Male, female, and mixed-sex poplar plantations support divergent soil microbial communities.

Males and females of dioecious plants have sex-specific adaptations to diverse habitats. The effects of inter- and intrasexual interactions in poplar plantations on composition, structure, and function of soil microbiota have not been explored in degraded areas. We conducted a series of greenhouse and field experiments to investigate how belowground competition, soil microbial communities, and seasonal variation nitrogen content differ among female, male, and mixed-sex Populus cathayana plantations. In the greenhouse experiment, female neighbors suppressed the growth of males under optimal nitrogen conditions. However, male neighbors enhanced stable isotope ratio of nitrogen (δ15 N) of females under intersexual competition. In the field, the root length density, root area density, and biomass of fine roots were lower in female plantations than in male or mixed-sex plantations. Bacterial networks of female, male, and mixed-sex plantations were characterized by different composition of hub nodes, including connectors, modules, and network hubs. The sex composition of plantations altered bacterial and fungal community structures according to Bray-Curtis distances, with 44% and 65% of variance explained by the root biomass, respectively. The total soil nitrogen content of mixed-sex plantation was higher than that in female plantation in spring and summer. The mixed-sex plantation also had a higher ß-1,4-N-acetyl-glucosaminidase activity in summer and a higher nitrification rate in autumn than the other two plantations. The seasonal soil N content, nitrification rate, and root distribution traits demonstrated spatiotemporal niche separation in the mixed-sex plantation. We argue that a strong female-female competition and limited nitrogen content could strongly impede plant growth and reduce the resistance of monosex plantations to climate change and the mixed-sex plantations constitutes a promising way to restore degraded land.

Sexual Identity Development and Social Ecological Facilitators and Barriers of PrEP Uptake and Adherence Among Latinx Men Who Have Sex with Men.

Latinx gay, bisexual, and other men who have sex with men (LMSM) report lower pre-exposure prophylaxis (PrEP) use than their white, non-Latinx counterparts. We hypothesize that this disparity is partially attributable to social ecological factors that can be addressed via prevention interventions. In this retrospective study, we first examined data from 253 LMSM to determine whether theorized associations existed between acquisition of a PrEP prescription (uptake) in relation to several social ecological factors based on a conceptual framework of determinants of access to and uptake of PrEP for LMSM. We also explored relations between frequency of PrEP use (adherence) and social ecological factors with a subsample of 33 LMSM who had initiated PrEP 12 months prior to assessment. In this study, individual-level factors from this framework included age and socioeconomic status. Perceived access to medical care represented both individual- and community-level determinants of PrEP uptake and adherence. Interpersonal-level factors were social support and relationship status. Structural/cultural-level factors were sexual identity development status, the masculinity norm of heterosexual self-presentation, traditional Latinx masculine gender role beliefs of machismo and caballerismo, racial identity, and immigration status. Results indicated that older men and those who endorsed the synthesis/integration status of sexual identity development were more likely to acquire a PrEP prescription during their lifetime in comparison to peers. PrEP adherence was linked with being older, reporting higher socioeconomic status, reporting more appraisal social support, self-identifying as white-Latinx, being U.S.-born, and endorsing less sexual identity uncertainty and more heterosexual self-presentation. Results specify modifiable factors that may inform tailored, community-based prevention efforts to increase PrEP use and decrease existing HIV/AIDS disparities among LMSM.

Differences in Minority Stress Experiences, Mental Health, and Relationship Quality Outcomes Among Bisexual, Pansexual, and Queer Women.

