RESUMO

Intersectionality, minority stress, and social ecological theories have all been important frameworks for understanding mechanisms that create and maintain sexual and gender minority health disparities. In this study, we integrated these frameworks to guide a grounded theory examination of identity-related experiences in specific settings among 33 Black, White, and Latino young sexual minority cisgender men who lived in Chicago. Analyses identified four key categories: Racism Manifests in Context- and Sexual Minority-Specific Ways, Sexual Orientation Can Mean Feeling Safe and Seen or Threatened and Alone, Gender is a Matter of Self-Expression, and Bodies Are Not Always Made to Fit In. Participants reported both identity-based privilege and marginalization as well as unique forms of minority stress at the intersection of specific identities. Across these categories, participants' experiences of their intersecting identities and associated forms of minority stress were embodied in their physical appearance, situated in specific neighborhoods and contexts, and co-constructed through their interpersonal interactions with others. Further, participants' narratives provide powerful insights about the nuanced ways in which young sexual minority men understand and negotiate their lived experiences. Findings highlight how experiences of identity and minority stress are both intersectional and located within specific social ecological contexts, which has important implications for research, clinical practice, and advocacy.

RESUMO

Although significant strides have been made for sexual and gender minority (SGM) rights in the United States, there continues to be opposition to SGM rights from many conservative Christians and political conservatives. In this study, we investigate this opposition by examining support for Christian hegemony (i.e., the idea that Christianity should be the norm and Christians should be in power in the United States) and unawareness of Christian privilege (i.e., unearned advantages for Christians) as religiopolitical variables that help to explain the association between Christian and political conservatism and opposition to a host of SGM rights (same-sex marriage, same-sex adoption, nondiscrimination policies in jobs and housing for SGMs, and bills regarding transgender public bathroom use). Based on structural equation modeling analysis with heterosexual cisgender Christian (n = 688) and Areligious (n = 327) students, we demonstrate that support for Christian hegemony and unawareness of Christian privilege help to explain the association between Christian and political conservatism and opposition to SGM rights. These findings advance our understanding of a new type of religious-based variable focused on religious power and privilege to help understand conservative religious and political opposition to SGM rights. Limitations, implications, and directions for future research also are discussed.

RESUMO

Stress experienced by either partner in a couple can have a negative impact on each partner's health, but most dyadic research on stress and health focuses on different-sex couples. We examined relationship functioning as a mechanism underlying the longitudinal actor and partner effects of stress on depression and substance use problems among 109 young male same-sex couples. There were significant indirect actor effects of internalized stigma and microaggressions on depression and alcohol use problems through negative relationship interactions. Participants who reported higher levels of internalized stigma and microaggressions reported more negative relationship interactions, which in turn was associated with reporting greater depression and alcohol use problems. In contrast, none of the indirect partner effects were significant. Findings implicate negative relationship interactions as a mechanism linking minority stress to health, but raise questions about the influence of partner stress on individual health among young male same-sex couples.

RESUMO

Lesbian, gay, bisexual, transgender, and queer (LGBTQ) youth and young adults almost inevitably "come out", or self-disclose their identity to others. Some LGBTQ youth are more uniformly "out", while others may disclose to some groups but not others. This selective disclosure is complicated on real name social media sites, which tend to encourage a unified presentation of self across social contexts. We explore these complications with a cohort of LBGTQ youth on Facebook (N = 199, Mage = 24.13). Herein we ask: How do LBGTQ youth manage the disclosure of their sexual orientation and/or gender identity to different people in their lives? Further, are there identifiable differences in the online social network structure for LGBTQ youth who manage outness in different ways? Finally, how do LGBTQ young people describe their experiences on Facebook? We answer these questions using a mixed methods approach, combining statistical cluster analysis, network visualization, and qualitative data. Our findings illustrate patterns in network structure by outness cluster type, highlighting both the work involved in managing one's online identity as well as the costs to (semi-) closeted individuals including a considerably lower overall network connectivity. In particular, outness to family characterized LGBTQ young people's experiences on Facebook.

