Sex differences in the development of mild cognitive impairment and probable Alzheimer’s disease as predicted by hippocampal volume or white matter hyperintensities

This study examined biological sex differences in the development of mild cognitive impairment (MCI) and probable Alzheimer’s disease (AD) development as predicted by changes in the hippocampus or white matter hyperintensities. A secondary data analysis of the National Alzheimer’s Coordinating Center Uniform Data Set was conducted. We selected samples of participants with normal cognition at baseline who progressed to MCI (n = 483) and those who progressed to probable AD (n = 211) to determine if hippocampal volume or white matter hyperintensities (WMH) at baseline predicted progression to probable AD or MCI and whether the rate of progression differed between men and women. The survival analyses indicated that changes in hippocampal volumes affected the progression to probable AD (HR = 0.535, 95% CI [0.300–0.953]) only among women. White men had an increased rate of progression to AD (HR = 4.396, CI [1.012–19.08]; HR = 4.665, 95% CI [1.072–20.29]) compared to men in other race and ethnic groups. Among women, increases in hippocampal volume ratio led to decreased rates of progressing to MCI (HR = 0.386, 95% CI [0.166–0.901]). Increased WMH among men led to faster progression to MCI (HR = 1.048. 95% CI [1.011–1.086]). Women and men who were older at baseline were more likely to progress to MCI. In addition, results from longitudinal analyses showed that women with a higher CDR global score, older age at baseline, or more disinhibition symptoms experienced higher odds of MCI development. Changes in hippocampal volumes affect the progression to or odds of probable AD (and MCI) more so among women than men, while changes in WMH affected the progression to MCI only among men.     

Reactions to Transgender Women and Men in Public Restrooms: Correlates and Gender Differences

This study examined reactions to transgender people in public restrooms. Participants (n = 158) completed measures of essentialism and trait aggression and read scenarios where they imagined sharing a restroom with a transwoman or a transman. Participants indicated which restroom targets should use and rated potential negative reactions. Results indicate that targets were assigned to restrooms corresponding to birth sex rather than chosen identity. Women’s reactions to transgender women were more negative than men’s; men were more negative in reactions toward transmen. Essentialism predicted some (but not all) reactions for all participants. Among women, trait aggression predicted negative reactions, but only to transmen. Among men, aggression predicted negative reactions, but only toward transwomen. This suggests that despite views that transgender people belong in birth-sex restrooms, men and women’s trait aggression predicts negative reactions toward them in such instances.     

The Role of Gay Identity Confusion and Outness in Sex-Seeking on Mobile Dating Apps Among Men Who Have Sex With Men: A Conditional Process Analysis

Mobile dating apps are now a popular platform for men who have sex with men (MSM) to connect with others. Based on the uses and gratifications (U&G) theory, this study explores the relationship between sex-seeking and the number of casual sex partners met through MSM-based mobile dating apps (Grindr, Jack’d, and SCRUFF). The conditional process analysis (N = 401) shows that this relationship was significant and was mediated by the intensity of app use. That is, sex-seeking indirectly affected the number of casual sex partners through the intensity of app use. Furthermore, gay identity confusion and outness to the world moderated this indirect effect: it was stronger when the user was either more confused about his sexuality or was less out to the world. This research introduces an alternative way to incorporate psychographics variables into the U&G framework.     

“Hedge Your Bets”: Technology’s Role in Young Gay Men’s Relationship Challenges

Technology is playing an increasingly pervasive role among young gay men in the process of meeting potential romantic or sexual partners. We investigated challenges posed by technology related to young gay men’s relationships. Focus groups (n = 9) of young gay men aged 18–24 (n = 43) were transcribed verbatim, and thematic analysis was used to identify two major themes regarding challenges to relationship development and maintenance. Subthemes include unrealistic expectations of relationships, inauthentic self-presentation online, sexual primacy over romance, increased opportunities for infidelity, and jealousy. The implications of this study for sexual education and sexual health promotion are discussed.     