The majority of sexual minority women in the United States today identify as bi+. Recent research suggests that "non-traditional" bi+ labels such as pansexual and queer are being adopted more frequently than ever before, making it increasingly important to evaluate whether these women have unique needs. In the current study, we explored differences in minority stress experiences, mental health, and relationship quality outcomes by sexual identity label among women who identify with the most common bi+ labels: bisexual, pansexual, and queer. Participants were 285 bi+ cisgender women in romantic relationships. They completed online measures of minority stress (antibisexual experiences, identity concealment, disconnection from the sexual and gender minority (SGM) community, and internalized stigma), mental health (depression and anxiety), and relationship quality (satisfaction and commitment). Overall, participants reported similar experiences of minority stress and few differences in their mental health outcomes. However, there were differences in antibisexual experiences by sexual identity label, such that pansexual women reported more frequent antibisexual experiences than bisexual and queer women. There were also differences in relationship quality by sexual identity label, such that bisexual women reported higher satisfaction than pansexual women and higher commitment than both pansexual and queer women. Findings suggest that pansexual and queer women may be facing their own unique challenges, even compared to bisexual women. Clinical prevention and intervention efforts can be tailored for these women to include strategies to cope with more frequent exposure to antibisexual experiences, as well as relationship education and skill-building to promote healthy romantic relationships.

Who Cares? Unpaid Caregiving by Sexual Identity, Gender, and Partnership Status Among U.S. Adults.

Recent scholarship indicates that sexual minority adults have higher caregiving rates than heterosexuals and that women are more likely to be caregivers than men. However, little research has addressed how gender and sexuality intersect in shaping caregiving status. This study uses data from the Behavioral Risk Factor Surveillance System and aggregates a probability-based sample of adults living in 36 U.S. states between 2015 and 2021. We examine who provides care among adult heterosexual, lesbian, gay, and bisexual men and women. Results reveal that women are more likely to be caregivers than men, but only among heterosexuals. We find little variation in caregiving by sexuality among women, but bisexual men are more likely than heterosexual men to be caregivers; the latter result appears to be driven by unpartnered, bisexual men. Lastly, we contextualize caregivers' experiences and reveal selected descriptive differences in patterns of care recipient-caregiver relationships across gender and sexual identity groups. Our findings advance understanding of caregiving and changing family ties in an era of population aging and increasing diversity in sexual identities.

Responses to Sexual and Gender Identity Measures in Population-Level Data by Birth Cohort: A Research Note.

The measurement of sexual and gender identity in the United States has been evolving to generate more precise demographic estimates of the population and a better understanding of health and well-being. Younger cohorts of sexual- and gender-diverse adults are endorsing identities outside of the lesbian, gay, bisexual, and transgender (LGBT) labels. Current population-level surveys often include a category such as "something else" without providing further details, and doing so inadequately captures these diverse identities. In this research note, our analysis of the most recent federal data source to incorporate sexual and gender identity measures-the Household Pulse Survey-reveals that younger birth cohorts are more likely to select "something else" for their sexual identity and "none of these" for their gender identity. The observed sexual and gender identity response patterns across birth cohorts underscore the importance of developing and applying new strategies to directly measure sexual- and gender-diverse adults who identify with identities outside of those explicitly captured on surveys. The integration of sexual and gender identity measures in population-level surveys carries broader implications for civil rights and for addressing health inequities and therefore must be responsive to cohort differences in identification.

Prevalence of sexual harassment and its association with aspects self-reported health: A cross-sectional study in Sweden.

AIMS: Sexual harassment is common and may have serious consequences for well-being and health. We investigated the prevalence of sexual harassment in the general population of Stockholm County across socio-demographic groups and sexual identity, and its association with self-reported health. METHODS: Experiences of sexual harassment in the previous 12 months and its associations with self-reported health (depression, anxiety, suicidal ideation) were assessed in 2021/2022 among a random sample of 22,890 residents in Stockholm County aged 16 and older. Analyses were done using descriptive statistics and multivariate logistic regression (odds ratios and 95% confidence intervals (CI)). Calibration weights were used to estimate population-representative rates with 95% CI. RESULTS: The highest weighted prevalence was observed among 16- to 24-year-olds (18.9%, 95% CI 16.9%-20.9%). Women (9.5%; 95% CI 8.8%-10.1%) reported a higher prevalence than men (2.9%; 95% CI 2.5%-3.3%). Compared to heterosexual people, bisexual and homosexual people reported a higher prevalence of sexual harassment. No significant difference was observed related to country of birth. People who were students, unemployed or on sick leave were more exposed than employed people, although this was not significant when adjusted for age and registered sex. Experiences of sexual harassment was associated with higher odds of all aspects of self-reported health. CONCLUSIONS: Experiences of sexual harassment in the general population are common and associated with adverse self-reported health. There is a need for enhanced efforts to prevent sexual harassment in the general population and to empower specific risk groups such as women and sexual minorities.

