stigmatization, provider expertise). The other three CFIR dimensions were less common (5%-17%). The search strategy of this review may not have captured all eligible documents, due to its limit to English-language publications. Overall, most interventions incorporated a focus on Sexual Health Care/Safer Sex, at the expenses of other prevalent sexual problems among GBM living with HIV, such as intimate partner violence (Challenges), erectile dysfunction (Sexual Anatomy Functioning), and Body Image dissatisfaction. These findings suggest they could receive more attention within clinical care and at the community level. They also highlight the importance of cost-effective and acceptable interventions conducted in non-stigmatizing environments, where patients' needs can be met by providers who are adequately trained on sexuality-related topics.

RESUMEN

The naturally occurring bisexual cone of gymnosperms has long been considered a possible intermediate stage in the origin of flowers, but the mechanisms governing bisexual cone formation remain largely elusive. Here, we employed transcriptomic and DNA methylomic analyses, together with hormone measurement, to investigate the molecular mechanisms underlying bisexual cone development in the conifer Picea crassifolia. Our study reveals a "bisexual" expression profile in bisexual cones, especially in expression patterns of B-class, C-class and LEAFY genes, supporting the out of male model. GGM7 could be essential for initiating bisexual cones. DNA methylation reconfiguration in bisexual cones affects the expression of key genes in cone development, including PcDAL12, PcDAL10, PcNEEDLY, and PcHDG5. Auxin likely plays an important role in the development of female structures of bisexual cones. This study unveils the potential mechanisms responsible for bisexual cone formation in conifers and may shed light on the evolution of bisexuality.

RESUMEN

OBJECTIVES: To apply an intersectional lens to disparities in emotional distress among youth, including multiple social positions and experiences with bias-based bullying. METHODS: Data are from the 2019 Minnesota Student Survey (n = 80 456). Social positions (race and ethnicity, sexual orientation, gender) and 2 forms of bias-based bullying (racist, homophobic or transphobic) were entered into decision tree models for depression, anxiety, self-injury, suicidal ideation, and suicide attempts. Groups with the highest prevalence are described. Rates of emotional distress among youth with matching social positions but no bias-based bullying are described for comparison. RESULTS: LGBQ identities (90%) and transgender, gender diverse, and questioning identities (54%) were common among the highest-prevalence groups for emotional distress, often concurrently; racial and ethnic identities rarely emerged. Bias-based bullying characterized 82% of the highest-prevalence groups. In comparable groups without bias-based bullying, emotional distress rates were 20% to 60% lower (average 38.8%). CONCLUSIONS: Findings highlight bias-based bullying as an important point for the intervention and mitigation of mental health disparities, particularly among lesbian, gay, bisexual, transgender, gender-diverse, queer, and questioning adolescents. Results point to the importance of addressing bias-based bullying in schools and supporting lesbian, gay, bisexual, transgender, gender-diverse, queer, and questioning students at the systemic level as a way of preventing emotional distress.

RESUMEN

BACKGROUND: Minority stress from racism and heterosexism may uniquely interact to impact the mental health of racialized sexual minorities. We examined variations in anxiety and depressive symptoms by reported by ethno-racial identity among gay, bisexual, and other men who have sex with men (gbMSM) in Vancouver, Canada. METHODS: We recruited gbMSM aged ≥ 16 years from February 2012 to February 2015 using respondent-driven sampling (RDS). Participants completed computer assisted self-interviews (CASI) at enrollment and every 6 months until February 2017. We examined factors associated with moderate/severe anxiety and depression scores (> 10) on the Hospital Anxiety and Depression Scale (HADS) and differences in key explanatory variables including sociodemographic, psychosocial, and substance use factors. We used multivariable mixed effects models to assess whether moderate/severe scores were associated with ethno-racial identity across all visits. RESULTS: After RDS-adjustment, of 774 participants, 79.9% of participants identified as gay. 68.6% identified as white, 9.2% as Asian, 9.8% as Indigenous, 7.3% as Latin American, and 5.1% as other ethno-racial identities. Participants contributed a median of 6 follow-up visits (Q1-Q3: 4-7). In the multivariable analysis, Asian participants had decreased odds of moderate/severe anxiety scores compared to white participants (aOR = 0.39; 95% CI: 0.18-0.86), and Latin American participants had decreased odds of moderate/severe depression scores compared to both white (aOR = 0.17; 95% CI: 0.08-0.36) and Asian (aOR = 0.07; 95% CI: 0.02-0.20) participants. CONCLUSION: Asian and Latino gbMSM reported decreased mental health symptoms compared to white participants. Asian and Latino gbMSM in Vancouver appear to manage multiple minority stressors without adversely affecting their mental health.

RESUMEN

Because human same-sex sexual behavior (SSB) is heritable and leads to fewer offspring, how SSB-associated alleles have persisted and whether they will remain in human populations are of interest. Using the UK Biobank, we address these questions separately for bisexual behavior (BSB) and exclusive SSB (eSSB) after confirming their genetic distinction. We discover that male BSB is genetically positively correlated with the number of offspring. This unexpected phenomenon is attributable to the horizontal pleiotropy of male risk-taking behavior-associated alleles because male risk-taking behavior is genetically positively correlated with both BSB and the number of offspring and because genetically controlling male risk-taking behavior abolishes the genetic correlation between male BSB and the number of offspring. By contrast, eSSB is genetically negatively correlated with the number of offspring. Our results suggest that male BSB-associated alleles are likely reproductively advantageous, which may explain their past persistence and predict their future maintenance, and that eSSB-associated alleles are likely being selected against at present.

RESUMEN

INTRODUCTION: Prevalence and patterns of alcohol and other drug (AOD) use among specific lesbian, gay, bisexual, transgender (trans) and queer (LGBTQ+) subpopulations are well established. However, patterns of substance-related risk have been less thoroughly explored. This study aimed to determine typologies AOD risk among LGBTQ+ adults in Australia. METHOD: Latent class analyses were performed to determine distinct patterns of AOD risk (n = 6835), as measured by the Alcohol Use Disorder Identification Test and Drug Abuse Screening Tool. Demographic characteristics, experience of harassment, assault and/or threats, mental wellbeing and LGBTQ+ connectedness were compared across emergent classes. RESULTS: AOD risk was characterised as 'no risk' (13.3% of sample), 'low risk' (15.1%), 'moderate risk' (alcohol + other drugs; 30.1%), or 'moderate alcohol only risk' (41.5%). The 'moderate risk' class was the most likely class to report recent sexual assault, verbal abuse, harassment and physical threats compared to other classes, while those in the 'moderate alcohol only risk' group were least likely to report these experiences of all classes. However, both the 'moderate risk' and 'moderate alcohol risk only' classes reported greater mental wellbeing and LGBTQ+ connectedness compared to the 'no risk' and 'low risk' classes. DISCUSSION AND CONCLUSIONS: Our findings indicate that level of AOD risk is not uniform among some LGBTQ+ adults, nor is the distribution of harms experienced by them. Tailored harm-reduction interventions may be fruitful in attenuating harms based on risk profile; most specifically, LGBTQ+ individuals engaging in moderately risky concurrent AOD use.