Is Gaydar Affected by Attitudes Toward Homosexuality? Confidence,Labeling Bias,and Accuracy

Previous research has largely ignored the relationship between sexual orientation judgement accuracy, confidence, and attitudes toward homosexuality. In an online study, participants (N = 269) judged the sexual orientation of homosexual and heterosexual targets presented via a series of facial photographs. Participants also indicated their confidence in each judgment and completed the Modern Homonegativity Scale (Morrison & Morrison, 2002). We found that (1) homosexual men and heterosexual women were more accurate when judging photographs of women as opposed to photographs of men, and (2) in heterosexual men, negative attitudes toward homosexual men predicted confidence and bias when rating men’s photographs. Findings indicate that homosexual men and heterosexual women are similar in terms of accuracy in judging women’s sexuality. Further, especially in men, homophobia is associated with cognitive biases in labeling other men but does not have a relationship with increased accuracy.     

It’s Not Me,It’s You: Perceptions of Partner Body Image Preferences Associated With Eating Disorder Symptoms in Gay and Heterosexual Men

This study explored perceptions of partner body image preferences and symptoms of disordered eating in gay and heterosexual men. Participants were male college students (n = 201; M age = 20.46), and over one third identified as gay. We compared discrepancies between participants’ current and ideal body type and participants’ current body type and the body type they believed they should have to attract a dating partner. For gay men, the discrepancy between their current body and the body they believed they should have to attract a dating partner was significantly greater than the discrepancy between their current and ideal body types. In gay and heterosexual men, the discrepancy between current body and the body they believed they should have to attract a dating partner predicted eating, shape, and weight concern. Results suggest that perceptions of partner body image preferences may contribute to eating disorder pathology in men.     

Why do I dread looking old?: A test of social identity theory,terror management theory,and the double standard of aging

ABSTRACT

Outward appearance is one of the means by which age is determined, and fear of looking old may stem from fears about social identity and death. This study explored how social identity theory and terror management theory may help to explain the dread of looking old. University students from the United States, England, and Australia (N = 1,042) completed a questionnaire regarding their attitudes about aging and older adults. Results indicated that sex, age, beliefs about personal aging, and death anxiety explained 30.4% of the variance for participants’ dread of looking old. Theoretical hypotheses were supported by our findings.     

Difference in Condom Use Between Bear Concordant and Discordant Dyads During the Last Anal Sex Event

The purpose of this study was to understand how bear identity influenced condom use during the last anal sex event. Participants were recruited to complete an online, anonymous self-report survey through bear-related sexual and social networking websites. A total of 1,080 men who identified as gay or bisexual and as a member of the bear community and were 18 years or older completed the survey. Overall, fewer than a third of men reported condom use during the most recent receptive (28%) and insertive (30%) anal sex event. Men in bear concordant pairings were less likely to use a condom during receptive and insertive anal sex compared to those is discordant pairings (p < .05). Findings suggest that bear identity concordance influences condom use during anal sex after accounting for an individual’s relationship to their most recent partner as well as other confounding variables.     

Exploring First Sexual Intercourse,Sexual Orientation,and Sexual Health in Men

In this study the characteristics of the sexual debut of men who have sex with men (MSM) and men who have sex with women (MSW) age 35 or younger (N = 1,201) were compared with one another. We investigated whether these characteristics were associated with sexual health and behavior, and to what extent. Compared to MSW, MSM tended to be older when they had their first sexual intercourse; their first sex partner was older, they felt less ready, and they experienced more pain. We also found that they reported a higher number of lifetime sexual partners and less condom use compared to MSW. Similarities were also ascertained, such as the fact that individuals from both groups do not differ significantly regarding how they experienced their first sexual intercourse emotionally. Many differences between these groups should not always be seen as problematic, whereas others still indicate a need for targeted interventions.     

The Interrelations Between Internalized Homophobia,Depressive Symptoms,and Suicidal Ideation Among Australian Gay Men,Lesbians, and Bisexual Women

ABSTRACT

Internalized homophobia has been linked to depression among gay men, lesbians, and bisexuals. Relatively little research has investigated the link between internalized homophobia and suicidal thoughts and behaviors. The current research investigated the interrelations among internalized homophobia, depressive symptoms, and suicidal ideation by testing additive, mediation, and moderation models. Self-identified Australian gay men (n = 360), lesbians (n = 444), and bisexual women (n = 114) completed the Internalized Homophobia Scale, the Center for Epidemiological Studies Depression Scale, and the suicide subscale of the General Health Questionnaire. Results supported the additive and partial mediation models for gay men and the mediation and moderation models for lesbians. None of the models were supported for bisexual women. The findings imply that clinicians should focus on reducing internalized homophobia and depressive symptoms among gay men and lesbians, and depressive symptoms among bisexual women, to reduce suicidal ideation.     