The juxtaposition of invalidation and "inviting in": a qualitative study of bisexual identity in South Africa.

Understanding one's sexual orientation plays a significant role in contributing to one's sexual identity and developing a coherent sense of self. Misconceptions and prevailing prejudices make it difficult for bisexual individuals to navigate their sexual identities in many societies. Disclosure of one's identity is accompanied by certain risks depending on how the information is received. However, disclosing one's identity can also be positive, especially as it assists in fostering relationships. This article derives from a descriptive study involving 14 semi-structured interviews with young adults aged 18-24 who identified as bisexual. Data were subjected to a reflexive thematic analysis. Themes of invalidation, belongingness and reclaiming through 'inviting in' were identified. By processing the feelings of invalidation regarding their bisexual identities which were placed upon them by their respective cultural groups, and society in general, participants were able to develop a sense of agency and reclaim their power. Findings highlight the need for further research on bisexuality, particularly in South Africa, and the need to understand how bisexual identity development occurs in interaction with other sexual and gender identities.

Stress of being outed to parents, LGBTQ family support, and depressive symptoms among sexual and gender diverse youth.

Limited scholarship has explored how a lack of agency in identity disclosure (being "outed") to parents is associated with mental health experiences of sexual and gender diverse youth (SGDY). With a national sample of SGDY (N = 9272; 66.8% White non-Hispanic) aged 13-17 (Mage = 15.63, SD = 1.24), this study first compared social position differences between SGDY who were outed to their parents compared to those not outed, and second, investigated how the stress from being outed to parents was associated with LGBTQ family support and depressive symptoms. Results revealed that SGDY who were outed to their parents reported higher levels of depressive symptoms and lower amounts of LGBTQ family support than SGDY who were not outed to their parents. In addition, greater stress from being outed to parents was indirectly associated with higher depressive symptoms through lower LGBTQ family support. These relationships significantly varied across gender identity. Findings highlight the importance of instilling greater agency in disclosure experiences among SGDY.

Subtypes of Alcohol Expectancies Are Differentially Associated With Alcohol Use for Bisexual and Heterosexual Women.

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.

Operational status of mental health, substance use, and problem gambling services: A system-level snapshot two years into the COVID-19 pandemic.

BACKGROUND: The aim of this paper is to provide a system-level snapshot of the operational status of mental health, substance use, and problem gambling services 2 years into the pandemic in Ontario, Canada, with a specific focus on services that target individuals experiencing vulnerable circumstances (e.g., homelessness and legal issues). METHODS: We examined data from 6038 publicly funded community services that provide mental health, substance use, and problem gambling services in Ontario. We used descriptive statistics to describe counts and percentages by service type and specialisation of service delivery. We generated cross-tabulations to analyse the relationship between the service status and service type for each target population group. RESULTS: As of March 2022, 38.4% (n = 2321) of services were fully operational, including 36.0% (n = 1492) of mental health, 44.1% (n = 1037) of substance use, and 23.4% (n = 78) of problem gambling services. These service disruptions were also apparent among services tailored to sexual/gender identity (women/girls, men/boys, 2SLGBTQQIA + individuals), individuals with legal issues, with acquired brain injury, and those experiencing homelessness. CONCLUSION: Accessible community-based mental health, substance use and problem gambling services are critical supports, particularly for communities that have historically contended with higher needs and greater barriers to care relative to the general population. We discuss the public health implications of the findings for the ongoing pandemic response and future emergency preparedness planning for community-based mental health, substance use and problem gambling services.

Positive masculinity programmes and attitudes towards nonconforming gender identities among young males in urban Democratic Republic of Congo, Nigeria, and Rwanda.