RESUMO

OBJECTIVE: In different-sex couples, individual and partner stress can both have a negative impact on relationship functioning (actor and partner effects). Gay and bisexual men experience unique stress (sexual minority stress), but few studies have examined the effects of this stress on relationship functioning among young male couples. The current study examined (a) actor and partner effects of general and minority stress (internalized stigma, microaggressions, victimization, and outness) on relationship functioning (relationship quality and negative relationship interactions), (b) interactions between individual and partner stress as predictors of relationship functioning, and (c) dyadic coping and relationship length as moderators of actor and partner effects. METHOD: Actor-partner interdependence models were tested using data from 153 young male couples. RESULTS: There was strong support for actor effects. Higher general stress and internalized stigma were associated with lower relationship quality, but only for those in longer relationships. Additionally, higher general stress, internalized stigma, and microaggressions, and lower outness, were associated with more negative relationship interactions. There was limited support for partner effects. Having a partner with higher internalized stigma was associated with more negative relationship interactions, but none of the other partner effects were significant. There was no support for individual and partner stress interacting to predict relationship functioning or for dyadic coping as a stress buffer. CONCLUSIONS: Findings highlight the influence of one's own experiences of general and minority stress on relationship functioning, but raise questions about how partner stress influences relationship functioning among young male couples.

RESUMO

Minority stress theory has widespread research support in explaining health disparities experienced by sexual and gender minorities. However, less is known about how minority stress impacts multiply marginalized groups, such as lesbian, gay, bisexual, and transgender people of color (LGBT POC). Also, although research has documented resilience in the face of minority stress at the individual level, research is needed that examines macro-level processes such as community resilience (Meyer, 2015). In the current study, we integrate minority stress theory and intersectionality theory to examine multiple minority stress (i.e., racial/ethnic stigma in LGBT spaces and LGBT stigma in one's neighborhood) and community resilience (i.e., connection to LGBT community) among sexual minority men of different racial/ethnic groups who use a geosocial networking application for meeting sexual partners. Results showed that Black sexual minority men reported the highest levels of racial/ethnic stigma in LGBT spaces and White sexual minority men reported the lowest levels, with Asian and Hispanic/Latino men falling in between. Consistent with minority stress theory, racial/ethnic stigma in LGBT spaces and LGBT stigma in one's neighborhood were associated with greater stress for sexual minority men of all racial/ethnic groups. However, connection to LGBT community played more central role in mediating the relationship between stigma and stress for White than POC sexual minority men. Results suggest that minority stress and community resilience processes may differ for White and POC sexual minority men. Potential processes driving these differences and implications for minority stress theory are discussed.

RESUMO

The majority of published research on transgender health focuses on associations between external minority stressors (e.g., discrimination) and health. Little is known about how internal minority stressors (e.g., identity concealment and expecting rejection) might predict HIV disparities. The current study addresses this gap by examining the association between external and internal minority stressors and sexual risk behaviors and HIV testing history in a sample of 300 transgender adults across the U.S. Transgender-related discrimination and expecting rejection were associated with sexual risk behaviors. When controlling for covariates, none of the minority stressors were associated with HIV testing. Results illustrate how minority stress, both external and internal, may operate uniquely for transgender individuals.

RESUMO

This article presents the case of a Chinese-American adolescent with a significant trauma history who was questioning her sexual and gender identities. The implications of the client's intersecting identities for case conceptualization and treatment are considered within the framework of affirmative practices for sexual and gender minority (SGM) clients. The impacts of stress and trauma on this client's experiences-and SGM clients more broadly-are also considered, particularly with respect to how this client understood and negotiated her experiences of relational trauma. This case is intended to illustrate some best practices with SGM clients within an intersectional framework which underscores the importance of multiple salient cultural identities.