Assessing the Gender Invariance of the Modern Homonegativity Scale

The measurement invariance of the Modern Homonegativity Scale (MHS) was examined among heterosexual female (n = 449) and male (n = 329) university students who were predominantly Mexican American. The MHS demonstrated full invariance of factor loadings and partial invariance of latent intercepts. At the latent mean level, heterosexual men compared to heterosexual women held more negative attitudes toward both gay men and lesbian women. There were no latent mean differences in attitudes toward gay men and lesbian women when rated by either heterosexual men or heterosexual women. The MHS can be used by heterosexual men and heterosexual women to assess their homonegativity.     

“She Finally Smiles … for Real”: Reducing Depressive Symptoms and Bolstering Resilience Through a Camp Intervention for LGBTQ Youth

ABSTRACT

While summer camps are a recognized evidence-based strategy for building social and emotional skills among youth (U.S. Centers for Disease Control and Prevention [CDC], 2009), no known studies have evaluated the effects of camp programming for LGBTQ youth in the United States. This pilot study evaluates a novel program (Brave Trails) for LGBTQ youth ages 12 to 20, using a pre-post camper survey (N = 56) and a post-camp parent survey (N = 54). Results show campers experienced increases in identity affirmation and hope and a reduction in depressive symptoms. Regression analyses found changes in identity affirmation predicted reductions in depressive symptoms and increases in resilience. Additionally, campers’ experience of key camp programming features predicted changes in depressive symptoms. Findings from the parent survey were consistent with camper survey results. Theoretical and practical implications are discussed.     

PrEP Awareness in the Context of HIV/AIDS Conspiracy Beliefs Among Black/African American and Hispanic/Latino MSM in Three Urban US Cities

ABSTRACT

We examined HIV conspiracy beliefs and PrEP awareness in a convenience sample of minority MSM. Participants in three cities completed a behavioral self-assessment on sociodemographics, PrEP awareness, and HIV/AIDS conspiracy beliefs. HIV/AIDS conspiracy beliefs were more common among Black than Latino MSM (58% vs. 42%, p < .05), and among younger men than older men (age 18–29 (50%), 30–39 (22%), 40+ (28%); p < .05). PrEP awareness co-occurred with conspiracy belief less (37%) than with non-belief (63%, p < .05), persisting in multivariable regression (aOR = 0.52, 95% CI = 0.38–0.71). This relationship suggests that current HIV care and prevention messaging is either inaccessible or not credible to some minority subpopulations.     

When “They” Become “Us”: The Effect of Time and Ingroup Identity on Perceptions of Gay and Lesbian Group Members

ABSTRACT

Prejudice change manipulations rarely produce the expected attitude change effects. Our research suggests that attitude change depends on time-dependent memory consolidation processes. This study tested the effects of group information and time on perceptions of gays and lesbians. Heterosexual participants (N = 90) were randomly assigned to a condition where their ingroup, or an outgroup, included gay and lesbian individuals. We measured participants’ gay and lesbian political attitudes and evaluations of the groups’ members at a short or long delay. Results showed no effect of our manipulations on political attitudes, F(1, 86) = 0.14, p = .72. Contrary to predictions, participants evaluated gay and lesbian ingroup members less positively at the long versus short delay, t(49) = 3.72, p = .0004, d = 1.01. Results suggest that members of stigmatized groups are perceived more negatively when associated with one’s ingroup.     

Psychometric and Faciometric Support for Observable Facial Feminization in Gay Men

ABSTRACT

Though male homosexuality appears to be evolutionarily paradoxical, phenotypic feminization has been offered as a route for three current models positing a genetic basis for male homosexuality. We tested whether facial feminization is observable in gay men in two studies. In Study 1, using two composite images of gay and of heterosexual men, naive participants (N = 308) rated the “gay” face more highly on stereotypically feminine traits and actual femininity and the “heterosexual” face more highly on stereotypically masculine traits and actual masculinity. In Study 2, faciometrics of 428 Internet images of gay (N = 219) and heterosexual men were analyzed along six sexually dimorphic ratios. The faciometrics of gay men were more feminine, both in gestalt terms and for five of the six individual traits. The studies offer objective support for a more feminized facial phenotype in gay males that is difficult to explain through cultural or behavioral cues.     