Implementing programmes on sexual and reproductive health and rights (SRHR) in sub-Saharan Africa often involves promoting inclusive sexual identity/orientation. However, whether and how the programmes are changing gender norms in the target populations have not been established. This study was designed to determine whether participation in Positive Masculinity (PM) programmes can change attitudes associated with prevailing gender norms. We explored attitudes towards nonconforming sexual identity/orientation among young males in selected informal settlements in Democratic Republic of the Congo (DRC), Nigeria and Rwanda. The key variables we tested included "country of participation" and other socio-demographics such as "education", "marital status" and "prior residential location" (rural or urban). We found no significant association between participation in PM programmes with attitudes towards nonconforming sexual identities/orientations across our target populations irrespective of educational qualification, marital status, and previous location of residence. By contrast, religious teachings showed up in the qualitative responses as a significant factor influencing young people's resistance to PM programmes' advocating for inclusive sexuality. Additionally, negative masculinity attributes had significant negative association with attitudes towards nonconforming sexual identity, while respondents with violent tendencies showed significant positive attitudes. We conclude that current PM interventions do not significantly contribute to positive attitudes towards inclusive sexuality in DRC, Nigeria, and Rwanda.

La mise en œuvre de programmes sur la santé et les droits sexuels et reproductifs (SDSR) en Afrique subsaharienne implique souvent la promotion d'une identité/orientation sexuelle inclusive. Cependant, il n'a pas été établi si et comment les programmes modifient les normes de genre dans les populations cibles. Cette étude a été conçue pour déterminer si la participation à des programmes de masculinité positive (PM) peut changer les attitudes associées aux normes de genre dominantes. Nous avons exploré les attitudes à l'égard de l'identité/orientation sexuelle non conforme chez les jeunes hommes dans des quartiers informels sélectionnés en République démocratique du Congo (RDC), au Nigeria et au Rwanda. Les variables clés que nous avons testées comprenaient le « pays de participation ¼ et d'autres données sociodémographiques telles que « l'éducation ¼, « l'état civil ¼ et « le lieu de résidence antérieur ¼ (rural ou urbain). Nous n'avons trouvé aucune association significative entre la participation à des programmes de PM et les attitudes à l'égard des identités/orientations sexuelles non conformes au sein de nos populations cibles, indépendamment du diplôme, de l'état civil et du lieu de résidence précédent. En revanche, les enseignements religieux sont apparus dans les réponses qualitatives comme un facteur important influençant la résistance des jeunes aux programmes PM prônant une sexualité inclusive. De plus, les attributs négatifs de la masculinité présentaient une association négative significative avec les attitudes à l'égard d'une identité sexuelle non conforme, tandis que les répondants ayant des tendances violentes montraient des attitudes positives significatives. Nous concluons que les interventions actuelles de PM ne contribuent pas de manière significative à des attitudes positives envers une sexualité inclusive en RDC, au Nigeria et au Rwanda.

Understanding Attraction, Behavior, and Identity in the Asexual Community.

Models of sexuality have evolved substantially in the past several decades through the inclusion of new aspects which were previously overlooked. Components such as romantic attraction and behavior have also traditionally been included in models of sexuality. However, romantic and sexual orientations do not coincide for all individuals. A population for which this is true and one that has developed a robust language for discussing romantic orientation is the asexual community. The current study aimed to explore romantic and sexual orientation through patterns found within the factors of attraction, behavior, and identity in the asexual community. The current sample composed of individuals who identified as asexual (N = 306, Mage = 27.1) was 61% female, 13% non-binary, and 10% self-described or used multiple labels. Within this sample, aspects of sexual and romantic orientations and experiences were measured, including fluidity, the quantity and type of self-identified labels, desire for romance or sex, and the role of contextual influences on these experiences. These aspects were used as the primary characteristics to construct participant profiles, both complete profiles and factor specific (attraction, behavior, identity). t-distributed stochastic neighbor embedding (tSNE) was used to find patterns of similarity between individual participant profiles. Overall, it appeared that attraction was the factor most closely associated with overall experiences; however, substantial variability existed between participants. These findings provide a mechanism for better understanding of some nuances of romantic and sexual orientation and may be a useful first step toward future inquiry and hypothesis generation.