RESUMO

The rise of social networking sites (SNSs) has created new contexts within which lesbian, gay, bisexual, transgender, and queer (LGBTQ) youth and young adults manage their social identities and relationships. On one hand, SNSs provide important social support; on the other, they comprise another realm for victimization and discrimination. Context collapse refers to the ways diverse subgroups (e.g., family, co-workers) are often united in Facebook networks, which presents unique challenges related to outness. In this study, we examine the Facebook contexts of a cohort of LGBTQ youth and young adults with regard to outness, victimization, social support, and psychological distress by first examining descriptive statistics and correlations, and then testing a series of multiple regressions in an analytic sample of 175 (Mage = 24.02 years) LGBTQ youth. Participants reported levels of daily Facebook use comparable to other samples of non-LGBTQ youth; however, they reported greater use of security controls, which may function as a tool for managing outness. Participants reported slightly lower outness across relational subgroups on Facebook, and associations between outness to relational subgroups were slightly stronger on Facebook, illustrating the potential impact of context collapse. Regression results showed that great victimization, cyberbullying, and the offering of support online were positively associated with psychological distress. Study findings illuminate how LGBTQ youth use and manage their identities on Facebook and highlight the importance of online contexts in shaping wellbeing for LGBtQ outh and young adults.

RESUMO

Teacher-directed violence is a common, yet understudied, phenomenon. Perpetrators of violence against teachers include not just students, but also administrators, parents, and colleagues. Administrators are key stakeholders when it comes to shaping school climate and safety that can reduce or increase the negative impact of violence against teachers. In this study, 237 teachers' qualitative responses from a larger sample of 2,431 anonymous, online survey responses were examined to better understand their experiences with incidents of violence and how administrators played a role in these experiences. Results reveal that lack of administrator support negatively impacts teachers at multiple levels, including teachers' feelings (individual); challenges associated with addressing issues related to students, parents, and other perpetrators (interpersonal); and school systems and policies (organizational). This study highlights the importance of administrative support and illustrates how administrators' actions and inactions can have ripple effects at each level of the school microcosm. Implications for research, practice, and policy are discussed.

RESUMO

PURPOSE: Lesbian, gay, bisexual, and transgender (LGBT) adolescents are at greater risk for mental health problems than their heterosexual peers, in part due to victimization. Social support, particularly from families, has been identified as an important promotive factor. However, little is known about how LGBT youth experience multiple forms of support or how early support predicts mental health across adolescence and into young adulthood. METHODS: In an analytic sample of 232 LGBT youth aged 16-20 years at baseline across 5.5 years, we compared developmental trajectories of psychological distress between three empirically derived social support cluster types at baseline: those who reported uniformly low support, those who reported uniformly high support, and those who reported nonfamily support (i.e., high peer and significant other but low family support). RESULTS: Longitudinal multilevel modeling, controlling for age, victimization, and social support at each wave, indicated key differences between cluster types. Youth in the low and nonfamily support clusters reported greater distress across all time points relative to youth in the high support cluster; however, they also showed a sharper decline in distress. Youth in the nonfamily cluster gained family support across adolescence, such that they resembled youth in the high support cluster by early adulthood. CONCLUSIONS: Findings underscore the importance of family support for LGBT youth. Youth who lack family support, but who have other forms of support, report a decrease in psychological distress and an increase in family support across adolescence. Youth who are low in all forms of support continue to exhibit high distress.

RESUMO

The counterspaces framework articulated by Case and Hunter (2012), follows from community psychology's long-standing interest in the potential for settings to promote well-being and liberatory responses to oppression. This framework proposes that certain settings (i.e., "counterspaces") facilitate a specific set of processes that promote the well-being of marginalized groups. We argue that an intersectional analysis is crucial to understand whether and how counterspaces achieve these goals. We draw from literature on safe spaces and present a case study of the Michigan Womyn's Music Festival (Michfest) to illustrate the value of an intersectional analysis and explore how these processes operate. Based on 20 in-person interviews, 23 responses to an online survey, and ethnographic field notes, we show how Michfest was characterized by a particular intersection of identities at the setting level, and intersectional diversity complicated experiences at the individual level. Moreover, intersectional identities provided opportunities for dialogue and change at the setting level, including the creation of counterspaces within counterspaces. Overall, we demonstrate the need to attend to intersectionality in counterspaces, and more broadly in how we conceptualize settings in community psychology.