Resistance training is linked to heightened positive motivational state and lower negative affect among healthy women aged 65–70

Resistance training (RT) improves overall health, but the psychological effects of RT in healthy old adults have not been tested. The aim of this study was to investigate a sample of 65–70-year-old healthy and physically active women to assess their sense of coherence, health-related quality of life, hope, and affect, before and after taking part in a 24-week RT intervention (N = 14), compared to controls (N = 18). Findings showed a significant increase in hope (p = 0.013) and a significant decrease in negative affect (p = 0.002). Starting RT after age 65 does not appear to negatively impact on women’s psychological health but seems to be associated with important psychological health benefits.     

Self-Perceived Parental Role and Mental Health Concomitants Among Israeli Gay and Heterosexual Fathers

ABSTRACT

In this study we examined the association between self-perceived parental role and adverse mental health (indicated by depressive symptoms, neuroticism, and negative affect) in a sample of 82 Israeli gay fathers (Mean age = 39.57, SD = 6.70) that were individually matched with 82 heterosexual fathers (Mean age = 39.11, SD = 7.88). Results showed that although self-perceived parental role was associated with adverse mental health, this association was moderated by sexual orientation, such that a significant negative association between self-perceived parental role and adverse mental health was evident only among gay fathers. The findings are understood by features of gay fatherhood, which is intentional and purposeful, and usually achieved after contending with particular difficulties in the journey to fatherhood. These features presumably shape the perceived parental role, and thus may link more strongly with lower levels of adverse mental health among gay fathers, compared to heterosexual fathers.     

Cultivating Professional Allies for Sexual Minority Youth: A Community-Based Educational Intervention

Sexual minority youth (SMY) face multiple risks in their daily lives that may influence their need for supportive care. Health and social service providers have unique opportunities to provide culturally competent services to these youth. This article describes a community-based educational intervention created to increase providers’ knowledge, skills, and intention to support SMY. Based on the Information-Motivation-Behavioral Skills model, this pilot study found that for a diverse sample of multidisciplinary professionals (n = 2,850), the odds of behavioral intention (BI) to support SMY were significantly higher when trainings were relevant to the professionals’ experience (OR = 1.3), were sensitive (OR = 1.3), developed skills (OR = 1.1), and incorporated policy (OR = 1.2). Implications for the delivery of community-based trainings are provided.     

A Meta-Analytic Review of the Association Between Disgust and Prejudice Toward Gay Men

ABSTRACT

A sizeable number of studies have documented a relationship between heterosexual persons’ experience of disgust (measured as an individual difference variable or induced experimentally) and prejudice toward gay men (i.e., homonegativity). Yet, to date, no one has attempted to meta-analytically review this corpus of research. We address this gap by conducting a meta-analysis of published and unpublished work examining heterosexual men and women’s disgust and their homonegativity toward gay men. Fourteen articles (12 published, two unpublished) containing 17 studies were analyzed (N = 7,322). The average effect size for disgust sensitivity studies was moderate to large (d = 0.64), whereas for disgust induction studies, the effect was large (d = 0.77). No evidence of effect size heterogeneity emerged. Future directions and recommendations for methodological improvements are outlined.     

“You Have to Keep Yourself Hidden”: Perspectives From Malaysian Malay-Muslim Men Who Have Sex With Men on Policy,Network, Community,and Individual Influences on HIV Risk

ABSTRACT

Malay-Muslim men who have sex with men (MSM) are marginalized and hidden in Malaysia, a predominantly Muslim country in southeast Asia. We explored the policy, network, community, and individual factors related to HIV infection among Malay-Muslim MSM through 26 in-depth interviews and one focus group discussion (n = 5) conducted in Kuala Lumpur and Kota Bharu between October 2013 and January 2014. As religion plays an important role in their lives, participants viewed homosexuality as a sin. Low risk perception and misconceptions about HIV/AIDS were common, and most participants expressed reluctance to consult a doctor unless they had symptoms. Additionally, buying condoms was embarrassing and anxiety-producing. Fear of discrimination by health care providers and community hindered participants from disclosing sexual behaviors and accessing health services. Homophobic comments and policies by the government and religious leaders were concerns of participants. A safe and enabling environment is needed to reduce HIV risks among Malay-Muslim MSM.