Gender and sexual identity-based inequalities in adolescent wellbeing: findings from the #BeeWell Study.

BACKGROUND: Gender and sexual minority adolescents experience greater symptoms of psychological distress than their peers, but little is known about broader aspects of their wellbeing. This study examines wellbeing inequalities relating to gender and sexual identity among adolescents from Greater Manchester in the United Kingdom. METHOD: 37,978 adolescents (aged 12-15, attending 165 secondary schools) completed surveys of life satisfaction, positive and negative affect (hedonic framework); autonomy, self-esteem, optimism, and positive relationships (eudaimonic framework); and, symptoms of distress and mental wellbeing (complete state framework). Structural correlated factors models were used to assess gender and sexual identity wellbeing inequalities. RESULTS: The magnitude of wellbeing inequalities pertaining to gender and sexual identity were routinely substantially greater than those concerning other characteristics (e.g., socio-economic disadvantage). Gender identity wellbeing inequalities followed a consistent pattern, with the largest disparities evident between gender diverse adolescents and boys. Sexual identity wellbeing inequalities also followed a consistent pattern, with the largest disparities evident between sexual minority youth (both gay/lesbian and bi/pansexual) and their heterosexual peers. Finally, variation was evident across wellbeing domains. For example, observed gender identity (boys vs. girls) and sexual identity (heterosexual vs. sexual minority) disparities were substantially greater for symptoms of distress than for mental wellbeing in the complete state model. CONCLUSIONS: LGBTQ + adolescents experience lower wellbeing than their peers, and this is evident across a range of wellbeing domains. Accordingly, there is an urgent need for the prioritisation of improved prevention and intervention efforts that can better meet the needs of gender diverse and sexual minority youth, and future research should be conducted to improve understanding of the mechanisms underpinning the wellbeing inequalities observed.

Cantando En Las Sombras.

Cantando En La Sombras is a cathartic work that provides an unexpected repose to my consistently restless mind. A multi-sensory experience, this essay is a self-reflective piece that speaks to my sexual identity and journey of self-discovery through prose and song. Inspired by the groundbreaking work Chicana Lesbians: The Girls Our Mothers Warned Us About (Trujillo, 1994), I found the fortitude and autochthonous voice to tell my story, my way, through the candor, realism, and integrity in the stories of women who not only dared to live their truths but to immortalize them in words. The work is unceremonious and intimate, and although it is unique to me, when the audience reads my story and hears my songs, they may be reminded of the other contributors to the anthology-their hopes, dreams, struggles, and heartbreaks. My hope is that readers find their own veracity, substance, and strength reflected in my words and music, and realize that we are all hermanas, "…mujeres extranjeras, compartiendo la misma alma."

Society for Maternal-Fetal Medicine Special Statement: Commitment to excellence in obstetrical care, research, and education for people with diverse sexual and gender identities.

The Society for Maternal-Fetal Medicine seeks to ensure excellence in obstetrical outcomes for all people who desire or experience pregnancy, including people with diverse sexual and gender identities. The Society commits to the use of practices in clinical and research settings that affirm the sexual and gender identities of all people, encourages the development of undergraduate and graduate medical education curricula and training programs that address diverse pathways to pregnancy and support clinicians with diverse sexual and gender identities, and promotes the use of inclusive language that is accurate and, when possible, specific.

Race and Sexual Identity Differences in PrEP Continuum Outcomes Among Latino Men in a Large Chicago Area Healthcare Network.