RESUMO

PURPOSE: The purpose of this study is to examine rates of and risk factors for obesity in a community sample of African American sexual minority women (SMW). METHODS: Data were collected using self-administered paper-and-pencil survey questionnaires (n = 219). RESULTS: Participants were primarily middle aged (M = 40.1; standard deviation [SD] = 10.5 years), well educated (56.9% with a college education and above), insured (82.3%), and had a median income range from $30,000 to $39,999. The mean body mass index (BMI) of the sample was 31.6 (SD = 8.0). Based on BMI scores, over half of the participants were identified as obese (53.9%) and 25.6% were overweight. A number of comorbid illnesses were reported that could be exacerbated by excess weight, including arthritis (21.3%), adult-onset diabetes (4.9%), back problems (23.2%), high cholesterol (15.3%), high blood pressure (19.2%), and heart disease (12%). Multiple risk factors for obesity were observed, including infrequent exercise (<3 times/week = 50.9%), low levels of fruit/vegetable consumption (≤1 serving daily = 39.9%), and frequent consumption of red meat (≥3 times/week = 21.2%). Psychosocial risk factors were also reported, including "eating in response to stress" (46.0%). Depression scores predicted eating in response to stress. One-third of the sample reported interest in weight management interventions. CONCLUSIONS: African American SMW report high rates of obesity, chronic health conditions exacerbated by weight, and health and dietary behaviors that increase risk for weight-related health disparities. These study findings have implications for additional research and intervention development.

RESUMO

The United States is trending toward more permissiveness regarding recreational and medicinal marijuana (MJ). Many conditions for which MJ is recommended, prescribed, or self-prescribed are symptoms that advanced practice nurses address daily. Yet, the silence of nursing scientists on ethics, practices, and policies regarding such clinical decisions is deafening. This is but one of many contradictions about MJ use that we discuss in this article. We do not propose to resolve these contradictions; that is left to the community of nurse scientists in interprofessional discourse. Collectively, we must explore these contradictions and, through evidence-based policy recommendations, overcome the silence about how providers view MJ, how it might be helpful, its risks, and cultural shifts that have accompanied a changed political/legal environment. Long term, we must close the gaps in the nursing knowledge base regarding MJ as it affects users and how it is used interventionally.

RESUMO

Mass spectrometry (MS)-based proteomic approaches have largely facilitated our systemic understanding of cellular processes and biological functions. Cutoffs in protein expression fold changes (FCs) are often arbitrarily determined in MS-based quantification with no demonstrable determination of small magnitude changes in protein expression. Therefore, many biological insights may remain veiled due to high FC cutoffs. Herein, we employ the intestinal epithelial cell (IEC) line Caco-2 as a model system to demonstrate the dynamicity of tandem-mass-tag (TMT) labeling over a range of 5-40% changes in protein abundance, with the variance controls of ± 5% FC for around 95% of TMT ratios when sampling 9-12 biological replicates. We further applied this procedure to examine the temporal proteome of Caco-2 cells upon exposure to human whey proteins (WP). Pathway assessments predict subtle effects due to WP in moderating xenobiotic metabolism, promoting proliferation and various other cellular functions in differentiating enterocyte-like Caco-2 cells. This demonstration of a sensitive MS approach may open up new perspectives in the system-wide exploration of elusive or transient biological effects by facilitating scrutiny of narrow windows of proteome abundance changes. Furthermore, we anticipate this study will encourage more investigations of WP on infant gastrointestinal tract development.

RESUMO

The rise of queer and transgender studies has greatly contributed to feminist and lesbian understandings of sex, gender, and sexuality and also has resulted in rifts, tensions, and border wars. One such tension is around the inclusion of trans women in women-only space, such as the Michigan Womyn's Music Festival (Michfest). In this ethnophenomenological study, we interviewed and surveyed 43 cisgender women who attended Michfest in 2013. Participants had a variety of perspectives on trans inclusion and on the dialogue surrounding it, and these paralleled intersections, frictions, and tensions between feminism, queer theory, and transgender studies.

RESUMO

Stigma and stress may place HIV-positive men who have sex with men (HIV+ MSM) at risk for depression. Additionally, HIV+ MSM might utilize multiple HIV-related services as a way to gain support for, and more effectively manage, HIV-related stressors. Although prior research has demonstrated that depression severity and utilizing support services are associated with functional or dysfunctional coping strategies, researchers have not investigated the impact of different coping combinations-specifically, the concurrent use of functional and dysfunctional strategies-in this population. Thus, we explored (1) how items on one measure of coping, the Brief COPE, capture HIV-related coping of HIV+ MSM using Principal Components Analysis, (2) how HIV+ MSM's coping groups into unique combinations, and (3) how these coping combinations relate to depression and the scope of HIV-related support service utilization. Our sample consisted of 170 HIV+ MSM engaged with medical care. Results indicated the use of both functional and dysfunctional coping strategies. Unique combinations of functional and dysfunctional strategies showed differential associations with depression and the extent of HIV-related support service utilization. Specifically, individuals who engaged in low levels of both functional and dysfunctional coping, compared to individuals who more frequently engaged in functional coping strategies, were significantly less likely to utilize a range of critical HIV-related services. Individuals who reported frequent use of dysfunctional coping strategies, regardless of functional coping strategy use, reported higher levels of depression. Therefore, providers should continue to focus more closely on identifying functional coping strategies and reducing dysfunctional coping when working with HIV+ MSM.

RESUMO

Lunasin, a soybean bioactive peptide, has both chemopreventive and chemotherapeutic activities. The aim of this study was to determine the chemotherapeutic potential of lunasin against human lung cancer. Treatment of non-small cell lung cancer (NSCLC) cells with highly purified soybean-derived lunasin caused limited, cell-line specific anti-proliferative effects on anchorage-dependent growth whereas two normal bronchial epithelial cell lines were unaffected. Lunasin's antiproliferative effects were potentiated upon utilization of anchorage-independent conditions. Furthermore, NSCLC cell lines that were unaffected by lunasin in anchorage-dependent assays exhibited a dose-dependent inhibition in colony formation or colony size. Mouse xenograft studies revealed that 30 mg lunasin/kg body weight per day decreased NSCLC H1299 tumor volume by 63.0% at day 32. Mechanistic studies using cultured NSCLC H661 cells showed that lunasin inhibited cell cycle progression at the G1/S phase interface without inducing apoptosis. Immunoblot analyses of key cell-cycle proteins demonstrated that lunasin altered the expression of the G1 specific cyclin-dependent kinase complex components, increased levels of p27Kip1, reduced levels of phosphorylated Akt, and ultimately inhibited the sequential phosphorylation of the retinoblastoma protein (RB). These results establish for the first time that lunasin can inhibit NSCLC proliferation by suppressing cell-cycle dependent phosphorylation of RB.

RESUMO

PURPOSE: Lesbian, gay, bisexual, and transgender (LGBT) youth show increased risk for a number of negative mental health outcomes, which research has linked to minority stressors such as victimization. Further, social support promotes positive mental health outcomes for LGBT youth, and different sources of social support show differential relationships with mental health outcomes. However, little is known about how combinations of different sources of support impact mental health. METHODS: In the present study, we identify clusters of family, peer, and significant other social support and then examine demographic and mental health differences by cluster in an analytic sample of 232 LGBT youth between the ages of 16 and 20 years. RESULTS: Using k-means cluster analysis, three social support cluster types were identified: high support (44.0% of participants), low support (21.6%), and non-family support (34.5%). A series of chi-square tests were used to examine demographic differences between these clusters, which were found for socio-economic status (SES). Regression analyses indicated that, while controlling for victimization, individuals within the three clusters showed different relationships with multiple mental health outcomes: loneliness, hopelessness, depression, anxiety, somatization, general symptom severity, and symptoms of major depressive disorder (MDD). CONCLUSION: Findings suggest the combinations of sources of support LGBT youth receive are related to their mental health. Higher SES youth are more likely to receive support from family, peers, and significant others. For most mental health outcomes, family support appears to be an especially relevant and important source of support to target for LGBT youth.