U.S. HIV incidence is threefold higher among Latino individuals than non-Latino Whites. Pre-exposure prophylaxis (PrEP) uptake remains low among Latino men. Most HIV studies view Latino communities as a monolithic group, ignoring racial and sexual diversity. This analysis examines PrEP-related outcomes including eligibility, first prescription, and second prescription across race and sexual identity in a sample of Latino cisgender men (n = 8271) who sought services from a healthcare network in Chicago in 2012-2019. Logistic regression was used to calculate adjusted odds ratios. Latino-only participants had lower odds of PrEP eligibility and first prescription compared to White-Latino participants. No other significant differences by race were detected. While bisexual participants had equivalent odds of PrEP eligibility, they had lower odds of first PrEP prescription compared to gay participants. Heterosexual participants also had lower odds of PrEP eligibility and initiation. Future research should address unique factors shaping PrEP-related outcomes among diverse Latino populations.

RESUMEN: La incidencia del VIH en los EEUU és 3 veces mayor entre las personas latinos que entre los blancos no latinos. La iniciación de la profilaxis previa a la exposición (PrEP) sigue siendo baja entre los hombres latinos. La mayoría de los estudios sobre el VIH ven a las comunidades latinos como un grupo monolítico, ignorando la diversidad racial y sexual. Este análisis examina los resultados relacionados con la PrEP, incluida la elegibilidad, la primera prescripción y la segunda prescripción según la raza y la identidad sexual en una muestra de hombres latinos cisgénero (n = 8.271) que buscaron servicios de una gran red de servicios de salud en Chicago 2012­2019. Se utilizó la regresión logística para calcular las razones de momios ajustadas. Los participantes que solo eran latinos tenían menores probabilidades de ser elegibles para PrEP y de recibir la primera prescripción en comparación con los participantes de blancos-latinos. No se detectaron otras diferencias significativas por raza. Si bien los participantes bisexuales tenían probabilidades equivalentes de ser elegibles para PrEP, tenían probabilidades más bajas de recibir la primera prescripción de PrEP en comparación con los participantes homosexuales. Los participantes heterosexuales también tenían menores probabilidades de ser elegibles y de iniciarse en la PrEP. Las investigaciones futuras deben abordar los factores únicos que dan forma a los resultados relacionados con la PrEP entre las diversas poblaciones latinos.

LGBTQ2S+ childbearing individuals and perinatal mental health: A systematic review.

BACKGROUND: The perinatal period may uniquely impact the mental health and wellbeing of lesbian, gay, bisexual, transgender, queer, and Two-Spirit (LGBTQ2S+) childbearing individuals. OBJECTIVES: To characterise and synthesise the experiences of LGBTQ2S+ childbearing individuals regarding perinatal mental health, including symptomatology, access to care and care-seeking. SEARCH STRATEGY: We conducted and reported a systematic review following PRISMA guidelines of eight databases (EMBASE, MEDLINE-OVID, CINAHL, Scopus, Web of Science: Core Collection, Sociological Abstracts, Social Work Abstract, and PsycINFO) from inception to 1 March 2021. SELECTION CRITERIA: Original, peer-reviewed research related to LGBTQ2S+ mental health was eligible for inclusion if the study was specific to the perinatal period (defined as pregnancy planning, conception, pregnancy, childbirth, and first year postpartum; includes miscarriages, fertility treatments and surrogacy). DATA COLLECTION AND ANALYSIS: Findings were synthesised qualitatively via meta-aggregation using the Joanna Briggs Institute System for the Unified Management, Assessment and Review of Information (JBI SUMARI), and the ConQual approach. MAIN RESULTS: Our systematic search included 26 eligible studies encompassing 1199 LGBTQ2S+ childbearing participants. Using the JBI SUMARI approach, we reported 65 results, which we synthesised as six key findings. The studies described unique considerations for LGBTQ2S+ individuals' perinatal mental health, including heteronormativity, cisnormativity, isolation, exclusion from traditional pregnancy care, stigma, and distressing situations from the gendered nature of pregnancy. Many participants described a lack of knowledge from healthcare providers related to care for LGBTQ2S+ individuals. In addition, LGBTQ2S+ individuals described barriers to accessing mental healthcare and gaps in health systems. Strategies to improve care include provider education, avoidance of gendered language, documentation of correct pronouns, trauma-informed practices, cultural humility training and tailored care for LGBTQ2S+ people. CONCLUSIONS: Pregnancy, postpartum, and the perinatal period uniquely impacts the mental health and wellbeing of LGBTQ2S+individuals, largely due to systems-level inequities and exclusion from perinatal care. Healthcare providers should implement the identified strategies to improve perinatal care and address inequities.

Heterosexual Identification and Same-Sex Partnering: Prevalence and Attitudinal Characteristics in the USA.

This paper used the 2011-2017 National Survey of Family Growth to estimate population sizes and attitudinal characteristics of heterosexual-identified men who have sex with men (MSM) and women who have sex with women (WSW) aged 15-44 years. Analyses estimated population sizes in stages: after excluding respondents who reported only one lifetime same-sex partner, which happened before the age of 15; after excluding males who reported nonconsensual male-male sex; after excluding respondents who reported only one lifetime same-sex partner, regardless of the age at which that experience occurred; after excluding respondents who reported only two lifetime same-sex partners, the first of which occurred before age 15; and after excluding males who reported male-male sex work. The broadest criteria included many individuals with limited same-sex sexual histories or those who experienced nonconsensual sex or potentially coerced sex in youth. After excluding those respondents, analyses showed that heterosexual-identified MSM and WSW had a diversity of attitudes about gender and LGB rights; only a distinct minority were overtly homophobic and conservative. Researchers should carefully consider whether to include respondents who report unwanted sexual contact or sex at very young ages when they analyze sexual identity-behavior discordance or define sexual minority populations on the basis of behavior.

Sexual Orientation Change among Adolescents and Young Adults: A Systematic Review.

This article reviews research on changes in self-reported sexual orientation labels and associated health outcomes among adolescents and young adults. Using seven electronic databases and supplementary methods, we identified 30 studies for inclusion in the review, published between 2000 and 2020. This review aimed to summarize the approaches to measuring sexual orientation change; the prevalence, patterns, and directionality of changes in sexual identity; and how changes in sexual orientation relate to health outcomes among adolescents and youth adults. The reviewed studies lacked agreement in operationalization and assessment of sexual orientation changes. Prevalence of change in self-reported sexual orientation differed by birth sex, whereby cisgender female participants were more likely to report a change than male participants. In addition, adolescents and youth identifying with a nonheterosexual orientation or sexual minority at baseline were more likely to report a change in sexual orientation. Few studies reported on the impact of changes in sexual orientation on behavioral health outcomes. Adolescents who reported either nonheterosexual orientation at baseline or a shift toward nonheterosexual orientation had a greater likelihood of reporting depressive symptomology, suicidality, and substance use compared to those who did not report a change or reported consistent heterosexuality. Recommendations for future research and implications for practice are discussed.

Interpersonal Risk Factors, Sexual and Gender Minority Status, and Suicidal Ideation: Is BDSM Disclosure Protective?

Suicidal ideation is elevated among individuals who engage in BDSM practices and those with sexual and gender minority (SGM) identities. There is limited research on the intersectionality of these identities and how they relate to suicidal ideation, especially within a theoretical framework of suicide risk, such as the interpersonal theory of suicide. Thus, we tested the indirect relation between BDSM disclosure and suicidal ideation through thwarted belongingness and perceived burdensomeness, as well as the moderating role of SGM identity on these indirect associations. Participants were 125 (Mage = 28.27 years; 64% cisgender men) individuals recruited via online BDSM-related forums who endorsed BDSM involvement and recent suicidal ideation. Results indicated significant moderated mediation, such that BDSM disclosure was indirectly negatively related to suicidal ideation through lower thwarted belongingness, but not perceived burdensomeness, among SGM individuals. This was due to the significant relation between BDSM disclosure and thwarted belongingness. There were no significant moderated mediation or indirect effects related to perceived burdensomeness. We also provide supplemental analyses with positive ideation (i.e., positive thoughts toward life) as the criterion variable. In conclusion, BDSM disclosure appears to be protective against suicidal ideation through thwarted belongingness but only for SGM individuals. This work furthers our understanding of the impact of intersecting marginalized identities on suicide risk and resilience. Implications, limitations, and future directions are further discussed.
